[0001] The present invention relates to a vascular access mapping system. [Background technology]

[0002] In hemodialysis, a vascular access such as a shunt is placed in a part of the subject's arm or other area to enable blood circulation between the subject (e.g., a patient) and the dialysis machine. Vascular access management is sometimes performed using a document called a vascular access map, which compiles information about the vascular access, such as ultrasound images of the area where the vascular access is placed and the shape of the blood vessels in that area. Currently, vascular access maps are created in any format by medical professionals, such as physicians, and there is no prescribed format. For this reason, it is difficult to say that information about vascular access maps is being shared efficiently.

DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the present invention will be described with reference to the drawings.

[0018] The vascular access mapping system 1 shown in Fig. 1 is installed in a medical institution 2 such as a hospital or clinic, and enables efficient information sharing of a subject's vascular access map. In this embodiment, the subject is a patient. Hereinafter, vascular access will also be abbreviated as "VA."

[0019] The VA mapping system 1 includes an ultrasound inspection device 3, an image server 4, a medical terminal 5, a report server 6, a printer 7, a subject terminal 8, and an information providing server 9.

[0020] The ultrasound examination device 3, image server 4, medical terminal 5, report server 6, and printer 7 can communicate with each other via a dedicated network N1, which is a local network dedicated to the medical institution 2. Each of these components is equipped with a communication module that can be connected to the dedicated network N1. The dedicated network N1 is, for example, an HIS (Hospital Information System) network. In FIG. 1, the components enclosed by a frame representing the dedicated network N1 indicate that they can be connected to that network.

[0021] The subject terminal 8 and the information providing server 9 can communicate with each other via a public network N2 provided within the medical institution 2 (hereinafter also referred to as "hospital"). The subject terminal 8 and the information providing server 9 are equipped with communication modules that can be connected to the public network N2. The public network N2 is, for example, a public wireless LAN (Local Area Network) equipped with a wireless access point (not shown), and is open to patients. In FIG. 1, the configuration enclosed by a frame representing the public network N2 indicates that it can be connected to the network.

[0022] (Ultrasound inspection device 3) The ultrasound examination device 3 includes a probe 30 and a main body 31. The probe 30 has multiple probes that transmit ultrasound waves to a part of the patient's body, such as the arm, where the VA is located, and receive the waves reflected at that part. A medical professional, such as a clinical engineer, operates the probe 30 to perform an ultrasound examination on that part.

[0023] The main body 31 of the ultrasound examination device 3 has a control device composed of a computer, a display device, and an input device. The control device generates ultrasound image information Gu showing an ultrasound image U (see FIG. 4(b)) of the area where the ultrasound examination was performed based on the reflected waves received by the probe 30. The control device also generates functional test image information Gf showing a functional test image F (see FIG. 4(c)) of the blood vessels in that area. The display device displays the ultrasound image U and the functional test image F. The input device consists of a keyboard, mouse, touchpad, etc., and accepts input operations by medical professionals.

[0024] The functional test images F include (i) pulse mode images for evaluating vascular function such as shunt blood flow (FV: Flow Volume) and vascular resistance index (RI: Resistance Index), and (ii) color Doppler mode images for evaluating vascular morphology such as vascular diameter and depth from the skin surface.

[0025] A medical professional operating the ultrasound examination device 3 can use an input device to input identification information Di, which is the ID of the subject (patient), and vascular evaluation information B1, which will be described later, into the control device. Note that the vascular evaluation information B1 may be generated by the control device based on an ultrasound examination. The control device of the ultrasound examination device 3 links the generated ultrasound image information Gu and functional test image information Gf to the identification information Di, and transmits them to the image server 4 with a timestamp indicating the date and time the ultrasound examination was performed.

[0026] (Image Server 4) The image server 4 is a file server (storage server) configured, for example, by a DICOM server, etc. The image server 4 stores the ultrasound image information Gu and functional test image information Gf received from the ultrasound inspection device 3, linked to the identification information Di and given a timestamp.

[0027] (Medical terminal 5) The medical terminal 5 is an information terminal used by medical personnel such as doctors at the medical institution 2, and in this embodiment is configured as a tablet terminal. As shown in FIG. 2 , the medical terminal 5 includes a control unit 50, a storage unit 51, an imaging unit 52, an input unit 53, and a display unit 54.

[0028] The control unit 50 is a microcontroller including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). In the control unit 50, the CPU reads out a control program stored in the ROM and controls the overall operation of the medical terminal 5 while using the RAM as a work memory.

[0029] The storage unit 51 is a non-volatile memory such as a flash memory or an EEPROM (Electrically Erasable Programmable Read-Only Memory). The storage unit 51 stores programs and data, including application programs, used by the control unit 50 to perform various processes as needed. The storage unit 51 also stores data generated or acquired by the control unit 50 performing various processes. The various types of information stored in the storage unit 51 in this embodiment will be described later.

