Description

  The present invention relates to a medical device having a screen lock function and a screen lock control program.

  In recent years, the necessity of information security management has been increasing, and various security management techniques have been developed. For example, a screen lock function has attracted attention as one of security management techniques for accessing data stored in a computer.

  The screen lock function is a technology that works when the computer operation is interrupted and locks the computer display screen to prevent operations from being accepted and to prevent leakage of display information. Yes (see, for example, Patent Document 1). This screen lock function is activated when an operation such as a key input or a mouse operation is not performed for a certain period of time or when a predetermined operation is performed.

  In the medical field, information security management technology is being developed mainly from the viewpoint of protecting personal information of patients, and medical devices equipped with a screen lock function are also being studied. There are a wide variety of medical devices to be targeted. For example, diagnostic imaging apparatuses such as ultrasonic diagnostic apparatuses, X-ray CT (Computed Tomography) apparatuses, X-ray diagnostic apparatuses, magnetic resonance imaging (MRI) apparatuses, nuclear medical diagnostic apparatuses, and hospital information systems (HIS: Medical information systems such as a hospital information system (RIS), a radiology information system (RIS), and a medical image storage and communication system (PACS) are assumed.

In addition, if examination results, diagnosis results, etc. are changed, it may lead to misdiagnosis. Furthermore, leakage of information such as the patient's past history and current medical condition may seriously threaten the patient's privacy.

  In addition, background processing may be performed in a state where the display screen is screen-locked. Even if an error occurs in the background process in this state, the screen lock state is maintained, and the user cannot recognize the occurrence of the error until the screen lock is released. Further, even if a dialog display request is made in the background processing, the dialog is not displayed on the display screen. Therefore, the content of the dialog cannot be confirmed until the screen lock is released. When such a situation occurs, a large loss of time occurs, and in some cases, it cannot be said that there is no danger to the patient. Further, even when an abnormal operation occurs in the hardware when the screen is locked, the user cannot recognize that fact.

  Considering such circumstances, it seems appropriate to unconditionally release the screen lock when an error occurs, when a dialog display is requested, or when an abnormal operation occurs. However, in view of the circumstances peculiar to the medical field described above, it is clear that unconditional release of the screen lock involves a great risk. Thus, in order to apply the screen lock function to the medical device in an effective form, the user can recognize the operation status of the device such as the background processing status without unconditionally releasing the screen lock.

  FIG. 3 shows an example of registration information 430. In the registration information 430 shown in the figure, as “operation status”, “normal” indicating normal operation, “dialog display” indicating occurrence of a dialog display request, “warning” indicating occurrence of a warning, level "Error (level 1)" indicating the occurrence of an error of level 1, "Error (level 2)" indicating the occurrence of an error of level 2, "Error (level 3)" indicating the occurrence of an error of level 3, “Information display” indicating the generation of a display request for information such as medical information is set. In addition, the operation status which can be set is not limited to these, For example, the operation status according to the operation | movement form etc. of the medical apparatus 1 can be set suitably.

  Here, a specific example of error level classification will be described. An X-ray CT apparatus is used as the medical apparatus 1. As a level 1 error, a minor error such as an error in writing a captured CT image to a medium is assigned. As the level 2 error, a moderate error such as a storage error of raw data collected by the gantry and a storage error of reconstructed data is assigned. In addition, as a level 3 error, an error when scanning a patient, for example, when the X-ray exposure dose is different from the set value (when the exposure dose is excessive or not) Severe errors that are dangerous to the patient are assigned. Further, when the value detected by the weight detection sensor 34 changes during the scan (for example, when the patient gets off the bed 33 or when the patient moves greatly), for example, an error of level 2 or level 3 occurs. Can be set to

  In the registration information 430, setting information of “unlock”, “screen ID”, “switching”, “user notification”, “notification destination information”, and “message” is recorded for each of the above operation situations. ing. Each of these setting information is recorded in association with the corresponding operation status. This association can be performed by, for example, operation status identification information described later.

