APPARATUS WITH ACTIVES FROM TISSUE
First Claim
1. According to the present invention there is provided an apparatus for aspirating, irrigating and/or cleansing wounds, comprisinga) a fluid flowpath, comprisingi) a wound dressing, having a backing layer and at least one inlet pipe for connection to a fluid supply tube, which passes through and/or under the backing layer and at least one outlet pipe for connection to a fluid offtake tube, which passes through and/or under the backing layer, at least one inlet pipe being connected to a fluid recirculation tube, and at least one outlet pipe being connected to a fluid offtake tube;
- andii) a means for fluid cleansing having at least one inlet port connected to a fluid offtake tube and at least one outlet port connected to a fluid recirculation tube;
b) a device for moving fluid through the wound dressing and means for fluid cleansing, and optionally or as necessary the fluid supply tube;
e) means for supplying physiologically active agents from cells or tissue to the wound; and
optionally or as necessary means for bleeding the flowpath, such that fluid may be supplied to fill the flowpath and supply physiologically active agents from cells or tissue to the wound and recirculated by the device through the flow path.

Abstract
An apparatus for cleansing wounds in which irrigant fluid containing one or more physiologically active components from a means for supplying physiologically active agents from cells or tissue to the wound, e.g. an irrigant reservoir connected to a container that contains a cell or tissue component, in turn connected to a supply tube, connected to a conformable wound dressing and wound exudate from the dressing are moved by a device (which may be a single pump or two or more pumps) for moving fluid through a flow path which passes through the dressing and a means for providing simultaneous aspiration and irrigation of the wound. The latter removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing from cells or tissue and the physiologically active components in therapeutically active amounts in a precise and time-controlled manner over the wound bed.
