Abstract
A vest for a human body has a bladder coupled to a pulsator operable to subject the vest to repeated pulses of air which applies and releases pressure to the body. The vest has a cover having a pocket accommodating the bladder, shoulder straps, and end flaps. The bladder is permanently connected to the cover. Releasable hook and loop fasteners connect the straps to chest portions of the vest and end flaps to each other. A releasable retainer secured to the end flaps prevent the end flaps and releasable fasteners from disengaging when air pressure pulses are applied to the vest. The bladder has an air chamber and a sleeve having an air receiving passage and openings to allow air to flow from the air receiving passage into the air chamber. An oval-shaped coil spring within the sleeve maintains the air receiving passage open.
