Abstract: In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

Abstract: Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.

Abstract: A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

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: A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.

Abstract: Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise positioning a dressing interface having a pH sensor, a temperature sensor, a humidity sensor, and a pressure sensor at a tissue site, and applying reduced pressure to the dressing interface to draw fluids from the tissue interface in contact with the sensors to sense the pH, temperature, humidity, and pressure properties of the fluids flowing from the tissue site. The method may further comprise providing fluid data indicative of such properties to a processing element for processing the fluid data, and transmitting the data to another component in the system.

Abstract: An indicator configured to be attached to a wound dressing includes first and second parts. The wound dressing is configured to collapse in response to an applied negative pressure. The first and second indicator parts are configured to move relative to one another as the wound dressing is collapsed. The movement of the first and second indicator parts is configured to allow a user to easily visualize the compression of the wound dressing and monitor the application of the negative pressure to the wound dressing. A marker is provided along a top surface of the first part and a window is formed on the second part. The changes in the portion of the marker that is visible in the window as the first part is slid into or under the second part are configured to provide for easier detection of the collapse of the wound dressing by the user.
