Technical Field

[0001] The embodiments disclosed in this specification and the accompanying drawings relate to a medical information processing device. Background Art

[0002] There are differences in experience among surgeons who perform examinations and treatments at medical sites. In order to compensate for this difference in experience, experienced surgeons often provide advice to patients in the same place or remotely during surgery.

[0003] In addition, even when handling an inspection device, the inspection technician often sets various parameters of the inspection device based on his or her past experience. In order to provide such various medical procedures uniformly, it is desirable to provide a medical information processing device that provides support for compensating for these differences in experience. Summary of the invention

[0004] One of the problems to be solved by the embodiments disclosed in this specification and the accompanying drawings is to provide support information to make up for the difference in experience when performing medical treatment on patients. However, the problems to be solved by the embodiments disclosed in this specification and the accompanying drawings are not limited to the above-mentioned problems.

[0017] Hereinafter, the implementation of the medical information processing device and the medical information processing system having the medical information processing device will be described with reference to the accompanying drawings. In addition, in the following description, the same reference numerals are marked for components having substantially the same function and structure, and the description is repeated only when necessary.

[0018] Figure 1 This is a block diagram for explaining the overall structure of the medical information processing system 1 of this embodiment. Figure 1As shown, the medical information processing system 1 of this embodiment constitutes a so-called in-hospital system, and is equipped with a medical data generating device 2, a medical information management device 3, a medical data storage device 4, an operating device 5, and a medical information processing device 6. Moreover, these medical data generating devices 2, medical information management devices 3, medical data storage devices 4, operating devices 5, and medical information processing devices 6 are connected to each other via a network NT. In this embodiment, the network NT is composed of wired, wireless, or a combination of wired and wireless, and constitutes an in-hospital network. In addition, the network NT can also be connected to a network outside the hospital as needed.

[0019] The medical data generating device 2 is composed of, for example, a medical image diagnostic device, a bimetallic measuring device, a wearable device, etc., and generates various medical data. Here, as a medical image diagnostic device, there are, for example, an X-ray CT (Computed Tomography) device, an MRI (Magnetic Resonance Imaging) device, an X-ray diagnostic device, an ultrasonic diagnostic device, etc. The medical data generating device 2, for example, receives an operation request from the operating device 5 and performs a scan on the patient. Then, the medical data generating device 2 supplies the medical data generated by the scan to the network NT, for example, it is stored in the medical data storage device 4, or the medical information processing device 6 performs the required data processing.

[0020] The medical information management device 3 is composed of a computer device such as a server, a workstation, or a personal computer, and manages the medical data stored in the medical data storage device 4. In addition, when the user operates the operating device 5 and inputs certain medical information, the medical information management device 3 stores the input medical information in correspondence with the medical data stored in the medical data storage device 4 as needed.

[0021] The medical data storage device 4 is composed of, for example, a large-capacity hard disk drive or a data server, and stores medical data generated by the medical information processing system 1. In addition, the medical data storage device 4 allows access to the stored medical data from other devices via the network NT, and provides the requested medical data to other devices.

[0022] The operating device 5 can accept operations from the user, and operate and control various devices connected via the network NT. The operating device 5 is composed of terminal devices such as a personal computer, a tablet computer, and a smart phone. The operating device 5 can be a device carried by the user, or it can be a terminal set at a predetermined location. In addition, as the operating device 5, a trackball, a switch button, a mouse, a keyboard, a touch panel for input operation by touching the operation surface, a touch screen in which a display screen and a touch panel are integrated, a non-contact input circuit using an optical sensor, and a voice input circuit are provided as needed.

[0023] The medical information processing device 6 is composed of a computer device such as a server, a workstation, or a personal computer, and obtains and processes the medical data generated by the medical data generating device 2, or obtains and processes the medical data stored in the medical data storage device 4. The medical information processing device 6 can be composed of one computer device or a plurality of computer devices. In the case where the medical information processing device 6 is composed of a plurality of computer devices, each computer device may have a different function, or a plurality of computer devices may cooperate to perform a single process.

