HAPPY BIRTHDAY CMX SERIES

We can’t believe it’s been 12 months since the launch of our new energy-dense batteries for Hi-tech portable medical equipment at Compamed 2014, and just how successful the CMX Series has been over the past year. 

The new smart battery range fulfils the needs of manufacturers of high powered medical devices. The CMX series really packs a punch - offering high energy density along with high power discharge. Medical OEMs (Original Equipment Manufacturers) are now able to produce innovative portable devices without compromising on safety and reliability in life-critical applications.

The medical market is a challenging environment, and understandably so. With people's lives on the line it is essential that medical practitioners can rely on their equipment to perform under pressure. The rise in the use of portable devices such as acute ventilators, anaesthesia workstations and intra-oral scanners has left many medical OEMs struggling to keep pace in the market.  The CMX Series of batteries and chargers has been designed specifically for medical OEMs following extensive research and discussion with customers and hospitals.

“Part of our branded Entellion range, the CMX meets stringent regulations, demanding development schedules and innovation aims, whilst minimising unit costs," explained Neil Oliver, technical marketing manager at Accutronics. “The CMX Series, as with our other Entellion products, bridge the gap between custom and standard batteries and chargers”.

The seven batteries in the CMX range use three different cell types to provide specific performance attributes which are required for the medical device market.  Smart features of the CMX series include active and passive protection circuits that prevent over-temperature, over and under-voltage, overload and short circuit.  Forming an essential part of its medical device operation, smart power management means the battery only requests charge when needed and shuts down when not being used. Accurate fuel gauging is possible to 1% through an LCD display, further enhancing reliability.

CMX series batteries comply with regulatory certifications necessary for use in medical devices. In terms of safety they meet the requirements of both UL2054 (2nd edition) and IEC62133:2012 (2nd edition), the latter being a mandatory requirement for medical devices being certified to IEC60601-1 (3rd edition).  They also meet the requirements of The Transport of Dangerous Goods, Methods of Tests and Criteria, UN ST/SG/AC.10.11 Rev5 Section 38.3 which is a mandatory requirement for the transportation of Lithium ion batteries.
 
Hospitals can now perform routine power management checks without having to remove the medical device from service using the smart charger that accompanies the CMX battery. A single charger can be used for different sized batteries, because the two devices automatically communicate exact voltage requirements.

Whether batteries or chargers, the Entellion range is available off-the shelf or can be easily customised to meet particular OEM requirements. Options include product labelling and case colours, software setup and SHA-1 algorithmic security, which prevents counterfeit batteries being used under fraudulent warranty claims.

Going mini at world's biggest medical show

Mini battery for portable medical devices smaller than credit card

The doors have now opened at Compamed in Düsseldorf, Germany. Co-hosted with Medica, Compamed is the world's largest medical technology (MedTech) trade show which runs from November 16-19. This year Accutronics are exhibiting its smallest medical battery and charger the CC1150 mini credit card battery and CX3050 desktop charger.   These small batteries target the growing demand for portable medical devices used in hospitals and in home healthcare and can be seen on stand H18 in Hall 8b.

The event will see 728 companies from 37 countries come together with over 17,000 trade visitors in medical technology sectors ranging from nanotechnology and test and instrumentation to certification and medical manufacturing.

The CC1150 mini credit card battery is a 3.7V, 1.15h (4.2Wh) Lithium-ion 2.0A battery measuring just 54mm square and 9.5mm high, occupying just half the footprint of a standard credit card.

Rare in batteries of this size, the CC1150 also features an active electronic protection system that prevents overcharge, over discharge and short circuit, crucial for hands-on environments such as hospitals. In addition, the built-in, high accuracy, impedance tracking, fuel gauge means the CC1150 can track battery status information including remaining capacity (mAh), remaining runtime, percentage charge, battery voltage (mV) and temperature.

"Even though medical devices are getting smaller, battery OEMs (Original Equipment Manufacturers) have been slow to provide devices that pack the same functionality into smaller form factors," explained Neil Oliver, technical marketing manager at Accutronics. "This is why we've developed the CC1150 mini credit card battery and CX3050 charger.

"OEMs can reduce their testing costs and improve return on investment by specifying these units. This range is fully tested to meet the international requirements of IEC62133 and UN38.3 and, because the battery is under 100Wh, further time and costs can be saved during transportation."

