Abstract
The conventional vacuum suction type urine collector may not be able to perform normal and automatic vacuum suction when contamination occurs between the electrodes acting as a sensor, and some users feel uneasy about the use of the urine collector as the case may be.In the controller for a vacuum suction type urine collector of this invention, the resistance between paired electrodes installed on the side of a urine receiver on a vacuum sucked-urine path extending from the urine receiver via a urine transport tube to a urine tank is measured by a controller to automatically detect urine, for actuating a vacuum suction device, wherein a detection resistor is connected in series to the abovementioned electrodes; and a manual operation switch is connected in parallel to the series circuit consisting of the electrodes and the detection resistor, to constitute a state detection circuit.
