  • Patent number: 10806835
    Abstract: A method of treating a tissue site is provided. The method includes applying a reduced pressure to a tissue site with a reduced pressure source. A source pressure is monitored at the reduced pressure source, and a differential pressure is determined between the source pressure and the desired tissue site pressure. If a blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a first maximum differential pressure. If no blockage is present between the reduced pressure source and the tissue site, the differential pressure is limited to a second maximum differential pressure.

  • Patent number: 10799623
    Abstract: A method of distinguishing leak detection and canister disengagement in a reduced pressure treatment system includes monitoring an actual power level and a source pressure of a reduced pressure pump. The actual power level is compared to a target power level, and the source pressure is compared to a first alarm pressure and a second alarm pressure. A leak alarm is indicated when the actual power level is greater than the target power level and the source pressure is greater than the first alarm pressure. A canister disengaged alarm is indicated when the actual power level is greater than the target power level and the source pressure is less than the second alarm pressure.

  • Patent number: 10232155
    Abstract: A therapy device for instillation of fluid to a tissue site is described. The therapy device includes a base having a cartridge receptacle and a support coupled to the base to secure the base to a pole. The therapy device also includes a cartridge configured to engage the base when positioned in the cartridge receptacle. The therapy device also includes a pump head disposed within the cartridge receptacle and configured to engage the cartridge for movement of fluid. The cartridge includes a body forming at least a portion of a fluid reservoir and a tube segment coupled to the body and in fluid communication with the fluid reservoir. The tube segment is configured to engage the pump head.
