Patient DB 22a shown in FIG. 3A includes a patient ID column, a physical data column, a measurement data column, and the like. The patient ID column stores identification information (patient ID, patient code) for identifying each patient. The patient ID may be, for example, the patient card number of a patient card issued by a medical institution. The physical data column stores the patient's physical data in association with the patient ID. The physical data includes the patient's age, sex, height, and weight, and values ​​input via input unit 24, for example, are stored. The measurement data column stores the patient's measurement data measured using body composition analyzer 20 in association with the patient ID. Only the most recent data is overwritten and saved for the physical data. Only the most recent data may be overwritten and saved for the measurement data, or each data may be stored in association with the measurement date and time. The measurement data includes the measurement date and time, bioelectrical impedance, and body composition information calculated from the bioelectrical impedance and physical data. The body composition information includes, for example, fat-free mass (FFM), fat mass, body fat percentage, FFMI (Fat Free Mass Index), phase angle (PhA), total body water (TBW), extracellular water (ECW), intracellular water (ICW), hydration rate, extracellular water ratio (edema index), muscle mass, and intracellular water ratio. , external fluid ratio, internal fluid / external fluid ratio, etc. Each piece of body composition information is calculated and stored by the control unit 21 according to a program and calculation formula stored in the storage unit 22.

[0047] Fat-free mass (FFM) is calculated using a formula that uses height and bioelectrical impedance, for example, prepared for each combination of age, sex, and body weight (weight range). Fat mass is calculated using a formula that subtracts fat-free mass from body weight (body weight - fat-free mass). Body fat percentage is calculated using a formula that divides fat mass by body weight (fat mass / body weight). FFMI is calculated using a formula that divides fat-free mass by the square of height (fat-free mass / (height * height)). Extracellular fluid volume (ECW) and intracellular fluid volume (ICW) are calculated using a formula that uses height, body weight, and bioelectrical impedance, for example, prepared for each gender. Total body water (TBW) is calculated using a formula that adds extracellular fluid volume and intracellular fluid volume (ECW + ICF). The hydration rate is calculated using the formula (TBW / FFM) that divides total body water by fat-free mass, and the extracellular water ratio (edema rate) is calculated using the formula (ECW / TBW) that divides extracellular fluid by total body water. The intracellular fluid ratio is calculated using the formula (ICW / FFM) that divides intracellular fluid by fat-free mass, the extracellular fluid ratio is calculated using the formula (ECW / FFM) that divides extracellular fluid by fat-free mass, and the intracellular / external fluid ratio is calculated using the formula (ICW / ECW) that divides intracellular fluid by extracellular fluid. The formulas for calculating each piece of body composition information are not limited to the examples described above. In addition to the above, other body composition information may include skeletal muscle mass, SMI (Skeletal Muscle Index), muscle mass, bone mineral content (estimated bone mass), protein content, and basal metabolic rate. etc.

The patient DB 12a shown in FIG. 3B includes a patient ID column, a name column, a data ID column, a measurement / recalculation column, a date and time column, a bioelectrical impedance column, a body data column, a body composition information column, etc. The patient ID column contains identification information (patient ID, patient code) for identifying each patient. The patient ID may be the patient card number of a patient card issued by a medical institution. If the patient ID is the same as the patient ID stored in the patient DB 22a of the body composition analyzer 20, the patient ID can be used to associate the user of the body composition analyzer 20 with a patient at the medical institution. The name column stores the patient's name in association with the patient ID. The data ID column stores identification information (data ID) assigned to each set of body composition information stored in the patient DB 12a. The measurement / recalculation column stores information indicating whether the corresponding body composition information is measurement data measured by the body composition analyzer 20 or recalculated data recalculated by the information processing device 10. Specifically, if the data is measurement data, "measurement" is stored, and if the data is recalculated data, "recalculation" is stored. The date and time column stores the date and time of measurement of the bioelectrical impedance by the body composition analyzer 20, and the bioelectrical impedance column stores the bioelectrical impedance measured by the body composition analyzer 20. The body data column stores the body data used to calculate the corresponding body composition information, and the body composition information column stores information on body composition calculated from bioelectrical impedance and the body data. The body composition information stored in the body composition information column may include the same type of information as the body composition information (body composition information measurable by the body composition analyzer 20) stored in the patient DB 22a of the body composition analyzer 20, and may also include different types of information. The patient DB 12a is not limited to the configuration shown in FIG. 3B. For example, body composition information that is recalculated data may be stored with marking information indicating that it is different from body composition information that is measurement data. The measurement / recalculation column may be configured to store "recalculation" only when the body composition information is recalculated data. The marking information may include letters or symbols indicating "recalculation," or a mark indicating whether or not a recalculation has occurred. Furthermore, the marking information may include a different background color for data corresponding to "recalculation," a different font, color, or thickness for the results corresponding to "recalculation," or a flashing display.

