The monitor 15 is connected to the video processor 14 and displays images. The keyboard 16 is connected to the video processor 14 and performs manipulation inputs on the video processor 14. The signal transmission cable 17 is used for transmitting image signals and different kinds of data between the electronic endoscope 12 and the light source device 13 and the video processor 14.

The electronic endoscope 12 includes an endoscope imaging unit, whose long and narrow inserting portion is inserted to a subject part of a body cavity, for example, of a patient 11 for the observation. The electronic endoscope 12 supplies to the video processor 14 the image, that is, endoscope image signals of the subject part imaged by the endoscope imaging unit. The video processor 14 creates video signals by performing video signal processing on the endoscope image signals from the endoscope 12 and displays the image on the monitor 15. The endoscope image signals from the electronic endoscope 12 are output to the image filing device 2 through the signal transmission cable 10. In addition, the video processor 14 sends/receives different kinds of data to/from the image filing device 2 through the signal transmission cable 10.

The image filing device 2 includes a personal computer 21, a monitor 22, a keyboard 23 and a mouse 24.

The personal computer 21 receives manipulation inputs from the keyboard 23 and the mouse 24 and video signals are supplied from the endoscope device 1 through the signal transmission cable 10. The personal computer 21 sends/receives different kinds of data to/from the endoscope device 1 through the signal transmission cable 10.

The personal computer 21 records image signals output from the endoscope device 1 associated with examination information regarding an endoscope examination input by using the keyboard 23 and/or the mouse 24 in accordance with a release trigger generated by pressing an endoscope switch, such as a release switch, provided in the-electronic endoscope 12. In addition, the personal computer 21 displays image signals and/or information output from the endoscope device on the monitor 22.

Thus, the image filing device 2 records image signals output from the endoscope device 1 and associated with examination information regarding the input endoscope examination in accordance with the release trigger.

The internal construction of the personal computer 21, which is a main part of the image filing device 2, will be described with reference to FIG. 2.

The personal computer 21 includes a CPU 21a, a ROM 21b, a RAM 21c, a VRAM 21d, a hard disk 21e, a hard disk 21e, an SCSI interface portion 21f, a mouse interface portion 21g, a keyboard interface portion 21h, a communication interface portion 21i in the RS232C format, a video circuit 21j, an A/D converting portion 21k, and an image memory 211.

The CPU 21a is a main control unit, which controls different parts of the personal computer 21. The ROM 21b stores programs operating the CPU 21a, messages displayed on the monitor 22 and so on. The RAM 21c is used as a work area for the CPU 21a and a temporally memory area for different kinds of data. The VRAM 21d temporarily stores image data to be output to the monitor 22.

The hard disk 21e stores image data and different kinds of data. The SCSI interface portion 21f sends/receives data in the publicly known SCSI format to/from hard disk 21e.

The mouse interface 21g detects an input from the mouse 24. The keyboard interface portion 21h detects an input from the keyboard 23. The communication interface portion 21i is an interface in the publicly known RS232C format and sends/receives different kinds of data to/from the endoscope device 1.

The video circuit 21j is an interface circuit, which inputs image signals output from the endoscope device 1. The A/D converting portion 21k A/D converts image signals input by the video circuit 21j. The image memory 211 temporarily stores image data output from the A/D converting portion 21k.

In this case, the hard disk 21e is used as an endoscope examination information recording unit, which records examination information regarding an endoscope examination.

The keyboard 23 and the mouse 24 are search condition input units, which are used for inputting a search condition to search the examination information.

The CPU21a, the ROM 21b and the RAM 21c function as endoscope examination information searching units, which are used for searching the examination information recorded by the endoscope examination information recording unit in accordance with the input search condition.

In addition, the CPU 21a, the ROM 21b, and the RAM 21c function as a before/after search setting unit, which are used for setting the before/after search condition in order to change a search range in accordance with a predetermined condition with respect to the search condition.

Furthermore, the CPU 21a, ROM 21b and the RAM 21c function as a before/after executing unit, which are used for searching the examination information recorded by the endoscope examination information recording unit in accordance with the before/after search condition set by the before/after search setting unit.

The monitor 22 and the VRAM 21d function as examination information display unit, which is used for displaying at least one of the search results by the endoscope examination information searching unit and the before/after search executing unit.

Additionally, the keyboard 23 and the mouse 24 function as a before/after search selecting unit, which is used for selecting a search by the before/after search executing unit. The before/after search executing unit searches the examination information in accordance with the selection by the before/after search selecting unit.

In this way, the image filing device 2 having the personal computer 21 as the main part can display image data obtained by the endoscope device 1 on the monitor 22 and can store them in the hard disk 21e.

