Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, as a method for discriminating the condition of a subject, for example, a discrimination method such as NEWS (National Early Warning Score) is known. When discriminating the condition of a subject using such a discrimination method, the condition information based on the discrimination method and the biological information used for the discrimination method used may be displayed on a biological information monitor or the like. However, when it is desired to evaluate the condition of the subject more comprehensively and / or in more detail, it may be desirable to confirm not only the biological information used for the discrimination method used but also other biological information not used for the discrimination method. Thus, when discriminating the condition of a subject using a discrimination method such as NEWS, there is a need to confirm not only the biological information necessary for the execution of the discrimination method but also the biological information that is not necessary.

[0005] The purpose of this disclosure is to provide a display data generation device, a display data generation method, a computer program, and a non-temporary computer-readable medium that can display not only biological information used in a discrimination method for determining the condition of a subject, but also biological information not used in said discrimination method. [Means for solving the problem]

[0006] A display data generation apparatus according to one embodiment for achieving the above objective is: An input interface into which the subject's biometric information is entered, Processor and A display data generation device comprising: a memory storing at least one instruction executable by the processor, When at least one of the instructions is executed by the processor, the display data generation device generates display data in which the biological information used in a discrimination method for determining the condition of the subject, from the biological information input to the input interface, is displayed in a first area, and the biological information not used in the discrimination method is displayed in a second area different from the first area.

[0007] Furthermore, a method for generating display data in one embodiment for achieving the above objective is: This is a display data generation method performed by a display data generation device, which includes the step of generating display data in which the biological information of a subject used in a discrimination method for determining the condition of the subject is displayed in a first area, and the biological information not used in the discrimination method is displayed in a second area different from the first area.

[0008] Furthermore, a computer program relating to one aspect for achieving the above objective is: A computer program that can be executed by a processor provided in a display data generation device, When the aforementioned computer program is executed, the display data generation device will, Display data is generated in which, among the subject's biological information, the biological information used in a discrimination method for determining the subject's condition is displayed in a first area, and the biological information not used in the discrimination method is displayed in a second area different from the first area.

[0009] Furthermore, a non-temporary computer-readable medium relating to one aspect for achieving the above objective includes: The above computer program is stored.

[0010] According to the display data generation device with the above configuration, the biological information used in the discrimination method for determining the subject's condition is displayed in the first area, and the biological information not used in the discrimination method is displayed in the second area. In other words, the area in which the biological information used in the discrimination method is displayed is different from the area in which the biological information not used in the discrimination method is displayed. Therefore, the display data generation device with the above configuration can display both the biological information used in the discrimination method for determining the subject's condition and the biological information not used in the discrimination method. Furthermore, the same effect can be achieved with the display data generation method, computer program, and non-temporary computer-readable medium with the above configuration. [Effects of the Invention]

[0011] According to this disclosure, it is possible to provide a display data generation device, a display data generation method, a computer program, and a non-temporary computer-readable medium that can display not only biological information used in a discrimination method for determining the condition of a subject, but also biological information not used in said discrimination method.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the drawings. In the description of this embodiment, for convenience of explanation, the "left - right direction" and "up - down direction" may be referred to as appropriate. These directions are relative directions set for the display unit 42 of the user terminal device 40 illustrated in FIGS. 5 to 8. Here, the "left - right direction" is a direction including the "left direction" and the "right direction". The "up - down direction" is a direction including the "up direction" and the "down direction". In each figure, the symbol U shown in the figure indicates the up direction. The symbol D indicates the down direction. The symbol L indicates the left direction. The symbol R indicates the right direction.

[0014] First, referring to FIG. 1, the display data generation system 1 according to this embodiment will be described. The display data generation system 1 is used, for example, in a medical facility such as a hospital. As illustrated in FIG. 1, the display data generation system 1 includes a sensor 10, a bedside monitor 20, a display data generation device 30, and a user terminal device 40.

[0015] Sensor 10 includes a blood pressure sensor 11, a respiration sensor 12, a SpO2 sensor 13, a body temperature sensor 14, and a heart rate sensor 15. However, sensor 10 may include other sensors different from these sensors. The blood pressure sensor 11 acquires a blood pressure signal (an example of a biological signal) indicating the temporal change in the blood pressure (systolic blood pressure, diastolic blood pressure, and mean blood pressure) of the subject. The blood pressure sensor 11 is, for example, a sphygmomanometer or a catheter for obtaining invasive blood pressure values. The respiration sensor 12 acquires a respiration signal (an example of a biological signal) indicating the respiration state such as the respiration rate of the subject. The respiration sensor 12 is, for example, an electrode for obtaining impedance respiration rate. The SpO2 sensor 13 acquires a SpO2 signal (an example of a biological signal) indicating the transcutaneous arterial oxygen saturation (SpO2) of the subject. The SpO2 sensor 13 is, for example, a probe for obtaining SpO2. The body temperature sensor 14 acquires a body temperature signal (an example of a biological signal) indicating the body temperature of the subject. The body temperature sensor 14 is a thermometer for measuring the body temperature of the subject or a body temperature probe connected to the thermometer. The heart rate sensor 15 acquires a heart rate signal (an example of a biological signal) indicating the body temperature of the subject. The heart rate sensor 15 is, for example, an electrode for obtaining the heart rate. In this embodiment, sensor 10 acquires biological signals by a passive method, but may acquire biological signals by an active method. In the measurement of biological signals by the passive method, for example, the biological signals are measured by receiving signals from the object without transmitting signals such as light or electromagnetic waves from sensor 10 to the object. In the measurement of biological signals by the active method, for example, signals are transmitted from sensor 10 to the object, and the biological signal information is measured by receiving the signals reflected by the object or transmitted through the object.

[0016] The bedside monitor 20 is arranged, for example, near the subject wearing sensor 10. The bedside monitor 20 is electrically connected to the sensor 10 and the display data generation device 30 by wire or wirelessly. The bedside monitor 20 includes a receiver 21, a controller 22, an input unit 23, a display unit 24, and a transmitter 25.

[0017] The receiving unit 21 receives various biological signals acquired by the sensor 10. The receiving unit 21 transmits the received biological signals to the control unit 22.

[0018] The control unit 22 includes, as a hardware configuration, memory and a processor. The memory consists of, for example, ROM (Read Only Memory) which stores various computer programs, and RAM (Random Access Memory) which has multiple work areas where various computer programs executed by the processor are stored. The processor is, for example, a CPU (Central Processing Unit) which is configured to load a specified computer program from the various computer programs embedded in the ROM onto the RAM and execute various processes in cooperation with the RAM. For example, the control unit 22 generates various biological information based on various biological signals by having the processor execute computer programs in cooperation with the RAM. Examples of biological information include blood pressure information based on blood pressure signals, respiratory information based on respiratory signals, SpO2 information based on SpO2 signals, body temperature information based on body temperature signals, and heart rate information based on heart rate signals. The control unit 22 transmits the various biological information to the input unit 23.

