Abstract
A system for administering anesthesia gas and for preventing gas overflow until the patient breathing reservoir is full in order to enhance ease of use, safety, and efficient utilization of anesthesia gas. Overflow from a patient Pop-Off valve is inhibited by an Overflow Blocker valve mounted downstream in series opposition to the patient Pop-Off valve. The Overflow Blocker valve is forced open when the patient bag is full. Thus, until the patient bag is full, the loss of patient exhaled dead space gas and fresh gas is prevented.
