In actual operation, it is very difficult to achieve a standard balance in the distribution of drugs. At the same time, it takes a lot of energy for pharmacists to complete the distribution work, which not only delays work efficiency, but also may prevent the treatment from achieving the best effect. A drug distribution device proposed in the prior art publication number CN215753310U includes a shunt cylinder, a triangular baffle and a funnel. A partition passing through the axis of the shunt cylinder is vertically arranged in the shunt cylinder. The partition equally divides the inside of the shunt cylinder into six independent chambers at equal intervals. The bottom surfaces of the six independent chambers are all connected with material distribution pipes. The top end of the side wall of each independent chamber is provided with a notch for inserting the triangular baffle. A circular through hole is provided in the center of the top surface of the shunt cylinder. The bottom of the funnel is adaptively connected to the circular through hole. However, different patients require different amounts of liquid medicine to be drunk.