  In the setting information “unlock” column, whether the screen lock is automatically released when the operation status is reached, that is, whether the screen lock screen is displayed (not released) or the screen is displayed. Information specified about whether to return to a normal screen (such as a normal inspection screen or a diagnostic screen that can accept an operation) without displaying the lock screen is recorded.

  In the setting information “unlock” column of FIG. 3, a check box is provided for each operation status. A filled check box indicates that the screen lock is set to be released, and an unfilled check box indicates that the screen lock is not set to be released (the same applies hereinafter). . Therefore, in the registration information 430 in FIG. 3, the screen lock is released only in the case of the operation status “error (level 3)”.

  In practice, a filled check box corresponds to a state in which a predetermined flag is set, and an unfilled check box corresponds to a state in which the flag is not set.

  In the setting information “screen ID” field, a screen ID (screen identification information) assigned to the screen lock screen displayed when the operation status is reached is recorded. Note that when the screen lock screen is not displayed even when the operation status is reached (when “unlock” is on), it is not necessary to record the screen ID.

  In the column of setting information “screen ID” of the registration information 430 in FIG. 3, “normal” is associated with the screen ID “lock_pic — 1” of the screen lock screen 421 shown in FIG. The “dialog display” is associated with the screen ID “lock_pic — 2” of the screen lock screen 422 shown in FIG. The “warning” is associated with the screen ID “lock_pic — 3” of the screen lock screen 423 shown in FIG. The screen ID “lock_pic_4” of the screen lock screen 424 shown in FIG. 2D is associated with “error (level 1)”. “Error (level 2)” is associated with the screen ID “lock_pic_5” of the screen lock screen 425 shown in FIG. The screen error of the screen lock screen is not associated with “error (level 3)”. A screen ID “lock_pic_6” of a screen lock screen (not shown) is associated with “information display”.

  The association between the operation status and the screen lock screen is not the use of such a screen ID, but the storage location information (directory) of the screen lock screen in the screen storage unit 42 and the folder name of the folder storing the screen lock screen. Etc. can be used.

  In the setting information “switch” column, information designated as to whether or not to switch the display to the screen lock screen specified by the screen ID when the operation status is reached is recorded. In the registration information 430 of FIG. 3, “normal”, “dialog display”, “warning”, “error (level 1)”, and “error (level 2)” are switched to the corresponding screen lock screens, respectively. The “error (level 3)” and “information display” are set so as not to be switched.

  In the setting information “user notification” column, information designated as to whether or not to notify the user (user terminal 10) that the operation status has been reached is recorded. In the registration information 430 of FIG. 3, “normal”, “dialog display”, “warning”, “error (level 1)”, and “information display” are not notified to the user terminal 10, respectively. “Error (level 2)” and “error (level 3)” are set to be notified.

  Address information of the user terminal 10 is recorded in the setting information “notification destination information” column. When a mobile phone or a fixed phone is used as the user terminal 10, the phone number is recorded as address information. Further, when a mobile phone, PDA, or personal computer having an electronic mail function is used as the user terminal 10, the electronic mail address is recorded as address information. In the registration information 430 of FIG. 3, the telephone number “0287-XXXX-XXXX” is recorded for “error (level 2)”, and the e-mail address “Tsb @ xxx.” Is recorded for “error (level 3)”. xxx.jp "is recorded.

  In the setting information “message” column, the message content notified to the user terminal 10 is recorded. In the registration information 430 of FIG. 3, the message “level 2 error has occurred” is recorded for “error (level 2)”, and the message “level 3 error” is recorded for “error (level 3)”. Has occurred "is recorded.

  Since “notification destination information” in the case of “error (level 2)” is a telephone number, the message “level 2 error has occurred” is regarded as voice information. In addition, since “notification destination information” in the case of “error (level 3)” is an e-mail address, the message “level 3 error has occurred” is regarded as character information.

