Designing Safe and Reliable Medical Devices with WPG and ATS

Thermal management is important in all electronics, but the thermal management of medical electronics is especially important as it deals with the health of all of us and our families. WPG Americas Inc., along with Advanced Thermal Solutions, Inc. (ATS) and other manufacturers, has released an eBook designed to provide helpful information for the proper power design for those systems.

WPG Americas Inc., ATS, and other companies joined together to create this
Medical Device eBook for Engineers. (WPG Americas Inc.)

The eBook discusses the main principles of IEC 60601-1 and how they apply to power supply design. It also looks at the evolution of the standard through to the fourth edition and provide an overview of medically-safe power solutions available for medical equipment designers and manufacturers.

Finally, the book touches on solutions in the medical device design space by leading manufacturers like Cosel, NMB and Advanced Thermal Solutions.

At ATS, we work with engineers to design thermal management solutions optimized for a variety of applications, including Medical Diagnostic, Biomedical, and Gene Sequencing Equipment.

Below are some of the products we’ve used for this engineering work:

Products Used in
Medical Applications
Application Notes
Heat PipesOften used to draw heat away from a high-power area, such
as from an image processor to a
medical device chassis.
TLC-100 and tvLYT™Less expensive than an IR camera
or other options, these instruments
give engineers reliable liquid
crystal surface thermography to
visualize hot spots on
semiconductors or other parts of a PCB.
Push Pin Heat SinksUsed when a very secure
attachment is needed, such as in
applications with consistent shock
and vibration concerns.
Cold PlatesOften used as part of a liquid loop
in larger medical diagnostic
equipment for high-power
applications such genome
sequencing, imaging, or
tissue thermal management.
Candlestick Sensor and Hot Wire
For measuring air temperature and air velocity at one point, with the
same sensor. Ensures that a system design has the right level of
airflow to ensure safe and proper
Pin Fin Heat SinksThese are inexpensive heat sinks
with good thermal performance
that accommodate multi-
directional air flow.
Power Brick Heat Sinks Used most commonly in the power supply of the system for cooling DC-DC power bricks.
Heat ExchangersOften used as part of a liquid loop
in larger medical diagnostic
equipment. For high-power
applications such as genome
sequencing, imaging, or
tissue thermal management.
fanSINK Heat Sinks with maxiGRIPUsed for medical applications that have limited airflow where direct airflow is required.
Extrusion Profile Heat SinksThese are often used in custom
medical equipment applications
when an engineer wants to
experiment with a variety of fin
fields, lengths and base thicknesses.

ATS holding webinar on Thermal Management of Medical Electronics

Medical Webinar

DR. Kaveh Azar, founder, CEO and President of Advanced Thermal Solutions, Inc. (ATS), will present a free webinar on “Thermal Management in Medical Electronics” on Dec. 15, 2016.

On Thursday, Jan. 26, Advanced Thermal Solutions, Inc. (ATS) will host a free, online webinar on “Thermal Management of Medical Electronics”. The hour-long webinar will begin at 2:00 p.m. and there will be 30 minutes of question and answer time after its completion.

The webinar will be presented by thermal management expert Dr. Kaveh Azar, the CEO, President and founder of ATS. Dr. Azar will speak about the unique challenges that are present in finding a thermal solution for medical electronics and the importance of including thermal management in the design process.

The object of all thermal management is to ensure that the device junction temperature, the hottest point on a semiconductor, stays below a set limit. While this is true for all electronic systems, medical electronics pose unique thermal challenges that have to be overcome to meet the junction temperature requirements.

Medical electronics could have stringent material selection. For example, copper is a common metal chosen in thermal management, but can cause irritation or a neurodegenerative condition for patients and has to be used carefully. In addition, medical electronics may have spatial constraints, such as forceps that have only 2-4 millimeters of width, which is a constrained space with very little airflow.

Other challenges presented by medical electronics include the need for constant, reliable repeatability; temperature reliability within a range; and in some cases specific FDA requirements.

Dr. Azar will address each of these issues and more. To register for the free webinar on Thursday, Jan. 26, visit http://www.qats.com/Training/Webinars.

Thermal Management of Medical Equipment is not just about keeping it cool; it might mean life or death for the patient

Yesterday we noted Thermacore’s new white paper, “Thermal Management for Today’s Medical Devices and Equipment“. As we noted yesterday, we couldn’t agree more with Thermacore’s premise. Here at ATS, our team thinks the topic of proper thermal management of medical equipment is vitally important to people’s lives. So important, we wanted to post a bit more about it.

Key trends we are seeing in thermal development in the medical industry:

  • Unquestioned Reliability
  • Instruments with greater accuracy and capability
  • Reduced size and miniaturization

Reliability is important on at least two levels. First, if the equipment is not reliable, the economic payback simply won’t be there for a physician, clinic or hospital. For example, CT scanner’s can cost up to $300,000. If it’s unreliable due to thermal stress, the payback investment might be twice as long as what would generally be seen.

The second reason for reliability is for patient and doctor confidence. Patients want to have confidence in the equipment they are being tested on. This can reduce their personal stress by trusting the results they will receive are accurate. Doctor’s want to be confident in the diagnostic equipment they are using. Doctor’s want to trust the data they get is accurate enough for them to determine a diagnosis.

The accuracy and diagnostic capability is important too. For any medical equipment to be useful the data collected has to be accurate or else a wrong diagnosis might occur.
The fallout from that reduced accuracy can be devastating as incorrect diagnosis may be formed leading to an incorrect course of healing for the patient. Poor thermal management of key components and entire systems can cause processors within the medical equpiment to overheat, slowdown and potentially return data errors.

Finally, reduced size and miniaturization can mean diagnostic equipment gets deployed more widely increasing it’s potential use and benefitting the health of the population where it is used. The packaging for this smaller equipment requires careful attention to the thermal design. Regardless of how low power the components used, the smaller the space, the more the airflow will be reduced and the increased likelihood for thermal stress and component malfunction.

Thermal management of electronics is critical to their functioning properly and being a tool that helps people’s health. At ATS, we have developed thermal management solutions, including heat sinks, for a variety of medical applications from EKG machines, to Defibrillators, to Ultrasound equipment and Tissue/DNA Analyzation instruments.
