DISCLOSURE OF THE INVENTION In order to solve the above problems, the present invention employs the following technical means.

The distributed inspection / measurement system according to the present invention comprises a central management device and a plurality of inspection / measurement terminal devices connectable to the central management device via a communication line. The apparatus includes a data collection unit that collects data from a sample, and a data transmission unit that transmits data collected by the data collection unit to the central management device.The data collection unit measures a reference sample. The central management device includes data adjustment means for adjusting the data by comparing the maintenance data received from the terminal device with a reference value and collecting the maintenance data. It is characterized by:

Each terminal device measures a sample to be measured and collects measurement data. In addition, each terminal device also measures a reference sample provided in advance in a data collection unit and collects the data as maintenance data. These measurement data and maintenance data are transmitted to the central management device via a communication line. In the system according to the present invention,
In the case where a plurality of terminal devices are connected to the central management device via a communication line and the central management device performs statistical processing of measurement data, the number of installed terminal devices may be enormous. Also in this case, the reference samples provided in each terminal device are samples of the same standard.

When the data collection unit of the terminal device is configured to amplify the output from the sensor unit by the amplifying unit, the data collection unit conforms to the same standard due to variations in initial settings of each terminal device and changes over time. Even when the reference sample is measured, the output level of the amplifying unit may vary. That is, the gain and offset amount of the amplification unit may be different for each terminal device. In the present invention, the maintenance data obtained from the reference sample is compared with a reference value corresponding to the reference sample in the central management device to adjust the data. Specifically, for example, when adjusting only the gain of the amplifying section, the ratio between the value of the maintenance data and the reference value is used as an error coefficient, and the sample to be measured is measured using the error coefficient. It adjusts the data obtained. Further, when adjusting up to the offset amount, two types of reference samples are measured, a function representing the characteristic of the amplifying unit in the terminal device is specified, and data is adjusted using this function.

In a preferred embodiment, each terminal device collects raw data of a sample and transmits the collected raw data to a central management device. The central management device calculates the raw data and obtains measurement data. I have. In this case, data obtained by measuring the reference sample is also raw data. The central management unit adjusts the data at the stage of the raw data, or performs adjustment at the stage of the data after the operation.

In any case, as a result of such a configuration, according to the distributed inspection / measurement system according to the present invention, the number of terminal devices for inspection / measurement is enormous and the characteristics of each terminal device are Even if errors occur in the measurement data due to variations or changes over time, the central management unit can centrally manage such data errors without the need for maintenance work on each terminal device. Correction allows accurate measurement data to be accumulated.

In a preferred embodiment, the raw data collection section in each of the terminal devices measures a calibration sample and collects calibration raw data necessary for calculating measurement data from the measured raw data. The apparatus further comprises raw data collecting means, wherein the data calculation means in the central management device receives the measured raw data received from each terminal device or the measured raw data adjusted by the data adjusting means, and received from each terminal device. Data calculation means for generating measurement data using the raw data for calibration is included.

That is, for example, when the system of the present invention is configured to measure the concentration of a specific component in urine by spectroscopic analysis, each terminal device has
In addition to the reference sample used to centrally correct the data error mainly due to the variation in the output level of the amplification unit in the central control unit, for example, preferably a plurality of calibration samples having a prescribed concentration are prepared in advance. Be equipped. Based on the raw data for calibration obtained from such a calibration sample, the central control unit creates a calibration curve, and in accordance with the calibration curve, the concentration of the characteristic component in the sample to be measured, that is, the urine sample set by the patient. Is calculated. Even in this case, since all the raw data are error-adjusted as described above, the measurement data thus accumulated is accurate regardless of the variation in the characteristics of the amplifying unit for each terminal device. It will be. In the present invention, raw data refers to output data before having meaning as clinical data in the case of the above-described clinical test. That is, it is data at a stage where an output value using an optical method, an electrochemical method, a photoacoustic method, or another method suitable for a measurement object is converted into an electric signal. The raw data collected in this way is transmitted to the central management device via the communication line, and after the above-described data adjustment, analysis and calculation (calibration) are performed for the first time in the central management device, and the data is converted into clinical data. This gives meaningful measurement data.

