Health care

automotive For several equipment used in medical electronics, resistors components with two critical characteristics - tolerance to high voltage and surge protection - are vital to their design and safe, efficient functioning.

A recent trend in the healthcare industry is the transformation of medical diagnostic instruments from institutions to individuals. Several gadgets are moving from hospitals, clinics and laboratories to households and individual wearables. Blood test home kits and heart rate measuring gadgets are the best examples of this phenomenon.

However, the human body is analogue in nature, so highly reliable passive components are required to complement the modern digital electronic medical systems. The important areas where passive components find wide application are:

  • Human contact devices -

    Which have physical contact with the human body. These include defibrillators, Electro-Cardiogram (ECG) and Electro-Encephalogram (EEG) devices.

  • Imaging systems -

    Include diagnostic equipment like X-Ray, CT-Scan, Utra-sound and MRI scans.

  • Analytical Equipment and Instrumentation -

    Includes in-vitro devices (IVD) and other laboratory apparatus.

The resistive components used as part of these devices are:

  • Pulse withstanding resistors -

    Used in defibrillators for inducing normal cardiac rhythms by shocking patients with an abrupt electrical surge.

  • High ohmic value resistors -

    Used as high gain amplifiers in ECG.

  • High-voltage resistors -

    Used in X-ray head supply dividers.

  • Thin-film resistors -

    Used in Ultrasound transducers.

  • Metal Foil or Thin film precision resistors -

    Used for high stability in IVD analysis equipment.
