ABSTRACT:
A disposable mouth to mouth resuscitation device consisting of a pair of tubular members cemented together in end to end relation with a pair of valve discs in contact with each other interposed therebetween; one of the valve discs being rigid and the other flexible. Upon the person performing the resuscitation breathes into the tubular member having the rigid valve disc adjacent thereto, the flexible valve disc is made to flex away from the rigid valve disc and permit the air to pass through the second tubular member and into the person's mouth being resuscitated. Each exhalation of air and any vomit emitted by the person being resuscitated cause the flexible valve disc to seal against the rigid valve disc and be discharged to the atmosphere through openings formed in the side of the second tubular member. When the person performing the resuscitation breathes into the first tubular member, he closes off the openings with his fingers as well as the nostrils of the person being resuscitated and removes them when the latter exhales.
