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: A system for providing therapy to a tissue site is described. The system can include a light sensor, a motion sensor, and a controller. The controller can be communicatively coupled to the source of negative pressure, the light sensor, and the motion sensor. In some embodiments, the controller can be configured to receive a first signal from the light sensor indicative of ambient light, receive a second signal from the motion sensor indicative of activity, and activate alert based on the first signal and the second signal.

Abstract: In one example embodiment, a system for treating a tissue site with reduced pressure may include a distribution component, a negative-pressure source, and a collection vessel. The collection vessel may include a rigid canister defining a chamber. The collection vessel may also include a flexible container. The flexible container may be configured to receive fluid from the distribution component and to provide pressure communication while restricting liquid communication between an internal volume of the flexible container and the chamber of the rigid canister when the flexible container is disposed within the chamber of the rigid canister. The flexible container may include a port configured to provide the pressure communication and to restrict liquid communication between the internal volume of the flexible container and the chamber of the rigid canister. The port may include a hydrophobic filter.

Abstract: Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound, for example. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster, a comfort layer, and a polymeric enhancement layer. The dressing bolster may include foam and may have a first side and a second side. A first side of the comfort layer may be coupled to the second side of the dressing bolster, and a first side of the polymeric enhancement layer may be coupled to the second side of the comfort layer. An opposing second side of the polymeric enhancement layer may be configured to directly contact the tissue site. Other systems, dressings, apparatuses, and methods are disclosed.

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: In some examples, provided is a fluid blockage device for use with a reduced-pressure source for treating a tissue site with reduced pressure. The fluid blockage device may be configured to preclude fluid communication through a port fluidly coupled to the reduced-pressure source when the fluid blockage device contacts a liquid. Other devices, systems, and methods are disclosed.

Abstract: In one example embodiment, a wound imaging system includes a user interface, a computer processor, and an active contouring module. The user interface is configured to display an image of a wound acquired by the wound imaging system and selectively receive inputs from a user defining an initial perimeter of the wound. An active contouring module is configured to operate on the computer processor to receive the inputs defining the initial perimeter of the wound, identify features of the image on opposing sides of the initial perimeter of the wound, and identify an actual perimeter of the wound based on the initial perimeter of the wound and the identified features. The user interface is further configured to display, on the image of the wound, the actual perimeter of the wound as identified by the active contouring module and selectively receive inputs from the user to modify the actual perimeter of the wound.

Abstract: Disclosed embodiments may relate to dressings configured to provide negative-pressure wound therapy to a tissue site, while simultaneously shielding a portion of the tissue site from the negative pressure. For example, dressing assembly embodiments may comprise an outer dressing configured for applying negative-pressure wound therapy to a tissue site, and an underlying isolation patch configured for use under the outer dressing. The isolation patch may be configured to seal the portion of the tissue site so that it does not experience the negative pressure. Additionally disclosed are other apparatus, dressings, systems, and methods.
