After the extraction is completed, shake the syringe directly to mix the liquid and powder, and then inject into the patient's body through the suction needle. The whole process only requires one suction and one injection, and no prior preparation is required. Effectively simplify the operation steps.

Further, the through-flow hole is arranged at the bottom of the connection between the piston cylinder and the mixing cylinder to ensure that the piston cylinder has a sufficient suction volume, and the piston can slide in the piston cylinder in the Sufficient negative pressure is generated in the mixing drum.

Further, the pipe wall of the suction pipe is provided with a number of liquid-separating holes, and the liquid-separating holes are all arranged on a section of the liquid suction pipe in the mixing cylinder, and the liquid suction pipe is pumped at the liquid suction needle. When the water for injection is sucked, the water for injection can be dispersed and sprayed in the mixing cylinder through the liquid separation hole, so that the mixing of the water agent and the powder agent is more uniform.

Further, the top of the bottle inserting needle is provided with a powder hole, and the inner diameter of the powder hole is not less than 5mm, so that the powder in the powder bottle can enter the mixing cylinder through the powder hole, and the efficiency of mixing and dispensing is improved.

(3) Beneficial effects:

Compared with the prior art, the beneficial effect of the present utility model is: by arranging the piston cylinder and the mixing cylinder side by side, and setting the liquid suction needle connected with the liquid medicine bottle and the bottle insertion needle connected with the powder medicine bottle on the mixing cylinder, The water and powder can be mixed by one suction, which greatly simplifies the dispensing steps, improves the dispensing efficiency, and is simple and convenient to use.