[0024] Figure 2 1 is a block diagram showing an example of the configuration of the medical information processing device 6 according to the present embodiment. Figure 2 The medical information processing device 6 shown is provided with a display 10 , an input interface 11 , a storage circuit 12 , a communication circuit 13 , an output interface 14 , and a processing circuit 15 .

[0025] The display 10 displays various information. For example, the display 10 displays the patient's specimen test results obtained by the medical information processing device 6, or displays the patient's medical information generated by the medical information processing device 6, or displays a GUI (Graphical User Interface) for accepting various operations from the user. In this embodiment, the display 10 is composed of a liquid crystal display, an OLED (Organic Light Emitting Diode) display, etc.

[0026] In addition, in the present embodiment, the medical information processing device 6 may also display various information on the display of the operating device 5 via the network NT. According to such a usage mode, the display 10 in the medical information processing device 6 may be omitted.

[0027] The input interface 11 receives various input operations, converts the received input operations into electrical signals, and outputs them to the processing circuit 15. The input interface 11 is implemented, for example, by a trackball, a switch button, a mouse, a keyboard, a numeric keypad, etc. In addition, when the display 10 is composed of a touch panel, the display 10 can also play the role of the input interface 11.

[0028] In addition, in the present embodiment, the medical information processing device 6 can also accept input from the operating device 5 via the network NT. That is, the user's operation input accepted by the operating device 5 is converted into an electrical signal and received as information by the communication circuit 13 of the medical information processing device 6 via the network NT. Moreover, the medical information processing device 6 can also be controlled by the input operation received as information. According to this usage method, the input interface 11 in the medical information processing device 6 can also be omitted.

[0029] The storage circuit 12 is composed of, for example, a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, and other recording media that can be read by the processor. In this embodiment, in particular, the storage circuit 12 stores programs used by the processing circuit 15, data as calculation results generated during the execution of the program, and the like.

[0030] In addition, in the present embodiment, the medical information processing device 6 can use the medical data storage device 4 as an external storage device via the network NT. That is, the medical information processing device 6 can send data as medical data to the medical data storage device 4 from the communication circuit 13 via the network NT and store it in the medical data storage device 4. Conversely, the medical information processing device 6 can receive and obtain data from the medical data storage device 4 as medical data from the communication circuit 13 via the network NT.

[0031] The communication circuit 13 provides the interface function required for the medical information processing device 6 to exchange information with the medical data generating device 2, the medical data storage device 4, and the operating device 5 via the network NT. The communication circuit 13 is installed with information communication protocols corresponding to each device in order to exchange information with other devices via the network NT. The communication circuit 13 realizes communication with other devices via the network NT according to the information communication protocol.

[0032] The output interface 14 outputs various information based on a signal supplied from the processing circuit 15 etc. In the present embodiment, the output interface 14 is realized by, for example, a speaker that outputs voice, a printer that prints data, etc.

[0033] In addition, in this embodiment, the medical information processing device 6 can also send the information to be output to the operating device 5 via the network NT. In this case, the operating device 5 outputs to the user based on the received information to be output. According to this usage, the output interface 14 in the medical information processing device 6 can also be omitted.

[0034] The processing circuit 15 is a computing circuit that performs various operations, and is composed of, for example, a processor such as a CPU or a GPU. The processing circuit 15 of this embodiment performs, for example, a process of retrieving medical data that meets a condition from medical data stored and accumulated in the medical data storage device 4, or performing various processes on the medical data obtained from the medical data storage device 4.

[0035] Therefore, if Figure 2 As shown, the processing circuit 15 of this embodiment has a scene determination function 20, an attribute information calculation function 21, a reference data acquisition function 22, a reference data display function 23, and a medical data storage function 24. The scene determination function 20 constitutes a scene determination unit in this embodiment, the attribute information calculation function 21 constitutes an attribute information calculation unit in this embodiment, the reference data acquisition function 22 constitutes a reference data acquisition unit in this embodiment, the reference data display function 23 constitutes a reference data display unit in this embodiment, and the medical data storage function 24 constitutes a medical data storage unit in this embodiment.

