US 8,826,473 B2 · Moisture detection system

Abstract

A moisture detection and alarming system connected to a person-support apparatus has been described. The system comprises a moisture detection sheet connected to at least one pressure sensor, at least moisture sensor and a controller. The pressure sensor can be configured to send a signal to the controller. The controller can be configured to receive the pressure signal from the pressure sensor and determine the presence of a person supported on the person support apparatus. If a person is supported on the person-support apparatus then a moisture sensor is activated by the controller to sense the moisture content on a mattress pad. If the moisture content on the mattress pad is out of a predefined range then an alarming unit can be activated. The controller may further be connected to at least one of a hospital network, communication station and nurse call system.
