However, in that case, the function to be provided in the main distribution device 8b is provided in the component that is the distribution destination.

  When the wired data transmission / reception unit 36 receives a distribution request for medical data from the distribution control unit 30, the wired data transmission / reception unit 36 refers to the combined list information stored in the combined list storage unit 34 and reads the medical data read from the temporary data storage unit 33. It has a function of transmitting to a designated distribution destination via the wired network 13.

  The authentication list storage unit 32 stores in advance an authentication list for authenticating whether the medical data received by the wireless data transmitting / receiving unit 35 from the medical device 2 is medical data from the valid medical device 2.

  The distribution control unit 30 acquires authentication information included in the medical data stored in the data temporary storage unit 33 and requests authentication of the medical data by giving the acquired authentication information to the authentication unit 31.

  When the authentication unit 31 receives the authentication information of the medical data from the distribution control unit 30, the authentication unit 31 refers to the authentication list stored in the authentication list storage unit 32, thereby authenticating the medical device 2 that is the transmission source of the medical data. And a function of notifying the distribution control unit 30 of the result of whether or not the authentication is successful.

  The wired data transmission / reception unit 36 of the main distribution device 8b receives medical data transmitted from the other distribution device 8 via the wired network 13 in addition to the function of the wired data transmission / reception unit 36 of the other distribution device 8. And has a function of writing to the data temporary storage unit 33. The wired data transmitting / receiving unit 36 has a function of transmitting the medical data received from the data combining / confirming unit 37 to an arbitrary component, particularly the medical data storage server 10 via the wired network 13.

  For this reason, the medical temporary storage unit 33 of the main distribution device 8b stores each medical data received wirelessly in the main distribution device 8b and each of the other distribution devices 8.

  The data combination / confirmation unit 37 is obtained by dividing a plurality of medical data stored in the data temporary storage unit 33 from the common medical device 2 and transmitting it to one or both of the main distribution device 8b and each distribution device 8. In some cases, the combined list information stored in the combined list storage unit 34 is referred to, a function of combining a plurality of divided medical data, and the combined medical data is given to the data storage unit 38 and the wired data transmitting / receiving unit 36 With functions.

  For this reason, the medical data combined by the data combination / confirmation unit 37 is stored in the data storage unit 38.

  The data processing unit 39 of the data processing device 14 refers to the medical data stored in the data storage unit 38 of the main distribution device 8b, performs desired information processing, and then sends the processed medical data to the data storage unit 38. Has a writing function.

  The medical device position detection unit 40 refers to the medical data stored in the data storage unit 38 of the main distribution device 8b, and receives the medical data based on the authentication information of the medical device 2 included in the medical data. And the position information of the distribution device 8 or the presence position information or presence area information of the medical device 2 are detected and given to the warning unit 41, while the position of the distribution device 8 or the estimated presence position of the medical device 2 And a function of generating information for displaying an image of the existing area and giving the information to the display device 42.

  The warning unit 41 determines whether or not the medical device exists in the area where the medical device should originally exist from the position of the medical device 2 received from the medical device position detection unit 40 and the use area information of the medical device 2 set in advance. And a function of generating an alert when it is determined that the medical device 2 is outside the area where the medical device 2 should exist. For example, the alert may be a warning sound or a warning lamp, and a warning image may be displayed on the display device 42.

  The display device 42 displays the position of the distribution device 8 and the estimated position or existence area of the medical device 2 according to the image display information received from the medical device position detection unit 40, and medical information according to the alert information received from the warning unit 41. It has a function of displaying a warning image indicating that the device is outside the existing area. The display device 42 can also display medical data stored in the data storage unit 38 of the main distribution device 8b.

  Next, the operation and action of the medical system 1 will be described.

  First, when the medical device 2 is moved to a desired location and an image capturing or data measurement instruction is given from the input device 27 of the medical device 2 to the image capturing / measurement control unit 21, a control signal is output from the image capturing / measurement control unit 21. Is provided to the imaging / measurement unit 20. Then, the imaging / measurement unit 20 operates to collect medical data such as patient image data and measurement data. The imaging / measurement unit 20 provides the collected medical data to the data temporary storage unit 22 via the imaging / measurement control unit 21. Therefore, the medical data collected in the medical device 2 is temporarily stored in the data temporary storage unit 22.

