ABSTRACT:
A disposable rebreathing canister is disclosed for administering oxygen and anesthesia to patients. The canister essentially comprises a housing for a scrubber, including a manifold plate and a rigid container, and a flexible liner disposed within the rigid container. The liner forms an imperforate barrier between the interior of the rigid container and the manifold plate. A scrubber disposed between the manifold plate and liner chemically reacts with gases conducted to it through one of a pair of coaxial passages formed in the manifold plate. Reacted gases are then moved through a tortuous passage either back to the other one of the coaxial passages or removed through an exhaust port.
The interior of the rigid container connects with a source of pressure that allows the flexible liner to be collapsed, thus forcing treated gases, fresh oxygen and anesthesia into the lungs of the patient.
