Abstract
A portable anesthesia administering system which includes a compact, lightweight unit that does not require a source of electrical power to provide regulated pressurized anesthesia gas to a patient. The operating elements include a disposable carbon dioxide absorber, a charcoal scavenger absorber, an oxygen pressure sensor and alarm for detecting a drop in the oxygen pressure below a pre-selected level. The unit utilizes an anesthesia vaporizer and regulator, an airway pressure limiting valve and airway inlet and outlet control valves to provide a gaseous anesthesia agent in pre-selected amounts. Attached to the disposable carbon dioxide absorber is a manifold block which provides for a plurality of anesthesia regulating and control elements to facilitate the administration of the anesthesia. Connected to the manifold block is an external breathing bag for assisting in the breathing of the patient.