[0036] exist Figure 2 In the embodiment shown, each processing function performed by the scene determination function 20, the attribute information calculation function 21, the reference data acquisition function 22, the reference data display function 23, and the medical data storage function 24 is stored in the storage circuit 12 in the form of a program executable by a computer. The processing circuit 15 is a processor that realizes the function corresponding to each program by reading and executing the program from the storage circuit 12. In other words, the processing circuit 15 that has read the status of each program has Figure 2 The functions shown in the processing circuit 15 are shown in FIG. Figure 2 It is explained that a single processing circuit 15 is used to implement the scene determination function 20, the attribute information calculation function 21, the reference data acquisition function 22, the reference data display function 23, and the medical data storage function 24, but it is also possible to implement these functions by combining multiple independent processors to form a processing circuit 15 and executing programs by each processor.

[0037] Next, based on Figure 3 The data structure of the medical process record data D10 managed by the medical information processing system 1 of this embodiment will be described. Figure 31 is a diagram for explaining the relationship among the medical process record data D10, medical actions, scenes, and the medical database in this embodiment. That is, in the medical database held by the medical data storage device 4, information associated with each scene is stored as medical data.

[0038] If the Figure 3 As shown, the medical data of this embodiment is stored as medical process record data D10 for each patient. That is, one medical process record data D10 is generated and maintained for one patient. The medical process record data D10 has a data structure associated with the flow of time, i.e., a path way, and maintains past medical actions performed on the patient, current medical actions to be performed on the patient, and future medical actions scheduled to be performed on the patient.

[0039] exist Figure 3 In the example of FIG. 1 , the medical behavior for the patient F is illustrated as the medical process record data D10. Specifically, according to Figure 3 The medical process record data D10 shows that the patient F had a medical consultation D20 and a CT examination D21 in the past, a catheter treatment D22 is currently being performed, and a CT examination D23 is scheduled to be performed in the future. In this embodiment, these medical behaviors are defined as tasks. That is, one medical behavior is one task.

[0040] A medical act, i.e. a job, consists of one or more scenes. Figure 3 In the example, the medical behavior of CT examination D21 is composed of multiple scenes SC10 to SC14. Similarly, the medical behavior of catheter treatment D22 is composed of multiple scenes SC20 to SC24. The number of scenes a medical behavior has is arbitrary, but generally speaking, the more complex the medical behavior, the more scenes there are, and the more time-consuming the medical behavior, the more scenes there are.

[0041] To give a specific example, in the catheter treatment D22, scene SC20 is a scene of starting the insertion of the catheter, scene SC21 is a scene of injecting a contrast agent, scene SC22 is a scene of the front end of the catheter reaching the region of interest, and scene SC23 is a scene of placing a stent at the target site. Thus, in the catheter treatment D22, a plurality of scenes are generated according to the flow of time, that is, the channel.

[0042] In this embodiment, the image data captured in each scene is stored as medical data in the medical data storage device 4. For example, when the medical data generating device 2 such as an X-ray imaging device performs X-ray imaging of a patient having a catheter inserted, the image data of the X-ray imaging is stored as medical data in the medical data storage device 4. Figure 3 In the example, the camera image data D30 corresponding to the scene SC20, the camera image data D31 corresponding to the scene SC21, the camera image data D32 corresponding to the scene SC22, and the camera image data D33 corresponding to the scene SC23 are stored as medical data in the medical data storage device 4. Then, the camera image data D34 corresponding to the next scene, that is, the scene SC24, is finally stored in the medical data storage device 4.

