Device for the removal of substances from liquids in particular blood

摘要

The invention relates to an apparatus for the elimination of substances from liquids, in particular from blood, comprising a primary circuit for the liquid to be treated, a filter which is integrated therein and at whose secondary side a secondary circuit is connected in which at least one adsorber is arranged, wherein respective pumps are provided in the primary and secondary circuits. In accordance with the invention, an expansion vessel in which liquid of the secondary circuit is discontinuously taken up and output again is integrated in the secondary circuit.

1. An apparatus for eliminating substances from a liquid, in particular from blood, said apparatus comprising:
a primary circuit in which the liquid is treated; a filter integrated in the primary circuit, said filter having a secondary side that is a part of a closed secondary circuit in which at least one liquid treatment element that is an adsorber is arranged, the adsorber being a sorbent cartridge or equivalent, with respective pumps being provided in the primary and secondary circuits, the filter separating the primary circuit and the closed secondary circuit from each other, and the secondary side of the filter being directly connected to the closed secondary circuit; an expansion vessel integrated in the secondary circuit, said expansion vessel being configured to take up a liquid of the secondary circuit from the filter in a first phase and then output the liquid of the secondary circuit back to the filter after the secondary circuit liquid has flowed through the adsorber in a second phase; a first line and a second line of the secondary circuit, the first line and the second line each being connected to the filter, with the expansion vessel being arranged between the first line and the second line of the secondary circuit, and with the adsorber being integrated in the second line; a secondary circuit pump connected to the first line and the second line in parallel with the expansion vessel; and an outlet line of the expansion vessel, the first line, and a first side of the secondary circuit pump being connected in a first connection point, and an inlet line of the expansion vessel, the second line, and a second side of the secondary circuit pump being connected in a second connection point.
