A device for continuously measuring, at constant pressure, the filtration resistance of different liquid suspensions is described. It is made up of two main parts: flowmeter system and electronic circuit. The flowmeter consists of a capillary tube and a sensitive pressure transducer, and has a time response of 100 ms and a linearity of +/- 1% from 1 uls-1. The electronic part allows the calculation and recording of flow versus time and filtration resistance versus the volume which passes through the filter. Principle, technical characteristics of the system and examples of recording with several Red Blood Cell populations are reported.
描述了一种用于在恒定压力下连续测量不同液体悬浮液过滤阻力的装置。它由两个主要部分组成：流量计系统和电子电路。流量计由一根毛细管和一个灵敏的压力传感器组成，时间响应为100毫秒，流量在1微升/秒至100微升/秒范围内时线性度为±1%。电子部分可以计算并记录流量随时间的变化以及过滤阻力随通过过滤器的体积的变化。报告了该系统的原理、技术特性以及使用几种红细胞群体进行记录的示例。
