Abstract
An improved overall arrangement is provided for resuscitators of the class adapted for administering substantially pure oxygen from a pressurized source thereof, and especially those of the kind functionally employing a demand responsive type oxygen supply valve in conjunction with a manually compressible squeeze bag. The demand type supply valve is mounted on and communicates with the end of the squeeze bag opposite from the end thereof on which the patient non-rebreathing valve (and the face mask associated with the latter) is mounted and communicates with the bag. In addtion to the operational and constructional advantages of the improved organization of the overall resuscitator apparatus, the construction and operation of various components thereof, including the demand type supply valve and the non-rebreathing valve, are individually improved in manner both contributing to better performance of the overall resuscitator apparatus and representing novel valving devices having potential utility even in other applications.
