An apparatus for connecting multi-lumen conduits may include a conduit adapter and a conduit collar. The conduit adapter may include a housing, a bayonet connector, and a support member connecting the housing and the bayonet connector. The support member has an aperture that permits fluid communication through the support member. One end of the conduit collar is sized for insertion into the housing, and a second end is adapted to receive a first multi-lumen conduit. The housing also is adapted to receive a second multi-lumen conduit. The bayonet connector engages a primary lumen of the first multi-lumen conduit and the second multi-lumen conduit such that the primary lumen of the second multi-lumen conduit fluidly communicates with the primary lumen of the first multi-lumen conduit. The conduit adapter and the conduit collar are capable of 360 degree rotation relative to each other about a common axis.

Systems, devices, and methods for treating a wound on a patient involve a reduced-pressure interface having an interface body that facilitates the delivery of reduced pressure to the wound and also a Coanda device that develops an airflow over a wound dressing. The airflow developed by the Coanda device enhances evaporation of liquids from the dressing. Other systems, methods, and devices are presented herein.

The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

Systems, methods, and apparatuses are presented that facilitate the provision of reduced pressure to a tissue site by using a delivery-and-fluid-storage bridge, which separates liquids and gases and provides a flow path for reduced pressure. In one instance, a delivery-and-fluid-storage bridge includes a delivery manifold for delivering reduced pressure to a treatment manifold at the tissue site and an absorbent layer proximate the delivery manifold adapted to receive and absorb liquids. The delivery manifold and the absorbent layer are encapsulated in an encapsulating pouch. A first aperture is formed proximate a first longitudinal end of the delivery-and-fluid-storage bridge for fluidly communicating reduced pressure to the delivery manifold from a reduced-pressure source, and a second aperture is formed on a patient-facing side of the delivery-and-fluid-storage bridge. Reduced pressure is transferred to the tissue site via the second aperture. Other systems, apparatuses, and methods are disclosed.

A system for treating a tissue site of a patient includes a dressing filler adapted to be positioned at the tissue site. The dressing filler is comprised of a porous substrate having at least one compressed region and at least one expanded region. The compressed region of the porous substrate is held in a compressed state by a first coating capable of dissolving in the presence of a fluid, and the expanded region of the porous substrate is held in an expanded state by, a second coating.

Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.
摘要:
A system for treating a tissue site of a patient includes a dressing filler adapted to be positioned at the tissue site. The dressing filler includes a base and a plurality of nodes extending from the base. The base further includes a plurality of openings disposed in the base. At least one of the plurality of nodes is comprised of a non-tactile-stimulus-activated, macroscopically-deforming (NTSAMD) material.
摘要:
A reduced-pressure treatment system for debriding a treatment area of a tissue site and applying reduced pressure is disclosed. The reduced-pressure treatment system includes a hydrogel having a blocked acid debriding agent. The hydrogel is adapted to cover the treatment area and enhance autolytic debridement at the treatment area. The reduced-pressure treatment system includes a manifold that is adapted to cover the hydrogel and distribute reduced pressure to the tissue site. The reduced-pressure treatment system also includes a sealing drape for forming a fluid seal over the tissue site and manifold. Other systems, methods, and dressings are presented.
摘要:
Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods involve a sealed wound dressing assembly that helps form a fluid seal around the linear wound while simultaneously encompassing a subcutaneous delivery conduit to deliver fluid to or from a subcutaneous tissue site. In one instance, a reduced-pressure interface is used to allow the subcutaneous delivery conduit to pass through tissue at or near the linear wound and through a wound dressing assembly to a drainage receptacle.
摘要:
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.
