Biological tissue dehydration device based on chain transmission and dehydration method thereof

Abstract

The invention discloses a biological tissue dehydration device based on chain transmission and a dehydration method thereof. The biological tissue dehydration device comprises a machine frame and a reagent cylinder arranged in the machine frame, wherein horizontal supporting wheels are arranged under the machine frame, a horizontal chain is wound on the horizontal supporting wheels, the horizontalchain is connected with a horizontal driving wheel, a horizontal linear bearing is fixed with the horizontal chain, the horizontal linear bearing is arranged on a horizontal lower guiding rail in a penetrating mode, the horizontal lower guiding rail is fixed with the machine frame, the horizontal linear bearing is connected with a lifting module, an installation hanging basket is arranged on thelifting module, and the hanging basket is used for accommodating biological tissue samples. According to the biological tissue dehydration method based on the chain transmission disclosed by the invention, retention time of the hanging basket in the reagent cylinder is inversely proportional to an alcohol concentration, a product between the retention time of the hanging basket and the alcohol concentration is a fixed constant value, and the retention time of the hanging basket can be adjusted according to the alcohol concentration in the reagent cylinder. By means of the biological tissue dehydration device based on the chain transmission and the dehydration method thereof disclosed by the invention, a biological tissue dehydration technology efficiency is improved, a biological tissue dehydration efficiency is high, and transmission accuracy is high.

Description

technical field [0001] The invention relates to the technical field of precision medical instruments, in particular to a chain-driven biological tissue dehydration device and a dehydration method thereof. Background technique [0002] Pathological tissue specimens need to be fixed, dehydrated, transparent, and soaked in wax before they can be made. At present, the biological tissue dehydration device includes a transmission part and a tissue dehydration process part. The boom and the hanging basket move up and down, left and right, and the hanging basket is connected with the lower part of the boom. The pathological tissue is put into the hanging basket, and the hanging basket automatically runs up, down, left, and right according to the program of the equipment, and the tissue specimens are put into the reagent tanks of the dehydrator in order to soak in a close to manual manner. After the pathological tissue in the hanging basket has finished soaking in a reagent vat, the...

AI Technical Summary

Problems solved by technology

In the biological tissue dehydration device of the prior art, the up, down, left, and right movements of the hanging basket are all driven by belts or steel wires. The transmission accuracy is low, the stability is poor, and the positioning accuracy is usually at the millimeter level, and fatigue damage is prone to occur after long-term use, which affects the transmission. Efficiency, and the hanging basket stays in each reagent vat for the same time, the hanging basket cannot adjust the residence time according to the change of alcohol concentration in the reagent vat, and the efficiency of the biological tissue dehydration process is low
