Pathological tissue dehydrator with automated valve channel system

Abstract

The invention relates to a pathological tissue dehydrator with an automated valve channel system, which comprises a working cylinder, three wax cylinders and a plurality of solvent bottles, wherein the three wax cylinders are respectively a first wax cylinder, a second wax cylinder and a third wax cylinder, output pipes of the first, second and third wax cylinders are respectively correspondingly provided with a first valve, a second valve and a third valve, the first, second and third valves are converged and communicated to an inlet of a three-position two-way reversing valve by pipes, an outlet of the three-position two-way reversing valve is communicated to the working cylinder by a pipe, the other inlet of the three-position two-way reversing valve is communicated with a rotary distributing valve by a pipe, a plurality of interfaces on the rotary distributing valve are respectively correspondingly communicated with the plurality of solvent bottles one by one, a rotating shaft of the rotary distributing valve is provided with a positioning plate, and the positioning plate is rotatablely connected with a stepping motor. According to the invention, paraffin waxes and other medicaments are separately supplied, and an effect of carrying out collection and harmlessness treatment on chemical volatile gases in other solvent bottles is achieved.

Description

technical field [0001] The invention relates to the technical field of tissue dehydration machines, in particular to a pathological tissue dehydration machine with an automatic valve circuit system. Background technique [0002] Pathological dehydration is to immerse pathological tissue biopsy specimens in formalin, alcohol, xylene and melted paraffin in a certain order and for different lengths of time, fix the pathological tissue, dehydrate, transparent, and soak in wax, and then send it to the next step for packaging. Buried slices. [0003] Biopsy specimens: Small specimens such as gastroscopy, bronchoscopy, liver biopsy, kidney biopsy, endometrium, etc., and large specimens such as surgical resection of stomach, breast, thyroid, and uterus. [0004] Pathological tissue fixation, dehydration, transparency, and wax immersion are essential steps in routine pathological film production, and are also the key to ensure the quality of film production. The process of replacin...