[0030] The photographing unit 52 is a digital camera built into the medical terminal 5. In this embodiment, the photographing unit 52 photographs a part of the patient (for example, an arm) where a VA is provided, and generates photographed image information Gp indicating a photographed image P (see FIG. 3) showing the part.

[0031] The input unit 53 is configured, for example, by a capacitive touchpad, and accepts input operations by a medical professional. The touchpad is translucent and is placed in front of the display unit 54. The medical professional performs input operations on the control unit 50 by touching the input unit 53. The touch operation is performed by the medical professional's finger, a stylus pen, or the like.

[0032] The display unit 54 is composed of a liquid crystal display, an organic EL (Electro-Luminescence) display, or the like, and displays images under the control of the control unit 50. The display unit 54 and the input unit 53 of this embodiment form a touch panel 5T of the tablet terminal.

[0033] The control unit 50 includes, as main functional units, an information acquisition unit 50a, a VA information generation unit 50b, and a display control unit 50c.

[0034] The information acquiring unit 50a acquires the photographed image information Gp from the photographing unit 52. The information acquiring unit 50a also queries the image server 4 and acquires the ultrasound image information Gu and the functional test image information Gf using at least one of the timestamp and the identification information Di as a key. The key may be input from the input unit 53. Note that the information acquiring unit 50a may acquire the ultrasound image information Gu and the functional test image information Gf directly from the ultrasound examination device 3 by connecting the medical terminal 5 directly to the ultrasound examination device 3 via wired or wireless communication. The identification information Di may be transmitted from the ultrasound examination device 3 and acquired by the information acquiring unit 50a, or may be input from the input unit 53 of the medical terminal 5.

[0035] The information acquiring unit 50a can also acquire at least one of vascular evaluation information B1, progress information B2, and detailed VA information B3, which will be described later. The vascular evaluation information B1, progress information B2, and detailed VA information B3 may be input by a medical professional using the input unit 53 and then acquired by the information acquiring unit 50a. The vascular evaluation information B1, progress information B2, and detailed VA information B3 may also be transmitted from a terminal (a terminal other than the illustrated medical terminal 5) used in the medical institution 2 that is permitted to connect to the dedicated network N1, and then acquired by the information acquiring unit 50a. The vascular evaluation information B1 may be transmitted from the ultrasound inspection device 3 to the medical terminal 5 via the image server 4 together with ultrasound image information Gu, etc., and then acquired by the information acquiring unit 50a. The information acquiring unit 50a stores the above-mentioned various acquired information in the storage unit 51.

[0036] Here, the information stored in the storage unit 51 in this embodiment will be described. The storage unit 51 stores VA information Dv, which is a data set related to the VA of a subject (patient), report information Dr indicating a VA map R (see FIG. 3), and identification information Di for identifying the subject associated with the VA information Dv and the report information Dr. The VA information Dv and the report information Dr are generated by a VA information generation unit 50b.

[0037] The VA information Dv includes photographed image information Gp, ultrasound image information Gu, functional test image information Gf, vascular map information A1, position information A2, vascular evaluation information B1, progress information B2, and detailed VA information B3. Of these pieces of information, at least the vascular map information A1 and position information A2 are input by a medical professional using the input unit 53 and stored in the memory unit 51.

[0038] 3, the vascular map information A1 indicates the shape of blood vessels superimposed on the photographed image P. For example, the vascular map information A1 may be information that schematically indicates the shape, width, position, etc. of arteries and veins in the patient's arm or the like shown in the photographed image P. The vascular map information A1 is input by a medical professional such as a doctor drawing with a stylus pen or finger on the input unit 53 of the touch panel 5T on which the photographed image P is displayed.

[0039] The position information A2 is a position in the photographed image P corresponding to a part of a patient's body, such as an arm, where an ultrasound examination was performed by the ultrasound examination device 3. In FIG. 3, a star-shaped icon corresponds to the position information A2.

[0040] The blood vessel evaluation information B1 indicates at least one of functional evaluation and morphological evaluation of the blood vessels at the site where the ultrasound examination was performed. The functional evaluation includes shunt blood flow volume (FV), vascular resistance index (RI), etc. The morphological evaluation includes (i) blood vessel diameter, (ii) blood vessel depth from the skin surface, and (iii) blood vessel properties such as blood vessel hardness and blockage.

[0041] Progress information B2 is information indicating the progress of the site where the VA is installed, and includes the examination date and time when the ultrasound examination was performed, the treatment details, the treatment date, and the occlusion date. In other words, progress information B2 can be said to be the treatment history of the patient in whom the VA is installed. The examination date and time may be acquired from the ultrasound examination device 3 via the image server 4, etc. The treatment details are treatment details related to the VA, such as VAIVT (Vascular Access Intervention Therapy), represented by PTA (Percutaneous Transluminal Angioplasty), which is a treatment for VA stenosis. The treatment date is the date on which treatment related to the VA was performed. The occlusion date is the date on which stenosis or occlusion of the VA (e.g., shunt) was confirmed.

