Abstract

The invention discloses a detachable heart model for teaching show. The detachable heart model comprises a simulated lung, a simulated body, a left heart model and a right heart model, wherein the left heart model comprises a left ventricle model, an aorta model, a left atrium model and a pulmonary vein model; the right heart model comprises a right ventricle model, a suprahepatic vena cava model,a right atrium model and a pulmonary artery model; one side of the left heart model is hinged with one side of the right heart model by virtue of a connector; the connector comprises a left heart connecting shaft, a right heart connecting shaft and an intermediate connecting shaft; the intermediate connecting shaft is connected between the left heart connecting shaft and the right heart connecting shaft; and light strips are arranged in the heart model, the simulated lung and the simulated body according to blood circulation. According to the detachable heart model disclosed by the invention,sorting of the heart structures can be changed according to the blood circulation process in the teaching process, and the flow sequence of blood in the heart is intuitively shown. Meanwhile, the structure of each part of the heart can be independently displayed, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heart teaching, in particular to a detachable heart model for teaching display. Background technique [0002] Human blood circulation is divided into systemic circulation and pulmonary circulation. Systemic circulation: left ventricle → aorta → arteries at all levels → systemic capillaries → veins at all levels → capillary network → veins at all levels in the body → superior and inferior vena cava → right atrium. Pulmonary circulation: right ventricle→pulmonary artery→pulmonary capillary→pulmonary vein→left atrium. As the engine of human blood circulation, heart teaching is particularly important. [0003] In order to strengthen students' understanding in the heart teaching process, the heart model is usually used, but the existing heart model is usually just a solid model, and the process of blood circulation cannot be clearly displayed during the teaching process, and at the same time, the various parts...
