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.
Achieving high thermal efficiency is essential to prevent overheating, enhance energy efficiency and minimise operational costs. This involves optimising heat transfer capabilities, improving insulation and selecting materials that exhibit excellent thermal properties. Each of these factors plays a critical role in the development of safe and effective medical devices.
Furthermore, the development of cutting-edge thermal solutions can be both complex and costly. Manufacturers must balance these factors with the need to produce affordable medical devices. This balance is crucial to ensure that advanced medical technologies remain accessible to healthcare providers and patients alike. Balancing cost and complexity requires innovative design strategies, efficient manufacturing processes and careful material selection to ensure the final product is both effective and economically viable for the market.

METCASE’s New Universal Carry Handles For Portable Electronic Enclosures METCASE is raising the bar with a new range of universal tilt/swivel carry handles for fitting to any customer-specified metal electronic enclosures.
These ergonomic carry handles double as desk stands. They can be adjusted in 30° increments, enabling the device to be positioned at the perfect angle for viewing and operation.
Ordering the handle kit requires the customer to specify two parts. Firstly, there is a side arm kit which includes two diecast zinc side arms and location bosses (incorporating
the spring ratcheting mechanism), two snap-in moulded push-buttons, two anti-glide rubber rings (for stable positioning on the table-top) and the assembly screws. Fitting the side arms simply involves machining three holes on each side of the customer’s enclosure.
The side arm kits are offered in four standard colours: off-white (RAL 9002), anthracite (RAL 7016), light grey (RAL 7035) and black (RAL 9005). The push- buttons are supplied in a contrasting or matching colour.
Lastly, the customer just needs to specify the required length of extruded aluminium handle bar that fits between the two side arm assemblies. The dimension is simply the width of the customer’s enclosure (where the handle will be fitted) less 26 mm. METCASE will then supply the extrusion to the correct length. The handle bars are available painted in the same colours as the side arms and also in silver metallic (RAL 9006).
To order the handle bar, simply select the handle colour part number and replace the XXX at the end with the required dimension. For example: for a 350 mm wide customer enclosure, the machined bar length is 324 mm (350 mm less 26 mm). So, the part number will be M50930-324 with the bar painted in silver metallic (RAL 9006).
METCASE can supply these handle kits painted in alternative RAL colours. For special colours, the moulded push-buttons will be supplied in black (RAL 9005).