  Then, for example, the trigger signal is generated manually by operating the input device 27 such as a data transmission button or automatically when the trigger generation unit 28 generates a trigger signal when a predetermined condition is satisfied. Is sent to the imaging / measurement control unit 21. Therefore, the imaging / measurement control unit 21 instructs the data transmission / reception unit 24 to transmit the medical data stored in the data temporary storage unit 22 to the distribution device 8.

  On the other hand, when the collection of medical data is completed, the medical device 2 can be moved to the next destination regardless of the transmission / reception state of the medical data. For this reason, it becomes possible to perform the next test | inspection faster, and the medical device 2 can be utilized efficiently.

  At this time, a radio wave that can be detected by the signal intensity detection unit 26 of the medical device 2 is transmitted as a signal from the signal transmission unit 29 of each distribution device 8 including the main distribution device 8b. Then, the signal intensity detection unit 26 of the medical device 2 detects the intensity of each signal by the radio wave transmitted from each distribution apparatus 8 and notifies the distribution apparatus selection unit 25 of the detected intensity of each signal. Then, the distribution device selection unit 25 compares the signal strength of the distribution device 8 received from the signal strength detection unit 26, and sets the distribution device 8 that has transmitted the signal with the highest strength as the distribution device 8 that should transmit medical data. select. Then, the distribution device selection unit 25 notifies the data transmission / reception unit 24 of the selected distribution device 8.

  The detection of the signal intensity in the medical device 2 and the selection of the distribution device 8 to be transmitted are performed at any time following the movement of the medical device 2, and the distribution device 8 to be transmitted according to the position of the medical device 2 is also dynamic. Will change.

  The data transmission / reception unit 24 of the medical device 2 divides the medical data read from the data temporary storage unit 22 into medical data in units that can be transmitted in accordance with a medical data transmission instruction from the imaging / measurement control unit 21. A transmission ID is attached to each divided medical data as identification information. And each medical data divided | segmented into the delivery apparatus 8 notified sequentially from the delivery apparatus selection part 25 is transmitted by radio. Furthermore, the transmission ID of the medical data transmitted last is written and stored in the latest transmission ID storage unit 23.

  FIG. 3 is a conceptual diagram illustrating an example of a data structure of medical data transmitted from the medical device 2 illustrated in FIG. 2 to the distribution device 8.

  The data structure of the medical data wirelessly transmitted from the medical device 2 to the distribution device 8 includes, for example, a transmission ID, data length information, CD (check digit), and data as shown in FIG. The transmission ID is a unique ID defined in the medical device 2 on the transmission side, and can be composed of an ID indicating the medical device 2 on the transmission side and a data division serial number for identifying each divided medical data. . The CD is information for verifying the integrity of medical data. Information other than the CD, for example, information such as a digest message using a hash code may be used as the integrity verification information.

  A data unit of medical data and a method of transmitting and receiving a message related to data transfer differ depending on whether the data is transmitted / received according to a communication standard or a communication layer. The medical device 2 is an image diagnostic apparatus 2b such as a portable X-ray CT apparatus, and DICOM (Digital Imaging and Communications in Medicine) data, which is a typical communication standard for medical image data, is transmitted to the medical device 2, the distribution device 8, and Prior to the collection of image data, an instruction is given from the imaging / measurement control unit 21 to the data transmission / reception unit 24, and examination reservation information (patient information or order information) by the image diagnostic apparatus 2b is obtained in advance. MWM (Modality Worklist Management Service Class) information request information is transmitted from the data transmitting / receiving unit 24 of the diagnostic imaging apparatus 2b as medical data to the information processing system 9 such as RIS, HIS, and LIS via the distribution apparatus 8 wirelessly. Is done. The MWM information transmitted wirelessly from the information processing system 9 via the distribution device 8 is received by the data transmission / reception unit 24 of the medical device 2 and is referred to when the examination is started.