[0049] The following describes the process of presenting body composition information of each patient measured by body composition analyzer 20 to a medical professional via information processing device 10. Fig. 4 is a flowchart showing an example of the body composition information display process procedure, and Figs. 5 to 7 are explanatory diagrams showing example screens. In Fig. 4, the left side shows the process performed by control unit 21 of body composition analyzer 20, and the right side shows the process performed by control unit 11 of information processing device 10.

[0050] For example, a medical professional may measure a patient's body composition information using body composition monitor 20, and then communicatively connect body composition monitor 20 and information processing device 10 to transmit the patient ID, physical data, and measurement data of each patient stored in patient DB 22a of body composition monitor 20 to information processing device 10. Note that the instruction to transmit data from body composition monitor 20 to information processing device 10 may be received via input unit 24 of body composition monitor 20 or via input unit 14 of information processing device 10. The medical professional may also specify a patient and issue an instruction to transmit the data of the specified patient from body composition monitor 20 to information processing device 10, or may issue an instruction to transmit the data of all patients stored in patient DB 22a from body composition monitor 20 to information processing device 10.

[0051] When the control unit 21 of the body composition monitor 20 receives an instruction to transmit data to the information processing device 10, it determines whether it is able to communicate with the information processing device 10 and whether it is able to transmit data stored in the patient DB 22a to the information processing device 10 (S11). If it determines that transmission is not possible (S11: NO), the control unit 21 waits until it determines that transmission is possible. If it determines that transmission is possible (S11: YES), the control unit 21 transmits the patient ID, physical data, and measurement data stored in the patient DB 22a to the information processing device 10 (S12). If a patient is specified, the control unit 21 transmits the patient ID, physical data, and measurement data of the specified patient to the information processing device 10. If it is instructed to transmit data for all patients, the control unit 21 transmits the patient IDs, physical data, and measurement data of all patients stored in the patient DB 22a to the information processing device 10.

[0052] When the control unit 11 of the information processing device 10 receives data from the body composition analyzer 20, it issues a data ID and stores the issued data ID, the date and time and bioelectrical impedance included in the received measurement data, the received physical data (first physical data recorded on the body composition analyzer 20), and the body composition information (first body composition information) included in the received measurement data in association with the received patient ID in the patient DB 12a (S13). Here, since the body composition information stored in the patient DB 12a is data measured by the body composition analyzer 20, the control unit 11 stores "measurement" in the measurement / recalculation column. The control unit 11 stores the received data of all patients in the patient DB 12a.

[0053] The control unit 11 determines whether an instruction to view the body composition information of each patient stored in the patient DB 12a has been received via the input unit 14 (S14). If it determines that the instruction has not been received (S14: NO), the control unit 11 terminates the process. If it determines that the instruction to view the body composition information has been received (S14: YES), the control unit 11 displays a list screen of patients registered in the patient DB 12a on the display unit 15 (S15). FIG. 5A shows an example of the patient list screen. The screen shown in FIG. 5A displays each patient's patient ID, name, physical data (gender, age, height, weight), bioelectrical impedance, measurement mode of the body composition analyzer 20, and measurement date and time of the body composition information in association with each other as a single record data. This information is read from the patient DB 12a and displayed on the patient list screen. Note that if body composition information for a single patient with different measurement dates and times is stored in the patient DB 12a, multiple record data for that patient are displayed. The patient list screen may also be configured to display each patient's body composition information in addition to the configuration of FIG. 5A. When a predetermined operation (e.g., right-clicking the mouse) is performed on one record data, the patient list screen displays an operation menu for accepting an instruction to recalculate the body composition information of the patient of the record data selected by the predetermined operation, as shown in Figure 5A.

[0054] Control unit 11 determines whether an instruction to recalculate the body composition information of the patient of record data selected by a predetermined operation has been received via the operation menu shown in FIG. 5A (S16). If it determines that an instruction to recalculate has been received (S16: YES), control unit 11 acquires from patient DB 12a the physical data and bioelectrical impedance (data of the selected measurement date and time) corresponding to the patient and measurement date and time of the selected record data (S17). Then, control unit 11 displays a physical data reception screen as shown in FIG. 5B on display unit 15 based on the acquired physical data (S18). The screen of FIG. 5B displays the name and measurement date and time of the patient of record data selected via the screen of FIG. 5A. The screen of FIG. 5B also has input fields for physical data (age, sex, height, weight), and each input field displays the physical data (age, sex, height, weight) acquired in step S17. Each input field for physical data is configured to allow the displayed data to be modified (changed), and control unit 11 accepts a modification (change instruction) of the physical data via input unit 14 (S19). When control unit 11 receives the correction, it displays the corrected (changed) physical data (latest physical data) in each input field.

