Description

A convenient and hygienic automatic slide staining device

technical field

The utility model relates to the technical field of medical inspection, in particular to a convenient and hygienic automatic glass slide staining device.

Background technique

At present, when doing experiments such as microbiology and cell biology, staining agents are often used to observe various bacteria, cells, etc. When staining, it is necessary to drop staining reagents on the surface of slides containing samples, and the staining results are often very poor. It is not ideal, and in most cases, the dyeing solution is easy to splash out during the dyeing and cleaning process, thereby polluting the surrounding environment and making it difficult to clean.

In the prior art, there are generally two staining methods for glass slides: one is staining vat staining, that is, the staining vat is filled with staining solution, and the slides are directly put into the staining vat for staining; the other is staining. Button dyeing method, that is, on a clean glass plate, place two waste glass slides in parallel at a distance of 55mm as a bracket, buckle the slide with the sample side down on the bracket, and drop the dye solution on the glass slide The side of the slide, using capillary phenomenon to suck the dye solution between the slide and the glass plate. Compared with the vat dyeing method, dyeing with a vat requires about 50ml of dyeing solution, while dyeing with button dyeing requires about 2-4ml of dyeing solution. The use of button dyeing can not only save dyes, but also prevent the dyed particles from settling on the specimen, affecting the quality of the specimen. observe. However, since there is no finished button dyeing device at present, there are some problems in the use of the button dyeing method: 1. The operation is relatively complicated, and a clean and horizontal glass plate and a glass slide as a support must be prepared, and the glass slide must be adjusted each time it is used. 2. Air bubbles are easy to be generated during operation, so that some chromosomes are not stained; 3. Due to the gap problem of the temporarily assembled button-dyeing device, the gap between the glass slide and the glass plate used as the bracket and the stained slide are caused. The siphon phenomenon of the staining solution between the slides and the cleanliness of the glass plate caused the staining solution to flow out, wasting nearly double the staining solution.
