Preparation method of frog cardiovascular and saccus lymphaticus lumen colored specimen

Abstract

The invention relates to a preparation method of a frog cardiovascular and saccus lymphaticus lumen colored specimen, aiming to solve the technical problem and provide a preparation method of a frog saccus lymphaticus vessel color-filling composite liquid by using materials such as a waste table tennis, anhydrous alcohol, xylene and a proper amount of oil paint and the like and a preparation method of an anticorrosive invariable composite liquid by using materials such as alcohol, glycerol, sodium chloride and water and the like. An uninjured live frog with a large body is selected and narcotized and then washed together with a frog cardiovascular lumen below a ventral sac, the internal parts of frog cardiovascular and saccus lymphaticus lumens are subjected to color-filling treatment, the materials are hardened in form and peeled off and trimmed, the anticorrosive invariable composite liquid is prepared and dehydrated, classified by an alcohol liquid and dried, subjected to color complementation, placed in a bracket and stored by a transparent shield to prepare a specimen having the same form as a real live frog cardiovascular and saccus lymphaticus lumen organ. The frog cardiovascular and saccus lymphaticus lumen colored specimen can meet the demands of veterinarian teachers and students in zootomy, animal physiology, animal pharmacology, food processing, agriculture and animal husbandry colleges in teaching and practice, scientific research institutions and the like, can be stored on dry kitchen shelves for a long period of time at normal temperature, is colored and has no peculiar smell.

Description

technical field [0001] The invention relates to a technique for preparing animal internal organ specimens, in particular to a method for preparing colored specimens of frog cardiovascular and lymphatic sac cavities Background technique [0002] At present, most of the teaching aids for animal visceral organs in domestic colleges and universities are limited to organ specimens soaked in chemical reagents, especially formalin soaked and encapsulated specimens are the most common, but in practical applications, formalin soaked specimens The disadvantages outweigh the advantages. For example, specimens soaked in formalin have the advantages of simple production, low material cost, and good antiseptic effect, but specimens soaked in formalin have the smell of formaldehyde, causing cancer, polluting the teaching environment, eroding the skin of the arms and affecting people's health, Recognized disadvantages are inconvenient use, pale, colorless and stiff specimens, and poor teac...

AI Technical Summary

Problems solved by technology

The frog cardiovascular and lymphatic sacs are filled with color to become dry finished colored specimens, completely overcoming the defects of formalin soaked specimens, such as smelly smell, eroding arm skin and affecting people's health, inconvenient use and storage, and poor teaching effect.
