The problem and solution of interference and anti-interference of medical instruments

We often only talk about the issue of heat dissipation in medical electronic devices, but in fact, the interference and anti-interference of medical instruments are the more headache inducing problems.
On the one hand, medical electronic instruments are prone to interference, and on the other hand, interference sources are everywhere.
Due to the increasing number and density of various electronic and electrical equipment, the severity of electromagnetic interference is becoming more and more prominent.

Medical electronic devices are the foundation of hospital development and an important carrier for clinical diagnosis. If medical electronic devices are interfered with, it will have an impact on the life and health of patients. Therefore, actively improving the electromagnetic compatibility of medical electronic devices plays a very important role, which can improve the accuracy of clinical diagnosis and reduce the risks generated during the operation of medical electronic devices.

For medical equipment, electromagnetic compatibility issues should be considered during design. There are generally three ways to rectify electromagnetic interference: shielding, grounding, and filtering. Shielding materials or absorbing materials can be used to help solve electromagnetic shielding problems. The advanced technology institute recommends using absorbing materials to absorb electromagnetic waves and eliminate electromagnetic interference, which can effectively suppress electromagnetic interference problems in electronic devices.

Characteristics of absorbing material products

1. Wide absorption band, good absorption performance, strong weather resistance, anti-aging

2. Easy to bend, easy to process and cut

3. Soft and non fragile, lightweight, easy to process and cut, convenient to use, can be installed in small spaces

4. The product needs to be bonded or pressed onto a metal substrate to achieve good absorption effect

5. Products can correspond to diverse sizes and shapes

6. High temperature resistance and good flexibility

7. Zero halogen, lead-free, compliant with RoHs instructions

Application of absorbing material products

1. Can be used as a noise countermeasure for flexible cables for mobile devices. (Laptop, game console, mobile phone, etc.)

2. Reduce the radiation noise of various electronic devices. (Noise generated by CPU, etc.)

3. Reduce the electromagnetic radiation (SAR) of mobile phones on the human body.

4. Reduce internal EMI (resonance, crosstalk) within the shielding frame.

5. Reduce coupling, conduction, and radiation interference between low frequencies, and minimize low-frequency echo interference.
