[0007] Hereinafter, embodiments of a medical information processing apparatus, a medical information processing system, and a medical information processing program will be described with reference to the drawings. In the following embodiments, parts denoted by the same reference numerals perform the same operations, and redundant descriptions will be omitted as appropriate.

[0008] (Embodiment) FIG. 1 is a block diagram showing an example of the configuration of a medical information processing system 1 including a medical information processing apparatus 30 according to an embodiment. As shown in FIG. 1, the medical information processing system 1 according to the embodiment includes a measuring device 10 and a medical information processing apparatus 30. As shown in FIG. 1, the measuring device 10, a hospital information system (HIS) 20, and the medical information processing apparatus 30 are interconnected via a network. Note that various servers such as a radiology information system (RIS) and a picture archiving and communication systems (PACS), and various modalities may be connected to the network.

[0009] The measuring device 10 measures the vital signs of a subject. The vital signs are, for example, blood pressure, blood glucose level, pulse, respiration, body temperature, oxygen saturation, and the like. In FIG. 1, one measuring device 10 is shown, but a plurality of measuring devices may be connected to a network according to the type of vital sign. Since known devices can be applied as the measuring device 10 according to the type of vital sign, the description thereof is omitted. Also, since known devices can be applied as the RIS server, PACS server, and various modalities that can be connected to the network, the description thereof is omitted.

[0010] The hospital information system 20 is a system for managing information within a hospital. The hospital information system 20 manages all the information managed by the hospital and includes an accounting system, a treatment execution information input system, an electronic medical registration system, and the like. Since known systems can be applied as the hospital information system 20, the description thereof is omitted.

[0011] The medical information processing device 30 acquires the vital signs of a subject from the measuring device 10 via a network and executes various processes based on the acquired vital signs. The medical information processing device 30 may also be referred to as a medical information analysis device or the like. For example, the medical information processing device 30 is realized by a computer device such as a workstation. Further, the medical information processing device 30 causes the result of the process processed based on the vital signs to be displayed on the display 32. Also, the medical information processing device 30 notifies the user of the result of the process processed based on the vital signs and the like by voice via a speaker 35 (not shown).

[0012] As shown in FIG. 1, the medical information processing device 30 includes an input interface 31, a display 32, a memory 33, a processing circuit 34, and a speaker 35.

[0013] The input interface 31 is realized by a trackball, a switch, buttons, a mouse, a keyboard, a touch pad for performing input operations by touching an operation surface, a touch screen in which a display screen and a touch pad are integrated, a non-contact input circuit using an optical sensor, a voice input circuit (such as a microphone), etc. for performing various instructions and various settings. The input interface 31 converts the input operation received from the operator into an electrical signal and outputs it to the processing circuit 34. Note that the input interface 31 is not limited to those equipped with physical operation components such as a mouse and a keyboard. For example, a processing circuit for receiving an electrical signal corresponding to an input operation from an external input device provided separately from the medical information processing device 30 and outputting this electrical signal to the processing circuit 34 is also included in the example of the input interface 31. The input interface 31 is an example of an input unit.

[0014] The display 32 displays various information under the control of the display control function 34f. For example, the display 32 displays a GUI (Graphical User Interface) for receiving an operator's instruction and various vital signs. For example, the display 32 is a liquid crystal display or a CRT (Cathode Ray Tube) display. The display 32 is an example of a display unit.

[0015] The memory 33 is realized by, for example, semiconductor memory elements such as RAM (Random Access Memory) and flash memory, a hard disk, an optical disk, etc. For example, the memory 33 stores the vital signs acquired from the measuring device 10. Also, for example, the memory 33 stores programs for each circuit included in the medical information processing device 30 to realize its functions. The memory 33 is an example of a storage unit.

[0016] The processing circuit 34 controls the operation of the entire medical information processing device 30 by executing an acquisition function 34a, a trend calculation function 34b, a determination function 34c, a decision function 34d, a prediction calculation function 34e, and a display control function 34f.

[0017] The processing circuit 34 acquires vital signs from the measuring device 10 by reading and executing a program corresponding to the acquisition function 34a from the memory 33. The acquisition function 34a stores the vital signs in the memory 33. Note that the vital signs acquired by the acquisition function 34a are not limited to one, and for example, a plurality of vital signs including other vital signs may be acquired from a plurality of measuring devices respectively. The processing circuit 34 that realizes the acquisition function 34a is an example of an acquisition unit.