  When an inspection is performed by the diagnostic imaging apparatus 2b, MPPS (Modality Performed Procedure Step) information indicating inspection execution information such as X-ray exposure information and inspection film information is created in the imaging / measurement control unit 21, and data The data is given to the transmission / reception unit 24 and transmitted to the information processing system 9 such as RIS, HIS, and LIS via the distribution device 8 by radio. For this reason, prior to wireless transmission of image data, MPPS information for notifying the start of transmission of image data is transmitted as medical data.

  When medical data such as MWM information request information, MPPS information, and image data is wirelessly transmitted from the medical device 2 as described above, the wireless data transmission / reception unit 35 of the distribution device 8 receives the data and writes it in the data temporary storage unit 33. Temporarily saved.

  However, when the medical device 2 is moving, the distribution device 8 having a large signal intensity selected as the transmission destination changes, and medical data having a relatively large data size is transferred from the medical device 2 to the distribution device 8. In this case, the medical data is divided and transmitted to a plurality of distribution devices 8. Then, each medical data received by the wireless data transmitting / receiving unit 35 of each distribution device 8 is written and temporarily stored in the data temporary storage unit 33 of each distribution device 8.

  Next, the distribution control unit 30 acquires authentication information included in the medical data stored in the temporary data storage unit 33, and requests authentication of the medical data by giving the acquired authentication information to the authentication unit 31. Then, the authentication unit 31 refers to the authentication list stored in the authentication list storage unit 32 to authenticate the medical device 2 that is the transmission source of the medical data, and distributes the result of whether or not the authentication is successful. Notify the control unit 30.

  When the distribution control unit 30 receives a notification from the authentication unit 31 that the medical device 2 is not authenticated, the distribution control unit 30 does not establish communication. Therefore, for example, if the authentication is set so that the authentication is successful only when the medical device 2 exists in the specific management area, the medical device 2 can be used only when the medical device 2 exists in the specific management area. It is possible to prevent the medical device 2 from being misused in an area incompatible with the outside inspection.

  On the other hand, if the delivery control unit 30 receives a notification from the authentication unit 31 that the medical data has been successfully authenticated, the distribution control unit 30 continues the communication and sends a message to the wireless data transmission / reception unit 35 that the medical data has been received. An instruction is sent to the device 2 and a message indicating that the medical data has been received is transmitted from the wireless data transmitter / receiver 35 to the data transmitter / receiver 24 of the medical device 2. In addition, even when the medical data transmitted from the medical device 2 by radio is interrupted and interrupted, the data transmission / reception of the medical device 2 from the wireless data transmitting / receiving unit 35 of the distribution device 8 also occurs when the medical data reception fails. A message indicating that the reception of medical data has failed is transmitted to the unit 24.

  Further, when the medical device 2 moves and the distribution device 8 that is the transmission destination of the medical data is switched during the transmission of the medical data, the message indicating that the medical data has been received is not received for a certain period of time. In some cases, so-called time-over may occur. Conversely, when the medical device 2 moves while receiving data from the distribution device 8 and the distribution device 8 is switched or wireless communication with the distribution device 8 becomes difficult, it is transmitted from the distribution device 8. Data time is over.

  For this reason, on the medical device 2 side, the data transmission / reception unit 24 receives a message indicating that the reception of the medical data has failed from the distribution device 8 or is transmitted from the message indicating that the medical data has been received or the distribution device 8. When a certain time elapses without receiving the data to be received and the time is over, it can be determined that the wireless transmission of the medical data has failed. If it is determined that the wireless transmission of the medical data has failed, the data transmission / reception unit 24 refers to the latest transmission ID storage unit 23 and retransmits the medical data with the transmission ID that failed to be transmitted to the distribution device 8. .

  In other words, the data transmission / reception unit 24 of the medical device 2 can detect switching of the distribution device 8 by monitoring a time-over or a message from the distribution device 8. For example, the data transmission / reception unit 24 can detect that the communication device has failed due to the authentication failure in the distribution device 8 by monitoring the time over. In this case, it can be determined that the delivery device 8 has been switched or the medical device 2 has moved to an area where data transmission / reception is difficult.

