Abstract
Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure. In one embodiment, a reduced-pressure dressing may include a dressing bolster, a retention pouch, and a sealing member. The dressing bolster may be adapted to apply a compressive force to the tissue site capable of closing a wound or incision therein. The retention pouch may be adapted to retain and manage fluid extracted from the tissue site to keep the tissue site substantially free of fluid and to prevent clogging of the reduced-pressure dressing. The sealing member may provide a seal over the retention pouch, the dressing bolster, and a portion of the epidermis of the patient. Other dressings, systems, and methods are disclosed.
Claims18
A dressing for treating a tissue site, comprising:
- a dressing bolster;
- a sealing member adapted to cover the dressing bolster and to provide a fluid seal with the tissue site;
- and
- a retention pouch positioned between the dressing bolster and the sealing member, the retention pouch comprising an absorbent core encapsulated by at least one permeable layer;
- wherein a portion of the at least one permeable layer is indented to define a gap between the sealing member and the retention pouch, and wherein the indented portion is covered by an aperture in the sealing member;
- wherein the dressing bolster and the retention pouch are adapted to move independently of each other under application of reduced pressure.
A dressing for treating a tissue site of a patient, comprising:
- a dressing bolster having a first surface and a second surface and adapted to be positioned proximate to the tissue site;
- and
- a retention pouch positioned proximate the first surface of the dressing bolster and comprising an absorbent core encapsulated by at least one permeable layer;
- wherein the retention pouch further comprises a portion where the absorbent core is removed to provide a notch;
- wherein the notch defines a recess in the at least one permeable layer, and wherein the recess defines a gap between a sealing member aperture of the sealing member and the retention pouch.
A dressing for treating a tissue site, comprising:
- a dressing bolster;
- a sealing member adapted to cover the dressing bolster and to provide a fluid seal with the tissue site;
- and
- a retention pouch positioned between the dressing bolster and the sealing member, the retention pouch comprising an absorbent core encapsulated by at least one permeable layer, wherein a portion of the at least one permeable layer is indented to define a gap between the sealing member and the retention pouch;
- wherein the indented portion is covered by an aperture in the sealing member.
