PURPOSE:To preparate much liquid medicine in a short period by providing a controlling valve of mixing quantity of medicinal liquid between the liquid tank and an injector and also providing a concn. monitor for detecting the mixed quantity of the liquid medicine between the injector and the liquid receiving tank. CONSTITUTION:The inside of tank 1 for medicinal liquid A is pressurized with a compressed air supplying means 6 to feed the medicinal liquid in the tank 1 to an injector 17. By the negative pressure induced when the pressurized medicinal liquid is passed through the injector 17, the medicinal liquid B in a tank 2 is sucked into the injector 17 and both the medicinal liquids are mixed thereby. When the concn. of mixed liquid medicine is checked with a concn. monitor 22 and the prescribed concn. is not satisfied, a changeover valve 21 of drain system is opened and a changeover valve 19 of a fluid receiving tank 3 side is closed and the mixed liquid is discharged via the drain system. When the mixed medicinal liquid is reached the prescribed concn., the changeover valve 21 is closed and the changeover valve 19 is opened and the mixed medical fluid is led into the tank 3 as a result. |
