[0002] The fully automated biochemical analyzer is an instrument that measures a specific chemical component in body fluids based on the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy, and low reagent consumption, it is now widely used in hospitals, epidemic prevention stations, and family planning service stations at all levels. When used in conjunction with other instruments, it can greatly improve the efficiency and benefits of routine biochemical testing. Different samples need to be added during the operation of the fully automated biochemical analyzer.

[0003] Existing technologies have the following problems:

[0004] A search revealed that Chinese patent application number CN202222820491.7 discloses a sample dispensing mechanism for a fully automated biochemical analyzer used in medical testing. This patent uses a first suction branch tube to draw water to clean the suction tube, self-priming pump, infusion tube, support, flow meter, and sample dispensing needle. However, after cleaning, residual moisture remains inside the infusion tube, support, flow meter, and sample dispensing needle, which not only poses a risk of bacterial growth but also leads to deviations in the final test results.