[0018] The processing circuit 34 reads and executes a program corresponding to the trend calculation function 34b from the memory 33. Thereby, the trend calculation function 34b calculates the trend of the acquired vital signs based on the values at a plurality of times in the acquired vital signs. For example, the trend calculation function 34b calculates the slope (first derivative value) of the vital signs at the current time using the value of the vital signs at the current time and the value of the vital signs a predetermined time before the current time. Thereby, the trend calculation function 34b calculates the first derivative value of the vital signs at the current time as the trend of the vital signs.

[0019] Note that the trend of the vital signs at the current time is not limited to the above first derivative value (slope of the vital signs). For example, the trend calculation function 34b may calculate a higher-order derivative value such as the second derivative value of the vital signs at the current time using the values at a plurality of times in the vital signs. The calculation for obtaining the trend of the vital signs is not limited to the above, and known calculation methods can be appropriately used. The trend calculation function 34b stores the calculated trend of the vital signs in the memory 33. The processing circuit 34 that realizes the trend calculation function 34b is an example of a trend calculation unit.

[0020] The processing circuit 34 reads and executes a program corresponding to the determination function 34c from the memory 33. Thereby, the determination function 34c determines whether or not the vital sign is included in the first range. For example, the determination function 34c reads the first range from the memory 33. The first range is a range preset according to the type of vital sign and corresponds to the stable state of the subject's vital signs. Next, the determination function 34c determines whether or not the acquired vital sign has been included in the first range over a predetermined past period from the current time.

[0021] In addition, the processing circuit 34 determines, by the determination function 34c, whether or not the calculated trend is included in the second range. Specifically, the determination function 34c reads the second range from the memory 33. The second range is a range preset according to the type of vital sign and corresponds to the stable state of the vital sign regarding the trend of the subject's vital signs. Next, the determination function 34c determines whether or not the trend of the acquired vital sign has been included in the second range over a predetermined past period from the current time. For example, the determination function 34c determines whether or not the trend of the vital sign (for example, a plurality of first derivative values in the vital sign) has been included in the second range over a predetermined past period from the current time. The determination function 34c stores the determination result in the memory 33. The processing circuit 34 that realizes the determination function 34c is an example of a determination unit.

[0022] The processing circuit 34 reads and executes a program corresponding to the determination function 34d from the memory 33. Further, the determination function 34d reads the determination result by the determination function 34c from the memory 33. Thereby, when it is determined that the vital sign is not included in the first range and / or the calculated tendency is not included in the second range (hereinafter referred to as vital sign failure determination), the determination function 34d determines a plurality of treatments for the subject based on the vital sign. The plurality of treatments correspond to, for example, the administration of a plurality of drugs that have a similar effect on the vital sign. Note that the plurality of treatments are not limited to the administration of drugs, and may be various treatments for stabilizing the vital sign, such as intubation for the subject, wearing an oxygen mask on the subject, and adjusting the amount of oxygen delivered.

[0023] Hereinafter, for the sake of specific explanation, it is assumed that the plurality of treatments are the administration of a plurality of drugs. At this time, the memory 33 stores, for example, a correspondence table of the names of a plurality of treatments for the types of vital signs (hereinafter referred to as the vital treatment correspondence table). The processing circuit 34 determines a plurality of treatments by reading the vital treatment correspondence table from the memory 33 in response to the vital sign failure determination by the determination function 34d and collating the vital sign related to the determination with the vital treatment correspondence table. For example, when the vital sign related to the vital sign failure determination is blood pressure and the vital sign failure determination is a decrease in blood pressure and / or a tendency to decrease blood pressure, the plurality of treatments correspond to the administration of a plurality of drugs that increase blood pressure. The processing circuit 34 that realizes the determination function 34d is an example of a determination unit.