[0043] Figure 4 This is a diagram showing in detail an example of the data structure of medical data D3 in the medical database constructed in the medical data storage device 4 of this embodiment. Figure 4 As shown, in this embodiment, the medical data D3 is composed of medical related information data D4 of the patient corresponding to each scene, and information corresponding to and attached to the medical related information data D4, namely, attached information data D5. Figure 3 For example, one medical data D3 is formed in correspondence with scene SC20, and another medical data D3 is formed in correspondence with scene SC21. That is, one medical data D3 is formed for each scene.

[0044] The medical-related information data D4 is information data related to medical behavior generated in each scene. Figure 3 In the example, the camera image data captured in each scene is equivalent to the medical related information data D4. For example, the camera image data D30 captured in the scene SC20 constitutes the medical related information data D4. That is, the camera image data D30 is an example of the medical related information data D4. What kind of data is equivalent to the medical related information data D4 varies according to the medical behavior and also varies according to the scene. For example, sometimes the camera image data captured by the optical camera is equivalent to the medical related information data D4, and sometimes various setting data of the medical data generating device 2 is equivalent to the medical related information data D4.

[0045] The supplementary information data D5 is data corresponding to the medical-related information data D4, and stores information that specifies the contents of the medical-related information data D4. For example, the supplementary information data D5 is stored as text information, and the supplementary information consisting of the text information is retrieved when searching for the target medical-related information data D4.

[0046] Although described in detail later, in the present embodiment, the supplementary information data D5 is automatically generated by the medical information processing device 6 during a scene during the medical procedure, and is also automatically generated by the medical information processing device 6 at the end of a scene. For example, the medical information processing device 6 performs image analysis on the camera image data obtained from the medical data generating device 2, calculates the feature quantities of the image such as the direction, thickness, and stenosis of the blood vessels, and stores and maintains them as the supplementary information data D5.

[0047] In addition, in the present embodiment, the supplementary information data D5 is automatically generated by the medical information processing device 6 as summary information of the medical behavior at the moment when a medical behavior is completed. What information is maintained as the supplementary information data D5 is arbitrary, but for example, the content of the medical behavior, the name and proficiency of the operator who performed the medical behavior, etc. are generated and maintained as the supplementary information data D5. In addition, the medical information processing device 6 can subsequently maintain information related to a good prognosis trend in the supplementary information data D5. For example, the recurrence rate of the operator who performed the medical behavior one year later, the survival rate after five years, the sequelae generation rate, etc. can be additionally stored in the supplementary information data D5. The supplementary information data D5 generated in this way does not correspond to each medical data D3, but corresponds to the medical behavior performed on the patient.

[0048] Next, based on Figure 5 The medical information generation process performed by the medical information processing device 6 of the present embodiment is described. The medical information generation process is a process implemented by the processing circuit 15 reading and executing the medical information generation processing program stored in the storage circuit 12 in the medical information processing device 6. In addition, the medical information generation process is a process started by a user such as an operator or an examination technician inputting the start of a medical procedure to the medical information processing device 6.

[0049] In addition, in the following description, reference is made to Figure 6 , taking the case of catheter treatment as a medical procedure for patient F as an example, Figure 5 That is, referring to Figure 6 The medical information generation process will be described using the medical history record data D10 of a certain patient shown in the figure. However, the medical information generation process is also performed for other medical acts.

[0050] If the Figure 5 As shown, in the medical information generation process of the present embodiment, first, the medical information processing device 6 determines the scene of the medical behavior being performed on the patient (step S10). Specifically, the scene determination function 20 of the processing circuit 15 determines the scene of the medical behavior being performed on the patient. In the present embodiment, for example, the scene determination function 20 obtains the camera image data from the medical data generation device 2 and performs image analysis of the obtained camera image data. Then, based on the analysis result of the camera image data, the scene determination function 20 determines the scene of the medical behavior being performed on the patient.

