    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: A wound dressing includes a patient interface layer, a wicking layer, an absorbent layer, and a cover layer. The patient interface layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The wicking layer, absorbent layer, and cover layer all also have a first side and a second side. A perimeter of the first side of the wicking layer is adhered to the second side of the cover layer, forming an adhesive border surrounding the wicking layer and the absorbent layer, and the wicking layer is configured to peripherally wick perspiration from underneath the adhesive border towards the center of the wicking layer and upwards towards the absorbent layer.
