Description

Technical Field

[0001] The utility model belongs to the field of vacuum blood collection tube conveying equipment, in particular to a vacuum blood collection tube loading device. Background Art

[0002] The workflow of modern medical testing laboratories primarily involves labeling, blood collection, transportation, and testing. Before blood specimens are analyzed on the machine, they need to be sorted according to the label information so that they can be sent to the corresponding testing center for centralized processing. Currently, specimen sorting is mostly done manually, which is labor-intensive and inefficient. Some hospitals use automatic sorting equipment for vacuum blood collection tubes, which has functions such as specimen information reading and sorting, and directional specimen transportation. After the doctor at the blood collection window places 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 it takes to provide test reports, thereby improving work efficiency and service quality. For this type of equipment, the smooth transportation and single-row arrangement of the vacuum blood collection tubes are key to completing specimen sorting. Utility Model Content