[0019] The input unit 23 is configured to accept input operations from users such as medical professionals. The user is, for example, a medical professional such as a doctor or nurse. The input unit 23 is, for example, a touch panel superimposed on the display unit 24, or operation buttons mounted on the housing. The user inputs, for example, consciousness information (an example of biological information) regarding the subject's consciousness and oxygen support information (an example of biological information) regarding the need for oxygen support to the input unit 23. For example, if the user confirms that the subject is unconscious, they input consciousness information indicating the subject's unconsciousness to the input unit 23. Also, if the user determines, for example, that oxygen support is necessary for the subject, they input oxygen support information indicating the need for oxygen support to the subject to the input unit 23. In this way, the bedside monitor 20 can acquire not only biological information based on the subject's biological signals acquired by the sensor 10, but also the subject's biological information via the input unit 23.

[0020] The display unit 24 is, for example, a liquid crystal display. The display unit 24 displays, for example, various biological information generated by the control unit 22 and various biological information input to the input unit 23.

[0021] The transmission unit 25 transmits various biological information generated by the control unit 22 and various biological information input to the input unit 23 to the display data generation device 30.

[0022] The display data generation device 30 includes an input interface 31, a storage device 32, a control unit 33, a display unit 34, and an output interface 35. These are communicated with each other via a bus 36.

[0023] The input interface 31 is configured to receive various biometric information transmitted from the bedside monitor 20. In other words, the subject's biometric information is input to the input interface 31. For example, the input interface 31 transmits the input biometric information to the control unit 33.

[0024] The storage device 32 is, for example, a storage device such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or flash memory. The storage device 32 stores, for example, reference information indicating the reference values ​​for each biological information used in qSOFA (quick SOFA) as illustrated in Figure 2, and type information indicating the type of each biological information used in qSOFA. The storage device 32 also stores, for example, reference information indicating the reference values ​​for each biological information used in NEWS (National Early Warning Score) as illustrated in Figure 3, and type information indicating the type of each biological information used in NEWS. qSOFA and NEWS are discrimination methods used to determine whether a subject has sepsis. In other words, the storage device 32 stores discrimination methods for determining the condition of a subject.

[0025] As illustrated in Figure 2, the vital signs used in qSOFA are respiratory rate, systolic blood pressure, and consciousness. If the subject's respiratory rate is 22 breaths per minute or more, the respiratory rate score is 1. On the other hand, if the subject's respiratory rate is less than 22 breaths per minute, the respiratory rate score is 0. If the subject's respiration blood pressure is 100 mmHg or less, the systolic blood pressure score is 1. On the other hand, if the subject's respiration blood pressure is greater than 100 mmHg, the systolic blood pressure score is 0. If the subject is unconscious, the consciousness score is 1. On the other hand, if the subject is conscious, the consciousness score is 0. These scores are added together, and if the combined score is 2 or higher, the subject is likely to have sepsis (i.e., the subject's condition is poor). In this embodiment, for each biological information example shown in Figure 2, the range in which the score is 0 is defined as the normal range of biological information used in qSOFA, and the range outside the normal range (the range in which the score is 1) is defined as the abnormal range of biological information used in qSOFA. In this embodiment, the range in which the subject's respiratory rate per minute is 0 or more and less than 22 is defined as the normal range of respiratory information (respiratory rate) in qSOFA, and the range in which the subject's respiratory rate per minute is 22 or more is defined as the abnormal range of respiratory information in qSOFA. The range in which the subject's reconciliation blood pressure is greater than 100 mmHg and 300 mmHg or less is defined as the normal range of blood pressure information (reconciliation blood pressure) in qSOFA, and the range in which the subject's reconciliation blood pressure is 100 mmHg or less is defined as the abnormal range of blood pressure information in qSOFA. The upper limit of the normal range of blood pressure information (reconciliation blood pressure) is, for example, the maximum value of reconciliation blood pressure obtained from the subject or a value arbitrarily set by the user. Regarding consciousness, a numerical value of 3 indicates consciousness, and a numerical value of 1 indicates unconsciousness. The normal range for consciousness information in qSOFA is 2 or higher and 4 or lower, while the abnormal range for consciousness information in qSOFA is 0 or higher and less than 2.

[0026] As illustrated in Figure 3, the vital signs used in NEWS are respiratory rate, transcutaneous arterial oxygen saturation (SpO2), oxygen support, body temperature, systolic blood pressure, heart rate, and consciousness. For example, if the subject's respiratory rate is 8 breaths per minute or less, or 25 breaths per minute or more, the respiratory rate score is 3. If the respiratory rate is between 21 and 24 breaths per minute, the respiratory rate score is 2. If the respiratory rate is between 9 and 11 breaths per minute, the respiratory rate score is 1. If the respiratory rate is between 12 and 20 breaths per minute, the respiratory rate score is 0. Also, for example, if the subject is unconscious, the consciousness score is 3. On the other hand, if the subject is conscious, the consciousness score is 0. Scores for the remaining parameters are calculated based on reference values ​​established in medical guidelines, etc. The calculated scores are then added together. If the added score is 5 or higher, or if there is one or more vital signs with a score of 3 or higher, the subject is likely to have sepsis (i.e., the subject's condition is poor). In this embodiment, for each biological information example shown in Figure 3, the range where the score is 0 is defined as the normal range of biological information used in NEWS, and the range outside the normal range (the range where the score is between 1 and 3) is defined as the abnormal range of biological information used in NEWS. For example, the range where the subject's respiratory rate per minute is 12 or more and 20 or less is the normal range of respiratory information (respiratory rate) in NEWS, and the range where the subject's respiratory rate per minute is 11 or less or 21 or more is the abnormal range of respiratory information in NEWS. In addition, in this embodiment, the range where the subject's transcutaneous arterial oxygen saturation is 96% or more and 100% or less is the normal range of SpO2 information in NEWS, and the range where the subject's transcutaneous arterial oxygen saturation is less than 96% is the abnormal range of respiratory information in NEWS. Regarding consciousness, consciousness is quantified as 3, and unconsciousness is quantified as 1, and the normal range of consciousness information in NEWS is 2 or more and 4 or less, and the abnormal range of consciousness information in NEWS is 0 or more and less than 2. Regarding oxygen support, a value of 1 indicates that oxygen support is provided, and a value of 3 indicates that oxygen support is not provided. The normal range for oxygen support information in NEWS is 2 or higher and 4 or lower, while the abnormal range for oxygen support information in NEWS is 0 or higher and less than 2.

[0027] Returning to Figure 1, the storage device 32 will be described. The storage device 32 stores various information, such as normal range information indicating the normal range of biological information set for each piece of biological information, abnormal range information indicating the abnormal range of the biological information set for each piece of biological information, and candidate discrimination method information indicating a selectable but unused discrimination method. For example, the storage device 32 transmits the normal range information and the abnormal range information to the control unit 33 based on a control signal from the control unit 33.

