Embodiment Construction

[0032] It should be noted that the features of the present application and the features in the embodiments in the present application can be combined with each other in the case of an unable conflict. The present invention will be described in detail below with reference to the accompanying drawings.

[0033] A rigid structure is simulated using a rigid structure using a rigid structure, such as organic glass as a ventricle to simulate cardiac motion, which is unable to simulate natural heart myocardium shrinkage, and there is no alternative Shrink, alternate diastolic phase. The arterial pipe is used to use ordinary silica gel hoses so that the arterial pipeline cannot simulate the human blood vessel tension, which is far from the actual human application. The valve application also uses a mechanical one-way valve, which produces a vibration, leakage, and deformation. And the test system can also simulate the valve condition of the patient.

[0034] So, if figure 1 As shown, embo...

Abstract

The invention provides a test system for a ventricular assist device. The test system for the ventricular assist device comprises a first pipeline; the left heart simulation system comprises a second pipeline, and a left atrium simulation assembly, a mitral valve simulation valve, a left ventricle simulation assembly, an aortic valve simulation valve, an aorta simulation assembly, a first flow meter and a first resistance valve which are sequentially arranged on the second pipeline; the right heart simulation system comprises a third pipeline, and a right atrium simulation assembly, a tricuspid valve simulation valve, a right ventricle simulation assembly, a pulmonary artery valve simulation valve, a pulmonary artery simulation assembly and a second resistance valve which are sequentially arranged on the third pipeline; and the switching device is used for communicating any two of the first pipeline, the second pipeline and the third pipeline, so that the test system for the ventricular auxiliary device has a systemic circulation mode, a right heart circulation mode and a full circulation mode. According to the technical scheme, the problem that in the prior art, an in-vitro test system of a ventricular auxiliary device is single in function is solved.

Description

Technical field [0001] The present invention relates to the field of medical devices and clinical applications, and in particular, a test system for a ventricular auxiliary device is involved. Background technique [0002] As the final stage of heart disease development, cardiac failure is irreversible, difficult to treat, high mortality, and cardiac transplantation as an effective treatment, but due to the shortage of heart donor, the difficulty of matching is unfortunately died. With the development of artificial heart technology, it has brought the hope of many heart failures. The development of the artificial heart technology is a ventricular auxiliary device, which can be used to implant the patient's heart, providing auxiliary blood circulation support for patients, thereby reducing the burden on the heart, facilitating the recovery of myocardium. The technique is divided into left ventricular auxiliary devices (LVAD) and right ventricular auxiliary devices (RVAD) have beco...
