Description

[Technical Field]

[0001] The present invention relates to a biometric information storage system and a biometric information storage program. [Background technology]

[0002] Patent Document 1 discloses a system and method for predicting and summarizing medical events from electronic health records. Like the system disclosed in Patent Document 1, there is a demand for a system that supports medical professionals by, for example, predicting medical events from electronic health records, automatically recording electronic health records, and predicting event risks from electronic health records.

[0003] For example, in surgeries using various devices such as a heart-lung machine, an anesthesiologist first administers anesthesia to the patient. Next, medical professionals such as doctors and nurses prepare for the surgery, while a clinical engineer prepares for extracorporeal circulation. Once the doctor begins the surgery, the anesthesiologist is primarily responsible for managing the patient's vital signs until extracorporeal circulation begins. Once a cannula is inserted and preparations for extracorporeal circulation are complete, the clinical engineer begins extracorporeal circulation at the doctor's direction. When extracorporeal circulation using a heart-lung machine is in progress, the clinical engineer is often also responsible for managing the patient's vital signs and condition during circulation. Next, when the doctor stops the operation of the heart-lung machine, the anesthesiologist makes adjustments to wean the patient off the machine. For example, during such a surgical procedure, medical personnel such as doctors, clinical engineers, anesthesiologists, and nurses communicate with each other to record vital indicators such as the patient's heart rate, pulse rate, respiratory rate, blood pressure, body temperature, hematocrit (Ht) and hemoglobin (Hb), as well as blood gas indicators such as arterial blood pH, oxygen supply (DO2) and oxygen consumption (VO2).

[0004] As such, medical professionals must record patient biometric information thoroughly while communicating with each other to ensure smooth surgery. This places a heavy burden on medical professionals during surgery. Furthermore, for example, the patient's biometric information recorded by anesthesiologists and clinical engineers may overlap. It is also difficult for doctors to perform medical procedures while comprehensively examining multiple patient biometric information. Furthermore, while there is a common policy of performing a blood transfusion when hematocrit and hemoglobin levels drop, the hematocrit and hemoglobin thresholds for determining whether to perform a transfusion may vary depending on the facility, the attending physician, etc. Therefore, there is a need to reduce the burden on medical professionals, such as doctors, clinical engineers, anesthesiologists, and nurses, and prevent them from forgetting to record patient biometric information. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] US Patent Application Publication No. 2019 / 0034591 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a biometric information storage system and a biometric information storage program that can reduce the burden on medical professionals such as doctors, clinical engineers, anesthesiologists, and nurses, and prevent them from forgetting to record patients' biometric information. [Means for solving the problem]

[0007] the display unit displays the biometric information; a display processing unit that executes a process of displaying a plurality of surgical processes on the display unit and arranging a plurality of selected processes selected from the plurality of surgical processes as processes of the planned surgical procedure in the chronological order of the surgical procedure on the display unit; a storage processing unit that executes a process of, when the surgery starts, storing the biometric information measured by the measurement unit in the storage unit in correspondence with the chronological order for each of the selected processes whose chronological order is predetermined; a report generation processing unit that executes a process of generating a report based on the biometric information stored in the storage unit; and a risk prediction unit that predicts the risk of complications that may occur after the surgery is completed based on the biometric information stored in the storage unit and a trained model that is previously stored in the storage unit, and Rami A scheduled process that is the selection process to be carried out but designation And When this occurs, the problem is solved by a biometric information storage system characterized in that the risk prediction unit extracts and compares events that may occur in connection with the specified scheduled process based on the biometric information stored in the storage unit from a preset reference time point to the specified scheduled process, and predicts future event risks.

