Automatic Regulation and Monitoring of CPM Machine

The aim of this project is empowered by adding independency to the individuals during Continuous Passive Motion. In this project, a Continuous Passive Motion CPM Machine is designed that will enable the patient to move their leg continuously. This project is for measuring the muscle oxygen of the patient who is using CPM and to control the motion. The oxygen level is measured by using the Near Infrared spectroscopic principle and is attached as a device to the patient and it continuously monitors the oxygen level. This is performed after surgeries like total knee replacement and anterior circulate ligament reconstruction. Patient who has undergone these surgeries must be treated with CPM machine. But the machine could not identify the tearing of the muscles during the procedure and this could lead to post surgical trauma. To prevent these damages to the muscles NIRS is attached to this mechanism. It detects the oxy hemoglobin level in the tissues and stops the machine when the muscle oxygen reaches the threshold value 90 mmHg . The potentiometer is used to vary the oxygen level manually since the oxygen level below the threshold cannot be measured practically. The machine continuously works when the oxygen level is above the threshold. Moreover, ESP8266 module is used to monitor the oxygen level continuously and the data is stored in the cloud for future references. Muniraj. N. J. R | Afsana Azi Firdosh. A | Kavipriya.
