Colour-indication patient thermometer

A colour-indication patient thermometer is a single-use device that measures body temperature through a visible colour change in heat-sensitive chemical cells. It is designed for use on the skin, in the mouth, rectally, or under the arm to provide a simple, visual indication of temperature without electronic components.

As a single-use device, it is intended for one patient and one use only, reducing cross-contamination risk. These devices are typically regulated as low-risk medical devices and are supplied sterile or non-sterile depending on intended use, with no reusable parts or electronic readouts.