[0008] In the biometric information storage system according to the present invention, the display processing unit displays multiple surgical processes on the display unit. When a medical professional, such as a doctor, clinical engineer, anesthesiologist, or nurse, selects multiple selected processes from the multiple surgical processes displayed on the display unit as planned surgical processes, the display processing unit arranges the selected processes in chronological order of the surgical procedure and displays them on the display unit. When the surgery begins, the storage processing unit stores the biometric information measured by the measurement unit in the storage unit for each selected process. Because surgical procedures and procedures are relatively uniform, the storage processing unit can automatically store the patient's biometric information during the surgery in the storage unit in accordance with the flow of the surgery. Furthermore, whenever an additional procedure is added, the display processing unit executes a process of adding a freely input process to the chronologically arranged procedures. The storage processing unit then executes a process of storing the biometric information measured by the measurement unit in the storage unit. In this case, the timing at which the storage processing unit stores the biometric information in the storage unit may be automatic or may be determined by the medical professional. The report generation processing unit then generates a report based on the biometric information stored in the storage unit. Therefore, the report generation processing unit can avoid cumbersome recording work and automatically create reports with simple operations. As a result, the biometric information storage system according to the present invention can reduce the burden on medical professionals such as doctors, clinical engineers, anesthesiologists, and nurses, and can reduce the likelihood of them forgetting to record patient biometric information. Furthermore, in the biometric information storage system according to the present invention, the risk prediction unit predicts the risk of complications that may occur after the completion of surgery based on the biometric information stored in the storage unit for each selection process and the trained model pre-stored in the storage unit. As a result, the biometric information storage system according to the present invention can present the risk of complications that may occur after the completion of surgery to medical professionals, thereby reducing the burden on medical professionals and supporting their decision-making. Furthermore, in the biometric information storage system according to the present invention, after the start of surgery, the risk prediction unit further predicts future event risks that will occur if the scheduled process is performed, based on the biometric information stored in the storage unit. The scheduled process is a process designated from among the selected processes that are performed before the start of surgery as the surgery progresses. This allows the biometric information storage system according to the present invention to present future event risks that will occur if the scheduled process is performed in accordance with the flow of the selected process, thereby reducing the burden on medical personnel and supporting their decision-making. Furthermore, preferably, in the biometric information storage system, after the surgery has begun, when the display processing unit specifies a selection process that has already been performed from among the selection processes as the surgery progresses, the risk prediction unit extracts and compares events that may occur in connection with the specified selection process that has already been performed, based on the biometric information stored in the storage unit between a predetermined reference point and the specified selection process, and predicts future event risks.

[0009] In the biometric information storage system of the present invention, the display processing unit is preferably characterized in that it adds the selection processes that are subsequently selected or input to the plurality of selection processes that have been once selected, and rearranges the plurality of selection processes that have been once selected and the selection processes that are subsequently selected or input in chronological order of the surgical procedures and displays them on the display unit.

[0010] According to the biometric information storage system of the present invention, even if a medical professional has once selected multiple selected processes, if the medical professional later adds a selected process, the display processing unit rearranges the multiple selected selected processes and the subsequently selected or input selected process in chronological order of the surgical procedure and displays them on the display unit. This allows the biometric information storage system of the present invention to flexibly accommodate various surgical procedures.

[0011] In the biometric information storage system of the present invention, it is preferable that the display processing unit executes a process to display, on the display unit, the biometric information in a designated process specified from among the selected processes that have ended as the surgery progresses, after the surgery has begun.

[0012] According to the biometric information storage system of the present invention, after the start of surgery, the display processing unit displays on the display unit the biometric information in a designated process designated from among the selected processes that have been completed as the surgery progresses, thereby allowing medical personnel to easily check the biometric information in the designated process designated from among the selected processes that have been completed on the display unit in a shorter time.

[0013] In the biometric information storage system according to the present invention, the plurality of selection processes preferably includes a predetermined course of surgery.

[0014] According to the biometric information storage system of the present invention, the multiple selected processes include predetermined surgical courses. This allows medical personnel to easily select almost the entire planned surgical course, eliminating the need to individually select the planned surgical course. Furthermore, the surgical course can be customized and registered according to differences between facilities and doctors.

[0015] The biological information storage system according to the present invention preferably further comprises an input processing unit that executes a process of inputting information about the patient before the start of the surgery.

[0016] In the biometric information storage system according to the present invention, the input processing unit inputs information about the patient before the start of surgery (patient background, preoperative test data, etc.), which allows medical personnel to easily check on the display unit information that combines the information about the patient before the start of surgery and the biometric information stored in the storage unit for each selected process.

[0019] In the biometric information storage system of the present invention, the complications preferably include at least one of acute kidney injury, acute respiratory distress syndrome, cerebral infarction, non-occlusive intestinal ischemia, postoperative hypotension, and infection.

[0020] The biometric information storage system of the present invention presents medical professionals with the risk of complications that may occur after surgery, including at least one of acute kidney injury, acute respiratory distress syndrome, cerebral infarction, non-occlusive intestinal ischemia, postoperative hypotension, and infection, thereby reducing the burden on medical professionals and supporting their decision-making.

[0023] In the biometric information storage system of the present invention, the risk prediction unit is preferably further characterized in that it predicts, based on the biometric information stored in the storage unit, the future event risk that will occur if an unplanned process different from the selected process is performed after the surgery has begun.

