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.