[0028] The control unit 33 includes a memory 331 and a processor 332 as its hardware configuration. The memory 331 consists of, for example, a ROM (Read Only Memory) in which various computer programs are stored, and a RAM (Random Access Memory) having multiple work areas in which various computer programs executed by the processor are stored. The processor 332 is, for example, a CPU (Central Processing Unit) which is configured to load a specified computer program from the various computer programs embedded in the ROM onto the RAM and execute various processes in cooperation with the RAM. For example, the control unit 33 realizes various processes by having the processor 332 execute computer programs in cooperation with the RAM.

[0029] The control unit 33 generates condition information indicating the subject's condition based on the biometric information received from the input interface 31 and the discrimination method stored in the storage device 32. After generating the condition information, the control unit 33 generates background information indicating the background corresponding to the subject's condition. The control unit 33 generates display data including the biometric information received from the input interface 31 and the background information. However, the display data may include not only biometric information and background information, but also other information such as normal range information, abnormal range information, condition information, discrimination method information indicating the discrimination method to be used, candidate discrimination method information, and identification information described later. In the display data, the background information is displayed so as to overlap with the biometric information. On the other hand, the condition information is displayed so as not to overlap with the biometric information. The display data includes a first area where biometric information used in the discrimination method for determining the subject's condition is displayed, a second area where biometric information not used in the discrimination method is displayed, and a third area where biometric information acquired at a specific time is displayed.

[0030] The control unit 33 can make the color of the background information display mode and the color of the biological information display mode different. In this embodiment, the color of the background information display mode is lighter than the color of the biological information display mode. The control unit 33 makes the color of the background information display mode lighter than the color of the biological information display mode by, for example, lowering the brightness and saturation of the background information display mode than the brightness and saturation of the biological information display mode. The control unit 33 makes the color of the background information display mode lighter than the color of the biological information display mode by, for example, lowering the brightness of the background information display mode than the brightness of the biological information display mode. The control unit 33 makes the color of the background information display mode lighter than the color of the biological information display mode by, for example, lowering the saturation of the background information display mode than the saturation of the biological information display mode. In this embodiment, the color is determined by the control unit 33 adjusting the RGB gradation. Here, brightness can be determined based on the maximum value of RGB, and saturation can be determined based on the value obtained by subtracting the minimum value of RGB from the maximum value of RGB and dividing the result by the maximum value of RGB. Therefore, when the brightness of the background information is lower than the brightness of the biological information, it means that the maximum RGB value of the background information is smaller than the maximum RGB value of the biological information. Also, when the saturation of the background information is lower than the saturation of the biological information, it means that the value obtained by subtracting the minimum RGB value from the maximum RGB value of the background information and dividing that value by the maximum RGB value is smaller than the value obtained by subtracting the minimum RGB value from the maximum RGB value of the biological information and dividing that value by the maximum RGB value.

[0031] The control unit 33 can make the hue related to the display mode of the condition information different from the hue related to the display mode of the background information. In this embodiment, the hue related to the display mode of the condition information corresponds to the hue related to the display mode of the background information. Note that "the hues correspond" means that the values ​​obtained from the following formulas are the same. When the largest value among RGB is defined as MAX and the smallest value as MIN, When R is at its maximum value, hue H = 60 × ((GB) ÷ (MAX - MIN)). When G is at its maximum value, the hue H = 60 × ((BR) ÷ (MAX - MIN)) + 120. When B is at its maximum value, the hue H = 60 × ((RG) ÷ (MAX - MIN)) + 240. Note that if RGB values ​​are the same, the hue (H) value is 0. Furthermore, the color used for displaying the condition information is darker than the color used for displaying the background information. The color tones for both the condition information display and the background information display are determined by the control unit 33 adjusting the RGB gradation as described above.

[0032] The control unit 33 generates a control signal to cause the control unit 33 to transmit normal range information and abnormal range information corresponding to the biological information received from the input interface 31, and transmits the control signal to the storage device 32. Based on the control signal, the storage device 32 transmits the normal range information and abnormal range information corresponding to the biological information received from the input interface 31 to the control unit 33. In this way, the control unit 33 receives the normal range information and abnormal range information corresponding to the biological information received from the input interface 31 from the storage device 32. The display data generated by the control unit 33 may include normal range information and abnormal range information related to the biological information received from the input interface 31. In this case, the biological information is displayed so as to overlap with the background information and at least one of the normal range information and abnormal range information. Furthermore, the control unit 33 may generate display data such that the color tone related to the display mode of the normal range information is different from the color tone related to the display mode of the abnormal range information. This color tone is also determined by the control unit 33 adjusting the RGB gradation as described above.

[0033] The control unit 33 classifies each piece of biological information input to the input interface 31 into biological information to be used in the discrimination method and biological information not to be used in the discrimination method, based on the discrimination method information and the type information. Based on the discrimination method information and the candidate discrimination method information, the control unit 33 generates identification information to distinguish between the discrimination methods that are used and those that are not.

[0034] When multiple pieces of biological information are input to the input interface 31, the control unit 33 generates unified range information that indicates a unified range based on the normal range information and abnormal range information corresponding to each piece of biological information. The unified range is a range for uniformly defining the normal range and abnormal range of multiple pieces of biological information. The multiple pieces of biological information input to the input interface 31 are displayed together within the unified range in the display data generated by the control unit 33.

[0035] Computer programs can be supplied to a computer, for example, by being stored in various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memory (e.g., mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs), etc.

[0036] The display unit 34 is, for example, a touchscreen type display such as a liquid crystal display or an organic EL display. The display unit 34 displays, for example, display data received from the control unit 33.

[0037] The output interface 35 outputs the display data received from the control unit 33 to the user terminal device 40. For example, the output interface 35 outputs an output signal OS corresponding to the display data to the user terminal device 40. The output interface 35 may, if necessary, include a circuit to convert the output data into an output signal OS that the user terminal device 40 can process.

[0038] The user terminal device 40 is, for example, an electronic device such as a desktop PC, notebook PC, tablet terminal, or smartphone. The user terminal device 40 includes an input unit 41 and a display unit 42.

[0039] The input unit 41 is configured to accept input operations from users such as medical professionals. The input unit 41 is, for example, a touch panel placed on top of the display unit 42, or operation buttons attached to the housing. The user inputs identification method information indicating the identification method to be used, and selected time information indicating a specific time when the biometric information should be checked, into the input unit 41. The input unit 41 transmits the identification method information, selected time information, etc., entered by the user to the display data generation device 30.

[0040] The display unit 42 is, for example, a liquid crystal display. The display unit 42 is configured to display, for example, display data output from the output interface 35.

[0041] (First example) Next, the method for generating display data in this embodiment will be described with reference to Figures 4 to 6. Figure 4 is a flowchart of the display data generation method according to this embodiment. In this embodiment, the current time is 18:30 on December 10, 2022, and the display data generation method illustrated in Figure 4 is assumed to have been executed at 18:30 on December 10, 2022. In this embodiment, each biometric information is assumed to have been acquired between 16:00 and 18:30 on December 10, 2022. Furthermore, in this embodiment, it is assumed that selected time information indicating that the time at which the biometric information is to be checked is 17:52 on December 10, 2022 has been input to the input unit 41 of the user terminal device 40. In other words, the specific time selected by the user in this embodiment is 17:52 on December 10, 2022.

