Portable Ultrafiltration Unit And Device For Supplying The Ultrafiltration Unit With Dialysis Fluid

摘要

The invention relates to a portable ultrafiltration unit A which comprises a blood pump 7 for conveying blood and an ultrafiltration pump 6 for conveying ultrafiltrate. The invention further relates to a stationary device B for supplying dialysate to the portable ultrafiltration unit A, and to a medical treatment system which comprises an ultrafiltration unit and a device for supplying dialysate to the ultrafiltration unit. The ultrafiltration unit according to the invention is in the form of a unit to be connected to a stationary device for supplying dialysate to the ultrafiltration unit, in such a way that a fluid connection can be established for feeding in fresh dialysate and removing used dialysate. As a result, the ultrafiltration unit can not only be used for ultrafiltration, but also, when used in conjunction with the stationary device for supplying dialysate to the ultrafiltration unit, for a blood treatment as carried out by a conventional blood treatment device. It is merely necessary to connect the ultrafiltration unit A to the device B for supplying dialysate to the ultrafiltration unit. There is no need to detach the patient connections 27A, 27B of the venous and arterial blood lines 27, 28 or to attach said connections to the patient, as result of which the preparation time for a blood treatment can be reduced.
