Manufacturing method for adult cattle jugular vein intravenous injection model

Abstract

The invention relates to a manufacturing method for an adult cattle jugular vein intravenous injection model, and the method comprises the steps: preparing a release agent, plaster and silicone rubber; selecting an adult cattle body, and peeling a neck; separating and washing a jugular vein, a carotid artery and a sympathetic nerve trunk, inserting supporting tubes into the jugular vein and the carotid artery, coating the external surfaces of the jugular vein and carotid artery with the supporting tubes and the surface of the sympathetic nerve trunk with the release agent and the silicone rubber, and preparing a silicone rubber model; coating the neck of a cattle head with the release agent and plaster, and preparing a cattle head neck mold; enabling the silicone rubber model to be embedded into a jugular vein groove of the cattle head neck mold, pasting cowhair uniformly outside, enabling the cattle head to be raised, and preparing the cattle jugular vein intravenous injection model. The prepared cattle jugular vein intravenous injection model is excellent in performance, is complete and beautiful in structure, is clear and natural in shape and position, can be used for the repeated practice, and irons out the defect that the intravenous injection of the jugular vein of a live cattle cannot be carried out repeatedly.

Description

technical field [0001] The invention relates to a method for making an animal model, in particular to a method for making an adult bovine jugular vein injection model. Background technique [0002] Jugular vein injection is often used for injection and infusion of large animals such as cattle, horses, and donkeys. However, most beginners cannot complete the operation smoothly during learning. Cause animal neck hematoma, moreover, can't many people repeatedly operate at the same time. The production of adult bovine jugular vein injection models is not only used as an intuitive and vivid teaching aid in the teaching of "animal anatomy and histology", but also allows students to participate in the production process, so that students can understand the model production process and master this technology, and at the same time train students Hands-on, brain and operational ability. However, how to make an adult bovine jugular vein injection model with beautiful appearance, high...

However, how to make an adult bovine jugular vein injection model with beautiful appearance, high quality and safe materials is a key problem for researchers

[0003] At present, the production of animal tissue models is mostly the same. The bovine jugular vein injection model produced by using traditional reagent formula and production process cannot meet the requirements of safety, image, environmental protection, high quality and other aspects. For example, plaster milk prepared by traditional formula , high hardness, poor plasticity, unsatisfactory water retention effect, prone to cracking when placed for a long time, affecting the appearance quality of the model; when preparing silicone rubber, the precise ratio of crosslinking agent and curing agent is not uniform, and the curing time and tensile strength cannot be achieved. At the same time, etc.; when making traditional models, formaldehyde or similar solutions are often used to achieve antiseptic purposes. These reagents are extremely volatile and have a strong pungent smell, which can cause damage to human organs. Long-term exposure may also cause cancer and serious harm. human health
