DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a health information terminal device for receiving physiological information from a physiological information recording device for detecting and recording physiological information of a subject and remotely performing information processing such as communication with a doctor or the like. .

[0002]

2. Description of the Related Art In recent years, from the importance of home health care,
Various systems have been proposed in which a subject transmits physiological information measured at home to a remote doctor via a communication line, and the doctor diagnoses the result. As a problem in the system connected to these communication lines, when the subject is measuring the physiological information while touching the electrodes of the device, insulation must be taken into consideration so that, for example, even if there is a lightning strike, the subject is not in danger. This is particularly important for measurements that require electrodes that come into contact with the subject's body, such as electrocardiograms.

[0003] For this purpose, for example, Japanese Patent Laid-Open Publication No.
There is an apparatus described in Japanese Patent Publication No. 3 and described with reference to FIG. FIG. 9 is a block diagram of an electrocardiogram recording apparatus 1 for explaining a conventional example, and an electrocardiogram detecting section 2 for detecting an electrocardiogram from a human body.

An electrocardiogram sending push button switch 5 pressed by the like, an electrocardiogram sending section 6 for frequency-modulating the signal from the electrocardiogram recording section 3 as an audio signal, and an amplifier 7 for amplifying the signal from the electrocardiogram sending section 6.
And a speaker 8 for transmitting the signal amplified by the amplifier 7 as an acoustic signal, and an arithmetic control unit 9 including a microprocessor programmed in advance to control the entire electrocardiogram recording apparatus 1.

[0004] When the home patient touches the electrocardiogram detecting section 2 on the chest and presses the electrocardiogram recording push button switch 4, the operation control section 9 is activated.
Processes the signal from the electrocardiogram detecting section 2 and processes the signal from the electrocardiogram recording section 3
Is supplied to the ECG recording unit 3 for a predetermined time.
Will be recorded.

[0005] Next, the home patient uses the telephone to send a predetermined dial and start transmission of the electrocardiogram. At this time, the home patient presses the speaker 8 of the electrocardiogram recording device 1 against the microphone of the telephone and presses the electrocardiogram sending push button switch 5. Here, the arithmetic and control unit 9 sends the ECG data recorded in the ECG recording unit 3 to the ECG sending unit 6, and the ECG sending unit 6 converts the ECG data into an ECG signal frequency-modulated based on a predetermined function. This ECG signal is
And is transmitted from the speaker 8 as an acoustic signal.
A remote receiver such as a doctor receives the acoustic signal by telephone and reproduces an electrocardiogram.

In such a system, the electrocardiogram recording device 1
However, if the power supply is not a commercial power supply, such as a battery power supply, for example, when the electrocardiogram is detected, the power supply line and the telephone line are insulated, and the safety of the patient is ensured. The electrocardiogram can then be transmitted remotely over a telephone line.

[0007]

In order to frequency-modulate the ECG data and transmit the data as an acoustic signal, the higher the frequency, the higher the resolution of the data in a short time. However, there is a problem that the frequency cannot be set too high when shared for transmitting electrocardiogram data through a communication line that transmits human voice.

That is, in order to transmit the electrocardiogram data accurately, it is necessary to pass through a filter that passes only near the frequency band to be transmitted in order to reduce the influence of noise or the like.
However, in order to transmit human voice clearly even after passing through the filter, the electrocardiogram data must have a frequency close to the frequency band of general human voice.

The present invention solves the above-mentioned conventional problems, and transmits human voice and physiological information such as an electrocardiogram remotely via a communication line. The present invention conveys human voice clearly and transmits physiological information at high speed. The purpose is to transmit accurately and with high resolution.

[0010]

In order to solve the above-mentioned conventional problems, a health information terminal device according to the present invention provides a physiological information processing unit or a voice processing unit that switches a path of an electric signal output from a receiving unit by a subject's switching operation.

A physiological information filter that removes noise, the audio processing unit has an audio filter that eliminates noise of the electric signal from the receiving unit, and the physiological information filter and the audio filter have different frequency characteristics. It is configured.

