Abstract

A tube set intended for extracorporeal treatment of blood and similar perishable liquids, e.g. by dialysis, includes a spacer adapted to rigidly connect an inlet end of a pump segment for a tube pump to an outlet end of the pump segment. The spacer is adapted to transfer liquid to and from the pump segment. Ports may be provided in the spacer for the purpose of withdrawing liquid samples from the spacer or supplying reagents or priming fluids to the liquid flowing through the spacer. A stay formed integrally with the spacer supports the spacer against the tube pump.