[0042] In this embodiment, the respiratory rate, transcutaneous arterial oxygen saturation, body temperature, systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, oxygen support, consciousness, qSOFA-based score, and NEWS-based score of the subject at 17:52 and 18:30 on December 10, 2022, are shown in Table 1. [Table 1]

[0043] As illustrated in Figure 4, the sensor 10 acquires the subject's biological signals (STEP 01). In this embodiment, the sensor 10 acquires respiratory signals, SpO2 signals, body temperature signals, blood pressure signals, and heart rate signals. The various biological signals acquired by the sensor 10 are transmitted to the receiving unit 21 of the bedside monitor 20.

[0044] The bedside monitor 20 acquires various biological information (STEP 02). In this embodiment, oxygen support information and consciousness information are input to the input unit 23 by the user. Therefore, the bedside monitor 20 acquires respiratory information, SpO2 information, body temperature information, blood pressure information, and heart rate information generated by the control unit 22 based on the respiratory signal, SpO2 signal, body temperature signal, blood pressure signal, and heart rate signal received via the receiving unit 21. The bedside monitor 20 also acquires oxygen support information and consciousness information via the input unit 23. The transmitting unit 25 of the bedside monitor 20 transmits the various biological information generated by the control unit 22 and the various biological information input to the input unit 23 to the input interface 31 of the display data generation device 30.

[0045] Various biometric information transmitted from the transmission unit 25 of the bedside monitor 20 is input to the input interface 31 (STEP 03). The input interface 31 transmits the input biometric information to the control unit 33.

[0046] Discrimination method information indicating the discrimination method to be used is input to the input unit 41 of the user terminal device 40 (STEP 04). For example, the user inputs discrimination method information indicating that the discrimination method to be used is qSOFA into the input unit 41 of the user terminal device 40. Input of discrimination method information into the input unit 41 is performed, for example, by tapping the discrimination method to be used on the touch panel superimposed on the display unit 42. The user terminal device 40 transmits the discrimination method information input to the input unit 41 to the display data generation device 30.

[0047] The control unit 33 classifies each piece of biological information input to the input interface 31 into biological information to be used in the discrimination method and biological information not to be used in the discrimination method, based on the discrimination method information received from the user terminal device 40 and the type information stored in the storage device 32 (STEP 05). If the discrimination method to be used is, for example, qSOFA, the biological information to be used in the discrimination method is respiratory information, blood pressure information, and consciousness information, and the biological information not to be used in the discrimination method is SpO2 information, body temperature information, heart rate information, and oxygen support information. In STEP 05, the control unit 33 generates identification information based on the discrimination method information and candidate discrimination method information.

[0048] The control unit 33 generates condition information indicating the subject's condition based on the biological information received from the input interface 31 and the reference information stored in the storage device 32 (STEP 06). When the discrimination method used is qSOFA, the control unit 33 generates condition information based on respiratory information, blood pressure information, consciousness information, and reference information related to qSOFA. Here, as an example, we will describe the case in which the control unit 33 generates condition information indicating the subject's condition at the current time. In this embodiment, the subject's respiratory rate at the current time is 12 breaths per minute. The subject's systolic blood pressure at the current time is 100. The subject is conscious at the current time. Therefore, the control unit 33 generates condition information indicating that the score based on qSOFA at the current time is 1.

[0049] The control unit 33 generates biometric information used in a discrimination method to determine the subject's condition and background information indicating the background corresponding to the subject's condition determined based on the discrimination method (STEP 07). For example, when determining the subject's condition based on qSOFA at the current time, the control unit 33 generates background information indicating the background corresponding to the score based on qSOFA at the current time (i.e., 1).

[0050] The control unit 33 generates a control signal to send normal range information and abnormal range information corresponding to the biological information received from the input interface 31 to the control unit 33, and sends the control signal to the storage device 32. As a result, the control unit 33 receives the normal range information and abnormal range information corresponding to each piece of biological information (STEP 08).

[0051] The control unit 33 generates unified range information that indicates a unified range based on the normal range information and abnormal range information corresponding to each piece of biological information (STEP 09). In this embodiment, the control unit 33 generates unified range information that indicates a unified range based on the normal range information and abnormal range information corresponding to the biological information used in the discrimination method, and unified range information that indicates a unified range based on the normal range information and abnormal range information corresponding to the biological information not used in the discrimination method.

[0052] First, we will explain the unified range information, which shows a unified range based on the normal range information and abnormal range information corresponding to the biological information used in the discrimination method. Here, we will explain assuming that qSOFA is used as the discrimination method. The normal range for respiratory rate per minute corresponding to respiratory information is 0 or more and less than 22, and the abnormal range for respiratory rate per minute corresponding to respiratory information is 22 or more. The normal range for systolic blood pressure corresponding to blood pressure information is greater than 100 mmHg and 300 mmHg or less, and the abnormal range for systolic blood pressure corresponding to blood pressure information is 100 mmHg or less. The normal range for consciousness corresponding to consciousness information is 2 or more and 4 or less, and the abnormal range for consciousness corresponding to consciousness information is 0 or more and less than 2. The control unit 33 generates unified range information that shows a unified range based on the normal range information and abnormal range information corresponding to respiratory information, blood pressure information, and consciousness information. The control unit 33 calculates the median of the upper and lower limits in the normal range of each biological information, divides the upper and lower limits in the normal range of each biological information by the median corresponding to each biological information, and then multiplies by the largest median to generate the unified range information. In other words, the control unit 33 corrects the normal ranges of each biological information, which are originally different numerical ranges, as described above, thereby aligning the display position of the normal range for each biological information and setting a unified range. In this embodiment, the median of the upper and lower limits in the normal range of respiratory information is 11. The median of the upper and lower limits in the normal range of blood pressure information is 200 mmHg. The median of the upper and lower limits in the normal range of consciousness information is 3. The control unit 33 generates unified range information by multiplying the upper and lower limits in the normal range of respiratory information by 200 / 11 and the upper and lower limits in the normal range of consciousness information by 200 / 3. At this time, the control unit 33 also multiplies the number of breaths indicated by the acquired respiratory information by 200 / 11 and the numerical value corresponding to the acquired consciousness information by 200 / 3.

[0053] Next, we will explain the unified range information, which indicates a unified range based on normal range information and abnormal range information corresponding to biological information not used in the discrimination method. In this embodiment, when qSOFA is used, the normal range of biological information not used in qSOFA (SpO2 information, body temperature information, heart rate information, and oxygen supplementation information) shall be the same as the normal range and abnormal range of each biological information in NEWS. That is, for example, the normal range for body temperature information is 36.1 degrees Celsius or more and 38.0 degrees Celsius or less, and the abnormal range for body temperature information is 36.0 degrees Celsius or less or 38.1 degrees Celsius or more. The control unit 33 generates unified range information, which indicates a unified range based on normal range information and abnormal range information corresponding to SpO2 information, body temperature information, heart rate information, and oxygen supplementation information, according to the principle described above.

