多功能护理床结构设计研究

Structure design and research of a multi-functional nursing bed

为解决长期卧床不起的病人和老年人护理难的问题,对专门用于病人看护的护理床进行了研究;通过对国内外相似用途的护理床设备的功能和结构进行归纳,提出了一种专门用于家庭的多功能健康护理床。通过控制4根电动推杆协调工作,实现了护理床的翻身功能和床-椅折叠功能;通过直流电机带动丝杠螺母机构和杠杆机构,实现了护理床的大小便辅助处理功能。对护理床后床板折叠过程和便盆提升过程中的力学进行了分析,得到了电动推杆轴向力和电机驱动力矩,并进行了仿真计算。利用研制的多功能健康护理床样机进行了运动试验。实验结果表明,该多功能护理床能实现所要求的功能,可以满足卧床病人或老年人的便利看护使用。

Aiming at the problems that it is difficult to take care of the long-term bedridden patients and the elderly, a multi-functional nurs- ing bed, which is suitable for the health care for the patient, was designed and manufactured. Through summarizing the similar nursing bed equipment both home and abroad, a dedicated multi-functional nursing bed using at home was proposed. By controlling four linear actuators to work in a coordinate mode, nursing bed＇s functions of turning over and bed-chair folding could be achieved. And through the feed screw drove by a DC-motor, the nursing bed＇s function of supplementary processing urination and defecation was realized. Moreover, the nursing robot＇s mechanics for the folding process of post-bedplate and the process of lifting the toilet was analyzed and the linear actuator＇s axial force and motor driving torque was obtained through the simulating calculation. Finally, the prototype of the nursing bed was manufactured and its motion function experiments were done. The results indicate that the nursing bed can meet the design requirements and is suitable for taking care of patients and elderly.
