Cardiopulmonary resuscitation device
First Claim
1. A device for administering cardiopulmonary resuscitation to a heart attack victim comprising, a main horizontally disposed base, a normally upstanding post from said base, pivotally attached at an upper end intermediate the length of a generally horizontally extending upper beam member, a spring-loaded pneumatic cylinder and piston assembly, pivotally connected between respective rear end portions of said base and beam, a chest abutment member adjustably suspended in a generally vertical attitude relative to a front end of said beam, and valve means connected in a pneumatic system to receive a flow of pressurized oxygen from a suitable source such as a commercially available pressurized oxygen tank, and means to continuously sequentially operate said valve means to, first, direct a flow of pressurized oxygen through said system to said cylinder to actuate said piston in a manner so as to rock said beam about said intermediate upper end pivot to cause said chest abutment to descend into contact with and to exert a pressure on the heart area of a heart attack victim positioned therebeneath, and, second, to exhaust said oxygen in said cylinder through said system under the influence of said spring-loading, and to direct said exhausted oxygen through said valve means and a conduit connecting to a face mask for positioning over the nose and mouth area of the victim.

Abstract
A device is disclosed for administering cardiopulmonary resuscitation to a heart attack victim. The device includes a frame comprised of a main support base assembly and an upright portion with a top arm portion which is pivoted intermediate its length to the upright. A conventional air cylinder assembly is pivotally connected between first ends of the base assembly and pivotal arm to actuate the pivotal arm to apply appropriate pressure to the chest area of a victim, disposed in a prone position beneath an abutment member, adjustably carried by a second end of the pivotal arm. A conventional tank of pressurized oxygen is connected to a pneumatic system to cyclically operate the air cylinder assembly to apply the pressure to the chest area and to feed the oxygen through a conventional face mask, connected in the pneumatic system and disposed over the nose and mouth area of the victim. The upright portion is collapsible on the base assembly for storage purposes.
