Description

Technical Field

[0001] This utility model relates to the field of blood collection tube holder technology, and in particular to blood collection tube holders used in clinical laboratories. Background Technology

[0002] Blood collection is a process that the laboratory needs to assist with testing or related procedures. Blood collection tubes are generally cylindrical in shape and cannot be placed upright. Placing blood collection tubes horizontally can easily cause blood to separate into layers. Therefore, blood collection tube stands are needed to keep the blood collection tubes upright.

[0003] Blood collection tube racks are generally made of transparent plastic material with multiple sets of holes on the surface for holding blood collection tubes. However, existing blood collection tube racks do not have a partitioning function. There are many types of blood collection tubes, and if they are all placed on one blood collection tube rack, it is not possible to quickly find the same type of blood collection tube during inspection. In addition, in order to ensure the stability of the blood collection tubes, the depth of the blood collection tube rack is generally only slightly higher than the blood collection tubes, which makes it inconvenient to pick up the blood collection tubes.

[0004] Therefore, to address the aforementioned issues of inconvenience in handling and lack of partitioning functionality, a blood collection tube holder with partitioning functionality and ease of handling can be designed. Utility Model Content
