Abstract
Apparatus for compressing the chest of a patient to stimulate blood circulation, includes a torso wrap (32) that has a back portion (40) lying at the back of the patient's chest and a front portion (42) lying at the front of the patient's chest, and includes a compressor assembly with an actuator (16) having a pressing member (12) that can apply a series of force pulses to the sternum of the patient to stimulate blood circulation. The actuator is energized by pressured fluid, with a controlled pressured fluid source (20) connected by an elongated flexible hose (24) to the actuator so the pressured fluid source and a control (22) can lie on the ground and only the actuator lies on the torso wrap. The actuator includes a cylinder (66) and a plurality of telescoping piston parts (64, 66) to provide a long stroke in an actuator of small height. A stabilizer (150) that limits tilt of the actuator from the vertical, includes a saucer-shaped member that presses against the front of the patient.
