Drug spill warning device

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.

Claims

1. A drug spill warning device suitable for installation on a human body, the human body having a needle, a flexible tube connected to the needle, and a film attached to the human body and covering the portion of the needle and the flexible tube, the drug spill warning device comprising: a detection unit fixed between the film and the human body by the film, the detection unit including a humidity detector capable of detecting humidity and an absorbent layer in contact with the humidity detector and capable of absorbing liquid; and a warning unit including a warning transmitter connected to the humidity detector and an adhesive layer disposed on the warning transmitter and detachably attached to an object, the warning transmitter receiving a humidity message from the humidity detector and sending a warning message to the outside.

2. The drug spill warning device as described in claim 1, wherein, The humidity detector of the detection unit has two wires that are each connected to the alarm transmitter of the alarm unit. The end of each wire that is not connected to the alarm transmitter is connected to the absorption layer. When the wires form a path through the absorption layer, the alarm transmitter receives the humidity information.

3. The drug spill warning device as claimed in claim 1, wherein, The humidity detector of the detection unit has an RFID tag and a humidity detection module that is signal-connected to the RFID tag. The alarm transmitter has a reading module that is signal-connected to the RFID tag and a signal transmission module that is electrically connected to the reading module and can send the alarm message. When the humidity detection module receives the electromagnetic wave sent by the reading module, it will generate an induced current and generate an induced electromagnetic wave. The induced electromagnetic wave will transmit the humidity information measured by the humidity detection module back to the reading module.

4. The drug spill warning device as claimed in claim 1, wherein, The detection unit also includes a waterproof layer disposed on the outside of the absorbent layer, which defines at least one moisture-detecting area for the absorbent layer to be exposed.

5. The drug spill warning device as claimed in claim 1, wherein, The warning unit also includes a power supply that provides power to the warning transmitter.
