Patent ID: 8182437

Claim:
A pneumatic compression device, comprising: a compression pump configured to output a pressurized fluid via an output; a fill/exhaust valve configured to connect the compression pump to one or more cell valves when in an open state, wherein the fill/exhaust valve is further configured to connect the one or more cell valves to the atmosphere when in a closed state; a transducer, wherein the transducer is configured to sense a pressure level at the fill/exhaust valve; a plurality of cell valves, wherein each cell valve corresponds to a cell, wherein each cell valve is configured to connect the fill/exhaust valve to the corresponding cell when in an open state; and a controller in communication with the transducer, the fill/exhaust valve and the plurality of cell valves, wherein the controller is configured to determine a state for each of the fill/exhaust valve and the plurality of cell valves based on at least the pressure level sensed by the transducer, wherein each state comprises one of an open state and a closed state, wherein each of the fill/exhaust valve and the plurality of cell valves comprises a portion of a first bore of a manifold and a portion of a second bore of the manifold, and wherein the manifold comprises a plurality of spacers, wherein each spacer is positioned on a distal side of a corresponding valve, wherein each spacer is operable to separate the portion of the second bore of the corresponding valve from the portion of the second bore of an adjacent valve or the atmosphere, wherein a spacer corresponding to the fill/exhaust valve is further operable to separate the portion of the first bore of the fill/exhaust valve from the portion of the first bore of the adjacent cell valve.