[0042] The VA detailed information B3 is information indicating the VA type, VA position, etc. The VA type is an autologous intravenous shunt, an artificial intravascular shunt, an arterial superficialization, a dialysis catheter, etc. The VA position is the position where the VA is installed on the patient's body, such as the right forearm, right upper arm, left forearm, left upper arm, right lower leg, left lower leg, etc.

[0043] In this embodiment, among the information included in the VA information Dv, the blood vessel evaluation information B1, the progress information B2, and the detailed VA information B3 constitute the auxiliary information B that can be provided to the subject terminal 8.

[0044] Returning to the explanation of the control unit 50, the VA information generation unit 50b generates VA information Dv from various pieces of information acquired via at least one of the input unit 53 and the information acquisition unit 50a. Specifically, the VA information generation unit 50b associates the position information A2 with the ultrasound image information Gu, and also associates the blood vessel evaluation information B1 with the functional test image information Gf, to generate the VA information Dv. It goes without saying that there may be multiple sets of associated position information A2 and ultrasound image information Gu. Similarly, there may also be multiple sets of associated blood vessel evaluation information B1 and functional test image information Gf.

[0045] In addition, based on the VA information Dv, the VA information generation unit 50b generates report information Dr that indicates a VA map R, which is an image in which vascular map information A1 and position information A2, and vascular evaluation information B1 are displayed superimposed on the captured image P.

[0046] An example of a VA map R is shown in Figure 3. In this VA map R, vascular evaluation information B1 indicating the functional evaluation of blood vessels is written (displayed as text) in a position that does not overlap with the patient's arm (the subject's body part) shown in the captured image P. In the VA map R, the examination date and time are written above the display position of the vascular evaluation information B1.

[0047] The storage unit 51 stores the VA information Dv, identification information Di, and report information Dr for each patient at the medical institution 2. If there are multiple pieces of VA information Dv and report information Dr for one patient, these pieces of information are accumulated as historical data of the patient.

[0048] The display control unit 50c controls the display operation of the display unit 54 based on the VA information Dv and the report information Dr, and causes the display unit 54 to display an image of information related to the VA. Under the control of the display control unit 50c, the display unit 54 operates as follows.

[0049] The display unit 54 is capable of displaying a VA map R as shown in FIG. 4(a). When a designation input is made using the input unit 53 for a display position of position information A2 in the VA map R, the display unit 54 displays an ultrasound image U indicated by ultrasound image information Gu corresponding to the position information A2 in a pop-up format as shown in FIG. 4(b). When a designation input is made using the input unit 53 for a display position of vascular evaluation information B1 in the VA map R, the display unit 54 displays a functional test image F indicated by functional test image information Gf corresponding to the vascular evaluation information B1 in a pop-up format as shown in FIG. 4(c). The designation input is made by a touch operation (e.g., tap) on the input unit 53. The ultrasound image U or the functional test image F may be displayed in a pop-up format in any area of ​​the image displayable area of ​​the display unit 54.

[0050] In addition to the above functions, the control unit 50 can generate a two-dimensional code to allow the subject terminal 8 to access the information providing server 9 in response to an instruction input using the input unit 53, and display the code on the display unit 54 as shown in Figure 5.

[0051] Furthermore, the control unit 50 associates the VA information Dv and report information Dr generated in the VA information generating unit 50b with the identification information Di, and transmits them to the report server 6 via the dedicated network N1.

[0052] (Report Server 6) The report server 6 is a file server (storage server) that stores the VA information Dv and report information Dr linked to the identification information Di received from the medical terminal 5. The report server 6 can also be accessed from other terminals (terminals other than the medical terminal 5 shown) used by medical professionals within the medical institution 2 via the dedicated network N1. Therefore, the VA information Dv and report information Dr are shared within the medical institution 2. The report server 6 may be an electronic medical record server, an examination system server, or the like already installed in the medical institution 2. The report server 6 may also receive the VA information Dv and report information Dr from the medical terminal 5 via another server.

[0053] (Printer 7) The printer 7 receives the report information Dr from the medical terminal 5 via the dedicated network N1 and outputs (prints on paper) a report image R as shown in FIG. 3. The printer 7 outputs the report image R in response to an instruction input using the input unit 53 of the medical terminal 5. The printer 7 may also receive the report information Dr from the report server 6 and output the report image R.

[0054] (Subject terminal 8) The subject terminal 8 is an information terminal carried by a patient who is a subject, and is configured, for example, as a smartphone. Note that the subject terminal 8 may also be carried by a person related to the subject, such as the patient's family, guardian, or guardian.

[0055] 6, the subject terminal 8 includes a control unit 80, a storage unit 81, an imaging unit 82, an input unit 83, and a display unit 84. These components are the same as those of the medical terminal 5, so the following mainly describes functions that differ from those of the medical terminal 5.

