Tissue embedding box

Abstract

The invention belongs to the technical field of pathology equipment, solves the technical problems in the prior art that an incubator and a cold table are used manually to carry out preheating, cooling and re-preheating on an embedding box, as a result, the process is tedious, manpower is consumed, the progress is affected, and skin injury of an operator is caused by the too high temperature of the preheated embedding box, and solve the problems that when being taken out, an embedding block, with residual wax remaining around, cannot be directly used for slicing, and block trimming and re-precooling are needed before slicing. The adopted technical scheme is as follows: the embedding box comprises a pressure sensing device positioned at the bottom and an automatic temperature adjusting device connected with the pressure sensing device, a tissue embedding area positioned at the middle part and a dehydration box fixing area positioned at the top. According to the technical scheme, pressure sensing is adopted to control the temperature adjustment, and the incubator or the cold table is not needed, so that space is saved; a thermal insulation material is arranged outside the embedding box, so that skin injury of the operator caused by the high temperature is avoided; the embedding block taken out can be directly used for slicing, and block trimming and re-precooling are not needed before slicing, so that time and manpower are saved, the cost is reduced, and the working efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of pathological instruments, and in particular relates to an embedding cassette for tissues. Background technique [0002] In pathological technical work, paraffin embedding is required after tissue dehydration. Before embedding, place the embedding cassette in a hot environment for preheating. The temperature must reach the melting point of paraffin. Pour part of the liquid paraffin into the embedding box, put the tissue samples in, and then move the embedding box to the cold table. When the paraffin at the bottom of the embedding box starts to solidify, lightly press the tissue sample to fix the specimen at the bottom of the embedding box. Insert the dehydration box into the upper part of the embedding box, pour paraffin into the embedding box again, so that the paraffin liquid level is higher than the bottom of the dehydration box, move the embedding box to the cold table until the temperature drops, an...

Problems solved by technology

This process involves the temperature change of the embedding box. The preheating and cooling process takes too long, which cannot meet the needs of the operator’s daily embedding speed, affects the embedding progress, and requires the cooperation of other personnel to move the embedding box filled with paraffin. It is time-consuming and labor-intensive to lay out multiple cold tables for cooling. At the same time, the temperature of the preheated embedding box is too high, which may easily cause skin damage to the operator during embedding. In addition, there is residual wax around the embedding block removed after cooling, which cannot It is directly installed on the fixed device of the microtome for slicing. It is necessary to trim the block first, remove the residual wax around it, and then slice it after pre-cooling again, which wastes cost, cumbersome process, and reduces work efficiency.
