Display device for coronary atherosclerosis model

Abstract

The invention relates to the technical field of display devices, in particular to a display device for a coronary atherosclerosis model, which comprises a heart main body and a coronary artery demonstration main body, the coronary artery demonstration main body comprises a simulated coronary artery blood vessel which is arranged in the coronary sulcus of the heart main body, two ends of the simulated coronary artery blood vessel are respectively connected with the stretching pieces, and the simulated coronary artery blood vessel comprises an outer tube and an inner tube; the elastic bags are arranged between the inner tube and the outer tube in a penetrating mode, adjusting films are arranged at the communicating positions of the elastic bags and the inner tube, and a plurality of through holes are formed in the adjusting films; a regulating part is arranged at the communicating position of the elastic bag body and the outer pipe and comprises a suction part and an auxiliary part. The simulation circulation body is arranged in the inner pipe; and an auxiliary learning piece is filled between the inner pipe and the simulation circulation body. The device is designed according to the occurrence principle of coronary atherosclerosis, simulation of coronary atherosclerosis is realized through the coronary artery demonstration main body, and the demonstration and learning effects are improved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a display device for coronary atherosclerosis models. Background technique [0002] Atherosclerosis is the most common and important type of arteriosclerosis, which is characterized by lipid deposition in the intima of affected arteries, accumulation of complex carbohydrates, followed by fibrous tissue hyperplasia and calcium deposition, and arterial deposition. The lesions in the middle layer cause heart disease caused by myocardial ischemia, hypoxia or necrosis. The disease mainly involves large and medium-sized muscle-elastic arteries, most commonly the aorta, coronary arteries, and cerebral arteries, which often lead to serious consequences such as lumen occlusion or wall rupture and hemorrhage. Atherosclerosis that occurs in the coronary arteries is called coronary atherosclerosis (Coronary Atherosclerotic), which is the most common stenotic coronary artery disease,...

AI Technical Summary

Problems solved by technology

[0003] In order to allow medical students to understand coronary atherosclerosis, school teachers usually use display devices to show students coronary atherosclerosis models, which is convenient for students to learn, while the models in the prior art all show models of atherosclerosis results , at this time, it can only be shown intuitively to the students after hardening, but the occurrence process of coronary atherosclerosis cannot be known by the model. At this time, the effect of the teacher's model display is not obvious, so it is necessary A model display device that can simulate the process of coronary atherosclerosis, and use this model display device as a demonstration basis to explain and display, thereby improving learning efficiency
