Dyeing method for medical experiment

Abstract

The invention discloses a medical experiment dyeing method which comprises the following steps: 1, starting a first suction mechanism to inject first dye liquor into a sample area, standing for a set time, and flushing the sample area to finish dyeing of the first dye liquor; 2, a second dye liquor suction pump is started to inject second dye liquor into the sample area, the sample area is washed after standing is conducted for set time, and dyeing of the second dye liquor is completed; 3, a third dye liquor suction pump is started to inject third dye liquor into the sample area, the color below the sample area is monitored in real time through the camera, the sample area is flushed when the color threshold point number is reached, and dyeing of the third dye liquor is completed; and 4, starting the second suction mechanism to inject fourth dye liquor into the sample area, standing for a set time, flushing the sample area, and completing fourth dye liquor sample injection for microscopic examination. According to the invention, manual operation is replaced by multi-station automatic dyeing liquid filling, so that the dyeing stability, consistency and color recognition accuracy are greatly improved, and dyeing result errors are avoided.

Description

technical field [0001] The invention relates to dyeing of medical experiment samples, in particular to a dyeing method for medical experiments. Background technique [0002] The dyeing of medical experiment samples is currently mainly done manually, including the following four steps: Step 1, after drying the sample on the sample area of ​​the sample container, add the first dye solution dropwise, and wash it with water after standing for a predetermined time; Step 2, apply the sample on the sample area of ​​the sample container Add the second dye solution dropwise to the area, and wash it with water after standing for a predetermined time; step 3, tilt the sample container, and slowly drip the third dye solution from above the sample area, so that the third dye solution flows through the sample area until the sample The third dye solution flowing down from the area becomes colorless, and then washed with water; step 4, the fourth dye solution is added dropwise to the sample...

AI Technical Summary

Problems solved by technology

[0004] 1. Manually take the sample container, add the staining solution dropwise with the staining solution bottle, and rinse the handheld sample container in the cleaning solution tank. The operation is cumbersome, and the stability and consistency are poor; and there is a risk of biological hazards in direct contact with medical experiment samples and chemical reagents

[0005] 2. The dyeing solution is atomized through the nozzle to complete the dyeing of the sample, but the dye solution is easy to crystallize, causing the nozzle to be blocked and difficult to maintain; and step 3 requires a fixed time, and the filling amount of the third dye solution cannot be adjusted according to the actual state of the sample, resulting in Excessive or insufficient staining in step 3 may easily lead to the risk of misdiagnosis;

[0006] 3. The dyeing solution is added in a dropwise manner. Since the time of the third dyeing solution is fixed, the filling amount of the third dyeing solution cannot be adjusted according to the actual state of the sample, resulting in excessive or insufficient staining, which not only leads to the risk of misdiagnosis of patients, but also wastes the first dyeing solution. Three dyeing solutions
