The hard disk device 15 also stores a program for controlling the operation of the CPU 12, and the program is transferred to the RAM 13 via the hard disk interface 14,
It is configured to be sequentially read and executed by the CPU 12.

FIG. 7 is a flowchart showing the entire program.

 In FIG. 7, various initializations are performed at P1.

At P2, the main menu shown in FIG. 8 is displayed on the computer display 9. The display is performed by the CPU 12 sequentially reading out the image format from the RAM 13, transferring the image format to the VRAM 18, and the CRT controller 19 outputting the data on the VRAM 18.

At P3, one menu is selected by the operator from the main menu displayed at P2.

That is, in FIG. 8, menus 1 to 5 are displayed, and first to fifth buttons 3 corresponding to the respective numbers are displayed.
There are 6,37,38,39,40. The mouse cursor 35 is moved on the screen by operating the mouse 11, and by pressing the mouse switch 11a, the position of the mouse cursor 35 on the screen at that time is specified. That is, by moving the mouse cursor 35 on the first to fifth buttons 36, 37, 38, 39, 40 and pressing the mouse switch 11a there, the menu corresponding to the button is selected.

When the mouse cursor 35 is moved to the display position of each menu and the mouse switch 11a is pressed there, the selected marker 31 is displayed so as to surround the menu, and the mouse switch 11a is pressed again inside the selected marker 31. Menu selection is also possible.

The screen display and menu or command selection using the mouse 11 are almost the same in other screens.
Hereafter, it is omitted.

In FIG. 7, at P4, it is determined whether or not the selected menu is "1".
Move to P6.

In P6, it is determined whether or not the selected menu is "2". If "2", the process proceeds to P7, and if not, the process proceeds to P8.

In P8, it is determined whether or not the selected menu is "3". If "3", the process proceeds to P9, and if not, the process proceeds to P10.

In P10, it is determined whether or not the selected menu is "4". If "4", the process proceeds to P11; otherwise, the selected menu is regarded as "5", that is, the end, and
Quit the program.

 At P5, an endoscope inspection process is performed.

FIG. 10 shows a flowchart of a subroutine for endoscopy.

In FIG. 10, in P12, various data are initialized, and a "record mode set" command is sent to the video disk recorder device 6, and then a track number is obtained by a "track number check" command. .

At P13, it waits for reception of data from the video processor device 4.

In P14, it is determined whether or not the transmitted data is "release". If "release", the process proceeds to P15, and if not, the process proceeds to P16.

At P15, it is determined whether or not release is possible. That is, if either the patient ID has already been entered, or both the patient's name and date of birth have been entered, release is possible and the process proceeds to P7 in other cases.

The patient ID, the patient's name, and the date of birth are specific information.

In P16, a command of “still image recording” is sent to the video disk recorder device 6.

In P17, a message stating that release is not possible is output.

In P18, it is determined whether or not the data received in P13 is a patient ID. If the data is a patient ID, the process proceeds to P19, and if not, the process proceeds to P24.

In P19, it is determined whether or not the inspection is currently being performed. That is, if the image has already been recorded and the registration of the image in the database has not been performed yet, it is determined that the image is being inspected, and the process proceeds to P20.

At P20, newly registered images are registered in the database. In other words, a "track number check" command is sent to the video disk recorder device 6 to obtain a track number, and the track number obtained in P12 together with related data is recorded at the end of the inspection data file as a recording start position number, The track numbers obtained here are additionally recorded as recording end position numbers. If the patient is not registered in the patient data file, the patient is also registered there. If the patient ID has not been input, the number following the patient ID at the end of the patient data file is automatically given.

At P21, various data other than the data determined as the patient ID at P18 are cleared.

At P22, a patient data file is searched based on the patient ID.

In P23, the patient data retrieved in P22 is transmitted to the video processor 4.

In P24, it is determined whether the data received in P13 is "Name", "Date of birth", or "Gender". If any of them is applicable, proceed to P25, otherwise proceed to P27 .

At P25, it is determined whether or not the transmitted data is acceptable. That is, if the patient ID has not been entered yet,
Even if it has already been entered, if it has not been registered in the patient data file, the process proceeds to P26 as accepting, and otherwise returns to P13 without doing anything.

In P26, data is set and held. That is, when registration in the database is performed from this state, the data set here is recorded.

In P27, it is determined whether or not the data received in P13 is "test completed". If "data has been finished", the process returns to P28, and if not, the process returns to P13.

In P28, it is determined whether or not the inspection is currently being performed. That is, if the image recording has already been performed and the registration of the image in the database has not been performed yet, it is considered that the inspection is being performed, and the process proceeds to P29.

 In P29, the same processing as in P20 is performed.

In P30, the subroutine ends, and the routine returns to the called routine. The flow from P12 to P30 constitutes the related information search means 52.

Returning to FIG. 7, P7 performs an image search process. In the image search, an operator inputs a keyword, calls an examination corresponding to the keyword, and displays an image recorded in the examination.

 P9 performs processing of patient data management.

In the patient data management, the contents of the patient data file shown in FIG. 6A are edited. That is, registration of a new patient, that is, addition of data to a patient data file or modification of existing patient data, etc., is performed by a user operation.

 P11 is an optical disk management process.

In optical disk management, check whether the optical disk has been registered, if it has been registered, check the disk number, display a list of the already registered disks and the number of recorded images, and create a new disk Perform registration, etc.

 Next, the operation of the embodiment will be described.

If the program is started in FIG. 7, the processing of the system is performed at P1, and then the main menu of FIG. 8 is displayed on the computer display 9 at P2.