[0055] The screen of Fig. 5B is provided with an OK button for instructing the execution of recalculation of body composition information using the physical data displayed in each input field, and control unit 11 determines whether or not the OK button has been operated (S20). If it is determined that the OK button has not been operated (S20: NO), for example, if the cancel button on the screen of Fig. 5B has been operated, control unit 11 returns to step S15 and returns to the display of the patient list screen shown in Fig. 5A. If it is determined that the OK button has been operated on the screen of Fig. 5B (S20: YES), control unit 11 calculates (recalculates) body composition information (second body composition information) of the selected patient using the physical data displayed in each input field on the screen of Fig. 5B (corrected physical data, second physical data) and the bioelectrical impedance acquired in step S17 (bioelectrical impedance measured by body composition analyzer 20 at the selected measurement date and time) (S21). The process of calculating each value of the body composition from the body data and bioelectrical impedance can be the same process as the calculation process performed by the body composition analyzer 20, and the control unit 11 can calculate the body composition information related to the same type of body composition as the body composition information measured by the body composition analyzer 20. Calculate the numerical value.

[0056] Then, the control unit 11 stores the body composition information (second body composition information) obtained by recalculation in the patient DB 12a in association with the measurement date and time selected here (the same date and time as the measurement date and time linked to the first body composition information) (S22). Specifically, the control unit 11 issues a data ID and stores the issued data ID, the selected measurement date and time, the bioelectrical impedance and body data (second body data) acquired in step S17, and the recalculated body composition information in association with the patient ID of the patient selected here in the patient DB 12a. Furthermore, since the body composition information stored in the patient DB 12a here is data recalculated by the information processing device 10, the control unit 11 stores "recalculation" in the measurement / recalculation column. This allows the body composition information obtained by recalculation to be stored in association with the measurement date and time of the bioelectrical impedance used to recalculate the body composition information. In other words, body composition information calculated using the same bioelectrical impedance and corrected physical data (body composition information measured by the body composition analyzer 20 and body composition information recalculated by the information processing device 10) can be stored in the patient DB 12a as different data and associated with the same patient ID.

[0057] The control unit 11 returns to step S15 and returns to displaying the patient list screen. Since the recalculated body composition information has been stored in the patient DB 12a, the control unit 11 displays the patient list screen as shown in FIG. 5C. The screen in FIG. 5C has the same configuration as FIG. 5A, but displays record data A1 of body composition information measured by body composition analyzer 20 and record data A2 of body composition information obtained by recalculation side by side (continuously) as information on the measurement date and time "2023 / 2 / 4 11:00:00" of the patient with patient ID [A0011]. Record data A2 of the body composition information obtained by recalculation is given a mark M (indicator) indicating that the body composition information is recalculated data. This configuration allows the user to determine whether each record data displayed on the patient list screen is record data of body composition information measured by body composition analyzer 20 or record data of body composition information recalculated by the information processing device 10. The weight of record data A2 is displayed as the corrected weight (here, 40).

[0058] The patient list screens shown in Figures 5A and 5C are configured to accept selection of the patient of record data for which a predetermined operation (e.g., double-clicking the mouse) has been performed on one record data. If the control unit 11 determines that an instruction to execute recalculation has not been received (S16: NO), it determines whether or not a selection of an arbitrary patient has been received on the patient list screen through a predetermined operation (S23). If it determines that a selection of an arbitrary patient has not been received (S23: NO), it terminates the processing. If it determines that a selection of an arbitrary patient has been received (S23: YES), the control unit 11 generates a details screen displaying body composition information of the selected patient (S24), as shown in Figures 6A to 7, and displays the generated details screen on the display unit 15 (S25).

[0059] The details screen has a "Summary" tab, a "Body Composition" tab, and an "Impedance" tab, and by switching the tab selection, a screen corresponding to the selected tab is displayed. When the "Summary" tab is selected, the screen shown in FIG. 6A is displayed. When the "Body Composition" tab is selected, the screen shown in FIG. 6B is displayed. When the "Impedance" tab is selected, the screen shown in FIG. 7 is displayed. When the screen of FIG. 6A is displayed, the control unit 11 reads from the patient DB 12a, among the body composition information of the patient selected via the patient list screen, the body composition information corresponding to the measurement date and time of the record data selected via the patient list screen (current information), the body composition information corresponding to the measurement date and time immediately before this measurement date and time (previous information), and the body composition information corresponding to the measurement date and time to be used as a comparison standard when observing changes in the body composition information (base information). Note that the base information may be, for example, information at the time of admission if the patient is an inpatient, or information at the time of discharge if the patient has been discharged, or information at the time some treatment was started. In addition, the previous information or the base information may be information corresponding to the patient's If the body composition information of the measurement data and the body composition information of the recalculated data are stored in the patient DB 12a in association with the same measurement date and time for the three time points described above, the control unit 11 preferentially reads the body composition information of the recalculated data (second body composition information) from the patient DB 12a.

