A kind of bone marrow smear staining system

Abstract

The invention discloses a bone marrow smear dyeing system, which includes a bone marrow smear platform, a bone marrow staining platform and a dye solution recovery box. The bone marrow smear platform includes a movable baffle, a support plate and a slideway. A slideway is provided on the side, and a movable baffle is provided on the slideway, and the movable baffle is slidably connected with the slideway, and it can run along the slideway; the bone marrow staining platform includes a bottom wall, a rear sidewall, and a sidewall And the liquid discharge port, the top of which is open, the inner surface of the bottom wall is provided with two protruding ribs upwards, the top surface of the ribs is slightly inclined downward from front to back, and the rear part of the ribs is provided with an extension extending upwards The bottom wall is slightly inclined downward from the back to the front, and the front edge of the bottom wall is provided with a drain port, and the dye liquor recovery box is connected below the drain port. According to the invention, the fingers will not be polluted when the bone marrow slice is smeared, the bone marrow slice is convenient to take, and the operating table will not be polluted when the bone marrow is stained, saving time and effort.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a bone marrow smear staining system. Background technique [0002] As we all know, at present, when bone marrow smears are performed clinically, 0.1-0.2ml of bone marrow is first taken out with a straw, dropped on a glass slide, a drop of bone marrow is dipped with a pusher, placed on a glass slide (bone marrow slice), and pressed with a pusher. Push the bone marrow evenly on the bone marrow slice at a certain angle and speed; then wait for the bone marrow slice to dry naturally, and then move the bone marrow slice to the staining rack. into the surface of the bone marrow slices, blow the staining solution on the bone marrow slices evenly with a blowpipe, and after standing for a period of time, pick up the bone marrow slices with tweezers, take the bone marrow slices into the sink, and rinse them with running water from the tap; the bone marrow after washing After the...

AI Technical Summary

Problems solved by technology

[0003] In this method of the prior art, problems are prone to occur in the process of bone marrow smear and staining: 1) When pushing the bone marrow, generally one hand holds the pushing piece stained with bone marrow and places it on the side of the bone marrow piece. Hold the two ends of the bone marrow slice with one hand and the other hand, and then quickly push the push slice. When pushing the push slice, the fingers holding the end of the bone marrow slice are often easily stained with the bone marrow pushed by the push slice, causing contamination of the operator’s fingers , extremely unhygienic, if it is the bone marrow of patients suffering from infectious diseases, the operator will face the risk of infectious occupational exposure; 2) Bone marrow slices are generally thin glass slices, which are very inconvenient to take on a flat surface, time-consuming and laborious ;3) When staining bone marrow, because the staining solution is spread evenly on the bone marrow slice, it is easy to flow out from the bone marrow slice and flow onto the operating table, thus contaminating the operating table
