Description

Technical Field

[0001] This application belongs to the field of hemodynamic simulation technology, specifically a cardiovascular hemodynamic simulation device. Background Technology

[0002] Hemodynamics is the science of blood deformation and flow. It studies the flow and deformation of blood and blood vessels, explores the effects of blood and plasma viscosity on the body, and studies hemodynamics. It has a progressive effect on cardiovascular and cerebrovascular surgery and interventional treatment. When studying hemodynamics, the dynamics of blood flow in blood vessels are usually simulated to provide learners with a better intuitive understanding of cardiovascular blood flow.

[0003] For example, CN221782847U discloses a cardiovascular hemodynamic simulation device, including a simulated heart. The simulated heart has a first cavity in its upper part, with compression plates placed at both the top and bottom. An air bladder is located on the side of the two sets of compression plates that are close to each other, and connecting blocks are welded to the sides of the two sets of compression plates that are far apart. A pressing plate is welded to the top surface of the upper connecting block. The simulated heart has a second cavity in its lower part, with a support base welded to the bottom inner wall of the second cavity. A drive motor is bolted to the top surface of the support base, and an eccentric wheel is installed at the output end of the drive motor. This cardiovascular hemodynamic simulation device, by incorporating a drive motor, eccentric wheel, and air bladder, can simulate the contraction and relaxation of the heart. The contraction and relaxation of the air bladder simulates the heartbeat, thereby achieving the purpose of simulating cardiovascular hemodynamics.

[0004] However, in this application, the cardiovascular hemodynamics simulation device does not have four atria in the simulated heart, which will affect the simulation results. Utility Model Content

[0005] The purpose of this application is to provide a cardiovascular hemodynamic simulation device in order to solve the aforementioned problem of simulating heart structure.

[0006] The technical solution adopted in this application is as follows: A cardiovascular hemodynamic simulation device includes a simulated heart body, in which a right atrium, a left atrium, a left ventricle and a right ventricle are arranged sequentially inside the simulated heart body, a simulated wall is arranged between the right atrium, the left atrium, the left ventricle and the right ventricle, and an airbag is arranged inside the right atrium, the left atrium, the left ventricle and the right ventricle, and a pressing plate is arranged at the top of the right atrium, the left atrium, the left ventricle and the right ventricle.

[0007] By adopting the above technical solution and setting up the right atrium, left atrium, left ventricle, and right ventricle, it not only helps to understand the specific functions of each heart structure and their roles in blood circulation, but also enables students and medical professionals to better grasp the physiological mechanisms of the heart and related pathological states, and improve their overall understanding of the cardiovascular system. The simulated wall can effectively separate the right atrium, left atrium, left ventricle, and right ventricle, while the setting of the compression plate and airbag facilitates the simulation of heartbeat in this structure.

[0008] In a preferred embodiment, the pressing plate is connected to a limiting plate at one end inside the right atrium, left atrium, left ventricle and right ventricle, and the bottom end of the airbag is provided with a squeezing plate.

[0009] By adopting the above technical solution, and with the addition of other structures such as the pressure plate and airbag, it is possible to simulate the beating of the heart by using the right atrium, left atrium, left ventricle and right ventricle.

[0014] In a preferred embodiment, a connecting trachea is connected to the outer surface of the simulated heart body, the other end of the connecting trachea is connected to a pressure sensor, and an air bladder is connected to the connecting trachea inside the simulated heart body.

[0015] By adopting the above technical solution, the structure can easily monitor the blood pressure inside the simulated heart body by using a pressure sensor in conjunction with a connecting trachea and an air bladder.

[0016] In a preferred embodiment, a simulated superior vena cava is disposed above one side surface of the simulated heart body, and a simulated inferior vena cava is disposed on the surface of the simulated heart body corresponding to the surface below the simulated superior vena cava.

[0017] By employing the above technical solutions, simulating the superior vena cava, which is responsible for transporting deoxygenated blood from the head, neck, upper limbs, and part of the chest back to the right atrium, can help understand how blood returns from the whole body to the heart; simulating the inferior vena cava, which is responsible for transporting deoxygenated blood from the lower limbs, abdomen, and pelvis back to the right atrium, can demonstrate how deoxygenated blood enters the heart through the inferior vena cava.

[0018] In a preferred embodiment, a simulated aorta is fixedly disposed on the surface of the simulated heart body, and simulated pulmonary arteries and simulated pulmonary veins are disposed on both sides of the simulated aorta on the surface of the simulated heart body.

[0019] By employing the above technical solutions, the simulated aorta is the main artery that transports oxygenated blood from the left ventricle to all tissues of the body; the simulated aorta serves to demonstrate the process of the heart pumping blood and how blood flows through the aorta to the body; the simulated pulmonary artery transports carbon dioxide-containing venous blood from the right ventricle to the lungs for gas exchange, and the presence of the simulated pulmonary artery allows students to observe how the right ventricle pumps blood to the lungs; the simulated pulmonary vein is responsible for transporting oxygenated blood returning from the lungs back to the left atrium, and the simulated pulmonary vein serves to demonstrate how oxygenated blood enters part of the heart and provides a foundation for learning about the integrity of blood circulation.

[0021] In this application, by setting up the right atrium, left atrium, left ventricle, and right ventricle, it not only helps to understand the specific functions of each heart structure and their roles in blood circulation, but also enables students and medical professionals to better grasp the physiological mechanisms of the heart and related pathological states, and improve their overall understanding of the cardiovascular system. The simulated wall can effectively separate the right atrium, left atrium, left ventricle, and right ventricle, while the setting of the compression plate and airbag facilitates the simulation of heartbeat in this structure.
