Sample reaction cabin and detection reagent adding method

Abstract

The invention discloses a sample reaction cabin and a detection reagent adding method. The sample reaction cabin comprises an upper cover and a lower cover which are fixed together in a detachable connection manner; a slide is arranged between the upper cover and the lower cover, and the upper part of the upper cover is provided with a cylinder; the cylinder comprises an upper opening in the top end and a lower opening in the lower surface of the upper cover, the lower cover is provided with a locating hole, the diameter of the locating hole is smaller than the inner diameter of the cylinder, and the projection area of the locating hole in the slide is in the projection area of the lower opening in the cylinder on the slide. In comparison with the prior art, the sample reaction cabin and the detection reagent adding method provided by the invention can accurately determine the positions of the tissue slices and cell smears by moving the slide in the detection process, subsequently can directly add the reagent needed for detection through locating by a machine, and thus, the adding process of the reagent is simplified, more obviously, dosage of the reagent can be reduced greatly, and the detection cost is saved.

Description

[0001] technical field [0002] The invention relates to a preparation device for cell detection samples, in particular to a sample reaction chamber and a method for adding detection reagents. [0003] Background technique [0004] Cell samples need to be observed and tested after staining. When staining cells, a staining chamber is needed. The existing staining chamber usually includes a cylinder and a glass slide placed under the lower opening of the cylinder. When adding the staining agent , first place the cell sample on the glass slide, then move the slide so that the cell sample is in the projection area of ​​the lower opening of the cylinder on the glass slide, and then add the dye from the upper opening of the cylinder so that the dye completely covers the lower opening of the cylinder In the projection area on the glass slide, it can ensure that the staining agent completely covers the cell sample, ensures that the staining agent fully reacts with the cell sample, ...

AI Technical Summary

Problems solved by technology

[0005] Since the existing staining chamber cannot determine the position of the cell sample, that is, it cannot accurately determine where the cell sample is located in the above-mentioned projection area, it is necessary to add more dyes so that the dye completely covers the above-mentioned projection area. , the staining agent is relatively expensive, which makes the cost of cell staining very high. If the amount of staining agent is reduced in order to control the cost, it is very likely that the amount required for the reaction will not be met.
