EMI gaskets are one of the unsung heroes powering medical devices that save lives. When reaching for life-saving medical equipment, we expect it to work. This, in part, is achieved with the help of EMI gaskets. Although they are small and never seen, gaskets serve several functions.
EMI Gaskets & Thermal Management
EMI gaskets help with thermal management. Electronic components in medical devices generate heat during operation, and this excessive heat can reduce the reliability and lifespan of these components. Additionally, localized hot spots can be a safety concern because of malfunctioning equipment. The scientific principle here is thermal conduction, where heat energy is transferred through the gasket material to a larger surface area, using materials with high thermal conductivity to spread and dissipate the heat.
Electromagnetic Compatibility (EMC) Engineering
Electromagnetic disturbances affect the device’s functionality and may lead to hazardous situations. EMI gaskets function by creating a conductive enclosure, ensuring the continuity of the shield around sensitive components. This continuity is critical to prevent “leakage” of EMI, which can interfere with the device in question and other nearby equipment. By creating an effective barrier, EMI gaskets help devices meet EMC standards, which specify the limits of electromagnetic emissions and immunity requirements.
What Happens without EMI Gaksets?
Because of inadequate protection, it is essential to recognize the importance of EMI gaskets in constructing medical devices. There is a long list of common problems, which include:
- Signal Interference
- Device Malfunction
- Data Corruption
- Reduced Device Lifespan
- Safety Hazards
- Regulatory Non-Compliance
- User Interface Errors
- Communication Failures
- Increased Electromagnetic Emissions
- Audio Noise
These issues can significantly affect patient care and healthcare provider’s ability to deliver services effectively. Therefore, the proper selection, installation, and maintenance of EMI gaskets are crucial for operating medical devices within their electromagnetic environment.
