| 摘要 |
The present invention relates to a biological blood flow measuring module, more particularly, a biological blood flow measuring module capable of measuring oxygen saturation and a pulsation regardless of the thickness of body skin. That is, an embodiment of the present invention comprises a plurality of light sources which are mounted on the front surface of a substrate and emit light with different wavelengths into a flood flow in the body skin; a sensor unit receiving light reflected from the blood flow in the skin; a protective cover which is positioned between the plurality of light sources and the sensor unit and prevents the light emitted from the light source from being directly received, wherein the plurality of light sources comprise at least one infrared ray for measuring the thickness of the body skin, and provided is the blood flow measuring module comprising a visible light emitting light with different wavelengths individually into a blood flow in body skin based on an amount of infrared rays measured at the sensor unit. |
