Device for showing cardiac souffle generation principle

Abstract

The invention discloses a device for showing a cardiac souffle generation principle. The device for showing the cardiac souffle generation principle is provided with an elongated flat plate and a shock wave device; a tough support A column is inserted in the left side of the shock wave device, and the head of the tough support A column is equipped with a first empty ball; a tough support B column is inserted in the right side of the shock wave device; the head of the tough support B column is equipped with a second empty ball filled with air, and the tough support A column, the tough support B column, the first empty ball and the second empty ball are the same in material; the first empty ball and the second empty ball have the same internal diameter and external diameter; and a receptor of the shock wave device is adhered to the surface right above a locally narrow transparent plastic pipe. Part of the transparent plastic pipe is narrow, turbulent flow is generated in the narrow position, subsequently shocks are generated, and are conducted to the shock wave device through the shock wave sound waves, and are then conducted to two ends of the elongated flat plate, and are heard by a doctor through an echometer. The device for showing the cardiac souffle generation principle is simple in structure, and visually displays the generation principle of cardiac souffle.

Description

technical field [0001] The invention belongs to the technical field of medical teaching aids, in particular to a device for displaying the principle of heart murmur generation. Background technique [0002] Heart murmur refers to the abnormal sound produced by the vibration of the wall, valve or blood vessel caused by the turbulent flow of blood in the heart or blood vessel during systole or diastole, in addition to heart sound and extra heart sound. At present, the explanations here in the medical teaching process generally take the form of oral descriptions or pictures, which is difficult for some students to understand. [0003] To sum up, the existing teaching of heart murmurs using words or pictures has difficulty in understanding, is not vivid, and reduces the teaching effect. Contents of the invention [0004] The purpose of the present invention is to provide a device for displaying the principle of heart murmurs, aiming at solving the problems that the existing h...
