1: This area is a data registration area for the file name "Vital 1" described in the data registration area information area 49 described above, and is composed of two parts, a command table 52 and a record recording area 53. Of these, the data registration number in the command table 52 refers to the number of measurement items that are collectively stored in one record by one measurement recording operation. Here, three items 1 to 3 can be registered. ing.

Looking at item 1, the biosensor identification code (hereinafter referred to as sensor ID) is "01",
The numbering is "01". The data type is "4". As shown in FIG. 5, the sensor ID
“01” indicates a sphygmomanometer, and numbered “01” and “02” indicate the upper and lower values of blood pressure, respectively, as measurement items. The sensor ID "02" indicates a pulse rate meter, and the measurement item is the pulse rate. Further, the sensor ID “03” indicates a thermometer, and the measurement item is body temperature.
The sensor ID “04” indicates a heart rate meter, and the measurement item is the heart rate.

Further, as shown in FIG. 6, for example, the data type "02" indicates an unsigned 1-byte type, and the byte length is 1 byte. Therefore, the effective range is 0 to +255. These data types are appropriately selected depending on the measurement item. Now, regarding item 1 of the command table 52 in FIG. 3, as can be seen from FIGS. 5 and 6, the sensor ID “01” indicates that the sensor uses a blood pressure monitor, and the number “01” indicates the blood pressure.

A record recording area 53 is provided in an area following the command table 52. In the record recording area 53, record numbers and data indicating record contents are associated and cumulatively recorded. Each record has a fixed length, and is a collection of the data obtained for each of the measurement items of item 1 to item 3 described above. Specifically, it has a record structure as shown in FIG.

(Iv) Data registration area "Vital 2" 55:
This area is a data registration area for the file name “Vital 2” described in the data registration area information area 49, and is composed of two parts, a command table 56 and a record recording area 57. Of these, the number of data registrations in the command table 56 is 2, which indicates that two items, item 1 and item 2, are combined into one record by one measurement recording operation. Of these, item 1 indicates that the body temperature data measured by the thermometer is recorded in the floating point type 2 data type, and item 2 records the heart rate measured by the heart rate meter in the unsigned 1-byte type data type. It shows that you do.

Further, following the command table 56, there is provided a record recording area 57 for recording a record corresponding thereto. Here, each record has a record structure in which the data measured for the above-mentioned two items, item 1 and item 2, are summarized, and specifically, has a record structure as shown in FIG. There is.

By thus dividing the data registration area into two, the user can perform measurement recording without error when it is necessary to measure a plurality of types of measurement items at different times. That is, for example, as shown in FIG. 7, when it is necessary to measure blood pressure and pulse rate twice daily at 8:00 and 16:00, and body temperature and heart rate twice at 16:00 and 20:00, As described above, the above registration instruction information necessary for measuring the blood pressure and the pulse rate is stored in the command table 52 of the data registration area “Vital 1” 51, and the registration instruction information necessary for measuring the body temperature and the heart rate is registered. It is stored in the command table 56 of the area “Vital 2” 55. Then, the patient or the like attaches a predetermined sensor at a predetermined time to make a measurement, and presses a memory button provided on the home adapter, so that the measurement items designated in these two data registration areas are separated from each other. Will be recorded in the record recording areas 53 and 57. By performing such an operation every day, the records having the determined data lengths are cumulatively additionally recorded in the two record recording areas 53 and 57.

FIG. 8 shows the data structure of the records recorded in the record recording areas 53 and 57, respectively. Of these, FIG. 8A shows the record structure of the record recording area 53, and the date 61, the blood pressure upper limit 6
2, the lower blood pressure value 63, and the pulse rate 64. The date is 6 bytes, and the upper and lower blood pressure are 2 each
A byte and a pulse rate are represented by 1 byte. Therefore, this record has 11 bytes as a whole.

Further, FIG. 7B shows the record recording area 5
7 shows the record structure of No. 7. This record is composed of a date 65, a body temperature 66 and a heart rate 67. Here the date is represented by 6 bytes, the body temperature is represented by 4 bytes, and the heart rate is represented by 2 bytes. Therefore, the total record length is 12 bytes.

In this way, the record recording areas 53 and 5
The record lengths of 7 do not necessarily have to be the same, and generally differ. Therefore, when these are recorded together, so-called data gaps are scattered here and there. By dividing the recording area for each record length in this way, this is prevented and the memory area Effective use becomes possible.

