Blood oxygen saturation If you want to take a measurement, insert your right finger into your left hand. If you want to ask a question, press the switch on your foot. "

First, the electrocardiogram measurement process will be described with reference to FIG. The CPU 24 initializes the count value m in step S1, and in step S3, the electrocardiographic signal (potential).
Is sampled to calculate the potential difference V (m) between both electrodes. Subsequently, 1 is added to the count value m in step S5, and it is determined in step S7 whether the count value m has reached 600, that is, whether 600 pieces of data of the potential difference V (m) have been collected. If NO in step S7, the process returns to step S3 and the calculation of the potential difference V (m) is repeated. As a result, the sampling process in step S3 is performed 600 times, for example, every 0.008 seconds. Step S
If YES is determined in step 7, the process proceeds to step S9, and noise having the potential difference V (m) is removed by filtering.
In step S11, the potential difference V (m) from which noise has been removed
The peak value and the average value of are calculated, and the threshold value is calculated in step S13. The threshold value is, for example, 1/2 of the sum of the peak value and the average value. In step S15, the peak timing is detected by comparing the potential difference V (m) from which the noise is removed with the threshold value. When the peak timing is detected, the peak timing interval is calculated in step S17, the average value p and the variance q thereof are calculated, and whether the average value p and the variance q are within a predetermined range respectively in step S19. to decide.

When the patient is not trying to measure the electrocardiogram, that is, when the fingers are not touching the electrocardiographic electrodes 40a and 40b, only noise is detected and the R wave of the electrocardiographic waveform is not detected. The average value p and the variance q of the peak interval are not within a predetermined range, that is, within the range of the average value and the variance of the R wave interval. Therefore, step S1
If NO in step 9, the process returns to step S1 and the processes of steps S1 to S19 are repeated. That is, continue to monitor whether the patient is trying to measure the electrocardiogram. on the other hand,
If YES in step S19, since the patient is trying to measure electrocardiography, the process proceeds to step S21, and measurement processing (monitoring) of another sensor is interrupted. Then, the actual electrocardiogram measurement is processed in the processing of step S23 and subsequent steps.
Before proceeding to step S23, a voice message such as "measurement of an electrocardiogram" is issued, and the patient is instructed to continue to touch the electrocardiographic electrodes 40a and 40b because the measurement mode has been entered. May be.

Subsequently, the CPU 24 initializes the count value n in step S23, and samples the electrocardiographic voltage in step S25 to calculate the potential difference V (n) between both electrodes. Then, 1 is added to the count value n in step S27, and whether the count value n becomes 4000, for example, in step S7, that is, the data of the potential difference V (n) is 400.
Judge whether 0 pieces have been collected. If NO in step S29, the process returns to step S25 to repeat the calculation of the potential difference V (n). As a result, the sampling process in step S25 is performed 4000 times, for example, every 0.008 seconds.
If YES is determined in the step S29, a step S31 is performed.
Go to.

In step S31, analysis of measurement data is processed. That is, the measured electrocardiogram data is analyzed by, for example, a known analysis method or the like to calculate, for example, the heart rate or the possibility of arrhythmia. Then, step S33
Then, the voice message such as the measurement result and the advice is issued. As the voice message, for example, "Heart rate was ...", "There is a risk of arrhythmia, please consult a doctor." After that, the monitoring processing of other sensors is restarted and the electrocardiogram measurement processing is ended.

Next, the body temperature measuring process will be described with reference to FIG. In step S35, the CPU 24 samples the output signal (temperature signal) from the temperature sensor 42 to calculate the temperature T0, and in step S37, determines whether the temperature T0 exceeds 32.0 degrees, for example. When the patient is trying to measure body temperature, the temperature T0 is 32.0
If the answer is NO in step S37, the process returns to step S35 to repeat the calculation of the temperature T0. The process in step S35 is a process of monitoring whether the patient is trying to measure the body temperature, and is performed, for example, every 0.1 seconds. On the other hand, YES in step S37.
If so, the process proceeds to step S39. Note that step S39
Before proceeding to step 1, a voice message such as "Measuring body temperature" may be issued to notify the patient that the measurement mode has been entered.

In step S39, the temperature T1 is set to T0.
And count values m and n are initialized,
In step S41, the measurement processing (monitoring) of other sensors is interrupted. Then, in step S43, the output signal from the temperature sensor 42 is sampled to calculate the temperature T2, and in step S45, it is determined whether the latest temperature T2 is lower than the previous temperature T1, that is, whether the temperature has dropped. To do. Since the temperature should not drop when the body temperature is properly measured, if NO in step S45, the count value m is initialized in step S47, and step S4 is executed.
At 9, the amount of change in temperature is judged. On the other hand, step S
If YES in 45, in step S51 the count value m
Is incremented by 1 and it is determined in step S53 whether the count value m exceeds 10, for example. In other words, the temperature drop is 1
If it continues more than 0 times, it is determined as YES, and it is determined that the temperature measurement is not appropriate, and the measurement of the body temperature is stopped in step S55. If NO in step S53, the process proceeds to step S49.

In step S49, it is determined whether the absolute value of the difference between the latest temperature T2 and the previous temperature T1 is smaller than 0.05, for example. That is, if the temperature change is relatively large, NO is determined in step S49, the count value n is initialized in step S57, and step S5 is performed.
The temperature T2 is replaced with the temperature T1 in 9 and the process returns to step S43 to repeat the sampling of the temperature signal. On the other hand, if almost no temperature change has occurred, then in step S49 Y
It is determined to be ES, 1 is added to the count value n in step S61, and the process proceeds to step S63.

