摘要
为解决行动不便者独立或有限人工辅助下的洗浴问题,将超声波清洗技术应用到个人卫生服务机器人中。通过分析超声波声学特性和清洁机理,研究了超声波对生命体组织的影响,建立了人体超声波洗浴的有效性和安全性之间的关系,提出了人体超声波洗浴方法:洗浴用超声波宜采用频率为40 kHz左右的脉冲波,并保证浴缸中的功率分布不大于1.5 W/cm2,洗浴中人体最大超声波辐照时间为5 min。在个人卫生服务机器人上对超声波人体洗浴的安全性和有效性进行了评价,并进行了超声波洗浴试验,试验结果表明该方法是可行的。
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.
