Teaching model for human body hepatic portal vein system anatomy and demonstrating method based on model

Abstract

The invention discloses a teaching model for human body hepatic portal vein system anatomy and a demonstrating method of the human body hepatic portal vein system based on the model. The structure comprises a model box, an organ model and a vein system model are arranged in the model box, the organ model is composed of models of part of human organs, the vein system model is composed of vein models with the constitution being the same as that of the human body hepatic portal vein system, the vein models are hollow tubes made of a transparent material, LED lamp strips are arranged in the vein models in a penetrating manner, the LED lamp strips are connected to a power supply controller, and switch buttons used for controlling power supplies of the LED lamp strips are arranged on the power supply controller. According to the technical scheme, through the combination of sound, light and shape, the human body hepatic portal vein anatomy and blood circulation during the hepatic portal veinhypertension can be completely, accurately and intuitively displayed, so that a student can more easily understand the complicated anatomy structure, through practical teaching verification, the learning progress and understanding of the student for the relevant knowledge of the human body hepatic portal vein can be accelerated and deepened, in addition, the model device is integrally arranged inthe box, and thus teaching transfer is facilitated.

Description

Technical field [0001] The invention relates to a medical teaching equipment, in particular to a teaching model of the anatomy of the human hepatic portal vein system. Background technique [0002] Anatomy of the hepatic portal vein system and blood circulation during hepatic portal hypertension are important learning content of human anatomy. The hepatic portal vein is the confluence of the superior mesenteric vein and the splenic vein up to the hepatic portal. It divides into the left and right lobes of the liver. After repeated branches in the liver, it enters the hepatic sinusoids and mixes with blood from the branches of the proper hepatic artery. Metabolized blood is injected into the inferior vena cava through the hepatic vein. The hepatic portal vein has seven branches, including the superior mesenteric vein, splenic vein, inferior mesenteric vein, left gastric vein, right gastric vein, gallbladder vein and umbilical vein. [0003] Under normal physiological conditions, t...

AI Technical Summary

Problems solved by technology

The anatomical structure involved in the blood circulation of the hepatic portal vein system is complex, but the current teaching method is mainly through the atlas teaching method, which is too abstract, the three-dimensional effect is relatively poor, and there is no comparison between normal and hepatic portal hypertension blood flow changes, so it is difficult to intuitively , Comprehensively display the normal blood flow path and pathological changes of the hepatic portal vein system, resulting in poor learning effect for students on the hepatic portal vein system