[0060] The control unit 11 generates a basic data column R1 that displays the read body composition information and physical data (height and weight) associated with the measurement date and time (measurement date and measurement time) for the three time points described above. The control unit 11 also extracts weight, fat mass, lean mass, total body water, intracellular fluid volume, and extracellular fluid volume for each of the three time points, generates a stacked graph displaying fat mass and lean mass, and a stacked graph displaying intracellular fluid volume and extracellular fluid volume, and generates a transition display column R2 that displays these graphs. This allows the control unit 11 to generate the screen shown in FIG. 6A. The measurement date and measurement time displayed in the basic data column R1 on the screen of FIG. 6A are displayed using a pull-down menu that allows the user to select any date and time from the measurement dates and times for the patient's body composition information that has already been measured. When a different measurement date and measurement time are selected via the pull-down menu, the control unit 11 reads out body composition information corresponding to the selected measurement date and time (multiple measurement dates and times) from the patient DB 12a and updates the display contents of the basic data column R1 and the transition display column R2.

[0061] When displaying the screen of FIG. 6B, the control unit 11 reads out the body weight, fat mass, and fat-free mass of the selected patient's body composition information from the patient DB 12a. For example, the control unit 11 reads out the body weight, fat mass, and fat-free mass corresponding to the measurement date and time of the record data selected via the screen of FIG. 5A or FIG. 5C, or a predetermined number of measurement dates and times going back from the current measurement date and time selected via the pull-down menu on the screen of FIG. 6A. In the example of FIG. 6B, 11 graphs are displayed, so the body weights, fat masses, and fat-free masses corresponding to the 11 measurement dates and times are read out. Here, too, if the patient DB 12a stores body composition information of the measurement data and body composition information of the recalculated data in association with the same measurement date and time, the control unit 11 preferentially reads out the body composition information of the recalculated data (second body composition information) from the patient DB 12a. The control unit 11 generates a stacked graph displaying the fat mass and fat-free mass for each measurement date and time, and generates a weight transition column R3 in which the generated graphs are displayed in chronological order. This creates a graph showing time-series changes in the patient's body composition (here, fat mass and lean mass). If normal ranges for each piece of body composition information, such as standard values ​​(normal ranges) for lean mass, are stored in the memory unit 12, the control unit 11 adds a mark indicating the normal range to the created graph. In FIG. 6B, the standard values ​​(normal ranges) for lean mass are shown with a gray background. This allows the control unit 11 to create the screen shown in FIG. 6B.

[0062] When displaying the screen of Fig. 7, the control unit 11 generates an impedance column R4 and a Cole-Cole plot column R5 that display the read bioelectrical impedance in association with the measurement date and time (measurement date and measurement time) for the three time points selected in Fig. 6A. The control unit 11 reads out the bioelectrical impedance of the selected patient from the patient DB 12a. This allows the control unit 11 to generate the screen shown in FIG. 7. Note that the measurement date and measurement time displayed in the impedance field R4 on the screen of FIG. 7 are provided with a pull-down menu for selecting any date and time from the measurement dates and times of body composition information that has already been measured for that patient. When another measurement date and measurement time are selected via the pull-down menu, the control unit 11 reads out body composition information corresponding to the selected measurement date and time (multiple measurement dates and times) from the patient DB 12a, and updates the display contents of the impedance field R4 and the Cole-Cole plot field R5.

[0063] By the above-described process, the body composition information (measurement data) calculated by the body composition analyzer 20 based on the same bioelectrical impedance and the body composition information (recalculated data) recalculated by the information processing device 10 are linked to the same measurement date and time and stored in the patient DB 12a. Body composition information (measurement data and recalculated data) calculated based on electrical impedance and different physical data can be managed using the same measurement date and time and the same patient ID. This allows for the creation of graphs (Figures 6A and 6B) showing changes in body composition information over time for a specific patient. When measurement data and recalculated data are available for the same measurement date and time, either one (e.g., the recalculated data) can be used. Recalculating body composition information using the latest physical data makes it possible to obtain optimal body composition information for each measurement date and time. Therefore, by creating graphs showing changes in body composition information over time using such body composition information, more appropriate changes in body composition information over time can be presented.

