Method for preparing specimen of animal stomach and intestine organ

Abstract

The invention relates to a method for preparing a specimen of an animal stomach and intestine organ, for providing solutions to technical problems, i.e., methods for preparing a stomach and intestine wall blood vessel coloring combination liquid by using such materials as waste and damaged table tennis balls, waterless ethanol, acetone, butanone, a proper amount of oil painting pigments and the like, and stomach and intestine cavity filling and combination materials prepared by such materials as a colorless 808 silicone sealant, acetone, oil painting pigments and the like. The method comprises: selecting a fresh animal stomach and intestine organ which is lossless in structure; washing the organ cavity with water and performing coloring treatment on cavity outer wall blood vessels; filling the stomach and intestine with air and performing fixing and corrosion prevention; respectively filling the cavities of the stomach and intestine with different monochromatic combination materials; and performing color complementation and shaping, installing a support, painting and drying, and preserving with a transparent cover so as to prepare a colored dry specimen having the same stomach and intestine organ form as a real live animal. By using the provided method, the needs of animal husbandry and veterinary specialties for animal dissecting, clinic diagnosis and treatment, and animal internal and external obstetrics, the needs of agriculture and husbandry colleges for teaching and practice, and the needs of scientific research institutions and the like are well met, the specimen can be stored at a normal temperature for a long time with color and without unfavorable flavor, and the taking and storing of such a teaching aid are quite convenient.

Description

technical field [0001] The invention relates to a technique for preparing animal organ specimens, in particular to a preparation method for animal gastrointestinal organ specimens. Background technique [0002] At present, most of the teaching aids for animal gastrointestinal organ teaching specimens in domestic colleges and universities are limited to organ specimens soaked in chemical reagents, especially formalin soaked and packaged specimens are the most common, but in practical applications, formalin soaked Specimen has more disadvantages than advantages. For example, specimens soaked in formalin have the advantages of simple production, low material cost, and good anti-corrosion and fixing effect. However, specimens soaked in formalin have the smell of formaldehyde, causing cancer, polluting the teaching environment, and eroding the skin of the arms, which affects people's health. , inconvenient use, pale and colorless specimens stiff and poor teaching effect and othe...