In order to perform processing in the image filing device 2, an operator inputs data and/or an instruction by using the keyboard 23 and/or the mouse 24 in accordance with different kinds of screens displayed on the monitor 22. Then, the CPU 21a controls parts corresponding to the input data and/or instruction. In other words, the image filing device 2 performs different kinds of processing in accordance with the flow in the screen displayed on the monitor 22.

An outline of the screen construction of the image filing device 2 will be described with reference to FIG. 3.

First of all, when the image filing device 2 is started, a log-in screen 31 is displayed in which an operator is authenticated.

The image filing device 2 displays a scheduler screen 41 in which a list of examination schedules are displayed when the operator is authenticated in the log-in screen 31.

The scheduler screen 41 can call up an examination information editing screen 61 where patient information can be edited.

The scheduler screen 41 can call up an examination executing screen 71 where an examination is executed by connecting to the endoscope device 1 and images can be captured from the endoscope device 1.

The scheduler screen 41 can call up an image selecting screen 81 where an image among captured images is selected for the examination report to be created.

In addition, the scheduler screen 41 can call up a report creating screen 91, which is a screen where the examination report can be created.

Furthermore, the scheduler screen 41 can call up a implementation information input screen 101 where a diagnosis code, an accounting code and so on relating to the examination can be input and be checked.

An example of an entire flow of an operation on the image filing device 2 will be described with reference to FIG. 4. Notably, reference numerals S1 to S8 in FIG. 4 are given to processing steps.

First of all, an operator starts the endoscope image filing device 2. Then, the endoscope image filing device 2 displays a log-in screen 31 on the monitor 22. Under this condition, the operator performs manipulations such as a password input by using the keyboard 23 and/or mouse 24. Here, the personal computer 21 authenticates the operator, and, at a step S1, the operator logs in. Thus, the endoscope image filing device 2 displays the scheduler screen 41 on the monitor 22. Here, at a step S2, the operator checks the examination schedule.

Next, at a step S3, when the examined patient is a new patient, the operator calls up the patient list screen 51 and the patient information editing screen 52 and registers the patient information by using the keyboard 23 and/or the mouse 24.

Next, at a step S4, the operator calls up the examination information editing screen 61 and inputs a new examination reservation.

Next, at a step S5, the operator calls up the examination executing screen 71 and executes an examination by using the endoscope device 1 connected to the image filing device 2. The images obtained by the endoscope device 1 are stored in the image filing device 2.

Next, at a step S6, the operator calls up the image selecting screen 81 and selects an image, among the images in the examination execution, referred in the examination report to be created.

Next, at a step S7, the operator calls up the report creating screen 91 and creates the examination report.

Next, at a step S8, the operator calls up the implementation information input screen 101 and inputs the diagnosis code, the accounting code and so on relating to the examination.

The above-described flow is the example of the entire flow of the operation.

The more detail construction and operations for respective screens will be described below.

FIG. 5 is a screen display example of the scheduler screen 41.

In the scheduler screen 41, an examination information list display area 41b is located for displaying a list of examination information.

One piece of examination information is called “examination information record” herein.

The first line of the examination information display area 41b displays headings corresponding to data items included in an examination information record.

The examination information record is displayed from the third row of the examination information list display area 41b. One examination information record is displayed in one row of the examination information list display area 41b.

The data items included in the examination information record include an examination date 41ba, a starting time 41bb, an ending time 41bc, the last name of the patient 41bd and the first name of the patient 41be for the examination, an examiner name 41bf, a name 41bg of a used examination room and so on.

An examination status display field group 41c for displaying a status, such as a progress, of works relating to the examination is located in the examination information display area 41b.

An examination status display field 41ca included in the examination status display field 41c displays a distinction indicating whether or not the input required items of examination information and the input required items of the information regarding the patient to be examined have been input. For example, when the input required items of the examination information and the input required items of the information regarding the patient to be examined have been all input, “x” is displayed in the examination status display field 41ca. Otherwise, the examination status display field 41ca is left empty.

The examination status display field 41bc displays a distinction indicating whether or not the data when a written agreement for the examination is received from the patient is input. For example, when the date when the written agreement of the examination is received from the patient has been already input, “x” is displayed in the examination status display field 41cb. Otherwise, the examination status display field 41cb is left empty. The examination status display field 41cc displays a distinction indicating whether or not images of the examination have been recorded. For example, when the examination has been already executed, the number of images recorded in the examination is displayed in the examination status display field 41cc. When the examination has not been executed, the examination status display field 41cc is left empty. In other words, a number displayed in the examination status display field 41cc means that images of the subject part of the patient have been obtained by the examination.

