Abstract
A manifold for treating a tissue site may include a first side and a second side opposite the first side. The second side of the manifold may be configured to face the tissue site, and to contract a greater amount than the first side of the manifold when exposed to a compressive force. In some illustrative examples, the manifold may be configured to distribute reduced pressure to the tissue site, and to contract when exposed to the reduced pressure. The manifold may be suitable for use with dressing assemblies, treatment systems, and methods for treating a tissue site.
Claims27
A dressing assembly configured to treat a tissue site, comprising:
- a manifold comprising a porous material configured to contract and to distribute a reduced pressure to the tissue site, the manifold further comprising a first side, a second side opposite the first side, and a thickness between the first side and the second side, the second side configured to face the tissue site;
- and
- a reinforcing member coupled at the first side of the manifold and configured to support the first side of the manifold such that the second side of the manifold is configured to contract a greater amount than the first side when the manifold is exposed to the reduced pressure, wherein at least a portion of the reinforcing member is positioned at a periphery of the first side of the manifold.
A dressing assembly configured to treat a tissue site, comprising:
- a manifold comprising a foam and configured to contract and to distribute a reduced pressure to the tissue site, the manifold further comprising a first side, a second side opposite the first side, and a thickness between the first side and the second side, the second side configured to face the tissue site;
- and
- a reinforcing member configured to support the manifold such that the second side of the manifold is configured to contract a greater amount than the first side when the manifold is exposed to the reduced pressure, wherein the reinforcing member is incorporated within at least a portion of the manifold.
A dressing assembly configured to treat a tissue site, comprising:
- a manifold configured to contract and to distribute a reduced pressure to the tissue site, the manifold further comprising a first side and a second side opposite the first side, the second side configured to face the tissue site;
- and
- a reinforcing member configured to support the manifold such that the second side of the manifold is configured to contract a greater amount than the first side when the manifold is exposed to the reduced pressure, wherein at least a portion of the reinforcing member is positioned at a periphery of the first side of the manifold.
A dressing assembly configured to treat a tissue site, comprising:
- a manifold comprising a flexible foam including a plurality of interconnected pores proximate to a first side and a second side of the manifold, the first side positioned opposite the second side and separated from the second side by a thickness of the manifold, the second side configured to face the tissue site;
- and
- a reinforcing member configured to support the manifold such that the interconnected pores proximate the second side of the manifold decrease in size more than the interconnected pores proximate to the first side of the manifold when the manifold is exposed to a reduced pressure, wherein the reinforcing member fills at least a portion of the interconnected pores proximate to the first side of the manifold.
