A hand washing detector device, suitable to be fitted to a person possibly on the hand or wrist, comprises a sensor (2) for sensing a hand washing event and a timing module (12) responsive to the sensor. The device may also include an alarm system (6, 8, 10) wherein the timing module (12) activates the alarm system (6, 8, 10) when a first predetermined time limit is exceeded between hand washing events. The alarm may be audible (6), vibratory (8) and/or visual (10) and the sensor (2) may detect the presence of water or any other chemical present during hand washing. The device may help in infection control by monitoring hand washing and reminding people to wash their hands regularly. |
