Abstract: A cover for protecting a tissue site may comprise a shell layer, an adhesive disposed on the shell layer, and a contact layer disposed adjacent to the adhesive. The contact layer may have a first pattern of apertures and bridges, and the shell layer may have a second pattern of apertures overlaying the bridges. In some examples, the adhesive may have a bond strength that is greater than the tensile modulus of the shell layer. The contact layer may have an open area of about 40 percent to about 50 percent of the total area of the contact layer. A release liner may be disposed adjacent to the contact layer. Perforations through the shell layer and the contact layer can define a sacrificial segment configured to be separated from the shell layer and the contact layer. A handling bar may be coupled to the sacrificial segment.

Abstract: A system or apparatus including a dressing, a dressing interface, and a humidity sensor may be suitable for use with systems and methods for treating a tissue site. Embodiments of the apparatus are provided for treating a tissue site with reduced pressure provided by a source of reduced pressure. The dressing may include abase layer, a sealing member disposed proximate the base layer to define an enclosure providing a sealed space over the tissue site, and an absorbent member disposed within the enclosure. The dressing interface may comprise a reduced-pressure port configured to be coupled to the source of reduced pressure and a therapy port covered by a hydrophobic filter defining a reduced-pressure pathway between the hydrophobic filter and the source of reduced pressure. The humidity sensor may comprise a sensing portion fluidly coupled to the reduced-pressure pathway and an output for providing a humidity signal that indicates the amount of fluid extracted from the tissue site and stored by the absorbent member. Other dressings, systems, and methods are disclosed.

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 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 dressing interface for connecting a negative-pressure source to a dressing may have a coupling member comprising an aperture, a first adhesive region having a first region peel strength, and a second adhesive region having a second region peel strength less than the first region peel strength. The dressing interface may further have a flange coupled to the coupling member, and a conduit housing coupled to the flange and extending through the aperture in the contact layer.

Abstract: A dressing for treating a tissue site, which may comprise a tissue interface and a cover comprising an expansion zone configured to be disposed over the tissue interface. The tissue interface may comprise a tissue contact layer having a treatment aperture in some examples. In more particular examples, the cover may be coupled to the tissue contact layer to form an expansion chamber between the expansion zone and the tissue contact layer. The cover may also comprise a base coupled to the tissue contact layer in some examples. Additionally, the tissue interface may further comprise an absorbent disposed within the expansion chamber in some embodiments. In some examples, the absorbent may be a manifold. Additionally or alternatively, the expansion chamber and the absorbent may be detachable.

Abstract: Systems, methods, and apparatuses for regulating the delivery of negative-pressure therapy are described. The system includes a negative-pressure source, an energy source, and a switch. The switch can include a first conductor electrically coupled to the negative-pressure source, a second conductor electrically coupled to the energy source, and a diaphragm having a first position electrically coupling the first conductor to the second conductor and a second position separated from the first conductor and the second conductor. The diaphragm is configured to move between the first position and the second position in response to a differential between a control pressure and a therapy pressure.

Abstract: In some examples, a system for treating a tissue site may include a dressing, at least one fluid sampling conduit, and at least one fluid sampling assembly. The dressing may be configured to be positioned at the tissue site. The at least one fluid sampling assembly may be configured to be in fluid communication with the tissue site through the at least one fluid sampling conduit. The at least one fluid sampling assembly may include a fluid vessel for receiving a fluid from the tissue site. The fluid may be a sampling fluid communicated directly from the tissue site and representative of the physiological condition of the tissue site. Other devices, systems, and methods are disclosed.

Abstract: A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a plurality of apertures and may be adapted to cover the tissue site. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

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.
