Abstract

An improved moisture-sensing device, preferably combined with an improved lead, is provided which represents a significant advance in the state of the art in the treatment of enuretic children. Both sensor and lead utilize a special type of conductive polyvinyl cloth and the components are connected by silver-impregnated Velcro®.

Claims

1. In an anti-bed-wetting device consisting of an electrical sounder adapted to be triggered by the closing of a pair of contacts, a sensor, and an electrically conducting means between said sounder and said sensor, the improvement comprising a sensor comprising two relatively long, narrow strips of a conductive fabric wherein said fabric has a conductive side and a nonconductive side, said strips being of substantially the same size and configuration and being placed in back-to-back relationship with the nonconductive sides of each sheet in contact with the other and a sheet of fabric or cloth enclosing said strips and at one end of said sensor two small patches of electrically conductive Velcro®

in back-to-back relationship, with the attaching sides of the Velcro®

facing outwardly, one of said Velcro®

patches being in electrical contact with each of said strips.

2. The device of claim 1 wherein said electrically conductive means comprises a pair of face-to-face conductive fabric strips each of which has a patch of inwardly facing conductive Velcro®

at the terminal ends thereof, said strips being enclosed in a fabric sheath and said Velcro®

strips adapted to mate with said corresponding patches on said sensor.
