Problems solved by technology

[0003] The injection and infusion of medium-sized animals such as pigs, rabbits, and sheep often use the method of ear vein injection. However, most beginners cannot complete the operation smoothly during learning, which often causes animal ear hematoma. Moreover, it cannot be performed repeatedly by multiple people at the same time.
[0004] Ear vein injection is the key and difficult part of animal administration in the practical teaching of animal medicine. The practical links in the teaching of systematic anatomy are mainly theories more than practical operations. Moreover, students in the teaching of regional anatomy generally only read the chapters in the books. Line drawings, but do not know the shape, color, size, etc. of specific organs and tissues

Abstract

Provided is a method for manufacturing a pig ear intravenous injection model based on mathematical modeling. The method comprises the steps that firstly, agentia is prepared, and the caudal vein is separated; then the prepared agentia is utilized for manufacturing a pig ear mold and an ear vein silicone rubber model, the ear vein silicone rubber model is embedded into an ear vein groove of the pig ear mold, and wrapped by a skin model, and the pig ear intravenous injection model can be manufactured. The method is simple, cost is low, the manufactured ear intravenous injection model is easy to store, complete and attractive in structure, clear and natural in form position, and capable of being used for repeated practice, the defect that live pig ear intravenous injection cannot be repeatedly operated is overcome, the problems that a beginner usually injects a pig repeatedly, and repeated ear intravenous injection cannot be carried out on a live pig are solved, the teacher teaching time is shortened, the learning interest of students is stimulated, and the teaching effect is improved.

Description

technical field [0001] The invention relates to a method for making a test animal model, in particular to a method for making a pig ear vein injection model based on mathematical modeling. Background technique [0002] An animal model is a representative individual of the same species that keeps the animal body structure as it is or can be used as a reference for learning and research. It can also be used as an important reference for scientific research, teaching, and popularization of scientific and technological knowledge. Animal and tissue models contain irreplaceable scientific value, ornamental value and collection value, just like other works of art, they have entered shopping malls, exhibition halls and homes, becoming new indoor decorations for people. A well-made model not only brings people knowledge, but also brings people artistic enjoyment. A perfect animal model is not only a vivid practical teaching aid, but also a superb work of art. It represents a univers...
