Changing diapers hurts prides of the patient, so that if the patient wear a panty type toilet which excrement is washed automatically, the patient's prides don't hurt. Before we did the base experiment and development for Practical use in panty type toilet. But we have some problems in last experiment. For example one of the problems is that the panty type toilet is made from with a vinyl sheet. Since it doesn't expand, it is not easy to put on taking off for the patient. So we show to be easy to put on taking off with panty type toilet, to development the method of pressure control is based on theoretical formula, to set the release valve. In addition, a pressure sore is important problem for the patient in this report. Not only the panty type toilet but also the bed for pressure sore prevention produces in this experiment.