[0024] According to the biometric information storage system of the present invention, the risk prediction unit further predicts future event risks that may occur if an unplanned process is performed after surgery has begun, based on the biometric information stored in the storage unit. The unplanned process is a process that is different from the selected process selected as a process for the scheduled surgery. In other words, the unplanned process is an additional medical procedure or process that is required. In this way, the biometric information storage system of the present invention presents future event risks that may occur if an unplanned process that was not planned to be performed in accordance with the flow of the selected process is performed, thereby reducing the burden on medical professionals and supporting their decision-making.

[0025] The biometric information storage system of the present invention is preferably characterized by further comprising an alert processing unit that executes a process of issuing an alert when the probability of the risk predicted by the risk prediction unit is equal to or greater than a threshold value.

[0026] In the biometric information storage system according to the present invention, the notification processor issues an alert when the probability of the risk predicted by the risk predictor is equal to or greater than a threshold, thereby enabling medical personnel to easily recognize the high risk of complications occurring after surgery, the high risk of future events occurring when a scheduled process is performed, or the high risk of future events occurring when an unplanned process is performed.

[0027] The problem is to provide a biometric information storage program executed by a computer of a biometric information storage system including a measurement unit that measures biometric information of a patient undergoing surgery, a memory unit that stores the biometric information measured by the measurement unit, a display unit that displays the biometric information, and a risk prediction unit that predicts the risk of complications that will occur after completion of the surgery based on the biometric information stored in the memory unit and a trained model that has been pre-stored in the memory unit, the biometric information storage program causing the computer to execute the following steps: a first step of displaying a plurality of surgical processes on the display unit; a second step of displaying a plurality of selected processes selected from the plurality of surgical processes as processes of the planned surgery in chronological order of the surgical procedures on the display unit; a third step of storing, when the surgery starts, the biometric information measured by the measurement unit for each selected process in a predetermined chronological order in the memory unit in accordance with the chronological order; and a fourth step of generating a report based on the biometric information stored in the memory unit; and, after the surgery has started, a risk prediction unit that predicts the risk of complications that will occur after completion of the surgery based on the biometric information stored in the memory unit. Rami A scheduled process that is the selection process to be carried out but designation And When the risk prediction unit detects a future event risk, the risk prediction unit extracts and compares events that may occur in connection with the designated scheduled process based on the biometric information stored in the storage unit from a predetermined reference time point to the designated scheduled process.

[0028] According to the biometric information storage program of the present invention, in a first step, multiple surgical processes are displayed on a display unit. Then, when a medical professional, such as a doctor, clinical engineer, anesthesiologist, or nurse, selects multiple selected processes from the multiple surgical processes displayed on the display unit as the planned surgical process, in a second step, the selected multiple selected processes are displayed on the display unit in chronological order of the surgical procedure. In addition, in a third step, when the surgery begins, biometric information measured by a measurement unit is stored in a memory unit for each selected process. Because surgical procedures and procedures are relatively uniform, in the third step, the patient's biometric information during the surgery is automatically stored in the memory unit along the flow of the surgery. Furthermore, whenever an additional procedure is added, the process freely input in the second step is added to the chronologically arranged procedures. In the third step, the biometric information measured by the measurement unit at that time is stored. In this case, the timing of storing the biometric information in the memory unit in the third step may be automatic or may be determined by a medical professional. In a fourth step, a report is generated based on the biometric information stored in the memory unit. Therefore, the fourth step makes it possible to avoid cumbersome recording work and automatically create a report with simple operations. As a result, the biometric information storage program according to the present invention can reduce the burden on medical professionals such as surgeons, anesthesiologists, and clinical engineers. [Effects of the Invention]

[0029] According to the present invention, it is possible to provide a biometric information storage system and a biometric information storage program that can reduce the burden on medical professionals such as doctors, clinical engineers, anesthesiologists, and nurses and prevent them from forgetting to record patients' biometric information.

[0031] Preferred embodiments of the present invention will now be described in detail with reference to the drawings. The embodiments described below are preferred examples of the present invention, and therefore various technically preferable limitations are applied thereto, but the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is particularly limited. Furthermore, in each drawing, similar components are designated by the same reference numerals, and detailed descriptions thereof will be omitted as appropriate.

[0032] FIG. 1 is a block diagram showing the configuration of the main part of a biological information storage system according to an embodiment of the present invention. The biological information storage system 2 according to this embodiment includes a control system 3 and a measurement unit 41. As shown in Fig. 1, the biological information storage system 2 may include an external monitor 42. The external monitor 42 is provided separately from the control system 3 and is an example of the "display unit" of the present invention.

