Abstract

PURPOSE:To eliminate a case wherein inspection time becomes long owing to the recording of inspection data, to efficiently perform operation for adding, altering, and referring to data generated after the inspection, and to provide a backup function for a part of data. CONSTITUTION:This system is equipped with a magnetic disk device 12 which temporarily stores inspection data including image data generated by endoscope inspection, and a magnetooptic disk device 13 which stores the inspection data transferred from the magnetic disk device 12. It is judged whether or not prescribed data which are high in accuracy being final data input after the inspection are inputted (input of pathological inspection data and input of final diagnostic result) and when it is judged that the data are already inputted, a file controller 11 transfers the inspection data from the magnetic disk device 12 to the magnetooptic disk device 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data file system for recording inspection data consisting of image data obtained by a medical diagnostic device such as an endoscope device and incidental information thereof, and more particularly to a memory mechanism. Relates to a data file system in which an external or internal storage device having a short access time and a large-capacity storage device having a large storage capacity are provided side by side.

[0002]

2. Description of the Related Art A huge amount of test data including image data is often generated in a medical test in a clinical setting such as an endoscopic test. Therefore, a data file system for storing such inspection data usually includes a large-capacity storage device having a large storage capacity (a magneto-optical disk (MOD) device or an optical disk auto changer (ODAC)).

However, since this large-capacity storage device generally has a long access time (slow response), an external storage device such as a magnetic disk device (hard disk (HD) device) is generally installed alongside this external storage device. After the inspection data is stored once in, the inspection data is stored in the mass storage device.

As a result, it is not necessary to transfer the inspection data to the mass storage device simultaneously with the inspection. In other words, it is possible to eliminate the state of recording in a mass storage device with a long access time (slow response) at the time of inspection, and it is possible to prevent the inspection time from being prolonged. Prolonging the examination time means uncomfortable time for a patient inserting the scope of the electronic endoscope, for example, and is not preferable. By using an external storage device, such unpleasant time can be shortened as much as possible.

The inspection data stored in the external storage device is then transferred to and recorded in the mass storage device at an appropriate timing. The transfer timing is
(I): Transfer / record when the external storage device is full of memory, (ii): Transfer / record at a fixed time, and appropriate transfer timing is selected as necessary. .

[0006]

However, in the above-mentioned (i) -th transfer method (transfer / record when the external storage device is full of memory), if the storage in the external storage device takes a long time. , In the meanwhile, because there is no backup of external storage device (magnetic disk device etc.),
Data reliability is low.

Further, in the (ii) -th transfer method (transfer / record at a fixed time), it is difficult to select the fixed time. If the certain period of time is too early, the inspection data may still be accessed frequently (reference, change, and addition of the inspection data), but even if it is a mass storage device with a long access time (such as a magneto-optical disk device). There is a problem that the data processing efficiency is lowered because the data must be accessed. On the contrary, if the fixed time period to be selected is too long, there is no data backup of the external storage device during that time, as in the case of (i) above.

The present invention has been made in view of the above-mentioned problems of the prior art, and can eliminate the situation that the inspection time is prolonged due to the recording of the inspection data, and can add, change, or refer to the data generated after the inspection. It is an object of the present invention to be able to efficiently perform the above work, and also to have a part of a data backup function.

[0009]

To achieve the above object, in a data file system according to the present invention, a storage device for temporarily storing examination data including image data generated by a medical examination, and this storage device. And a mass storage device for storing the inspection data transferred from the device. Further, a judgment means for judging whether or not a predetermined data input having a high degree of accuracy, which is the final data input after the inspection, is made, and when the judgment means makes a judgment that the predetermined data has been inputted, from the storage device And a transfer control means for transferring the inspection data to the mass storage device.

For example, the determining means is means for determining data input for inputting the result of the pathological examination after the endoscopic examination. Further, the judging means is means for judging data input for inputting the final diagnosis name after the endoscopic examination.

[0011]

According to the present invention, the determination means allows the predetermined data input which is the final data input after the examination with high accuracy (for example, the data input for inputting the result of the pathological examination in the endoscopic examination or the endoscopic examination). When the data input for inputting the final diagnosis name after the inspection) is determined, the transfer control means instructs the transfer of the inspection data from the external or internal storage device to the mass storage device. In other words, until the pathological test result and the final diagnosis name are input, it is very likely that the test data will be referenced, changed, or added, but the test data is stored in the storage device, so Can be accessed at high speed. On the other hand, after the pathological examination result and the final diagnosis name are input, the examination data is transferred to the mass storage device. However, since the inspection data is rarely accessed after this stage, there is almost no problem even if the inspection data is stored in the mass storage device with a slow response. On the other hand, since the inspection data at the time of inspection is stored in the storage device with short access time, the inspection time does not become long due to this data storage. further,
Since the inspection data is transferred to the mass storage device as needed,
After this transfer, there is less risk of being stored in the storage device for an extremely long time, and double storage is performed by both storage devices until the stored data in the storage device is erased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In addition, this Example demonstrates the case where it implemented about endoscopy.

