摘要

Mixing device for the manufacture of ready-to-use medical washing solutions, in particular for concentrates for hemodialysis, with a high purity water source (1), which is connected through an inlet conduit with a circuit of recirculation, in which a pump (7) is connected, with a computer (60) and with a secondary mixing connection conduit (18), which can be connected to a raw product container (20), which It contains, before the start of the mixing process, powdered and / or granulated and / or levigated raw products, which must be mixed with high purity water, being connected in the recirculation circuit, in the direction of circulation, one after the other a Venturi mixing tube (14) with a convergence chamber (65) and a divergence chamber (66) and a mixing valve (21), and the secondary mixing connection conduit (18) being connected to the suction point of the tub or Venturi (14), characterized in that another secondary mixing connection conduit (19) can be connected with the raw product container (20) and after a secondary mixing valve (23) flows into the recirculation circuit.
