Medical product temperature point indicator, thermochemical

A medical product temperature point indicator, thermochemical is a small, single-use device designed to be affixed to containers holding temperature-sensitive medical items such as blood or pharmaceuticals. It provides a visual, non-reversible colour change when a specific temperature threshold is reached or exceeded, signalling potential compromise of the product’s viability due to heat exposure.

These devices are typically supplied as self-adhesive units containing a heat-sensitive chemical patch that activates upon attachment to the product container. As single-use items, they are not intended for reuse and are regulated based on their function as indicators rather than as active medical devices, with classification depending on the jurisdiction and associated risk assessment.