First, the outline of the endoscopic examination will be described with reference to FIG. As shown in the figure, the patient undergoes an endoscopic examination after being booked (for example, one week before) and accepted (the previous day or the same day). At this time, patient information (patient name, patient number, etc.), examination information (date, apparatus name, etc.), examination doctor name, etc. are registered in the endoscope data file system and filed in an external storage device.

Image data is generated by the endoscopic device by the endoscopic examination, and the image data is temporarily stored in the external storage device together with the supplementary information (patient information, examination information, diagnostic information). At this time, a part of the living body is taken by forceps or the like from a region of interest to the doctor who is operating the endoscope while looking at the monitor screen (biopsy). If there is an affected area, a photograph of the affected area is also taken. When the endoscopic examination is completed, the recorded image is usually reproduced, and a part or all of the examination result is explained to the patient. In particular, if there is no disease, the examination ends at this stage.

A part of the collected living body is sent to a pathological examination, and the examination result becomes clear after a certain period (for example, one or two weeks). The examination result is written into the lesion site item or pathological examination item of the examination data (image data and incidental information) temporarily stored in the external storage device at an appropriate time (see step A in FIG. 4). Similarly, the findings of the doctor were added,
Finding items in the inspection data are filled in (Step B in FIG. 4).
reference).

On the other hand, although there is a suspicion of illness, there is a case where the conclusion cannot be reached only by the endoscopic examination and it is necessary to make a comprehensive diagnosis in comparison with the results of other examinations. in this case,
Usually a conference is held. In other words, a large number of doctors participate and the examination is conducted on the basis of the collected test results to give a comprehensive diagnosis result. Although this period varies depending on the hospital, it is within 2 weeks after the examination, for example. This comprehensive diagnosis result is also added to the inspection data in the external storage device at an appropriate time (see step C in FIG. 4).

When the test results are collected as described above, an interview with the patient is held and the medical condition is explained.

FIG. 1 shows an endoscope data file system 10 as a data file system according to the present invention. The endoscope data file system 10 includes a CPU
A file controller 11 having 11a, a magnetic disk device 12 (which constitutes an external storage device of the present invention) and a magneto-optical disk device 13 connected to the file controller 11.
(Which constitutes the mass storage device of the present invention) and the input / output device 14
It has and.

The file controller 11 stores the inspection data (consisting of image data and incidental information: see FIG. 2) in the magnetic disk unit 12 and the magneto-optical disk unit 13 by the processing of the CPU 11a, and at the same time stores the stored data. It is readable.

An endoscopic device 15 as an inspection device is connected to the file control device 11, and the obtained endoscopic image data can be output to both the disk devices 12 and 13 via the file control device 11. Has become.

The magnetic disk device 12 and the magneto-optical disk device 13 are selectively used according to their characteristics (long access time, large storage capacity). In other words, data that is highly likely to be accessed frequently and that is likely to be added or changed is processed quickly because of the operational efficiency.
It is stored in the magnetic disk device 12 which has a short access time. On the other hand, although the necessary additions and changes have already been completed and the possibility of access has decreased, the data that needs to be saved is saved in the magneto-optical disk device 13. Since this data is rarely accessed, it does not have to be a high-speed access. In consideration of the transfer timing to the magneto-optical disk device 13, the magnetic disk device 12 has a storage capacity of, for example, 200 MB to 400 MB per inspection device.

When the magnetic disk device 12 and the magneto-optical disk device 13 are properly used as described above, it is necessary to transfer the inspection data from the former to the latter. The transfer timing in this embodiment is set as follows.

(A): When a part of the tissue of the living body is collected during the endoscopic examination and sent to the living body examination, the result of the pathological examination is input (see step A in FIG. 4). This is due to the fact that access to test data is much less necessary after the results of the pathological examination are known and the histological diagnosis of the lesion is made. This period is, for example, 1 to 2 weeks after the examination. (B): Suspected illness, but no conclusion can be drawn only by endoscopy, and a conference is held to refer to other test results, and the final diagnosis of illness is made from comprehensive detection there (Fig. See Step C of 4). This period is, for example, within 2 weeks after the examination. (C): The inspection data other than the above (a) and (b) has almost no possibility of data change / addition, but there is a possibility of referring to the inspection data. Forward. The user can arbitrarily set this fixed period.

The CPU 11a of the file control device 11 is
Input process of incidental information at the time of registration performed through the input / output device 14, input process of image data at the time of inspection sent from the endoscope device 15, and inspection performed through the input / output device 14. While performing data processing such as data reference, addition, and change based on a predetermined program, FIG.
The inspection data transfer process is performed based on the program shown in FIG. The program of FIG. 3 is automatically started at a time preset by the system (for example, a predetermined time at night after the inspection is completed).