[0024] The processing circuit 34 reads and executes a program corresponding to the prediction calculation function 34e from the memory 33. As a result, based on a plurality of treatments, vital signs, and the trends of the vital signs, the prediction calculation function 34e calculates a plurality of prediction lines of the vital signs when a plurality of treatments are respectively applied to the subject. For example, the prediction calculation function 34e reads a preset calculation formula from the memory 33 according to the determined plurality of treatments. The calculation formula takes, for each treatment, the value of the current vital sign and the trend of the vital sign (such as the differential value of the vital sign) as inputs, and calculates the prediction line of the vital sign from the value of the current vital sign over a predetermined period. The calculation formula is preset for each of a plurality of treatments, for example, a plurality of drugs. Instead of the calculation formula, a correspondence table of the prediction line with respect to the value of the current vital sign and the trend of the vital sign may be used. The predetermined period is a preset time interval, for example, corresponding to the duration of the change in the vital sign due to the treatment. Since known calculation formulas and correspondence tables can be applied, the description thereof is omitted.

[0025] The prediction calculation function 34e inputs the value of the current vital sign and the trend of the vital sign into the calculation formula or the correspondence table read for each of the determined plurality of treatments (a plurality of drugs). As a result, the prediction calculation function 34e calculates the prediction line over a predetermined period for each of the determined plurality of treatments. Note that patient information of the subject may be further input into the calculation formula or the correspondence table. The patient information is, for example, information about the subject such as the age, height, weight, and build of the subject, and is obtained by the acquisition function 34a from, for example, the hospital information system 20 or the like. At this time, the prediction calculation function 34e can input the value of the current vital sign, the trend of the vital sign, and the patient information into the calculation formula or the correspondence table, and output a more accurate prediction line compared to when the patient information is not used. The prediction calculation function 34e stores the prediction line of the vital sign over a predetermined period from the value of the current vital sign in the memory 33. The processing circuit 34 that realizes the prediction calculation function 34e is an example of a prediction calculation unit.

[0026] The processing circuit 34 reads and executes a program corresponding to the display control function 34f from the memory 33. For example, the display control function 34f causes the vital signs of the subject to be displayed on the display 32 in time series. FIG. 2 is a diagram showing an example of the temporal change in blood pressure as a vital sign of the subject. In the graph shown in FIG. 2, the horizontal axis represents time and the vertical axis represents blood pressure. In the graph shown in FIG. 2, the vertical line TCT indicates the current time. As shown in FIG. 2, the vital sign VS indicating blood pressure changes over time.

[0027] In the graph shown in FIG. 2, the dotted ellipse indicates a predetermined past period PP. In the predetermined past period PP shown in FIG. 2, a decrease in blood pressure is shown in the vital sign VS. The vital sign EVS in the future from the current time TCT indicates a vital sign predicted from the past vital sign (hereinafter referred to as the predicted vital sign) EVS. The predicted vital sign EVS is calculated by a known method based on the past vital sign VS, for example, by the trend calculation function 34b.

[0028] The display control function 34f causes a plurality of prediction lines corresponding to a plurality of treatments calculated by the prediction calculation function 34e to be displayed on the display 32 together with the vital sign VS over a predetermined period from the current time. Note that the display control function 34f may cause the plurality of prediction lines to be displayed on the display 32 together with the vital sign VS and the names of the plurality of treatments (hereinafter referred to as the plurality of treatments). Thereby, the display 32 displays the calculated plurality of prediction lines together with the vital sign VS (including the plurality of treatments). The processing circuit 34 that realizes the display control function 34f is an example of a display control unit.

[0029] FIG. 3 is a diagram showing an example of a plurality of prediction lines MA, MB, MC and a vital sign VS displayed based on the determination result of the vital sign VS in FIG. 2. In FIG. 3, three drugs (drug A, drug B, drug C) are proposed to the user as a plurality of treatments. Further, in FIG. 3, as an example, three prediction lines MA, MB, MC corresponding to the three drugs (drug A, drug B, drug C) are shown in different line types and together with the predicted vital sign EVS. The three drugs, drug A, drug B, and drug C shown in FIG. 3 are drugs that have the same effect on blood pressure. Note that the three prediction lines MA, MB, MC may be displayed on the display 32 together with the names of the three drugs corresponding to the three prediction lines MA, MB, MC (or the three treatments corresponding to the three drugs (administration of the three drugs)).