  These pieces of information recorded in the “message” column are for informing the user of the occurrence of a predetermined operation situation, and correspond to an example of “notification information” of the present invention.

(Information Registration Department)
As described above, the user performs new registration, deletion, change, and the like of the screen lock screen by operating the operation unit 31. Similarly, by operating the operation unit 31, new registration, deletion, and change of each information included in the registration information 430 are performed.

  When the user inputs a new screen lock screen, the information registration unit 41 receives a signal from the operation unit 31 and causes the screen storage unit 42 to store the image data of the new screen lock screen. When the user requests to delete the screen lock screen stored in the screen storage unit 42, the information registration unit 41 receives the signal from the operation unit 31 and displays the screen lock screen requested to be deleted on the screen storage unit.

When the user requests to change the screen lock screen stored in the screen storage unit 42, the information registration unit 41 receives the signal from the operation unit 31 and changes the screen lock screen requested to be changed. . New registration, deletion, and change of the registration information 430 are performed in the same manner.

  The information registration unit 41 includes a microprocessor such as a CPU that executes a screen lock control program (not shown) and a memory such as a RAM.

(Device monitoring unit)
The apparatus monitoring unit 44 monitors the operation status of each unit of the hardware configuration unit 3 by receiving a signal indicating the operation status from the hardware 32 of the hardware configuration unit 3, the bed 33, or the like. Further, the device monitoring unit 44 receives a signal indicating a detection result from the weight detection sensor 34. The device monitoring unit 44 also monitors the operation status of the application execution unit 2 by receiving a signal indicating the processing status of the arithmetic processing and control processing executed by the application execution unit 2 based on the application software.

  The device monitoring unit 44 stores information (operation status identification information) for identifying various operation statuses designated in advance. For example, in this embodiment, log character string information corresponding to dialog display, log character string information when a warning occurs, log character string information corresponding to processing corresponding to each level error, information display The character string information of the log corresponding to is stored as the operation status identification information. Information for identifying signals from the application execution unit 2 and the hardware configuration unit 3 is also stored as operation status identification information.

  The device monitoring unit 44 recognizes a log or signal generated when such processing or operation occurs, and determines whether the log or signal matches any of the operation status identification information. If they match, the device monitoring unit 44 determines that the operation status has occurred, and inputs an operation status generation signal indicating that to the control unit 46. This operation status generation signal is added with the operation status identification information of the operation status determined to have occurred.

  The device monitoring unit 44 acting in this way corresponds to an example of the “operation status monitoring unit” of the present invention. For example, a microprocessor such as a CPU that executes the screen lock control program described above and a memory such as a RAM And a non-volatile storage device such as a hard disk drive for storing operation status identification information.

(Timekeeping Department)
The timekeeping unit 45 is constituted by a microprocessor such as a CPU having a function of measuring the current time (year, month, day, hour, minute, second, etc.).

(Control part)
The control unit 46 performs operation control of each part of the medical device 1 including control of display processing by the display unit 35. The control unit 46 also controls the communication unit 5 to perform message notification processing for the user terminal 10. Specific operation modes of the control unit 46 will be described later.

  In particular, the control unit 46 performs display control of the screen lock screen by the display unit 35. When the screen lock screen is displayed, the control unit 46 does not accept an operation signal from the operation unit 31 (that is, does not execute processing corresponding to the operation signal), and when the screen lock screen is not displayed ( When a normal screen is displayed), an operation signal is received.

  The control unit 46 corresponds to an example of the “control unit” of the present invention, and includes, for example, a microprocessor such as a CPU that executes the screen lock control program described above and a memory such as a RAM. The In addition, the “notification means” of the present invention includes, for example, the control unit 46 and the communication unit 5.

[Communication Department]
The communication unit 5 includes a communication interface such as a modem or a LAN card for performing data communication via the network N. The communication unit 4 performs data communication under the control of the device control unit 4 (control unit 46).

