Abstract

The invention discloses an atrial fibrillation demonstration model in the technical field of heartbeat models, which comprises a ventricular cavity cover, a closed cavity with a ventricular shape outside, a plurality of ventricular elastic strips uniformly and fixedly connected to the inner wall, a ventricular limiting shaft fixed inside, a ventricular contraction and expansion wheel rotatably mounted on the ventricular limiting shaft, and a ventricular contraction and expansion wheel rotatably mounted on the ventricular contraction and expansion wheel. The other ends of the ventricular elastic strips are fixedly connected with the ventricular contraction and expansion wheel, the rhythm of the heartbeat can be simulated, contraction and expansion of the ventricle and the atrium of the heartbeat can be displayed, and the device is specially used for displaying the rhythm of the atrial fibrillation, is used for simulating the heartbeat of different rhythms, and can perform visual simulation display on the atrial fibrillation. The heartbeat rhythm during arrhythmia can be displayed through various different atrial and ventricular beating rhythms, meanwhile, beating simulation can be conducted according to different atrial and ventricular proportions, manufacturing is easier, displaying is more visual, and carrying is more convenient.

Description

technical field

[0001] The invention relates to the technical field of heart beating models, in particular to an atrial fibrillation demonstration model. Background technique

[0002] The main function of the heart is to provide power for the flow of blood and move it to all parts of the body. The human heart is located at the lower left of the middle of the chest cavity, about the size of a fist, and weighs about 250 grams. Women's hearts are usually smaller and lighter than men's.

[0003] The human heart is shaped like a peach, located on the diaphragm, between the two lungs, and to the left. The human heart is in the middle of the chest cavity, slightly to the lower left, in a conical shape, about the same size as a person's fist, and has four cavities inside. chambers, the upper two are the atria and the lower two are the ventricles. The diastole and contraction of the atria and ventricles move blood around the body.

[0004] A contraction and relaxation of the hear...
