Abstract: New and useful systems, apparatuses, and methods for providing negative-pressure therapy with instillation of topical treatment solutions are described. An apparatus may comprise an exudate container, a solution source, and a pneumatically-actuated instillation regulator. The instillation regulator may be coupled to the exudate container and to the solution source, and negative pressure from a negative-pressure source can actuate the instillation regulator. In some embodiments, a negative-pressure source may be configured for a negative-pressure interval and a venting interval, and the instillation regulator can be configured to draw instillation solution from the solution source during a negative-pressure interval and to instill the solution to a dressing during a venting interval.

Abstract: An apparatus and system for fluidly connecting a reduced-pressure source to a dressing and a method for manufacturing and using the same include a base having an aperture and a wall having a peripheral portion coupled to the base. The wall may form a cavity in fluid communication with the aperture. The apparatus also may include a conduit port fluidly coupled to the cavity and adapted to receive a conduit. The base may be adapted to couple to the dressing, and the wall may be adapted to collapse from a first position to a second position in response to a supply of reduced pressure from the reduced-pressure source.

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: A dressing for the treatment of incisional wounds includes an upper cover, a patient interface layer, and an absorbent material. The upper cover is configured to substantially cover the incisional wound. The upper cover includes a drape and a plurality of spines coupled to the drape. The drape includes a first side and a second, wound-facing side. The patient interface layer is coupled to the second side of the drape and includes a plurality of openings that are configured to receive fluid from the incisional wound. The absorbent material is disposed between the second side of the drape and the patient interface layer.

Abstract: A system, apparatus and method for delivering negative pressure and vibrations proximate a wound site. The system comprises a dressing adapted to be fluidly coupled to the wound site and further adapted to translate vibrations to the wound site. A pad is coupled to a negative pressure source and to the dressing. The pad is also coupled to a vibration module. The system further comprises a drape covering the dressing and the pad and forming a seal between the wound site and the environment. The vibration module fluidly couples to the dressing and provides vibrations during application of negative pressure.

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 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 control device for processing the fluid data, and transmitting the data to another component in the system.