[0056] The control unit 80 of the subject terminal 8 reads the two-dimensional code to access the information providing server 9 and executes the auxiliary report information generation process described below in accordance with an application program (hereinafter referred to as a dedicated application) stored in the storage unit 81. The dedicated application may be downloadable, for example, from a uniform resource locator (URL) indicated by the medical institution 2. The control unit 80 that executes the dedicated application includes, as main functional units, a reference value calculation unit 80a, a state evaluation unit 80b, and an auxiliary report generation unit 80c. These functional units will be described together with the auxiliary report information generation process described below.

[0057] The storage unit 81 stores identification information Ti, which is the ID of the subject (patient) at the medical institution 2. For example, the identification information Ti is input by an operation using the input unit 83 of the subject terminal 8 when downloading a dedicated app, and is stored in the storage unit 81. Furthermore, when the subject terminal 8 acquires auxiliary information B in response to execution of an auxiliary information provision process described below, the storage unit 81 stores the acquired auxiliary information B. Furthermore, the storage unit 81 stores auxiliary report information Ts generated by execution of an auxiliary report information generation process described below.

[0058] The photographing unit 82 is a digital camera built into the smartphone, and is used to read a two-dimensional code displayed on the medical terminal 5, as shown in Fig. 5. The input unit 83 and the display unit 84 form a touch panel 8T of the smartphone.

[0059] (Information Server 9) The information providing server 9 receives and stores the auxiliary information B and the identification information Di from the report server 6 via one-way communication. Specifically, the information providing server 9 is connected to the report server 6 via a one-way communication cable 9a. One-way communication is also called simplex communication. The one-way communication cable 9a transmits data only in one direction from the report server 6 to the information providing server 9. The one-way communication cable 9a may be, for example, an RS-232C cable or a cable incorporating a USB (Universal Serial Bus)-serial conversion module that supports high-speed communication using FT232H.

[0060] The information providing server 9 includes a control unit including a CPU, a ROM, a RAM, etc., and a storage device such as an SSD (Solid State Drive) and an HDD (Hard Disk Drive). In the control unit of the information providing server 9, the CPU reads out a control program stored in the ROM and can execute the auxiliary information providing process shown in Fig. 7 using the RAM as a work memory. The information providing server 9 can provide auxiliary information B to the subject terminal 8 by executing the auxiliary information providing process. Before executing the auxiliary information providing process, the information providing server 9 receives auxiliary information B from the report server 6, and the auxiliary information B is stored in the storage device of the information providing server 9.

[0061] (Auxiliary information provision processing) First, the information providing server 9 (CPU) determines whether or not a request for providing auxiliary information B has been made from the subject terminal 8 (step S901). The request for providing information from the subject terminal 8 is made as follows.

[0062] In response to an instruction input by a medical professional using the input unit 53, the medical terminal 5 displays a two-dimensional code on the touch panel 5T (display unit 54), as shown in Fig. 5. The two-dimensional code generated by the control unit 50 of the medical terminal 5 indicates encrypted data including, for example, a one-time password, a data-specific ID of the auxiliary information B that is permitted to be provided to the subject terminal 8, identification information Di of the subject (patient), and a timestamp indicating the time the two-dimensional code was generated. The subject terminal 8 reads the two-dimensional code displayed on the medical terminal 5 with the imaging unit 82 in accordance with the dedicated app described above, and then requests the information providing server 9 to provide the auxiliary information B.

[0063] 7, when a provision request is received from the subject terminal (step S901; Yes), the information providing server 9 determines whether or not the identification information Di corresponding to the auxiliary information B matches the identification information Ti of the subject terminal 8 (step S902). For example, the information providing server 9 receives the identification information Ti along with the provision request from the subject terminal 8, and determines whether or not the received identification information Ti matches the identification information Di. Alternatively, the information providing server 9 may determine that the identification information Ti matches the identification information Di when it acquires a signal indicating authentication from the subject terminal 8. In this case, when the identification information Di acquired in response to reading the two-dimensional barcode matches the identification information Ti, the subject terminal 8 transmits a signal indicating authentication to the information providing server 9 together with the provision request.

[0064] If the identification information Di and the identification information Ti match (step S902; Yes), the information providing server 9 transmits the auxiliary information B to the subject terminal 8 (step S903).

[0065] If the identification information Di and the identification information Ti do not match (step S902; No), the information providing server 9 executes error notification by transmitting an error signal indicating an error to the subject terminal 8 (step S904). In response to receiving the error signal, an error message such as "ID does not match" or "Data transmission is not permitted" is displayed on the display unit 84 of the subject terminal 8.

