Low Cost Anesthesia Injector Based on Arduino with Multi Paramaters

In general practice, hospitals perform several operations which are considered as therapeutic condition for the patients. For such cases, anesthesia is a significant drug that would be infused to the patient which makes them in anaesthetized condition. If the surgery lasts for prolonged period of time, it becomes unfeasible to deliver the drug at a single stroke. Critical condition occurs, if there is excess of drug given to the patients, also when fewer amount of drug is delivered, the patient will become conscious at the middle of the surgery. Even if anesthetist fails to administer the drug to the patient, the procedure becomes tedious. In order to overcome these problems, the automatic anesthesia injector is implemented using microcontroller by receiving the signal from the keypad that customizes the working of stepper motor. After which it directs the drug to the infusion pump at one ml to the patient. If any uncertain condition occurs, the alarm will ON.