First, when the program is activated and a transfer request is started (step 20), the process proceeds to step 21,
For each of the examination data stored in the magnetic disk device 12, whether or not there is a biopsy number (that is, whether or not a biopsy is performed) is used as information of the biopsy number item (see FIG. 2) in the accompanying information. Judge based on

When it is determined in step 21 that YES has been made for a certain piece of test data, that is, it has been determined that a biopsy has been performed, it is determined in step 22 whether or not the pathological test result has already been input for that test data. . Y in this judgment
ES, that is, a pathological examination result is input (step A in FIG. 4).
(See), the inspection data is transferred (recorded) from the magnetic disk device 12 to the magneto-optical disk device 13 in step 23.

Thereafter, in step 24, it is judged whether or not all the inspection data stored in the magnetic disk device 12 are checked, and if NO, the process proceeds to step 21 to check the inspection data of the next patient. Return. If YES, the transfer process ends.

On the other hand, if it is determined NO in step 22, that is, if the pathological examination result has not been input, data transfer is not instructed. For this reason, the unentered examination data of the pathological examination result is stored in the magnetic disk device 12 as it is. Then, the process returns to step 21 through step 24.

On the other hand, when the result of the step 21 is NO, that is, when the biometric examination is not performed on the examination data, the decision of step 25 is made. That is, whether or not the result of the final diagnosis is input is determined by determining the final diagnosis item (see FIG. 2) in the diagnostic information in the supplementary information. Here, final diagnosis (see step B or C in FIG. 4)
When there is a first diagnosis item, a second diagnosis item, etc., is the item showing the definite diagnosis.

If the determination in step 25 is YES (the final diagnosis result has been input), the process proceeds to step 23 and transfer processing is performed. When the result is NO (the final diagnosis result has not been input), the process proceeds to step 26, and it is determined whether or not a certain period set by the system has passed. Here, the certain period is a period until the period (for example, one week) for storing the inspection data, which has already been able to give the diagnosis result at the time of inspection, in the magnetic disk device 12, elapses in the system. It can be set arbitrarily.

When YES is determined in step 26 (passage of a certain period of time), the transfer process described above is performed in step 23. If NO (a certain period has not passed since the inspection), it is determined that the frequency of any access to the inspection data is still high, and the process returns to step 24. As a result, the inspection data to be checked is continuously stored in the magnetic disk device 12. After this, step 2
If it is determined in 4 that the inspection data that has not been checked remains, the series of processes described above is repeated.

When the inspection data is referred to, added to, or changed by performing the transfer processing as described above, the magnetic disk device 12 may be accessed in most cases. Therefore, those processings can be performed at high speed to improve work efficiency. Can be increased.

In most cases, the inspection data that is no longer required to be accessed but is desired to be saved is the magneto-optical disk device 13.
Is transferred to and stored in. In most cases, the inspection data of the magnetic disk device 12 is erased because it is transferred at an appropriate timing in consideration of the access frequency, such as after the pathological inspection result is input before the memory capacity of the magnetic disk device 12 is full. Up to this point, the same inspection data is stored in the magnetic disk device 12 and the magneto-optical disk device 13 in duplicate, so that it also serves as a backup function for the inspection data and increases the reliability of data preservation.

Further, since the image data generated at the time of the examination is temporarily stored in the magnetic disk device 12, the examination is prolonged for the data storage and the discomfort of the patient is not promoted.

The storage device according to the present invention is not limited to an external magnetic disk (hard disk) device, and may be any storage device having a short access time. Further, as this storage device, for example, an internal storage device provided inside the file control device may be used. Further, the mass storage device may be an optical disc auto changer equipped with a plurality of optical discs.

Further, the transfer timing judgment criterion according to the present invention omits "after inputting the final diagnosis result" or "after inputting the pathological examination result" and omits "after inputting the pathological examination result" or "final diagnosis result". “After inputting” and “After a certain period of time has passed after the inspection”.

Furthermore, the data file system of the present invention is not limited to endoscopic examination, but may be applied to ultrasonic examination or ultrasonic endoscopic examination, for example.

Further, in the above-mentioned embodiment, it is once judged whether all the inspection data of the magnetic disk device can be transferred, and the inspection data which can be transferred are rearranged and classified by paying attention to a specific attribute. It is also possible to add a method of transferring them all at once.

[0039]

As described above, according to the present invention, the inspection data is transferred from the storage device to the mass storage device when a predetermined data input having a high accuracy, which is the final data input after the inspection, is determined. In addition, it is possible to efficiently access the storage device at high speed in most cases to add, change, and refer to the data that occurs after the inspection without increasing the inspection time for recording the inspection data. Further, until the stored data in the storage device is erased, the data backup function is enhanced due to the dual storage by both storage devices. Therefore, a data file system that is easy for patients to undergo examinations, easy for operators to manage data, and has high data integrity,
It can be provided with a simple configuration.
