Biological information measurement and collection device main body

Abstract

This article is a main body of a biological information measurement and collection device used to measure and collect biological information such as arterial blood oxygen saturation, mixed blood oxygen saturation, oxygenation, and the amount of deoxygenated hemoglobin by being worn on the head (forehead) of a subject or patient. When it is worn on the head of a subject or patient and the switch is pressed to enter the operating state, the reflected light that has passed through the living body, such as near-infrared light emitted by the light source unit, is received by the light receiving unit, and the received light signal is analyzed and output as information such as arterial blood oxygen saturation. Turn the dial to tighten and fix the belt on the head, and turn it in the reverse direction to loosen and remove the belt.
