Medical devices can be divided into clinical testing, diagnostic monitoring, surgical instruments, nursing instruments, therapeutic instruments and other categories according to their use. Due to the different use of the environment, in order to ensure that the touch does not appear misoperation, the selection of touch screen materials and processes is particularly complex.

The five-wire resistive touch panel is used in large and medium-sized medical equipment with high reliability and good stability.

The four-wire resistive touch screen is suitable for small and medium-sized touch product applications, and the resistive touch panel is less susceptible to external interference, so it is more stable and safe to use on medical devices.

The advantages of capacitive touch screen are light touch, beautiful device assembly and good sealing, but in special places in the external environment, it is vulnerable to static electricity, high-frequency electromagnetic interference, and the characteristics of other electronic components of the equipment, and it needs to go through strict and complex testing and verification, and the stability of touch is relatively poor.
