A disposable mouth to mouth resuscitation device includes a one way valve for preventing the victim\s breath, saliva, mucus or disease agents from contact with the resuscitator\s mouth or respiratory tract. The one way valve is in a plastic body from which extends a curved airway tube for placing in the victim\s mouth. At the other end of the plastic body is a flexible tube leading to a mouth piece at its opposing end, for insertion into the mouth of the resuscitator. A mouth and nose mask is connected to the plastic body, adjacent to the curved airway tube, for sealing over the nose and mouth of the victim during resuscitation. When the victim exhales, his breath and other exhaled materials are exhausted through a side port in the plastic body and into the atmosphere. The flexible tube, the mouth and nose seal and the location of the exhaust port allow the resuscitator to have one hand free to perform, when necessary, cardio-pulmonary resuscitation, monitoring of vital signs, or steps for stemming the flow of blood.

A mouth to mouth resuscitation device, comprising: (a) a flexible air tube for reaching from a victim to a resuscitator; (b) a mouth piece for the resuscitator, connected to one end of the flexible air tube; (c) a valve body having a passageway extending therethrough, said passageway connected at on
A mouth to mouth resuscitation device, comprising: (a) a flexible air tube for reaching from a victim to a resuscitator; (b) a mouth piece for the resuscitator, connected to one end of the flexible air tube; (c) a valve body having a passageway extending therethrough, said passageway connected at one end therefore to the air tube and being open at its opposite end, a base member mounted in said opposite open end and being formed with a victim airway hollow tube extending therefrom, the valve body including one-way valve means in said passageway for passing air from the air tube through the passageway and through the airway tube to the victim, and for preventing backflow of fluids from the victim through the passsageway and to the flexible air tube, said valve body including, with venting means for venting to atmosphere, fluids entering the passageway from the victim, wherein the victim airway tube is curved and of sufficient rigidity to depress the victim\s tongue when its end is oriented toward the victim\s palate, wherein the one-way valve means comprises a cylindrical bore in said passageway defining a valve seat at the one end thereof, a valve piston slidably mounted in said bore having one end engageable with said valve seat and spring means urging the valve piston toward said valve seat in a closed position, there being an exhaust port in a wall of the valve body normally communicating with the bore of the valve body and the airway tube, serving as said venting means, the port being axially spaced from the valve seat, but blocked by the piston when air is admitted under pressure from the air tube to force the valve piston away from the valve seat, and including recess means formed in a portion of the valve body wall along said bore between said valve seat and the opposite end of said bore and being angularly spaced from said port for establishing air communication from the one end of the valve body to the victim airway tube only when the valve piston is moved away from said seat to block said port, said spring means comprising a spring having one end supported on said base member and its other end bearing against the opposite end of the valve piston.
