INSPECTION SYSTEM FOR A PULSATION, AN ANEMIC, A VEIN ELASTICITY AND AN OXYGEN SATURATION USING A SMART PHONE CAPABLE OF DISPLAYING BIO SIGNALS ON A DISPLAY DEVICE OF THE SMART PHONE

摘要

PURPOSE: An inspection system for a pulsation, an anemic, a vein elasticity and an oxygen saturation using a smart phone is provided to check bio signals in real time.;CONSTITUTION: A detecting part(10) comprises a light receiving part to detect light radiated from a light source. The detecting part detects the quantity of light transmitted when the light emitted from two LEDs having different wave lengths radiates to fingers. A wave filter(20) is connected to an output side of the detecting part to select frequency only within 0.05-5Hz with using a high pass filter and a low pass filter. An A/D converter(30) is formed in an output terminal of the wave filter to convert analog signals to digital signals. A smart phone(40) calculates bio signals with a micro controller by receiving data outputted from the A/D converter. The smart phone stores the measured data to an external memory of the smart phone and outputs the data using a display device.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Detecting part; (20) Wave filter; (30) A/D converter;