The operation of actual data recording on this IC card will be described below with reference to FIG. First, when the user arrives at a predetermined time, the user connects a biosensor specified in advance to any one of the connection channels 1 to 3 of the biosensor interface unit 23 of the home adapter 1, and the sensor unit It is attached to a predetermined part of the body and the measurement is performed by a predetermined operation. As a result, the measurement data is temporarily stored in the RAM 34 of the biosensor.

Next, when the IC card 25 is attached to the IC card reader / writer unit 22 and a registration button (not shown) of the home adapter 1 is pressed (step S101; YES), CP
U12 turns on the power supply to the IC card 25 (step S102). Then, the CPU 12 detects whether or not a predetermined serial test signal is transmitted from the IC card 25 and confirms whether the IC card is operating normally (step S103). As a result, if it is normal (step S103; Y), the IC card is authenticated next (step S104), and if it is not normal (step S103).
103; N), the power of the IC card 25 is turned off (step S121), and the IC card is ejected (step S12).
At the same time, the hands-free telephone 17 or the synthetic voice generation circuit 19 is used to notify the user by voice of the abnormal termination (step S123).

If the IC card has not been successfully authenticated (step S105: NO), the above step S12 is performed.
Go to 1 and terminate abnormally. If the authentication is successful (step S105; YES), the CPU 12 causes the data registration area information area 4 of the EEPROM 47 of the IC card 25.
The contents of 9 are read (step S106). As a result, “02” is stored as the number of data registration areas and “Vital 1” and “Vital 2” are stored as the data registration area file names in the RAM 14 of the home adapter. Here, when the number of registered areas is “0” (step S
107; Y), the power of the IC card 25 is turned off (step S117), and the IC card 25 is ejected (step S).
At the same time, the user is notified by voice of the normal end (step S119).

Next, the CPU 12 confirms whether or not any sensor is connected to the channels 1 to 3 of the biosensor interface unit 23 (FIG. 1) (step S10).
8). If the sensor is not connected to any of the channels (step S109; NO), the process proceeds to the above step S120 and ends abnormally. On the other hand, when the connection of the sensor is confirmed in any of the channels (step S109: YES), the sensor ID, number, and data of each sensor are read from the ROM 33 of the connected biosensor for each channel. The type is read (step S110).

Next, the EEPROM 49 of the IC card 25
The command table 52 is read from and stored in the RAM 14 of the home adapter (step S110). And C
The PU 12 acquires the biosensor data instructed by the command table from the corresponding channel (step S112), and edits it so that it can be written in the IC card (step S113).

Next, the CPU 12 checks whether or not another command table remains, and if any other command table remains (step S114; YES), the operations of steps S112 and S113 are repeated. This allows the EEPROM
The command table 56 in 49 is read and RAM1
4 and the biometric sensor data corresponding to this command table is acquired and undergoes the editing as described above.

When there is no command table to be read (step S114; NO), the CPU 12 waits until the memory button (not shown) is pressed. When the user presses the memory button (step S1
15; YES), the CPU 12 reads the edited data on the RAM 14 and writes it in the record recording areas 53 and 57 on the IC card 25 via the SIO unit 21 and the IC card reader / writer unit 22 (step S116). As a result, the record as shown in FIG. 8A is recorded in the record recording area 53, and the record as shown in FIG. 8B is recorded in the record recording area 57.

If the writing is not normally performed (step S117; NO), the process proceeds to step S121 described above, and an abnormal end is notified by voice (step S123).

On the other hand, if the writing is normally performed (step S117; YES), the power of the IC card 25 is turned off (step S118), the IC card is ejected (step S119), and the user is informed. Then, the normal termination is notified by voice (step S120).

As described above, in this embodiment, the items to be measured at the same time are collectively stored in one command table, and a plurality of such commands tables are provided, so that the user only operates one memory button at different time intervals or different values. Even when the measurement is requested in different time zones, the desired data can be stored in the desired areas of the IC card separately and very easily and without error. This makes it possible to use the storage area of the IC card very efficiently, and
It becomes very easy to use the data stored in the IC card later.

In the record recording area, it is sufficient to secure an area capable of storing records for the required number of days. When the area becomes full, data is transmitted to the center by using the telephone line. Or, to the hospital IC
After bringing in the card and reading the data, you can overwrite the oldest records in order.

Further, in the present embodiment, the biosensor interface section 23 is provided with three sensor connection channels, but since the sensor ID is constantly checked, whichever biosensor is connected to which channel, the elderly Even a person unfamiliar with machine operation such as can perform the connection operation without being aware of the channel.