[0015] In this way, for example, in the distributed health care system of the above example, the terminal device to be installed in the patient's house measures the test object (including each sample) as a basic function and obtains the raw data. It is sufficient to have the minimum function of generating the raw data and transmitting this raw data to the central control device via a communication line. The concentration of the specific component in the measurement sample is determined by the analysis and calculation (calibration) algorithm. It is not necessary for each terminal device to have a complicated function such as calculating the value.

In a preferred embodiment, the raw data collection unit in the terminal device includes an output level adjustment unit that operates according to a command from a central management device.
When the deviation of the raw maintenance data received from the terminal device from the reference value is equal to or larger than a predetermined value, the central management device outputs a terminal data output command to adjust the data output level of the terminal device as predetermined. It has level adjustment means. The adjustment of the data output level is performed so that the deviation of the raw maintenance data from the reference value is eliminated. Of course, even if the error of the raw data for maintenance cannot be eliminated by this output level adjustment, the accuracy of the measurement data is ensured by using the data adjustment means built in the central management device together. Can be.

In a preferred embodiment, when the deviation of the raw maintenance data received from the terminal device from the reference value is equal to or greater than a predetermined value, the central management device notifies the terminal device that the terminal device is abnormal. It has a notifying means.

In such a case, the terminal device malfunctions to such an extent that the measurement data cannot be corrected by adjusting the terminal data output level or by the operation of the data adjusting means performed in the central management unit. is there. For example, such an abnormality notification is issued to a system maintenance company or a terminal device. Only in such a situation does each terminal device undergo maintenance and inspection work by maintenance personnel.

Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the drawings.

A terminal abnormality notification unit 234 for performing terminal abnormality notification when the maintenance raw data indicates a malfunction or abnormality of the terminal device is included.

Next, the terminal device 30 and the central management device 2
An example of the operation of 0 will be described.

First, FIG. 6 is a flowchart showing an example of the operation of the terminal device 30. For example, a diabetic home patient sets a measurement sample in which urine collected preferably at a predetermined time every morning is placed in a predetermined cell in the sample loading section 41 of the terminal device 30 installed at home.
When the measurement sample is set in this way (S101:
YES), the raw data collection unit of the terminal device 30 automatically measures the reference sample 42A, the calibration sample 42B, and the measurement sample 42 sequentially, and collects the maintenance raw data, the calibration raw data, and the measured raw data ( S102, S1
03, S104). Each of the raw data is data amplified by the amplification unit 45 under predetermined amplification conditions.

The raw data for maintenance, the raw data for calibration, and the raw data for measurement are then automatically transmitted to the central management unit 20 by the data transmitting means (55 in FIG. 5) (S105). More specifically, the electric signal is
After being A / D converted, it is transmitted via the modem 36.
In this case, an ID code for specifying the individual terminal device 30 or the patient corresponding to the terminal device 30 is added to the transmission data.

Next, when an output level change and data retransmission command are received from the central management unit 20 for the raw data previously transmitted within a predetermined time (S105: YE
S), the amplification condition of the amplification unit 45 is adjusted based on the command, and the steps of S102 to S105 are repeated. S
When the amplification condition change and the data retransmission command are not received from the central management device 20 in 106 (S106:
NO), the process ends.

FIG. 7 is a flowchart showing an example of the processing of the central management unit 30. When the above-mentioned raw data, that is, raw data for maintenance, raw data for calibration, and raw data for measurement are received from the terminal device 30 (S201: YE
S), the ID code of the data is checked to specify which patient the data is related to (S202). Next, the value of the raw maintenance data is compared with a reference value, and it is determined whether the deviation is equal to or less than a first set value (S2).
03). That is, the reference value of the raw data to be obtained by measuring the maintenance sample of the same standard equipped in all terminal devices 30 is compared with the raw data for maintenance actually transmitted from each terminal device 30. Therefore, if there is a deviation between them, the raw data sent from the terminal device 30 includes an error due to a deviation in the output level of the amplification unit of the terminal device. Means If this error is due to a deviation in the gain of the amplification unit, the value of the raw data for maintenance is divided by a reference value to obtain an error coefficient, and the raw data for measurement is divided by this error coefficient to obtain a measurement. Errors are removed from the raw data. S20 above
In S3, when the deviation between the value of the raw data for maintenance and the reference value is equal to or smaller than the first set value, in S204, the raw data adjustment for removing the error from the raw data using the error coefficient is performed. Done. Note that the output level shift of the amplifying unit 45 between the terminal devices may include the offset amount shift in addition to the gain shift as described above, and the output level is adjusted in such a case. In order to
At least two types of reference samples are measured to check the linear characteristic of the amplification unit, and the raw data to be measured is adjusted based on the linear characteristic. In addition, the raw data to be adjusted include raw data measured from a measurement sample and raw data for calibration obtained from a calibration sample. This is because each of them is output via an amplifier in which an output level shift occurs.

