[0002] The workflow in modern medical testing laboratories primarily involves labeling, blood collection, transportation, mixing, and testing. Before blood samples are analyzed, they must be sorted based on label information so they can be sent to the appropriate testing center for centralized processing. Currently, specimen sorting is mostly done manually, which is labor-intensive and inefficient. Some hospitals use automated blood collection tube sorting equipment to perform this sorting.

[0003] The blood collection tube sorting equipment in the existing technology has functions such as specimen information reading and sorting, and directional specimen transportation. After the doctor at the blood collection window puts the collected specimen into the hopper, the specimen is automatically sorted and transported to the collection module without manual intervention, reducing the workload of medical staff and shortening the time to provide test reports, thereby improving work efficiency and service quality.