[Mode of operation]
The operation mode of the medical device 1 of the present embodiment configured as described above will be described. First, it demonstrates, referring FIG. 4 which shows an example of the basic operation | movement aspect of the medical apparatus 1. FIG. The flowchart of FIG. 4 represents processing when a predetermined operation situation occurs during screen lock. If a predetermined operation situation does not occur, the screen lock state is maintained until the user releases it, as usual.

  First, as a preparation stage, the user manages a screen lock screen and registration information (new registration, deletion, change, etc.) (S1). This preparation step can be performed when the medical device 1 is not used, for example, when the medical device 1 is installed or maintained. Hereinafter, it is assumed that the screen storage unit 42 stores a plurality of screen lock screens including the screen lock screens 421 to 425 shown in FIG. In addition, it is assumed that the registration information storage unit 43 stores the registration information 430 illustrated in FIG.

  Use of the medical device 1 is started (S2). Based on the time information provided from the time measuring unit 45, the control unit 46 determines whether or not an operation on the medical device 1 has been performed for a certain period of time (S3). That is, the control unit 46 determines whether or not the operation signal from the operation unit 31 has not been input for a certain period of time.

  When the operation is not performed for a certain time (S3; Y), the control unit 46 selects the screen lock screen according to the presence / absence of the input of the operation status generation signal from the device monitoring unit 44, and is displayed at this time. Instead of the normal screen (examination screen, diagnostic screen, etc .; referred to as “normal screen”) displayed on the display unit 35 (S4). In the background of the screen lock screen, processing related to this normal screen is executed.

  The fact that the operation status generation signal has not been input in step S4 means that the medical device 1 is currently operating normally. In that case, the control unit 46 selects and acquires the screen lock screen 421 shown in FIG. 2A from the screen storage unit 42 and causes the display unit 35 to display it.

  On the other hand, if an operation status generation signal has already been input in step S4, it means that a predetermined operation status (operation status other than “normal” in FIG. 3) is present. In that case, the control unit 46 selectively acquires the image ID associated with the operation status identification information input together with the operation status generation signal from the registration information 430. Then, the screen lock screen specified by the image ID is acquired from the screen storage unit 42 and displayed on the display unit 35.

  Since it is rare that a predetermined operation situation occurs at this stage, it is assumed that a screen lock screen 421 indicating a normal operation situation is displayed in step S4.

  In a state where the screen lock screen 421 is displayed, when a predetermined operation situation occurs and an operation situation occurrence signal and operation situation identification information are input from the device monitoring unit 44 (S5; Y), the control unit 46 inputs The operation status corresponding to the operated status identification information is specified from the operation status included in the registration information 430 (S6).

  In addition, the control unit 46 selects and acquires the screen lock screen identified by the screen ID associated with the specified operation status from the screen storage unit 42 (S7), and the display screen of the display unit 35 is selected as the screen lock screen 421. To the selected screen lock screen (S8). At this time, the control unit 46 acquires the time from the time measuring unit 45 and displays the time on the screen lock screen (S9). This time represents the time when the screen lock screen is switched (substantially the same as the time when the predetermined operation situation occurs).

  The screen lock screen displayed in step S8 is switched to the normal screen when the user performs a predetermined screen lock release operation (password input or the like). If the operation status identified in step S6 is “error (level 3)”, the screen lock screen display processing (S7, S8) is not executed.

  The above is the basic operation mode of the medical device 1 of the present embodiment. Hereinafter, when the operation status identified in step S6 is “dialog display”, “warning”, “error (level 1)”, “error (level 2)”, “error” (Level 3) "and" Information display "will be described respectively.

[Display dialog]
FIG. 5 shows an example of the operation mode of the medical device 1 when the operation status specified in step S6 of FIG. 4 is “dialog display”.