[0064] In the above-described process, for example, after the process of step S22, the control unit 11 may transmit the body composition information stored in the patient DB 12a to the electronic medical record server 30 and register it in the electronic medical record DB 32a. In this case, the body composition information recalculated using the latest physical data can be registered in the electronic medical record DB 32a.

[0065] (Embodiment 2) In this embodiment, an information processing system will be described in which an information processing device 10 obtains the latest physical data of a patient from an electronic medical record server 30, and then presents appropriate body composition information for the patient using the latest physical data. The information processing system of this embodiment can be realized by devices 10, 20, and 30 similar to the information processing system of embodiment 1 shown in Figures 1 and 2, and therefore a description of the configuration of each device 10, 20, and 30 will be omitted.

[0066] Fig. 8 is a flowchart showing an example of the body composition information display processing procedure in embodiment 2, and Fig. 9 is an explanatory diagram showing an example screen. The processing shown in Fig. 8 is the processing shown in Fig. 4 with steps S31 to S36 added instead of steps S14 to S25. Explanation of the same steps as in Fig. 4 will be omitted.

[0067] In the information processing system of this embodiment, after processing step S13, the control unit 11 of the information processing device 10 obtains from the electronic medical record server 30 the latest physical data (second physical data) of the patient whose information is stored in the patient DB 12a (S31). Specifically, the control unit 11 extracts the patient ID of the patient whose information is stored in the patient DB 12a in step S13, requests the electronic medical record server 30 for the physical data of the patient corresponding to the extracted patient ID, and obtains the data from the electronic medical record server 30. The electronic medical record server 30 stores the patient's physical data in association with the patient ID and the measurement date and time of the physical data in the electronic medical record DB 32a. Therefore, the control unit 31 of the electronic medical record server 30 reads the patient's physical data requested by the information processing device 10 and the measurement date and time of the physical data from the electronic medical record DB 32a and transmits them to the information processing device 10. In addition, control unit 11 of information processing device 10 may request physical data of the patient by transmitting the patient ID of the patient whose information was stored in patient DB 12a in step S13 and the measurement date and time of the measurement data stored in patient DB 12a to electronic medical record server 30. In this case, control unit 31 of electronic medical record server 30 identifies one piece of physical data (second physical data) of the patient stored in electronic medical record DB 32a, whose recording date and time (measurement date and time) of each piece of physical data is earlier than the measurement date and time requested by information processing device 10 and closest to the measurement date and time, reads it from electronic medical record DB 32a, and transmits it to information processing device 10.

[0068] When the control unit 11 of the information processing device 10 acquires the physical data and the measurement date and time of the patient from the electronic medical record server 30, it determines whether or not the physical data stored in the patient DB 12a in step S13 needs to be updated (S32). For example, the control unit 11 compares the measurement date and time of the measurement data stored in the patient DB 12a with the measurement date and time acquired from the electronic medical record server 30, and if the measurement date and time acquired from the electronic medical record server 30 is later, it determines that the physical data acquired from the electronic medical record server 30 is newer data and updates the physical data stored in the patient DB 12a. The control unit 11 determines that the physical data needs to be updated. On the other hand, if the measurement date and time acquired from the electronic medical record server 30 is earlier, the control unit 11 determines that the physical data acquired from the electronic medical record server 30 is older and that the physical data stored in the patient DB 12a does not need to be updated. Furthermore, if the control unit 11 has a recording date and time (measurement date and time) of the physical data stored in the patient DB 12a, it compares this recording date and time with the measurement date and time (recording date and time) associated with the physical data acquired from the electronic medical record server 30, and selects the one closest to the measurement date and time of the measurement data stored in the patient DB 12a in step S13. If the control unit 11 selects the physical data stored in the patient DB 12a, the control unit 11 determines that the physical data does not need to be updated (S32: NO) and terminates the process. In this case, the control unit 11 stores the body composition information measured by the body composition analyzer 20 (first body composition information) in the patient DB 12a, and does not update the physical data or recalculate the body composition information (second body composition information) using the updated physical data.

[0069] If the user selects physical data acquired from electronic medical record server 30, control unit 11 determines that the physical data needs to be updated (S32: YES) and updates (changes) the physical data (first physical data) stored in patient DB 12a based on the physical data (second physical data) acquired from electronic medical record server 30 (S33). This allows for acquisition of newer physical data (second physical data) than the physical data acquired from body composition analyzer 20. Control unit 11 calculates (recalculates) the body composition information (second body composition information) of the selected patient using the updated physical data and the bioelectrical impedance stored in patient DB 12a in step S13 (S34). Step S34 is the same process as step S21 in FIG. 4.

