  Hereinafter, embodiments of the present invention will be described. However, the following description is an example of the medical image management system according to the present embodiment, and the present invention is not limited to this.

  First, a medical image management system according to an embodiment of the present invention will be described with reference to FIGS.

  The medical image management system according to the present embodiment can be applied to an operating field that is a full view of an operating room in a hospital taken by an imaging device such as a network camera (NW camera), or an operating field that is a site where surgery is performed. The present invention relates to a system that handles video data. Specifically, the first reception of receiving the first image data (moving image data), which is a video obtained by photographing with the photographing apparatus, via the first network (in-hospital video signal LAN 105). Means (NW camera video reception unit 201) and generation means (distribution still image creation / transmission unit) for generating second image data (still image data) from the first image data received by the first reception unit 201). Then, the first transmission unit (distribution still image creation / transmission unit 201) for transmitting the second image data generated by the generation unit, and the second image data transmitted by the first transmission unit are converted into the second The second receiving means (distribution still image receiving unit 206) for receiving via the second network (hospital basic information LAN 101) and the second video data received by the second receiving means through the second network And a second transmission means (distribution image distribution unit 208) for transmitting the second video data to an information terminal (medical information terminal 103) capable of browsing.

  The second image data has a smaller data size than the first image data. Typically, the first image data is moving image data, and the second image data is still image data constituting a part of the moving image data. As the still image data, for example, still image data acquired every second among moving image data, or data having a reduced data size by reducing the resolution of the moving image data can be used.

  The medical image management system according to the present embodiment may further include a first storage unit (video recording storage 205) that stores first image data. By having the first storage means, it is possible to store a video relating to the surgical field and the surgical field during the operation and to browse the video later. However, since the storage capacity of the first storage means is also limited, the process of deleting from the first storage means the first image data that has been stored for a predetermined time since being stored in the first storage means. You may have the 1st deletion means to perform. For example, the first deletion unit is configured to delete data that has been stored for 100 days or more after the first image data is stored in the first storage unit.

  The medical image management system may further include a second storage unit (in-hospital video recording storage 212) that stores the second image data. However, since the storage capacity of the second storage means is also limited, a process of deleting the second image data that has been stored for a predetermined time or longer from the second storage means from the second storage means. You may have the 2nd deletion means to perform. For example, the second deletion unit is configured to delete data that has been stored for 100 seconds or more after the second image data is stored in the second storage unit. Further, since the capacity of the second storage means is generally not larger than that of the first storage means, a capacity control means for controlling so that the capacity of the stored second image data is constant. You may have.

  The second transmission unit may transmit the second image data to the external storage device (cloud video recording storage 216) via the third network (Internet line 110). The second image data is stored in an external storage device and managed by the medical image management cloud system 109. Moreover, it is preferable that the transmission of the second image data to the external storage device by the second transmission means is performed during normal hospital business hours (for example, at night).

The first transmission unit may transmit the first image data to the external storage device via the fourth network, and store the first image data in the partial storage device.
In addition, the second video data includes information about a patient who is an imaging target of the imaging apparatus as metadata. The information related to the patient is, for example, at least one of information related to the patient ID, the name of the operating room in which imaging is performed, the name of the surgeon in charge, the elapsed time of the operation, and the operation status.

  The image output of the network camera generates a data amount of, for example, 8 MB / bps per unit even when the compressed HD video distribution is 30 fps. For example, if the image output of a large number of network cameras is directly connected to the in-hospital backbone information LAN to which a medical information terminal or the like is connected, video distribution will occupy most of the network bandwidth, and it will be serious for clinical work during hospital work hours. Due to the impact, video distribution cannot be viewed on a medical information terminal.

  Further, for example, the image output of many network cameras is directly connected to the in-hospital basic information LAN to which the medical information terminal or the like is connected, and the medical image management system connected to the in-hospital basic information LAN is connected to, for example, the operating room. The video recording of the entire view of the operating room (surgical site) and the video of the surgical site (surgical field) in the form of adding the time information of the start of preparation, the start of surgery, the end of surgery, and the end of operation room cleanup is described above. Because of network load problems.

