Therapy delivery systems and methods

摘要

Fluid removal systems and methods for removing a fluid from a tissue site are presented. The systems includes a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to the tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site of a patient. The treatment-fluid collector receives a treatment fluid and the fluid, which is recruited, from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of the recruited fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls the recruited fluid from an interstitial and intracellular space. A reduced-pressure treatment subsystem may also be included, among other things, for removing ascites and other fluids from a body cavity.

主权项

1. A method for removing a fluid from a tissue site, the method comprising:
placing a semi-permeable inbound conduit proximate to the tissue site; fluidly coupling a treatment-fluid delivery unit to the inbound conduit, the treatment-fluid delivery unit operable to deliver a treatment fluid to the inbound conduit; placing a semi-permeable outbound conduit proximate to the tissue site; fluidly coupling a conduit interface comprising a plurality of tributary conduits sized for a patient's abdominal cavity between the outbound conduit and the inbound conduit; and disposing the treatment fluid within the treatment-fluid delivery unit.
