Adjustable human body aorta vessel model device

Abstract

The invention relates to an adjustable human body aorta vessel model device. A aorta primary loop, three branch brachiocephalic trunk arteries of aortic arches, left common carotid artery and left subclavian artery are respectively provided with a pressure regulator (with built-in pressure gauge and regulating valve) which can regulate the loop pressure by regulating the vessel diameter size; an adjustable liquid heater and a pressure gate control channel are arranged in a liquid storage pool and can control the liquid in the pool to exchange with the outside according to the pressure magnitude; the aorta primary loop is connected with a vessel bypass in parallel; and the vessel bypass is provided with a pressure gate control channel which can automatically regulating the internal pressure in the whole vessel model. The invention can respectively regulate the pressure, temperature and circulation volume in the aorta loop to simulate the blood circulation and dynamic blood variations of human aorta under physiologic or pathological conditions in the aorta model in a more realistic way, thereby laying the foundation for clinical and scientific research related studies.

Description

technical field [0001] The invention relates to the relevant technical field of medical equipment, in particular to a human body aortic vessel model device with adjustable pressure, temperature and circulation capacity. Background technique [0002] With the improvement of living standards and the development of medical technology, the average life expectancy of Chinese people has been significantly prolonged, and the incidence of aortic degenerative disease has increased. Coupled with the improvement of medical imaging technology, the clinical incidence of aortic disease has also increased significantly. The need for clinical treatment has increased. Traditional treatment methods require thoracotomy or laparotomy for artificial vascular replacement. The trauma is huge, and the elderly and patients with aortic disease with many coexisting diseases are often difficult to tolerate, and the surgery-related complication rate and mortality rate are extremely high. The newly deve...

AI Technical Summary

Problems solved by technology

After the blood vessel model and circulation simulation device are started, the pressure, temperature and liquid volume of the simulated blood in the aorta and branch arteries will not change. When performing the experiment and detection of the intracavitary device, of course, it cannot simulate the intervention of the experimental device into the arterial system. The changes in pressure, temperature and volume caused by these changes, as well as the impact of these changes on new intracavity devices, make it impossible to conduct hemodynamic studies

[0005]Therefore, the existing blood vessel models and blood circulation simulation devices cannot simulate the hemodynamic changes in the human aorta, let alone meet the needs of clinical research and new technology research and development