The CC1150 mini credit card battery is accompanied by the CX3050, a slimline desktop charger, which allows the battery to be charged separately from the device. "There is a trend among many medical OEMs to use embedded batteries," continued Oliver. "However, for medical devices, it's not always practical to take the entire device to a charging point. For these situations, simply swapping the empty battery for a fully charged one, allows devices to remain in continuous use - this is where our charger really comes into its own."

The CX3050 desktop charger is supplied with a 100-240VAC wall mounted power supply, charging the battery in just 2.5 hours. Built in LEDs indicate power, charging, fully charged and fault conditions. Furthermore, interchangeable AC blades mean the units can be used in the UK, Europe, North America, Australia and China. The CX3050 is also pre-qualified with certification for UL and IEC60950-1 as well as being CE marked. Customers can further customise the casing, labelling and packaging.

Come to meet us on our stand where you can also view many of our custom medical battery and charger solutions (Accupro) and other Entellion products and discuss your upcoming projects - Stand H18 in Hall 8b from 16-19 November.

You may also like to visit the Suppliers Forum in Hall 8b where Neil Oliver will be providing a presentation on 'The Lithium Ion Regulatory Maze' on Tuesday 17th November at 13:15 hrs.

Medical Technology Q&A

Rob Phillips, managing director of professional battery manufacturer Accutronics, has identified several key trends that are emerging in the MedTech sector, from rising energy densities to new innovations such as wireless charging. Below he offers his insights into these trends, where he predicts to see the most market growth in the next twelve months and where Accutronics fits into the industry.

Who are you and what do you do? 
I'm Rob Phillips, managing director of Accutronics Ltd. Accutronics is a successful independent battery business serving specialist OEM’s in the Medical Device market and similar sectors, specialising in developing and manufacturing high-performance smart battery & charger systems.
We have an excellent portfolio of demanding OEM customers, who enjoy a real competitive advantage from their long-term partnerships with us.

As well as the medical and healthcare sector, our smart batteries are used in defence and security, as well as industrial test and instrumentation sectors. From small credit-card sized batteries for use in wearable medical devices to intelligent power vaults for use in high-power, high-discharge environments in hospitals, we make them all.

Some of our technical achievements include class leading protection circuits that prevent batteries from over charging, over discharging and overheating, as well as algorithmic security that prevents fake batteries from being used in life-critical medical applications.


How would you sum up your company?
Accutronics enables forward-thinking MedTech companies to create and deliver the next generation of portable medical devices.

As a leading battery manufacturer, we're dedicated to helping overcome new challenges including the use of portable devices in extreme environments, as well as improved battery security aimed at eliminating counterfeits. To do this, we've brought together a passionate team of designers, engineers and market specialists to apply their expertise in creating the battery solutions of tomorrow.

Name a business achievement you are most proud of?
Having grown the company from a startup in 2009, during one of the worst recessions in history, Accutronics is now a first-choice partner for some of the world's leading MedTech OEMs. This is something we're really proud of.


What excites you about this industry?
The environment of constant innovation is enthralling. Knowing that all these efforts are aimed at improving people's lives and the quality of their health makes this a very rewarding industry to be in. On top of this, there are real opportunities open to smaller and medium-sized companies to play a significant role in this innovation.

We've identified several key trends in the MedTech sector: battery energy densities are rising, as more and more equipment is becoming mobile; security is a big concern, especially when it comes to counterfeit batteries; the demand for premium medical devices in the Asian MedTech sector is growing rapidly; new innovations such as fast and wireless charging are on the rise; and finally, the development of antimicrobial polymers and surfaces is providing an extra line of defence against superbugs.


Where do you predict industry growth will come from over the next 12 months?
The BRIC countries, Brazil, Russia, India and China, are widely recognised as being economies with the fastest growing infrastructure in areas such as health service assets, transportation and specifically portable medical devices, which will deliver increased flexibility and value to healthcare users. This is where we expect most of the growth to come from.


Which medical device do you wish you had invented and why?
The plastic syringe, as it's one of the most versatile products. It's more robust and lighter than glass. It's much cheaper to manufacture, there must have been millions manufactured already. Products like the plastic syringe offer a lot of scope for use in the field and are indispensable in places like Africa where the logistics of medical equipment can be very challenging.