[0054] As illustrated in Figure 4, the control unit 33 determines whether a specific time for checking biometric information has been selected (STEP 10). When a user selects a specific time for checking biometric information, they input selected time information indicating the specific time into the input unit 41 of the user terminal device 40. When the selected time information is input into the input unit 41 of the user terminal device 40, the user terminal device 40 transmits the selected time information input into the input unit 41 to the display data generation device 30. If the display data generation device 30 receives the selected time information from the user terminal device 40, the control unit 33 determines that a specific time for checking biometric information has been selected (YES in STEP 10) and executes STEP 11. On the other hand, if the display data generation device 30 has not received the selected time information from the user terminal device 40, the control unit 33 determines that a specific time for checking biometric information has not been selected (NO in STEP 10) and executes STEP 12. In this embodiment, December 10, 2022, 17:52 is selected as the specific time for checking the biological information (YES in STEP 10), so the control unit 33 executes STEP 11.

[0055] The control unit 33 identifies all biological information acquired at a specific time selected by the user (STEP 11). In this embodiment, the specific time selected by the user is 17:52 on December 10, 2022, so all biological information acquired at 17:52 on December 10, 2022 (respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information) is identified.

[0056] The control unit 33 identifies the display area for each piece of biological information (STEP 12). Specifically, the control unit 33 identifies a first area as the display area for biological information used in the discrimination method, a second area as the display area for biological information not used in the discrimination method, and a third area as the display area for biological information acquired at a specific time arbitrarily selected by the user. If the discrimination method used is, for example, qSOFA, the display area for respiratory information, blood pressure information, and consciousness information acquired from 16:00 on December 10, 2022 to the present time is the first area. The display area for SpO2 information, body temperature information, heart rate information, and oxygen support information acquired from 16:00 on December 10, 2022 to the present time is the second area. The display area for respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information acquired at 17:52 on December 10, 2022 is the third area.

[0057] The control unit 33 generates display data including biological information, background information, normal range information, abnormal range information, condition information, discrimination method information, candidate discrimination method information, and identification information (STEP 13). The control unit 33 transmits the generated display data to the display unit 34 and / or output interface 35. When the display data is transmitted to the output interface 35, the output interface 35 outputs the received display data to the user terminal device 40. In this embodiment, it is assumed that the display data is transmitted to the output interface 35 and output to the user terminal device 40.

[0058] When display data is output to the user terminal device 40, the display data is displayed on the display unit 42 of the user terminal device 40 (STEP 14). At this time, the display unit 42 of the user terminal device 40 displays the display data exemplified in Figure 5 or Figure 6. The display data exemplified in Figure 5 is the display data displayed on the display unit 42 when qSOFA is used. The display data exemplified in Figure 6 is the display data displayed on the display unit 42 when NEWS is used.

[0059] First, we will explain the display data shown on the display unit 42 when qSOFA is used as the discrimination method. As illustrated in Figure 5, the display data includes regions R1 to R9. Region R1 displays the subject's biological information (respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information) as of the current time, December 10, 2022, 18:30.

[0060] In region R2, located below region R1, a discrimination method for determining the subject's condition is displayed. In this embodiment, qSOFA and NEWS are displayed in region R2. In this embodiment, the discrimination method used is qSOFA, so qSOFA is the discrimination method indicated by the discrimination method information, and NEWS is the discrimination method indicated by the candidate discrimination method information. Near the text of the discrimination method to be used, as indicated by the discrimination method information, identification information is displayed to distinguish between the discrimination method being used and the discrimination method that is not being used. In the example shown in Figure 5, since qSOFA is used, a line L1 is displayed near the text "qSOFA" as identification information indicating that qSOFA is being used. The line L1 is displayed below the text "qSOFA".

[0061] Region R3, located below region R2, displays the score based on the discrimination method used as condition information at 18:30 on December 10, 2022. In the example shown in Figure 5, the discrimination method used is qSOFA, and the score based on qSOFA at 18:30 on December 10, 2022 is 1, so "1" is displayed in region R3.

[0062] In area R4, located to the right of area R3, a message corresponding to the determination result of the control unit 33 at the current time is displayed. In the example shown in Figure 5, the message "Condition is good, but please pay attention to blood pressure" is displayed in area R4. Note that the information displayed in area R4 is not limited to messages; for example, a color corresponding to the determination result of the control unit 33 at the current time may also be displayed.

[0063] In area R5, located below areas R3 and R4, condition information based on the discrimination method used, from 16:00 on December 10, 2022 to the present time, is displayed in the form of a bar graph. In the example shown in Figure 5, area R5 displays a bar graph corresponding to the qSOFA-based score from 16:00 on December 10, 2022 to the present time. In this embodiment, if the qSOFA score is 1, the bar graph is colored yellow, and if the qSOFA-based score is 2 or higher, the bar graph is colored red. In Figure 5, bar graphs with vertical hatching indicate that they are colored yellow. The bar graphs are arranged chronologically, with the bar graph on the left representing condition information that is earlier in time than the bar graph on the right.

[0064] In area R6, located below area R5, the vital signs information used for the discrimination method (the discrimination method indicated by the discrimination method information) from 16:00 on December 10, 2022 to the present time is displayed in the form of a vital signs graph extending along the time axis. Therefore, area R6 is an example of the first area. In the example shown in Figure 5, the vital signs information (respiratory information, blood pressure information, and consciousness information) used by qSOFA from 16:00 on December 10, 2022 to the present time is displayed in area R6 in the form of a vital signs graph extending along the time axis. The vital signs graph showing respiratory information is graph G1. The vital signs graph showing blood pressure information is graph G2. The vital signs graph showing consciousness information is graph G3. Graphs G1 to G3 are displayed so as not to overlap with the bar graph of condition information displayed in area R5. The time axes in areas R5 and R6 coincide, and graphs G1 to G3 and the bar graph of condition information are displayed correspondingly along that time axis.

