Design and Implementation of a Precision Oxygen Delivery Control System in Facial Masks

Oxygen inflammation cases have been constantly recorded, ending up in serious burns for the patients and/or even fire breakouts in hospitals. The present work reports the development of a precision oxygen inflammation prevention system, which could be utilized during oxygen therapy. The present approach relies on the utilization of specific contact points on a mask attached to a patient's skin. At the same time, a control system permits or interrupts oxygen flow. Since oxygen flow response times are crucial, capacitive touch sensor technology has been chosen. The final flow control is performed by a properly programed micro-controller. The methodology described in the present work, is expected to have a positive impact in patient management as well as result in savings concerning oxygen reserves in hospital management. Further on, the present apparatus is fully compatible with oxygen masks utilized in a hospital or primary health provider.
