Abstract
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.
