Abstract

After knee replacement surgery, a patient immediately needs a therapeutic treatment. A therapist flexes and extends the leg around the knee to eliminate the joint stiffness. The research is to design and develop a system of automatic Continuous Passive Motion (CPM) device so that patients no longer have to control it. The system will stop and return to its starting condition whenever there is patient pain. It is a force that is released by the patient in an opposite direction and will be represented as holding the DC motor shaft. A DC motor, H-bridge, microcontroller, and ADC modules are needed to develop this system. DC motor rotates clockwise with about 4V–5V as its voltage. If the DC motor receives load, the voltage will decrease and will be detected by ADC. The motor will stop if the voltage reaches 3V or less. After around 1.5s, it will rotate again with an opposite direction. The system is very sensitive to the patient pain, and if it is applied to CPM, it can improve patient safety.

自动连续被动运动治疗系统的研制

膝关节置换术后，患者立即需要治疗性治疗。治疗师弯曲和伸展膝盖周围的腿，以消除关节僵硬。本课题旨在设计和研制一种自动连续被动运动(CPM)装置，使患者不再需要对其进行控制。每当病人感到疼痛时，系统就会停止并恢复到初始状态。这是一个力，由病人释放在一个相反的方向，将表示为持有直流电机轴。该系统的开发需要直流电机、h桥、单片机和ADC模块。直流电动机以4V-5V左右的电压顺时针旋转。如果直流电动机受到负载，电压就会降低，并被ADC检测到。当电压达到或低于3V时，电机将停止。大约1.5秒后，它将再次以相反的方向旋转。该系统对患者的疼痛非常敏感，如果应用于CPM，可以提高患者的安全性。
