Embodiment Three

Fig. 8 shows a schematic flowchart of a blood oxygen monitoring method provided by Embodiment 3 of the present invention, which is applicable to the blood oxygen monitoring device described in the above embodiment, and includes the following steps:

S101. The blood oxygen monitoring device sends a first detection light signal with a wavelength of 660nm and a second detection light signal with a wavelength of 940nm to the human body.

When the blood oxygen monitoring device is used for the first time or turned on again, the blood oxygen monitoring device defaults that the human body is currently in a normal blood oxygen concentration or a higher blood oxygen concentration, that is, the first light emission group of the blood oxygen monitoring device works at this time, and the second light When the emitting group is not working, the first miniature light emitting diode sends out a first detection light signal with a wavelength of 660nm to the human body, and the second microlight emitting diode sends out a second detection light signal with a wavelength of 940nm to the human body.

The method in which the first miniature light-emitting diode sends a first detection light signal with a wavelength of 660nm to the human body and the second microlight-emitting diode sends a second detection light signal with a wavelength of 940nm to the human body can specifically be as follows: the first miniature light-emitting diode and the second miniature light-emitting diode The light emitting diodes periodically and alternately send detection light signals.

S102. The blood oxygen monitoring device receives the first feedback optical signal and the second feedback optical signal.

S103. The blood oxygen monitoring device converts the first feedback optical signal into a first digital signal, and converts the second feedback optical signal into a second digital signal.

After being reflected by the human body, the first detection light signal and the second detection light signal pass through the first filter of the blood oxygen monitoring device to filter out the ambient light, and are received by the miniature photoelectric receiving tube of the blood oxygen monitoring device. Wherein, the first feedback optical signal is the optical signal of the first detection optical signal reflected by the human body, and the second feedback optical signal is the optical signal of the second detection optical signal reflected by the human body.

Wherein, the first preset value is greater than the second preset value. Specifically, the first preset value is the critical value of the low (sub-healthy) blood oxygen content of the human body, and the second preset value is the critical value of the abnormal (unhealthy) blood oxygen content of the human body.

Because the currently obtained first monitoring result (that is, the current blood oxygen content of the human body) may be inconsistent with the working state selected by the current blood oxygen monitoring device. Therefore, the blood oxygen monitoring device needs to confirm the relationship between the first monitoring result and the first preset value and the second preset value.

S106. If the first monitoring result is greater than the second preset value and less than the first preset value, the blood oxygen monitoring device stops sending the first detection optical signal with a wavelength of 660nm and the second detection optical signal with a wavelength of 940nm to the human body , and send a third detection light signal with a wavelength of 735nm to the human body and a fourth detection light signal with a wavelength of 890nm to the human body.

If the first monitoring result is greater than the second preset value and smaller than the first preset value, it means that the current blood oxygen content of the human body is low, but not unhealthy or even life-threatening. In this state, the trace amount of protein in human blood will affect the measurement results of the blood oxygen monitoring device, so it is necessary to stop sending the first detection optical signal with a wavelength of 660nm and the second detection optical signal with a wavelength of 940nm to the human body, blood oxygen monitoring The device controls the first light-emitting group to not work, the second light-emitting group to work, the third micro-LED to send a third detection light signal with a wavelength of 735nm to the human body, and the fourth micro-light-emitting diode to send a fourth detection signal with a wavelength of 890nm to the human body. light signal.

The method in which the third miniature light-emitting diode sends a third detection light signal with a wavelength of 735nm to the human body and the fourth microlight-emitting diode sends a fourth detection light signal with a wavelength of 890nm to the human body can specifically be as follows: the third miniature light-emitting diode and the fourth miniature light-emitting diode The light emitting diodes periodically and alternately send detection light signals.

S107. The blood oxygen monitoring device receives the third feedback optical signal and the fourth feedback optical signal.

S108. The blood oxygen monitoring device converts the third feedback optical signal into a third digital signal, and converts the fourth feedback optical signal into a fourth digital signal.

After being reflected by the human body, the third detection light signal and the fourth detection light signal pass through the first filter of the blood oxygen monitoring device to filter out the ambient light, and are received by the miniature photoelectric receiving tube of the blood oxygen monitoring device. Wherein, the third feedback optical signal is the optical signal of the third detection optical signal reflected by the human body, and the fourth feedback optical signal is the optical signal of the fourth detection optical signal reflected by the human body.

Subsequently, the second filter and amplifier of the blood oxygen monitoring device filter and amplify the third feedback optical signal and the fourth feedback optical signal, and convert them into third digital signals and fourth digital signals through an analog-to-digital converter.

S109. The blood oxygen monitoring device generates a second monitoring result according to the third digital signal and/or the fourth digital signal.

Wherein, the second monitoring result is used to indicate the blood oxygen content of the human body.

After obtaining the third digital signal and the fourth digital signal, the processor of the blood oxygen monitoring device generates a second monitoring result according to the third digital signal and/or the fourth digital signal. As a result, the measurement accuracy of the blood oxygen monitoring device is improved.

S110. If the first monitoring result is less than or equal to the second preset value, the blood oxygen monitoring device generates alarm information and sends it to the user equipment, so that the user equipment emits an alarm sound according to the alarm information.

If the first monitoring result is less than or equal to the second preset value, it means that the current blood oxygen content of the human body is lower than the healthy value, and life may be in danger in this state, so the processor of the blood oxygen monitoring device generates an alarm message and sends to the user equipment, so that the user equipment sends out an alarm sound according to the alarm information. Wherein, the alarm sound may be any sound that can attract the user's attention, such as ringtones, vibrations, and voice prompts.

S111. If the first monitoring result is greater than or equal to the first preset value, the blood oxygen monitoring device maintains the current working state.

If the first monitoring result is greater than or equal to the first preset value, it means that the current blood oxygen content of the human body is at a normal level, and in this state, the blood oxygen monitoring device only needs to maintain the current working state.
