吸痰机器人运动单元的改良设计
|
摘要
目的对该研究团队前期研发的吸痰机器人运动单元机械臂进行改良设计,提高吸痰管送管成功率。方法分析原有吸痰机器人运动单元机械臂存在的不足,从驱动方式及机械结构上进行改进,优化设计了直线导轨式吸痰机器人运动单元,并研制吸痰机器人样机。结果改良后的吸痰机器人运动单元运动稳定,能够顺利完成吸痰管的夹取、送管、回退保护以及旋转退管动作;并且有效减少了操作及运作的复杂度。送管成功率达到80%,较之前方案提高了25%。结论吸痰机器人的改良设计方案可行,直线导轨式吸痰机器人具有更可靠的操作性,有利于完善机械化吸痰操作。
Objectives This study focuses on the design optimization of the robot arm in the motion unit of our previously designed sputum suction robot,aiming to improve the success rate of suction catheter delivery.Methods The shortcomings of the robot arm in the motion unit of the original sputum suction robot were analyzed.The linear guide-way suction robot motion unit was optimized through improving the driving mode and mechanical structure and the prototype of the second generation sputum suction robot was developed.Results The motion unit of the improved sputum suction robot works stably and is able to complete clamping,delivery,retreating protection and rotating retreat of the suction catheter successfully.The operation complexity was effectively reduced.The success rate of catheter delivery was improved to 80%,which was 25%higher than that of the first generation prototype.Conclusions The improved design of the sputum suction robot is feasible.The linear guide-way suction robot gained more reliable maneuverability and was beneficial to improve the mechanized sputum suction operation.