In step S63, it is determined whether the count value n exceeds 100, for example. NO in step S63
If so, the process proceeds to step S65 to determine whether or not there is a cancel operation, and if there is a cancel operation, the process proceeds to step S55 to stop the measurement. If there is no cancel operation, the process returns from step S59 to step S43 to perform temperature sampling. repeat.
On the other hand, if YES in step S63, the state in which the temperature change hardly occurs is observed more than 100 times, so that the temperature signal T2 is almost the same as the actual body temperature, the sampling of the temperature signal is ended, and the step S67 is performed. Go to.

Then, in step S67, a voice message such as the measurement result (temperature T2) and advice is issued. As the voice message, for example, "body temperature is ... degree ... minutes, please consult a doctor" is issued. When the process of step S67 or S55 is completed, the process proceeds to step S69, the monitoring process of other sensors is restarted, and the body temperature measuring process is paused for one minute, for example, in step S71. Then, the body temperature measurement process ends. The body temperature may be measured, for example, by a measurement formula for measuring for 5 minutes.

Next, the SpO2 measurement process will be described with reference to FIG. The CPU 24 activates the pulse generator in step S73, and in subsequent step S75, receives the light emitted from the first light emitting unit 54 and the second light emitting unit 56, samples the optical signal output from the light receiving unit 62, and The transmitted light intensity I1 when the first light emitting unit 54 emits light and the transmitted light intensity I2 when the second light emitting unit 56 emits light are calculated.
Then, in step S77, the transmitted light intensities I1 and I2 are
Is above a predetermined value.

When the patient is not trying to measure SpO2, the light emitted from the first light emitting portion 54 and the second light emitting portion 56 is directly received by the light receiving portion 62 without passing through the finger.
Therefore, the transmitted light intensities I1 and I2 have a value larger than a predetermined value. Therefore, step S77
If YES, the process returns to step S75 to repeat the sampling of the optical signal to continue monitoring whether the patient is going to measure SpO2. On the other hand, step S77
If NO in step S79, the measurement processing (monitoring) of the other sensors is interrupted in step S79, and the actual SpO2 measurement is processed in the processing of step S81 and subsequent steps. Note that step S8
Before proceeding to step 1, a voice message such as “Measuring SpO2” may be issued to notify the patient that the measurement mode has been entered.

In step S81, the optical signal is sampled and the transmitted light intensities I1 and I2 are calculated. Succeedingly, in a step S83, it is determined whether or not a predetermined measurement time has elapsed. If NO in step S83, step S81
If the determination is YES, the average values I10 and I20 of the transmitted light intensities I1 and I2 are calculated in step S85, and SpO2 is calculated in accordance with the equation of Formula 1 in step S87. That is, the transmitted light intensity ratio I10
SpO2 is calculated based on / I20 and the constants A and B.

[0044]

## EQU1 ## SpO2 = A + B.times.I10 / I20 Then, in step S89, a voice message such as a result and advice is issued. As the voice message, for example, "SpO2 was ... Please see a doctor" is issued. After that, the monitoring processing of other sensors is restarted and the SpO2 measurement processing is ended.

Next, the inquiry processing will be described with reference to FIG. In step S91, the CPU 24 determines whether or not the foot switch (the inquiry answer switch 34a or 34b) has been pressed. If NO in step S91, the determination in step S91 is repeated to continue monitoring whether or not the patient is going to have an inquiry, and if YES, the process proceeds to step S93 to start the inquiry.

In step S93, voice guidance is issued regarding the inquiry operation. As the voice guidance, for example, "If the left foot switch is pressed, the physical condition check inquiry will be performed, and if the right foot switch is pressed, the lifestyle check inquiry will be started." Succeedingly, in a step S95, it is determined whether or not the left foot switch (the inquiry answer switch 34a) is pressed, and if YES, the inquiry data for physical condition check is read from the database 76 in a step S97. On the other hand, N in step S95
If it is O, it is determined in step S99 whether or not the right foot switch (question answer switch 34b) has been pressed. If YES, the lifestyle check inquiry data is read from the database 76 in step S101. Note that step S9
If NO in step 9, the process returns to step S93, and voice guidance is issued again regarding the inquiry operation.

Here, the inquiry data for checking the physical condition and lifestyle includes each of 10 questions as shown in FIGS. 10 (A) and 10 (B). In addition, a cautionary answer that the physical condition and lifestyle are not good is set for each question, and further, a result of each inquiry and advice according to the number of cautionary answers are set.

When the process of step S97 or S101 is completed, the process proceeds to step S103, for example, "The inquiry will be started. To answer" Yes "to the question, press the left foot switch, and to answer" No ", press the right foot switch. Please give a voice guidance such as "Please". In the following step S105, step S97 or step S101.
Speak each question content (question) from the physical condition or lifestyle inquiry data read in step S107, and in step S107,
Determine if there was a switch operation for the question. If NO in step S107, the determination in step S107 is repeated, waiting for the patient's reply, and if YES, step S107
Go to 109. When the operation is performed in step S107, the answer (Yes / No) selected by the patient may be spoken by voice so that the patient can confirm the switch operation.

Then, in step S109, it is determined whether or not the patient's answer (yes / no) is a caution request answer, and if it is a caution request answer, in step S111 the number of caution request answers is accumulated. Then, the process proceeds to step S113, and if the response does not indicate a caution, the process proceeds directly to step S113.

Succeedingly, in a step S113, it is determined whether or not all the questions are completed, and if NO, the step S10 is performed.
Go back to 5 and continue asking questions. On the other hand, in step S113, Y
If it is ES, in step S115, the result of the inquiry according to the number of attention-required answers, advice, etc. are uttered as a voice message. Then, the monitoring processing of the other sensors is restarted and the inquiry processing is ended.