Here, when "1" is input, the processing of the endoscope inspection is executed.

At this time, the light source device 2 emits illumination light based on a timing signal from the video processor device 4, and the illumination light is emitted from the illumination lens 1e through the ride guide 1d toward the observation site. The illuminated image of the observation site is formed on the solid-state imaging device 1g by the objective lens 1f, and is converted into an electric signal by the solid-state imaging device 1g driven by a drive signal from the synchronization signal generation circuit 61 of the video processor device 4, This electric signal is converted into a video signal by the image processing unit 62 of the video processor device 4. The converted video signal is output to the first TV monitor 3 via the superimposing unit 63, and is displayed on the monitor-added endoscope display unit 3a shown in FIG. Is output.

At this time, the host computer 8 operates based on FIG.

When the operator inputs a patient ID from the first keyboard 5, the processing is performed in the order of P18, P19, P22, and P23, and data relating to the patient is sent to the video processor device 4 and the first processing is performed.
Displayed on TV Monuta 3. After this, if the operator operates the release switch 1a, the image is recorded at P14, P15, P16, and if "Examination end" is input, registration to the database is performed at P27, P28, P29 and the inspection is completed. .

If the patient ID has not been registered, nothing is transmitted in P23.Instead, if the operator inputs other data, the processing is performed in P24, P25, and P26. It is registered in the data file and the inspection data file.

If the patient's name and date of birth are entered without entering the patient ID, the examination can be performed, and at the end of the examination, those data are registered in the patient data file and the examination data file together with the automatically generated patient ID. Is done.

If the patient ID is entered once and it is already registered in the patient data file, even if the operator later enters other related data, it will be ignored and registered in the processing of P24 and P25. Is finally recorded in the database.

At the end of the inspection, the operator does not enter
When the patient ID is rewritten, it is automatically regarded as the end of the examination, and the contents up to that point are registered in the database in the processing of P18, P19, P20, P21, and thereafter, it is assumed that other new examinations are performed. Process.

Once the inspection is completed and the end of the inspection is input again, P2
7, the process of “endoscopy” is completed in P28 and P30, and the process returns to P2 in FIG.

Returning to FIG. 7, if the "patient data management" command is selected in P3, the patient data management process in P9 is performed. Here, data of a new patient is input prior to the examination, and data correction is performed when there is an error in the already input data.

Also, if you select the command “Optical Disk Management”, P1
An optical disk management process is performed, and a new disk is registered.

In this embodiment, at the start of the endoscopy, the operator
Other data is automatically set just by inputting the ID, which is very convenient, and the possibility of erroneous data being input is reduced. In addition, a new patient whose patient ID has not yet been registered can be tested by entering the patient's name and date of birth, and at the end of the test, the patient ID is automatically given. It can be carried out.

In the process shown in FIG. 10, the registration in the database is performed at the end of the inspection, but the registration may be performed each time the release is performed. In this case, even if a power failure occurs during the inspection, it does not occur that the data is registered in the optical disk but not registered in the database.

FIG. 6 shows the contents as an examination data file, a patient data file, and a disc data file,
These were used on each display screen, etc., but the contents are not only shown here, but also as patient data, such as the patient's disease name, presence or absence of allergies, patient family data, physical data such as height and weight, etc. In addition, as examination data, a database is created by associating various data such as an examiner, examination start time, examination required time, presence or absence of a biopsy, examination results, and these can be input and edited, and associated with an appropriate screen. It can also be displayed and referenced.

Further, the age of the patient at the time when the examination was performed may be entered in the examination data file. The patient's age can be calculated from the date of birth and the date of examination, and can be automatically calculated and registered at the time of registration of the date of birth and for each test after registration.

Further, P19 and P28 in FIG. 10 may be changed so that even if there is no recorded image, it can be registered as inspection data. In this case, for example, when such a system is newly introduced, by registering the examination before the introduction without an image, data on patients who are continuously consulted can be managed collectively.

FIG. 11 is an explanatory diagram of the configuration of an image file system according to the second embodiment of the present invention.

This embodiment is an image file system using a conventional fiberscope instead of an electronic scope. Unlike the first embodiment, there is no electronic scope device 1, video processor device 4, and first keyboard 5, but instead a fiberscope. A device 25, a camera head 26, a camera control unit (CCU) 27, and a spur impose device 28 are connected,
The light source device 29 is also different.

25, a camera head 26, a CCU 27, a light source device 29, a first TV monitor 3 and a second keyboard 10, and the image reproducing device 43 includes a superimposing device 28,
Video disk recorder device 6 and second TV monitor 7
, A host computer 8, a computer display 9, and a mouse 11.

In this embodiment, the release signal is the release switch 25a.
Is transmitted to the host computer 8 via the light source device 29, and the image is captured by the camera head 26.
The video signal is converted into a video signal by the CCU 27, and a screen substantially similar to the screen shown in FIG. 7 is output by the superimposing device 28 as a synthesizing means. At this time, input of data and the like is performed by the second keyboard 10.

 Other configurations are the same as in the first embodiment.

In this embodiment, a fiber scope that has been widely used can be used, so that various types of scopes can be connected, and the operator can select and use a scope more suitable for inspection.

Further, it may be possible to select whether or not to superimpose with this system. In this case, when the superimposition is not performed, not only the endoscope image but also various images such as an ultrasound endoscope image related to the endoscope, an image of a patient's face, an X-ray image, etc. Can be managed together.

[Effects of the Invention] As described above, according to the present invention, the provision of the related information search means for searching for information related to the specific information input from the specific information input means allows an erroneous operation at the time of data input. Endoscopy can be started immediately without performing an endoscopy.
