After work, can fold vein nutrient solution configuration frame, bracing piece and down tube can keep flat on the low step of base, and left and right stand and crossbeam are then kept flat on the high step of base and are pressed on bracing piece and down tube to in accomodate, can also save space.

Although the above patent facilitates the medical staff to prepare the liquid medicine through the arrangement of the configuration rack, in practical application, we find that there still exist certain disadvantages, such as:

the configuration rack can not quantitatively configure liquid medicines with different proportions, has low automation degree, needs manual configuration, and still has the problems of easy misconfiguration and misconfiguration;

based on this, we propose a quantitative dispensing device for intravenous configuration, which hopefully solves the shortcomings in the prior art.
