Fig. 8 shows that a kind of flow diagram for oxygen saturation monitor method that the embodiment of the present invention three provides, this method are applicable in
The oxygen saturation monitor device described in above-described embodiment, includes the following steps：
The the first detection optical signal and wavelength that S101, oxygen saturation monitor device send out that wavelength is 660nm to human body are 940nm's
Second detection optical signal.
When oxygen saturation monitor device is used or is switched on again for the first time, oxygen saturation monitor device acquiescence human body is currently at normally
Blood oxygen concentration or higher blood oxygen concentration, i.e. the first light emitting group work of oxygen saturation monitor device at this time, the second light emitting group is not
Work, first it is micro-led to human body send out wavelength be 660nm first detection optical signal, the second miniature light-emitting diodes
Pipe sends out the second detection optical signal that wavelength is 940nm to human body.
First it is micro-led to human body send out wavelength be 660nm first detection optical signal and second it is miniature shine
The method that diode sends out the second detection optical signal that wavelength is 940nm to human body is specifically as follows：First miniature light-emitting diodes
Pipe and the second micro-led periodically alternately send successively detect optical signal.
S102, oxygen saturation monitor device receive the first light signal fed back and the second light signal fed back.
First light signal fed back is converted to the first digital signal by S103, oxygen saturation monitor device, and the second feedback light is believed
Number be converted to the second digital signal.
First detection optical signal and the second detection optical signal are after human body reflects, by the first filtering of oxygen saturation monitor device
Device is received ambient light rejection by the micro photo electric reception pipe of oxygen saturation monitor device.Wherein, the first light signal fed back is first
Optical signal of the optical signal after human body reflects is detected, the second light signal fed back is light of the second detection optical signal after human body reflects
Signal.
Then, the second filter of oxygen saturation monitor device and the first light signal fed back of amplifier pair and the second light signal fed back
It is filtered amplification, and by analog-digital converter, is converted to the first digital signal and the second digital signal.
S104, oxygen saturation monitor device generate the first monitoring result according to the first digital signal and/or the second digital signal.
Wherein, the first monitoring result is used to indicate the oxygen content of blood of human body.
After obtaining the first digital signal and the second digital signal, the processor of oxygen saturation monitor device is believed according to the first number
Number and/or the second digital signal, generate the first monitoring result.
Further, the stream of another oxygen saturation monitor method of the offer of the embodiment of the present invention three is provided in conjunction with Fig. 8, Fig. 9
Journey schematic diagram further includes after step s 104：
S105, oxygen saturation monitor device confirm the magnitude relationship of the first monitoring result and the first preset value and the second preset value.
Wherein, the first preset value is more than the second preset value.Specifically, the first preset value is relatively low (inferior health) blood oxygen of human body
The critical value of content, the second preset value are the critical value of improper (unhealthy) oxygen content of blood of human body.
Since the first monitoring result (i.e. the current oxygen content of blood of human body) currently obtained is possible to and current oxygen saturation monitor
The working condition of device selection is inconsistent.Therefore, oxygen saturation monitor device need to confirm the first monitoring result and the first preset value and
The magnitude relationship of second preset value.
If S106, the first monitoring result are more than the second preset value, and are less than the first preset value, then oxygen saturation monitor device stops
The first detection optical signal that wavelength is 660nm and the second detection optical signal that wavelength is 940nm are sent out to human body, and is sent out to human body
Go out the third detection optical signal and send out the 4th detection optical signal that wavelength is 890nm to human body that wavelength is 735nm.
If the first monitoring result is more than the second preset value, and is less than the first preset value, then it represents that current human's oxygen content of blood
It is relatively low but not up to unhealthy, or even the case where influence life security.Trace of albumin under the state in blood of human body can be to blood
The measurement result of oxygen monitoring device has an impact, it is therefore desirable to stop sending out the first detection light letter that wavelength is 660nm to human body
Number and wavelength be 940nm second detection optical signal, oxygen saturation monitor device control the first light emitting group do not work, the second light emitting
Group work, third it is micro-led to human body send out wavelength be 735nm third detect optical signal, the 4th it is miniature shine two
Pole pipe sends out the 4th detection optical signal that wavelength is 890nm to human body.
Third it is micro-led to human body send out wavelength be 735nm third detect optical signal and the 4th it is miniature shine
The method that diode sends out the 4th detection optical signal that wavelength is 890nm to human body is specifically as follows：The miniature light-emitting diodes of third
Pipe and the 4th micro-led periodically alternately send successively detect optical signal.
S107, oxygen saturation monitor device receive third light signal fed back and the 4th light signal fed back.
Third light signal fed back is converted to third digital signal by S108, oxygen saturation monitor device, and the 4th feedback light is believed
Number be converted to the 4th digital signal.
Third detects optical signal and the 4th detection optical signal after human body reflects, by the first filtering of oxygen saturation monitor device
Device is received ambient light rejection by the micro photo electric reception pipe of oxygen saturation monitor device.Wherein, third light signal fed back is third
Optical signal of the optical signal after human body reflects is detected, the 4th light signal fed back is light of the 4th detection optical signal after human body reflects
Signal.
