[0026] The weighing mechanism 7 is fixedly installed between the support frame 2 and the weighing tank 3 , and is used for weighing the medicine in the weighing tank 3 .

[0027] First, a support frame 101 is fixedly installed at the bottom of the mixing tank 1, and a first infusion pump 102 is fixedly installed at the bottom end of the mixing tank 1. The input end of the first infusion pump 102 is connected to the mixing tank 1 through a connecting tube 103, and an infusion tube 104 is fixedly connected to the output end of the first infusion pump 102. The support frame 101 provides support for the mixing tank 1.

[0028] Furthermore, a motor 105 is fixedly installed at the center of the bottom of the mixing tank 1, a stirring shaft 106 is rotatably connected inside the mixing tank 1, and the bottom end of the stirring shaft 106 is fixedly connected to the output end of the motor 105, a plurality of groups of stirring blades 107 are fixedly connected to the outside of the stirring shaft 106, and a stirring frame 108 is fixedly connected to the top of the stirring shaft 106. After all the medicines are introduced into the interior of the mixing tank 1, the motor 105 is started to drive the stirring shaft 106 to rotate, and the medicines are stirred by the plurality of groups of stirring blades 107 cooperating with the stirring frame 108, so that the medicines are fully mixed.

[0029] Then, a second drain pipe 301 is fixedly connected to the bottom of the weighing tank 3, and a first solenoid valve 302 is fixedly installed at the connection between the second drain pipe 301 and the weighing tank 3, and the bottom end of the first drain pipe 6 is slidably connected to the top of the weighing tank 3. Before introducing various medicines into the interior of the mixing tank 1, the different medicines are first introduced into the interior of the weighing tank 3, and the second drain pipe 301 is closed by the first solenoid valve 302. After the different weighings are completed, the second drain pipe 301 is opened by the first solenoid valve 302 to introduce the medicines into the interior of the mixing tank 1 for mixing. At the same time, when the weighing tank 3 is weighed, the weighing tank 3 is suspended on the inner side of the support frame 2, and the first drain pipe 6 is slidably connected to the weighing tank 3.

The output end of the second infusion pump 501 is connected to the inside of the medicine inlet barrel 5. When different medicines are added and mixed, the suction tubes 503 on the inner side of the corresponding medicine tank 4 are first opened through the second solenoid valve 504, while the suction tubes 503 on other medicine tanks 4 are closed. The second infusion pump 501 is started to extract the medicine in the medicine tank 4, and then introduced into the inside of the medicine inlet barrel 5, and then introduced into the weighing tank 3 through the first discharge tube 6 for weighing.

The tops of the S-type weighing sensors 702 are fixedly connected to the support frame 2 through connecting rods 703. After the medicine is introduced into the interior of the weighing tank 3, the S-type weighing sensors 702 on the connecting ears 701 will be pulled downward under the action of gravity. The introduction is stopped after the required amount of medicine is reached, and then the weighed medicine is introduced into the mixing tank 1. Various medicines are weighed and added and mixed in turn, so as to be added in a fixed proportion for stirring and mixing, thereby meeting the use requirements of the chemiluminescence immunoassay and avoiding waste of medicines.

[0033] In this embodiment, the implementation scenario is specifically as follows: when adding and mixing different medicines, first open the extraction tube 503 on the inner side of the corresponding medicine tank 4 through the second solenoid valve 504, and close the extraction tubes 503 on other medicine tanks 4, start the second infusion pump 501 to extract the medicine in the medicine tank 4, and then introduce it into the interior of the medicine cartridge 5, and then introduce it into the weighing tank 3 through the first discharge tube 6 for weighing. After the medicine is introduced into the weighing tank 3, the S-shaped weighing sensor 702 on the connecting ear 701 will be pulled downward under the action of gravity. The introduction will be stopped after the required amount of medicine is reached, and then the weighed medicine will be introduced into the mixing tank 1, and various medicines will be weighed and added and mixed in turn to add all the medicines. After the medicine is introduced into the mixing tank 1, the motor 105 is started to drive the stirring shaft 106 to rotate, and the medicine is stirred by multiple groups of stirring blades 107 and the stirring frame 108, so that the medicine is fully mixed. After the medicine in the mixing tank 1 is mixed, the first infusion pump 102 is started to extract the medicine through the connecting tube 103, and the infusion tube 104 is connected to the chemiluminescence immunoassay. The medicine is transported to the inside of the chemiluminescence immunoassay through the infusion tube 104. The whole operation process is simple and convenient. Compared with the existing chemiluminescence immunoassay liquid preparation mechanism, the utility model can be added in a fixed proportion for stirring and mixing through design, which meets the use requirements of the chemiluminescence immunoassay and avoids waste of medicine.