Next, the measurement data is calculated (calibrated) from the measured raw data adjusted as described above (S20).
5). Specifically, a calibration curve is created from the above-prepared raw data for calibration obtained from the two types of calibration samples, and from this calibration curve, the urine corresponding to the value of the above-mentioned raw data for adjustment after adjustment is obtained. Calculate the concentration of the specific component.

It is determined whether the measurement data as clinical data thus obtained is normal in the light of the normal range as a group (S206), and if abnormal (S206: YES), an abnormality report is issued. (S21
4). Specifically, this abnormality report is transmitted by transmitting an abnormality report signal to the terminal device 30 and displaying it on the display unit 39,
This is performed, for example, by reporting to the medical institution 60 to which the doctor in charge of the patient belongs by communication. And the medical institution 60
When the above-mentioned abnormality report is made, the above-mentioned abnormality data is also transferred to the medical institution 60 (S215).

The clinical data is subjected to individual statistical processing (S207) and population statistical processing (S208). That is, in the individual statistical processing, the same I
Clinical data is accumulated for each D code, and predetermined statistical processing is performed. When performing long-term home treatment, by accumulating the above clinical data for each individual, it will be possible to define the normal range as the individual patient,
The normal range is usually smaller than the population normal range. Therefore, by checking the clinical data collected every time in the light of the individual normal range, it is possible to finely manage changes in the health status of home patients. In the group statistical processing, a predetermined statistical processing is performed on all clinical data regardless of the ID code, and a normal range as a group is defined.

In S203, if the deviation of the raw maintenance data from the reference value is larger than the first set value (S203: NO), the deviation of the raw maintenance data from the reference value is equal to or less than the second set value. Is determined (S211). Usually, the second set value is set to be larger than the first set value. If the deviation is equal to or smaller than the second set value (S211: YES), an amplification condition change and data retransmission command are transmitted to the terminal device 30 (S212). That is, in this embodiment, when the deviation of the output level of the raw maintenance data transmitted from the terminal device 30 is relatively small, the data of each raw data is processed in the internal processing of the central management device 20 as described above. Adjustment is performed, but when the deviation of the output level is relatively large, it is not changed by the data adjustment in the central management device 20 but is changed by changing the amplification condition of the amplification unit of the terminal device 30. The processing in the terminal device 30 that has received such a change in the amplification condition and the data retransmission command is as described above. From the terminal device 30,
The raw measurement data and the raw calibration data collected after the change of the amplification conditions are retransmitted. In this case, S201 to S201
Step 203 is executed again.

In S211, if the deviation of the raw data for maintenance from the reference value is larger than the second set value (S211: NO), the terminal device 30 will be out of order to the extent that maintenance is required. As an event, a terminal abnormality notification is made (S213). Specifically, the terminal abnormality notification is performed to a system maintenance company, a terminal device, or a related medical institution of the distributed health care system, and a medical accident prevention measure is taken.

The raw data for maintenance and the history of changes in amplification conditions
It is subjected to terminal-specific maintenance data statistical processing, for example, how the deviation from the reference value changes over time,
Alternatively, how the amplification condition was changed is recorded. By such a statistical process, for example, it is possible to predict a change tendency of the deviation of the raw data for maintenance, and thereby, it is possible to predict a maintenance inspection time of the terminal device 30 and the like.

