Abstract

The invention relates to a water-containing softly-embedded section specimen and a manufacturing method thereof, and belongs to the technical field of biological resin embedded sections. The manufacturing method of the water-containing softly-embedded section specimen comprises the following steps: freezing a biological specimen, sawing the biological specimen to for sheet section specimens, and soaking the section specimens in a water treatment agent for moisture treatment to obtain pretreated section specimens after the soaking is finished; putting the pretreated section specimens to a mold,and pouring a soft embedding agent into the mold at a non-initiation temperature, wherein the soft embedding agent has flexibility after being cured; and performing curing at an initiation temperature after the pouring is finished to obtain the product. The section specimens are soaked in the water to completely lock the water in the section specimens, so the water cannot flow out to influence embedding. The water is locked in the section specimens, so that the original state of biological tissues can be retained, and the state of the biological tissues can be truly reproduced.

Description

technical field [0001] The invention belongs to the technical field of bioresin embedding section, and in particular relates to a water-containing soft embedding section specimen and a preparation method thereof. Background technique [0002] Embedded specimen technology has been applied to the field of bioanatomical specimens for nearly 30 years. Bioplasticized specimens produced by resin technology have the advantages of non-toxic, odorless, long-term storage, convenient use, and long-term storage in the air. [0003] When the existing biological specimens are embedded, they are generally embedded in hard resin, that is, the resin has high hardness and no elasticity after curing. There are also soft embedding techniques. Soft-embedded specimens are not easy to crack, can be stored for a long time and the specimens are relatively clear, and can be bent to multiple additions and directions. The invention patent with application publication number CN109523873A discloses a s...
