Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a bone marrow smear staining device. Background Technology

[0002] Bone marrow smears are used to determine the degree of nucleated cell proliferation. Iron staining and various histochemical staining techniques used in bone marrow smears can provide diagnostic evidence for iron deficiency anemia and various types of leukemia. In routine examinations, bone marrow smears containing leukemia specimens require additional special chemical staining. However, the number of bone marrow smears is limited, so in daily practice, a single smear is often cut into 2-3 sections for special chemical staining. In clinical practice, when multiple smears are placed in the staining apparatus simultaneously, the overlapping of the smears causes uneven staining.

[0003] For example, CN202220674240.X discloses "A bone marrow smear staining device", in which bone marrow smears are inserted into slide slots on a glass support at one end, avoiding overlapping of blood smears or bone marrow smears, thus resulting in more uniform staining.

[0004] The above method of placing bone marrow smears into slide slots facilitates overlapping of smears and makes staining more uniform. However, when there are many blood smears that need to be stained, the above method cannot fully meet the needs of staining multiple sets of smears, resulting in a decrease in the staining efficiency of malaria blood smears and causing inconvenience to users.
