When the user wearing the wireless tag unit 31 approaches a predetermined distance, the reading device 30 is wireless. Information of the tag unit 31 can be read.

  Next, detailed functions of the medical information management apparatus of the present invention will be described.

  The medical image display device (information terminal 20) of the present invention controls the display state using the reading device 30 and the wireless tag unit 31, and is known to a third party such as patient personal information included in the medical image information. Confidential information that is not desired to be disclosed is disclosed only to authorized users in advance, and the confidential information is not disclosed to other users or third parties. In addition, the criteria for confidential information that is not disclosed will be clarified, and all personal information that violates the Personal Information Protection Law will be undisclosed. Then, the information terminal 20 reads the information of the wireless tag unit 31 so that the confidential information can be displayed only to a user who is permitted in advance.

  Therefore, the information terminal 20 itself is provided with a function for disclosing confidential information. The information terminal 20 reads the information of the wireless tag unit 31 with the reading device 30, and a hospital user wears the wireless tag unit 31. The user information is read to recognize the presence of the user, and the secret information is displayed only to the authorized user.

  Next, the operation of the medical image display apparatus of the present invention will be described with reference to the flowchart of FIG. The flowchart in FIG. 2 shows a display operation performed under the control of the CPU 23 and the display control unit 26.

 First, step S1 is a display start step, and it is assumed that the information terminal device 20 capable of reading the information of the identification device (wireless tag unit 31) is prepared. In the next step S2, medical image information (such as a captured image) of the patient is displayed on the display unit 22 under the control of the display control unit 26, but the secret information set in advance is an undisclosed item. Therefore, confidential information such as personal information is not displayed on the information terminal 20 at this stage.

  When the user wearing the wireless tag unit 31 approaches in step S3, the reading device 30 of the information terminal 20 reads the information of the wireless tag unit 31, and determines whether the user is an authorized user based on the read identification information. To do. It should be noted that a usable user is registered in the information terminal 20 in advance, the registered information is compared with the read user information, and it is determined that the user is permitted only when they match. Of course, a user who is not wearing the wireless tag unit 31 or a user who is not registered is determined as an unauthorized user. Alternatively, in step S3, the user may be prompted to input a user ID and a user name to improve security.

  As a result of the determination, if it is recognized that the user is an authorized user, in the next step S4, the confidential information that was the non-disclosure item is automatically disclosed and displayed. Thereby, the user can view medical image information including personal information.

  FIG. 3 exemplifies the items of the confidential information to be undisclosed as described above, and may include items related to the patient himself such as a patient name and items such as a doctor in charge who diagnosed the patient. FIG. 3 shows only an example, and the addition and deletion of secret items can be arbitrarily set.

  FIG. 4 shows the display screen at step S2, and FIG. 5 shows an example of the display screen at step S4.

  In FIG. 4, the patient's personal information portion is left blank and is not displayed, and it is impossible to know which patient information is at this stage. Further, in FIG. 5, the patient's personal information (information in the circled part in the figure) is displayed, and the user can know which patient information is at this stage.

  Thus, confidential information including personal information can be viewed only by authorized users. In step S4, when the user leaves the information terminal 20, the information of the RFID tag unit 31 cannot be read. Therefore, the CPU 23 determines that the user is absent, the display screen automatically returns to the state shown in FIG. It becomes non-disclosure and can be prevented from leaking to a third party.

  Next, another embodiment of the medical image display apparatus of the present invention will be described using the flowchart of FIG. In this embodiment, a mode for disclosing / not disclosing confidential information can be selected.

 In the flowchart of FIG. 6, first, step S11 is a display start step, and it is assumed that an information terminal device 20 capable of reading the information of the identification device (wireless tag unit 31) is prepared.

  In the next step S12, medical image information is displayed on the display unit 22 under the control of the display control unit 26, but items of confidential information such as preset personal information are not disclosed. Therefore, no secret information is displayed on the information terminal 20 at this stage.

  When the user wearing the wireless tag unit 31 approaches in step S13, the reading device 30 of the information terminal 20 reads the information of the wireless tag unit 31, and determines whether or not the user is an authorized user based on the read user information. To do. Alternatively, the user is prompted to input a user ID and a user name, and it is determined whether or not the user is truly authorized. Note that the user ID and the user name are input in order to further improve the security, and in some cases, only the information reading of the wireless tag unit 31 can be performed.

  If it is determined that the user is an authorized user as a result of the determination, in the next step S14, the user performs a special operation and maintains the display of confidential information even when the user leaves as a measure when the user leaves the seat. The first mode or the second mode in which the confidential information is automatically hidden when it is away can be selected.

  After the user selects the mode, in the next step S15, the non-disclosure item of confidential information is automatically displayed. Thereby, the user can see medical image information including confidential information such as personal information.

  Next, a case where the user leaves the information terminal 20 and is absent will be described. If the user has set the first mode, the process proceeds to step S16, and the confidential information is displayed as it is. This is to prevent the display / non-display of confidential information from frequently switching when the user leaves the seat for a short time.

  On the other hand, if the second mode is set, the process proceeds to step S17, and the confidential information is not displayed even if the user is away for a short time. In this case, the concealment effect is further increased. When the user who has left the seat returns again, the reading device 30 of the information terminal 20 returns to the state of step S15 to read the information of the wireless tag unit 31, and the image data including the confidential information is displayed.

  Further, in the first mode, when the user leaves the seat and does not return within a predetermined time, it is possible to set the mode (third mode) in which the display of the confidential information is stopped and is not displayed. The special operation may be performed after step S15.

  As described above, according to the medical image display apparatus of the present invention, only the user who has registered in advance can view the confidential information, so that leakage of the confidential information can be prevented accurately. Further, the use of the RFID tag unit 31 eliminates the risk that confidential information will be viewed by a third party even if the user hides the confidential information or makes an operation mistake. it can. In addition, it is possible to clarify the criteria for non-disclosure personal information. Furthermore, since the display / non-display mode of the secret information can be switched, the leakage of personal information can be further prevented.

  The present invention is not limited to the above description, and various modifications can be made without departing from the scope of the claims.