The display status display field 41cd displays a distinction indicating whether or not an examination report has been created. For example, when the examination report has been created, the “x” is displayed in the examination status display field 41cd. When the examination report has not been created yet, the examination status display field 41cd is left empty.

The examination status display field 41ce displays a distinction indicating whether or not an accounting code has been input. When the accounting code has been input already, “x” is displayed in the examination status display field 41ce. When the accounting code has been input but some change occurs therein, “!” is displayed in the examination status display field 41ce. When the accounting code has been input but the applicable data is not present, “o” is displayed in the examination status display field 41ce. When the accounting code has not been input yet, the examination status display field 41ce is left empty.

The examination status display field 41cf displays a distinction indicating a result status of a living body examination, for which a living body organization is taken in the endoscope examination. For example, when the living body examination has been implemented and the examination result has been already obtained, “x” is displayed in the examination status display field 41cf. When living body examination has been performed but the examination result has not been obtained yet, “!” is displayed in the examination status display field 41cf. When the endoscope examination has been implemented but the living body examination has not been implemented, “o” is displayed in the examination status display field 41cf. When the endoscope examination has not been implemented yet, the examination status display field 41cf is left empty.

The examination information list display area 41b can not only display all of the examination information records but also display interested examination information records specifically.

Positions of data items in the first row, that is, in a row where item names of data items are displayed are provided with a filter button group 41d to be used for calling up a screen on which a narrowing-down condition can be set in each of the data items.

Each in the filter button group 41d is at the convex state when no narrowing-down condition is specified in the corresponding data item.

The button at the convex state is a button under a condition where a shade is displayed so that the button can appear isolated on the screen. On the other hand, a button at the concave state is a button under a condition where a shade is displayed so that the button can appear concave on the screen.

Here, the operator clicks a convex button in the filter button group 41d by using the mouse 24. Then, the image filing device 2 opens a narrowing-down condition setting screen, which will be described later, for setting a narrowing-down condition in the corresponding data item. Here, the operator inputs a narrowing-down condition so that only the examination information record, which can satisfy the narrowing-down condition, can be displayed in the examination information list display area 41b.

Each in the filter button group 41d becomes concave when the button corresponds to the data item for which the narrowing-down condition is set.

When there are multiple concave buttons in the filter button group 41d, examination information records are narrowed down by applying AND to the narrowing-down conditions specified in each of the filter button group 41d. Then, the specific examination information records are displayed in one row of the examination information list display area 41b.

Here, the operator clicks a concave button of the filter button group 41d. Then, the narrowing-down condition, which is specified for the corresponding data item, is released. Then, the button of the filter button group 41d becomes convex.

Here, a flow of operations performed when a narrowing-down condition is specified for the examination date 41ba, for example, will be described.

An operator clicks a filter button 41da at a position corresponding to the examination date 41ba by using the mouse 24. Then, the image filing device 2 calls up a narrowing-down condition setting screen 42 shown in FIG. 6, which is used for setting a narrowing-down condition in the examination date 41ba.

On the narrowing-down condition setting screen 42, the operator specifies dates in a setting field 42a for a narrowing-down start date and a setting filed 42b for a narrowing-down end date, respectively.

Then, the narrowing-down condition setting screen 42 is closed and the filter button 41da becomes concave. Then, only the examination information records between the dates specified in the setting fields 42a and 42b are displayed in the examination dates 41ba in the examination information list display area 41b.

When the operator inputs either one of the current date, the first date of the current month, the first date of the current week and the first date of the current year is input in each of the setting fields 42a and 42b, one of a button group 42d corresponding to the items can be clicked and selected by using the mouse 24. In addition, the number of dates with respect to the current date can be set in each of the setting fields 42a and 42b. In this case, the operator can click a button 42e corresponding to the item by using the mouse 24. Then, the number of relative dates can be set by clicking a button 42f and a button 42g, which increases and decreases one day each, respectively, by using the mouse 24. Furthermore, the operator can input the year, the month and/or the day in an input field 42h by using the keyboard 23.

The operator can click a calendar-calling button 42i by using the mouse 24 so that a calendar screen 43 shown in FIG. 7 can be called up. In this case, when a date button 43a displayed on the calendar screen 43 is clicked so that a date corresponding to the date button 43a can be input in the input field 42h so as to set the date.

The year and the month to be displayed on the calendar screen 43 can be changed by using the mouse 24. Thus, any desired year, month and/or day can be selected.