[0051] exist Figure 6 In the example of FIG. 1 , the scene determination function 20 determines the scene of catheter insertion during the medical procedure, i.e., catheter treatment, being performed on the patient through image analysis. In addition, when determining the scene, the scene determination function 20 can also refer to the cautery relationship of multiple scenes. That is, since the scene is the injection of contrast medium and the scene after the fluoroscopy scene, if the treatment is performed normally, it can be inferred that the next scene is the catheter insertion scene.

[0052] In addition, when the scene determination function 20 determines the scene, it is possible to obtain in advance information related to the medical behavior being performed on the patient. For example, the scene determination function 20 can determine in advance that the medical behavior being performed on the patient is catheterization therapy, for example, based on the user input from the operating device 5. That is, in the example described in this description, it is possible to determine in advance that the medical behavior being performed on the patient is catheterization therapy. Figure 6 In the example of FIG. 1 , it is possible to determine in advance that the medical procedure being performed on the patient is catheterization. Thus, the accuracy of scene determination by the scene determination function 20 can be improved.

[0053] Next, if Figure 5 As shown, the medical information processing device 6 calculates attribute information related to the attributes of the scene based on the scene determined in step S10 (step S12). Specifically, the attribute information calculation function 21 of the processing circuit 15 calculates attribute information related to the attributes of the scene based on the scene determined by the scene determination function 20. Figure 6 In the example of , the characteristic quantities such as the direction of the blood vessel into which the catheter is inserted, the thickness of the blood vessel, and the stenosis state of the blood vessel are calculated as the attribute information. That is, the attribute information can also be calculated by performing image analysis of the captured image data obtained from the medical data generating device 2 by the scene determination function 20. That is, the attribute information in this embodiment is that even in a certain scene of a certain medical act, there may be various conditions and scenes, so the information of the various conditions and scenes is extracted as characteristic quantities and generated as attribute information.

[0054] Next, if Figure 5 As shown, the medical information processing device 6 stores the medical data D3 in the medical data storage device 4 and stores it (step S14). Specifically, the medical data storage function 24 of the processing circuit 15 establishes a correspondence between the attribute information calculated by the attribute information calculation function 21 and the medical related information data D4 that has been established in correspondence with the patient, and stores it in the medical data storage device 4 as the medical data D3. In this embodiment, the attribute information becomes the supplementary information data D5 that is stored in association with the medical related information data D4. In addition, in this Figure 6 In the example, what is stored and stored as the medical-related information data D4 is the camera image data obtained from the medical data generating device 2.

[0055] Next, if Figure 5 As shown, the medical information processing device 6 determines whether a medical act is completed (step S16). Specifically, when the scene determination function 20 determines the scene, it is determined whether a medical act is completed after passing through the necessary scenes. If the medical act is not completed (step S16: NO), the medical information processing device 6 returns to the above-mentioned step S10 and repeats the processing after the scene determination processing.

[0056] Alternatively, the user may operate the operating device 5 to input an instruction to the medical information processing device 6 via the network NT to terminate the medical procedure. That is, the user may input the termination of the medical procedure to the medical information processing device 6 when the medical procedure for the patient is terminated.

[0057] On the other hand, when a medical act is completed (step S16: Yes), the medical information processing device 6 calculates the attribute information of the medical act (step S18). Specifically, the attribute information calculation function 21 of the processing circuit 15 calculates the attribute information of the medical act. Figure 6 In the example, for example, the proficiency score of the operator who performed the catheter treatment is calculated based on the medical process record data D10 managed by the medical information management device 3 and the medical data storage device 4, and the proficiency score is used as attribute information.

[0058] Next, if Figure 5 As shown, the medical information processing device 6 stores the attribute information calculated in step S18 as medical data D3 in the medical data storage device 4 and stores it (step S20). Specifically, the medical data storage function 24 of the processing circuit 15 stores the calculated attribute information as supplementary information data D5 associated with the entire medical behavior in the medical data storage device 4. Thus, the medical information generation process of this embodiment ends.