[0066] After executing step S903, after executing step S904, or if step S901 is No, the information providing server 9 determines whether the deletion condition for the auxiliary information B is met (step S905). The deletion condition includes the completion of transmission of the auxiliary information B to the subject terminal 8 and the lapse of a predetermined period of time since the two-dimensional code was generated. For example, the information providing server 9 determines that the deletion condition is met when it receives a signal from the subject terminal 8 indicating that the download of the auxiliary information B is complete. Furthermore, the information providing server 9 determines that the deletion condition is met when it receives a signal indicating a timeout from the subject terminal 8 that has acquired a timestamp indicating the generation time of the two-dimensional code. The period from the generation time of the two-dimensional code to the timeout can be set arbitrarily, but from the viewpoint of information security, it should be a relatively short period of time, such as two or five minutes.

[0067] If the deletion condition for auxiliary information B is not met (step S905; No), the information providing server 9 returns to step S901 and executes the process. On the other hand, if the deletion condition for auxiliary information B is met (step S905; Yes), the information providing server 9 deletes the auxiliary information B that it received from the report server 6 and stored (step S906). For example, in step S906, the CPU of the information providing server 9 immediately deletes the auxiliary information B stored in the storage device of the information providing server 9. The CPU may also delete data related to auxiliary information B that is temporarily stored in the RAM of the information providing server 9.

[0068] As described above, when a predetermined period of time has elapsed since the two-dimensional code was generated, the auxiliary information B is also deleted from the information providing server 9. In this case, the medical terminal 5 may cause the report server 6 to newly transmit the auxiliary information B to the information providing server 9 when a new two-dimensional code is generated in response to an instruction input by a medical professional.

[0069] Following step S906, the information providing server 9 determines whether or not there is any remaining auxiliary information B in the storage device (step S907). If there is any remaining auxiliary information B (step S907; No), the information providing server 9 repeats step S906 until there is no remaining auxiliary information B (step S907; Yes). Then, when there is no remaining auxiliary information B (step S907; Yes), the information providing server 9 ends the auxiliary information providing process.

[0070] The series of operations required to execute the auxiliary information provision process is designed to be performed quickly and in front of the medical professional, with the subject (patient) in the same examination room as the medical professional. If there is data corruption or a transmission / reception error, the medical professional can confirm the failure on the spot and can present the two-dimensional code by operating the medical terminal 5 again. This completes the auxiliary information provision process.

[0071] Next, an auxiliary report information generation process for generating auxiliary report information Ts showing auxiliary report image S (see FIG. 9) based on auxiliary information B received by the subject terminal 8 will be described with reference to FIG. 8. The auxiliary report image S is displayed on the subject terminal 8 to help the subject (patient) understand the treatment progress and treatment plan regarding VA.

[0072] The control unit 80 of the subject terminal 8 executes the auxiliary report information generation process in accordance with the dedicated application described above. The auxiliary report information generation process is started, for example, when the subject terminal 8 receives the auxiliary information B from the information providing server 9 and stores it in the storage unit 81.

[0073] (Auxiliary report information generation process) When the control unit 80 starts the auxiliary report information generation process, the reference value calculation unit 80a calculates a blood flow reference value based on the VA detailed information B3 included in the auxiliary information B (step S801). The blood flow reference value indicates, for example, a range of FV considered normal. The storage unit 81 pre-stores reference value calculation data (not shown) for calculating the blood flow reference value according to the VA type and VA position indicated by the VA detailed information B3. The reference value calculation unit 80a calculates the blood flow reference value based on the VA type, VA position, and the reference value calculation data. For example, the reference value calculation data may be composed of (i) table data in which the VA type, VA position, and the blood flow reference value to be calculated are associated with each other, and (ii) an algorithm for outputting the blood flow reference value in response to the input of the VA type and VA position. The blood flow reference value may be a range of RI considered normal. Alternatively, the reference value calculation unit 80a may calculate both a range of FV and a range of RI considered normal. In the following description, the blood flow reference value indicates a range of FV.

[0074] Next, the control unit 80 generates evaluation target information based on the blood vessel evaluation information B1 and progress information B2 included in the auxiliary information B using the function of the state evaluation unit 80b (step S802). The evaluation target information is data for evaluating the state of blood vessels, as well as data for visualizing, for example, time-series information on the date of ultrasound examination and the date of treatment. In the auxiliary report image S (see FIG. 9) displayed as described below, a line graph showing the FV value for each examination date and an icon indicating the date of treatment (in the illustrated example, the location marked PTA) are displayed based on the evaluation target information. The state evaluation unit 80b also calculates the amount of change in FV between the previous examination and the current examination. Furthermore, the state evaluation unit 80b also calculates the period elapsed from the date of the previous treatment to the present. The calculated amount of change in FV and the period elapsed are also included in the evaluation target information.

