TWO-WAY TRANSMEMBRANE DRAINAGE Russian patent published in 2009 - IPC A61M27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to surgery, and can be used for debridement of purulent wounds and cavities, and for prevention and treatment of purulent-septic complications following operative interventions or wounds. A two-way transmembrane drainage accommodates a membrane capsule comprising a tubular perforated microirrigator encased in the cavity of a semipermeable membrane. The proximal part of the capsule approaches a dialysis fluid vessel through said microirrigator. The distal part of the capsule is connected to a dialysate discharge vessel through the microirrigator which represents two interrelated dropping systems without injection needles. A reversible two-clamped suction tube is used for complementary connection of the two vessels. Said tube along with the microirrigator passes through paired sleeves of the membrane capsule. Besides, the vessels are joined with paired metal needles with their ends advanced through rubber stoppers of both vessels and are supplied with paired air bleeds with air vents in the bottom.

EFFECT: ensuring high-quality energy-saving active dialysis, eliminating application of complicated, bulky active dialysis apparatuses, simplifying and reducing the cost of transmembrane dialysis technology.