Thus, when the subject has a conversation with a remote person via the communication line, the electric signal from the receiving unit is switched to the voice processing unit, and the voice processing unit has a voice filter having a frequency characteristic suitable for human voice. Can be transmitted clearly and clearly with the noise component removed. When the subject transmits the physiological information remotely via a communication line, the signal from the receiving unit is switched to the physiological information processing unit, and the physiological information processing unit has a physiological characteristic having a frequency characteristic suitable for the sound emitted from the physiological information recording device. Because of the presence of the information filter, the electric signal from the receiving unit can be accurately and remotely transmitted without being affected by noise. Since the voice filter and the physiological information filter are provided separately, the frequency characteristics of the filters can be designed to suit each.By designing the physiological information filter at high frequency, physiological information can be accurately and remotely separated at high speed with high resolution. It becomes possible to transmit.

The physiological information processing unit 15 includes a physiological information filter 19, and the audio processing unit 16 includes an audio filter 20. The physiological information filter 19 and the audio filter 20 are electronic circuits of a general band-pass filter that amplify frequencies within a predetermined range as significant signals and do not amplify or attenuate frequencies outside the range as noise.

Also, human voices can be conveyed clearly.

(Embodiment 2) FIG. 4 is a block diagram illustrating the configuration of an information communication apparatus 12 of a health information terminal apparatus according to Embodiment 2 of the present invention. 4, components having the same functions as those in the first embodiment are denoted by the same reference numerals. As in the first embodiment, when a subject or the like transmits an electrocardiogram measured by the physiological information recording device 1 to a remote doctor or the like to the remote doctor or the like, the switch 18 is operated and the signal of the microphone 14 is transmitted to the physiological information processing unit 15. Output.

In the second embodiment, the physiological information processing section 15 processes the electrocardiogram signal received from the physiological information recording apparatus 1 to reproduce and display the electrocardiogram, and determines whether or not to transmit data remotely via the line communication section 17. This is selected by the operation of the subject or the like.

The physiological information processing section 15 detects the physiological information filter 19 having the same configuration as that of the first embodiment and calculates the frequency of the acoustic signal from the microphone 14 via the physiological information filter 19 to thereby detect the physiological information. A physiological information reproducing unit 21 for reproducing electrocardiogram data, and a speaker 8 of the physiological information recording device 1 based on an electric signal generated by the physiological information filter 19.
, A start signal transmitting section 22 for detecting that an acoustic signal has begun to be emitted and transmitting a signal to the physiological information reproducing section 21, and a display section 2 for displaying electrocardiogram data reproduced by the physiological information reproducing section 21.
3. The configuration includes a selection operation unit 24 for the subject or the like to check the electrocardiogram on the display unit 23 and select whether to transmit the electrocardiogram remotely. In the case of remote transmission, the electrocardiogram data reproduced by the physiological information reproducing unit 21 is Is transmitted to a remote doctor or the like via the communication line 13.

The start signal transmitting section 22 sends a start signal to the physiological information reproducing section 21 when it detects that an acoustic signal has started to be emitted from the speaker 8 of the physiological information recording apparatus 1 based on the electric signal generated by the physiological information filter 19. , An amplitude determination unit 25, a frequency determination unit 26, and a timer 27.
It is a configuration including. The physiological information recording device 1 has a predetermined frequency of an emitted acoustic signal, and can emit only a frequency within a predetermined range. With this configuration, if the amplitude is determined to be greater than or equal to a predetermined value by the amplitude determining unit 25, the frequency is determined to be within a predetermined range by the frequency determining unit 26, and if the state continues for a predetermined time (eg, 1 second) by the timer 27, the physiological information recording apparatus It is possible to detect that an acoustic signal has begun to be emitted from one speaker 8.

The physiological information reproducing section 21 comprises a recording section 28 and a frequency calculating section 29. The recording unit 28 has an AD conversion function, performs AD conversion on the signal from the physiological information filter 19 at a predetermined sampling cycle, and stores the voltage level as a digital value.

The frequency calculating section 29 includes a peak extracting section 30,
It comprises a counter 31, a reciprocal operation unit 32, and a storage unit 33.
The peak extracting unit 30 sequentially examines the digital value of the time-series voltage level stored in the recording unit 28, examines whether it has increased or decreased as compared with the previous value, and switches from increasing to decreasing. Extract as peak.

The counter 31 counts the number of peaks at which the peak extraction unit 30 switches from increasing to decreasing a predetermined number of times (for example, 10 times).
During the extraction, the number of times of sampling in the recording unit 28 is counted. The meaning of the count value is a time required for generating a predetermined number of peaks by multiplying the count value by the sampling period in the recording unit 28. That is, the count value of the counter 31 is a value proportional to the time required for the occurrence of a predetermined number of peaks.

