新型双侧患者搬移机器人的创新设计与实验

Innovative Design and Experimental Research for a New Bilateral Patient Transfer Robot

基于医院患者搬移过程中出现的工作强度大、搬移效率低、舒适性差等问题,设计了一款新型双侧患者搬移机器人。首先,根据患者临床搬移过程,抽象出两自由度患者搬移模型,分析出双侧患者搬移过程基本工作原理;其次,将双侧患者搬移机器人分解为患者搬移部和车体部,对其进行了详细的结构设计;之后,进行了整个机械装置的设计,搭建了样机的控制系统,并设计了遥控器和触摸屏;最后,通过实验的方法测试了该样机的运动性能和承载能力,从实验效果来看,样机可以完成相应的运动功能且承载能力可达150 kg。

Based on the problems of high work intensity,low efficiency and poor comfort in the process of patient transfer in the hospital,a new type of bilateral patient transfer robot is designed.Firstly,according to the clinical moving process of the patient,the two-degrees-of-freedom patient transfer model is established,and the basic working principle of the bilateral patient transfer process is analyzed.Secondly,the robot is divided into the patient transfer part and the body part.The structures of these two parts are designed respectively.Thirdly,the entire mechanical device is designed,the control system of the prototype is developed,and the remote control and touch screen are designed.Finally,the motion performance and load-bearing capacity of the prototype are tested and the results show that the prototype can complete the corresponding motion function with the load-bearing capacity up to 150 kg.
