Abstract

本发明公开了一种微流体眼压传感器，该微流体眼压传感器的角膜接触镜与眼角膜严密贴合，并传递眼压变化导致的眼角膜变形；微流体传感层设置于角膜接触镜的内部，中心与角膜接触镜的中心重合，呈螺旋线分布或者若干非闭合且相连接的同心圆分布，并且内圈直径大于瞳孔的直径，微流体传感层将眼压的变化转换为气液界面的位移变化，以此量化出眼压的变化，并通过显示通道中的树枝状结构对气液界面的最大位移进行记录，量化后可得到峰值眼压。上述微流体眼压传感器既可以直观判断患者的实时眼压，又可以在佩戴过程中方便地获取并记录下患者佩戴过程中的峰值眼压，解决了基于视觉传感的眼压传感器在夜间无法使用以及峰值眼压难以捕捉的问题。
