摘要： A system for subatmospheric pressure therapy in connection with healing a wound is provided. The system includes a wound dressing cover dimensioned for positioning relative to a wound bed of a subject to establish a reservoir over the wound bed in which subatmospheric pressure may be maintained, a subatmospheric pressure mechanism including, a housing, a vacuum source disposed in the housing, and a collection canister in fluid communication with the vacuum source. The system further includes an exudate conduit in fluid communication with the wound dressing and the collection canister for collecting exudate removed from the reservoir and deposited in the collection canister under influence of the vacuum source and a vent conduit in fluid communication with the collection canister and the wound dressing for introducing air into the reservoir to facilitate flow of exudate through the exudate conduit.

摘要： A reduced-pressure system for treating a tissue site on a patient includes a distribution manifold that adheres to a tissue site to allow retention without external support. The distribution manifold includes a porous member and a tissue-fixation element. The tissue-fixation element maintains the porous member substantially adjacent to the tissue site while a sealing member is applied. In one instance, the tissue-fixation element is a soluble adhesive that partially covers either the tissue-facing side of the porous member or a tissue-facing side of a fluid-permeable substrate layer that is on the tissue-facing side of the porous member. Other systems, distributions manifolds, and methods are presented.

摘要： A penile condom catheter facilitates urine collection and egress of urinary fluids away from the body torso. A circumferential anchoring structure includes a web of flexible strands sized and arranged to at least partially contact a portion of the penis. The anchoring structure provides a flexible yet secure hold against the penis when flaccid and provides an increase in the hold when a longitudinal force is exerted upon the anchoring structure. An annularly circumferential penile skin covering material is affixed to the anchoring structure and sized to fit over at least a portion of the penis. A seal is affixed to at least a portion of a covering material, a covering material orifice, or an anchoring structure. A conduit is affixed to at least one of a covering material, a covering material orifice, a seal and an anchoring structure created to permit the flow of urinary fluid away.

摘要： A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

摘要： A negative pressure wound therapy system treats multiple wounds on a patient's body. The system includes a source of negative air pressure, an air source, first and second fluid collection volumes, first and second wound-covering domes disposed over first and second wounds, a valve assembly disposed between the source of negative air pressure and the first and second fluid collection volumes, and between the air source and the first and second domes. The valve assembly has first and second operational modes. In the first, the valve assembly puts the source of negative air pressure in fluid communication with the first fluid collection volume, and the air source in fluid communication with the first dome. In the second, the valve assembly puts the source of negative air pressure in fluid communication with the second fluid collection volume, and the air source in fluid communication with the second dome.

摘要： Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

摘要： A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port.

摘要： 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.

摘要： A wound care bandage for treating a wound is provided. The bandage includes an SIS layer to be placed on the wound surface and a cover to be placed over the wound. The bandage further includes a structure to provide a vacuum space. A method for promoting wound healing is further provided. The method includes applying the above-mentioned wound care bandage to the wound and creating a vacuum in the vacuum space to draw blood controllably from the wound into the SIS layer.
