Dry type manufacturing method of animal specimen

Abstract

The invention relates to a dry type making method for animal specimen that includes six steps: collecting material, reshaping antisepsis fix and tube cavity cast, alcohol dewatering fix, glycerol process, turpentine impregnation and air drying, material repairing tinction preservation or seal up for keeping. Thereinto, in step 1, the animal material is bleed and killed via health quarantine, in step 2, potting it with the formalin with colorless glycerin and phenol or alcohol solution, in step 3, controlling the concentration of every step and fixed time, in step 4, marinating it with glycerol moisture absorption soften liquid, and transfer it from low concentration to high concentration of glycerin, and the time is prolonged gradually, in step 5, treating it with turpentine continually, in step 6, printing it. The invention improves the present technique, the quality of specimen is improved greatly, and that can keep the original state of material, the color and the luster. The dried specimen is sanitation without peculiar smell, and good at handle and quality.

Description

(1) Technical field: [0001] The invention relates to a method for making animal specimens for anatomy teaching, in particular to a dry method for making animal specimens. (2) Background technology: [0002] Anatomical teaching specimens are often used in the teaching of biology and medicine. [0003] The anatomy teaching specimens are produced in the following ways according to the different materials of the animals themselves: [0004] 1. Traditional formalin immersion method. The various materials were immersed in formalin solution for preservation. Suitable for a variety of materials, including muscles, organs, fur, bone. 2. Bone specimen preparation method: Bleaching and sun-drying by boiling method, pit burial method, chemical degreasing method. Suitable for bones. 3. Peeling specimen method. Suitable for fur. 4, alcohol, glycerol soaking method. Soak various materials in alcohol solution and glycerin solution for preservation. Suitable for various materials. ...

AI Technical Summary

Problems solved by technology

[0006] The disadvantages of the formalin soaking method are: 1. Since formaldehyde will continue to volatilize, it is necessary to add formalin solution at regular intervals.

2. The smell of formaldehyde pollutes the air, and the formalin liquid has an erosive effect on human skin, which is unhygienic

3. It is inconvenient to use, and it is necessary to turn over the cylinder and take it out in advance

4. Poor tissue elasticity, pale and stiff muscles

[0020] 3. The material is directly soaked in 4-8% formaldehyde or 78% alcohol solution for fixation, the material is not fully anti-corrosion, and it is easy to mold and deteriorate;

[0021] 4. After the material is dried, it has not been painted and air-dried. The surface of the dried specimen lacks a protective layer against moisture and embedding foreign matter, and it is easy to mold and deteriorate.