  When it is determined that the distribution device 8 has been switched due to movement of the medical device 2 during the transmission of medical data, the data transmission / reception unit 24 is updated when communication with the distribution device 8 becomes possible again. By referring to the transmission ID storage unit 23, a part or all of the medical data being transmitted before switching the distribution device 8 is retransmitted to the distribution device 8 after switching. Similarly, even when it is determined that transmission / reception of data has become difficult due to movement of the medical device 2, a part or all of the medical data is retransmitted to the distribution device 8 when communication with the distribution device 8 becomes possible again. To do.

  In addition, when it is determined that the distribution device 8 has been switched due to movement of the medical device 2 while data is being received from the distribution device 8, the latest transmission ID storage unit is restored when communication with the distribution device 8 becomes possible again. 23, the new distribution device 8 after switching is requested again to transmit data. Similarly, when it is determined that the transmission / reception of data has become difficult due to the movement of the medical device 2, when the communication with the distribution device 8 becomes possible again, the transmission of the data to the distribution device 8 is requested again.

  That is, since the transmission ID of the medical data (including the information transmission request) that was transmitted wirelessly from the medical device 2 side to the distribution device 8 side is stored in the latest transmission ID storage unit 23, the transmission failed. Can also be retransmitted. Thereby, the integrity of medical data can be maintained. For example, even if the patient moves to a place where radio waves do not reach while carrying the portable measuring device 2a, the data transmission / reception unit 24 refers to the transmission ID stored in the latest transmission ID storage unit 23. Since the medical data can be automatically retransmitted at the stage where the connection to the distribution device 8 is completed, there is no burden on the patient.

  Next, when each distribution device 8 successfully authenticates the medical data transmitted from the medical device 2, each distribution control unit 30 in each distribution device 8 stores the medical data stored in the data temporary storage unit 33. Is sent to the main distribution device 8b. For this reason, each wired data transmission / reception unit 36 refers to the combined list information stored in the combined list storage unit 34, and stores the temporary data storage unit in the main distribution device 8 b specified as a distribution destination in association with the medical device 2. The medical data read from 33 is transmitted via the wired network 13. Here, when each distribution device 8 fails to receive the medical data, the medical data is retransmitted from the medical device 2, so that the main distribution device 8b completes the reception from the medical device 2 and completes. Only the medical data in which is maintained will be transmitted.

  Then, the wired data transmission / reception unit 36 of the main distribution device 8 b receives the medical data transmitted from each distribution device 8 via the wired network 13 and writes it in the data temporary storage unit 33. For this reason, the data temporary storage unit 33 of the main distribution device 8b stores the medical data received wirelessly in the main distribution device 8b and each distribution device 8. Next, the data combination / confirmation unit 37 refers to the combination list information stored in the combination list storage unit 34, combines the plurality of divided medical data, and provides the combined data to the data storage unit 38 and the wired data transmission / reception unit 36. .

  For this reason, the medical data collected in the medical device 2 is stored in the data storage unit 38, while the medical data is transmitted from the wired data transmission / reception unit 36 to the medical data storage server 10 via the wired network 13. Stored. That is, the medical data collected in the medical device 2 may be divided into a plurality of distribution devices 8 and transmitted by radio as the medical device 2 moves. After being aggregated and combined in 8b, it is stored in the medical data storage server 10 as complete medical data.

  In addition, various processes such as an image reconstruction process can be performed on the medical data stored in the data storage unit 38 using the data processing device 14. The medical data is processed by the data processing unit 39, and the processed medical data is written and stored in the data storage unit 38.

  Furthermore, the approximate position of the medical device 2 can also be confirmed. In that case, the medical device position detection unit 40 of the data processing device 14 refers to the medical data stored in the data storage unit 38, and based on the authentication information of the medical device 2 included in the medical data, the medical data is stored. The received distribution device 8 is specified. Then, assuming that the delivery device 8 that has received the medical data is always the nearest delivery device 8 of the medical device, it can be estimated that the medical device 2 exists in the vicinity of the delivery device 8 that has received the last medical data. . Moreover, if the position of the delivery device 8 that has received the medical data is plotted, the approximate trajectory or movement area of the medical device 2 can be estimated.