[0070] Then, the control unit 11 stores the recalculated body composition information in the patient DB 12a in association with the same date and time as the measurement date and time of the bioelectrical impedance stored in the patient DB 12a in step S13 (S35). Specifically, the control unit 11 issues a data ID and stores in the patient DB 12a the issued data ID, the measurement date and time of the bioelectrical impedance and the measurement value of the bioelectrical impedance stored in the patient DB 12a in step S13, the updated body data (second body data), and the recalculated body composition information (second body composition information) in association with the patient ID of the patient whose information is stored in the patient DB 12a. Here, the body composition information stored in the patient DB 12a is data recalculated by the information processing device 10, so the control unit 11 stores "recalculated" in the measurement / recalculation column. This allows the body composition information (second body composition information) recalculated using the latest physical data obtained from electronic medical record server 30 to be stored in association with the measurement date and time of the bioelectrical impedance used to recalculate the body composition information. If measurement data for multiple measurement dates and times is stored collectively in step S13, multiple pieces of second physical data corresponding to each measurement date and time are obtained from electronic medical record server 30 in the subsequent step S31. Thereafter, in step 32 and thereafter, the first physical data stored in patient DB 12a is compared with the second physical data obtained from electronic medical record server 30 for each measurement date and time (data ID), and a determination is made as to whether the physical data needs to be updated.

[0071] The control unit 11 generates a screen (alert information) such as that shown in FIG. 9 and displays it on the display unit 15, thereby notifying the user that new physical data (latest physical data) is available for the physical data acquired from the body composition monitor 20 (S36). The screen in FIG. 9 displays a message notifying the user that the weight, which is one of the physical data acquired from the body composition monitor 20, has been updated based on the physical data acquired from the electronic medical record server 30. This allows the user of the information processing device 10 to understand that the physical data of the patient registered in the body composition monitor 20 is old. Furthermore, by the user updating the physical data of the patient registered in the body composition monitor 20 to the latest physical data, it becomes possible to measure (calculate) appropriate body composition information based on the latest physical data in subsequent measurements with the body composition monitor 20. Note that the information processing device 10 and the body composition monitor 20 may be configured to transmit and receive information, and the control unit 11 of the information processing device 10 may be configured to transmit an instruction to the body composition monitor 20 to update to the latest physical data. In this case, the control unit 11 transmits the patient ID and physical data of the patient to be updated to the body composition monitor 20. The information processing device 10 transmits the patient ID to the electronic medical record server 30, instructing the body composition monitor 20 to update (overwrite) the physical data registered therein, and the control unit 21 of the body composition monitor 20 updates (overwrites) the physical data of the patient registered in the patient DB 22a in association with the received patient ID with the physical data received from the information processing device 10. With this configuration, the latest physical data acquired by the information processing device 10 from the electronic medical record server 30 can also be automatically registered in the body composition monitor 20.

[0072] If the control unit 11 stores information about multiple patients in the patient DB 12a in step S13, it executes steps S31 to S36 for all patients. As a result, when body composition information about multiple patients measured using the body composition analyzer 20 is acquired, it can determine whether the latest physical data is available for each acquired body composition information. If the latest physical data is available, it can recalculate the body composition information using the latest physical data, thereby acquiring appropriate body composition information for each patient. Furthermore, for the body composition information of a patient measured using the body composition analyzer 20, the control unit 11 can recalculate the body composition information using physical data measured on a date and time that is earlier than but closest to the measurement date and time of the body composition information. This allows it to acquire appropriate body composition information at the time of measurement of the body composition information. Furthermore, in this embodiment, for example, after processing step S34, the control unit 11 may transmit the body composition information stored in the patient DB 12a to the electronic medical record server 30 and register it in the electronic medical record DB 32a. In this case, the body composition information recalculated using the latest physical data can be registered in the electronic medical record DB 32a.

[0073] This embodiment also provides the same effects as the information processing system of the first embodiment. Furthermore, in this embodiment, the information processing device 10 acquires the latest physical data of each patient from the electronic medical record server 30 and recalculates body composition information using the latest physical data. This allows medical professionals to acquire appropriate body composition information without having to check whether the physical data of each patient is up to date. The modifications described in the first embodiment can also be applied to this embodiment.