When the operator clicks a filter button 41dd corresponding to the last-name position 41bd, for example in the examination information list display area 41b shown in FIG. 5, a narrowing-down condition setting screen 44 shown in FIG. 8 is called up for setting a condition of patient's last name to be narrowed down.

The operator can input patient's last name in an input field 44a on the narrowing-down condition setting screen 44b by using the keyboard 23 and click an OK button 44b. Then, the image filing device 2 displays only the examination information record corresponding to the patient having the input last name in the examination information list display area 41b. Notably, in order to narrow down the condition for patient's last name, last names completely matching with the input string may be searched in the input field 44a. Alternatively, last names including the string can be searched.

Furthermore, the operator can click, for example, filter button 41ec corresponding to the examination status display field 41cc indicating whether or not the examination has been finished in the examination information list display area 41b shown in FIG. 5 by using the mouse 24. Then, the image filing device 2 calls up a narrowing-down condition setting screen 45, as shown in FIG. 9, which is used for setting to use the distinction indicating whether or not the examination has been done or not as a narrowing-down condition.

The operator clicks and selects either one of distinctions indicating the examination has been done and has not been done, respectively, in the setting field 45a of the narrowing-down condition setting screen 45 and clicks an OK button 45b. Then, the image filing device 2 displays, in the examination information list display area 41b, only the examination information records each having the status in the examination status display field 41 cc matching with the setting in the setting field 45a.

In the examination information list display area 41b shown in FIG. 5, the operator may click, for example, a filter button 41ee corresponding to the examination status display field 41ce indicating a distinction regarding the accounting code. Then, the image filing device 2 calls up a narrowing-down condition setting screen 46, as shown in FIG. 10, for setting to use, as a narrowing-down condition, the distinction indicating whether or not the accounting code has been input. The operator clicks and selects a distinction indicating the status of the accounting code input in the setting field 46a on the narrowing-down condition setting screen 46 and clicks an OK button 46b by using the mouse 24. Then, the image filing device 2 displays, in the examination information list display area 41b, only the examination information record having the examination status display field 41ce matching with the setting field 46a.

Next, a flow of the execution of before/after searches for the examination information list display will be described with reference to a flowchart shown in FIG. 11. Reference numerals S21 to S45 in FIG. 11 are given to processing steps.

The personal computer 21 authenticates an operator. Then, at the step S1 in FIG. 4, the operator logs in, and the scheduler screen 41 is called up in the monitor 22. Then, the personal computer 21 starts to display the examination information list at a step S21 in FIG. 11.

Once the personal computer 21 starts to display the examination information list, examination information is searched in accordance with an initial narrowing-down condition and displays a corresponding examination record in the examination information list display area 41b at a step S22.

Next, the personal computer 21 waits for a button input on the scheduler screen at a step S23.

When a button input is performed by manipulating, for example, the mouse 24 at a step S23, the personal computer 21 checks whether or not the input button is a date before/after button 41j at a step S24.

When the input is not through the date before/after button 41j at the step S24, the personal computer 21 checks whether or not the input button is an end button or not at a step S25. If the input button is the end button, the personal computer 21 performs end processing at a step S44. Then, the execution of the before/after search ends at a step S45. In other words, the schedule display screen is closed.

If the input button is not the end button at the step S25, the personal computer 21 performs processing in accordance with the input button at a step S26. Then, the processing returns to the step S23. At the step S26, the personal computer 21 searches examination information in accordance with the search condition input by using the input button. Then, the personal computer 21 performs processing such as displaying the corresponding examination record in the examination information list display area 41b.

If the input is through the date before/after button 41j at the step S24, the personal computer 21 obtains, at a step S27, information specified by the filter button 41da used for the search through the examination list displayed in the examination list display area 41b currently, that is, information regarding the start date and the end date for the narrowing-down.

Next, the personal computer 21 checks whether the input button is the before search button 41ja or the after search button 41jb.

If the input button is the before search button 41ja at a step S28, the personal computer 21 checks whether or not the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is set in years at a step S29.

If the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is set in years at the step S29, the personal computer 21 sets the narrowing-down start date and the narrowing-down end date so as to obtain information one year ago set by the filter button 41da at a step S30.

If the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is not set in years at the step S29, the personal computer 21 checks whether or not the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is set in months at a step S31.

If the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is set in months at the step S31, the personal computer 21 sets the narrowing-down start date and the narrowing-down end date so as to obtain information one month ago set by the filter button 41da at a step S32.

If the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is not set in months at the step S31, the personal computer 21 checks whether or not the information regarding the narrowing-down start date and the narrowing-down end date obtained at the step S27 is set in weeks at a step S33.
