Description

technical field [0001] The invention relates to the technical field of pathological section dyeing machines, in particular to a multifunctional fully automatic liquid adding and discharging device for pathological section dyeing machines. Background technique [0002] Most of the fully automatic pathological slide staining machines currently in use are stained in the way of multi-tank dipping. 1. The reagent loading process of the traditional pathological section staining machine is manually operated to increase the number of staining tanks of the same reagent to improve the staining efficiency, so the number of staining tanks is far more than the types of reagents used. In the process of use, the replacement of reagents is also carried out manually, and the replacement process is cumbersome; xylene is included in the commonly used reagents, and manual replacement has a biological safety hazard. 2. The reagents used in the existing automatic pathological section staining ma...

AI Technical Summary

Problems solved by technology

1. The reagent loading process of the traditional pathological section staining machine is manually operated to increase the number of dyeing tanks of the same reagent to improve the staining efficiency, so the number of dyeing tanks is far more than the types of reagents used

In the process of use, the replacement of reagents is also carried out manually, and the replacement process is cumbersome; xylene is commonly used in reagents, and manual replacement has a biological safety hazard

2. The reagents used in the existing fully automatic pathological section staining machine are always stored in the staining tank, and all the staining tanks are always exposed to the air. It is difficult to ensure the stability of the reagents only when the tank is shut down.

3. When the traditional pathological slide staining machine manually loads reagents, it is usually difficult to accurately grasp the amount of reagents added. During the staining process, the reagents may overflow the staining tank when the slide carrier is immersed, causing pollution

4. For traditional dyeing machines that use pipelines to add liquid, there are generally defects such as slow liquid addition and incomplete drainage. At the same time, after multiple uses, the remaining stains on the dyeing tank and pipelines are difficult to clean, which will affect the next use

5. For the fully automatic dyeing machine that uses the pipeline to add liquid, when the pipeline valve fails or is blocked, if it cannot be found in time, the rapid increase of pipeline pressure will directly damage the pipeline

6. The effect of automatic dyeing has a certain relationship with the concentration of the reagent, but the traditional automatic dyeing machine is carried out in each dyeing tank, it is difficult to detect the concentration of all reagents in real time, the traditional automatic dyeing machine It is all calculated by calculating the number of staining times to estimate whether the staining concentration reaches the threshold and the reagent needs to be replaced, and no matter what the reagent concentration is, the staining process will not change, which will lead to uncontrollable staining effect