Analogue infrastructure needn’t hold you back

Thanks to the digital revolution, technology in both our personal and professional lives is getting smaller and more powerful. For instance, new smart watches have more computing power than the Apollo moon landing space craft! The same applies to medical equipment; hospitals are replacing bulky analogue machines with more svelte, powerful devices. However, the march of digital technology through healthcare facilities is bound by the existing infrastructure, which was developed for analogue solutions, creating unique challenges for battery equipment.

At Accutronics we’re seeing an increase in demand from the medical sector for thinner batteries to be used in new or updated equipment. While advanced technology is a key driver for this, another reason is the fact that original equipment manufacturers (OEMs) have to design machines that fit into an analogue legacy system.

For instance, in new digital x-ray machines there is only 15mm of space for a battery – the space that was set aside for photographic slides in outdated apparatus. This is because hospitals need new devices to fit into the same space as the old ones. So, development of new technology is being shaped by the infrastructure that has been established for low-tech requirements.

In addition, hospital buildings themselves contribute to space saving needs. While there are modern hospital buildings in the UK, there are also those that were built as far back as the 1800s. Mobile devices and carts have to be designed with manoeuvrability around narrow corridors in mind. Therefore, the components inside modern devices are packed tightly together, leaving no room for large battery packs.

Retrofitting or retrospectively designing systems like this creates interesting challenges when it comes to providing a suitable battery to meet both size and power requirements. It’s frustrating enough when your smartphone battery can’t keep up with your usage, but in the healthcare field interrupted power supplies can cause serious problems.

This means that Accutronics often supplies batteries with very thin section walls, as little as 0.8mm, to allow as much space as possible for the cells. Currently, the size of a battery cell can’t be reduced by all that much without losing power, so in very tight spaces you end up having to compromise the capacity of the battery by using fewer cells.

The key to success is for OEMs to consider the battery earlier in the design process. That’s why Accutronics encourages early engagement for all of its clients. While our bespoke battery solutions can be tailored to almost any situation, the earlier in the design our teams can get involved, the easier it is to ensure optimum performance for requirements.

Accutronics works with its clients to create truly outstanding battery solutions, which provide tangible end user benefits such as low weight, minimal volume and ease of use. This is often achieved via our custom battery and charger design and manufacturing service, Accupro, which integrates seamlessly into OEM device development programmes. Some of our batteries even have more advanced control systems than the Apollo 11, which was about as complex as a modern toaster. It's just our way of staying ahead of the curve!

Going for growth - New chairman to accelerate business development

International battery manufacturer Accutronics has appointed Steve Lamb as its new chairman. The addition to the management team will allow the company's managing director, Rob Phillips, to focus his efforts on new business development.

The new chairman will have a general management focus, working alongside managing director Rob Phillips, operations director Mike Allen and financial director Debbie Hodgetts. Prior to joining the Accutronics board of directors, Lamb built up a highly credible reputation as MD, CEO and chairman of a number of other companies, and brings with him an extensive amount of knowledge and expertise.

Lamb began his career in manufacturing before moving into the IT sector with the advent of 3D CAD/CAM systems in the early 1980s. His previous senior roles and directorships have included positions at software development business ECS, GADC Networks and on the International Executive Committee of listed European firm GFI Informatique.

"Our primary objective in appointing Steve is to bring a new dimension to our new business work," explained Accutronics managing director Rob Phillips.

"Among his responsibilities, Steve will chair the monthly management board-meetings, and once Steve is on board I’ll have more time to focus on sales and marketing."

"The original equipment manufacturers (OEMs) we work with as customer are chosen to match our capabilities as a potential strategic supplier," continued Phillips. "With the support of Steve and the rest of the management team we can strike a better balance between managing the company and growing the business. Our aim is to successfully enter new markets and expand our customer base."

The next-generation of portable power - Inspired Energy boosts the capacity of its standard smart batteries

The industry demand for longer running, smaller and lighter handheld equipment has prompted USA based battery manufacturer Inspired Energy to launch the HD34 range of high capacity Lithium-ion (Li-ion) smart batteries. These batteries use the latest innovations in cell technology to offer outstanding volumetric and gravimetric energy density resulting in longer run-times.

The batteries use the latest Lithium-ion cells with an increased capacity of 3.4Ah to provide customers with a longer runtime.

