检测胃动力功能的生物电阻抗法

The biology resistance method of examination stomach power function

在胃排空或胃收缩、蠕动时,由于胃的形态、容积及其内容物组成情况的改变较大,电特性变化非常明显,变化规律与胃动力学状况相对应,相关性强。采用生物阻抗方法可以实现无创、高灵敏、准确地提取与胃动力学状况相对应的电特性及其变化信息。在介绍了胃动力功能及其检测方法的基础上,着重阐述了检测胃动力的电阻抗方法的发展动态,技术关键及其存在的问题。

when the stomach evacuates or the stomach contracts, wriggles, the change of its electricity characteristic is extremely obvious, the change rule corresponds to the stomach dynamics condition, and they are relevant because the change of stomach shape, volume and composition situation of its containing the matter are big. Using the biological resistance method, we can hurtlessly, high delicately and accurately withdraw the electricity characteristic and change information that corresponds with the stomach dynamics condition. In this article, we introduce the stomach power function and its examination method, and elaborate the development tendency, the technical key and the existence question of electricity resistance method to examine stomach power.