[0065] In region R6, background information corresponding to the subject's condition, as determined based on biological information and discrimination methods, is displayed so as to overlap with graphs G1-G3. In other words, the background information is displayed so as to overlap with the biological information. The background information in region R6 coincides with the time axis of the condition information in region R5. The background corresponding to the background information at a given time is colored with a hue that corresponds to the hue of the color used in the bar graph of the condition information at the same time, but is lighter than the color used in the bar graph. In other words, at least one of the brightness and saturation related to the display method of the condition information is higher than at least one of the brightness and saturation related to the display method of the background information. Note that this specification does not intend to compare the brightness related to the display method of the condition information with the saturation related to the display method of the background information, or the saturation related to the display method of the condition information with the brightness related to the display method of the background information. In the example shown in Figure 5, the background information at the time when the qSOFA score is 1 is colored light yellow. For the sake of explanation, in Figure 5, the thickness of the hatching lines represents the brightness and / or saturation (i.e., the intensity of the color) of the colored color. The thicker the hatching lines, the higher the brightness and / or saturation (i.e., the intensity of the color) of the colored color. This is also true for the display data exemplified in Figures 6 and 7. Thus, the hue of the display mode of the background information differs from the hue of the display mode of the condition information. Furthermore, in this embodiment, the color of the display mode of the background information is lighter than the color of the display mode of graphs G1 to G3. In other words, at least one of the brightness and saturation of the display mode of the background information is lower than at least one of the brightness and saturation of the display mode of graphs G1 to G3. Note that this specification does not intend to compare the brightness of the display mode of the background information with the saturation of the display mode of graphs G1 to G3, or vice versa. For the sake of explanation, in Figure 5, the thickness of the lines represents the lightness and / or saturation (i.e., the intensity of the color) of the colored color. The thicker the line, the higher the lightness and / or saturation (i.e., the more intense the color).In other words, the color scheme related to the display of background information is different from the color scheme related to the display of graphs G1 to G3.

[0066] Region R6 includes region R61, which corresponds to the normal range of the biological information used in the discrimination method, and regions R62 and R63, which correspond to the abnormal range of the biological information used in the discrimination method. In the example shown in Figure 5, the normal and abnormal ranges of the biological information used in the discrimination method are uniformly defined by the unified range U1 indicated by the unified range information generated by the control unit 33 according to the principle described above. Specifically, in region R6, multiple biological information (graphs G1 to G3) are displayed together in the unified range U1. In other words, in region R6, the display position of the normal range for each biological information used in the discrimination method is consistent. To put it another way, in region R6, the normal range for each biological information used in the discrimination method is consistent on the vertical axis of region R6 (the axis extending vertically in Figure 5). Graphs G1 to G3 are displayed so as to overlap with region R61 or region R63. Therefore, the biological information is displayed so as to overlap with at least one of the normal range information and the abnormal range information. The color of region R61 is different from the color of regions R62 and R63. In other words, the color of the display mode for normal range information is different from the color of the display mode for abnormal range information. In this embodiment, the color of region R61 is gray, and the colors of regions R62 and R63 are black. In other words, the color of the display mode for normal range information is lighter than the color of the display mode for abnormal range information. To put it another way, at least one of the brightness and saturation of the display mode for normal range information is smaller than at least one of the brightness and saturation of the display mode for abnormal range information. Note that this specification does not intend to compare the brightness of the display mode for normal range information with the saturation of the display mode for abnormal range information, or the saturation of the display mode for normal range information with the brightness of the display mode for abnormal range information. For the sake of explanation, in Figure 5, the presence or absence of dot hatching is used to show that the color of the display mode for normal range information is different from the color of the display mode for abnormal range information. This point is also true for the display data illustrated in Figures 6 and 7.

[0067] In region R7, located below region R6, vital signs information from December 10, 2022, at 16:00 to the present time that is not used in the discrimination method is displayed in the form of a vital signs graph extending along a time axis. Therefore, region R7 is an example of a second region. In this embodiment, vital signs information not used by qSOFA from December 10, 2022, at 16:00 to the present time (SpO2 information, body temperature information, heart rate information, and oxygen supplementation information) is displayed in region R7 in the form of a vital signs graph extending along a time axis. The vital signs graph showing SpO2 information is graph G4. The vital signs graph showing body temperature information is graph G5. The vital signs graph showing heart rate information is graph G6. The vital signs graph showing oxygen supplementation information is graph G7. The time axes in region R6 and region R7 coincide. That is, the time axes in region R5, region R6, and region R7 all coincide.

[0068] Region R7 includes Region R71, which corresponds to the normal range of biological information not used in the discrimination method, and Regions R72 and R73, which correspond to the abnormal range of biological information used in the discrimination method. In the example shown in Figure 5, the normal and abnormal ranges of biological information not used in the discrimination method are defined by the unified range U2 indicated by the unified range information generated by the control unit 33 according to the principle described above. Therefore, in Region R7, multiple biological information (graphs G4 to G7) are displayed together in the unified range U2. In other words, in Region R7, the display position of the normal range for each biological information not used in the discrimination method is consistent. To put it another way, in Region R7, the normal range for each biological information not used in the discrimination method is consistent on the vertical axis of Region R7 (the axis extending vertically in Figure 5). Also, the color of Region R71 is different from the color of Regions R72 and R73. In other words, the color of the display mode of the normal range information is different from the color of the display mode of the abnormal range information. In this embodiment, the color of region R71 is gray, and the colors of regions R62 and R63 are black. Furthermore, in region R7, similar to region R6, the presence or absence of dot hatching indicates that the color scheme related to the display of normal range information differs from the color scheme related to the display of abnormal range information.

[0069] Regions R5, R6, and R7 display a straight line L2 that traverses these regions. Line L2 indicates the position on the time axis in regions R5, R6, and R7 where the specific time indicated by the selected time information (in this embodiment, 17:52 on December 10, 2022) corresponds.

[0070] Region R8, located below region R7, displays the subject's vital signs (respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information) as of 17:52 on December 10, 2022. Therefore, region R8 is an example of a third region.

[0071] Region R9, located to the left of region R8, displays the status information of the discrimination method used as of December 10, 2022, at 17:52, showing the score based on the discrimination method being used. In this embodiment, the discrimination method used is qSOFA, and the score based on qSOFA as of December 10, 2022, at 17:52 is 0, so "0" is displayed in region R9.

[0072] Regions R3 and R5 are located above regions R6 and R8. Therefore, the score displayed in region R3 (an example of condition information) and the bar graph displayed in region R5 (an example of condition information) are displayed above graphs G1-G7 (i.e., biometric information used in the discrimination method and biometric information not used in the discrimination method). Graphs G1-G3 (i.e., biometric information used in the discrimination method) are displayed above graphs G4-G7 (i.e., biometric information not used in the discrimination method). In addition, the score displayed in region R3 and the bar graph displayed in region R5 are displayed above the overlapping portion of graphs G1-G7 and background information in region R6.

[0073] Next, we will explain the display data displayed on the display unit 42 when NEWS is used as the discrimination method. For example, when a user taps NEWS, which is the discrimination method indicated by the candidate discrimination method information, on the touch panel superimposed on the display unit 42 of the user terminal device 40, a screen with the display data exemplified in Figure 6 is displayed on the display unit 42. In other words, when a user performs an operation on the user terminal device 40 to switch the discrimination method to be used to the discrimination method selected by the user, the user terminal device 40 sends a switching request signal to the display data generation device 30. Based on the switching request signal, the display data generation device 30 switches the discrimination method to be used to the selected discrimination method. In this way, when the discrimination method indicated by the candidate discrimination method information is selected, the discrimination method indicated by the selected candidate discrimination method information (i.e., NEWS) and the discrimination method indicated by the discrimination method information (i.e., qSOFA) are switched. As exemplified in Figure 6, the content displayed in area R1 when NEWS is used is the same as the content displayed in area R1 when qSOFA is used.

