Thermal needle

A thermal needle is a thin needle used to measure body temperature. It consists of a temperature-sensitive element enclosed in a thin metal body in the form of a needle.

The operating principle of a thermal needle is based on a change in the electrical resistance of a temperature-sensitive element when the temperature changes. When the tip of the needle comes into contact with the skin, heat exchange occurs, as a result of which the temperature of the sensitive element becomes equal to body temperature. An electrical signal from the thermal needle is sent to a measuring device that displays body temperature.

Thermal needles are used in medicine to quickly and accurately measure patients' body temperature. The advantage of thermal needles is their compactness, convenience and safety of use. They allow you to measure temperature almost anywhere on the body without causing discomfort to the patient.