[0059] Figure 71 is a diagram showing an example of the structure of the medical data management table TB10 maintained by the medical information processing system 1 of the present embodiment. Figure 7 The medical data management table TB10 shown is a table for managing the medical process record data D10 and the medical data D3 stored in the medical data storage device 4. In the present embodiment, the medical data management table TB10 is stored in the medical information management device 3, for example, but its storage location is not limited to the medical information management device 3, and it can also be stored in the medical data storage device 4, or it can also be stored in the storage circuit 12 of the medical information processing device 6.

[0060] If the Figure 7 As shown, the medical data management table TB10 of the present embodiment includes the classification of medical behaviors, the proficiency score of the operator who performed the medical behaviors, and the good prognosis score of the medical behaviors. The medical behaviors and the proficiency scores can be obtained from the supplementary information data D5 maintained in the above-mentioned medical data D3. In addition, the good prognosis score is information generated by the medical information processing device 6 and the medical information management device 3 after a prescribed period of time by judging the prognosis based on the medical course record data D10 of the patient who performed the medical behavior. Therefore, after the medical behavior is performed and the prescribed period has passed, it is added to the medical data management table TB10.

[0061] Figure 8 1 is a diagram showing an example of a proficiency score calculation table TB20 used to calculate the proficiency score in the present embodiment. Figure 8 The proficiency score calculation table TB20 shown is stored in the medical information management device 3, for example, but its storage location is not limited to the medical information management device 3, and it can also be maintained in the medical data storage device 4, or it can also be maintained in the storage circuit 12 of the medical information processing device 6. In addition, the proficiency score calculation table TB20 can also be temporarily generated when the attribute information calculation function 21 of the medical information processing device 6 calculates the proficiency score.

[0062] like Figure 8 As shown, the proficiency score calculation table TB20 of the present embodiment includes the period when the medical action was performed, the operator of the medical action, and the classification of the medical action. Figure 8 In the example, since the proficiency score related to the catheter treatment of operator A is calculated, it is composed of information related to the catheter treatment of operator A. Figure 8 In the example of , it is shown that operator A has experience of 4 catheter treatments, and it can be seen that the periods are 2 times in 2022 and 2 times in 2023.

[0063] The medical information processing device 6 calculates the proficiency score based on how many times the operator has performed the medical behavior in the past and at what intervals. For example, the medical information processing device 6 can improve the proficiency score as the number of times the same classification of medical behavior is performed increases, and can reduce the proficiency score when there is a long gap in the period of the medical behavior. That is, even if it is the same operator, the proficiency score can be calculated and updated at any time according to the specified interval.

[0064] Fig. 9 1 is a diagram illustrating an example of the logic for calculating the good prognosis score by the medical information management device 3 and the medical information processing device 6 in this embodiment. Fig. 9 , medical history record data D10 of patients G, H, and I are shown. Patient G had his medical treatment performed a long time ago, and also had some medical treatment performed afterwards. Therefore, it is difficult to say that the prognosis is good, and the good prognosis score is calculated to be 0.33.

[0065] On the other hand, patient I also had his medical treatment performed long ago, and has not been given medical treatment since then. This means that patient I has a better prognosis than patient G. Therefore, the good prognosis score is calculated to be 0.80.

[0066] Moreover, not much time has passed since the medical treatment was performed on patient H. That is, the time that has passed since the medical treatment was performed on patient H is shorter than the time that has passed since the medical treatment was performed on patients G and I. Therefore, the good prognosis score is calculated as 0.50. The good prognosis score associated with the medical treatment performed on patient H will also become higher due to the longer time that has passed. Moreover, it will become lower due to the further medical treatment performed on patient H later.

[0067] Next, based on Fig.10 The medical information retrieval process performed by the medical information processing device 6 of the present embodiment is described. The medical information retrieval process is a process implemented by the processing circuit 15 reading and executing the medical information retrieval process program stored in the storage circuit 12 in the medical information processing device 6. In addition, the medical information retrieval process is a process started by a user such as an operator or an examination technician inputting the start of a medical procedure into the medical information processing device 6. That is, in the medical information processing device 6 of the present embodiment, when a medical procedure is started, the medical information retrieval process is executed in the same manner as described above. Figure 5 The medical information generation processing is performed simultaneously.

