Closed tissue dehydrator

Abstract

The invention relates to a closed tissue dehydrator. The closed tissue dehydrator is provided with a box body, wherein a reagent cylinder group, a reaction cylinder and a paraffin cylinder group are arranged in the box body; the reagent cylinder group comprises an alcohol cylinder group and a dimethylbenzene cylinder group; at least two openings are formed in the bottom of the reaction cylinder; switching valves are correspondingly arranged on the openings; at least two openings comprise a paraffin inlet and outlet which is communicated with the paraffin cylinder group and a liquid inlet and outlet which is communicated with the reagent cylinder group; at least one liquid inlet and outlet is formed; the paraffin cylinder group is communicated with the paraffin inlet and outlet through a paraffin distribution valve; the reagent cylinder group is communicated with the liquid inlet and outlet through a reagent distribution valve; the number of the reagent distribution valve is matched with the number of the liquid inlet and outlet; and a heating and heat-insulating device is arranged on the periphery of the reaction cylinder, the paraffin cylinder group and the paraffin distribution valve. By the closed tissue dehydrator provided by the invention, the problem of liquid mixing is solved by supplying the paraffin and other solvents separately; and the situation that equipment cannot work normally and fails because paraffin enters a reagent pipe to form paraffin blockage is avoided.

Description

technical field [0001] The invention relates to a closed tissue dehydrator. Background technique [0002] For pathological diagnosis of diseases, the tissue samples submitted for inspection need to be fixed, dehydrated, transparent, and soaked in wax to make paraffin block slices. The tissue dehydrator automatically immerses human or animal and plant tissues in various solvents for dehydration and transparency. , wax dipping and other pathological analysis pretreatments, suitable for use in laboratories of medical colleges, hospital pathology departments, medical research units, animal and plant research units, and food testing departments. [0003] Existing tissue dehydrators are divided into two categories according to their working methods. One is to arrange several reagent tanks with different solutions such as alcohol, xylene, liquid paraffin and other processing solutions in a circular or linear arrangement, and then use a mechanical arm to remove the tissue. The spec...

Problems solved by technology

The tissue dehydrator of this type of structure passes different solutions such as alcohol, xylene, and liquid paraffin through the same liquid distribution valve, because paraffin is solid at room temperature, it needs to be heated until it melts when used, and other solvents do not need to be heated when used at room temperature , leading to the fact that the paraffin is easy to escape into the reagent tube at room temperature and solidify to form a wax plug during use.
