Introduced respectively below.
1. infrared oxygen saturation monitor module and and infrared rhythm of the heart module
Infrared oxygen saturation monitor module is by adopting Non-Destructive Testing, and when utilizing the institute of the hemocyte in blood oxygen concentration different, to can pass through, HONGGUANG is different with the absorbing ability of infrared light to be detected, and then uses corresponding computational methods to obtain blood oxygen concentration.
Along with the contraction diastole of heart, periodic one one contracting of aorta, pressure is propagated from riser region to distal aorta and branch thereof with the form of ripple, forms pulse wave.In the communication process of pulse wave, due to the difference of cardiovascular status, pulse wave, by by reflection in various degree and refraction, can reflect the physiologic informations such as cardiovascular Peripheral resistance and vessel wall elasticity.
According to principle of hemodynamics, when blood vessel distortion is not too large, in one-period, the time dependent waveform of Ink vessel transfusing blood stream pressure will waveform similarity time dependent with vessel radius.Utilizing pulse wave strong for blocking infrared light ability during peak value, through the principle that infrared light ability is weak when pulse wave is valley, after the voltage differential signal utilizing amplifier that this is small amplifies, just can be recorded to time dependent curve of beating, be heart rate.
Blood oxygen concentration measuring principle is introduced:
The present invention normally obtains metrical information with the finger tip of people.The finger of people is a line and staff control, and HONGGUANG and infrared light finger, produce a constant specific absorbance A by the arterial blood of skin, muscle, skeleton, blood capillary, vein blood vessel and diastole.By heartbeat, arterial blood fills and causes capacity of blood vessel to change thus what form that pulsating quantity produces is the absorptance of respective change therewith .When the constant light with two kinds of specific wavelengths when irradiating finger, use Lambert-Beer law, can derive:
（1）
In formula: α 1, β 1the HbO corresponding to HONGGUANG 2(HbO2 Oxyhemoglobin), Hb(reduced hemoglobin) specific absorbance; α 2, β 2the HbO corresponding to infrared light 2(HbO2 Oxyhemoglobin), Hb(reduced hemoglobin) specific absorbance; with be respectively human body that linear light measuring circuit records to the absorbance variable quantity of HONGGUANG, infrared light.
