Abstract
In a device for providing a substituate to a device for removing toxic substances from the blood which employs volumetric balancing of the fluid, an equalization chamber (11, 20) communicates with first and second inlet lines (9, 18) respectively, of a balancing chamber (14). Moreover, a buffer chamber (23) communicates with the first and/or second outlet line (15, 22) of the balancing chamber (14). The volume prevailing in the buffer chamber (23) that communicates with the first or second outlet line (15 or 22) can be so varied that the volume expands when the second or first equalization chamber (20 or 11) is emptied, and is reduced when the second or first equalization chamber is filled. As a result, the discontinuous pulse is smoothed on the outlet side of the balancing chamber.