[0074] (Embodiment 3) In this embodiment, an information processing system is described that does not include an information processing device 10. Instead, body composition information for each patient measured by a body composition analyzer 20 is directly transmitted to an electronic medical record server 30 and stored in an electronic medical record database 32a. When the electronic medical record server 30 receives the body composition information for each patient from the body composition analyzer 20, if the latest physical data for each patient is stored in the electronic medical record database 32a, the latest physical data is used to recalculate the body composition values ​​for each patient. The information processing system of this embodiment can be implemented using devices 20 and 30 similar to those of the information processing system of embodiment 1 shown in FIGS. 1 and 2 , and therefore a description of the configurations of the devices 20 and 30 is omitted. The body composition analyzer 20 and the electronic medical record server 30 may be configured to directly transmit and receive information via wired or wireless communication via a cable, or may be configured to transmit and receive information via a network N. A communication module such as NFC or a communication means such as Bluetooth may be used to connect the body composition analyzer 20 to the network N.

[0075] FIG. 10 is an explanatory diagram showing an example of the record layout of the electronic medical record DB 32a. The electronic medical record DB 32a shown in FIG. 10 includes a patient ID column, a name column, a patient information column, a physical data column, a body composition data column, etc. The patient information column stores personal information such as the patient's date of birth and contact information. The physical data column stores the patient's latest physical data (age, sex, height, and weight). The body composition data column stores the same information as the data ID column, measurement / recalculation column, date and time column, bioelectrical impedance column, physical data column, and body composition information column of the patient DB 12a shown in FIG. 3B. In addition to the above-mentioned configuration, the electronic medical record DB 32a may also store the patient's vital signs, medical history (medical history), examination information related to various examinations, treatment information related to treatment, surgery information related to surgery, medication history, etc.

[0076] FIG. 11 is a flowchart showing an example of a body composition information display processing procedure according to the third embodiment. 11, the left side shows the processing performed by the control unit 21 of the body composition monitor 20, and the right side shows the processing performed by the control unit 31 of the electronic medical record server 30. In the information processing system of this embodiment, the control unit 21 of the body composition monitor 20 performs the same processing as steps S11 to S12 in FIG. 4 (S41 to S42). In step S42, the control unit 21 transmits the patient ID, physical data, and measurement data stored in the patient DB 12a to the electronic medical record server 30.

[0077] When the control unit 31 of the electronic medical record server 30 receives data from the body composition analyzer 20, it issues a data ID and associates it with the received patient ID, and stores the issued data ID, the date and time and bioelectrical impedance included in the received measurement data, the received physical data, and the body composition information included in the received measurement data as body composition data in the electronic medical record DB 32a (S43). The control unit 31 stores "Measurement" in the measurement / recalculation column. The control unit 31 stores the received data of all patients in the electronic medical record DB 32a.

[0078] The control unit 31 acquires from the electronic medical record DB 32a the latest physical data of the patient whose body composition data is stored in the electronic medical record DB 32a (i.e., the physical data from the data in the electronic medical record DB 32a that is closest to the date and time when the bioelectrical impedance was measured) (S44). Here, the control unit 31 reads out the physical data (the most recently measured or registered physical data) stored in the physical data string corresponding to the patient ID of the patient whose body composition data is stored in the electronic medical record DB 32a. The control unit 31 then determines whether or not the physical data of the body composition monitor 20 needs to be updated based on the physical data stored in the electronic medical record DB 32a in step S43 (the physical data of the body composition monitor 20) and the physical data read out from the physical data string of the electronic medical record DB 32a (the physical data of the electronic medical record) (S45). For example, height and weight are stored in association with measurement dates and times in the physical data column of electronic medical record DB 32a, and control unit 31 reads the measurement dates and times when reading physical data from the physical data column of electronic medical record DB 32a. Then, control unit 31 compares the measurement dates and times of the physical data of body composition monitor 20 with the measurement dates and times of the physical data of the electronic medical record. If the measurement dates and times of the physical data of the electronic medical record are later, control unit 31 determines that the physical data of the electronic medical record is newer and that the physical data of body composition monitor 20 needs to be updated. On the other hand, if the measurement dates and times of the physical data of the electronic medical record are earlier, control unit 31 determines that the physical data of the electronic medical record is older and that the physical data of body composition monitor 20 does not need to be updated. If it is determined that the physical data of body composition monitor 20 does not need to be updated (S45: NO), control unit 31 ends the process.

[0079] If it is determined that the physical data of body composition monitor 20 needs to be updated (S45: YES), control unit 31 updates (changes) the physical data (first physical data) of body composition monitor 20 based on the physical data (second physical data) in the electronic medical record (S46). Then, control unit 31 calculates (recalculates) the body composition information (second body composition information) of the patient whose information was stored in electronic medical record DB 32a in step S43, using the updated physical data and the bioelectrical impedance stored in electronic medical record DB 32a in step S43 (S47). Step S47 is the same process as step S21 in FIG. 4.

