  • Patent number: 9326683
    Abstract: Wound fluid blood detection systems and methods are described that are operable in conjunction with reduced pressure wound treatment (RPWT) systems, as well as ancillary therapy and monitoring systems applied concurrently with RPWT systems. The blood detection monitor operates by optically characterizing the content of wound fluids to the extent of identifying percentage blood content. This identification relies upon the transmission of select wavelengths of light across a volume of wound fluid to a photo detector (connected to signal processing instrumentation) capable of quantifying the absorption characteristics of the fluid. The detection components may be implemented in conjunction with either a fluid flow conduit (i.e. the reduced pressure tubing directing fluid away from the wound dressing) or more directly in association with the materials that comprise the wound dressing positioned within the wound bed itself.

  • Patent number: 9168197
    Abstract: A vascular compression system includes a compression garment and a controller for compressing a body part of a person. In some embodiments, the compression garment is a foot cuff or a leg sleeve. The controller inflates compression garment apparatus includes a compression garment and a pressurizer. The pressurizer has instructions for executing cyclic compression cycles for applying intermittent compression therapy to the body part. Each compression cycle includes an inflation phase and a vent phase. At least one of the inflation phases includes a pre-fill step and a therapeutic step. In the pre-fill step, gas pressure in the inflatable chamber may be increased at a reduced rate, and in the therapeutic step, the gas pressure in the inflatable chamber may be increased at a rapid rate.

  • Patent number: 9033905
    Abstract: A pneumatic compression garment includes a flexible member for placement on a limb of a human body. A bladder in the flexible member defines an inflatable chamber. The bladder has an opening through which the inflatable chamber is inflated. A port mounted on the bladder has an air inlet adapted for communication with a source of pressurized air and an air outlet in communication with the inflatable chamber via the opening in the bladder. Pressurized air is delivered from into the inflatable chamber for inflating the inflatable chamber and thereby applying a compression force to the limb when the flexible member is in place on the limb. An air diverter affixed to an inside surface of a first sheet of the bladder and configured to divert air entering the inflatable chamber from directly impinging against an inside surface of a second sheet of the bladder.

  • Patent number: 8801644
    Abstract: A compression garment for applying compression to a part of a wearer's body includes a flexible member, an inflatable bladder defining an inflatable chamber, and a port for communication between a source of pressurized air and the inflatable chamber. The garment also incorporates noise attenuation. The noise attenuation can include noise attenuating members on an air impingement surface of the inflatable bladder.

  • Publication number: 20110196284
    Abstract: Wound fluid blood detection systems and methods are described that are operable in conjunction with reduced pressure wound treatment (RPWT) systems, as well as ancillary therapy and monitoring systems applied concurrently with RPWT systems. The blood detection monitor operates by optically characterizing the content of wound fluids to the extent of identifying percentage blood content. This identification relies upon the transmission of select wavelengths of light across a volume of wound fluid to a photo detector (connected to signal processing instrumentation) capable of quantifying the absorption characteristics of the fluid. The detection components may be implemented in conjunction with either a fluid flow conduit (i.e. the reduced pressure tubing directing fluid away from the wound dressing) or more directly in association with the materials that comprise the wound dressing positioned within the wound bed itself.
