Abstract: Aspects include a negative pressure wound therapy system and methods for manufacturing a negative pressure wound therapy system. The system comprises a dressing configured to be positioned on a wound site, a hub configured to have aspirational attachment to the dressing, and a pressure engine pre-evacuated to a sub-atmospheric pressure and configured to have aspirational attachment the hub such that the pressure engine is configured to aspirate fluid away from the dressing via a fluid channel extending from the dressing, through the hub, to the pressure engine. Sub-atmospheric pressure in the pressure engine can be achieved by evacuating air from and then sealing the pressure engine, forming the pressure engine in a sub-atmospheric pressure environment and then sealing the pressure engine, or forming the pressure engine in a first environment at sub-atmospheric pressure relative to a second environment and moving the pressure engine to the second environment for use.

Abstract: A negative pressure dressing assembly includes a drape including an aperture, a cover assembly selectively sealing the aperture in an air-tight manner, a reactor configured to react with a selected gas, and a sealing liner that forms a breakable seal that prevents the reactor from being exposed to the selected gas. The drape is applied to skin to form an enclosed volume between the drape and the skin. The reactor is configured to be activated by breaking the seal, and to be put into fluid communication with the enclosed volume to consume the selected gas from the enclosed volume to create a negative pressure in the enclosed volume.

Abstract: A controlled oxygen dressing includes a flexible drape that is selectively permeable to air and is adhere to skin to define a first volume around a tissue site. A cover layer, impermeable to air, is sealed to the drape to thereby define a second volume between the cover layer the drape. An oxygen scavenger is arranged in the second volume and consumes oxygen in the second volume, which produces an oxygen concentration differential between the first and second volumes, This differential causes oxygen to diffuse through a covered portion of the drape, from the first volume to the second volume, thus decreasing the amount of oxygen in the first volume. Oxygen entering into the first volume from the surrounding environment diffuses through a non-covered portion of the drape. Therefore, an area of the cover layer can be selected to produce a desired level of oxygen in the first volume.

Abstract: 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.

Abstract: A device for tissue treatment includes a drape configured to seal to skin of a patient to define a substantially air-tight enclosed volume around a tissue site. The drape includes an aperture extending through the drape and thus provides access to the enclosed volume. The device also includes a valve assembly attached to the drape, covering the aperture, and regulating a flow of air through the aperture. The valve assembly includes a base, an optional valve arranged in the base and configured to open to allow air to flow through the aperture, and to close to restrict air from flowing through the aperture, a top that is moveable with respect to the base between an opened position and a closed position, and a seal arranged on the top, and scaling to the base over the aperture and optional valve when the top is in the closed position.

Abstract: Embodiments of a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.
