Revolutionising medical device design: the role of advanced thermal solutions
Original Equipment Manufacturers (OEMs) are increasingly seeking out sophisticated thermal solutions to improve the performance of medical devices. With over 2 million different medical devices across the global market, according to WHO, the design of these critical devices must be perfect. In this article, Andy Selvy, chief systems designer at industrial heating technology manufacturer Watlow, delves into the transition from traditional heaters to advanced, layered heater technologies in medical device design.
The critical role of thermal management in medical devices Thermal management within medical devices, clinical diagnostics instruments and analytical instruments involves the sophisticated control of temperatures to prevent overheating and ensure devices operate within their optimal performance range. Proper thermal regulation is vital because even the slightest of deviations can lead to device failure, diminished treatment effectiveness, or serious risks to user safety.
Effective thermal management is crucial for devices that generate significant heat during operation or that use heat as part of therapeutic treatments. Examples include maintaining body-temperature fluids in dialysis machines and regulating the temperature of surgical tools to avoid tissue damage. This precise temperature control is essential for the success of treatments and the safety of patients.
Addressing the challenges
The introduction of sophisticated heating technologies into medical devices brings a set of complex challenges that must be carefully managed. Advanced heating solutions must not only provide effective temperature control but also ensure safety, requiring rigorous testing and adherence to international safety standards such as IEC 60601-1-11. This regulatory standard outlines specific safety requirements for medical electrical equipment.

Temperature-stable small OLED displays for extreme applications
DISPLAY VISIONS has launched a series of durable white and yellow small format OLED displays for use in extreme temperatures. As self-illuminating, they are exceptionally flat and high-contrast in all directions. They are available with pins for direct mounting or with ZIFF connections. Whether it is Arctic cold or tropical heat, the durable, small format OLED displays from DISPLAY VISIONS can cope with the most extreme ambient temperatures. They work reliably in a wide range of temperatures from -40° to +80°C. Even at -40°C, the typical response time remains an ultra-fast 10 µs without afterglow. This makes this graphic OLED range ideal for use in refrigeration or cold storage facilities. They also perform their duties reliably and for a long period of time in hand-held devices for outdoor use or in drying kilns, saunas or machine rooms. With their self-illuminating OLED technology, these panels do not require backlighting. They are therefore very flat, having a thickness of between 2 and 2.5 mm. These devices do not suffer from temperature-dependent contrast drift.
