Embodiment 1

[0035] The embodiment of the present application provides a foot bone in situ embedding method, the method comprising:

[0036] Step 110: polycondensing the dibasic acid and dibasic alcohol in the formulated amount to generate an unsaturated resin;

[0037]Further, the method includes: the heat distortion temperature of the unsaturated resin is 50-60°C; the thermal expansion coefficient of the unsaturated resin is 130×10 -6 ~150×10 -6 ℃.

[0038] Specifically, in the in situ embedding method of the foot bone provided by the embodiment of the present application, its raw material is mainly made of highly transparent crystal resin, that is, unsaturated resin, which is poured into a mold at one time to completely embed the human foot. During the experimental teaching process, students can more clearly observe the anatomical structural characteristics of the foot bones, the adjacent relationship of the foot bones, and the structural characteristics of the position of the foot bo...

Embodiment 2

[0055] The embodiment of the present application provides a foot bone in situ embedding model, which includes:

[0056] The raw materials are in parts by weight, the unsaturated resin is 100 parts by weight, the colorless cobalt accelerator is 1-3 parts by weight, the defoamer is 1-3 parts by weight, and the stabilizer is 1-2 parts by weight.

[0057] Further, the model further includes: a curing agent, the weight ratio of the curing agent to the resin mixture is 1:1.

[0058] Further, the relative density of the unsaturated resin ranges from 1.11 to 1.20; the defoamer is a silicone defoamer; the model is a transparent crystal; the storage temperature of the model is -10 to 50°C .

[0059] Specifically, the raw material of the foot bone in situ embedding model consists of 100 parts of unsaturated resin, 1 to 3 parts of colorless cobalt accelerator, 1 to 3 parts of defoaming agent and 1 to 2 parts of stabilizer agent composition, that is, adding 1 to 3 parts of colorless coba...

Abstract

The invention discloses an in-situ embedding method and model for foot bones. The method comprises the steps: performing the reaction of a formula amount of dibasic acid with dihydric alcohol to formunsaturated resin; adding a colorless cobalt promoter and an antifoaming agent to the unsaturated resin, and performing the uniform stirring and mixing to obtain a first resin mixture; adding a stabilizer to the first resin mixture, performing uniform stirring and mixing to obtain a second resin mixture; weighing the weight of the second resin mixture according to the casting weight of the foot bone, adding a curing agent at a certain proportion to the second resin mixture at the weight, and performing the uniform stirring to obtain a third resin mixture; measuring the size of the foot bone, and setting transparent glue at the joint of the foot bone; placing the foot bone at a predetermined position in a mold matched with the size, wherein the transparent glue at the joint of the foot boneis fixedly connected with the bottom surface of the mold; pouring the third resin mixture into the foot bone mold. The method achieves the technical effects of effectively avoiding a condition that the experiment teaching specimens are severely damaged, and improving the teaching quality.

Description

technical field [0001] The application relates to the technical field of medical teaching models, in particular to a foot bone in situ embedding method and model. Background technique [0002] Human anatomy is a very intuitive course, it is difficult to explain it without cadaver specimens and models, and it is also very difficult for students to understand. The use of models in the teaching process can stimulate students' interest in learning, improve the classroom teaching effect of human anatomy, and improve the teaching quality. The combination of model and corpse resources and multimedia courseware used in anatomy teaching can make classroom teaching intuitive and effective, help students quickly accept new knowledge in a short time, and can better solve the problem of image, image, Intuitive question. [0003] However, in the process of implementing the technical solutions in the embodiments of the present application, the applicant of the present application found t...
