Abstract

An extracorporeal blood chamber (12) comprises an expansion reservoir (47) having a first access (48) arranged laterally and a second access (49) arranged on the bottom of the chamber (12). The chamber comprises, integrally with the reservoir, a first conduit terminating in the first access, a second conduit terminating in the first access, and a third conduit terminating in the second access. The extracorporeal blood enters the reservoir through the first conduit and there mixes with an infusion fluid which enters through the second conduit. The resulting mixture exits through the third conduit. The chamber is used in a hemo(dia)filtration apparatus to mix the blood optimally with the replacement fluid.