  The medical device position detection unit 40 creates information for displaying an image of the position of the distribution device 8 or the estimated position of the medical device 2 and gives the information to the display device 42. For this reason, the display device 42 shows the estimated position and location of the medical device 2 or the distribution device 8 nearest to the medical device 2.

  4 is a diagram showing a display screen example of the position information of the medical device 2 displayed on the display device 42 of the data processing device 14 shown in FIG.

  As shown in FIG. 4, the medical facility 5 is provided with a plurality of examination rooms 6, examination rooms, accounting counters, toilets, stairs, elevators, and other facilities, and the examination car 4 can stop outside the medical facility 5. . In the medical facility 5, a plurality of distribution devices 8 are installed at predetermined intervals. For this reason, the position of each distribution device 8 is superimposed on the map of the medical facility 5.

  For example, when medical data wirelessly transmitted from a certain medical device 2 is received last by the distribution device 8 installed in the examination room C, it may be estimated that the medical device 2 exists in the examination room C. it can. Therefore, as shown in FIG. 4, an image showing the medical device 2 is displayed in the examination room C. In this way, the location and area of the medical device 2 can be grasped from the data processing device 14. For this reason, the movement instruction | indication of the medical device 2 can be performed efficiently.

  When medical data wirelessly transmitted from another medical device 2 is last received by the distribution device 8 installed in the passage, the position is displayed in the vicinity of the distribution device 8. However, from the relationship between the medical device 2 and the distribution device 8, it can be determined whether or not the medical device is outside the area where it should originally exist.

  Therefore, the warning unit 41 receives the position information of the medical device 2 or the position information of the distribution device 8 from the medical device position detection unit 40, and determines whether or not the medical device exists in a preset use area. . When it is determined that the medical device 2 is outside the area where the medical device 2 should exist, an alert such as a warning sound, a warning lamp, or a warning image is generated.

  For this reason, in particular, when the medical device 2 is a portable measuring device 2a, it is possible to confirm the movement of the patient and prepare for an accident.

  That is, the medical system 1 as described above is configured to perform data communication wirelessly between the movable medical device 2 and the distribution device 8 connected to the wired network 13. In addition, medical data can be ensured by storing the transmission ID even if wireless transmission of medical data fails so that the integrity of medical data is maintained because the target of data communication is medical data. It is made to resend to.

  For this reason, according to the medical system 1, a portable measuring device 2a carried by the patient himself / herself, an X-ray diagnostic apparatus, an ultrasonic diagnostic apparatus, which is moved by the medical facility 5 and used by an engineer or doctor, Even when the medical device 2 such as a chemical analyzer is moving, the medical data can be transferred to the distribution device 8 on the server side. As a result, the restriction of the actions of patients, technicians, and doctors, which is conventionally caused by the need to transfer medical data by connecting a medical device to a specific distribution device 8, reduces the burden on the patient's daily life. it can. In addition, since data can be transmitted and received regardless of whether the medical device 2 is moving or fixed, efficient use of the medical device 2 can be expected.

  In particular, even when the portable measuring device 2a moves, the distribution device 8 in a stronger signal state can be sequentially selected, and data can be transmitted and received while switching the distribution device 8, so that the patient can freely move around the facility. In addition to being able to move, no special time is required for sending and receiving data.

  In addition, although the medical device 2 demonstrated the example which comprises the medical system 1 so that the delivery apparatus 8 which transmits medical data according to the intensity | strength of each signal by the electromagnetic wave each transmitted from the delivery apparatus 8 may be selected, The distribution device 8 may be selected according to the method. For example, the distribution device 8 to which medical data is to be transmitted is determined in advance according to the location or area of the medical device 2, while the medical device 2 is provided with a function for detecting the location or area and the detected medical device is detected. There is a method of selecting the distribution device 8 according to the location or area where the device 2 exists.
