Claim 9:
10. A pneumatic therapy apparatus with overlapped compression comprising a wrap and a controller:
wherein the wrap includes an outer wrap and an inner air bladder set;
wherein the controller is fixedly connected to, detachably connected to, or separately connected to the outer wrap;
wherein the controller is connected to an inner component housing, and the inner component housing contains an inflation motor and an integrated control board;
wherein the inflation motor is controlled by the integrated control board;
wherein the inner air bladder set includes one or more than one set of a first air bladder and a second air bladder that are overlapped;
wherein the size of the first air bladder is bigger than that of the second air bladder, and the second air bladder is welded and located outside a lower section of the first air bladder;
wherein the boundary of the first air bladder is seal welded with one or more than one air flow hole on its lower section, and the boundary of the second air bladder is seal welded on the lower section of the first air bladder, making the second air bladder cover the air flow hole on the first air bladder;
wherein there is a flow nozzle directly connected to the second air bladder without any part of the flow nozzle going through the first air bladder for the inflation motor to inflate the second air bladder first and then the first air bladder;
wherein the air flow hole on the lower section of the first air bladder creates one or more than one air flow passageway between the first air bladder and the second air bladder;
wherein through the air flow passageway, the air flow enters the first air bladder from the second air bladder to achieve overlapped compression between the first air bladder and the second air bladder;
wherein there are a first connection tubing between the flow nozzle and the inflation motor;
wherein the flow nozzle is connected to the inflation motor through the first connection tubing;
wherein the inflation motor generates air flow;
wherein the air flow from the inflation motor enters the second air bladder through the first connection tubing and the flow nozzle;
wherein when the air pressure in the second air bladder rises to a certain level, the air flow starts to enter the first air bladder from the second air bladder through the air flow passageway;
wherein the controller contains a solenoid valve and a pressure detection valve;
wherein the solenoid valve, pressure detection valve, and the inflation motor are electrically connected to the integrated control board;
wherein the first air bladder includes an second nozzle;
wherein there are a second connection tubing between the second nozzle and the pressure detection valve;
wherein the second nozzle is connected to the pressure detection valve via the second connection tubing;
wherein when the inflation pressure inside the first air bladder and the second air bladder reaches a preset value, the pressure detection valve detects and sends signals to the integrated control board;
wherein after receiving signals, the integrated control board stops the inflation motor;
wherein after the inflation motor stops, the first air bladder and the second air bladder maintain the inflation pressure at the preset value for a certain period of time prior to deflation, or immediately deflate through the flow or second nozzle, the connection tubing, and the solenoid valve in sequence;
wherein the wrap is used to cover different treatment areas, including leg, arm, foot, hand, head, buttock, waist, abdomen, back, or a combination of the above;
wherein the second air bladder is located on a side of the first air bladder that is farther away from a human body while using, and the second air bladder is completely overlapped on the side of the first air bladder; wherein the inner component housing is hidden inside the outer wrap; wherein the controller is outside the outer wrap; wherein the inner bladder set is adjacent to the inner component housing; wherein the outer wrap is between the controller and the inner component housing; wherein the wrap includes an optional patch outside to provide hot/warm and/or cold/cool; the inner component housing is hidden inside the outer wrap;
the controller is outside the wrap;
the inner air bladder set is adjacent to the inner component housing;
the outer wrap is between the controller and the inner component housing;
the wrap includes an optional patch outside to provide hot/warm and/or cold/cool; and wherein the inner component housing contains a valve.
