摘要

Mixing device for the manufacture of ready-to-use medical washing solutions, in particular for hemodialysis, with an ultrapure water source (1), which is connected by a power line with a recirculation circuit (36), in which is connected to a pump (7), and with a computer (61), and with a connection duct (18), which can be coupled with a raw material container (19), which contains from the beginning of the process mixing powdered and / or granulated and / or grout raw materials, which must be mixed with ultrapure water, being connected in the recirculation circuit, one after the other, a main valve (14), a Venturi mixing tube / aeration (16) with a convergence chamber (78) and a divergence chamber (79) and an auxiliary filling valve (45), characterized in that in parallel, a secondary mixing valve (13) and a secondary Venturi tube ( 15) with a convergence chamber (78 ) and a divergence chamber (79) are connected in the connection conduit (18) derived from the recirculation circuit (36), and by which the suction points of the Venturi tubes (15, 16) are connected by a conduit ( 17).
