Touchscreen technologies in the medical field

Touchscreens for medical devices

Medical technology places very diverse and sometimes very different demands on the operation of devices, the safety of devices and their users, as well as the visualization of data. In addition, there are special influences that result from the fact that a medical device can sometimes be used in completely different environments and conditions.

As an example, the use of a defibrillator in the operating room and in emergency medicine can be mentioned. The use must also be guaranteed in extreme weather conditions. This meant environmental conditions that were far beyond those of the hospital.

Intuitive touchscreens for home health care

Furthermore, when designing touchscreens for medical devices, it must be taken into account that the use is increasingly shifting from the hospital environment to the home environment. Increasingly, laypeople are operating medical devices in the home environment that are not or inadequately trained in their use. This places different demands on safety and an HMI (Human Machine Interface) that is as intuitive to use as possible.

Due to the operation of the devices by medical laypersons, patient safety becomes even more important.

Touchscreens in medical technology

A touch screen for use in medical technology should meet the following conditions:

  • The highest possible transparency and high contrast
  • Good display of many gray or color levels
  • Low reflection surface
  • Low parallax: exact positioning of the fingers over the image content
  • Low touch response time; Efficient error correction
  • Easy to clean, resistant to detergents and disinfectants
  • Robust, scratch-resistant and splinter-free
  • Good electromagnetic compatibility
