Noninvasive blood component concentration measuring apparatus and control method of non-invasive blood component concentration measuring apparatus

摘要

Problem to be solved: to provide a non-invasive blood component concentration measuring apparatus capable of measuring the concentration of blood components accurately without taking blood.A non-invasive blood component concentration measuring device h for measuring the concentration of blood components in the organismA light emitting device 111 for irradiating incident light to a test site of a pulsating organism andA light receiving element 112 for receiving transmitted light transmitted through a test siteA first sonic oscillator 113a for firing an incident sound wave to an inspection siteA first sound receiver 114A receiving a reflected sound reflected at the surface of the test siteAn MPU 21a for calculating the concentration of blood componentsEquipped withMPU 21aSignal intensity change by pulsation of transmitted light measured by light receiving element 112 Δ V andVolume change of test site by pulsation measured by incident acoustic wave and reflected sound wave Δ A,The concentration of the blood component is calculated based on this.Diagram
