Description

Pathological staining jar capable of monitoring water-containing state Technical Field The utility model relates to the technical field of pathological staining jars, in particular to a pathological staining jar capable of monitoring a water-containing state. Background HE staining techniques, which are an indispensable feature in histopathology, greatly facilitate microscopic observation of tissues by virtue of their ability to separate different tissues into different colors. In the HE full-automatic staining process, a certain amount of water is often entrained by a staining rack and a glass slide after washing, and then the water enters a subsequent gradient ethanol staining cylinder. Meanwhile, when the external humidity rises, the open alcohol dyeing cylinder is easy to absorb water vapor in the air. It is particularly critical that if water is mixed in the cylinder in the final two absolute ethanol staining steps, this water will be carried into the subsequent xylene staining cylinder. Since xylene and water are not compatible with each other at normal temperature, excessive water causes delamination. Once the xylene reagent jar is permeated with moisture, the transparency treatment of the slices is greatly compromised, so that the moisture on the slices is difficult to thoroughly remove, and the sealing operation of the centering gum is interfered. The slice can show brown bubbles with different sizes under a microscope, even presents an opaque or turbid state, seriously hinders the comprehensive examination of the tissue morphology by a diagnostician, and greatly slows down the speed and efficiency of the reading of the slice. In the face of such problems, the slices often need to be re-fabricated or undergo cumbersome re-dewatering, transparency and sealing procedures, which undoubtedly add a heavy workload to the pathologist. The root cause of the series of problems is that the xylene and the absolute ethyl alcohol are transparent and colorless liquid, and a technician only has difficulty in judging whether the reagent contains water or not and the proper time for replacing the reagent. There is a need for a device that can monitor the presence of moisture in a pathology stain jar. Disclosure of utility model The utility model provides a pathological staining jar capable of monitoring a water-containing state, which can solve the problem that whether water in xylene solution in the existing pathological staining jar is difficult to distinguish by naked eyes. The pathological dyeing cylinder capable of monitoring the water-containing state comprises a cylinder body, wherein a transparent grid sheet is transversely arranged at the position, close to a bottom plate, of the lower part of the cylinder body, a water-containing monitoring space is formed between the transparent grid sheet and the bottom plate, a plurality of color-changing substances are placed in the water-containing monitoring space, the color of the color-changing substances changes after absorbing water, a hollowed-out hole is formed in the bottom plate of the cylinder body, a detachable lower cover is arranged at the hollowed-out hole, the position of the color-changing substances can be limited by the transparent grid sheet, the color-changing substances cannot be poured out due to pouring of reagents in the pathological dyeing cylinder, and can be precipitated in the water-containing monitoring space due to the fact that the density of water is higher than that of the xylene reagents, and the color-changing substances can be seen from an opening at the upper end of the cylinder body after absorbing water, so that whether the reagents in the xylene dyeing cylinder need to be replaced or not can be intuitively judged. Preferably, the color-changing substance takes a porous silicon dioxide entity as a carrier, and the surface of the color-changing substance is impregnated with anhydrous cobalt chloride, so that the color-changing substance has strong moisture absorption capacity and sharp perception of humidity change. Preferably, the bottom plate comprises a horizontal part positioned in the middle and inclined surface parts arranged on two sides of the horizontal part, and the inclined surface parts extend to the side wall of the cylinder body, so that the color-changing substances can be gathered on the upper side of the horizontal part, and the color-changing substances are convenient to observe in a concentrated manner. Preferably, the upper side of the horizontal part is provided with a plurality of limit grooves side by side, the color-changing substance is placed on the limit grooves, and the limit grooves increase the drifting resistance of the color-changing substance. Preferably, the color-changing substance is spherical, and the bottom section of the limiting groove is arc-shaped, so that the color-changing substance is conveniently and rapidly discharged along with the dimethylbenzene reagent. Preferably, a cylinder cov
