Abstract
An apparatus for detecting unintentional urination by a user includes an elongated belt of a liquid impermeable flexible material to which a urine sensing pad is detachably mounted. An electrical circuit carried by the belt, which may include a transmitter for sending a encoded signal to a receiver at a remote location, is responsive to the detection of urine by the urine sensing pad to provide an indication of this condition. The electrical circuitry is shielded from corrosive urine by the belt assembly. In one form, the urine sensing pad is detachably mounted to the belt by a combination of hook and eye fabric and snap fittings. Also, the urine sensing pad may be enclosed by a sheath of soft liquid absorbent material. In another form, the urine sensing pad is contained within a paper envelope.
