| Summary: | 碩士 === 淡江大學 === 水資源及環境工程學系碩士班 === 94 === In order to extend lifetime of mechanical heart valve (MHV), the geometric shape of hinge’s rotational part is an important key point. The study chose center-of gravity position, geometric shape of hinge, stopper and kinetic mechanism, improvement for stop-back, old-moon-C-shaped pivot as parameters has been design in this study, and it is helpful for flowing throughout. The closing behavior of leaflet is utilizing broadside touch and back-stopper. Move-test and Pro/E Mechanism module were used to analysis the gap and interference between the leaflets and housing ring. The gap is related to agile degree, so over or less could involve its safety. Moreover, the study will provide all parameters used in this research for designing future generations of MHV.