[0033] The control system 3 acquires various information and performs calculations, and also generates control signals to control the operation of devices such as the external monitor 42 and transmits them to each device. In other words, the control system 3 manages the biometric information storage system 2. Details of the control system 3 will be described later. The control system 3 may also have a touch panel 33 as an input unit that can input various information and as a display unit that displays various information. In other words, the "display unit" of the present invention may be the external monitor 42 provided separately from the control system 3, or may be the touch panel 33 included in the control system 3. The touch panel 33 is configured to be able to detect touches such as those of the finger of an operator such as a medical professional. In the following description, a case where the "display unit" of the present invention is the touch panel 33 will be exemplified.

[0034] The measurement unit 41 measures the biological information of a patient undergoing surgery. Examples of the biological information measured by the measurement unit 41 include heart rate, pulse rate, respiratory rate, blood pressure, and body temperature. Examples of the biological information measured by the measurement unit 41 include blood test indices such as lactate, hematocrit (Ht), and hemoglobin (Hb), as well as blood gas indices such as mixed venous oxygen saturation (SvO2), mixed venous oxygen content (CvO2), carbon dioxide production (VCO2), oxygen supply (DO2), and oxygen consumption (VO2). When an extracorporeal circulation device is used in surgery, examples of the biological information measured by the measurement unit 41 include circulatory perfusion volume and cardiac output. However, the biological information measured by the measurement unit 41 is not limited to these. The biological information is also referred to as a parameter.

[0035] The "extracorporeal circulation" performed by the extracorporeal circulation device includes an "extracorporeal circulation operation" and an "auxiliary circulation operation." The extracorporeal circulation device can perform both the "extracorporeal circulation operation" and the "auxiliary circulation operation."

[0036] "Extracorporeal circulation" refers to the circulation of blood and gas exchange (oxygen addition and / or carbon dioxide removal) of blood performed by an extracorporeal circulation device when, for example, cardiac surgery temporarily stops blood circulation in the heart. In addition, "auxiliary circulation operation" refers to the blood circulation operation and gas exchange operation for the blood being performed by the extracorporeal circulation device when the heart of the patient to whom the extracorporeal circulation device is applied is unable to function properly or when gas exchange by the lungs is unable to be performed sufficiently.

[0037] For example, extracorporeal circulation systems are used when a patient's heart is not functioning normally, or when the patient's heart is functioning normally but the lungs are not. Extracorporeal circulation systems are used, for example, during cardiac surgery and subsequent treatment in an ICU. The extracorporeal circulation system operates a pump to draw blood from the patient's veins, oxygenates the blood by performing gas exchange in the blood using an artificial lung, and then returns the oxygenated blood to the patient's arteries or veins, performing an artificial pulmonary extracorporeal blood circulation. In this way, the extracorporeal circulation system acts as a substitute for the heart and lungs.

[0038] As described above, the measurement unit 41 measures various biological information of the patient undergoing surgery. Therefore, the measurement unit 41 is not limited to a single measuring device, and may include multiple measuring devices. The measurement unit 41 measures the biological information of the patient undergoing surgery and transmits a signal related to the biological information to the control system 3.

[0039] The control system 3 has a control unit 31, a storage unit 32, a touch panel 33, and a communication unit 34. The control unit 31 is included in a computer, and reads out a program 323 stored in the storage unit 32 to execute various calculations and processes. The "computer" here is not limited to a personal computer, but also includes an arithmetic processing unit, a microcomputer, etc. included in information processing equipment, and is a general term for equipment or devices that can realize the functions of the present invention by a program. The program 323 of this embodiment is an example of the "biometric information storage program" of the present invention.

[0040] The control unit 31 has a display processing unit 311, a storage processing unit 312, a report generation processing unit 313, an input processing unit 314, a risk prediction unit 315, and a notification processing unit 316. The display processing unit 311, the storage processing unit 312, the report generation processing unit 313, the input processing unit 314, the risk prediction unit 315, and the notification processing unit 316 are realized by the control unit 31 executing a program 323 stored (memorized) in the memory unit 32. Note that the display processing unit 311, the storage processing unit 312, the report generation processing unit 313, the input processing unit 314, the risk prediction unit 315, and the notification processing unit 316 may be realized by hardware or a combination of hardware and software.

[0041] The display processing unit 311 executes processing to display at least one of the surgical process and the biological information 321 measured by the measurement unit 41 and stored in the memory unit 32 on the touch panel 33. The display processing unit 311 may also execute processing to display at least one of the surgical process and the biological information 321 on the external monitor 42. Here, in this specification, the term "process" refers to at least one of medical acts, procedures, and events performed during surgery by medical professionals such as doctors, clinical engineers, anesthesiologists, and nurses.

