Method for making stuffed animal specimen of hairless vertebrate and injector adopted by same

Abstract

The invention belongs to the technical field of animal specimen making and particularly relates to a method for making a stuffed animal specimen of hairless vertebrate and an injector adopted by the same. The invention discloses a special method for making a stuffed animal specimen of hairless vertebrate according to the basic characteristics of hairless vertebrate and based on the special advantages of alpha-cyanoacrylate compounds and by use of a specially designed alpha-cyanoacrylate compound injector. The front end of a needle is totally sealed; the inner wall of an inner cavity of the needle is completely and tightly inlaid with a teflon material, injection holes are uniformly distributed on the outer wall of the front end of the needle, and the alpha-cyanoacrylate compound is prevented from being adhered to the inner cavity wall of the needle and generating a polymerization reaction and blocking the injection channel; and moreover, residue is avoided, the number of needle holes of the injector in the animal specimen surface is greatly reduced, the problem of non-uniform filling is effectively solved, and the method for making a stuffed animal specimen of hairless vertebrate from alpha-cyanoacrylate compound is perfected.

Description

technical field [0001] The invention belongs to the technical field of animal specimen production, and in particular relates to a method for producing hairless vertebrate animal specimens and a syringe used therefor. Background technique [0002] Animal specimens are the first-hand information of biological science research and the best material for practical teaching. For students, animal specimens are the best tools to cultivate observation skills, discover problems and acquire new knowledge. And with the continuous development of the times and the continuous progress of the economy, the use of animal specimens is not limited to scientific research and teaching, but as a decoration, a decoration for companies, and even a way for pet breeders to commemorate the accidental death of pets. way into people's lives. However, most of the existing animal specimen preparation methods use toxic substances such as formalin, phenol, and arsenic for preservation, and these agents wil...

AI Technical Summary

Problems solved by technology

However, most of the existing animal specimen preparation methods use toxic substances such as formalin, phenol, and arsenic for preservation, and these agents will cause a certain degree of harm to the specimen maker and specimen user, and the preparation method is complicated and the operation process is difficult. High technical requirements and high production costs limit the scope of use and practical value of specimens

[0003] α-cyanoacrylate compounds have many advantages in the production of animal specimens, such as wide sources, low cost, simple operation, and non-toxicity. Alpha cyanoacrylate compounds are difficult to make animal specimens, especially in the process of making reptiles, amphibians and cartilaginous fishes, because the body surface of these animals is not protected by hair and hard scales, and most animal morphological structures It is relatively complicated, so in the production process, not only the difficulty and cost of making such animal specimens are often increased due to the complexity of prosthesis production, but also the reaction speed of α-cyanoacrylate compounds is too fast and the uneven response is greatly reduced. It reduces the success rate of making such animal specimens, reduces the quality of making such animal specimens and the aesthetics of finished products

For example, in the process of making shark specimens in cartilaginous fishes, the muscle tissue of sharks is very dense, which is not conducive to the penetration and sealing of α-cyanoacrylate compounds, and even the α-cyanoacrylate compounds used for sealing Only attached to the body surface of shark specimens

Although the method of filling with absorbent cotton can effectively guide the α-cyanoacrylate compound to penetrate into the shark's muscle tissue, but sharks are cartilaginous fishes, there is no evolved abdominal cavity and ribs, only one spine from top to bottom, and The use of α-cyanoacrylate compounds to make this specimen requires the shark to be completely dehydrated before it can be sealed and preserved. In addition, the filling of absorbent cotton will cause serious deformation and distortion of the shark specimen after it is made, completely losing the shark's natural vitality. Some streamlined fish lose their ornamental value and market value

The disadvantages and deficiencies specific to the use of α-cyanoacrylate compounds to make animal specimens not only exist in the process of making animal specimens of cartilaginous fish such as sharks, but also exist in the incomplete skeletal system and more morphological structure. In the process of making animal specimens of complex amphibians and reptiles with special morphological structures such as snakes and turtles

[0004] Although there are various types of syringes of α-cyanoacrylate compounds on the market now, due to different application fields, the syringes of α-cyanoacrylate compounds that exist in the market can only be used for smearing on the surface of objects, and cannot Not suitable for internal injections and taxidermy of various animals, especially taxidermy of hairless vertebrates

It can be said that many problems such as uneven filling of α-cyanoacrylate compounds, excessive reaction speed and distortion of finished specimens caused by uneven reaction have restricted the use and development of α-cyanoacrylate compounds in specimen production. Its improvement and innovation are imperative
