The connector also includes a conduit port fluidly coupling a conduit to the cavity. The connector further includes a base adjacent the cavity aperture that is configured to be positioned adjacent a drape. The cavity is configured to be fluidly coupled to a manifold through an aperture of the drape. The connector also includes a sensing probe having a proximal end configured to be fluidly coupled to the conduit and a distal end extending to the cavity aperture. The distal end is configured to be positioned adjacent to and in fluid communication with a manifold.

Abstract: A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.

Abstract: Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure. In one embodiment, a reduced-pressure dressing may include a dressing bolster, a retention pouch, and a sealing member. The dressing bolster may be adapted to apply a compressive force to the tissue site capable of closing a wound or incision therein. The retention pouch may be adapted to retain and manage fluid extracted from the tissue site to keep the tissue site substantially free of fluid and to prevent clogging of the reduced-pressure dressing. The sealing member may provide a seal over the retention pouch, the dressing bolster, and a portion of the epidermis of the patient. Other dressings, systems, and methods are disclosed.

Abstract: An apparatus, system, and method for sampling a fluid from a tissue site is described. The system includes a collection fitting, a reduced-pressure source, and a specimen container. The collection fitting includes a tee-fitting having a first arm having a first union, a second arm having a second union, and a third arm. At least one lumen extends through the tee-fitting from the first arm to the third arm, and at least one lumen extends through the tee-fitting from the second arm to the third arm. A container union is coupled to the third arm. The reduced-pressure source is configured to be fluidly coupled to the first union, and the specimen container is configured to be coupled to the container union.

Abstract: Systems, methods, and apparatuses for treating a tissue site are described, In some embodiments, the system may include a pouch having an upstream layer, a downstream layer, and an absorbent member enclosed between the upstream layer and the downstream layer. The upstream layer and the downstream layer may each include a hydrophobic side and a hydrophilic side, The hydrophilic side of both the upstream layer and the downstream layer may be positioned facing the absorbent member. The hydrophobic side of both the upstream layer and the downstream layer may form a portion of an exterior surface of the pouch such that fluid incident on the pouch is distributed laterally along the exterior surface of the pouch before being absorbed by the absorbent member.

Abstract: A collection fitting, system, and method for sampling fluid from a tissue site is described. The collection fitting includes a housing having a central passage, a first union, and a second union. The first union and the second union are in fluid communication with the central passage. The collection fitting also includes a plunger disposed in the housing and movable between a sampling position and a bypass position. The plunger includes a bypass passage configured to fluidly couple the first union and the second union through the central passage in the bypass position. The collection fitting also includes a cap having a boss configured to be inserted into the central passage. The boss includes a first inlet and a second inlet and inserts into the central passage to move the plunger. The first and second inlet fluidly couple the first union and the second union in the sampling position.

Abstract: Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure treatment device to treat a tissue site with reduced pressure may include a pump control unit fluidly separate from a collection unit. Pump energy may be provided by the pump control unit to deflect one or more diaphragms within the collection unit to create reduced pressure. Other systems, devices, and methods are presented.

Abstract: A system suitable for treating a tissue site may include an interface manifold, an interface sealing member, an absorbent layer, and a storage sealing member. The interface manifold may be positioned in fluid communication at the tissue site. The interface sealing member may be adapted to provide a sealed treatment space relative to the tissue site, and the interface manifold may be positioned in the sealed treatment space. The absorbent layer may be for positioning on an exterior facing side of the interface sealing member. The storage sealing member may be adapted to provide a sealed storage space between the storage sealing member and the exterior facing side of the interface sealing member. The absorbent layer may be positioned in the sealed storage space. Other systems, apparatuses, and methods are disclosed.

Abstract: Systems, methods, and apparatuses for providing instillation therapy with a negative-pressure source are described. The apparatus can include a housing having a dosing chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus can also include a moveable barrier disposed in the housing between the dosing chamber and the negative-pressure chamber. The housing includes a fluid inlet in fluid communication with the dosing chamber and a fluid outlet in fluid communication with the dosing chamber. The housing can also include a negative-pressure inlet in fluid communication with the negative-pressure chamber and a biasing element coupled to the moveable barrier. The biasing element is operable to move the moveable barrier between a charge position and a discharge position.
