Coronary heart disease teaching model

Abstract

The invention discloses a coronary heart disease teaching model. The coronary heart disease teaching model comprises a base, a supporting tube and a heart model, wherein the supporting tube and the heart model are sequentially fixed at the top end of the base, and the heart model is connected with the base through the supporting tube; the heart model comprises a myocardium and a coronary artery, and the coronary artery is located on the surface of the myocardium; a plurality of three-color LED lamps are arranged in the myocardium, and a plurality of two-color LED lamps are arranged in the coronary artery; and a control board, a wireless transmission module and a power supply are arranged in the base, and the three-color LED lamps, the two-color LED lamps, the wireless transmission module and the power supply are electrically connected with the control board. The coronary heart disease teaching model disclosed by the invention is used for identifying a heart coronary artery anatomical structure and pathological changes and is combined with clinical typical ECG performance, so that it is easier for learners to understand and memorize, thereby improving the teaching efficiency and quality.

Description

technical field [0001] The invention relates to the technical field of teaching models, in particular to a teaching model of coronary heart disease. Background technique [0002] Myocardial infarction of coronary heart disease refers to the sharp reduction or interruption of coronary artery blood supply, resulting in severe and persistent ischemia of the myocardium leading to myocardial necrosis. It is a more serious type of coronary heart disease. trend, and the mortality rate is extremely high. [0003] In the teaching of coronary heart disease and myocardial infarction, the auxiliary teaching is mainly electrocardiogram. Since electrocardiogram involves the electrocardiographic phasor loop and four-dimensional space imagination, students generally report that they cannot intuitively understand the lesion area. For the deficiencies in this respect, we need to carry out technological innovation on the existing teaching aids. [0004] With the development of interventional...

AI Technical Summary

Problems solved by technology

[0004] With the development of interventional therapy for coronary heart disease and myocardial infarction, the mortality rate of this disease has dropped significantly. However, due to the lack of awareness of the severity of the disease, it is difficult for the patient and his family to understand the danger and danger of the disease when communicating with the patient. Necessity of emergency surgery, emergency interventional surgery is often refused
