Raspberry Pi Controlled Anesthesia Machine

During the major surgery in the hospital the patient must be in anaesthetizing condition. If the operation lasts for a long time say suppose for 4 or 5 hours, anaesthesia cannot be given in a single stroke to the patient. Over dosage may cause a critical condition for the patient’s towards death. If lower amount of anaesthesia is given to the patient, the patient may be wakeup at the middle of the operation. To Overcome this problem, the anaesthetist administers few millilitres of anaesthesia per hour to the patient in a particular interval of time. If the anaesthetist fails to administer the anaesthesia to the patient at the particular time interval. To overcome such hazardous problems the design of an automatic operation of an anaesthesia machine based on a Raspberry pi is effective. In this system provided syringe infusion pump along with the Raspberry pi. The anaesthetist can set the level of anaesthesia in terms of millilitres per hour to administer anaesthesia to the patient after receiving the signal from the temperature sensor, Heart beat sensor and Respiration sensor, the raspberry pi controls the signal to the desire level and fed into the servo motor to drive the infusion pump in proper manner. The anaesthesia is administered to the patient according to the stepper motor rotation. If the level of anaesthesia is decreased to lower level (set level), the physician to refill the anaesthesia in the syringe pump to continue the process.
