PURPOSE:To miniaturize the title apparatus as a whole and to simplify the constitution thereof, by mounting an automatic opening and closing valve becoming an opening state for a definite time after the feed of water by a water feed pump is started and the water feed pump stopping the feed of water to a water feed pipe for a definite time after a water level sensor senses the max. water level in an excretion container. CONSTITUTION:An excretion container 3 is assigned to individual patient for his exclusive use and all of urine per day is discharged in the same container. A user measures an amount of urine per day on the basis of the scale line 20 on the front surface of the excretion container 3 and subsequently sets a switch means 19 with a timer to a washing start state. When an automatic opening and closing valve 15 becomes an open state for a definite time, a water feed pump 17 is started and washing water having a detergent mixed therein is injected in the excretion container 3 from the upper part thereof and, further, only washing water is injected and the water level before washing, that is, an urine level L1 rises to the max. water level L2. At this time, the water level sensor 11 senses the max. water level L2 and the switch means 19 with the timer operates the timer for a definite time to stop the water feed pump 17. The washing water is entirely drained along with the detergent by a siphon theory. |
