Abstract: Sealing members and methods of manufacturing the same are described. A first film layer and a second film layer each having a first side and a second side can be provided. A first adhesive can be coupled to the second side of the first film layer to form a first adhesive layer. A second adhesive can be coupled to the second side of the second film layer to form a second adhesive layer, and a third adhesive can be coupled to the first side of the second film layer to form a third adhesive layer. One or more perforations can be formed through the third adhesive layer, the second film layer, and the second adhesive layer. A first side of the third adhesive layer can be coupled to a second side of the first adhesive layer.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. The apertures in the periphery may be larger than the apertures in the central portion. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

Abstract: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

Abstract: A dressing for treating a tissue site with negative pressure is described. The dressing includes a tissue interface and a sealing member. The dressing further includes a sealing tape configured to be coupled to the sealing member and epidermis. The sealing tape includes a bonding adhesive and a sealing adhesive coupled to a side of the sealing tape. The sealing tape includes a layer of the bonding adhesive disposed on a film layer and a layer of sealing adhesive having one or more apertures disposed on the bonding adhesive. The sealing tape can include a layer of the bonding adhesive disposed on a portion of a film layer and a layer of the sealing adhesive disposed on a uncovered portions of the film layer.

Abstract: A two-cavity pump having a single valve in one cavity and a bidirectional valve in another cavity is disclosed. The pump has a side wall closed by two end walls for containing a fluid. An actuator is disposed between the two end walls and functions as a portion of a common end wall of the two cavities. The actuator causes an oscillatory motion of the common end walls to generate radial pressure oscillations of the fluid within both cavities. An isolator flexibly supports the actuator. The first cavity includes the single valve disposed in one of a first and second aperture in the end wall to enable fluid flow in one direction. The second cavity includes the bidirectional valve disposed in one of a third and fourth aperture in the end wall to enable fluid flow in both directions.

Abstract: In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Abstract: A bodily fluid collection system may include a canister fluidly connected to a dressing at a tissue site through an inlet. The canister may also be fluidly connected to a reduced pressure source through an outlet. At least a portion of the wall of the canister may be a membrane and may have the open edge of a flexible bag container fixed to the canister surrounding the perimeter of the membrane. The flexible bag may contain an osmotic agent capable of drawing absorbent from bodily fluid in the canister through the membrane and into the flexible bag.

Abstract: The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.

Abstract: Some illustrative embodiments of an instillation assembly for treating a tissue site may include a fluid distribution lumen and a fluid hub that may define a fluid instillation pathway. The fluid distribution lumen may be defined by a first film layer and a second film layer, and the fluid hub may be positioned in fluid communication with the fluid distribution lumen. The instillation assembly may be used in combination with a reduced-pressure assembly that may define a reduced-pressure pathway separate from the fluid instillation pathway.