“The batteries use '18650' cells, which are the workhorses of the rechargeable battery world," explained Neil Oliver, technical marketing manager at Accutronics, the sole distributor for Inspired Energy. “Over the last 25 years Lithium-ion technology has improved and the capacity has steadily increased threefold, resulting in the latest high capacity 3.4Ah version."

Batteries using the 3.4Ah cells are available in two, three, four, six and eight cell configurations covering 7.2V, 10.8V and 14.4V outputs, so original equipment manufacturers (OEMs) developing new products can be confident in finding a platform that meets their mechanical and electrical requirements.

A wide variety of applications make use of the Inspired Energy batteries, including portable laboratory equipment and medical patient monitoring devices, hand-held data terminals, unmanned underwater vehicles, professional and broadcast cameras and satellite communication.

Lithium-ion batteries must be transported as dangerous goods, requiring batteries to be subjected to testing. The companies offering such products for transport are subject to strict packaging, labelling and paperwork requirements. Shipping of Inspired Energy Lithium-ion smart batteries is made easier as they have already been tested for transport and all have an energy density under 100Wh reducing the level of paperwork and packaging.

The new 3.4Ah cells allow batteries and devices to be made smaller and lighter. Some of the older battery models in the range use twelve 2.2Ah cells to provide 95Wh. When using 3.4Ah cells it is possible to realise this energy with just eight cells. This means the batteries can be made around 30% smaller and lighter, a real benefit to OEMs looking to reduce the size and weight of their devices, while still providing maximum runtime to users.

Inspired Energy standard smart batteries can be customised to meet the need of the customer, including changing the artwork to carry own-brand labels and modifying the smart battery data. Accutronics designs and manufactures its own range of batteries and chargers, but is also the sole distributor of the Inspired Energy range of standard batteries, chargers and accessories.

Having worked with Inspired Energy for over 20 years, Accutronics offers multi-currency pricing, online purchasing, European stock holding and fast customer support from its headquarters in the UK. Accutronics technical support service ensures that customers can design an Inspired Energy battery into their new device with total confidence. 

The credit card battery goes mini - Battery specialist launches its smallest ever, sub credit-card sized, battery

Global battery manufacturer Accutronics has launched its smallest ever medical battery and charger set. The CC1150 mini credit card battery meets the trend in the medical and instrumentation sectors for the growing use of portable and handheld devices.

Having already built a reputation for delivering the latest in smart battery technology for the medical sector, Accutronics' new mini credit-card battery, the CC1150, occupies around half the footprint of a conventional credit card. Measuring in at 54mm square and 9.5mm high, it fits perfectly into smaller, handheld, devices with ease.

Featuring a state of the art impedance tracking fuel gauge, the CC1150 is equipped with an I²C interface, simplifying its integration into the device. Enhanced circuitry provides further protection against over charge, over discharge, over current and short circuit.

"OEMs making handheld devices will be pleased to hear that, with the CC1150 mini, we've not only halved the size of the standard credit card battery, but we've also packed it with the same powerful features as its predecessor," explained Neil Oliver, technical marketing manager at Accutronics. "At the same time, we've still met the vital IEC 62133 safety requirements for batteries manufactured for use in portable applications, as well as UN38.3 transportation regulations.

"To make it a truly global battery, we've accompanied the CC1150 with a new charger, the CX3050, which works anywhere in the world thanks to its AC power adapter and interchangeable blades. For portable and handheld devices, fast charging is just as important as long battery life, so we designed the CX3050 to charge the CC1150 in under 2.5 hours," concluded Oliver.

Both the battery and the CX3050 charger are available off-the-shelf in black and feature Entellion branding. Users can request custom colours, labels and packaging.

Launched in 2011, Accutronics' range of credit card batteries are targeted to meet the needs of medical and instrumentation original equipment manufacturers (OEMs) who need a small, off-the-shelf, Lithium-ion smart battery.

Four years after development, the credit-card range of batteries are now used widely in applications ranging from industrial laser measurement devices to medical infusion pumps. Other innovations such as desktop charging have given users the flexibility to charge batteries outside of their devices.

Charging ahead in innovation

~Accutronics celebrates a year of innovation at America's largest medical technology show~

Smart batteries for medical devices

International battery manufacturer Accutronics will join thousands of medical industry suppliers and
service providers at MD&M West, on February 10-12, 2015 in Anaheim, California, where the British company will showcase the latest products from its Entellion range. Accutronics can be found in Hall E at Booth 412.

