Embodiment Construction

[0037] In order to illustrate the technical content, structural features and specific detection methods of the present invention in detail, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0038] The invention provides a multifunctional combined simulated cycle test bench.

[0039] Such as figure 1 The experimental platform shown includes a ventricular pacemaker 1 , an elevating platform 2 , an arterial and venous return tank 3 , a body and a pulmonary circulation damper 4 , and a ventricular and atrium model 5 . The valve of the ventricular pacemaker 1 is connected with a conversion head with epoxy resin, connected with a hard rubber tube, and then connected with the ventricle and atrium model. The venous return tank 3 is connected with the atrium of the ventriculo-atrium model, and the body and pulmonary circulation damper 4 is connected with the right-angle tube at the upper end of the ventricle-atrium mode...

Abstract

The invention discloses a multifunctional combined simulation circulation experiment table, which belongs to the field of biomedicine and comprises a heart model containing left and right ventricles and atriums, a body and pulmonary circulation model containing vascular compliance and resistance, a ventricular pulsation model and an experiment table base. The multifunctional simulation circulation experiment table can effectively solve the problems that a traditional simulation circulation experiment table is single in purpose, the ventricular diastole and contraction degree cannot be quantitatively controlledthrough design of all models, and a heart frank-starting mechanism is considered. Meanwhile, hemodynamic experiments of a single heart and double heart auxiliary device and a total artificial heart under different physiological conditions can be realized, and a test platform is provided for a heart valve, an ECMO and a blood pump of an artificial heart-lung machine system.

Description

technical field [0001] The invention belongs to the experimental technical field of biomedical ventricular assist devices, and in particular relates to a multifunctional combined simulated circulation test bench. Background technique [0002] In recent years, the incidence of heart failure in the elderly population has been increasing, and it has become one of the main reasons that threaten the quality of human life and even cause human death. In the absence of donors, patients with severe heart failure can choose to receive left ventricular assist device, right ventricular assist device, double heart assist device or total artificial heart as a means of treatment or transition to heart transplantation according to the type and degree of heart failure. [0003] During the development and production of ventricular assist devices and total artificial hearts, the simulated circulation test bench is an important tool for evaluating the hemodynamics of the device before animal ex...