[0075] Next, the condition evaluation unit 80b determines the vascular condition of the subject patient based on the blood flow reference value calculated by the reference value calculation unit 80a in step S801 and the determination target information generated in step S802 (step S803). For example, the condition evaluation unit 80b evaluates the vascular condition in stages, such as "no abnormality," "mild occlusion risk," "moderate occlusion risk," and "severe occlusion risk," depending on the current FV value relative to the median of the blood flow reference value (e.g., the range of reference FVs). Such stage evaluations are set so that the condition evaluation unit 80b evaluates the vascular condition as being higher the further the current FV value falls below the median of the blood flow reference value.

[0076] The condition evaluation unit 80b can also evaluate whether the upcoming treatment is eligible for insurance coverage based on the time elapsed since the previous treatment. For example, the condition evaluation unit 80b can evaluate the eligibility of the upcoming treatment for insurance coverage in stages, such as "not eligible," "likely eligible," or "eligible," based on the time elapsed since the previous treatment. For example, the condition evaluation unit 80b evaluates the eligibility of insurance coverage as follows: (i) if more than three months have passed since the previous treatment, the condition is evaluated as "eligible," (ii) if more than three months have passed since the previous treatment but the blood flow conditions meet the conditions for additional treatment, the condition is evaluated as "likely eligible," and (iii) if more than three months have passed since the previous treatment and the conditions for additional treatment are not met, the condition is evaluated as "not eligible." The algorithm for evaluating the eligibility of insurance coverage may be incorporated into a program for executing the auxiliary report information generation process and stored in the storage unit 81. In addition, if the criteria for eligibility for insurance treatment are changed, the algorithm for evaluating the possibility of eligibility for insurance treatment can be modified to take into account the changed criteria for eligibility for insurance treatment by updating the program for executing the auxiliary report information generation process.

[0077] Next, the control unit 80 uses the function of the auxiliary report generation unit 80c to generate auxiliary report information Ts indicating an auxiliary report image S as shown in FIG. 9, which visualizes the evaluation results of the blood vessel state, the evaluation results of insurance treatment eligibility, the FV value for each examination date, the treatment date, etc. (step S804), and stores the auxiliary report information Ts in the storage unit 81. Then, the control unit 80 displays the auxiliary report image S on the display unit 84. Note that the state evaluation unit 80b may evaluate the blood vessel state based on RI, or may evaluate the blood vessel state using both FV and RI. This completes the auxiliary report information generation process.

[0078] Within the dedicated network N1, a dedicated NTP (Network Time Protocol) server (not shown) is provided for the medical institution 2, and timestamps of the image server 4, medical terminal 5, report server 6, etc. are synchronized by this dedicated NTP server. Using this timestamp, data is transmitted from the image server 4 to the medical terminal 5, and from the medical terminal 5 to the information providing server 9 via the report server 6. Meanwhile, the public network N2 is connected to the Internet, and the timestamp of the information providing server 9 provided within the public network N2 is synchronized by an NTP server that transmits the current time over the Internet. This allows auxiliary information B to be safely transmitted from the medical terminal 5 to the subject terminal 8 via the report server 6 and the information providing server 9.

[0079] The present invention is not limited to the above-described embodiments, modifications, and drawings. Appropriate modifications (including omission of components) can be made to the embodiments without departing from the spirit of the present invention.

[0080] (Variation) Although the above examples show a case where the subject is a patient, the subject may also be a sick animal. That is, the VA mapping system 1 may be used in a veterinary hospital as the medical institution 2. Furthermore, the part of the subject on which the VA is provided is not limited to the arm, but may be any part such as the leg.

[0081] The medical terminal 5 is not limited to a tablet terminal, but may be a notebook PC (Personal Computer) or a desktop PC used in a consultation room. These PCs may be equipped with a touch panel 5T, or the input unit 53 and the display unit 54 may be configured separately. In this case, the input unit 53 may be a pointing device such as a mouse or a touchpad. The imaging unit 52 is not limited to being built into the PC, but may be a digital camera connected to the PC. The subject terminal 8 may be a tablet terminal as long as it is carried by the subject or a person related to the subject.

[0082] Although the above describes an example in which the subject terminal 8 generates auxiliary report information Ts and displays an auxiliary report image S, the medical terminal 5 may also be capable of displaying the auxiliary report image S. That is, the control unit 50 of the medical terminal 5 may further include the functions of a reference value calculation unit 80a, a state evaluation unit 80b, and an auxiliary report generation unit 80c, and may generate auxiliary report information Ts using a procedure similar to that described above. The auxiliary report image S may then be displayed on the display unit 54 of the medical terminal 5. The auxiliary report image S displayed on the medical terminal 5 may be presented to a patient or the like in the examination room to help them understand the treatment progress and treatment plan related to VA. Furthermore, the auxiliary report information Ts generated by the medical terminal 5 may be stored in the report server 6, and the auxiliary report information Ts may be provided to the subject terminal 8 using a procedure similar to that of the auxiliary information provision process described above.

