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: 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.
