Abstract

The invention relates to a blood vessel casting medium, a flexible blood vessel cast specimen and a preparation method of the flexible blood vessel cast specimen, and belongs to the technical field ofbiological embedding. The blood vessel casting medium is prepared from the following components in parts by mass: 100 parts of a casting material, 15 to 30 parts of a solvent, 0.3 to 0.8 part of a plasticizer and 3 to 7 parts of a softening agent, where in the casting material is one or more of chlorinated polyvinyl chloride, perchloroethylene or polyvinyl chloride; the softening agent is one ormore of liquid nitrile rubber and liquid polysulfide rubber. The flexible blood vessel cast specimen prepared using the blood vessel casting medium is relatively high in flexibility and not easy to deform in long-term storage.

Description

technical field [0001] The invention belongs to the technical field of biological embedding, and in particular relates to a blood vessel casting agent, a ductile blood vessel casting specimen and a preparation method thereof. Background technique [0002] At present, commonly used vascular cast specimens for teaching and learning in schools include: impregnated specimens and model specimens. The structure of the model specimen is simple, and there is a certain deviation between the teaching and the real specimen, and the display of the name of the specimen from the shallow layer to the deep structure cannot be realized. The preparation process of dipping bottled specimens is simple, they need to be stored in liquid, they cannot be exposed to the air for a long time, it is difficult to observe and study, and they are poisonous and have a pungent smell, and the blood vessels are easy to break during use, which affects the appearance of the specimen. [0003] Cast specimen tec...