[0080] Then, the control unit 31 stores the body composition information obtained by recalculation in the electronic medical record DB 32a in association with the same date and time as the measurement date and time stored in the electronic medical record DB 32a in step S43 (S48). Specifically, the control unit 31 issues a data ID and stores the issued data ID, the measurement date and time and bioelectrical impedance included in the body composition data stored in the electronic medical record DB 32a in step S43 in association with the patient ID of the patient in the electronic medical record DB 32a, the updated physical data (second physical data), and the recalculated body composition information (second body composition information). The control unit 31 also stores "recalculation" in the measurement / recalculation column. This allows the body composition information recalculated using the latest physical data stored in the physical data column of the electronic medical record DB 32a to be stored in association with the measurement date and time of the bioelectrical impedance used for the recalculation. Note that in step 43, multiple measurement dates and times are stored. When the measurement data is stored collectively, in the subsequent step S44, a plurality of second physical data corresponding to each measurement date and time is acquired from the electronic medical record server 30. Then, in step 45 and thereafter, for each measurement date and time (data ID), the first physical data stored in the patient DB 12a is compared with the second physical data acquired from the electronic medical record server 30 to determine whether the physical data needs to be updated.

[0081] Control unit 31 transmits an instruction to update the physical data obtained from electronic medical record DB 32a to the latest physical data to body composition monitor 20 (S49). For example, control unit 31 transmits the patient ID and the updated physical data to body composition monitor 20. When control unit 21 of body composition monitor 20 receives an instruction to update the physical data from electronic medical record server 30, it updates the physical data of the patient registered in patient DB 22a in association with the received patient ID to the physical data received from electronic medical record server 30 (S50). As a result, when the latest physical data is registered in electronic medical record DB 32a, the patient's physical data registered in body composition monitor 20 can also be automatically updated to the latest physical data.

[0082] If the control unit 31 stores information about multiple patients in the electronic medical record DB 32a in step S43, it executes steps S44 to S49 for all patients. As a result, when body composition information about multiple patients measured with the body composition analyzer 20 is sent to the electronic medical record server 30, it determines whether the latest physical data for each patient is registered in the electronic medical record DB 32a. If the latest physical data is available, the control unit 31 can recalculate the body composition information using the latest physical data, thereby obtaining appropriate body composition information for each patient. Furthermore, for the body composition information of a patient measured with the body composition analyzer 20, the control unit 31 can recalculate the body composition information using physical data measured at a date and time that is earlier than and closest to the date and time of measurement of the body composition information, thereby obtaining appropriate body composition information at the time of measurement of the body composition information.

[0083] This embodiment also provides the same effects as the information processing systems of the first and second embodiments. Furthermore, in this embodiment, the electronic medical record server 30 acquires the latest physical data of each patient from the electronic medical record DB 32a and recalculates body composition information using the latest physical data. This allows medical personnel to acquire appropriate body composition information without having to check whether the physical data of each patient is up to date. The modifications described in the first and second embodiments can also be applied to this embodiment.

[0084] The information processing device 10 in the above-described first and second embodiments is configured to store in the patient DB 12a both the body composition information measured by the body composition analyzer 20 and the body composition information recalculated by the information processing device 10, and the electronic medical record server 30 in the third embodiment is configured to store in the electronic medical record DB 32a both the body composition information measured by the body composition analyzer 20 and the body composition information recalculated by the electronic medical record server 30, but is not limited to this configuration. In each of the above-described embodiments, if there is newer physical data than the physical data used to calculate the body composition information measured by the body composition analyzer 20, the body composition information is recalculated by the information processing device 10 or the electronic medical record server 30. Therefore, it is considered that the body composition information recalculated by the information processing device 10 or the electronic medical record server 30 is closer to the patient's current condition than the body composition information measured by the body composition analyzer 20. Therefore, when the information processing device 10 or the electronic medical record server 30 recalculates the body composition information measured by the body composition analyzer 20 and stored in the patient DB 12a or the electronic medical record DB 32a, the information processing device 10 or the electronic medical record server 30 may be configured to erase the body composition information measured by the body composition analyzer 20 and stored in the patient DB 12a or the electronic medical record DB 32a, and store (overwrite and save) only the recalculated body composition information in the patient DB 12a or the electronic medical record DB 32a. Furthermore, when the information processing device 10 or the electronic medical record server 30 recalculates the body composition information, the information processing device 10 or the electronic medical record server 30 may erase the physical data stored in the patient DB 12a and the electronic medical record DB 32a, and store (overwrite and save) the physical data used in the recalculation of the body composition information in the patient DB 12a or the electronic medical record DB 32a.

[0085] The embodiments disclosed herein are illustrative in all respects and are not to be considered as limiting. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.

[0086] The matters described in each of the above-mentioned embodiments can be combined with each other.
