A heart chamber simulator driving mechanism

Abstract

The invention discloses a heart chamber simulator driving mechanism, which comprises a motor, a speed reducer, a crank shaft connecting rod mechanism, a linear guide rail and a piston air cylinder, wherein an output end of the motor is connected with an input shaft of the speed reducer, an output shaft of the speed reducer is connected with one end of the linear guide rail through the crank shaft connecting rod mechanism, the other end of the linear guide rail is connected with the piston air cylinder through a shaft coupler, an air hole is formed in the side wall of the piston air cylinder, and the air hole is connected with a heart chamber simulator through a pipeline. The driving mechanism belongs to a driving mechanism capable of providing a pulsation type power source for the heart chamber simulator according to the set frequency and discharge capacity. The driving mechanism has the advantages that the pulsation feature of the beating of the heart chamber simulator can be realized, meanwhile, the beating frequency and the discharge capacity can be respectively regulated, and the human body heart beating process is more really simulated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a driving mechanism of a heart chamber simulator. The drive mechanism is used to assist in the research and development of minimally invasive intracardiac interventional medical devices, blood circulation and medical imaging research and training doctors. Background technique [0002] The driving mechanism of the heart chamber simulator is a driving mechanism used to drive the heart chamber simulator to perform regular movements according to the required method. It is a key technology for simulating the beating of the human heart and blood circulation. It is very important for the development of minimally invasive cardiac interventional medicine. is of great significance. [0003] At present, most heart simulators are static medical models for medical teaching, without power-driven parts, and cannot reflect the dynamic characteristics of blood circulation. Some high...

Problems solved by technology

[0004] In order to overcome the problem that the existing heart simulator cannot correctly reflect the corresponding relationship between the pressure during systole and diastole, and the deformation caused by external loading cannot reflect the overall contraction and deformation of the myocardium, so that the heart simulator cannot truly reflect the heart beating process. A driving mechanism of a heart chamber simulator, the driving mechanism can simulate the pulsating beating process of the human heart by adopting an intermittent working method, which can not only satisfy the correct pressure relationship, but also reflect the overall deformation process of the myocardium, thereby realistically reflecting heart beat process
