The blood oxygen concentration compensation method 200 executes step S230, continuously detects a plurality of acceleration signals by the gravity sensor 120, and then executes step S240, and then the processor 130 converts the acceleration signals into a plurality of corresponding momentums. In one embodiment, the gravity sensor 120 detects the acceleration of three axes (Pitch, Yaw, Roll), and the processor 130 is used to select the acceleration value of the three axes detected by the gravity sensor 120 with the largest value.

In another embodiment, the processor 130 can also quantify the acceleration value to a range of 0-100 as the momentum after taking the average or maximum value of the accelerations of the three axes, but the present disclosure is not limited thereto.

《公式1》The blood oxygen concentration compensation method 200 executes step S250, and the processor 130 calculates the momentum weight corresponding to each momentum respectively. In one embodiment, the processor 130 first converts each momentum into a corresponding momentum index value, and the method of converting the momentum into a momentum index value can be calculated from "Formula 1". The nth momentum index value is the parameter Wai(n), and the nth momentum is the parameter activity value(n). For example, the currently received momentum is 0, and the momentum index value is 100 at this time.

"Formula 1"

As mentioned above, the momentum represents the vibration level of the user's finger or wrist detected by the gravity sensor 120 , and the larger the acceleration value is, the stronger the vibration level of the user's finger or wrist is. The momentum index value indicates the degree of reverse vibration.

Conversely, the lower the momentum index value, the lower the weighted value, and the lower the reference value for the blood oxygen concentration.

《公式2》Next, the processor 130 calculates the momentum weight by dividing the nth momentum index value to the y power by the sum of the m momentum index values to the y power. Momentum weights can be calculated from Equation 2. The n-th momentum weight is the parameter Wa(n), and m data is sampled continuously. Here, m is assumed to be 12, and y is assumed to be 2. The present disclosure is not limited to this.

"Formula 2"

In accordance with the above, for example, please refer to the example of "Table 1". "Table 1" shows parameters such as blood oxygen concentration value, momentum, momentum index value and momentum weight. For example, the currently detected data is the #1 data shown in "Table 1", the blood oxygen concentration value is 95, the momentum is 0, the momentum index value is 100, and the calculated momentum weight is 1.4101. pen count blood oxygen concentration momentum Momentum index value Momentum weight #1 95 0 100 1.4101 #2 95 0 100 1.4101 #3 95 20 80 1.12808 #4 90 20 80 1.12808 #5 88 30 70 0.98707 #6 70 50 50 0.70505 #7 70 40 60 0.84606 #8 88 30 70 0.98707 #9 90 20 80 1.12808 #10 95 0 100 1.4101 #11 95 0 100 1.4101 #12 95 0 100 1.4101 "Table 1"

In one embodiment, the processor 130 first calculates a time parameter corresponding to each blood oxygen concentration value, and the time parameter can be calculated from "Formula 3". The number of samples is parameter m, the time index value is Wti(n), and k is the weakening parameter of time. Here, m is assumed to be 12, k is assumed to be 2, the first detected data is n=1 as shown in "Table 1", so the time index value of the first data is 23, and the present disclosure is not limited to this .

"Formula 3"

《公式4》Next, the processor 130 calculates the nth time weight by dividing the nth time parameter by the sum of the time parameters. The nth time weight can be calculated by "Formula 4". The n-th time weight is Wt(n), and m data is sampled consecutively. Following the previous embodiment, m is assumed to be 12, but the present disclosure is not limited to this.

