Non-invasive blood albumin level monitor

Abstract

------11 / 11 / 2568------(OCR) The OCR 10KL is a non-invasive blood albumin level monitor used for measuring blood albumin concentration without invasiveness. The device uses two rechargeable 3.7V lithium polymer batteries. Inside, it contains a UV LED with a wavelength of 280 nanometers as the light source, as this is the light absorbed by albumin, and a green LED with a wavelength of 530 nanometers as the backlight. A photodiode sensor receives the residual light energy not absorbed by albumin and converts it into an electrical signal. This signal is then sent to an internal signal conversion circuit and processor. A microcontroller processes the signal and displays the albumin concentration as a number in grams per deciliter (g / dL) on the device's OLED display. ------------ OCR 07AP The non-invasive blood albumin monitor is used to measure blood albumin concentration levels without invasiveness.

Inside the device (1) are the electrical circuits: the signal detection circuit using a photodiode, the photodiode receiving the UV light energy remaining after the albumin absorption.It receives green light energy and converts both light energy into electrical current. The electrical current from both light sources is then sent to a voltage converter circuit. The resulting voltage is very small, so an amplification circuit is used to amplify the voltage signal to a larger size, and a frequency filtering circuit is used to filter out noise, leaving only the signal with the desired frequency. After that, the resulting signal, which is an analog signal, is converted into a digital signal by a microcontroller, which performs the function of converting the analog signal to a digital signal and processing the signal.
