Capacitive switches prove critical for medical monitors
Stadium IGT offers a range of single LED illuminated capacitive switch modules that are proving to be critical components to medical equipment manufacturers. Earlier this year Stadium IGT were approached by a leading medical OEM to provide a HMI solution for a new high-performance acute foetal and maternal intrapartum monitoring system.
Detecting pilot hypoxia in-flight & in real-time
United States researchers, led by the Air Force Research Laboratory, 711th Human Performance Wing, Wright-Patterson AFB, Ohio, replicated a fairly standard ‘hypoxic’ event. Volunteers were exposed to 5 minutes of reduced oxygen levels to simulate higher altitudes, followed by 5 minutes at 100% oxygen ‘recovery’. This is a typical response protocol to in-flight hypoxia.
Designing medical devices for EMC
The MedTech world, along with the wider healthcare industry, has experienced a trend for more portable and wearable devices in the last few years. The problem is that these devices require lighter and equally portable batteries and chargers that use SMPS, a technology that is prone to higher EMI - not a useful characteristic for devices intended for use in life critical medical environments.
Key trends emerging in the MedTech sector
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. 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.
Autoclavable mass flow meters in the spotlight at COMPAMED
Sensirion will be exhibiting at the COMPAMED 2015 trade fair, presenting its autoclavable mass flow meters, the SFM3200-AW and the SFM3300-AW, for the first time. The autoclavable and washable sensors boast high precision and robustness. They are suitable for measuring respiratory flows in medical applications such as artificial ventilation or anesthesia.
1W surface mount DC/DC converters certified for medical use
Murata has announced it has introduced the NXJ1, a series of single output, high reliability, high isolation, 1W surface-mount DC/DC converters designed for medical products, with other applications in industrial, transport and telecoms markets. Manufactured by Murata Power Solutions and measuring only 13.72x10.46x4.36mm, this compact low-profile series features six models comprising nominal input voltage options of 3.3, 5 or 12VDC and singl...
Micro control valve is whisper quiet
Bürkert Fluid Control Systems has recently launched its latest addition to the micro fluidics range, the Type 6712 WhisperValve, which is a plunger type design with media separation, that measures only 7mm wide and has a switching time of less than 5 milliseconds. Designed for medical applications such as dialysis, drug delivery systems and in-vitro diagnostic work as well as precision inkjet printing, this latest development from Bürke...
Medical sensing solutions showcased at Compamed 2015
At this year's COMPAMED trade fair, Sensirion will present its latest enhanced sensor solutions for measuring humidity and temperature, gas flow, liquid flow and differential pressure. The company will introduce two mass flow meters: the SFM3200-AW and SFM3300-AW. Both products are suitable for repeated, inter-patient use thanks to their multi-cycle, autoclavable and washable properties which allow them to be sterilised.
Scanner offers real-time 3D breast cancer screening
Scientists, working primarily at Florida International University, have developed a hand-held optical scanner with the potential to offer breast cancer imaging in real time. As reported today in the journal Biomedical Physics & Engineering Express, the device uses a near-infrared laser diode source to produce an image of the breast tissues.
Wearable cardiac recorder offers mobile peace of mind
A powerful STM32 microcontroller from STMicroelectronics keeps things ticking inside HTEC's wearable ECG recorder that provides continuous and accurate remote cardiac monitoring. Different types of cardiac arrhythmia, or irregular heartbeat, affect millions of people of all ages worldwide. With the accurate and timely diagnosis, causes of most arrhythmias are effectively treated, minimising fatalities.
