Abstract
An appliance for applying a dynamic pressure wave against an extremity is disclosed. The appliance includes an inflatable cylindrical tapered cone chamber which is adaptable for surrounding the extremity. The cone chamber has a larger diameter outer end and a smaller diameter inner end and can be divided into a plurality of longitudinally extending tubular chambers. When inflated, the cone is sufficiently large and rigid to surround the extremity and prevent an exterior pressure from being applied thereto. An inflatable sleeve chamber encloses the cone chamber. The sleeve is formed of a bag-shaped bladder open at one end and closed at the other end. When inflated, the sleeve chamber defines an internal space small enough to exert a compressive force on the exterior of the cone and the extremity enclosed therein. When the cone chamber is inflated and then deflated as the sleeve chamber is inflated, the appliance will cause a pressure to be applied to a human or animal extremity which begins at the smaller diameter end of the cone chamber and travels up the extremity in the nature of a pressure wave.
