First Claim
1. An inflatable vest to circumferentially fit around a patient comprising:
- a belt of inextensible material sized to fit circumferentially around the patient with a width to cover a substantial portion of a chest of the patient, having an inner surface facing toward the chest, and having an aperture sized to receive a connector post of a removable bladder;
a removable bladder secured to said belt, said removable bladder having a connector post mounted thereon to form a gas passageway into the bladder, said connector post adapted to penetrate the aperture and connect to a pneumatic hose;

Abstract
An inflatable vest design for cardiopulmonary resuscitation (CPR) and for cardiac assist. The vest may include a belt that wraps around the chest of a patient, and a removable bladder that is placed against the chest and held in place by the belt. The inflatable bladder expands radially to first conform to a patient'"'"'s chest, and to apply circumferential pressure to the thorax of the patient. By cyclically inflating the bladder, the vest can be used in CPR and cardiac assist treatments. In addition, alternative vest designs are disclosed showing removable bladders. These vest improvements lower the energy consumption and make smaller and portable cardiopulmonary resuscitation systems more practical.
