Urine and/or feces disposal systems are expected to replace the diapers currently used for urine and feces disposal for the elderly with urinal and/or fecal incontinence. The are designed to detect the urine and/or feces, cleanse the excremental body organs with water transported from a cleansing water container in the main body, suction them into a fluid waste storage container for future disposal, and dry the area with hot air supplied also from the main body. These systems thus could relieve the chores of a caregiver and could also enhance the patient's hygiene. We reviewed in this paper the detection systems of urine and feces, the main components of the urine and feces disposal systems, and tried to classify the systems currently available in the market.

This paper proposes a design of controller for automatic evacuation disposal system with suction, collecting, washing, and drying functions to be useful for excretion care of long-term bedridden patients. It is desirable that the system can discriminate excreta such as feces and urine severally, and dispose of them without having additional efforts of caregivers. This paper describes a method to improve the discrimination ability by using multi-sensors, and proposes disposal processes according to the type of excrements. As a result the automatic evacuation disposal system can perform an efficient operation in the excrement care. Experimental results using artificial excrements show the automatic evacuation disposal system is effective and feasible to assist the excrement care.