[0068] Fig.11 as well as Fig.12 This is in accordance with the above Figure 5Similarly, the medical information generation process of FIG. 1 is a diagram of the data flow of the medical information retrieval process when the catheter treatment is performed on the patient F as a medical act. Here, refer to these Fig.11 as well as Fig.12 , taking the case of catheter treatment as a medical procedure for patient F as an example, Fig.10 The medical information retrieval process is described below.

[0069] If the Fig.10 As shown, in the medical information retrieval process of this embodiment, first, the medical information processing device 6 determines the scene of the medical behavior being performed on the patient (step S30). Specifically, similar to the above-mentioned step S10, the scene determination function 20 of the processing circuit 15 determines the scene of the medical behavior being performed on the patient.

[0070] and Figure 6 The same description is given in Fig.11 as well as Fig.12 In the example of FIG. 1 , the scene determination function 20 can determine that the scene of catheter insertion is a scene of catheter treatment, which is a medical procedure being performed on a patient, by image analysis. In addition, when determining the scene, the scene determination function 20 can also refer to the cautery relationship of multiple scenes. That is, since the scene is the injection of contrast medium and the scene after the fluoroscopy scene, if the treatment is performed normally, it can be inferred that the next scene is the catheter insertion scene.

[0071] Next, if Fig.10 As shown, the medical information processing device 6 calculates attribute information related to the attributes of the scene based on the scene determined in step S30 (step S32). Specifically, similar to the above-mentioned step S12, the attribute information calculation function 21 of the processing circuit 15 calculates attribute information related to the attributes of the scene based on the scene determined by the scene determination function 20. The attribute information calculated by the attribute information calculation function 21 in this step S32 may be the same as or different from the attribute information calculated by the attribute information calculation function 21 in the above-mentioned step S12. For example, the attribute information calculated in step S32 is information calculated for retrieving reference data for the scene, and therefore can be set to a number of items less than the number of items of the attribute information calculated in step S12 in order to narrow the search range. On the contrary, a wide range of searches can also be performed by making the number of items of the attribute information calculated in step S32 greater than the number of items of the attribute information calculated in step S12.

[0072] Next, if Fig.10As shown, the medical information processing device 6 searches the medical database storing the past medical data based on the attribute information calculated in step S32, and obtains the reference data corresponding to the scene determined in step S30 (step S34). Specifically, the reference data acquisition function 22 of the processing circuit 15 searches the medical database based on the attribute information calculated by the attribute information calculation function 21, and obtains the reference data D6 corresponding to the scene determined by the scene determination function 20.

[0073] As described above, in this embodiment, the medical history record data D10 of a plurality of patients is accumulated in the medical data storage device 4 to form a medical database. Therefore, the reference data acquisition function 22 searches the medical database formed in the medical data storage device 4 to acquire reference data that matches the scenario specified in step S30.

[0074] In the present embodiment, the medical data D3 in the medical process record data D10 of the medical database is composed of the patient's medical related information data D4 and the supplementary information data D5 corresponding to the medical related information data D4. Therefore, the reference data acquisition function 22 searches the supplementary information data D5 in the medical database based on the attribute information calculated by the attribute information calculation function 21 to determine the supplementary information data D5 that matches the attribute information. Then, the medical related information data D4 corresponding to the determined supplementary information data D5 is obtained as the reference data D6. In the present embodiment, the medical related information data D4 is the camera image data of the same scene. That is, in the reference data acquisition function 22, the camera image data of other patients that are most similar to the determined scene is obtained as the reference data D6.