[0083] The auxiliary information B provided to the subject terminal 8 may include at least the blood vessel evaluation information B1 and the progress information B2. For example, in step S801, the reference value calculation unit 80a of the subject terminal 8 may calculate a predetermined standard blood flow reference value without using the VA detailed information B3. Furthermore, the auxiliary information B provided to the subject terminal 8 may be at least a part of the VA information Dv, as long as it includes the blood vessel evaluation information B1 and the progress information B2. For example, the auxiliary information B may include ultrasound image information Gu, functional test image information Gf, etc. Furthermore, the auxiliary information B provided to the subject terminal 8 may include report information Dr. The VA map R may also be viewable on the subject terminal 8. Furthermore, the auxiliary information B may be the entire VA information Dv.

[0084] In the above, an example has been shown in which the image server 4 and the report server 6 are separately provided within the medical institution 2, but the report server 6 may also have the functions of the image server 4. In other words, the report server 6 may directly receive various data from the ultrasound examination device 3. Of course, each component of the VA mapping system 1 may be provided in plurality. For example, the correspondence between one of the ultrasound examination device 3 and the medical terminal 5, which can communicate with each other via the dedicated network N1, may be one-to-many or many-to-many.

[0085] In the above, an example has been shown in which the subject terminal 8 receives the auxiliary information B via a communication path that goes in the order of the medical terminal 5, the report server 6, the one-way communication cable 9a, and the information providing server 9. However, as long as security can be ensured, the communication path through which the subject terminal 8 receives the auxiliary information B can be arbitrarily designed. Below, modified examples of the communication path will be described.

[0086] For example, the report server 6 may store the auxiliary information B in external storage in the cloud for a certain period of time, and the information providing server 9 may receive the auxiliary information B from the external storage.

[0087] For example, the auxiliary information B may be stored for a certain period of time in external storage via the cloud from the medical terminal 5 or the report server 6, and the subject terminal 8 may receive the auxiliary information B from the external storage. In this case, for example, a two-dimensional code for permitting access to the external storage may be displayed on the medical terminal 5, and the subject terminal 8 may read the two-dimensional code to download the auxiliary information B from the external storage.

[0088] The auxiliary report image S is not limited to a form using a graph as exemplified in Fig. 9, and may be configured as a table using text data. Furthermore, at least a part of the VA information Dv, at least a part of the report information Dr, at least a part of the auxiliary report information Ts, etc. may be displayed on the subject terminal 8 by reading a two-dimensional code displayed on an image output from the medical terminal 5 or the printer 7 with the subject terminal 8.

[0089] The medical terminal 5 or the report server 6 may be able to provide report information Dr, VA information Dv, etc. indicating the VA map R to other medical institutions that use the VA mapping system 1 via the cloud.

[0090] The condition evaluation unit 80b may use a learning model that has been subjected to machine learning. For example, the learning model can be constructed by performing machine learning using a known mathematical model such as a neural network, with FV, RI, the amount of change in FV, the amount of change in RI, etc. as explanatory variables and stages indicating the state of the blood vessels as labels. This can improve the accuracy of the evaluation of the state of the blood vessels.

[0091] The programs for executing the above-described processes may be distributed or provided on a removable recording medium. The programs may also be downloaded from other devices connected to the device on which the programs are to be executed. The device on which the programs are to be executed may execute the processes according to the programs by exchanging various data with the other devices via a telecommunications network or the like.

[0092] (effect) The effects achieved by the VA mapping system 1 described above will be explained below.

[0093] (1) The VA mapping system 1 includes an ultrasound examination device 3, a medical terminal 5, and a report server 6 that communicates with the medical terminal 5 via a dedicated network N1. The medical terminal 5 includes an imaging unit 52 (an example of imaging means), an information acquisition unit 50a (an example of information acquisition means), a display unit 54 (an example of display means), an input unit 53 (an example of input means), and a VA information generation unit 50b (an example of generation means). The VA information generation unit 50b generates VA information Dv, which includes the photographed image information Gp, ultrasound image information Gf, and vascular evaluation information B1 acquired by the information acquisition unit 50a, and the vascular map information A1 and position information A2 input from the input unit 53, in which the position information A2 is associated with the ultrasound image information Gu. Based on the VA information Dv, the VA information generation unit 50b further generates report information Dr indicating a VA map R, which is an image in which the vascular map information A1, position information A2, and vascular evaluation information B1 are superimposed on the photographed image P. The display unit 54 is capable of displaying a VA map R, and when a specified input is made using the input unit 53 for the display position of the position information A2 in the VA map R, an ultrasound image U indicated by the ultrasound image information Gu corresponding to the position information A2 is displayed in a pop-up. The report server 6 receives the report information Dr from the medical terminal 5 and stores it.