The theme of the 2015 conference is a celebration of 30 years of medtech innovation, and this year British manufacturer Accutronics has proven it is more than up for the challenge. During 2014, the independent battery expert launched two new products to add to its range of smart portable power products, both of which will be exhibited at the event.

Most recently, Accutronics introduced the CMX Series, a range of innovative smart batteries and chargers. With the increase in the use of portable medical devices, such as acute ventilators and anaesthesia workstations, the new smart battery fulfils the needs of manufacturers of high powered medical devices.

During the summer the company also introduced the CX6100, an innovative desktop charger for its groundbreaking credit card battery range. The new charger has a rapid charge capability and can be used around the world, thanks to its wall mounted power supply. The credit card battery range provides OEMs with a rechargeable range of Lithium Ion professional batteries for portable and wearable medical devices.

"The medical market is a challenging environment and there's a constant demand on medical OEMs to produce innovative portable devices," explained Rob Phillips, managing director of Accutronics.

"Thanks to our understanding of the market requirements we've been able to develop a range that meets the need for high energy density and high power discharge, without compromising on safety and reliability in life-critical applications."

At the event, the Accutronics team will showcase its skills in the design, development and manufacturing of medical batteries and smart chargers. On display will be the complete Entellion range of products which bridge the gap between standard off-the-shelf products and a custom design with inherent development fees, saving customers time and money. The range can easily be customised with options including product labelling and case colours, software setup and SHA-1 algorithmic security, which prevents counterfeit batteries being used under fraudulent warranty claims.

Going global

Accutronics is a UK developer and manufacturer of custom rechargeable batteries for professional applications. The business runs a global operation from its HQ and manufacturing facility, near to the city of Stoke-on-Trent in the West Midlands. Set up in September 2009, Accutronics has around 80 employees and its battery products are exported to over 30 countries across Europe, North America, Africa and the Middle East. Rob Phillips, managing director of Accutronics, offers advice to companies considering exportation.

Rob Phillips discusses custom rechargeable batteries at Compamed

Exporting enables us to reach the majority of our potential customers, the vast majority of whom are not based in the UK, rather than limiting our business to our own backyard. We target specific product application market sectors, such as Original Equipment Manufacturers (OEMs) of portable medical devices, chosen to match our capabilities as a potential strategic supplier. We then research who these companies are and where they are based.

For any business considering exporting, my advice is to think big and look into it properly and personally. The worst that can happen is that you end up with a wiser, wider perspective on your business sector and decide in a well-informed way not to proceed. More likely, you will open up much greater potential growth for your business.

Carry out desk research, but then travel and investigate your potential future markets directly. Industry events, such as conferences and exhibitions, are a great opportunity for further research.

In November we exhibited at Compamed in Dusseldorf, Germany, a leading trade fair for the medical industry which hosts 700 exhibitors from 40 countries, and runs alongside the huge Medica exhibition on the same trade fair site.

For UK firms active in the medical equipment market, the sheer size and scope of this event is in a different ball park to UK-based trade fairs. Quite simply it needs to be experienced to be believed. I'd suggest attending an event like this and assessing whether you want to invest in an exhibition booth next time.

Depending on your sector, there may be some potential barriers, but if you have a good product or service that you believe in, then in our experience buyers are very interested in giving you a chance, regardless of your HQ location. In our industry sector, we successfully export to over 30 countries without using agents, distributors or any other export partners. Today, export makes up 95% of Accutronics’ sales turnover.

Charging ahead with medical devices

~ Hi-tech medical equipment goes portable with new energy-dense battery ~

Independent battery design, development and manufacturing expert Accutronics has launched a new smart battery that fulfils the needs of manufacturers of high powered medical devices. The CMX series packs a punch - offering high energy density along with high power discharge. Medical OEMs (Original Equipment Manufacturers) can now produce innovative portable devices without compromising on safety and reliability in life-critical applications.

The medical market is a challenging environment, and understandably so. With people's lives on the line it is essential that medical practitioners can rely on their equipment to perform under pressure. The rise in the use of portable devices such as acute ventilators, anaesthesia workstations and intra-oral scanners over the last twelve months has left many medical OEMs struggling to keep pace in the market.

“Part of our branded Entellion range, the CMX meets stringent regulations, demanding development schedules and innovation aims, whilst minimising unit costs," explained Neil Oliver, technical marketing manager at Accutronics.

