Abstract:  In order to solve the problems of bathing of the person who can not take care of themselves, the technology of ultrasonic applied to the personal hygiene nursing robot was investigated. After the analysis of the ultrasonic acoustic characteristics, the cleaning mechanism and the irradiation injury, the relationship between safety and effectiveness of ultrasonic bathing was established. A method was presented  that the frequency, power distribution, wave type and irradiation time of the ultrasonic for person bathing should choose 40 kHz around, lessthan 15 W/cm2,  and  the pulse wave less than 5 min.The relationship between safety and effectiveness of ultrasonic bathing were evaluated on the personal hygiene nursing robot. The experiments of ultrasonic cleaning were tested. The experimental results show that the method is feasible.
