Abstract
Abstract A training dummy for teaching resuscitation by both external cardiac massage and mouth-to-mouth resuscitation. The chest section is easily inserted into, and removed from, the remainder of the torso and, when removed, exposes all operative elements. Compression of the chest closes switches in the artificial heart to indicate the proper degree of force. For mouth-to-mouth resuscitation, an inflatable lung bladder causes the chest to rise and fall.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
96 words
A torso for a first aid training dummy which comprises: a molded main body member simulating the back, lower torso, and shoulder areas of a human, said main body member defining a recess in the chest portion thereof and a keyway in the lower portion of said recess; a rod extending vertically and centrally through said main body member closely adjacent the rear surface of said recess; an artificial body organ in said recess; and a resilient removable chest member within said recess and enclosing said organ, said chest member including a key engaging said keyway.
Claim 2
Dependent Claim
96 words
A torso for a first aid training dummy which comprises: a molded main body member simulating the back, lower torso, and shoulder areas of a human, said main body member defining a recess in the chest portion thereof and a keyway in the lower portion of said recess; a rod extending vertically and centrally through said main body member closely adjacent the rear surface of said recess; an artificial body organ in said recess; and a resilient removable chest member within said recess and enclosing said organ, said chest member including a key engaging said keyway.
Claim 3
Dependent Claim