The raw maintenance data and the history of the amplification condition change are also subjected to maintenance data statistical processing for all terminal devices (S210). As a result, for example, the overall tendency of the deviation of the raw maintenance data from the reference value can be determined, and such information can be effectively used for system maintenance.

As described above, in the distributed health management system 10 according to the present embodiment, the raw data collection section 40 provided in each terminal device and the measurement data calculation means 210 provided in the central management device 20 are provided. Collaborate to demonstrate a complete clinical laboratory function. That is, the central management device 20 composed of a large-sized computer collectively takes charge of the function of executing the calculation using the raw data to obtain measurement data that has meaning as clinical data. Therefore, the terminal device 30 to be installed at the patient's home can be configured as a simple device having a minimum required function of a raw data collection function and a data transmission function. Therefore, the terminal device 30 is relatively inexpensive, and a patient who desires this kind of home health care service or home treatment support service can receive such a service with a relatively low economic burden. .

The fact that such a terminal device can be provided at low cost is extremely significant from the viewpoint of statistical processing of clinical data. That is, a large number of installed terminal devices 3
Since a large amount of data transmitted from 0 can be used as a population, more accurate statistical processing can be performed.

Further, the data error caused by the output level deviation of each terminal device 30 is obtained by, for example, using the raw maintenance data obtained by measuring a reference sample of the same standard provided in each terminal device 30. This can be substantially eliminated by a simple technique, for example, by comparing this raw maintenance data with a reference value in a central control unit and adjusting the measured raw data based on the result. In addition, the central management device can recognize the abnormality of the terminal device based on the tendency of the error. Therefore, the reliability of the measurement data as clinical data which is stored in the central management device and used for grasping the health condition of the patient and statistically processed can be significantly improved. Further, when a huge number of terminal devices 30 are connected to the central management device 20 to construct a distributed inspection / measurement system, maintenance management of each terminal device is significantly simplified. As described above, the present invention makes it possible for the first time to realize a reliable distributed inspection / measurement system having a huge number of terminal devices on the premise of statistical processing.

Of course, the scope of the present invention is not limited to the above embodiment. For example, in the above embodiment, as shown in FIG. 3, the raw data collecting unit 40 included in each terminal device 30 collects raw data to measure a specific component in a sample by a spectroscopic analysis method. However, in a case where raw data is collected by an electrochemical method, a configuration shown in FIG. 8 can be used. That is, the sample loading unit 41 including the measurement electrode 421 and the counter electrode 422, and the plurality of reference resistors 42A, 42B, and 42C corresponding to the difference in concentration are arranged in parallel,
The sample loading section 41 and each of the reference resistors 42A, 42
B and 42C can be switched to and connected to the amplifier 45 via the changeover switch 42S. The amplification unit 45
The output level can be adjusted by the output level adjusting unit 46 in accordance with a command from the central management device 20. In this case, one or more of the plurality of reference resistors function as a reference sample, and one or more of the plurality of reference resistors function as a data calibration sample.

In the embodiment, the raw data is collected in the terminal device and sent to the central management device for processing. If possible, for example, measurement data having clinical significance is collected. Even when it is obtained at each terminal device and transmitted to the central management device for statistical processing,
Similarly, the present invention can be applied. In short, the invention of the present application adjusts data in the central management device, that is, in order to adjust an error in data caused by a shift in the output level of the amplifying unit, measures a reference sample in each terminal device and collects maintenance data. It was intended to be collected,
All distributed inspection and measurement systems that employ this concept are all within the scope of the present invention.

Further, as a means for performing calibration in the central control device using the calibration data, a case where a plurality of urine components are simultaneously quantitatively analyzed using a multivariate regression analysis method is, of course, included in the scope of the present invention. You.

Further, in the above-described embodiment, every time the terminal device collects raw data of a measurement sample, the terminal device collects raw data of a reference sample, that is, raw data for maintenance of the terminal device. Although transmitted to the central management device, for example, raw data for maintenance may be collected and sequentially transmitted to the central management device according to a command from the central management device, or may be periodically transmitted. Alternatively, the maintenance raw data may be collected and transmitted to the central management device.
