A patient interface system includes a fluid transfer subsystem comprising a primary fluid transfer element fluidically communicating with the wound and a secondary fluid transfer element/manifold in contact therewith. A drape subsystem covers the fluid transfer elements and includes a film material membrane. A fluid conveying subsystem includes a vacuum source connected to the secondary fluid transfer element/manifold by a suction tube for creating a negative, sub-atmospheric pressure within the interface system for extracting fluids collected in the interface system. A fluid supply is provided for supplying various types of fluids to the interface system.

Medical patient fluid management interface system and method

A fastening system includes a membrane assembly which can comprise a pair of body panels secured together at a seam. The membrane panels can comprise a semi-permeable material. A sheath assembly has a tubular configuration with proximate and distal ends and a sheath passage extending therebetween. The sheath assembly can be fastened to the membrane assembly by adhesively securing the sheath assembly adjacent to its proximate end between the membrane panels at the membrane assembly seam. A sheath-to-tube fastener is provided for fastening the sheath assembly to a tube. In one embodiment of the present invention a surgical sponge is fastened to the membranes in fluidic connection with the sheath, which is fastened to a suction tube for drawing blood from a surgical site. A method of treating surface wounds such as burns, pressure ulcers and skin graft donor sites comprises the steps of applying a dressing including a foam section to the wound, adhesively applying a polymer sheet to the foam section, connecting a suction tube to with the foam section, applying negative pressure to the wound through the section tube by use of a motorized pump and directing fluid from the surface wound through the foam section by the polymer sheet.