  Therefore, as described above, the video information can be distributed on the medical information terminal by reducing the large-sized moving image data communicated by the in-hospital video signal LAN and communicating on the in-hospital basic information LAN. It becomes possible to watch.

  The NW camera video can be viewed on a medical information terminal connected to the in-hospital basic information LAN, and the medical image management system connected to the in-hospital basic information LAN can be prepared, for example, in an operating room. In addition, it is possible to record video in a format with information on the start of the operation, the end of the operation, and the end of the operation room, and the operating room staff can easily estimate the expected time until the operation is completed. It is easy to provide notification accurately and accurately.

  Next, the medical image management system according to the present invention will be described in detail with specific examples.

  In this embodiment, an NW camera is used that is installed in an operating room and images a surgical field and visualizes it. A patient information system is used to obtain patient information of a patient undergoing surgery. A medical information terminal is used to view video distribution etc. in the operating room. This embodiment can also be applied when using an NW camera that visualizes the surgical field.

(Surgery status display system)
Conventionally, medical personnel in hospitals have confirmed the progress of surgery by viewing the scheduled delivery time, viewing the video distribution of the entire operating room, or referring to the surgery schedule entered in advance in the surgery schedule display system. (Japanese Patent Laid-Open No. 2007-122174). However, in the conventional system, it is difficult for staff in the operating room to easily and accurately notify the medical staff in the hospital of the expected time until the end of the operation. Therefore, by using the following operation status display system, video recording can be performed in a format with information on start of operation room preparation, start of operation, end of operation, and end of operation room clean-up, expected until the end of the operation. It becomes easy for the operating room staff to easily and accurately notify the medical personnel in the hospital of the time. Therefore, acquisition means for acquiring information on the operating room status (operating room name, operating doctor, operating department, operating patient name, elapsed time of operation, and operating status), Providing a display device capable of displaying information related to the operating room status, comprising display control means for controlling display of the information on the display device, is suitable for grasping the surgical status of medical personnel. It was found. In addition, the information regarding the status of the operation may be any of during the operation, the remaining time until the end of the operation, during the preparation for the operation, and during the tidying up, but is not limited thereto.
Details will be described below.

  FIG. 14 shows a configuration example of metadata 1201 of NW camera data among the patient information data stored in the patient information storage 211 shown in FIG. An operating room name 1401 is stored. 1402 stores operation field recording or operation field recording as the type of camera. 1402 stores the operation preparation start time. 1403 is the completion of the operation preparation and the operation start time is stored. 1404 is the end of the operation and the cleaning start time is stored. In 1405, a cleanup end time is started.

  The video recordings 1403 to 1404 correspond to the video recording 1006 of the surgical preparation record of FIG. When the video record 1006 of the surgical preparation record is stored only in the video recording storage 205 of the NW camera management system, the item 1407 of the surgical preparation record data is “unsaved”, and the in-hospital video of the medical image management in-hospital system When stored in the recording storage 212, “saved state” is stored, and when stored only in the video recording storage 214 of the medical image management cloud system, “cloud” is stored. Surgery preparation records are important for video recordings in the operating field. When a medical accident occurs, for example, whether the pre-operational confirmation of the operation equipment has been sufficiently performed or the equipment has been correctly prepared is not recorded unless there is a preoperative record. When the type of the NW camera is the surgical field, the operation preparation state has no meaning of recording, and the operation preparation record data item 1407 is recorded as “none”.

    The video records 1404 to 1405 correspond to the video record 1007 of the surgical record in FIG. Corresponding to the storage status of the video record 1007 of the surgical record, the item 1408 of the surgical record data is recorded as “unsaved”, “saved state”, “cloud”, or “none”.

  The video recordings 1405 to 1406 correspond to the surgical cleanup record 1008 in FIG. Corresponding to the storage status of the video record 1008 of the surgical cleanup record, the surgical cleanup record data item 1409 is recorded as either “not saved”, “saved state”, “cloud”, or “none”. For example, if there is no post-operative record, it will not be recorded as to whether or not you have noticed a malfunction of the equipment after the operation of the surgical equipment and whether or not the post-operative equipment is available. In this case, since the surgical cleanup state has no meaning of recording, the surgical cleanup record data item 1409 is recorded as “none”.

