摘要： A barrier for use in negative pressure wound therapy can include a base layer and surface structures. The barrier can be used to reduce or prevent tissue ingrowth. A method of using a negative pressure wound therapy system can include positioning a perforated barrier in a wound. After positioning the perforated barrier in the wound, positioning a pad in the wound on top of the perforated barrier, positioning a seal on top of the wound to at least partially seal the perforated barrier and the foam in the wound, and applying negative pressure wound therapy to the wound.

摘要： Systems, apparatuses, and methods for providing negative pressure with 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, a system may comprise a tissue interface adapted to be coupled to a source of instillation fluid and a dressing interface having a therapy cavity that includes a pH sensor to provide data indicative of acidity/alkalinity at the tissue site. Such apparatus may further comprise algorithms for processing such data for providing information relating to the progression of healing of wounds at the tissue site.

摘要： A filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, the passageway configured to permit passage of a fluid in a first direction defined by the inlet and the outlet; and a filter disposed within the passageway and oriented to define a volumetric direction that is different than the first direction. Another filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, and a filter disposed within the passageway, wherein the filter comprises a gelling absorbent material that, when in a dry state, is permeable to gas and that, when contacted by an aqueous fluid, converts to a gel. Such filter adaptors may be used for negative pressure wound therapy, dressing, or as syringe filters.

摘要： A negative pressure wound therapy device can include one or more fluid detection systems. A canister fluid level detection system can incorporate various fluid detection devices to communicate data relating to the fluid level of the canister. In some cases, a negative pressure wound therapy device can include a device housing, a negative pressure source, and a canister configured to be in fluid communication with the negative pressure source. The canister can include a canister housing configured to store fluid aspirated from a wound, a cap connected to the canister housing, and a fluid level sensor supported by the cap. The fluid level sensor can be configured to detect a completed electrical circuit when the fluid aspirated from the wound comes into contact with the sensor. An electronic circuitry can be configured to detect a state of the sensor and provide an indication of a status of the canister.
