| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 107 === The principle axis of this experiment is measuring blood typing by the fastest and convenient way. In the study, we design the portable electrical measuring instrument in order to provide accurate reading to the relief worker at the first time, and help to respond quickly. Avoid lengthy inspection process and lead to delay in medical treatment. However, the basic inspection process now requires 1.5~3ml of blood, and goes through the complicated process of centrifugation, reagent addition. The result is finally told by relief worker. This paper proposes a blood-type identification microfluidic system, which also includes the necessary and convenient elements for disaster sites. The required sample is only 0.3% of the general blood test, and the degree of agglutination of red blood cells can be told by dropping 5ul of blood.
The blood type identification microfluidic channel comprises a blood injection tank, a reagent injection tank, meter chamber, capillary valve, a mixed channel and a Reaction chamber, which can achieve the quantitative and uniform mixing effect of the reagent and the blood, and also combine the interdigitated electrode and the Reaction chamber to measure the degree of blood typing. In addition, the instrument is also compared with the commercial machine in the industry, and verified by the samples of 10 voluntary test subjects. Although the precision of handy tools can’t equal to commercial machines, the testing results are still highly valuable for reference .
