EINRICHTUNG ZUR HERSTELLUNG EINER MEDIZINISCHEN FLUESSIGKEIT

摘要

An apparatus for preparing a medicinal solution, in particular dialysis solution, from pulverulent concentrate and water comprises a water source (12) from which a first conduit (14) is led to a container which contains the powder and from which a second conduit (20) into which a first measuring cell (22) and a concentrate pump (24) are connected leads to a mixing point (28). Said mixing point (28) is located in a third conduit (26) which leads from the water source to a consumer; downstream of the mixing point (28) a second measuring cell (30) is provided for monitoring the composition of the finished dialysis solution. Since the two measuring cells (22) and (30) lie in different conduits in which solutions of different composition are conveyed, there is no possibility whatever of confusions between concentrates of the same initial conductivity but different final conductivity after dilution with water.
