The use of the patient terminal for a short time and the use for a long time can be stopped with a single key operation. The use of the patient terminal for a short time and the use for a long time can be stopped by the key operation time of the only key operation.

The signal switching section 40 functions when the measurement item information from the motherboard 31 is the stethoscope 5e or the electrocardiograph 5f. Select one of the time-varying signals output from the stethoscope 5e or the electrocardiograph 5f to select the motherboard 3
One of the sound circuits 32 can be converted into a WAV file. The electrocardiograph 5f outputs a measured electrocardiographic signal as a modulated sound, and can be input using a microphone 7b used when performing a TV telephone function.

As described above, biological information that requires time lapse information instead of instantaneous information, such as auscultation signals and electrocardiographic signals, is converted to a WAV file and transmitted to the center server 3 via the communication network 4. It can be stored and observed from the doctor terminal 2 as a time lapse signal.

The signal switching section 40 has an amplifier circuit and can adjust the gain of the input auscultation signal or electrocardiogram signal. This gain setting value is
1 is transmitted to the protocol converter 39 together with the measurement item information of the auscultation measurement or the electrocardiography measurement.
The signal switching unit 40 fulfills its function by the control from. In order to transmit biological information that requires time-lapse information such as electrocardiogram signals in real time, it is necessary to keep the communication line online so communication costs are high. Since short-time transmission is sufficient, communication costs can be reduced.

Reference numeral 42 denotes a power supply device. A first power supply unit 42a for connecting to a commercial power supply 42c to supply power to most of the patient terminal 1, and a second power supply unit for supplying power to the vital sensor side circuit unit 38a of the insulation separating unit 38 42b. At least the second power supply 42
b has a reinforced insulation structure, and the vital sensor 5 that touches the human body together with the insulation separating portion 38 can be completely insulated from the commercial power supply 42c.

FIG. 6 is a flowchart of the operation of the patient terminal 1.
When the patient terminal 1 starts up, first, the communication terminal device 6 is connected to the center server 3 via the communication network 4 and enters an online operation, and performs a start-up process 61. Here, content software update processing of the patient terminal 1, new arrival check of medical advice from a doctor, and processing of untransmitted data such as biological information measured by the patient terminal 1 are performed. By connecting online before the patient uses the patient terminal, the information that determines the functional performance of the patient terminal can be updated.

In the software update process, the version information of the existing software is stored in the patient terminal 1,
This is a process of connecting to the center server 3 via a line, comparing with the latest version information registered in the database server 11, and if different, downloading and replacing the latest version. However, the contents of the software of the patient terminal 1 are optimized for each patient and are different from each other. Therefore,
The latest version of software is the latest version for the patient. Since the change of the content such as the function performance of the terminal can be realized by the work from the center server, a significant work improvement effect can be expected. The patient terminal has a function of comparing the version information of the currently operating software with the version information stored in the center server, and downloading the different information if different, so that a new version of the software can always be used.

The check for new arrival of medical advice from the doctor is performed by setting a new arrival flag in the advice file from the doctor registered in the database server 11 of the center server 3 and resetting the new arrival flag when the patient terminal 1 reads it. In addition to performing new arrival management, the patient terminal 1 displays the menu selection GUI operation screen 6 in FIG. 7 to indicate to the patient that the new arrival advice has been transferred.
This is a process for displaying a new arrival mark 69b as shown in FIG. Since the patient can easily know that the medical advice from the attending physician has arrived, the patient can receive the medical advice at an appropriate timing, and a high medical effect can be expected.

The untransmitted data processing is normally performed when medical information input work such as measurement by the vital sensor 5, input of an answer to a medical inquiry, shooting of a still image by the video camera 7a, etc. is completed.
By operating the transfer button 76 provided on the menu selection GUI operation screen 64a of FIG. 7, the patient automatically operates online to transmit the patient medical information to the center server 3, but forgets to operate the transfer button. When the power is turned on, this untransmitted data is transmitted at the time of the next power-on. Since a plurality of patient medical information such as a plurality of pieces of biological information and medical inquiry response data can be collectively connected and transmitted online at once, an efficient communication network can be used. When the start-up process 61 is completed, the line connection is automatically cut off, the system goes offline, and the process proceeds to the patient name selection process 62. Since the on-line operation and the off-line operation are automatically switched according to the content of the processing, efficient use of the communication line can be achieved without deteriorating the function. In addition, since the number of telephone lines is usually one in ordinary homes, it is also effective in that telephone lines can be shared.

The displayed patient name is already registered from the management terminal of the center server 3, and is displayed unique to each patient terminal 1 together with the number of displayed patients. In the patient registration information registered in the center server 3, an informal unique name such as a nickname can be registered in addition to the official name.

The patient name information is constantly updated to the latest information by the software updating process at the start-up process 61 described above.

When the user name is determined in the patient name selection process 62, the process proceeds to the password input process 63. The password is input by numerical keys 0 to 9 constituted by GUI touch keys. The number of digits is, for example, a maximum of 10 digits, and the number of digits used is free. That is, the digit number information is also used as the authentication information.

The input password is compared with the password information stored for each patient name, and when they match, the process can proceed to the next step. The password information for each patient name is always updated to the latest information by the software update process at the start-up process 61, similarly to the above-mentioned patient name information.

The registration of the password information is performed by a separately provided password registration process.

When the correct password is input, the flow shifts to menu selection processing 64. FIG. 7 shows an example of the GUI operation screen 64a, in which touch keys (65a, 66a, 67a, 68a, 69a,
70a, 71a, 72a) are arranged integrally with the GUI button image.

When the graph display selection process 66 is selected,
Here, the biological information display item to be displayed is determined by the GUI operation screen for selecting the biological information display item. This biological information display item is linked with the biological information measurement item.

When the biological information display items to be displayed are determined, the flow shifts to each biological information display processing 75 to display a graph showing a temporal change of each biological information. FIG. 8 shows an embodiment in the case of a thermometer.

The graph display of the change over time in the patient terminal 1 is performed by downloading a graph display processing program for executing the graph display from the center server 3. That is, the drawing engine software operates in the center server 3, and a graph display processing program for displaying a graph based on long-term biological information stored in the database is created. This graph display processing program is created in a programming language such as the C language, and can be executed by the patient terminal 1 to draw a graph. In addition, since it usually takes time to download,
The biological information already transmitted to the center server 3 is displayed in the above-described manner, and the non-transmitted data measured immediately before is drawn by the patient terminal 1. Visual representation such as graph display of biological information is a heavy processing in terms of computer processing, and if it is performed by a patient terminal or a doctor terminal, the hardware of each terminal becomes expensive. By performing this on the center server, the overall cost can be reduced.

When the question answer input process 67 is selected, the process proceeds to a question item selection process, and the question item is determined on the GUI operation screen.
