Description

Technical Field

[0001] The invention relates to the technical field of compound preparation mixing, in particular to a medicine mixer for preparing clinical compound preparations. Background Art

[0002] Clinical compound preparations refer to drugs composed of two or more known active ingredients, which usually have different mechanisms of action. They complement and synergize with each other to improve efficacy, reduce adverse reactions, and possibly improve patient compliance. Compound preparation mixers are equipment used in the pharmaceutical industry to mix drug raw materials. They are essential to ensure the uniformity and quality of drug preparations.

[0003] Existing compound preparation mixers use a stirring and mixing method to mix medicines. However, when the compound medicine is mixed and stirred, the flow rate of the part close to the stirring blade is fast and can be fully mixed, while the flow rate of the part of the medicine away from the stirring blade is slow and cannot be quickly and fully mixed. This leads to low mixing efficiency of the medicine, and the space retained in the mixing device will accumulate air, and some medicines will be contaminated by contact with the air and easily lose their effectiveness.

Then, the upper cover tube 1 and the lower card cover 21 are assembled with each other, so that the protrusion 26 on the motor 27 is clamped in the U-shaped block 25, and the turntable 29 is fixed between the upper cover tube 1 and the lower card cover 21. The turntable 29 is driven to rotate by the rotating shaft 28. The guide groove 210 on one side of the turntable 29 will squeeze the medicine liquid into the feed port 211, and then the medicine liquid is input into the mixing chamber 212 through the feed port 211. When the medicine liquid is input into the mixing chamber 212, it will collide with the medicine liquid accumulated inside.

[0020] Specifically, the fixing assembly 3 includes two upper clamping blocks 31, two lower clamping blocks 32 and two columns 34.

The motor 27 is started to drive the rotating shaft 28 to rotate, and the rotating shaft 28 drives the turntable 29 to rotate. The guide groove 210 on one side of the turntable 29 will squeeze the medicine liquid into the feed port 211, and then the medicine liquid is input into the mixing chamber 212 through the feed port 211. When the medicine liquid is input into the mixing chamber 212, it will collide with the accumulated medicine liquid inside, which will complete the mixing of the medicine liquid. The mixed medicine liquid is discharged through the feed port 211 at the other end, and the medicine liquid is reciprocated into the mixing chamber 212 through the turntable 29 for mixing. In this way, the medicine liquid inside the upper cover tube 1 and the lower card cover 21 can be driven to mix at the same time, so that the mixing efficiency of the medicine liquid is greatly improved.