The battery is available in three versions, using eight, twelve or sixteen '18650' sized cells, with continuous discharge rates of up to 300W. Two voltage platforms are used; 28.8V, which operates between 20.0V and 33.6V and 14.4V, which operates between 10.0V and 16.8V.

Smart features of the CMX series include active and passive protection circuits that prevent over-temperature, over and under-voltage, overload and short circuit.

Forming an essential part of its medical device operation, smart power management means the battery only requests charge when needed and shuts down when not being used. Accurate fuel gauging is possible to 1% through an LCD display, further enhancing reliability.

The new battery complies with the relevant transport regulation, which exists to eliminate the risk of explosion associated with the transport of such energy dense cargo. The CMX series complies with transportation (UN 38.3) and safety (UL2054 2nd ed. and IEC61233:2012) as well as electromagnetic compatibility (EMC) regulations (CE and FCC).

The range charges between zero and +40 degrees, discharges between -10 and +50 degrees and can be stored between -20 and +60 degrees. This results in 500 cycles of 80% minimum rated capacity.

Hospitals can now perform routine power management checks without having to remove the medical device from service using the smart charger that accompanies the CMX battery. A single charger can be used for different sized batteries, because the two devices automatically communicate exact voltage requirements.

For customer convenience, two chargers are available to accompany the CMX series, an internal single channel charger and an external dual bay desktop charger, which can also be used for battery calibration.

Whether batteries or chargers, the Entellion range is made to be customised. Options include product labelling and case colours, software setup and SHA-1 algorithmic security, which prevents counterfeit batteries being used under fraudulent warranty claims.

Trust me, I'm a medical device

There is a growing debate surrounding the rise in mobile medical devices. The concern is that the increased reliance on electronic devices to monitor and treat our health becomes dangerous if those very devices become unsafe or unreliable to use. Here, we explore the security and safety of batteries used in our critical medical equipment going forward. 

Medical devices are moving from the once fixed sanctuaries of hospital wards and wandering out into our portable world. The abundance of WiFi, the interconnectivity of electronics and remote information exchange has given rise to the increased portability of the critical devices that monitor our health and provide doctors and paramedics with the tools necessary in delivering flexible and customisable treatment.

However, this rise in portability has created numerous security challenges. The US Food and Drug Administration (FDA) last month pushed for improved cyber security when it issued guidelines aimed at helping medical device manufacturers manage cyber security risks as well as "maintain medical device functionality and safety".

The guidelines will decrease the number of incidents of medical devices being hacked, putting the life of patients in jeopardy. Controversies, such as the one reported by former US Vice President Dick Cheney who, fearing assassination, told doctors to turn off the wireless functionality of his pacemaker after it was found that it could be wirelessly hacked, will be avoided.

However, the problem of security is not limited to the wireless capability of devices. A lack of hardware based encryption has already caused widespread concern over the reliability of batteries used in such equipment.

The fact that portable medical devices have to be designed to operate without mains electricity/AC power access necessitates the use of reliable and safe backup-power management systems. Devices such as acute ventilators, portable anaesthesia workstations and intra-oral scanners all need continuous and safe power to protect patient health.

Battery counterfeiting is a problem faced by the medical industry on a scale never before witnessed in the sector. The ready availability of grey market, untested copycat batteries using inferior components means that many life-critical devices used in our hospitals and medical establishments are becoming unreliable and unsafe to use.

Here at Accutronics, we've worked hard to tackle this problem and will be launching a new CMX series of smart batteries and chargers this November. The new range incorporates some innovative features that include SHA-1 hardware encryption, to prevent fake batteries being used with the host device, active and passive protection circuits, accurate fuel gauging, smart charge control and device-to-host communication.

The new batteries can be transported, stored and used safely, without overcharging, over discharging, overloading and short-circuiting. Thermal sensing on the battery triggers alarms if it is too hot; removing it from the circuit if the operating temperature exceeds safe levels.

Smart power management is what makes the CMX range stand out. Whereas other dumb systems that use a fixed-voltage cut off to prevent over-discharge, the intelligent system in the CMX maximises runtime per discharge cycle by telling the host device when to shut down based on highly accurate remaining-capacity prediction.