  Next, the processing procedure of the medical image management system in the present embodiment will be described using the flowchart of FIG.

  In step S <b> 801, the operating room staff accesses the operation status display unit 208 of the medical image management in-hospital system 108 from the medical information terminal 103 and displays the operation status display screen 301 on the medical information terminal 103. The information on the operation status display screen 301 is generated and redisplayed every second from the status data of the operation status information 1101 stored in the operation status information storage 218.

In step S <b> 802, the operating room 3 that is “finished” is selected from the operating room status 502 on the operating status display screen 301. As shown in FIG. 15, the operation room monitor display screen 303 is transitioned to. In the background portion of the display such as 1501 and 1502 in FIG. 15, an image of the current operating room is displayed. 17 to 19, 23, and 24, the current operating room status is displayed as in FIG. 7.
This corresponds to the state 1001 in FIGS. Since the “cleaning up” operating room is in the “waiting for operation preparation start” state and the patient to receive the operation is not assigned, the patient ID input for displaying the patient information input screen 1501 for designating the patient is prompted.

  In step S803, when the patient ID is input, the operation status display unit 208 makes an inquiry to the patient information system 104 connected on the hospital basic information LAN based on the patient ID, and the patient's name, sex, date of birth, etc. The basic patient information, the department, the surgeon, etc. are acquired and displayed on the patient information input screen 1501 (FIG. 16). When there is no patient information system 104 or when connection is not possible, necessary patient information may be manually input on the patient information input screen 1501. On the patient information input screen 1501, the preparation monitoring button 502 is clickable (step S804). A button 1502 is pressed at the timing of starting preparation for surgery. Based on the patient information, the operation status display unit 208 newly adds NW camera data metadata to the patient information data stored in the patient information storage 211. The time when the button 1502 is pressed is recorded as the operation preparation start time 1403 in FIG. The operation preparation record 1407 is initially set to “none”, the operation record 1408 is initially set to “none”, and the operation cleanup record 1409 is initially set to “none”. Transition is made to the state 1002 in FIGS. 4 and 10, the operation room monitor display screen 303 shows that the operation status 703 is “Preparing” and the button 704 is “Start surgery” as shown in FIG. 7. It becomes a state that prompts the state transition. In all the medical information terminals 103 connected to the in-hospital basic information LAN, the operation status display sections 301, 302, and 303 indicating the operation status are all displayed by the operation status display unit, and the operation status in the third operating room is “in preparation”. Is displayed, and the operating room staff can easily notify the medical staff in the hospital of the operating status of the third operating room.

  The operating room staff enters the room of the patient and the surgeon, can start the operation, and presses the “start operation” button 704 at the timing of starting the operation (step S806). The time when the “start operation” button 704 is pressed is recorded as the operation start time 1404 in FIG. When the NW camera is an NW surgical field camera, the operation preparation record 1407 is recorded as “not acquired”. Transition is made to the state of 1003 in FIGS.

  In the subsequent step S807, the state is the state of 1003 in FIGS. 4 and 10, and the operating room monitor display screen 303 displays “in operation” as the operation status 703 as shown in FIG. A “remaining 30 minutes” button 1705, a “remaining 10 minutes” button 1706, and a “completion of operation” button to be pressed when the operation is completed are displayed when the operation time is 30 minutes. In all the medical information terminals 103, the operation status displays 301, 302, and 303 showing the operation status by the operation status display unit are all displayed, and the operation status of the third operating room is displayed as “in operation”. It is possible to easily notify the medical personnel in the hospital of the operation status in the third operating room.

  In the subsequent step S808, the operation room staff presses the “remaining 30 minutes” button 1705 at the timing when the operation progresses and the remaining time for the operation is about 30 minutes. Transition is made to the state 1004 in FIGS.

  In the subsequent step S809, the state is the state 1004 in FIGS. 4 and 10, and the operating room monitor display screen 303 displays “30 minutes remaining” in the operating status 703 as shown in FIG. In the display of “remaining 30 minutes”, the remaining time decreases by 1 minute each time 1 minute elapses.
