Thermal Management for Medical Devices

Thermal Management for Medical Devices

Electronic Medical Devices thermal management needs are similar to those in other industries and are subject to the same technological advancements calling for more compact designs with faster processing requirements. Medical Devices need to be able to run continuously within in their safe operating temperature ranges as overheating could lead to incorrect data, compromised performance or even shut down. Effective thermal management enables excess heat to be dissipated from components which provides optimal system reliability and increased lifespan of the device.

Importance of Thermal Management for Medical Devices:

Device Performance and Longevity: Heat is a natural byproduct of electronic components’ operation. Excessive heat can degrade the performance of devices and shorten their lifespan. Maintaining an optimal operating temperature is essential for ensuring that these devices function reliably over an extended period.

Energy Efficiency: Heat generation can lead to increased energy consumption, reducing the energy efficiency of the device. Proper thermal management can help minimise heat-related power losses, ensuring that devices operate more efficiently and consume less power.

Data Accuracy: Many devices rely on sensors and transmitters that are sensitive to temperature changes. Elevated temperatures can cause inaccuracies in the data collected by these sensors, impacting the quality and reliability of medical systems.

User Safety: In cases where devices are deployed in sensitive environments, such as medical implants or wearable devices, excessive heat can pose safety risks. Overheating devices may malfunction or even become hazardous.

Surgical Instruments:

Thermal management for surgical devices is critical for patient and surgeon safety. Devices and instruments need effective thermal management to ensure safe continual operation and handling of instruments in theatres. Cauterising forceps are used to burn away unwanted tissue and cells or to close wounds during surgery, studies show that if the temperature of the forceps exceeds 80°C the tissue sticks to the forceps during procedures, to avoid this happening Heat Pipes are placed in the tip of the cauterising instrument for active heat transfer to ensure the device does not exceed its safe operating temperature.

Medical Screening

Screening and Sampling:

Screening assays including High Throughput Screening (HTS) Polymerase Chain Reaction (PCR) cycling technology and sampling require robust thermal management for continual operation and data accuracy. HTS is primarily used in drug discovery where large volumes of data can be processed and modelled in a relatively short time frame thanks to the application of robotics, sensors and machine learning to enable researchers to develop more efficient and cost effective discovery programmes these systems will require a range of Thermal Interface Materials (TIMS) and products for their electronics cooling. PCR cycling device thermal management may use Thermoelectric Cooling Chips (TECs) and Vapour Chambers for heat dissipation. Biospecimen sampling often uses silicone sensitive lasers and optronics for calibration and measurement of thousands of samples each day and will need to be protected from overheating not only from the high throughput of their components using silicone free TIMs but also the heat generated from mechanical parts such as conveyors and continuous power consumption.

Imaging and Optronics:

Many modern medical devices utilise advanced optronic technologies and microprocessors for digital imaging, lasers and ultrasounds. These optoelectronic application lenses are sensitive to silicone, therefore choosing the right thermal interface material is vital to ensure long term reliability of optronic devices and components. T-Global Technology has a range of Non-Silicone Thermal Pads, Putties and Tapes to ensure performance reliability from silicone sensitive applications. For high power devices with multiple heat sources such as MRI, CT and X-Ray machines, temperature fluctuations can affect calibration and results and thermal modules comprising of Heat Sinks, Heat Pipes, Vapour Chambers and TIMs will need to be used to dissipate heat from the device to the environment.

Wearable Devices and Implants:

Wearable devices and implants cover a range of products including insulin monitors and pumps, ECGs and hearing aids through to pacemakers, biosensors and prosthetics.  Heat is generated during operation from processing sensor data. Effective thermal management is crucial to prevent discomfort for users and to maintain device performance to ensure accurate data reporting. Thermal management of wearable devices is especially challenging because of their small sizes and high power consumption. T68 Synthetic Graphite Sheets are commonly used in wearable devices thanks to their excellent thermal conductivity  (1500 W/mK) and ultra thin size. Pacemakers and defibrillators are small devices with limited space available for heat dissipation. These devices contain electrical components such as transistors and integrated circuits, which generate heat. The close proximity of medical implants within the human body poses a risk of thermal injury and malfunctions if the devices overheat. To address these high-risk challenges, a reliable solution that can guarantee successful thermal management becomes imperative, TG-A09AB is a thermally conductive silicone potting compound used to protect electronics from moisture and can be used in implanted devices.
