BLOOD TREATMENT AND DISPOSABLE KIT FOR A BLOOD TREATMENT DEVICE

摘要

A blood treatment device, in particular a dialysis machine, which permits both single-needle and dual--needle operation, has a blood treatment unit, in particular a dialyzer 1, whose inlet is connected to a feed line 5 and whose outlet is connected to a return line 6. The feed line 5 has two parallel line branches 10, 11, with a first positive displacement pump 12 being connected into the first line branch and a second positive displacement pump 13 being connected into the second line branch 11. To produce a fluid connection between the outlet of the dialyzer 1 and one of the two pumps 13, a connection line 18 is provided. For dual--needle operation, the feed and return lines are connected to an arterial and a venous needle 32, 33, while for single-needle operation, the feed and return lines are brought together and connected to a common needle 9. The connection line 18 permits single-needle operation without great changes to the structure of the blood treatment device.
