  • Publication number: 20090145234
    Abstract: A method of measuring pressure for a cell in a pneumatic compression device may include performing an inflate/exhaust cycle including for one or more cells of a plurality of cells in a pneumatic compression device, inflating a cell to a target pressure, wherein the target pressure is based on at least a desired pressure, measuring a pressure of the cell, determining an overpressure value associated with the cell based on at least the measured pressure, determining a subsequent target pressure associated with the cell based on at least the measured pressure and the overpressure value, deflating the cell, and inflating the cell until the subsequent target pressure is achieved.

  • Publication number: 20080281240
    Abstract: Pneumatic compression devices and methods for using the same are disclosed. A pneumatic compression device may include a compression pump, a fill/exhaust valve, a transducer, a plurality of cell valves, and a controller. The compression pump may output a pressurized fluid via an output. The fill/exhaust valve may connect one or more cell valves to the compression pump when in an open state and to the atmosphere when in a closed state. The transducer may sense a pressure level. Each cell valve may correspond to a cell and may connect the fill/exhaust valve to the corresponding cell when in an open state. The controller may determine a state (either open or closed) for each of the fill/exhaust valve and the plurality of cell valves based on at least the pressure level sensed by the transducer.

  • Patent number: 5074285
    Abstract: A thermal applicator method using a support garment which encloses a human extremity such as an arm or a leg and includes a plurality of pockets adapted to receive thermal elements for retaining such thermal elements adjacent a specified portion of the human extremity and the combination of such a thermal applicator with a pressure applicator. The method comprises applying thermal treatment to a selected portion of the arm or leg and simultaneously applying a plurality of decreasing pressure steps the arm or leg from distal portions to proximal portions thereof.

  • Patent number: 4922893
    Abstract: An improved method and apparatus for promoting flow of a body fluid within a human limb, which has been subjected to an amputation procedure, wherein a novel distal inflatable cell having a pair of inflatable cell portions, one of which encompasses such a limb adjacent the stump end thereof and the other of which extends transversely across the stump end thereof, is utilized in a novel method of therapy to treat Lymphedema and similar fluid accumulation disorders of the extremities.

  • Patent number: 4747398
    Abstract: An adjustment apparatus for adjusting the pressure applied in the multiple cells of an inflatable medical garment with the pressure adjustment being achieved by a drive apparatus interconnecting adjustable pressure regulating devices, the drive apparatus and the respective pressure regulating devices including adjustment elements which permit adjustment of each pressure regulating device independently of others of the pressure regulating devices such that the drive apparatus may be utilized to adjust, in unison, multiple pressure regulating devices having selectively variable pressure differential relationship between any pair of the multiple pressure regulating devices.