[0074] The content displayed in area R2 when using NEWS is basically the same as the content displayed in area R2 when using qSOFA. However, in the example shown in Figure 6, line L1 is displayed below the word "NEWS".

[0075] The content displayed in area R3 when using NEWS is basically the same as the content displayed in area R3 when using qSOFA. However, in the example shown in Figure 6, the discrimination method used is NEWS, and the score based on NEWS as of 18:30 on December 10, 2022 is 2, so "2" is displayed in area R3.

[0076] The content displayed in area R4 when using NEWS is the same as the content displayed in area R4 when using qSOFA.

[0077] The content displayed in area R5 when using NEWS is basically the same as the content displayed in area R5 when using qSOFA. However, in the example shown in Figure 6, the score based on NEWS for the time period from 16:00 on December 10, 2022 to the present time is displayed in area R5. In this embodiment, if the NEWS score is 1, the corresponding bar graph is colored blue. If the score based on NEWS is 2, the corresponding bar graph is colored green. If the score based on NEWS is 3 and there is no biometric information with a score of 3 or higher, the corresponding bar graph is colored yellow. If the score based on NEWS is 4 and there is no biometric information with a score of 3 or higher, the corresponding bar graph is colored orange. If the score based on NEWS is 5 or there is one or more biometric pieces of information with a score of 3 or higher, the corresponding bar graph is colored red. Note that in Figure 6, bar graphs with diagonal hatching are colored blue. Bar graphs with vertical hatching are colored green. Bar graphs with horizontal hatching indicate that the bars are colored yellow.

[0078] When using NEWS, the content displayed in area R6 is basically the same as when using qSOFA. However, in the example shown in Figure 6, the vital information used in NEWS (respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen supplementation information, and consciousness information) acquired from 16:00 on December 10, 2022 to the present time is displayed in area R6 in the form of a vital graph extending along the time axis. The vital graph showing respiratory information is graph G11. The vital graph showing blood pressure information is graph G12. The vital graph showing consciousness information is graph G13. The vital graph showing SpO2 information is graph G14. The vital graph showing body temperature information is graph G15. The vital graph showing heart rate information is graph G16. The vital graph showing oxygen supplementation information is graph G17. In this embodiment as well, the color related to the display method of condition information is darker than the color related to the display method of background information. In other words, at least one of the brightness and saturation related to the display mode of the condition information is higher than at least one of the brightness and saturation related to the display mode of the background information. Also, the color related to the display mode of the background information is lighter than the color related to the display mode of graphs G1 to G3. In other words, at least one of the brightness and saturation related to the display mode of the background information is lower than at least one of the brightness and saturation related to the display mode of graphs G11 to G17.

[0079] The content displayed in region R7 when using NEWS is basically the same as the content displayed in region R7 when using qSOFA. However, in this embodiment, all biological information (respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information) input to the input interface 31 is biological information used for NEWS, so in the example shown in Figure 6, no biological information is displayed in region R7.

[0080] The content displayed in area R8 when using NEWS is the same as the content displayed in area R8 when using qSOFA.

[0081] The content displayed in area R9 when using NEWS is basically the same as the content displayed in area R9 when using qSOFA. However, in the example shown in Figure 6, the discrimination method used is NEWS, and the score based on NEWS at 17:52 on December 10, 2022 is 3, so "3" is displayed in area R3.

[0082] Incidentally, methods for determining a subject's condition include, for example, the NEWS (National Early Warning Score). When determining a subject's condition using such a method, the condition information based on the method and the biometric information used in the method may be displayed on a biometric information monitor or similar device. However, if it is desired to evaluate the subject's condition more comprehensively and / or in more detail, it may be necessary to check not only the biometric information used in the method but also other biometric information not used in that method. Thus, when determining a subject's condition using a method such as NEWS, there is a need to check not only the biometric information necessary for performing the method but also biometric information that is not necessary.

[0083] According to the display data generation device 30 with the above configuration, the biological information used in the discrimination method for determining the subject's condition is displayed in area R6 (an example of the first area), and the biological information not used in the discrimination method is displayed in area R7 (an example of the second area). In other words, the area in which the biological information used in the discrimination method is displayed is different from the area in which the biological information not used in the discrimination method is displayed. Therefore, the display data generation device 30 can distinguish between and display the biological information used in the discrimination method for determining the subject's condition and the biological information not used in the discrimination method. Furthermore, the same effect can be achieved with the display data generation method, computer program, and non-temporary computer-readable medium with the above configuration.

[0084] Furthermore, according to the display data generation device 30 with the above configuration, in regions R6 and R7, multiple biological information is displayed together in a unified range that uniformly defines the normal and abnormal ranges of the multiple biological information. In other words, in regions R6 and R7, multiple biological information is displayed together in a unified range. Therefore, with the display data generation device 30, the user can easily view multiple biological information with minimal eye movement, thus reducing the burden on the user.

[0085] Furthermore, according to the display data generation device 30 with the above configuration, biometric information acquired at a specific time arbitrarily selected is displayed in region R8 (an example of the third region). Therefore, by viewing the biometric information displayed in region R8, the user can confirm not only the vital graph of biometric information extending along the time axis, but also the biometric information at a specific time.

[0086] Furthermore, with the display data generation device 30 according to the above configuration, all biological information acquired at a specific time is displayed in area R8, so the user can comprehensively infer the subject's condition by visually inspecting the biological information displayed in area R8.

[0087] Furthermore, according to the display data generation device 30 with the above configuration, the display data includes condition information indicating the subject's condition. Therefore, by using such display data, the user can confirm not only the biological information used in the discrimination method and biological information not used in the discrimination method, but also the subject's condition. As a result, the user can comprehensively understand the subject's condition.

[0088] Furthermore, according to the display data generation device 30 with the above configuration, condition information is displayed above the biological information used in the discrimination method and the biological information not used in the discrimination method, and the biological information used in the discrimination method is displayed above the biological information not used in the discrimination method. Therefore, the user can check the condition information, the biological information used in the discrimination method, and the biological information not used in the discrimination method in that order, so the condition of the subject can be checked efficiently.

[0089] Furthermore, according to the display data generation device 30 with the above configuration, the display data includes discrimination method information indicating the discrimination method to be used, and the area R6 displays the biological information used in the discrimination method indicated by the discrimination method information. Since the user can intuitively recognize the biological information used in the discrimination method by visually inspecting the discrimination method, the user can easily and quickly recognize the biological information displayed in the first area by using such discrimination method information.

[0090] Furthermore, according to the display data generation device 30 with the above configuration, the display data includes candidate discrimination method information indicating selectable discrimination methods that are not currently in use. Therefore, users can easily recognize selectable discrimination methods by using the candidate discrimination method information.

