The blood oxygen saturation value of human body.Specifically, green light is passed through between the green light chip of 520~540nm by using peak wavelength
Chip issues green light, due to the attenuation by absorption effect by finger tip integumentary musculature and blood, receives what chip 310 detected
Green intensity will weaken.Wherein skin, musculature etc. are to maintain the absorption of light invariable in entire blood circulation,
And the blood in skin, volume change under key role in pulsation.The most light absorptions of periphery blood volume when the heart contracts
Amount is also maximum, and the luminous intensity detected is minimum.And in diastole, exactly the opposite, the luminous intensity detected is maximum, therefore,
Receive the luminous intensity that chip 310 receives is in pulsating nature variation therewith, and then detects the heart rate of tested human body well.And by
In in blood, the absorptivity of green light is the largest, thus use peak wavelength between 520~540nm green light chip as
The heart rate of tested human body can be detected well by injecting light source, and the data detected are more acurrate.Further, in first substrate
On 210, peak wavelength is set between the dark red optical chip interval of 650~670nm of green light chip and peak wavelength of 520~540nm
Set, the dark red optical chip and peak wavelength of 650~670nm of peak wavelength between 930~950nm near infrared light chip chamber every setting
It sets, so that light wave is more evenly distributed, the optical signal for receiving the light wave that chip 310 receives is more acurrate, further, described first
Substrate 210 is the copper-clad plate of resin base or epoxy glass cloth laminated board, and three transmittings only can be set on the first substrate 210
Chip 220.By encapsulation green light chip, dark red optical chip, near infrared light chip and first substrate 210, green light is avoided well
Chip, dark red optical chip, near infrared light chip and first substrate 210 are damaged and influence the accuracy of measurement.Further, by
It is high in enclosing material flatness, and can be fitted closely with glass, almost without gap, therefore each chip can be avoided to issue well
Light between crosstalk.It is noted that the material that the enclosing uses is epoxy natural rubber and its blend, hydrogenation
Deng improvement nitrile rubber, polyurethane and carbon black mixture, it is mixed with any one of nano-metal particle and the resin of black toner.
Due to being tested the pulsation of human body, so that can constantly be changed by the light intensity that finger transmits.Pass through the calculation in single-chip microcontroller in this way
Method calculates, so that it may more accurately detect the heart rate of tested human body.
In one embodiment, the reception chip 310 is PD chip, and the PD chip is between 60~150mil's
PD chip is received after transmitting chip 220 emits by using PD chip as chip 310 is received by tested well
Remaining luminous intensity after human skin muscle and blood absorption, and the reception by continuing for some time, and by light
The optical signal of wave is converted to electric signal, then electric signal is converted to digital signal by AD converter, finally by single-chip microcontroller
Algorithm calculate the blood oxygen saturation value of tested human body.
In one embodiment, first substrate 210, the second substrate 300 are resin base copper-clad plate, since resin base covers copper
Plate have very high high glass transition temperature, the performances such as outstanding dielectric properties, low thermal expansion rate and good mechanical characteristics, therefore
It chooses the copper-clad plate of resin base and arranges line slot in resin base copper-clad plate as first substrate 210, and according to different needs, then
Each transmitting chip 220 is arranged with line slot interval, conducting wire is arranged in line slot, by the positive and negative of each transmitting chip 220
Pole is connect with the positive and negative anodes on the bonding wire functional areas in resin base copper-clad plate.The copper-clad plate of resin base is chosen as the second substrate 300,
And line slot is arranged in resin base copper-clad plate according to different needs, then reception chip 310 and line slot interval are arranged, and
Line slot is arranged in resin base copper-clad plate according to different needs, then reception chip 310 and line slot interval are arranged, online
Conducting wire is arranged in the slot of road, and the positive and negative anodes on the bonding wire functional areas on the positive and negative anodes and the copper-clad plate of resin base that receive chip 310 are connected
It connects.It is noted that receiving chip 310 and second makes production efficiency significantly essentially by using SMD paster type encapsulation
Promoted, realize automatic sorting and automatic packaging well, thus application end can directly upper chip mounter, production efficiency and yield
Biggish improvement is all obtained.
Further, since oxyhemoglobin, the reduced hemoglobin etc. in blood are shown not under different conditions
With the principle of optical absorption spectra, therefore the light of the chip sending different colours of different peak wavelengths is used, and the wavelength of the light emitted
It is required that oxyhemoglobin and reduced hemoglobin are greater than non-blood tissue to its absorption coefficient to the absorption coefficient of light, but
It not arrive greatly so that permeation parts are difficult to detect.It can be selected near 650nm, and the light near this wavelength is to oxyhemoglobin
Approximate maximum with the difference of reduced hemoglobin absorption coefficient, when blood oxygen saturation difference, blood is to the wavelength absorbing amount
Change most sensitive.
In one embodiment, bluetooth module is additionally provided in the tester ontology.By the way that tester is sandwiched in use
On the finger of person, transmitting chip uses finger as the transparent vessel for containing hemoglobin by transmitting incident light, then is turned by AD
Electric signal is converted to digital signal by parallel operation, under the control of single-chip microcontroller, carries out short-distance transmission by bluetooth module, using
Digital Signal Processing finally obtains blood oxygen saturation, by using bluetooth module, makes it possible to preferably pass measured data
It is defeated data to be collected into corresponding database, so can more accurately by compare come so that measurement result more
Accurately.
In conclusion it is restricted embodiment of the invention, all those skilled in the art that above embodiment, which is not,
The modification carried out on the basis of substantive content of the invention or equivalent deformation, in technology scope of the invention.