Further, the reciprocal calculating section 32 calculates the reciprocal of the count value in the counter 31. Here, since the reciprocal of a value proportional to the time required to generate a predetermined number of peaks is calculated, the calculation result is a value proportional to the frequency. Therefore, the frequency is obtained by multiplying the reciprocal by a predetermined constant. The frequency calculated by the reciprocal calculator 32 in this manner is the frequency of the acoustic signal received by the microphone 14, that is, the frequency of the acoustic signal emitted from the physiological information recording device 1.

The storage unit 33 converts the original electrocardiogram data into digital data by performing a reverse conversion of the conversion performed by the frequency modulation unit 6 of the physiological information recording device 1 from the frequency data calculated by the reciprocal calculation unit 32. Store as a value. The frequency calculation unit 29 repeats the above operation,
The electrocardiogram data recorded by the physiological information recording device 1 can be stored in the storage unit 33 in chronological order.

The display section 23 displays the time-series electrocardiogram data stored in the storage section 33 as a graph. The patient can check the electrocardiogram by the graph displayed on the display unit 23. Here, if the patient confirms that the electrocardiogram has been correctly recorded, the patient instructs to remotely transmit the electrocardiogram data by operating the selection operation unit 24. If the electrocardiogram could not be recorded correctly due to improper use of the physiological information recording device 1 or the like, it can be understood by a graph display, and the transmission to the remote is performed without operating the selection operation unit 24. Instead, the electrocardiogram may be recorded again by the physiological information recording device 1.

Upon receiving the transmission instruction from the selection operation unit 24, the line communication unit 17 transmits the time-series electrocardiogram data stored in the storage unit 33 to a remote doctor or the like via the communication line 13. Since the line communication 17 transmits the digital value of the storage unit 33, the electrocardiogram data transmitted to a remote doctor or the like is the same as the electrocardiogram data confirmed by the patient on the display unit 23.

FIG. 5 shows an example of a specific electric circuit diagram of the start signal transmitting section 22. The start signal transmitting section 22 receives the output signal of the physiological information filter 19, and comprises an operational amplifier 34 and three resistors 35, 36, 37 constituting the amplitude determining section 25.
And a microcomputer 38 that performs the functions of the frequency determination unit 26 and the timer 27.

Since the amplitude judging section 25 is configured as a comparison circuit having a hysteresis function, the resistors 35, 3
An arbitrary amplitude can be set as a threshold value by selecting the resistance values of 6, 37. With this configuration, if the amplitude of the output signal of the physiological information filter 19 is equal to or larger than a predetermined value, the output signal of the operational amplifier 34 becomes a rectangular wave.

The microcomputer 38 receives the output signal of the operational amplifier 34 as an input and performs the functions of the frequency determination unit 26 and the timer 27. Then, when the frequency in the predetermined range continues for a predetermined time, a start signal is transmitted to the recording unit 28. The microcomputer 38 has a counter function,
That terminal is used as an input terminal.

FIG. 6 is a flowchart showing the program of the microcomputer 38. The program shown in FIG. 6 is an example of transmitting a start signal when a frequency of 2.5 to 3.5 kHz as a predetermined range continues for one second. For this reason, the start signal is transmitted when the pulse input frequency P for 0.1 second is 250 to 350 times for ten consecutive times.

First, a counter N for counting the number of consecutive times is reset to 0 (S-1). Further, a counter P for counting the number of pulses for 0.1 second is reset to 0 (S-2). Then, it waits for the elapse of 0.1 second (S-3). The microcomputer 38 having the counter function automatically counts the number of pulses during standby. After 0.1 seconds,
It is checked whether the value of the counter P is in the range of 250 to 350 (S-4).

If it is not in the range of 250 to 350, it is determined that there is no acoustic signal from the physiological information recording device 1, and the process returns to S-1 where the counter N for counting the number of continuous times is reset to 0. If the number is within the range of 250 to 350, the number of consecutive times N is counted (S-5). As a result, it is confirmed whether N becomes 10 or more (S-6). If N is less than 10, the process returns to S-2 and repeats from setting the pulse number counter P to 0. If N is 10 or more, the start signal is transmitted assuming that the number of times is 10 (S-7). With the above program, the start signal can be transmitted after confirming that the acoustic signal in the range of 2.5 to 3.5 kHz has been received continuously for one second. If the microcomputer 38 has an AD conversion function, the function of the amplitude determination unit 25 may be provided by a program.

