介護用オムツの尿吸収量評価を目指した静電容量変化検出方法に関する研究

抄録

Two type of disposable diapers, pad-type and tape-type, are used in combination in the nursing homes for the elderly in Japan. A waist-shaped torso was wore the pad-type and the tape-type diapers. To quantitative evaluate the urine absorption volume of the pad-type diaper, the electrodes were attached to the outer surface of the tape-type diaper. The electrodes evaluate the urine absorption volume of the pad-type diaper by the capacitance change. Saline of 100 mL was injected five times to the pad-type diaper. The torso postures were the supine and 30 degrees lateral positions. In both postures, the capacitance of the electrodes increased linearly with the increase in the saline absorption volume of the pad-type diaper. In each absorption volume of saline, the capacitance of the electrodes in the supine position was higher than the capacitance of the electrodes in 30 degrees lateral position.