[0030] The arrow and the schematic diagram SY of the syringe shown in FIG. 3 indicate the time points when the three drugs are each hypothetically administered. As shown in FIG. 3, the prediction line MA for drug A indicates that the blood pressure rises faster than the prediction line MB for drug B and the prediction line MC for drug C. Also, the prediction line MB for drug B indicates that the blood pressure rises more slowly than the prediction line MA and faster than the prediction line MC. Further, the prediction line MC for drug C indicates that the blood pressure rises more slowly than the prediction lines MA and MB.

[0031] The speaker 35 is an acoustic device that converts an electrical signal into sound and outputs the converted sound. The speaker 35 may be referred to as a voice output unit. The speaker 35 outputs various sounds according to the output from the processing circuit 34. Details of the output sound will be described later.

[0032] As described above, the overall configuration of the medical information processing system 1 according to the embodiment has been described. Hereinafter, processing related to guidance for stabilizing vital signs (hereinafter referred to as vital stability guidance processing) will be described. As an example, the case where there are five vital signs for the subject will be described. FIGS. 4 and 5 are diagrams showing an example of a situation in which the vital stability guidance processing is performed.

[0033] As shown in FIG. 4, when the first vital sign, the third vital sign, and the fourth vital sign are not stable, the next treatment for the subject cannot be performed. That is, when all of the first to fifth vital signs are stable, as shown in FIG. 5, the next treatment (examination, surgery, etc.) for the subject can be performed. The vital stability guide process is performed, for example, to guide the user to perform a treatment such that all the vital signs of the subject become stable.

[0034] FIGS. 6 and 7 are flowcharts showing an example of the procedure of the vital stability guide process. Prior to the execution of the vital stability guide process, the measuring device 10 is appropriately arranged so as to acquire the vital signs of the subject. For example, the vital detection part (various sensors, etc.) in the measuring device 10 is brought into contact with the subject.

[0035] (Vital Stability Guide Process) (Step S601) The measuring device 10 measures the vital signs of the subject. The processing circuit 34 acquires the vital signs by the acquisition function 34a. When a plurality of measuring devices 10 are installed, the acquisition function 34a acquires a plurality of vital signs from the plurality of measuring devices 10, respectively. The acquisition function 34a causes the vital signs to be displayed on the display 32. The display 32 displays the vital sign VS, for example, as shown in FIG. 2. When a plurality of vital signs are acquired, the display 32 displays, for example, the vital sign designated by the user and / or the vital sign not included in the first range. Further, the acquisition function 34a causes the vital signs to be stored in the memory 33.

[0036] (Step S602) The processing circuit 34 calculates the trend of the vital signs by means of the trend calculation function 34b. For example, the trend calculation function 34b calculates the trend of the vital signs using the values at a plurality of times in the vital signs included in a predetermined past period PP in the vital signs displayed on the display 32. The trend calculation function 34b stores the calculated trend of the vital signs in the memory 33.

[0037] (Step S603) The processing circuit 34 determines whether the vital signs are stable by means of the determination function 34c. Specifically, the determination function 34c reads out the first range and the second range from the memory 33. Next, the determination function 34c determines whether the vital signs are included in the first range over a predetermined past period PP from the current time. In addition, the determination function 34c determines whether the trend of the vital signs is included in the second range over a predetermined past period PP from the current time.

[0038] When it is determined by the determination function 34c that there is a vital sign defect, that is, when the vital signs are not in a stable state (No in step S603), the process of step S604 is executed. When it is determined that the vital signs are included in the first range and the trend of the vital signs is included in the second range, that is, when it is determined that the vital signs are in a stable state (Yes in step S603), the process of step S619 is executed.

[0039] (Step S604) The processing circuit 34 determines a plurality of treatments based on the vital signs by means of the determination function 34d. For example, the determination function 34d determines a plurality of treatments, such as drug A, drug B, and drug C, by collating the type of vital signs with the vital treatment correspondence table.

[0040] (Step S605) The processing circuit 34 calculates a plurality of prediction lines of the vital signs when a plurality of treatments are applied to the subject based on the plurality of treatments, the vital signs, and the trend of the vital signs by the prediction calculation function 34e. When the plurality of treatments are drug A, drug B, and drug C, the prediction calculation function 34e calculates a prediction line MA corresponding to drug A based on drug A, the vital signs, and the trend of the vital signs. Further, the prediction calculation function 34e calculates a prediction line MB corresponding to drug B based on drug B, the vital signs, and the trend of the vital signs. Subsequently, the prediction calculation function 34e calculates a prediction line MC corresponding to drug C based on drug C, the vital signs, and the trend of the vital signs.

