Wound cleansing apparatus

摘要

An apparatus for cleansing and promoting tissue growth in wounds, in which irrigant fluid optionally containing cell nutrients and/or other physiologically active material 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, a biodegradable scaffold in contact with the wound bed and a means for fluid cleansing and back to the dressing. The apparatus has means for supplying thermal energy to the fluid in the wound. 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 dressing and a method of treatment using the apparatus.

主权项

1. An apparatus for treatment of a wound, comprising:
a member comprising a plurality of flow channels, the member being positionable over or within a wound;
wherein:
each of the plurality of flow channels defines a flow path that is separate along its length from the flow paths defined by each of the other of the plurality of flow channels;the plurality of flow channels are interconnected only at a center portion of the member;each of the plurality of flow channels extends in a radial direction from a center portion of the member; a relatively liquid impermeable backing layer configured to be disposed over the member and capable of forming a relatively fluid-tight seal or closure over a wound; and a conduit having an end portion configured to be mounted above the center portion of the member, the conduit being in fluid communication with each of the flow paths when the end portion of the conduit is mounted above the center portion of the membrane.
