人工左膝关节

Artificial Left Ventricle

Saeed Ranjbar, Tohid Emami Meybodi, Mahmood Emami Meybodi

摘要:

这种人工左心室是基于一个简单的圆锥假设形状的左心室,它的运动是由附加在其壁上的压缩弹性管来实现的,这些压缩弹性管被认为是每个节点上的电点,这些压缩管在左心室的心肌中起着肌纤维的作用。这些弹性管具有螺旋形状并且动态地作用于这些螺旋带。在本发明中,我们给出了这种人造左心室构造的算法,当然,通过使受益人使用传感器来获得这种效果来观察LV中的血流的效果,类似于生命门问题。主要问题是评估弹性体(左心室)和流体(血液)之间相互作用的功率。本发明的主要目的是表明人工心脏不仅仅是泵,而是LV壁的机械建模及其与其中血液的相互作用(血液运动建模)可以引入接近于自然心脏的人工心脏。

英文摘要:

This Artificial left ventricle is based on a simple conic assumption shape for left ventricle where its motion is made by attached compressed elastic tubes to its walls which are regarded to electrical points at each nodal .This compressed tubes are playing the role of myofibers in the myocardium of the left ventricle. These elastic tubes have helical shapes and are transacting on these helical bands dynamically. At this invention we give an algorithm of this artificial left ventricle construction that of course the effect of the blood flow in LV is observed with making beneficiary used of sensors to obtain this effecting, something like to lifegates problem. The main problem is to evaluate powers that are interacted between elastic body (left ventricle) and fluid (blood). The main goal of this invention is to show that artificial heart is not just a pump, but mechanical modeling of LV wall and its interaction with blood in it (blood movement modeling) can introduce an artificial heart closed to natural heart.