[0041] (Step S606) The processing circuit 34 causes the display 32 to display the plurality of prediction lines together with the vital signs by the display control function 34f. Thereby, the display 32 displays the plurality of prediction lines MA, MB, and MC together with the vital sign VS and the plurality of treatments as shown in FIG. 3, for example.

[0042] (Step S607) The input interface 31 inputs a target value regarding the vital signs and a target arrival time until the vital signs reach the target value by the user's voice. That is, the input interface 31 inputs the target value and the target arrival time by voice input. Note that the input of the target value and the target arrival time is not limited to the user's voice input, and may be input by an input operation on a keyboard touch panel or the like. The input interface 31 stores the input target value and target arrival time in the memory 33.

[0043] (Step S608) When it is input via the input interface 31 that any one of a plurality of treatments has been performed on the subject, the processing circuit 34 causes the display control function 34f to display, on the display 32, the prediction line of the treatment performed on the subject and the vital signs. For example, when drug B is administered to the subject, the display 32 displays the prediction line MB shown in FIG. 3, the vital signs VS, the future vital signs EVS from the current time TCT, and the current time TCT. At this time, the prediction line MB from the administration time of drug B to the subject to the target value is displayed thinly. Note that the processing in this step may be performed before step S607.

[0044] (Step S609) Prior to this step, the acquisition function 34a acquires the value of the current vital signs. The processing circuit 34 calculates, by the prediction calculation function 34e, the difference between the value of the current vital signs and the target value, and the trend of the vital signs from the start time of the treatment performed on the subject (hereinafter referred to as the post-treatment vital trend). Further, the prediction calculation function 34e calculates the elapsed time from the start time of the treatment performed on the subject among the plurality of treatments. The prediction calculation function 34e stores the calculated difference, elapsed time, and post-treatment vital trend in the memory 33.

[0045] (Step S610) The processing circuit 34 causes the prediction calculation function 34e to output, from the speaker 35 in voice, the calculated post-treatment vital trend and difference. By the voice output from the speaker 35, the elapsed time, the difference (also referred to as a gap), and the post-treatment vital trend are notified to the user. That is, the speaker 35 outputs the difference (also referred to as a gap) and the post-treatment vital trend in voice. Note that the speaker 35 may further output the elapsed time from the start time of the treatment in voice. Note that the maximum time for which the notification of the elapsed time is performed may be preset according to the treatment performed on the subject. For example, the maximum time for which the notification of the elapsed time is performed is preset for each type of drug, regardless of the time to reach the target.

[0046] FIG. 8 is a diagram showing an example of voice output of elapsed time, gap, and post-treatment vital trend based on voice input of a target value and a target achievement time regarding drug administration. The speech balloon VI based on the schematic diagram of the microphone shown in FIG. 8 shows voice input of the target value and the target achievement time regarding the administration of drug B to the subject. Further, the speech balloon VO based on the schematic diagram of the speaker 35 shown in FIG. 8 shows voice output of the elapsed time, the difference (also referred to as a gap), and the post-treatment vital trend at the current time TCT. Also, as shown in FIG. 8, the target achievement time TTR and / or the target value TV may be further displayed on the display 32. The user is notified of the elapsed time, the difference (also referred to as a gap), and the post-treatment vital trend by the voice output VO. Note that the voice notification is not limited to the above, and may be the difference and the post-treatment vital trend.

[0047] (Step S611) The processing circuit 34 determines, by the determination function 34c, whether or not the target achievement time has elapsed since the start time of the treatment. When the elapsed time exceeds the target achievement time (Yes in step S611), the process of step 614 is executed. When the elapsed time does not exceed the target achievement time (No in step S611), the process of step S612 is executed.

[0048] (Step S612) The processing circuit 34 determines, by the determination function 34c, whether or not the vital sign has reached the target value. That is, the determination function 34c determines whether or not the vital sign has reached the target value by the target achievement time. When the vital sign has reached the target value (Yes in step S612), the process of step 613 is executed. When the vital sign has not reached the target value (No in step S612), the processes after step S608 are executed.

