Description

ABSTRACT A resuscitator device for providing a physical shield between the rescuer and a victim requiring mouth-to-mouth resuscitation, and comprising a flexible sheet to conform to the contour of the face of the victim in the area around the mouth and nose. A mouth opening is centrally formed in said sheet. A hollow rigid tube surrounds and is secured to the periphery of said mouth opening and depends downward therefrom to an outer end, for inserting into the mouth of the victim. A self closing, one way valve is contained in the tube, and includes a flexible, sleeve having an air inlet open end in communication with the mouth opening and an air outlet end adjacent the outer end of the tube which is normally closed from the action of a spring strip secured to the sleeve adjacent the outlet end. An air tight seal is made with the lips of the rescuer and victim separated by the sheet functioning as a shield, when the rescuer exhales a deep breath under presssure into the inlet of the valve. The forced air overcomes the resilient force of the spring strip and opens the sir outlet, for discharging the air inside the victim's mouth. When the breath is fully exhaled, the spring strip resiliently closes the air outlet to prevent any back flow of air, mist or liquid from the victim to the rescuer. The rescuer then moves his lips away from the sheet to take another deep breath and thereby breaks the seal to permit exhaling from the victim. Grooves formed in the victim's side of the sheet provide air pathways to the outside and prevent blockage of air from the mouth of the victim. An irregular non-smooth surface is formed on an area of the sheet to prevent clinging of the sheet to the nose, which could inhibit air flow out from the victim's nose.
