  • Patent number: 11806469
    Abstract: A housing of a pump unit is fixed to a drape of a wound dressing by a joint portion. A suction chamber that is brought into a negative pressure by driving of a piezoelectric pump directly communicates with a closed space through an opening and an inlet. Hence, a therapy device does not need to include a pipe that allows the closed space and the pump unit to communicate with each other. Therefore, since the therapy device does not need to include the pipe that allows the pump unit to communicate with the closed space, detachment of the pump unit from the wound dressing owing to coming-off of the pipe is avoided. Since the housing is fixed to the drape by the joint portion, the pump unit can be prevented from detaching from the wound dressing.

  • Patent number: 11432967
    Abstract: Disclosed embodiments may relate to devices, systems, and methods for providing negative-pressure therapy simultaneously to a plurality of tissue sites using a single negative-pressure source. For example, a fluid bridge may comprise a plurality of distal ends, each configured to interact fluidly with a tissue site. In some embodiments, each distal end may have an aperture. The bridge may also comprise a port for entry of negative pressure into the enclosed space of the bridge. In some embodiments, each distal end may comprise a one-way valve. The enclosed space of the fluid pathway between the distal ends and the port may be supported in some embodiments, to prevent collapse due to negative pressure and/or compression.

  • Patent number: 11291758
    Abstract: A fluid collection system includes a vacuum source, a collection vessel, and a surgical drape. A fluid outflow line is connected between the surgical drape and the collection vessel. The fluid outflow line provides a path for fluid to the collection vessel. A suction line is connected with the collection vessel. The suction line provides suction to draw fluid through the fluid outflow line to the collection vessel. The suction line branches into a first suction line and a second suction line parallel with the first suction line. The first suction line and the second suction line are each connected with the vacuum source. A flow restrictor is disposed along the first suction line. A valve is disposed along the second suction line. The valve is opened in a pulsatile fashion when fluid is present in the surgical drape to increase a level of suction provided to the surgical drape.

  • Patent number: 11266821
    Abstract: A system and method for providing fluid to a tissue site is described. The method fluidly couples an instillation therapy system to the tissue site and monitors a pressure supplied to the tissue site by a reduced-pressure source with the instillation therapy system for a time period. The method provides fluid to the tissue site with the instillation therapy system in response to the pressure at the tissue site during the time period. The system includes a pressure sensor fluidly coupled to the tissue site to measure a pressure proximate the tissue site. A valve and a flow meter are fluidly between a fluid reservoir and the tissue site. A controller is communicatively coupled to the pressure sensor and the valve and configured to monitor the pressure at the tissue site and a volume of fluid flow to the tissue and, in response, operate the valve.