[0049] (Step S613) The speaker 35 outputs an instruction to maintain the vital sign (hereinafter referred to as the maintenance instruction) in voice. That is, when the vital sign reaches the target value earlier than the target arrival time, the speaker 35 outputs the maintenance instruction in voice. Note that the voice output from the speaker 35 is not limited to the maintenance instruction, and may be, for example, an instruction to administer a drug to increase or decrease the vital sign, or a treatment method when treatment is necessary for the subject.

[0050] FIG. 9 is a diagram showing an example when the vital sign reaches the target value earlier than the target arrival time. As shown in FIG. 9, the vital sign VS reaches the target value TV at the current time TCTTR earlier than the target arrival time TTR. At this time, the speaker 35 outputs, as the maintenance instruction VMI, for example, as shown in FIG. 9, "Please administer drug A to maintain the waveform" in voice. Depending on the trend of the vital sign, the speaker 35 may also output in voice, such as "It is dangerous to keep rising, so please perform ○○ treatment." The ○○ treatment is, for example, a treatment name preset according to a correspondence table of the vital sign type, the administered drug, and the elapsed time.

[0051] (Step S614) The processing circuit 34 estimates at least one medical condition related to the subject based on a plurality of vital signs including the vital sign displayed on the display 32 and the treatment performed on the subject by the determination function 34d. Specifically, the determination function 34d reads out a correspondence table of medical conditions for the vital sign and a plurality of treatments (hereinafter referred to as the vital sign-medical condition correspondence table) from the memory 33. The vital sign-medical condition correspondence table is preset and stored in the memory 33. The determination function 34d estimates at least one medical condition related to the subject by comparing the plurality of vital signs and the treatment performed on the subject with the vital sign-medical condition correspondence table.

[0052] That is, after the elapse of the target arrival time, when the vital signs do not reach the target values, the determination function 34d estimates at least one medical condition based on a plurality of vital signs and the treatments performed. For example, if the unstable vital sign is blood pressure, the estimated medical conditions are ischemic heart disease, bleeding, etc. The determination function 34d stores the estimated medical condition in the memory 33. Note that the determination function 34d may determine the most important vital sign as the basis for estimation among the plurality of vital signs in the estimation of the medical condition. For example, when the estimated medical condition is ischemic heart disease and / or bleeding, the determination function 34d determines the vital sign of blood pressure as the most important vital sign. The determination function 34d stores the estimated medical condition and the most important vital sign in the memory 33.

[0053] (Step S615) The processing circuit 34 determines, by the determination function 34d, at least one treatment pattern for improving the at least one medical condition based on the at least one estimated medical condition. For example, the determination function 34d reads out a correspondence table of treatment patterns for medical conditions (hereinafter referred to as the medical condition-treatment correspondence table) from the memory 33. The medical condition-treatment correspondence table is preset and stored in the memory 33. The determination function 34d determines at least one treatment pattern for the subject by collating the estimated medical condition with the medical condition-treatment correspondence table. For example, when the estimated medical condition is bleeding, the determined treatment pattern corresponds to various hemostatic treatments. The determination function 34d stores the determined treatment pattern in the memory 33.

[0054] (Step S616) The processing circuit 34 determines the priorities of a plurality of treatment patterns based on the vital signs by the determination function 34d. For example, the determination function 34d reads out a correspondence table (hereinafter referred to as the treatment priority correspondence table) indicating the treatment priorities for the plurality of treatment patterns from the memory 33. The treatment priority correspondence table is preset and stored in the memory 33. The determination function 34d determines the priorities of the plurality of treatment patterns by collating each of the determined plurality of treatment patterns with the disease state treatment correspondence table. The determination function 34d stores the priorities of the plurality of treatment patterns in the memory 33.

[0055] (Step S617) The processing circuit 34 causes the display control function 34f to display the plurality of treatment patterns on the display 32 together with the estimated disease state in order of priority. When the process of step S616 is omitted, the display 32 displays at least one specified disease state and at least one determined treatment pattern. At this time, the display 32 may display the most important vital sign.

[0056] (Step S618) The processing circuit 34 determines whether the vital signs have reached the target value by the determination function 34c. When the vital signs have reached the target value (Yes in step S618), the process of step S613 is executed. When the vital signs have not reached the target value (No in step S618), the processes after step S614 are executed.

