Abstract

A garment clip on device having a housing contoured on its outer surface to provide an indentation for receiving therein and holding a thin narrow adhesively coated wrap-around strip containing spaced apart conductors which when bridged by urination energize an alarm system mounted within the housing.

Claims

1. A device for detecting unintentional urination comprising:

a housing for attaching to an undergarment,

said housing containing an audio alarm means and having an outer surface thereof contoured to provide an indentation for receiving therein in surface contact therewith one end of a strip of flexible material,

an elongated narrow strip of flexible, electrically insulating material having an inner face and an outer face,

said strip containing a pair of spaced conductors extending longitudinally thereof along at least a part of its length with a surface of each conductor being exposed on the inner face of said strip,

adhesive means on said inner face of said strip along at least a part of its length

for adhering to the outer surface of the contour of said housing,

a pair of contacts extending from within said housing through said surface of the contour for each engaging the exposed surface of a different one of said conductors, and

means mounted within said housing for connection to said contacts and to said alarm means and actuated by urine occurring on the adhesive side of said strip bridging said electrodes which energizes said alarm means to provide an audible sound.

2. The device for detecting unintentional urination set forth in claim 1 wherein:

said pair of contacts being spring biased for distortion under the pressure of said strip adhering to the contoured surface of said housing.

3. The device for detecting unintentional urination set forth in claim 1 wherein:

said housing comprises a U-shaped configuration the legs of which are spaced a predetermined distance for forming a clamping means for slipping over the waistband of an undergarment.

4. The device for detecting unintentional urination set forth in claim 3 wherein:

said strip comprises a plastic material having said conductors embedded therein with a surface of each conductor being exposed along said inner face of said strip.

5. The device for detecting unintentional urination set forth in claim 3 wherein:

said legs of said housing are biased one toward the other.

6. The device for detecting unintentional urination set forth in claim 3 wherein:

said means mounted within said housing and said alarm means are arranged in one leg of said housing.

7. The device for detecting unintentional urination set forth in claim 6 wherein:

the contour of said housing is formed in the outer surface of said one leg of said housing.

8. The device for detecting unintentional urination set forth in claim 6 wherein:

said one leg of said housing is provided with a snap-on cover which cover has the contour formed thereon.
