Abstract

A method for making silica gel model of stomach section of sheep comprises steps of performing perfusion and fixation of animal carcass with special fixing agent to keep natural state in sheep body, filling with melted polyethylene glycol, cutting open stomach, exposing to gastric surface, brushing with special mold releasing agent, and brushing with silicone rubber and gypsum to prepare gypsum and silicone rubber female mold and male mold. The silicone rubber has good fluidity and is easy to fit the fine structure of the internal and external surface of the stomach, and the sturdiness of thegypsum is utilized to prepare the organ model with precise and exquisite structure and vivid reality, which solves the problem of poor realistic feeling of the previous model.

Description

technical field [0001] The invention relates to a method for making an adult animal digestive tract model, in particular to a method for making a sheep stomach section silica gel model. Background technique [0002] Animal models have morphological structures similar to animals and can convey animal morphological information. It can be used for science popularization, teaching, exhibition and other purposes. The digestive tract is the channel for animals to eat, obtain nutrients, and excrete metabolites. The study of the structure of the digestive tract plays an important role in improving the digestive and absorption functions of animals, improving feed utilization, reducing breeding costs, improving breeding efficiency and economic benefits. Sheep is an economic animal, and mutton is rich in nutrition and loved by the masses of the people. Sheep are ruminant herbivores, and the stomach of the digestive tract is divided into rumen, reticulum, omasum and abomasum, with com...