[0075] exist Fig.11 as well as Fig.12 In the example of FIG. 1 , a medical database accumulated in past catheter treatments for a plurality of patients is formed in the medical data storage device 4. Therefore, the reference data acquisition function 22 determines the supplementary information data D5 closest to the calculated attribute information by performing a text search on the supplementary information data D5. Then, the medical related information data D4 corresponding to the determined closest supplementary information data D5, that is, the captured image data, is acquired as the reference data D6.

[0076] As described above, the reference data acquisition function 22 may also be configured to acquire reference data corresponding to the identified scene using the proficiency information when the additional information data D5 includes the proficiency score of the operator as the proficiency information. For example, when a plurality of additional information data D5 corresponding to the attribute information is identified, the reference data acquisition function 22 may acquire the medical-related information data D4 corresponding to the additional information data D5 having the highest proficiency score as the reference data D6.

[0077] In addition, the reference data acquisition function 22 may also be configured to acquire reference data that matches the determined scenario using the good prognosis score when the supplementary information data D5 includes a good prognosis score indicating a good trend after the medical treatment. For example, when a plurality of supplementary information data D5 that match the attribute information are determined, the reference data acquisition function 22 may acquire the medical-related information data D4 corresponding to the supplementary information data D5 having the highest good prognosis score as the reference data D6.

[0078] Next, if Fig.10 As shown, the medical information processing device 6 displays the reference data D6 obtained in step S34 on the display (step S36). Specifically, the reference data display function 23 of the processing circuit 15 displays the reference data D6 obtained by the reference data acquisition function 22 on the display 10. However, the display on which the reference data display function 23 displays the reference data D6 is not limited to the display 10 of the medical information processing device 6, and the reference data D6 can be displayed on a display at any position. For example, the reference data display function 23 can display the reference data D6 on the display of the operating device 5, and can also display the reference data D6 on the display of the medical data generating device 2.

[0079] By displaying the reference data D6 on the display, the user as the operator can observe the reference data D6 of the same scene in the past in a similar situation and scenario in real time, and can perform medical treatment on the patient more accurately. That is, by observing the past reference data D6, the experience difference of the operator as the user can be compensated.

[0080] In addition, in the present embodiment, the reference data D6 may be displayed in parallel with the camera image data obtained by photographing the medical procedure currently being performed by the operator as the user. The camera image data is also the camera image data used to determine the scene in step S30. Therefore, the user as the operator can easily compare and observe the two camera image data.

[0081] In this embodiment, when the reference data D6 is displayed on the display, the supplementary information data D5 corresponding to the reference data D6, i.e., the medical-related information data D4, may also be displayed. Thus, the supplementary information data D5 as text information can also be confirmed as reference information by the operator as a user.

[0082] As described above, according to the medical information processing device 6 of this embodiment and the medical information processing system 1 having such a medical information processing device 6, it is possible to retrieve in real time the reference data D6 that matches the scene in the currently ongoing medical behavior from the medical database containing the medical process record data D10 of a large number of patients, and the operator, examination technician, etc. as a user can easily refer to the medical related information data D4 of the similar scene. In addition, even without prior preparation, the reference data D6 can be provided in real time according to the changing conditions and scenarios, so that support information that compensates for the experience differences in medical behavior can be accurately provided.

[0083] In addition, the term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or an application-specific integrated circuit (Application Specific Integrated Circuit: ASIC), a programmable logic device (such as a simple programmable logic device (Simple Programmable Logic Device: SPLD), a complex programmable logic device (Complex Programmable Logic Device: CPLD), and a field programmable gate array (Field Programmable Gate Array: FPGA)). The processor implements its functions by reading and executing programs stored in a storage circuit. In addition, it is also possible to directly program the program into the circuit of the processor instead of storing the program in the storage circuit. In this case, the processor implements its functions by reading and executing the program programmed into the circuit. In addition, the processor is not limited to a single circuit that is configured as a processor, and multiple independent circuits can be combined to form a processor to implement its functions. Moreover, multiple components can also be integrated into one processor to implement its functions.
