Abstract: A digital display air pump includes a rectangular, box-shaped body having a standard AC power cord extending from it, two air supply output ports, and a control and information panel located on its front side with user-operated buttons, a digital display for showing air pressure and alarm codes, a variable air pressure set dial, and status lights. Within the hollow interior of the body is an air compressor, a dual-output electromechanical valve having to two air output tubes, an air pressure sensor, an AC power connection, an internal loudspeaker, and an electronic circuit board controlling the digital display air pump's function. The air supply output ports, an extension of the air tubes within the body, supply air to Intermittent Pneumatic Compression (“IPC”) Therapy device garments through flexible air supply tubes.

Abstract: A compact mini air pump includes a rectangular, box-shaped body having a standard AC power cord extending from it, two air supply output ports, and a control and information panel with user-operated buttons and status lights located on its front side. Within the hollow interior of the body is an air compressor, a dual-output electromechanical valve having to two air output tubes, an air pressure sensor, a DC battery power supply, an AC power connection, and an electronic circuit board controlling the mini air pump's function. The air supply output ports, an extension of the air tubes within the body, supply air to Intermittent Pneumatic Compression (“IPC”) Therapy device garments through flexible air supply tubes. The mini air pump device is sized to be held by one hand for portability.

Abstract: A micro bleed hole connector for use in intermittent pneumatic compression devices includes a body made of a material that is sturdy, durable and compression resistant. The bleed hole connector resembles industry-standard air tube connectors, and has a micro bleed hose connecting its hollow lumen to the outside, ambient air. In use, the connector is inserted between the air input tube of an intermittent pneumatic compression device and an air supply tube, which is connected to an air pump. The air pump inflates and deflates the intermittent pneumatic compression device, which is placed on a patient's limb. In the event deflation of the compression device is retarded by air pump failure or air supply tube occlusion, the micro bleed hole dissipates air sufficiently to prevent injury to the patient's limb. Air dissipation through the bleed hole during normal operation is minimal and does not impact therapeutic application.

Abstract: A deep vein thrombosis prevention garment includes a body having a central panel, a left side panel, and a right side panel formed with a number of attachment straps having an integral fastener, such as Velcro® brand hook and loop fasteners. The central panel is formed with a single air chamber containing a single expandable air bladder receiving air from a pump through a flexible air supply tube. The central panel, left side panel and right side panel are formed from a single material which does not require a skin-safe liner or other combination of materials. The single chamber with nested expandable bladder is attached to the central panel. A cover panel covers the chamber having an expandable bladder, and is attached along its perimeter to the central panel. The cover panel and the body are made from the same material which can be placed against a patient's skin.

Abstract: A portable micro air pump includes a body, an air output port and a quick-disconnect air tube connector. The body is hand-sized, and has a user control and information panel with a power on/off button switch and a button switch for choosing which type of therapy garment is to be utilized, limb or foot. Status lights within the information panel show on/off and battery status, the therapy garment selected and alarm states of which the user needs to be aware. Within the body are an air compressor with an air output tube, a battery power source, and an electronic circuit board. The electronic circuit board has functional subunits including: a controller, a timer, a memory, an input/output interface, a pressure sensor, a status light driver and a power control driver.

Abstract: A deep vein thrombosis prevention garment includes a central panel formed with sequentially filled inner, intermediate and outer air chambers separated from each other with pressure resistive valves, a left side panel, and a right side panel formed with a number of attachment straps having an integral fastener. The inner air chamber receives air from a pump. When the air within the inner air chamber reaches a predetermined air pressure, the pressure resistive valve between the inner air chamber and the intermediate air chamber allows air to pass from the inner air chamber to an intermediate air chamber. When the air within the intermediate air chamber reaches a predetermined air pressure, the pressure resistive valve between the intermediate air chamber and the outer air chamber allows air to pass from the intermediate chamber to the outer air chamber. A membrane panel allows air to escape the sequentially filled air chambers.