[0042] The storage processing unit 312 executes a process of storing the biological information 321 measured by the measurement unit 41 and received by the communication unit 34 in the storage unit 32. As will be described later, when a surgery starts, the storage processing unit 312 executes a process of storing the biological information 321 measured by the measurement unit 41 in the storage unit 32 for each process. The storage processing unit 312 also executes a process of storing in the storage unit 32 at least one of the date and time when the surgery was performed, the date and time when the surgical process was performed, and the date and time when the measurement unit 41 measured the biological information 321.

[0043] The report generation processing unit 313 executes processing to generate a report based on the biological information 321 stored in the storage unit 32. Examples of reports generated by the report generation processing unit 313 include a report in which the surgical process is arranged in chronological order from top to bottom or left to right, and the biological information 321 stored in the storage unit 32 is displayed or written for each process. However, the reports generated by the report generation processing unit 313 are not limited to this.

[0044] The input processing unit 314 executes a process of inputting information input by a medical professional who has been granted access to the biometric information storage system 2 (hereinafter, a medical professional refers to a medical professional who has been granted access to the biometric information storage system 2) in response to the medical professional's operation on an input unit such as the touch panel 33. For example, the input processing unit 314 executes a process of inputting information about a patient before the start of surgery and a process of storing the information in the memory unit 32. Note that the input processing unit 314 may execute a process of inputting information about a patient, and the memory processing unit 312 may execute a process of storing the information about the patient input and processed by the input processing unit 314 in the memory unit 32. Alternatively, for example, the input processing unit 314 executes a process of inputting information about a patient before the start of surgery and a process of displaying the information on the touch panel 33. Note that the input processing unit 314 may execute a process of inputting information about a patient, and the display processing unit 311 may execute a process of displaying the information about the patient input and processed by the input processing unit 314 on the touch panel 33.

[0045] The risk prediction unit 315 predicts the risk of complications that may occur after the completion of surgery. In this specification, the term "complication" includes at least one of acute kidney injury, acute respiratory distress syndrome, cerebral infarction, non-occlusive intestinal ischemia, postoperative hypotension, and infection. For example, the risk prediction unit 315 predicts the risk of complications that may occur after the completion of surgery based on the biological information 321 stored in the storage unit 32 and a trained model 322 pre-stored in the storage unit 32. Alternatively, for example, the risk prediction unit 315 predicts the risk of future events that may occur if a scheduled surgical procedure is performed based on the biological information 321 stored in the storage unit 32. Alternatively, for example, the risk prediction unit 315 predicts the risk of future events that may occur if a procedure different from the scheduled surgical procedure is performed based on the biological information 321 stored in the storage unit 32.

[0046] The notification processing unit 316 executes a process of issuing an alert when a predetermined condition is satisfied. For example, when the probability of a complication risk predicted by the risk prediction unit 315 is equal to or greater than a threshold, the notification processing unit 316 issues an alert on the touch panel 33 and the external monitor 42. The notification by the notification processing unit 316 may be performed by, for example, emitting light or sound.

[0047] The storage unit 32 stores (memorizes) a program 323 executed by a computer including the control unit 31. The program 323 includes a sequence program for measurement, an image processing program for image processing, an arithmetic program, etc. The storage unit 32 may be, for example, a semiconductor memory built into the control system 3. Alternatively, the storage unit 32 may be various storage media or data servers connectable to the control system 3, such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk, or a memory card. Note that the program 323 is not limited to being stored in the storage unit 32; it may be pre-stored in a computer-readable storage medium and distributed, or may be downloaded to the control system 3 via a network.

[0048] The memory unit 32 also stores biometric information 321 measured by the measurement unit 41 and received by the communication unit 34. For example, the memory unit 32 stores the biometric information 321 measured by the measurement unit 41 for each surgical process, i.e., in association with the surgical process. The memory unit 32 further stores a trained model 322. The trained model 322 is a model trained by the control unit 31 using a prediction algorithm created based on data consisting of a combination of information about the patient, including the biometric information 321, and past complications that occurred after the end of surgery.

[0049] Next, the operation of the biological information storage system according to this embodiment, that is, the processing executed by the biological information storage system according to this embodiment, will be described with reference to the drawings. 2 to 4 are schematic diagrams showing examples of images displayed on the touch panel of this embodiment. As mentioned above, in the description of this embodiment, the "display unit" of the present invention is exemplified as the touch panel 33. However, the "display unit" of the present invention may also be the external monitor 42. That is, the example images shown in FIGS. 2 to 4 may be displayed on the external monitor 42.

