Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood slide dyeing device. Background Art

[0002] In the fully automatic slide staining machine, the staining device is a key component that determines the staining quality of the blood smear. There are two commonly used staining methods for traditional staining devices: multi-slide staining method and single-slide staining method.

[0003] The multi-slide staining method is to place multiple prepared blood smears in a glass slide basket, and then immerse the basket containing multiple blood smears in a staining tank for staining. After staining according to the set process, the basket containing the blood smears is taken out and the next staining process is carried out. The dye in the staining tank can be recycled. However, after repeated use of the dye, the staining effect decreases, which will cause inconsistent staining effects of different batches of blood smears, affecting the diagnosis of relevant clinical pathology. In addition, in actual use, there are often emergency samples or small sample quantities, and large batches of samples cannot be stained at the same time, that is, a single or a few blood smears also require a large amount of dye, which causes a large amount of dye waste and greatly increases the cost of single-slide staining.

[0004] The single-slide staining method is to place the blood smear in a separate staining box for staining. Each staining pool only contains one blood smear. The volume of the staining box is small enough, and only a small amount of dye needs to be added each time to effectively stain the blood smear. When the blood smear sample size is small, the reagent consumption is lower than when staining multiple slides. When the blood smear sample size is large, the staining effect is better than the multiple slide staining method.

[0005] Some of the dyeing devices of the traditional single-sheet dyeing method have dyeing boxes that cannot be recycled, and some have complex structures, large volumes and low working efficiency. Utility Model Content
