Sample staining device

Abstract

The invention discloses a sample staining device which comprises a staining platform, a glass slide support structure and a glass slide driving mechanism, wherein the staining platform is provided with a staining solution and cleaning solution supply part; the glass slide support structure is located on the two sides of the staining platform and forms a certain clearance between a glass slide and the staining platform; and the glass slide driving mechanism allows the glass slide and the staining platform to move by keeping a certain clearance. When the device works, a staining solution is supplied to the staining platform; a convex liquid level is formed due to surface tension; when the glass slide moves to the convex liquid level of the staining solution, the staining solution performs infiltration and is diffused in the clearance between the staining platform and the glass slide to cover the glass slide to stain a sample; the staining time is determined by a movement stroke and speed of the glass slide in a staining solution area; and after the glass slide is stained, the cleaning solution is supplied to clean the residual staining solution to accomplish a staining process. The device is simple in structure; a glass slide conveying mechanism can allow multiple glass slides to pass through the staining platform for staining sequentially in a flowline manner; and the device has high working efficiency when the device is used for massive sample staining.

Description

technical field [0001] The invention relates to the technical field of medical testing, and more specifically, to a sample dyeing device. Background technique [0002] In the field of medical testing, staining is a test method in which the tissue and intracellular structure of the specimen to be tested are stained differently by means of one or more dyes, so that the internal structure of the cell can be clearly observed under the microscope, which can be used as a clinical test. diagnosis to make a correct judgment. [0003] Existing specimen staining is divided into manual staining and automatic staining. Automatic staining is completed by an automatic staining device. The existing automatic staining device mainly includes two mainstream structures, one of which uses multiple staining boxes to stain each smear. The efficiency is low, and it is difficult to adapt to the needs of large-scale work. Another dyeing execution device uses a dyeing disc to dye multiple smears at ...
