Abstract: A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented.

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 plurality of apertures and may be adapted to cover the tissue site. 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. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

Abstract: New and useful systems, apparatuses, and methods for providing negative-pressure therapy with instillation of topical treatment solutions are described. An apparatus may comprise an exudate container, a solution source, and a pneumatically-actuated instillation regulator. The instillation regulator may be coupled to the exudate container and to the solution source, and negative pressure from a negative-pressure source can actuate the instillation regulator. In some embodiments, a negative-pressure source may be configured for a negative-pressure interval and a venting interval, and the instillation regulator can be configured to draw instillation solution from the solution source during a negative-pressure interval and to instill the solution to a dressing during a venting interval.

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.

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 reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

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.
