A top cover assembly and biological sample processing equipment

Abstract

The invention provides a top cover plate assembly and biological sample processing equipment. The top cover plate assembly includes: a top cover plate for loading a tray on which a glass slide and a liquid cover film are placed; The reagent needle pierces through the reagent needle; the pressing unit is installed on the top cover plate, and is used to press down the moving liquid cover membrane, so that the liquid cover membrane and the slide glass are in close contact; wherein, the pressing unit includes : the fixed main body is fixed on the top cover plate, and the fixed main body is provided with an avoidance structure corresponding to the reagent needle perforation for avoiding the reagent needle; Carry out elastic top pressure. By setting the pressing unit to make the liquid cover film and the slide glass in close contact, the evaporation of the reagent is reduced, the moisturizing effect of the biological sample is guaranteed to the greatest extent, and the processing effect of the biological sample is guaranteed. In addition, the avoidance structure can avoid the reagent needle, so that the addition of the reagent will not be affected while pressing the liquid cap membrane.

Description

technical field [0001] The invention relates to the technical field of biological sample processing, in particular to a top cover assembly and biological sample processing equipment. Background technique [0002] When processing biological samples, it is necessary to place the biological sample on a glass slide, use the liquid cover film and the glass slide to cooperate to form a very thin reaction chamber, and add the reaction liquid to one end of the reaction chamber to fully react the biological sample with the reaction liquid , these operations can currently be achieved by biological sample processing equipment. [0003] For example, a sample smear processing device (that is, a biological sample processing device) disclosed in the Chinese invention patent application with the application publication number of CN104089808A, the device includes two cam brackets, and a heating module mounting seat is installed on the upper part of the cam bracket. A plurality of heating mo...

AI Technical Summary

Problems solved by technology

[0006] When the above-mentioned biological sample processing equipment is in use, due to the action of the heating module, the biological sample on the glass slide is incubated with the reagent at high temperature. Although there is a liquid cover film on the glass slide, the reagent will still evaporate at high temperature, especially in the liquid cover. If the membrane cover is not tight, the evaporation of reagents will be serious, and the moisturizing effect of biological samples cannot be guaranteed, which will affect the treatment effect
