Abstract
A safe anesthetic mixture is supplied through a humidifier unit and passageway to a mask. The humidifier unit and passageway are incorporated in a device having an inlet nipple for connection to the delivery hose from a gas machine, a nipple for connection directly to a mask, and a nipple for connection directly to a rebreathing bag, with a common chamber therebetween, and a valved passageway and outlet nipple for connection to an exhaust line. The great majority of the exhaled mixture is removed through the rebreathing bag and exhaust line. Since very little of the anesthetic mixture is rebreathed, this device avoids the necessity for a carbon dioxide absorber.