[0057] FIG. 10 is a diagram showing an example of a display when a vital sign reaches a target value at a time later than the target arrival time. As shown in FIG. 10, the vital sign VS reaches the target value TV at the current time TCT that is later than the target arrival time TTR. At this time, for example, as shown in FIG. 10, the speaker 35 outputs audibly, "Although the target could not be achieved by the target arrival time, no treatment is necessary because of the upward trend." Depending on the trend of the vital sign, the speaker 35 may output audibly, "Since the target could not be achieved, please administer drug B again at ○○ ml," etc. ○○ ml is the dosage of drug B preset by a correspondence table according to the trend of the vital sign, the administered drug, and the elapsed time.

[0058] (Step S619) The processing circuit 34 determines, by the determination function 34c, whether all vital signs are stable. For example, the determination function 34c determines whether each of a plurality of vital signs including the vital sign is included in each of a plurality of first ranges corresponding to the plurality of vital signs, and whether the trend of each of the plurality of vital signs is included in each of a plurality of second ranges corresponding to the plurality of vital signs. Specifically, when all of the plurality of vital signs are included in their respective first ranges and all of the trends of the plurality of vital signs are included in their respective second ranges, the determination function 34c determines that all vital signs are stable. If not all vital signs are stable (No in step S619), the processing after step S601 is repeated for the other vital signs. Also, if all vital signs are stable (Yes in step S619), the processing of step S620 is executed.

[0059] (Step S620) The processing circuit 34 causes the display control function 34f to display the next treatment on the display 32 as shown in FIG. 5. Thereby, the display 32 displays at least one next treatment for the subject. The next treatment is a treatment according to the subject's medical condition, and is, for example, an examination, a surgery, or the like.

[0060] The medical information processing device 30 according to the above-described embodiment acquires the vital signs of a subject, calculates the trend of the vital signs based on the values at a plurality of times in the vital signs, determines whether the vital signs are included in a first range and whether the trend is included in a second range, and when it is determined that the vital signs are not included in the first range and / or when it is determined that the trend is not included in the second range, determines a plurality of treatments for the subject based on the vital signs, calculates a plurality of prediction lines of the vital signs when the plurality of treatments are respectively applied to the subject based on the plurality of treatments, the vital signs, and the trend, and displays the plurality of prediction lines together with the vital signs. Further, in the medical information processing device 30 according to the embodiment, the plurality of treatments correspond to the administration of a plurality of drugs that have the same effect on the vital signs.

[0061] Accordingly, according to the medical information processing device 30 according to the embodiment, it is possible to propose a plurality of next treatments based on the vital signs of the subject by making a determination using the vital signs and the trend of the vital signs (the values of the vital signs at a plurality of times). In addition, according to the medical information processing device 30 according to the embodiment, it is possible to display, together with the vital signs, a prediction line indicating how the vital signs will change when the determined plurality of treatments are hypothetically implemented. From these facts, according to the medical information processing device 30 according to the embodiment, it is possible to visually provide the user with a prediction of a treatment for stabilizing the vital signs, for example, a prediction of the administration of a plurality of drugs that have the same effect on the vital signs, and it is possible to improve the efficiency regarding the implementation of the treatment for stabilizing the vital signs. From the above, according to the medical information processing device 30 according to the embodiment, it is possible to improve the throughput of the treatment for stabilizing the vital signs.

[0062] In addition, the medical information processing apparatus 30 according to the embodiment further calculates a plurality of prediction lines using the patient information of the subject. Thereby, according to the medical information processing apparatus 30 according to the embodiment, the accuracy of the prediction lines can be improved. Thereby, according to the medical information processing apparatus 30 according to the embodiment, the throughput of the treatment for stabilizing the vital signs can be further improved.

[0063] In addition, the medical information processing apparatus 30 according to the embodiment inputs a target value related to the vital signs and a target arrival time until the vital signs reach the target value, calculates the difference between the value of the vital signs and the target value, and outputs, in voice, the tendency of the vital signs from the start time of the treatment performed on the subject among the plurality of treatments and the difference. Thereby, according to the medical information processing apparatus 30 according to the embodiment, the user can easily grasp whether the value of the vital signs is likely to reach the target value by the target arrival time.

