Abstract
An optical method for hematocrit measurement is presented. The sensor, designed and developed by authors, consists of a spectroscopic set-up and a microcontroller. The work of the sensor is based on measurement of intensity of two selected spectral bands. Tests confirmed the ability of the sensor to determine the hematocrit level with appropriate measurement accuracy. Measurement results can be transmitted via wireless module to the monitoring center and analyzed by professionals.
Keywords
Hematocrit measurement; Spectroscopy; Blood analysis
Highlights
– The designed spectroscopic system is cheap and accurate.
– The downside of this system is undoubtedly the measurement speed because one measurement takes from 30 to 60 s.
– Shown HCT measurement level range is the result of blood samples available to test.
