Preparation method for gastroscopy simulation model

Abstract

The invention discloses a preparation method of a gastroscopy simulation model, comprising the following steps of: firstly, preparing prepared ingredients into a waxy stomach tree with an inside stomach diameter, wherein the waxy stomach tree comprises parts from the cardia to the duodenum; secondly, spraying latex and dewatering; and at last, stewing and vulcanizing the waxy stomach tree by steam, demolding to obtain the finish product, and inspecting and assembling the finished product, wherein the ingredients comprise the following components in parts by weight: 5.5 parts of polyvinyl chloride paste resin P440, 1.5 parts of accelerating agent DM, 95 parts of butadiene-styrene rubber, 1.75 parts of accelerating agent M, 1.2 parts of anti-aging agent MB2, 1.5 parts of anti-aging agent D, 2.5 parts of accelerating agent CZ, 1.55 parts of anti-aging agent 4010, 8 parts of dibutyl phthalate, 8 parts of silicic acid, 2 parts of coumarone resin and 5.5 parts of natural rubber. The model prepared by the method disclosed by the invention is high in simulation degree; after adding the silicon oil to the stomach, the mirror feeling can be achieved; the model is similar to the living body, has favorable physical performance and can be repeatedly used; and the model is suitable for the stimulated training of the gastroscopy for teachers and students in the medical institutes and beneficial to teaching and practicing.

Description

technical field [0001] The invention belongs to the field of manufacturing medical teaching models, in particular to a method for preparing a simulation model for gastroscopy examination. Background technique [0002] In medical teaching, there is no teaching model for traditional gastroscopy. Students can only watch the actual operation in the hospital, but they do not get the opportunity to do it themselves. They cannot complete the training of practical skills in teaching, and they cannot see the stomach. Peristalsis process, poor teaching effect. Contents of the invention [0003] The purpose of the present invention is to propose a method for preparing a simulation model for gastroscopy, so that the prepared model has a high degree of simulation, and after adding silicone oil in the stomach, it can achieve a mirror-like feeling and be close to a living body. [0004] The present invention is achieved through the following technical solutions: [0005] A preparation ...
