Abstract

The purpose of this project is to develop a method to scan centrifuge tubes in a rack to get an estimate of hematocrit level in blood. Work has been done on design requirements, research on blood physics, research on possible detecting methods: ultrasound and infrared light, and initial proof of concept experiments with ultrasound and infrared. Infrared was selected at the beginning of spring 2018. More proof of concept experiments using a laser pointer, a light capturing camera, and a Parallax microcontroller for detection of oil-water boundary were carried out in the spring. The experiments prove that there is possibility to use this concept for plasma-red blood cells boundary detection. A method for hematocrit estimation is proposed based on the testing results. Next steps include developing experiments with infrared light and blood, and prototyping and testing the device.
