Patent ID: 7755497

Claim:
A urine sensor to be used in a urine receiver comprising a urine collecting member to be put on a wearer's body with the inner side placed against a urethral and a skin thereabout and a urine detecting member to be interposed between said skin and said urine collecting member and serving to detect urine discharged from said urethral, wherein said urine receiver is connected to a vacuum suction means provided separately of said urine receiver so that said vacuum suction means may be activated in response to a detection signal output from said urine detecting member to suck said urine into said urine collecting member, wherein said urine sensor comprises thermoplastic synthetic resin film having a length direction, a width direction and a thickness direction being orthogonal one to another, a pair of electrodes formed on a surface of said film, each of said electrodes having opposite top and bottom surfaces, wherein the bottom surface is covered by said film, and an electrically insulating coating formed on said surface to cover the top surface of each of said electrodes, said film being formed along a center line with an opening, which is elongated in the length direction, and both side portions of said film along said opening being respectively provided with said electrodes extending in said length direction, each of said electrodes being provided at one of opposite ends thereof as viewed in said length direction with an electrical connector to be connected to said vacuum suction means, and said insulating coating being formed between said opposite ends of said electrodes with a plurality of through-holes in which said electrodes may come in contact with said urine flowing into said through-holes, wherein said through-holes extend in the thickness direction through the insulating coating, without extending through the electrodes, and partially exposing the top surfaces of the electrodes.
