Measuring and monitoring hemorheological properties provide valuable insights into diseases. To effectively detect impaired blood, it is necessary to quantify the multiple properties. However, most of previous methods only single blood property. They require bulky expensive syringe pumps for precise on–off control. In this study, resolve several issues, a novel method measuring (fluidic resistance, viscosity, time constant, compliance coefficient, red cell [RBC] aggregation index, RBC sedimentation index) proposed by analyzing images in microfluidic channels, where transient flow induced portable air-compression pump. A device consists an inlet, test chamber joined main channel, reservoir. The outlet connected air damper, which contributes stopping promptly. fluid circuit model channels constructed estimating rate pressure channel. First, used obtain rheological glycerin solution (30%). normalized difference between reference value less than 4%. Subsequently, adopted differences medium (1× phosphate-buffered saline, dextran solution: 20 mg/ml) hematocrit (30%–60%). All exhibit substantial with respect medium. yields comparable results when compared methods. conclusion, can measure channels.