[0094] According to the configuration (1) above, the VA map R can be easily created by operating the medical terminal 5. In addition, since it is only necessary to install a program in the medical terminal 5, it can be easily introduced to the medical institution 2. Furthermore, by accessing the report server 6 from an in-hospital terminal that can connect to the dedicated network N1 of the medical institution 2, medical personnel can view the formatted VA map R, which allows for the sharing of VA map information. Furthermore, the following effects are also expected. The simple, concise and clear system shortens the time required to create VA maps, reducing the loss of medical personnel resources. Early detection and treatment of lesions can prevent VA obstruction. - When claiming medical insurance costs, objective evidence (evidence of medical examination images) can be left behind, preventing fraudulent claims for medical insurance.

[0095] (2) The VA information Dv generated by the VA information generating unit 50b includes functional test image information Gf associated with the vascular evaluation information B1, and when a designated input is made using the input unit 53 for the display position of the vascular evaluation information B1 in the VA map R, the display unit 54 may display a pop-up of the functional test image F indicated by the functional test image information Gf corresponding to the vascular evaluation information B1.

[0096] According to the above configuration (2), not only the ultrasound image U but also the functional test image F can be easily viewed from the VA map R displayed on the medical terminal 5.

[0097] (3) The VA mapping system 1 may further include a subject terminal 8. In this case, the VA information Dv generated by the VA information generating unit 50b includes progress information B2, and at least the blood vessel evaluation information B1 and progress information B2 of the VA information Dv are auxiliary information B that can be provided to the subject terminal 8. The report server 6 receives the auxiliary information B from the medical terminal 5 and stores it. The subject terminal 8 can receive auxiliary information B from the medical terminal 5 or the report server 6 via a predetermined communication path, evaluate the condition of the blood vessels based on the received auxiliary information B1, and display an auxiliary report image S showing the evaluation results.

[0098] According to the above configuration (3), it is possible to share information with patients and also to educate them.

[0099] (4) The report server 6 receives and stores the subject's identification information Di associated with the auxiliary information B from the medical terminal 5, and the VA mapping system 1 may further include an information providing server 9 that receives and stores the auxiliary information B and the subject's identification information Di from the report server 6 via one-way communication. In this case, the subject terminal 8 stores the subject's identification information Ti. The information providing server 9 transmits the auxiliary information B to the subject terminal 8 when a request for providing the auxiliary information B is received from the subject terminal 8 and when the subject identification information Di associated with the auxiliary information B matches the subject identification information Ti stored in the subject terminal 8. Furthermore, when predetermined conditions for deleting the auxiliary information B are met, the information providing server 9 deletes the stored auxiliary information B and the subject identification information Di, and the deletion conditions include completion of the transmission of the auxiliary information B to the subject terminal 8.

[0100] According to the above configuration (4), simply by providing the information providing server 9 in the medical institution 2, it is possible to provide the auxiliary information B to the subject terminal 8 while preventing leakage of personal information outside the hospital. Furthermore, once the auxiliary information B is provided to the subject terminal 8, the auxiliary information B and the subject's identification information Di are immediately deleted from the information providing server 9, which makes it possible to more effectively prevent leakage of personal information outside the hospital.

[0101] (5) The medical terminal 5 may generate a two-dimensional code for permitting access to the information providing server 9. In this case, the subject terminal 8 makes a request to the information providing server 9 in response to reading the two-dimensional code generated by the medical terminal 5, and the deletion condition includes the lapse of a predetermined period of time since the two-dimensional code was generated.

[0102] According to the configuration (5) above, patients carrying the subject terminal 8 can access the information providing server 9 with simple operations, and leakage of personal information outside the hospital can be more effectively prevented.

[0103] (6) The VA information generating unit 50b may evaluate the state of the blood vessels based on at least the blood vessel evaluation information B1 and the progress information B2 of the VA information Dv, and generate auxiliary report information Ts indicating an auxiliary report image S showing the evaluation result. In this case, the display unit 54 can display the auxiliary report image S indicated by the auxiliary report information Ts.

[0104] According to the above configuration (6), by presenting the auxiliary report image S displayed on the medical terminal 5 to the patient in the examination room, it is possible to help the patient understand the treatment progress and treatment plan regarding VA.

[0105] (7) The medical terminal 5 may be a tablet terminal, and the display unit 54 and the input unit 53 may be realized by a touch panel 5T of the tablet terminal.

[0106] According to the above configuration (7), it is easy for medical personnel to carry, and input operations such as vascular map information A1 and position information A2 are also easy.

[0107] In the above description, in order to facilitate understanding of the present invention, descriptions of well-known technical matters have been omitted as appropriate.

[0108] This invention allows various embodiments and modifications without departing from the broad spirit and scope of this invention. Furthermore, the above-described embodiments are intended to explain this invention and do not limit the scope of this invention. That is, the scope of this invention is defined by the claims, not the embodiments. Various modifications made within the scope of the claims and the meaning of the invention equivalent thereto are considered to be within the scope of this invention. [Explanation of symbols]