Next, the operation of the physiological information reproducing section 21 will be described with reference to FIGS. For example, 5
The input signal from the physiological information filter 19 is AD-converted by 8 bits at a sampling period of 0 μsec (sampling frequency of 20 kHz) and recorded. In FIG. 7, when the horizontal axis represents the elapsed time and the vertical axis represents the recorded digital value, X
0, X1, X2,..., Xi-1, Xi,.

The peak extracting section 30 compares the digital value of the time series with the value of the previous time, and extracts the point where the value has changed from increasing to decreasing. That is, since X1 increases from X0 but X2 decreases from X1, X2 is extracted as a peak. Next, Xi is extracted as a peak in FIG.

The counter 31 counts the number of times of sampling in the recording unit 28 while the peak is extracted a predetermined number of times (for example, 10 times). Assuming that the number of samplings is m, the time required for 10 peaks is m * 50 μse
c. The frequency is obtained by multiplying the reciprocal by 10 times.

FIG. 8 is a flowchart of a program in the case where the above-described operation is realized by using the microcomputer in the physiological information reproducing unit 21. First, as an initial process, the counter PC for peak extraction and the counter SC for the number of times of sampling are set to 0, and the increase / decrease flag F is set to 0 meaning increase (S-11). Then, the following loop is repeated to check n digital values of the AD conversion sampling recorded in the recording unit 28 (S-12).

First, the counter of the number of times of sampling is counted (S-13), and it is compared whether or not the sampling digital value Xi is smaller than the previous sampling digital value Xi-1 (S-14). If not smaller, the flag F is set to 0, and the process returns to S-13 at the beginning of the loop (S-1).
5). If the result of the comparison in S-14 is smaller than the previous sampling digital value, the flag F is checked (S-16). Then, if F is not 0, since it has been decreased last time and is not a peak, the process returns to S-13 at the beginning of the loop.

In step S-16, if F is 0, the value has increased the previous time and has now decreased, and can be extracted as a peak. In this case, the flag F is set to 1 meaning decrease (S-17), and the peak counter PC is counted (S-18). Then, the PC is extracted a predetermined number of times 1
It is compared with 0 (S-19), and if it is less than 10, the process returns to S-13 at the beginning of the loop.

If the PC is 10 or more in S-19, the frequency f is calculated here (S-20). In the calculation of the frequency, the value obtained by multiplying the sampling frequency counter SC by the sampling period is the time required for 10 peaks. Therefore, the frequency can be calculated by calculating the reciprocal and multiplying by 10 times. Since the physiological information recording device 1 converts the potential of the electrocardiogram into a frequency by a predetermined function, the potential data is converted into the potential data from the frequency f using the inverse function and recorded (S-21). Then, the peak counter PC and the sampling counter SC are reset to 0 (S-2).
2) Return the process to S-13 at the beginning of the loop.

By repeating the loop as described above, data obtained by reproducing the electrocardiogram recorded by the physiological information recording device 1 is sequentially recorded in the storage unit 33 of the physiological information reproducing unit 21 and displayed. It is also possible to display the data as a graph in the unit 23, and to transmit data remotely from the line communication unit 17.

As described above, according to the second embodiment, the first embodiment
Since the physiological information filter 19 and the audio filter 20 are switched by the switch 18 in accordance with the application in the same manner as described above, stable transmission can be performed even if the output frequency of the physiological information recording device 1 is increased.
In addition to being able to convey human voices clearly, when physiological information is used, patients can properly detect their own physiological information,
In addition, since it is possible to communicate remotely after confirming that the acoustic signal has been properly transmitted to the microphone, inappropriate physiological information due to erroneous operation will not be transmitted to the remote place. Can be operated with ease, and usability is improved.

In the above description of the first and second embodiments, physiological information is described as an electrocardiogram. However, since the electrocardiogram has a large amount of data, the effect of high-speed and stable data transmission is particularly large.
Similarly, auscultation data and electroencephalogram data of the heart and lungs have a large data amount and are highly effective. In addition, although the data amount is small in examination items such as body temperature and blood pressure, the effect is the same in achieving both high-speed data transfer and conversation with a remote person using a communication line.

[0053]

As described above, according to the first to third aspects of the present invention, it is possible to transmit human physiological information remotely and accurately with high speed and high resolution through a communication line. In addition, voice can be clearly transmitted for conversation with a remote person.
