Embodiment Construction

[0034] The structure of the system is described in detail below in conjunction with the accompanying drawings:

[0035] see figure 1 , the system has four test chambers, one arterial cavity SA, systemic vein cavity SV, pulmonary artery cavity PA and pulmonary vein cavity PV, two adaptive damping valves, two manually adjustable damping valves, four pressure testing devices p1, p2, p3, p4, two flowmeters, and associated connecting flow paths, where:

[0036] The four interfaces of the artificial heart are respectively connected to the corresponding systemic artery cavity input interface SAI, systemic vein cavity output interface SVO, pulmonary artery cavity input interface PAI, and pulmonary vein cavity output interface PVO;

[0037] The test liquid flows into the systemic circulation vena cava input interface SVI through the flow path outlet SAO of the systemic arterial cavity through the flow path of the simulated systemic circulation;

[0038] The test liquid flows into the...

Abstract

The present invention provides one kind of extracorporeal simulated circulation test system for artificial heart. The system consists of four test cavities and related connecting flow path, test equipment and flow path devices. By means of its adaptive damping valve and corresponding communication structure combined with cavity compliance and manual damping valve structure, the system characterizes the dynamic response characteristic of human body artery vessels for regulation based on initially selected physiological parameters to adapt the tested physiological environment. The system has manufacture uniformity, small integral size and variable damping, and is used for testing the power system of artificial heart.

Description

technical field [0001] The invention relates to a test system for performing an in vitro simulated cycle test on an artificial organ (artificial heart). Background technique [0002] As a kind of artificial organ, the artificial heart provides a solution for patients who need organ transplantation but cannot obtain a heart donor. However, the detection of the artificial organ power system must be carried out with the help of its extracorporeal circulation simulation test equipment. [0003] At present, its test system is basically designed based on the principle of elastic cavity, but based on different implementations, there are often two main types of systems, one is based on simple cavity simulation, and is fitted through a simple pipeline loop. The data is obtained by trial and error, which is simple, but lacks precise condition setting. [0004] In addition, it is similar to the electromechanical hydraulic system used in the paper published b...
