Abstract

A drug spill warning device includes a detection unit and an alarm unit. The detection unit includes a humidity detector and an absorbent layer that contacts the humidity detector and absorbs liquid. The alarm unit includes an alarm transmitter connected to the humidity detector and an adhesive layer disposed on the alarm transmitter and detachably affixed to an object. When a drug spills, the absorbent layer absorbs the drug, providing initial protection. Simultaneously, the humidity detector detects the increased humidity caused by the absorbent layer absorbing the drug and transmits the humidity information to the alarm transmitter. The alarm transmitter can send an alarm message to the outside world via sound or text message to promptly alert medical personnel to assist in handling the spill.
