Leitungs-System zum Spülen eines extrakorporalen Kreislaufs bei der Hämodialyse, Hämofiltration und Hämodiafiltration

摘要

An extra-corporeal haemodialysis, haemodiafiltration and haemofiltration system is flushed using a sterile electrolyte- and/or carbo-hydrate soln. and/or sterile water in a piping system comprising a hose connecting the arterial union to a pouch of flushing liq., and a further one between the venous union and a collector vessel. The hoses are connected by a third one contg. a valve shutting off the flow in the direction of the collector vessel. A valve in the arterial hose shuts off flow in the direction of the pouch, and the collector vessel is of variable volume. The third hose can be connected to the others by Y-unions, and volume can be varied by clamping off part of the vessel, or by folding it. ADVANTAGE - Greater economy in use of soln., and largely automatic in operation.
