Patent ID: 8191181

Claim:
A detection system for a toilet unit for use in a supine position, the toilet unit having: a treating body formed in a substantially T-shape by a urination and defecation container, serving as a lateral casing, of which the inside is formed in a boat shape and a washing nozzle retainer, serving as a vertical casing, which stands upright on the downstream side of the urination and defecation container, wherein: the treating body is housed in a support casing of a boat shape, an opening edge of the latter half section of the support casing is detachably provided with a vertical member adapted to cover the back surface of the washing nozzle retainer, a front edge of the vertical member and an opening edge of the first half section of the support casing provide an uninterrupted side edge section of a substantially L-shape as seen from the side, the side edge section is covered by an edge cover to closely contact the crotch of the legs and the buttocks of a patient in a comfortable manner, the washing nozzle retainer as the vertical casing is held in the crotch of the patient's legs to enable the patient to urinate and defecate within the urination and defecation container as the lateral casing, an injection nozzle provided on a head section of the urination and defecation container is provided to be capable of crushing and conveying a stool, a nozzle provided on the washing nozzle retainer is provided to wash the private parts of the patient, characterized in that a fitting sensor installed on the edge cover detects whether or not the crotch of the patient's legs has closely contacted the edge cover at a constant pressure and controls to make water supply from various nozzles impossible when the close contact between the crotch of the patient's legs and the edge cover at a constant pressure cannot be detected, the fitting sensor having a pair of electrode terminals made of conductive rubber, wherein when both electrode terminals are brought into contact with a femoral region of a patient at a constant pressure, the fitting sensor detects that the crotch of the patient has closely contacted the edge cover by a change in electrostatic capacity particular to a human body, and a water level sensor installed at a side edge section of the urination and defecation container on an upstream side detects water rising due to wash water and water from the injection nozzle and forcibly discharges the urination and defecation out of the urination and defecation container when the water reaches a predetermined level.
