Abstract

The invention relates to a moisture-containing soft-embedded cross-section specimen and a preparation method thereof, belonging to the technical field of bio-resin embedded cross-sections. The method for making the moisture-containing soft-embedded cross-section specimen comprises the following steps: freezing the biological specimen and sawing the sliced ​​cross-section specimen, soaking the cross-section specimen in a water treatment agent for water treatment, and obtaining The pretreated cross-section specimen; the pretreated cross-section specimen is placed in the mold, and the soft embedding agent is poured into the mold at a non-initiating temperature. The soft embedding agent has flexibility after curing; Cured, that is. By immersing the cross-section specimen in water, the water in the cross-section specimen can be completely locked, and the water will not come out to affect the embedding. Moreover, the water is locked in the cross-section specimen, which can retain the original state of the biological tissue and reproduce the state of the biological tissue more realistically.

Description

Technical field [0001] The present invention belongs to the technical field of biological resin embedding, and more particularly to a moisture-containing soft bag buried surface specimen and its production method thereof. Background technique [0002] Buried specimen technology is applied to the history of biological anatomical specimens, using resin technology to produce bioplastic specimens with non-toxic, tasteless, long-term storage, easy to use, long-term preservation in air. Advantage. [0003] When the existing biological specimens are embedded, the hard resin embed, that is, the hardness is high after the resin is solidified, and there is no elasticity. There are also soft embedded technology. Soft embedded specimens, not easy to crack, save time and clearer, which can be bent to multiple plus and directions. According to the invention, the present invention discloses a soft-enveloped surface specimen and a method of fabricating a method, which includes the following step...