  When the identified operation status is “dialog display” (S11), the control unit 46 confirms that “unlock” corresponding to the operation state “dialog display” of the registration information 430 is designated as off. At the same time (S12), it is confirmed that "switching" is designated to be on (S13). Receiving the confirmation results, the control unit 46 selects the screen lock screen 422 with the screen ID “lock_pic_2” from the screen storage unit 42 (S14), and displays it on the display unit 35 (S15). Further, the time is acquired from the time measuring unit 45 and displayed on the screen lock screen 422 (S16).

  Further, the control unit 46 refers to the “user notification” and confirms that it is set to off (S27). Therefore, when the operation status is “dialog display”, the notification process for the user terminal 10 is not controlled.

  The user sees the screen lock screen 422 displayed on the display unit 35 and recognizes that there is a request for dialog display (and can also recognize the time). When the user performs a predetermined screen lock release operation using the operation unit 31 (S18), the control unit 46 receives the operation signal, and displays the dialog subject to display request on the normal screen instead of the screen lock screen 422. At the same time, it is displayed on the display unit 35 (S19). This completes the screen lock operation in the case of “dialog display”.

〔warning〕
Next, an example of the operation mode of the medical device 1 when the operation status identified in step S6 of FIG. 4 is “warning” will be described with reference to FIG.

  When the identified operation status is “warning” (S21), the control unit 46 confirms that “unlock” corresponding to the operation state “warning” in the registration information 430 is designated as “OFF” ( S22), it is confirmed that "switching" is designated to be on (S23).

The user, for example, sees the above dialog displayed on the display unit 35 or the information itself, and recognizes that there is a request for information display, and recognizes the information itself (and also about the time when the information display request is made). Can be recognized.)

[Function and effect]
The operation and effect of the medical device 1 according to the present embodiment that operates as described above will be described.

  First, the medical device 1 includes a display unit 35 that displays medical information, a device monitoring unit 44 that monitors the operation status of the device, and a change in the monitored operation status (for example, from “normal” to “dialog display”). The screen lock screen displayed on the display unit 35 is switched in response to (change).

  More specifically, the medical device 1 includes a screen storage unit 42 that stores a plurality of screen lock screens 421 to 425 in advance, each of the screen lock screens 421 to 425 and the like, and a plurality of operation states (“normal” ”,“ Dialog display ”, etc.), and a registration information storage unit 43 that stores in advance registration information 430, and the control unit 46 associates with one of the plurality of operation situations. When the displayed screen lock screen (for example, the screen lock screen 421 corresponding to “normal”) is displayed on the display unit 35, the change from the one operation state to another operation state (for example, “dialog display”) Is detected by the device monitoring unit 44, the screen lock screen (“Dialog And it is adapted to display on the display unit 35 a screen lock screen 422) corresponding to the display. "

  According to such a medical device 1, the user can grasp the background processing in the screen lock state and the change in the operation status in the hardware by referring to the screen lock screen displayed by switching. (Software processing and hardware operations executed when the screen is locked are collectively referred to as “background processing”). In addition, since the screen is locked even after the operation status is changed, even if another person performs an inappropriate operation, the operation is not affected and information is not leaked.

  Therefore, according to the medical device 1, it is possible to allow the user to recognize the operation status of the device such as the processing status of the background processing when the screen is locked while preventing an operation or information leakage by others.

  Further, according to the medical device 1, when a level 2 or level 3 error or the like occurs, a message is transmitted to the user terminal 10 so that a user who is not on the device side indicates the operation status of the device when the screen is locked. (For example, a user in a remote place) can be notified. Therefore, the user can quickly grasp abnormalities in the operation status and take appropriate measures.

  The registration information 430 records information (emergency information) indicating the urgency of a plurality of operating situations. In other words, “user notification” relating to a situation in which the urgency level is equal to or higher than a predetermined level (for example, errors of level 2 and level 3) among a plurality of operation situations is set to ON, "User notification" regarding (error) is set to off. Only when an operational situation with an urgency level equal to or higher than a predetermined level occurs, a message is transmitted to the user terminal 10.