"Formula 4"

Based on the above, for example, please refer to the example of "Table 2", and "Table 2" displays parameters such as blood oxygen concentration value, momentum weight, time index value, and time weight. For example, the currently detected data is the #1 data shown in "Table 2", the blood oxygen concentration value is 95, and the calculated time weight is 1.3142. It is worth noting that the time weight of the earlier sampling results will be lower and lower as the time series distance from the current time is farther. Therefore, temporal weighting can weaken earlier sampling results. pen count blood oxygen concentration Momentum weight time index value time weight #1 95 1.4101 twenty three 1.3142 #2 95 1.4101 twenty two 1.2571 #3 95 1.12808 twenty one 1.2 #4 90 1.12808 20 1.1428 #5 88 0.98707 19 1.0857 #6 70 0.70505 18 1.0285 #7 70 0.84606 17 0.9714 #8 88 0.98707 16 0.9142 #9 90 1.12808 15 0.8571 #10 95 1.4101 14 0.8 #11 95 1.4101 13 0.7428 #12 95 1.4101 12 0.6857 "Table 2"

《公式5》

《公式6》The blood oxygen concentration compensation method 200 executes step S270, and the processor 130 calculates a corresponding final weight according to the momentum weight and the time weight, and generates a compensated blood oxygen concentration value according to the final weight. In one embodiment, the processor 130 multiplies the momentum weight and the time weight to obtain the nth final weight W(n), and the final weight can be calculated according to "Equation 5". Next, the processor 130 multiplies and sums the nth final weight W(n) by the nth blood oxygen concentration value SpO2(n) to calculate the current compensated blood oxygen concentration value ASpO2. The compensated current blood oxygen concentration The concentration value can be calculated from "Formula 6".

"Formula 5"

"Formula 6"

Based on the above, for example, please refer to the example of "Table 3". "Table 3" shows parameters such as blood oxygen concentration value, momentum weight, time weight, final weight, and the result of multiplying blood oxygen concentration value and final weight. For example, the currently detected data is the #1 data shown in "Table 3", the blood oxygen concentration value is 95, the momentum weight is 1.4101, the time weight is 1.3142, the final weight is 0.13333, the blood oxygen concentration value is the same as The final weight multiplication result is 12.66636. Finally, the blood oxygen concentration value of #1~#12 data is added up with the final weight multiplication result, and the corrected blood oxygen concentration value can be calculated as 90. After the above calculation, the noise caused by the shaking of the user's finger or wrist can be suppressed, and the data that is close to the current time point can be emphatically considered. pen count blood oxygen concentration Momentum weight time weight final weight Blood oxygen concentration value × final weight #1 95 1.4101 1.3142 0.13333 12.66636 #2 95 1.4101 1.2571 0.127537 12.11602 #3 95 1.12808 1.2 0.097395 9.252552 #4 90 1.12808 1.1428 0.092753 8.34775 #5 88 0.98707 1.0857 0.077104 6.785116 #6 70 0.70505 1.0285 0.052172 3.65207 #7 70 0.84606 0.9714 0.059131 4.139178 #8 88 0.98707 0.9142 0.064924 5.713321 #9 90 1.12808 0.8571 0.069565 6.260812 #10 95 1.4101 0.8 0.081163 7.71046 #11 95 1.4101 0.7428 0.07536 7.159162 #12 95 1.4101 0.6857 0.069567 6.608828 "table 3"

As mentioned above, after the processor 130 calculates the compensated blood oxygen concentration value, it transmits the compensated blood oxygen concentration value to the display 150 for display. In one embodiment, the processor 130 is further configured to determine whether the degree of vibration of the user's finger or wrist is too large, so as to affect the accuracy of the blood oxygen detector 110 in detecting the blood oxygen concentration. Therefore, the processor 130 is used to determine whether the momentum is greater than or equal to the first threshold value, and if the activity value is greater than or equal to the first threshold value, the processor 130 is used to reset the blood oxygen concentration value and send a warning signal to the display 150. The display 150 is used for displaying a warning image.

Based on the above, for example, it is assumed here that the first threshold value is 80, the blood oxygen concentration value of the latest data is 80, the momentum is 80, and the momentum of the latest data is equal to the first threshold value, so the processor 130 will clear the storage The #1 data to #12 data in the memory unit 160 and the momentum data (momentum, momentum index value and momentum weight) of the latest data are not considered, and the detection result of the blood oxygen detector 110 is directly displayed on the display 150 (the blood oxygen concentration value is 80) and a warning screen to remind the user that the current excessive momentum has affected the detection result of the blood oxygen detector 110 .