[0064] In addition, the medical information processing apparatus 30 according to the embodiment determines whether the vital signs have reached the target value by the target arrival time, and when the vital signs reach the target value earlier than the target arrival time, outputs an instruction to maintain the vital signs in voice. Thereby, according to the medical information processing apparatus 30 according to the embodiment, when the value of the vital signs reaches the target value by the target arrival time, the user can be appropriately notified of the process related to the maintenance of the vital signs. Therefore, according to the medical information processing apparatus 30 according to the embodiment, the user can appropriately execute the treatment for stabilizing and maintaining the vital signs.

[0065] In addition, the medical information processing apparatus 30 according to the embodiment further outputs, in voice, the elapsed time from the start time of the treatment performed on the subject among the plurality of treatments. Thereby, according to the medical information processing apparatus 30 according to the embodiment, the user can easily grasp the elapsed time since the start of the treatment.

[0066] Further, when the vital signs do not reach the target value after the elapse of the target arrival time, the medical information processing device 30 according to the embodiment estimates at least one medical condition related to the subject based on a plurality of vital signs including the vital signs and the treatment performed on the subject, determines at least one treatment pattern for improving at least one medical condition based on the estimated at least one medical condition, and displays at least one medical condition and at least one treatment pattern. Thereby, according to the medical information processing device 30 according to the embodiment, when the vital signs do not reach the target value after the elapse of the target arrival time, the user can easily grasp an example of the medical condition and the treatment pattern related to the vital signs that are not in a stable state (unstable state). Thereby, according to the medical information processing device 30 according to the embodiment, the user can efficiently consider various treatments related to the unstable vital signs. For this reason, according to the medical information processing device 30 according to the embodiment, even if the vital signs are in an unstable state after exceeding the target arrival time, the possibility of appropriate response can be improved, and the throughput of the treatment for stabilizing the vital signs can be improved.

[0067] Also, in estimating the medical condition, the medical information processing device 30 according to the embodiment determines the vital sign with the highest importance as the basis for estimating the medical condition among the plurality of vital signs, and displays the vital sign with the highest importance. Thereby, according to the medical information processing device 30 according to the embodiment, the user can easily grasp the vital sign with the highest importance among the vital signs serving as the basis for estimating the medical condition regarding the unstable vital signs. For this reason, according to the medical information processing device 30 according to the embodiment, it is possible to quickly respond to the vital sign with the highest importance, and the throughput of the treatment for stabilizing the vital signs can be improved.

[0068] In addition, the medical information processing apparatus 30 according to the embodiment determines the priority order of the treatment patterns based on the vital signs and displays the treatment patterns in accordance with the priority order. Thus, according to the medical information processing apparatus 30 according to the embodiment, regarding the vital signs in an unstable state, the user can easily grasp the treatment patterns in accordance with the priority order. Therefore, according to the medical information processing apparatus 30 according to the embodiment, by implementing the treatment patterns for the vital signs in an unstable state, it is possible to quickly respond to the vital signs in an unstable state and improve the throughput of the measures for stabilizing the vital signs.

[0069] In addition, when it is determined that each of a plurality of vital signs including the vital signs is included in each of a plurality of first ranges respectively corresponding to the plurality of vital signs and the tendency of each of the plurality of vital signs is included in a plurality of second ranges respectively corresponding to the plurality of vital signs, the medical information processing apparatus 30 according to the embodiment displays at least one next treatment for the subject. Therefore, according to the medical information processing apparatus 30 according to the embodiment, as shown in FIG. 5, when all the vital signs are stable, the user can quickly consider the application of the next treatment for the subject. Thereby, according to the medical information processing apparatus 30 according to the embodiment, it is possible to improve the throughput of the treatment for the subject after all the vital signs are stable.

[0070] From these, according to the medical information processing apparatus 30 according to the embodiment, it is possible to notify various treatments for the subject and the like based on the determination based on the vital signs of the subject and the tendency of the vital signs, and improve the throughput of the measures for stabilizing the vital signs in an unstable state and the throughput regarding the implementation of the treatment after all the vital signs are stable. Thereby, according to the medical information processing apparatus 30 according to the embodiment, it is possible to improve the throughput of the response to the subject including the measures for stabilizing the vital signs even in an emergency.