Visitors to COMPAMED can find out more about how the CMX range will revolutionise the mobile medical market at Accutronics' product launch press conference. The event will be held at 3pm on the 12th of November, 2014 in room 801a off hall 8b at COMPAMED. If you're interested in attending, you can register for free by calling 01785 225416 today.

If you’re unable to make it to Compamed we will also be launching and displaying the new CMX series at ELECTRONICA in Munich between 11th & 14th November in Hall B2 Stand Booth 454.

High-five for high-power

Tackling the rise in demand for portable medical devices delivering high-rate power discharge, battery specialist Accutronics will be launching a new CMX range on 12 November, 2014 at COMPAMED, the international medical trade show held in Dusseldorf, Germany. In anticipation of the launch, we explore the world of portable power.

Speed is of the essence in life-critical applications. Usually, ambulance crews will transport heart-attack patients to the hospital's emergency ward as soon as possible. However, a leading UK Accident & Emergency doctor recently called for patients to be treated by paramedics until their heart starts beating or they die.

Writing in the British Medical Journal, Dr Benger says that it, "may be actively harmful" to rush cardiac arrest patients to hospital. Because there is only a short time-window of around 50 minutes before permanent brain damage sets in, it is vital that treatment is provided quickly and effectively.

The last few years have seen an increased demand in mobile technology used in hospitals and in the field. Specialised stroke emergency mobile (STEMO) ambulances fitted with portable CT scanners cut the alarm-to-treatment period to just 25 minutes. Acute ventilators, portable anaesthesia workstations and intra-oral scanners are other examples of medical equipment breaking free from the traditional mains power supply.

However, the challenge with these devices is the high-rate power delivery required to operate reliably. The recent Ebola outbreak in West Africa has highlighted the challenge of transporting patients from one part of the world to another. Medical equipment used in the transport of patients must be capable of operating with limited resource for electricity, water and compressed gas.

On September 4, 2014, in response to the Ebola outbreak, the World Health Organisation (WHO) issued guidelines for medical equipment donated for use in the field. The guidelines reinforce the necessity for devices to use high-quality backup power, with current stabilisation, surge protection and uninterrupted power supplies to protect against blackouts and unsustainable mains power.

To overcome these problems, here at Accutronics we've developed a new CMX smart-battery range specifically for high-power applications. Capable of accurate fuel gauging, built to international regulatory standards (IEC62133, UL2054) and offering device-to-host communication for continuous swappable power, the new range will be especially useful in the increasingly dynamic nature of modern hospital care.

Visitors to COMPAMED can find out more about how the CMX range will revolutionise the mobile medical market at Accutronics' product launch press conference. The event will be held at 3pm on the 12th of November, 2014 in room 801a off hall 8b at COMPAMED. Alternatively you can view and discuss the new product range in Hall 8b Stand F30 where Accutronics will be exhibiting. If you're interested in attending, you can register for free by calling 01785 225416 today.

If you’re unable to make it to COMPAMED, we will also be launching and displaying the new CMX series at ELECTRONICA in Munich between 11th and 14th November in Hall B2 Stand Booth 454.

A designer's headache

At the end of March, Sataya Nadella the new CEO of Microsoft gave his first keynote speech only 52 days into his new role. Speaking at the company’s Cloud conference, also dubbed the ‘Office for iPad’ event, he expressed Microsoft’s vision for mobile and cloud computing moving forward. Here, Neil Oliver of Accutronics considers the implications of advancing consumer technology for designers of medical devices that rely on battery size reduction.

It was a bold but necessary step. Microsoft’s ethos of traditional fixed-unit computing has struggled to compete in recent years with the sheer intensity of competition offered up by the likes of Apple, Samsung and Google. Rapid innovation of powerful mobile operating systems, that offer more portable productivity solutions, has left the software giant reeling.

The trend towards mobile devices is nothing new. Having experienced a seismic shift, the industry has gained momentum in cycles over the last twenty years. We have now reached a point where mobile users outnumber desktops, laptops and Internet users, combined.

However, there are drawbacks to such fast paced innovation. The traditionally linear product development has morphed into a vicious cycle of ever increasing consumer expectations, in conjunction with an increased competition to reduce the time to market for each device-iteration.

This has left designer’s scratching their heads. Design objectives that seemed impossible to implement only a few years ago, are now the norm. As a result, user expectations are getting higher and higher. As customers we want bigger screen sizes, with higher resolutions, packed into thinner, more lightweight devices, with lower price points and long run times.