It is worth noting that when the acceleration signal detected by the gravity sensor 120 returns to normal (the momentum is less than the first threshold value), the memory unit 160 will record the acceleration signal again. When the accumulation reaches m strokes (here, it is assumed to be 12 strokes) When the data is obtained, the processor 130 recalculates the momentum data (momentum, the momentum index value and the momentum weight) and the time weight, and displays the compensated blood oxygen concentration value through the display 150 .

As mentioned above, the processor 130 is further configured to determine whether the vibration level of the user's finger or wrist is within the allowable range. Therefore, the processor 130 is used to determine whether the momentum is greater than the second threshold value and less than the first threshold value, and if the activity value is between the first threshold value and the second threshold value, the processor 130 is used to send a reminder signal To the display 150 , the display 150 is used for displaying a reminder screen to remind the user that the current vibration level of the finger or wrist may affect the accuracy of the blood oxygen detector 110 .

Based on the above, when the momentum is less than the first threshold, the processor 130 will delete the oldest piece of data (#12 pieces of data shown in Tables 1 to 3), and add the latest piece of data to the memory unit 160 as the current piece of data 's #1 profile. For example, it is assumed here that the second threshold value is 20, the blood oxygen concentration value of the latest data is 90, the momentum is 40, and the momentum of the latest data is greater than the second threshold value (20) and less than the first threshold value (80 ). The processor 130 recalculates the momentum data (momentum, momentum index value, and momentum weight) of the #2 data to #12 data according to the momentum of the latest data, and displays a reminder on the display 150 that the compensation is in progress.

In one embodiment, the processor 130 is further configured to determine whether there is too much noise caused by vibration in the m pieces of data, resulting in an increasing error when the processor calculates the blood oxygen concentration value. Therefore, the processor 130 is further configured to determine whether the sum of the momentum index values (Wai) is greater than the third threshold value, and if the sum of the momentum index values (Wai) is smaller than the third threshold value, the processor 130 is configured to reset the blood oxygen concentration value .

Based on the above, the processor 130 is used to calculate whether the sum of the momentum index values of the #1 data to the #12 data is less than the third threshold value. If it is less than the third threshold value, the processor 130 will clear the data stored in the memory unit 160. #1 data~#12 data, avoid the final weight inaccurate due to the accumulation of too many low-weight data in the memory unit. At the same time, the processor 130 will directly display the detection result of the blood oxygen detector 110 and the warning screen through the display 150 to remind the user that there is continuous vibration and shaking, which causes the detection result of the blood oxygen detector 110 to be disturbed continuously. affect accuracy.

In one embodiment, before calculating the blood oxygen concentration value, the processor 130 is further configured to determine whether the user's finger or wrist is detected. In the embodiment shown in FIG. 3A, the blood oxygen detector 110 has transmitters 111a and 111b and a light sensor 112. The transmitters 111a and 111b are used for emitting the first ray and the second ray respectively, and the light sensing The device 112 is used for detecting the first ray and the second ray. The processor 130 is configured to compare whether the difference between the amplitude of the first ray and the amplitude of the second ray is greater than a fourth threshold value. If the difference value is greater than the fourth threshold value, it means that the currently detected object is not an object with a pulse.

Please refer to FIG. 4A and FIG. 4B.

Based on the above, as shown in FIG. 4B, the difference between the amplitude S1A of the first ray and the amplitude S2A of the second ray is smaller than the fourth threshold value, and the signal S1 of the first ray and the signal S2 of the second ray have similar periods, It indicates that the object penetrated by the first ray and the second ray should be an object with a pulse, and the processor 130 may further calculate the compensated blood oxygen concentration value. It is worth noting that the processor 130 can control the blood oxygen detector 110 to detect whether there is a user's finger or wrist approaching at regular intervals (eg, 2-5 seconds or 5-10 seconds).

Next, please refer to FIG. 5 , which is a schematic diagram of a blood oxygen monitoring system 500 according to some embodiments of the present application.