[0050] As shown in FIG. 2, when the operation of the biological information storage system 2 according to this embodiment starts, the display processing unit 311 displays a surgery process group 5, a complication risk group 6, and pre-surgery information 7.

[0051] The surgical process group 5 includes multiple scheduled surgical processes 51. In the example image shown in FIG. 2, multiple surgical processes 51, such as "ON CPB (cardiopulmonary bypass ON)," "OFF CPB (cardiopulmonary bypass OFF)," "AO X CLAMP," "X Clamp OFF," "LOWER temp," "Rewarm," "Collect graft," "CABG 1X," "Heparin 1 Unit," and "Dialysis," are displayed on the touch panel 33. The displayed processes are not limited to these, and the arrangement of the processes may be changed by the user, or some may be organized into sets. For example, if a mitral valve replacement is to be performed, selecting the set "mitral valve replacement" selects general processes at once, and the process may be reselected depending on the case of the day. The process set may also be optimized by the attending physician or facility.

[0052] The complication risk group 6 includes multiple complication risks 61. In the example image shown in FIG. 2, multiple complication risks 61 such as "AKI," "Severe AKI," "Neuro," "Infection," "Bleed," and "Resp.impair" are displayed on the touch panel 33. The notation method may be any that is easy to understand, and although acute kidney injury is represented as AKI and bleeding as Bleed here, it is not limited to this.

[0053] The pre-operative information 7 includes information about the patient before the start of surgery (patient background, pre-operative test data, etc.). In the example image shown in FIG. 2, the "Sex" and "Age" of the patient undergoing surgery are displayed on the touch panel 33. For example, the pre-operative information 7 is information input by a medical professional in response to the medical professional's operation on an input unit such as the touch panel 33, and is information that has been input and processed by the input processing unit 314.

[0054] Next, as shown in Fig. 3, when a medical professional such as a doctor, clinical engineer, anesthesiologist, or nurse selects multiple processes from among multiple surgery processes 51 (see Fig. 2) displayed on the touch panel 33 as the process of the scheduled surgery, the display processing unit 311 arranges the selected multiple processes in chronological order of the surgery procedures and displays them on the touch panel 33. In this embodiment, for convenience of explanation, a process selected by a medical professional from among multiple surgery processes 51 displayed on the touch panel 33 is referred to as a "selected process." The selected process 52 (see Fig. 3) is selected by the medical professional, for example, in response to the medical professional's operation on an input unit such as the touch panel 33.

[0055] In the example image shown in FIG. 3, as indicated by arrow A1, multiple selection processes 52, namely, "ON CPB," "AO X CLAMP," "LOWERtemp," "Rewarm," "X Clamp OFF," and "OFF CPB," are displayed on touch panel 33 in this order from left to right in chronological order of the surgical procedure.

[0056] The multiple selection processes 52 selected by the medical professional may include a predetermined surgical course. A surgical course is a framework in which at least one of multiple medical procedures, procedures, and events scheduled for surgery are arranged in chronological order. For example, if the planned surgery is a "CABG-1 branch," the medical professional can select "CABG 1X" (see Figure 2) displayed on the touch panel 33. At least one of multiple medical procedures, procedures, and events predefined for the "CABG-1 branch" surgical course is automatically arranged in chronological order of the "CABG-1 branch" surgical procedure and displayed on the touch panel 33. This eliminates the need for the medical professional to individually select the planned surgical process, allowing the medical professional to easily select the entire planned surgical process. Furthermore, the surgical process can be customized and registered depending on the facility or physician. The process selected when the planned surgery is a "CABG-1 branch" is not limited to "CABG 1X."

[0057] 3, the display processing unit 311 can add a later selected or input selection process 52 to a state in which a plurality of selection processes 52 are arranged in chronological order of the surgical procedure and displayed on the touch panel 33, and display the later selected or input selection process 52 on the touch panel 33. That is, the display processing unit 311 can execute a process of adding a later selected or input selection process 52 to a plurality of once selected selection processes 52 (see FIG. 3), and rearranging the once selected plurality of selection processes 52 and the later selected or input selection process 52 in chronological order of the surgical procedure and displaying them on the touch panel 33. This allows the biological information storage system 2 according to this embodiment to flexibly accommodate various surgical processes.

