    Abstract: This disclosure describes devices, systems, and methods related to two-piece dressings. In one aspect, a two-piece dressing includes a drape including a first light switchable adhesive, and a pad. The pad includes a second light switchable adhesive configured to couple the pad to the drape and a light source configured to emit light and activate at least the second light switchable adhesive. In another aspect a two-piece dressing includes a drape and a pad. The pad is configured to be coupled to the drape and to a light source, and the pad includes a light switchable adhesive configured to couple the pad to the drape. The light source is configured to emit light to activate the light switchable adhesive to decouple the pad from the drape, and the pad is configured to direct the light to activate second light switchable adhesive to decouple the drape from a tissue site.

    Abstract: Systems, apparatuses, and methods for providing negative pressure to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure to a tissue site that can be used in conjunction with sensing properties of fluids extracted from 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 an ambient port for providing the pressure sensor and the humidity sensor with access to the ambient environment providing readings relative to the atmospheric pressure and humidity.

    Abstract: A system for negative-pressure therapy is described. The system includes a dressing configured to be positioned adjacent a tissue site and a piezoelectric pump having at least one inlet and at least one outlet. An adapter is coupled to the piezoelectric pump and configured to be fluidly coupled to the dressing. The adapter is configured to aggregate fluid flow into the at least one inlet. The adapter can have a block. A first recess depends into the block, and a second recess depends into the block from the first recess, the second recess having an area less than the area of the first recess. A bore depends through the block from the second recess to the first side, and a conduit is coupled to the first side and fluidly coupled to the bore.

    Abstract: A system for applying negative-pressure therapy to an abdominal cavity. The system comprises: a tissue interface comprising a first contact layer and a second contact layer, each of the first contact layer and the second contact layer having perforations formed therein. The system also comprises a spacer layer disposed between the first contact layer and the second contact layer, the spacer layer configured to extend to different zones within the abdominal cavity. The system also includes a first sensor associated with the spacer layer and configured to acquire data associated with fluid at a first zone within the abdominal cavity and a first wireless transceiver associated with the first sensor and configured to transmit the data to an external therapy control device.

    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. In one example embodiment, a system for providing negative-pressure and instillation to a tissue site may comprise a negative-pressure device and an instillation device. The negative-pressure device may comprise a negative-pressure source and a controller electrically coupled to the negative-pressure source. The instillation device may comprise a dosing valve having a dosing chamber including a dosing outlet configured to be fluidly coupled to a fluid port and a dosing inlet configured to be fluidly coupled to a source of instillation solution. The dosing valve may also have a working chamber including a biasing element operably engaged to the dosing chamber and configured to be fluidly coupled to the negative-pressure source. In some embodiments of the system, the instillation device may further comprise a wireless transceiver configured to communicate with the controller, and at least one sensor coupled to the wireless transceiver to provide a signal indicative of an operating condition of the dosing valve, and wherein the wireless transceiver is configured to communicate the at least one signal to the controller.

    Abstract: A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway.
