摘要

准确测量流速是许多医疗应用的关键要求，如输液和药物输送系统。当前系统的一个主要缺点是传感器在低流量状态下的低分辨率。在本文中，我们提出了一种基于全息PIV/PTV的方法，该方法首次用于测量几nL/min范围内的流量。我们的方法需要一个非常简单的设置，将无透镜全息术与粒子测速相结合。对于70 - 200 nL/min范围内的流量，最高不确定性为5.6%(覆盖因子k=2)。这是一个开源项目;CAD设计和软件源代码可在https://github.com/gui-miotto/holovel上获得。

Holographic PIV/PTV for nano flow rates-A study in the 70 to 200 nL/min range.

Accurately measuring flow rates is a key requirement in many medical applications such as infusion and drug delivery systems. A major drawback of current systems is the low resolution of the sensors in the low flow rate regime. In this article, we present a method based on Holographic PIV/PTV that has been used for the first time to measure flow rates in the range of a few nL/min. Our method requires a very simple setup that combines lensless holography with particle velocimetry. For flow rates in the 70 to 200 nL/min range, the highest uncertainty was 5.6% (coverage factor k=2). This is an open-source project; the CAD designs and software source code are available at https://github.com/gui-miotto/holovel.
