Abstract: A customizable wound treatment system for treating multiple zones of a wound includes a dressing configured for use with a first zone and a second zone of a wound that includes a first foam layer placed over the first zone, a second foam layer placed over the second zone, a first drape layer disposed over the first foam layer and beneath the second foam layer, and a second drape layer disposed over the second foam layer. The customizable wound treatment system includes a negative pressure source pneumatically coupled to the first foam layer and the second foam layer and operable to create a negative pressure at the first zone and the second zone and a fluid instillation pump fluidly coupled to the first foam layer and configured to instill a treatment fluid to the first zone.

Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.

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: Systems and methods for providing negative-pressure therapy with fluid instillation therapy and, more specifically, scheduling and controlling both the negative pressure therapy and the fluid instillation therapy are described. The method may comprise applying negative pressure to the dressing based on an initial therapy configuration, and monitoring negative pressure parameters associated with the application of negative pressure to the dressing to identify negative pressure alarm conditions. The method may further comprise applying instillation fluid to the dressing based on the initial therapy configuration, and monitoring instillation parameters associated with the application of instillation fluid to the dressing to identify instillation alarm conditions. Both may include modifying the initial therapy configuration to generate a modified therapy configuration in response to the negative pressure and instillation alarm conditions identified.

Abstract: A releasable connector for a negative pressure wound therapy system having a drape and a tube includes a base and a tube fitting. The base is configured to be coupled to the drape such that a substantially air-tight seal is formed between the base and the drape. The base includes a base locking member. The tube fitting is configured to be coupled to the tube such that a substantially air-tight seal is formed between the tube fitting and the tube. The tube fitting includes a tube locking member. The tube fitting is further configured to be selectively coupled to the base through an interaction between the tube locking member and the base locking member such that a substantially air-tight seal is formed between the tube fitting and the base.

Abstract: A wound therapy system includes a single conduit fluidly connecting a wound site to a. removed fluid canister. A negative pressure circuit is defined by the wound site, the conduit, the removed fluid canister and tubing extending between the removed fluid canister and a pneumatic pump that applies negative pressure to the negative pressure circuit. A method of operating the wound therapy system includes profiling and benchmarking pressure decay within the negative pressure circuit against previous and/or expected pressure decay to identify any new or sudden anomalies that occur during the operation of the wound therapy system. The wound therapy system may additionally alert a user to such anomalous operation of the wound therapy system and/or identify and alert a user to an underlying cause (e.g, blockage and/or leak, etc.) that is responsible for the anomalous readings.

Abstract: In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

Abstract: An apparatus for treating a tissue site comprising a negative-pressure source configured to be fluidly coupled to the tissue site; an instillation source configured to be fluidly coupled to the tissue site; and a controller operatively coupled to the negative-pressure source and to the instillation source. The controller can be configured to operate the negative-pressure source and the instillation source to intermittently deliver negative pressure to the tissue site for a negative-pressure interval and deliver instillation fluid to the tissue site for an instillation interval. A purge volume of instillation fluid may be delivered to the tissue site at a purge frequency. In some examples, the purge volume may be delivered through the second fluid conductor and removed through the first fluid conductor during a negative-pressure interval.
