Gerät zur Behandlung von Flüssigkeiten in einem Kreislauf.

摘要

The present invention relates to an apparatus for treating fluids in a circuit comprising a source of fluid (1) to be treated and a receiver for the treated fluid (2), a fluid circuit comprising at least a first compliant fluid line (3) leading from said source to the inlet of a membrane device (4), a pump (5) interconnected in said first fluid line being operative to deliver a substantially continuous fluid flow to said membrane device, a second compliant fluid line (6) leading from the outlet of said membrane device to said receiver and at least one device being operative to create a positive flow in said fluid circuit. To increase performance of the apparatus the device for creating a pulsatile flow is a single-roller pump (7) operative to cause a temporary positive pressure gradient between the outlet and the inlet of the membrane device.