[0058] Next, when the surgery begins, the storage processing unit 312 stores the biological information 321 measured by the measurement unit 41 in the storage unit 32 for each selected process 52. Because surgical procedures and procedures are fairly uniform, the storage processing unit 312 can automatically store the patient's biological information 321 during the surgery in the storage unit 32 in accordance with the flow of the surgery. Furthermore, when an additional procedure is performed, the display processing unit 311 executes processing to add the freely input process to the chronologically arranged procedures. The storage processing unit 312 then executes processing to store the biological information 321 measured by the measurement unit 41 in the storage unit 32. In this case, the timing at which the storage processing unit 312 stores the biological information 321 in the storage unit 32 may be automatic or may be the timing specified by a medical professional for the selection process 52. The storage processing unit 312 also executes processing to store in the storage unit 32 at least one of the date and time when the selection process 52 was performed and the date and time when the measurement unit 41 measured the biological information 321 in the selection process 52.

[0059] 4, after the surgery has started, when the medical professional designates an arbitrary process from among the selected processes 52 that have been completed as the surgery progresses, the display processing unit 311 reads the biometric information 321 of the process designated by the medical professional from the storage unit 32 and displays it on the touch panel 33. In this embodiment, for the sake of convenience, the process designated by the medical professional from among the selected processes 52 that have been completed as the surgery progresses is referred to as a "designated process." The designated process 53 (see FIG. 4) is designated by the medical professional in response to, for example, the medical professional's operation on an input unit such as the touch panel 33.

[0060] 4, multiple designated processes 53, including "ON CPB," "AO X CLAMP," "LOWERtemp," and "Rewarm," are designated by the medical professional and are highlighted. Then, the display processing unit 311 reads out from the storage unit 32 the biometric information 321 corresponding to each of the multiple designated processes 53 and stored in the storage unit 32 for each selected process 52, and displays it on the touch panel 33. This allows the medical professional to easily check the biometric information 321 for the designated process 53 designated from the selected processes 52 on the touch panel 33 in a short amount of time.

[0061] As described above, the pre-operative information 7 is displayed on the touch panel 33. This allows the medical staff to easily check on the touch panel 33 information that combines information about the patient before the start of surgery (i.e., the pre-operative information 7) and the biological information 321 stored in the storage unit 32 for each selection process 52, as shown in Fig. 4 .

[0062] Next, the risk prediction unit 315 predicts a complication risk 61 that will occur after the surgery based on the biological information 321 stored in the storage unit 32 for each selection process 52 and the trained model 322 pre-stored in the storage unit 32. Then, the notification processing unit 316 issues an alert when the probability of the risk predicted by the risk prediction unit 315 is equal to or greater than a threshold. In the example image shown in FIG. 4, among the multiple complication risks 61, "AKI" and "Neuro" are highlighted and alerted. In this case, the biological information 321 requiring attention may be highlighted.

[0063] As a result, the biological information storage system 2 according to this embodiment can present the risk of complications 61 that may occur after the end of surgery to medical personnel, thereby reducing the burden on medical personnel and supporting their judgment. In addition, medical personnel can easily recognize that the risk of complications 61 that may occur after the end of surgery is high.

[0064] Next, the report generation processing unit 313 generates a report based on the biological information 321 stored in the storage unit 32. For example, the report generation processing unit 313 generates a report in which the selection processes 52 are arranged in chronological order from top to bottom or from left to right, and the biological information 321 stored in the storage unit 32 is displayed or written for each selection process 52. The contents and items written in the report may be customizable for each facility or by the attending physician or medical professional.

[0065] As described above, in the biometric information storage system 2 and biometric information storage program according to this embodiment, the display processing unit 311 displays multiple surgical processes 51 on the touch panel 33. When a medical professional, such as a doctor, clinical engineer, anesthesiologist, or nurse, selects multiple selected processes 52 from the multiple surgical processes 51 displayed on the touch panel 33 as the process of a scheduled surgical procedure, the display processing unit 311 arranges the selected multiple selected processes 52 in chronological order of the surgical procedure and displays them on the touch panel 33. When the surgery begins, the storage processing unit 312 stores the biometric information 321 measured by the measurement unit 41 for each selected process 52 in the storage unit 32. Because surgical procedures and procedures are fairly uniform, the storage processing unit 312 can automatically store the patient's biometric information 321 during the surgery in the storage unit 32 in accordance with the flow of the surgery. Furthermore, whenever an additional procedure is performed, the display processing unit 311 executes a process of adding the freely input process to the chronologically arranged procedures. The storage processing unit 312 then executes a process of storing the biological information 321 measured by the measurement unit 41 in the storage unit 32. In this case, the timing at which the storage processing unit 312 stores the biological information 321 in the storage unit 32 may be automatic or may be the timing designated by a medical professional using the selection process 52. The report generation processing unit 313 then generates a report based on the biological information 321 stored in the storage unit 32. Therefore, the report generation processing unit 313 can avoid cumbersome recording work and automatically create a report with simple operations. As a result, the biological information storage system 2 according to this embodiment can reduce the burden on medical professionals such as doctors, clinical engineers, anesthesiologists, and nurses and reduce the likelihood of forgetting to record the patient's biological information 321.

