Wet bed alarm and temperature monitoring system
First Claim
1. A monitoring system for detecting urine and monitoring body temperature, comprising:
- an electric circuit for activating indicator means, having a pair of electrodes having a break in continuity,a lead member extending from each said electrode, said lead members being in a spaced apart relationship from each other,a sheet of material extending over and resting against said lead members for absorbing and retaining urine to permit said urine to provide a conductive path between said lead members to complete said circuit and activate said indicator means,a flexible sheet of waterproof material to which said lead members are joined,heat sensor means for monitoring the temperature of a person resting against said sheet of material,said heat sensor means being of the washer variety, and being secured to said flexible sheet with button members,said heat sensor means comprising two independent and spaced apart heat sensors serving to also measure the temperature differential at two different points on said flexible sheet to indicate by the magnitude of said differential whether the sheet is wet.

Abstract
An monitoring system for detecting urine includes an electric circuit for activating an indicator, having a break in continuity bordered by a pair of electrodes, a lead member extending from each electrode, the lead members being in a spaced apart relationship from each other, and a sheet of hydrophilic material extending over and resting against the lead members for absorbing and retaining urine to permit the urine to provide a conductive path between the lead members to complete the circuit and activate the indicator. The indicator is either a light or a sound generator. The system may additionally include a flexible sheet of waterproof material to which the lead members are joined. The flexible sheet of waterproof material optionally fits into a pocket of a bed pad. The system may additionally include a heat sensor for monitoring the temperature of a person resting against the sheet of hydrophilic material. Two independent and spaced apart heat sensors are optionally provided and measure the temperature differential at two different points on the flexible sheet to indicate by the magnitude of the differential whether the sheet is wet. The system also preferably includes a water-permeable cover sheet which extends across a side of the sheet of hydrophilic material opposite the lead members. Several of these systems may be independently monitored at a single annunciator panel.
