The present disclosure generally relates to a negative wound therapy (NPWT) system (100) comprising a mobile negative pressure device (101), a tubing assembly (105) and a non-absorbent or an absorbent dressing (104).

A compression device set includes: a compression device to be adhered to a biological surface; and a cover member attachable to and detachable from the compression device. The compression device includes: an adhesive sheet having an adhesion lower surface to be adhered to the biological surface; and a compression member fixed to an upper surface side of the adhesive sheet and configured to compress the biological surface when the adhesion surface is adhered to the biological surface. The adhesive sheet includes a first portion that is in contact with the compression member and a second portion that is not in contact with the compression member. The cover member is configured to be attached to the compression member in a state in which the cover member is configured to come into contact with an upper surface of at least a part of the second portion of the adhesive sheet.

The present invention relates to a dressing band including a sheet portion whose lower surface comes in close contact with a user's body, an adhesive portion which is applied on the lower surface of the sheet portion and attached to the body, a gauze portion which is attached to the lower surface of the sheet portion and comes in close contact with an affected area of the body, a protective film portion which is attached to a lower surface of the adhesive portion to cover the gauze portion and is separated from the adhesive portion during attachment of the sheet portion to the body, and a grip portion which protrudes from one side of the sheet portion in order to be gripped by the user and is rotatably connected to the one side of the sheet portion with respect to a fold line.

A wound monitoring and/or therapy system can include a substantially stretchable substrate supporting a plurality of electronic components, including sensors, and a plurality of electronic connections that connect at least some of the electronic components. The electronic components can also include a circuit board supporting at least one controller configured to control at least some of the sensors, the circuit board configured to operate without failure when the substrate is flexed as a result of strain. A calibration track can be positioned on the substrate and connected to a monitoring circuit configured to measure a change in resistance of the calibration track indicative of resistance change of at least some of the plurality of electronic connections. The system can include a controller with a circuit board supporting a plurality of electrical components and an antenna configured to communicate with the substrate, the antenna at least partially enclosing the circuit board.

Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a wound dressing comprising an absorbent layer comprising a plurality of portions of absorbent material that can be physically separate from each other. In some embodiments, a wound treatment apparatus can include an absorbent layer comprising a compressed portion configured to impede the flow of fluid therethrough. In some embodiments, a wound treatment apparatus can include an absorbent layer and spacer layer positioned side by side.

A system for negative pressure and hypoxic tissue therapy including a chemical pump assembly, a dressing to cover a tissue site, a plurality of hoses, and a cover layer to cover a portion of the dressing. Each hose is configured to fluidly connect the dressing to the assembly. Oxygen flows from the dressing to a reactor in the assembly where the oxygen is consumed by the reactor. The hoses have different cross-sectional areas and selectable lengths, and these can be selected to provide a desired amount of oxygen around the tissue site. The cover layer has less permeability to air that does the dressing, nd can be used to cover a portion of the dressing to inhibit the permeation of air through the dressing and thus provide the desired amount of oxygen around the tissue site.

The present invention has absorbency for the exudate of the wound surface and can maintain a moist environment suitable for promoting healing of the wound surface for a long time, an adhesive transparent multi-functional wound-covering material and a method for manufacturing the same are proposed so as not to cause pain or damage to the regenerated skin when replacing the wound dressing. Such a wound-covering material includes 14% by weight of polyvinylpyrrolidone, 5% by weight of propylene glycol, 79.0996% by weight of water, 0.6% by weight of calcium chloride, 0.3% by weight of potassium sorbate, 0.0004% by weight of RH oligopeptide, and 1% by weight of D-xylitol.

Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.
