The motor drives the driving wheel to pull the remaining follower wheels along the annular guide rail through the annular belt. The bracket fixed on the annular belt and the mixing device are fixed together, and the rotating mixing device moves along the annular belt to achieve the inverted mixing of the reagent in the test tube. The anticoagulant of the blood collection tube is attached to the four sides of the blood collection tube, and the collected blood generally does not fill the blood collection tube, so the inverted mixing method is conducive to the blood fully contacting the anticoagulant on the upper part of the blood collection tube, and the anticoagulant effect is obvious.

After completing venous blood collection with a blood collection tube, the blood collection tube should be placed on the blood collection tube bracket 25. The lower part of the blood collection tube bracket 25 has a clamping mechanism, which can fix the blood collection tube on the blood collection tube bracket 25. When the blood collection tube bracket 25 clamps the test tube and turns it upside down or rotates to mix, the test tube can be stably clamped. The motion principle of the rotating mixing device is that when the private service motor drives the active crank to drive the follower crank to rotate, the reagent in the test tube is rotated and mixed. The anticoagulant in the blood collection tube is attached to the surrounding of the blood collection tube. Under the premise of inverting and mixing, the blood collection tube is continuously driven to rotate and mix, which is conducive to full contact of the blood with the anticoagulant on the upper part of the blood collection tube, and the anticoagulant effect is obvious.
