Wound cleansing apparatus with stress
First Claim
1. An apparatus for irrigating, stressing and/or cleansing wounds, comprising:
- a fluid flow path comprising;
a conformable wound dressing, comprising;
a backing layer which is capable of forming a relatively fluid-tight seal or closure over a wound;
an inlet conduit passing through and/or under a wound-facing face of the dressing and directly or indirectly communicating with at least a fluid reservoir; and
an outlet conduit passing through and/or under the wound-facing face;
wherein a relatively fluid-tight seal or closure is formed over the wound at the point at which the inlet conduit and the outlet conduit passes through and/or under the wound-facing face;
a means for fluid cleansing in direct or indirect communication at least with the outlet conduit, the means for fluid cleansing being configured to retain in the cleansed fluid nutrients, molecules, factors, and/or other components from the wound exudate that aid in proliferation or that are favorable to the wound healing;
a fluid recirculation tube for directing cleansed fluid from the means for fluid cleansing back into the inlet conduit so that nutrients, molecules, factors, and/or other components from the wound exudate that aid in proliferation or that are favorable to the wound healing process are returned to the wound; and
a device for moving fluid through the wound dressing and means for fluid cleansing; and
means for stressing the wound bed comprising means for bleeding fluid into the flow path to vary the pressure applied to the wound to stress the wound.

Abstract
An apparatus for cleansing wounds with means for stressing the wound bed and optionally tissue surrounding the wound, in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The means for stressing the wound bed and optionally tissue surrounding the wound promotes wound healing. The dressing and a method of treatment using the apparatus.
