Abstract: A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

Abstract: A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.

Abstract: A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

Abstract: A release liner, for example for use with a tissue cover having a first adhesive and a second adhesive, may comprise a first release agent adapted for the first adhesive and a second release agent adapted for the second adhesive. Typically, the first release agent is different from the second release agent, and the first release agent may be configured to interact with a first area of the cover having the first adhesive, and the second release agent may be configured to interact with a second area of the cover having the second adhesive. In some embodiments, the release liner may be multi-layered, for example with a first layer comprising the first release agent and a second layer comprising the second release agent. Some such embodiments may have perforations through the second layer of the release liner, with the first layer then being disposed with respect to the second layer in such a way as to expose the first release agent through the perforations in the second layer.

Abstract: This disclosure describes devices, systems, and methods related to a compound film. An exemplary compound film includes a first layer including a first polymer composition including polyurethane and a second layer including a second polymer composition removably coupled to the first layer. The compound film further includes light switchable adhesive coupled to the second layer and configured to transition from a first state to a second state, the light switchable adhesive has a first peel strength in the first state that is greater than a second peel strength of the light switchable adhesive in the second state. A third peel strength between the first layer and the second layer is less than the second peel strength between the light switchable adhesive in the first state and a bond site.

Abstract: A system for applying reduced pressure to tissue includes a multi-lumen reduced pressure delivery tube having a proximate end, a distal end, a primary lumen extending through the conduit from the proximate end to the distal end, and an ancillary lumen extending through the conduit from the proximate end to the distal end. A vacuum pump is coupled to the proximate end of the primary lumen, and a reduced pressure adapter is coupled to the distal end of the reduced pressure delivery tube. The adapter includes channels to direct liquid away from the ancillary lumens and into the primary lumen.

Abstract: A system is described herein that can irrigate a tissue site using negative-pressure. The system may include a tissue interface configured to be placed adjacent to the tissue site, and a sealing member configured to be placed over the tissue interface to form a sealed space. The system may also include a negative-pressure source configured to be fluidly coupled to the sealed space and a fluid source. The system may further include an irrigation valve. The irrigation valve can have a fluid inlet configured to be fluidly coupled to the fluid source. The irrigation valve can also have a fluid outlet configured to be fluidly coupled to the sealed space. The irrigation valve may also include a clamp configured to be actuated by the negative-pressure source to regulate fluid flow from the fluid source through the fluid outlet.