This is as true in the world of professional batteries for medical devices as it is the consumer environment.

In a typical product development lifecycle, industrial and product design consultants are drafted in at the concept stages. The consultants usually specialise in areas such as ergonomics, electronics or even manufacturing readiness. The power solution, in the form of the battery design, is often an afterthought in this process.

Because ergonomics and manufacturing have taken a front and centre seat in meeting consumer requirements, the consultants brought in, don’t always have the most up to date skills in battery technology. It is for this reason that, whilst device design has moved forward, design engineers often struggle to meet the ever tightening requirements for batteries.

However, by relegating the battery solution to an afterthought we risk limiting the options available to designers, making a battery that is truly fit for purpose less likely. By limiting the volume, thickness, weight and material availability, Original Equipment Manufacturers (OEMs) may have to compromise in other areas. These variables can directly influence factors such as cell selection, robustness, runtime, efficient operating temperatures, reliability and total life.

Not considering these issues at the design stage could spell disaster in the long term.

The first consequence is as a result of shaving millimetres off the device and thus battery size. For instance, single-cell Lithium-ion batteries in consumer devices such as phones and tablets are being encased in increasingly thinner packaging. This means that accidentally dropping your phone could rupture the battery casing, causing a short circuit. Although extremely unlikely, this could cause the battery to heat up and even explode.

Although an extreme example, a more likely consequence in a medical device would be an inefficient discharge rate at low operating temperatures. Medical devices used outdoors by rescue teams are a prime example. Whilst OEMs seek to market their devices as capable of operating from -20 to +60 degrees Celsius, designers struggle to optimise batteries to perform effectively at both extremes.

For example, a battery optimised for low temperature discharge, will struggle to maintain efficiency in high temperatures, and vice versa. This also means that accurate fuel gauging becomes difficult; creating a potentially hazardous problem for medical and life-critical devices.

Another challenge is device weight. The consequence of pursuing the thinnest and lightest device is that OEMs ultimately compromise on run-time and battery lifetime.

A battery’s energy density is directly proportional to its volume and mass. By reducing the weight of the battery, and subsequently its energy, the runtime is lowered. Even Lithium-ion batteries, which offer the highest energy density commercially available, will struggle to cater for customer expectations in this environment.

Here at Accutronics, we’ve found that the easiest solution to overcome these problems is to work with OEMs at the concept stages to build in requirements for reliable and robust battery design. This helps to achieve a good balance between innovative design and battery performance. It’s a process that market leaders like Microsoft would surely applaud, particularly given Nadella’s focus on mobile first.

Battery firm makes excellence a habit

~ Accutronics receives ISO 13845: 2003 quality standard ~ 

In February, international battery manufacturer Accutronics was awarded the ISO 13845: 2003 quality standard. The company received the accreditation for the design, manufacturing and testing of battery products and battery chargers for medical devices. 

ISO 13485:2003 is underpinned by the ISO9001 quality standard, which Accutronics has had in place for several years. However, it is significantly more specialised and dedicated to the medical device manufacturing sector.

The new standard specifies requirements for a quality management system in which manufacturers have to demonstrate the provision of medical components that satisfy customer and regulatory requirements.

ISO 13485:2003 details additional commitment to continual improvement, above and beyond the requirements of ISO 9001. The major differences are the design and traceability procedures as well as an additional focus on supplier audits.

“We’ve been working tirelessly to develop new and improved batteries for medical devices that help save lives in hospitals across the globe,” explained Matt Simcock, quality manager at Accutronics. “However, for some of the OEMs we work with, this stamp of approval is essential for building trust.

“This caused us to start working towards ISO 13845: 2003 twelve months ago. It was new to us in the beginning, but thanks to the strong and supportive team we have here, we achieved the accreditation in a very short period of time.

“As quality manager I had the task of creating procedures for the design and manufacturing teams and looking at traceability and sustainability issues. The end result is remarkable and I couldn’t be happier,” he enthused.

“Gaining the ISO 13845: 2003 stamp for the quality of our designs, manufacturing and testing procedures was a huge boost for everyone in the company,” said Rob Phillips managing director of Accutronics. “The new procedures and internal audits have made us a leaner manufacturer and we’re starting to see the results on the bottom line. What’s more, we are now in an even better position during tenders and sales meetings,” he concluded.