  As a result, when an operation situation with a relatively high degree of urgency occurs, the user can take quick action, while when an operation situation with a less urgency level occurs, such an action You don't bother receiving messages that tell you about the situation. In other words, the message can be notified only when the degree of urgency is high, that is, when the necessity of notifying the user is high.

  The medical device 1 is configured such that the user himself / herself can designate an operation situation with a high degree of urgency, that is, an operation situation in which it is determined that the user needs to be notified. Therefore, the presence / absence of message transmission can be set according to each user's request, and the convenience of system operation is high. Note that the presence / absence of message notification may be set as a default according to the urgency of each operation status.

  In the medical device 1, urgency information in another meaning is recorded in the registration information 430. That is, for an operation situation with a particularly high degree of urgency, such as a level 3 error, “unlock” is set to ON so that the screen lock is released as it occurs.

  For example, when there is a risk of danger to the patient, for example, when the X-ray exposure amount is too large, the time for releasing the screen lock also increases the risk. Therefore, in the present embodiment, the screen lock is automatically released when an operating situation with a particularly high degree of urgency occurs. In other words, when the patient is at risk, patient safety is given priority over information leakage.

  Whether or not the screen lock is automatically released can also be specified by the user because it is convenient for operation (of course, it may be set by default).

  In the medical device 1 according to the present embodiment, the user himself / herself specifies whether or not to switch the screen lock screen when each of the plurality of operation situations changes from another operation situation to the operation situation. The designation result is recorded in the “switch” column of the registration information 430. When a change in the operation state is detected, the control unit 46 refers to the registration information 430 to recognize whether or not to switch the screen lock screen. When the change is performed, the operation state after the change is detected. When the screen lock screen indicating is displayed and switching is not performed, the screen lock screen before switching is continuously displayed.

  Therefore, when an operation situation that is not so important that it is necessary to switch the screen lock screen occurs, an option of not switching the screen lock screen can be selected, which is convenient for operation.

  In addition, according to the medical device 1, when the operation state of the device changes, the time when the change occurs is displayed. It is possible to judge the degree of progress and to consider how to deal with it.

[Modification]
The configuration specifically described above is merely an example for suitably implementing the medical device according to the present invention. Therefore, when implementing the present invention, various modifications within the scope of the present invention can be made.

  When two or more abnormal operation situations occur during the screen lock, it is possible to display a screen lock screen associated with the most important one (such as urgency) among them. For this purpose, for example, priorities are set in advance for the operation status of the registration information 430, and each time the operation status changes, the priority of the operation status before the change and the priority of the operation status after the change. And the screen lock screen with the higher priority may be displayed.

  When the screen lock is manually released, for example, when a configuration that takes a long time to release, such as when the number of characters in the input password is large, the release operation after a predetermined operation situation occurs is another easy operation. It can be controlled to change the method. For example, when the normal input password is 15 characters, a simple password consisting of 4 characters can be set in advance when a predetermined operating condition (for example, level 2 error) occurs. it can. At this time, a message indicating that the simple password is being applied may be displayed together with the screen lock screen.

  When using a medical device configured to shift the power mode to sleep mode when it is not used for a predetermined time, the recovery time of the normal use mode or the like when a predetermined operation situation (such as a highly urgent one) occurs It is possible to control to change to the short power mode. Thereby, it is possible to shorten the time until the start of the treatment for the generated operation situation.

[Screen lock control program]
A screen lock control program according to the present invention will be described. Various operations (FIGS. 4 to 10) of the medical device 1 described above are executed according to the screen lock control program. The screen lock control program is stored in advance in a storage device such as a hard disk drive or ROM built in the medical device 1 or a storage device built in a computer or the like accessible by the medical device 1.

  The screen lock control program can be stored in any storage medium that can be read by the computer. For example, it can be stored in an optical disk, a magneto-optical disk (CD-ROM / DVD-RAM / DVD-ROM / MO, etc.), a magnetic storage medium (hard disk / floppy (registered trademark) disk / ZIP, etc.), and the like.
