Abstract: An apparatus for applying negative pressure to a tissue site of a patient may include a tissue interface, a cover, an aperture in the cover, and a sealing member. The tissue interface may have an anatomical shape configured to cover the tissue site. The cover may be configured to cover the tissue interface. The aperture in the cover may be fluidly coupled to the tissue interface. The sealing member may be configured to seal the cover to the patient, wherein the cover and the sealing member are configured to cooperate to form a sealed chamber containing the tissue interface. The tissue interface may be coupled to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site. The source of negative pressure may be coupled to the cover of the apparatus.

Abstract: A dressing for treating a tissue site with negative pressure including a tissue interface, a cover, a chamber wall, and a base. The cover may be adapted to be sealed to epidermis proximate the tissue site. The chamber wall may define a pump chamber, wherein the pump chamber may be adapted to be fluidly coupled to the tissue interface. The base may extend from the chamber wall, wherein the base may be fluidly sealed to the cover. The dressing may include an intake valve and an exhaust valve fluidly coupled to the pump chamber. The pump chamber may be compressed to evacuate fluid from the pump chamber through the exhaust valve. The pump chamber may then be expanded to draw′ fluid through the intake valve from the tissue interface. This supplies a negative pressure to the tissue interface which may be adapted to distribute negative pressure across the tissue site.
