Abstract: A disc pump includes a pump body having a cavity for containing a fluid. The disc pump also includes an actuator adapted to hold an electrostatic charge to cause an oscillatory motion at a drive frequency. The disc pump further includes a conductive plate positioned to face the actuator outside of the cavity and adapted to provide an electric field of reversible polarity, the conductive plate being electrically associated with the actuator to cause the actuator to oscillate at the drive frequency in response to reversing the polarity of the electric field. The disc pump further includes a valve disposed in at least one of a first aperture and a second aperture in the pump body. The oscillation of the actuator at the drive frequency causes fluid flow through the first aperture and the second aperture when in use.

Abstract: A low-profile dressing interface or connector may comprise at least two side-by-side fluid pathways fluidly coupled to a recessed space of the connector, one for providing negative pressure to a tissue interface and the other for sensing negative pressure within the recessed space adjacent the tissue interface. The apparatus may comprise a top layer having a plurality of closed cells with tapered sidewalls. The apparatus may also comprise a base layer forming a sealed space between the top layer and the base layer. The base layer may further include a plurality of closed cells having tapered sidewalls. The apparatus may then further comprise a barrier coupled between the top layer and the base layer to form two fluid pathways within the sealed space.

Abstract: Apparatuses and dressing components for tissue treatment with negative pressure and methods of making and using the dressings and dressing components are disclosed. For example, an apparatus for managing fluid from a tissue site may comprise at least two fluid pathways formed along the length of the apparatus. The apparatus may have at least one hinge line spanning along the length of the apparatus between at the at least two fluid pathways, and the apparatus may be curved about the hinge line. Some examples of the apparatus may comprise multiple layers assembled in a stacked relationship, which may be bonded together using weld lines to define at least two fluid pathways along the length of the apparatus. In some examples, the apparatus may be curved about the weld lines.

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: Wounds dressings, systems, and methods are presented that involve using a patient's body heat to enhance liquid removal from the wound dressing through a high-moisture-vapor-transmission-rate drape. Additional heat sources or devices, such as nano-antennas or electrical heating elements, may be added or used separately to enhance the removal liquid from the wound dressing. Other dressings, systems, and methods are presented herein.

Abstract: Systems, methods, and apparatuses for providing installation therapy and negative-pressure therapy are described. The apparatus includes a housing and a moveable barrier disposed in the housing to form a dosing chamber and a pressure chamber. The apparatus also includes a therapy conduit configured to be fluidly coupled to a pressure source and to a canister. The apparatus further includes a fluid inlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a fluid source and a fluid outlet fluidly coupled to the dosing chamber and configured to be fluidly coupled to a dressing. A pressure inlet is fluidly coupled to the therapy conduit and the pressure chamber; and a check valve is disposed in the therapy conduit.

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.

Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.

Abstract: A reduced pressure tissue treatment system includes an applicator having an aperture, a first pad section, and a second pad section substantially covering the aperture and positioned substantially adjacent the first pad section. A fabric layer is located at least partially between the second pad section and the drape, and the fabric layer includes a woven or non-woven fabric made from a fiber material. A drape substantially covers the first pad section, the second pad section, the fabric layer, and the applicator. A reduced pressure source is in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.
