Abstract: Systems, apparatuses, and methods for instilling fluid to a tissue site in a negative-pressure therapy environment are described. Illustrative embodiments may include a pneumatically-actuated instillation pump that can draw a solution from a solution source during a negative-pressure interval, and instill the solution to a dressing during a venting interval. A pneumatic actuator may be mechanically coupled to a disposable distribution system that can provide a fluid path between the solution source and a distribution component. A bacterial filter may be disposed in the fluid path between the actuator and the distribution component to prevent contamination of the actuator during operation. The distribution system may be separated from the actuator and disposed of after operation, and the actuator may be re-used.

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 or apparatus may include a container configured to collect fluid from a tissue site and regulate negative-pressure from a negative-pressure source. In some embodiments, the container may include a regulator that receives negative pressure directly from an unregulated negative-pressure source, such as a wall-suction outlet. The regulator may regulate down the pressure delivered to a collection chamber in the container, which may in turn be connected to a tissue site.

Abstract: This disclosure includes wound dressings and systems with low-flow, high-concentration therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; a sorbent material configured to be disposed above or below the manifold and to capture exudate; and a gas-occlusive layer configured to be disposed over the manifold and the sorbent material and coupled to the tissue such that an interior volume containing the manifold and the sorbent material is defined between the gas-occlusive layer and the tissue and the gas-occlusive layer limits escape of therapeutic gas from the interior volume.

Abstract: An apparatus and method for managing reduced pressure at a tissue site are disclosed. The apparatus comprises a pump for supplying reduced pressure to the tissue site, a motor coupled to the pump to propel the pump, and a drive system electrically coupled to the motor that includes a power source that provides a source of direct current power to the motor during an operational period at a substantially constant current and of sufficient magnitude to supply a targeted reduced pressure during the operational period. The drive system also includes a controller that monitors the pump's loading on the motor by measuring the voltage across the motor to determine whether the motor voltage remains within a predetermined operational range of voltages necessary for maintaining the reduced pressure supplied by the pump proximate to the targeted reduced pressure without directly measuring the reduced pressure using a pressure sensor.

Abstract: In some illustrative embodiments, a system suitable for treating a tissue site may include a dressing, a low-profile conduit, a conduit interface, and a reduced-pressure source. The dressing may be adapted for positioning at the tissue site. The low-profile conduit may be adapted for fluidly coupling to the dressing. The low-profile conduit may include a manifold and a sealing member encapsulating the manifold. The conduit interface may be adapted for fluidly coupling to the low-profile conduit. The conduit interface may be in fluid communication with the dressing through the low-profile conduit. The reduced-pressure source may be adapted for fluid communication with the conduit interface. Other systems, devices, and methods are disclosed.

Abstract: A reduced pressure treatment system includes a liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied. The canister includes a first space configured to collect the liquid from the tissue site and a filter having a frame and a non-planar filter element. The filter defines a second space within the canister separated from the first space by the filter element. The filter element substantially prevents liquid from passing from the first space into the second space. The filter element substantially allows gaseous communication between the first space and the second space when the second space is exposed to a reduced pressure.

Abstract: Manifold structures, systems, and methods are disclosed that include using longitudinal members and one or more shaped projections to cause microstrain at a tissue site. In one instance a manifold structure includes a plurality of spaced longitudinal members and at least one shaped projection coupled to at least one of the plurality of longitudinal members for creating a microstrain at a tissue site. The at least one shaped projection includes a columnar member having a distal end and includes an enlarged member positioned at the distal end of the columnar member. The columnar member has a first outer diameter (D1) and the enlarged member has a second outer diameter (D2). The second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D2>D1). Other systems, methods, and structures are presented.

Abstract: An inline storage-and-liquid-processing pouch for use with body fluids from a patient is presented that involves introducing body fluids into a first chamber in the storage-and-liquid-processing pouch and flowing air through a second chamber. The chambers are separated by a high-moisture-vapor-transfer-rate member. The air flow in the second chamber enhances liquid removal from the first chamber across the high-moisture-vapor-transfer-rate member. Other systems, devices, and methods are disclosed herein.
