Assisted intravenous anaesthesia drug delivery system

The process of administrating anaesthesia into the patient's body is very crucial during any surgery. The intravenous method of anesthetic drug delivery is widely used in comparison to inhale as they provide steady maintenance and recovery rate is faster. The anaesthetist administers a regulated dosage of anaesthesia to the patient which depends on the essential body functioning parameters such as heart rate, depth of anaesthesia, body temperature etc. Conventionally anaesthesia is administered manually which may lead to anesthetic complications due to inappropriate dosing. To reduce the chances of anaesthesia complications, a system has been proposed which automatically regulates the anaesthesia dosage. The objective of this work is to design and develop a prototype device for assisted intravenous anaesthesia delivery system that would help to administer anaesthesia as per the specific requirement of the patients undergoing surgeries. The prototype device has an embedded PID based control algorithm that help anaesthesiologist to calculate and regulate dosage of the drug at various stages of the surgery. To ensure highest safety for the patients, various sensors have also been integrated into the device that simultaneously track critical parameters like Bi-spectral Index, temperature, pulse oximetry and cardiography and in case of deviations generate alarm for immediate corrective action.