[0091] Furthermore, with the display data generation device 30 according to the above configuration, when a discrimination method indicated by the candidate discrimination method information is selected, the discrimination method indicated by the selected candidate discrimination method information and the discrimination method indicated by the discrimination method information are switched, so that the discrimination method can be switched easily and quickly.

[0092] (Second embodiment) Next, the method for generating display data in this embodiment will be described with reference to Figures 4 and 7. In this embodiment, parts similar to those in the first embodiment are denoted by the same reference numerals, and detailed explanations are omitted as appropriate. In this embodiment as well, the display data generation method illustrated in Figure 4 is performed. In this embodiment as well, the current time is assumed to be 18:30 on December 10, 2022. Furthermore, in this embodiment as well, it is assumed that each biometric information was acquired between 16:00 on December 10, 2022 and 18:30 on December 10, 2022.

[0093] Steps 01 to 06 are the same as in the first embodiment. In step 04, the user is assumed to have entered identification method information indicating that the identification method to be used is qSOFA into the input unit 41 of the user terminal device 40.

[0094] The control unit 33 generates unified range information for biological information not used in qSOFA (SpO2 information, body temperature information, heart rate information, and oxygen support information) (STEP 08). In this embodiment, unified range information is not generated for biological information used in qSOFA (respiratory information, blood pressure information, and consciousness information). The method for generating unified range information in this embodiment is the same as the method for generating unified range information in the first embodiment, so a detailed explanation is omitted.

[0095] Steps 09 to 14 are the same as in the first embodiment. In step 10, the user enters selected time information into the input unit 41 of the user terminal device 40, indicating that the time at which they wish to check their biometric information is 17:52 on December 10, 2022.

[0096] Here, the display data shown on the display unit 42 of the user terminal device 40 in STEP 14 will be described. In this embodiment, the display data shown on the display unit 42 of the user terminal device 40 is the display data exemplified in Figure 7. In this embodiment, the contents displayed in regions R1 to R5 and regions R7 to R9 are the same as the contents displayed in regions R1 to R5 and regions R7 to R9 in the first embodiment. On the other hand, in the display data of this embodiment, regions R6A to R6C are displayed instead of region R6. A vital graph G21 of respiratory information is displayed in region R6A. A vital graph G22 of blood pressure information is displayed in region R6B. A vital graph G23 of consciousness information is displayed in region R6A. Regions R6A, R6B, and R6C are examples of the first region. Thus, this embodiment differs from the first embodiment in that biological information not used in the discrimination method is displayed together in a unified range U2, but biological information used in the discrimination method is displayed separately (i.e., not displayed together in a unified range).

[0097] In the second embodiment as well, the display data generation device 30 can achieve the same effects as in the first embodiment.

[0098] Furthermore, according to the display data generation device 30 with the above configuration, in region R7 (an example of the second region), multiple biological information items are displayed together in a unified range U2. Biological information that is not used in the discrimination method for determining the condition of the subject has a relatively lower priority for confirmation compared to the biological information used in the discrimination method. According to the display data generation device 30, the biological information displayed in region R7 is biological information that is not used in the discrimination method for determining the condition of the subject, so the user can efficiently view the biological information.

[0099] The embodiments described above are provided to facilitate understanding of this disclosure and do not limit it. This disclosure may be modified or improved without departing from its intent.

[0100] In the above embodiment, area R8 (an example of a third area) displays respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information acquired at 17:52 on December 10, 2022 (an example of a specific time arbitrarily selected by the user), but this disclosure is not limited to this example. Area R8 may display, for example, only the biometric information used in the discrimination method used from among the biometric information acquired at a specific time arbitrarily selected by the user. For example, if the discrimination method used is qSOFA, the display data displayed on the display unit 42 of the user terminal device 40 is the display data exemplified in Figure 8. The display data exemplified in Figure 8 differs from the display data exemplified in Figure 5 in that area R8 displays only respiratory information, blood pressure information, and consciousness information, which are biometric information used in qSOFA. When the display data generation device 30 generates the display data exemplified in Figure 8, area R8 displays only the biometric information used in the discrimination method for determining the condition of the subject from among the biometric information acquired at a specific time. Therefore, by visually inspecting the biometric information displayed in area R8, users can quickly recognize the biometric information used in the discrimination method.

[0101] In the above embodiment, the display data is shown on the display unit 42 of the user terminal device 40, but it may also be shown on the display unit 34 of the display data generation device 30 or the display unit 24 of the bedside monitor 20, for example.

[0102] In the above embodiment, the display data includes biological information, background information, normal range information, abnormal range information, condition information, discrimination method information, candidate discrimination method information, and identification information, but this disclosure is not limited to this example. The display data may not include, for example, background information, normal range information, abnormal range information, condition information, discrimination method information, candidate discrimination method information, and identification information.

[0103] In the above embodiment, multiple pieces of biometric information are input to the input interface 31, but one piece of biometric information may also be input.

[0104] In the second embodiment, the biological information used in the discrimination method is displayed separately, while the biological information not used in the discrimination method is displayed together in a unified range U2. However, the disclosure is not limited to this example. For example, all acquired biological information (i.e., the biological information used in the discrimination method and the biological information not used in the discrimination method) may be displayed in separately separated areas. Alternatively, for example, the biological information used in the discrimination method may be displayed together in a unified range U1, while the biological information not used in the discrimination method may be displayed in separately separated areas.

[0105] In the above embodiment, the input interface 31 receives respiratory information, SpO2 information, body temperature information, blood pressure information, heart rate information, oxygen support information, and consciousness information. However, for example, only biological information used in the discrimination method used may be input.

[0106] In the first embodiment, for example, when the discrimination method used is qSOFA, three pieces of biometric information are displayed in the unified range U1 of region R6, and four pieces of biometric information are displayed in the unified range U2 of region R7. However, the number of biometric information displayed in the unified ranges U1 and U2 only needs to be two or more, and is not limited to this example.

[0107] In the above embodiment, two discrimination methods (qSOFA and NEWS) are displayed in region R2, but for example, three or more discrimination methods may be displayed.

[0108] In the above embodiment, the display data generation system 1 includes a sensor 10, a bedside monitor 20, a display data generation device 30, and a user terminal device 40. However, for example, the display data generation device 30 and the user terminal device 40 may not be included. In this case, the bedside monitor 20 may include a storage device and a control unit 22 corresponding to the storage device 32 and control unit 33 of the display data generation device 30, and the bedside monitor 20 may implement the functions of the display data generation device 30. Alternatively, the display data generation system 1 may not include a bedside monitor 20 and a display data generation device 30. In this case, the user terminal device 40 may include a storage device and a control unit corresponding to the storage device 32 and control unit 33 of the display data generation device 30, and the user terminal device 40 may implement the functions of the display data generation device 30.

[0109] In the above embodiment, the display data is generated by the display data generation device 30, but it may also be generated by the bedside monitor 20 or the user terminal device 40. In this case, the bedside monitor 20 or the user terminal device 40 includes, for example, a control unit corresponding to the display data generation device 30, and acquires various information from the storage device 32 of the display data generation device 30.
