摘要

这项工作提出了一种低成本的设备,用于评估可变孔板流量计(VOFM)在医疗机械通气应用。具体而言,该设备用于评估长度和厚度对矩形几何VOFM中不同流量的压降的影响。共对6个不同长度、不同厚度的vofm进行了评价。所有vofm均受到0 L.min - 1至90 L.min - 1的气流刺激,气流增量约为2 L.min - 1。用该装置进行的实验表明,在评估的vofm中,压降∆P与流量Q之间存在很强的关系,并且存在两个不同的区域:一个表现为非线性行为,另一个表现为线性行为。结果表明,长度的增加和厚度的减少导致灵敏度的提高。然而,减小传感器的横截面积以减轻传感器的非线性效应是必要的。

Design and Construction of a Device to Evaluate the Performance of Variable Orifice Flow Meters (VOFM)
This work presents a low-cost device for evaluating Variable Orifice Flow Meters (VOFM) used in medical mechanical ventilation applications. Specifically, the equipment was used to assess the impact of length and thickness on pressure drop for different flows in a rectangular geometry VOFM. A total of six VOFMs, with three different lengths and two different thicknesses, were evaluated. All VOFMs were stimulated with an airflow ranging from 0 L.min−1 to 90 L.min−1, with increments of approximately 2 L.min−1. The experiments conducted with the device showed a strong relationship between pressure drop ∆P and flow rate Q in the evaluated VOFMs, with two different zones: one exhibiting non-linear behavior and another showing linear behavior. The results suggest that increased length and decreased thickness lead to higher sensitivity. However, it is essential to reduce the cross-sectional area to mitigate nonlinear effects of the sensor.