[0066] Next, the operation of the biometric information storage system according to this embodiment, that is, a specific example of the processing executed by the biometric information storage system according to this embodiment, will be described with reference to the drawings. FIG. 5 is a flowchart illustrating a specific example of the operation of the biological information storage system according to this embodiment.

[0067] First, in step S11, a medical professional starts the operation of the biometric information storage system 2. Then, in step S12, the display processing unit 311 displays a plurality of surgical processes 51 (see FIG. 2) on the display unit (touch panel 33 in this embodiment). Step S12 in this embodiment is an example of the "first step" of the present invention. Next, in step S13, the display processing unit 311 displays a plurality of selected processes 52 selected from the plurality of surgical processes 51 displayed on the touch panel 33 as the process of the scheduled surgical operation, in chronological order of the surgical procedure, on the touch panel 33 (see FIG. 3). Step S13 in this embodiment is an example of the "second step" of the present invention.

[0068] Next, in step S14, if there is an additional procedure, the display processing unit 311 executes processing to add the freely input process to the procedure arranged in chronological order. That is, if there is a selected process 52 selected or input later to multiple selected processes 52 that have already been selected, the display processing unit 311 adds the later selected or input selected process 52. Then, the display processing unit 311 executes processing to rearrange the multiple selected processes 52 that have already been selected and the later selected or input selected process 52 in chronological order of the surgical procedure, and display them on the touch panel 33.

[0069] Next, in step S15, the control unit 31 determines whether the surgery schedule (i.e., the selection processes 52) are arranged in chronological order. If the surgery schedule (i.e., the selection processes 52) are not arranged in chronological order (step S15: NO), in step S16, the display processing unit 311 executes a process to add the necessary selection processes 52 added by the medical staff. On the other hand, if the surgery schedule (i.e., the selection processes 52) are arranged in chronological order (step S15: YES), in step S17, the storage processing unit 312 stores the biological information 321 measured by the measurement unit 41 for each selection process 52 in the storage unit 32 when the surgery starts. Step S17 in this embodiment is an example of the "third step" of the present invention.

[0070] Next, in step S18, at the timing when the medical worker desires to display parameters (i.e., biological information 321), he / she touches a pre-arranged selected process 52 on the touch panel 33. Then, in step S19, the display processing unit 311 displays pre-set parameters (vital signs, measurement values, test values, conditions, etc.) on the touch panel 33 simultaneously with the selected process 52 touched by the medical worker. That is, in step S19, the display processing unit 311 reads parameters including biological information 321 for the specified process 53 (see FIG. 4 ) specified by the medical worker from the storage unit 32 and displays them on the touch panel 33.

[0071] At this time, the display processing unit 311 displays on the touch panel 33 the biological information 321 whose value has increased compared to the previous value and the biological information 321 whose value has decreased compared to the previous value so that the medical staff can easily recognize them. For example, the display processing unit 311 displays a color and an arrow next to the biological information 321, or changes the inclination of the arrow according to the rate of change, thereby displaying the status of the change in the biological information 321 on the touch panel 33. Furthermore, if there are items that need to be additionally displayed, the display processing unit 311 may additionally display the necessary items on the touch panel 33.

[0072] Subsequently, in step S21, the report generation processing unit 313 generates a report based on the biological information 321 stored in the storage unit 32. Step S21 of the present embodiment is an example of the "fourth step" of the present invention.

[0073] Next, in step S22, the risk prediction unit 315 predicts a complication risk 61 that will occur after the end of the surgery, based on the biological information 321 stored in the storage unit 32 for each selection process 52 and the trained model 322 pre-stored in the storage unit 32. Next, in step S23, the notification processing unit 316 determines whether the probability of the risk predicted by the risk prediction unit 315 is equal to or greater than a threshold. If the probability of the risk predicted by the risk prediction unit 315 is equal to or greater than a threshold (step S23: YES), in step S24, the notification processing unit 316 displays an alert on the touch panel 33. On the other hand, if the probability of the risk predicted by the risk prediction unit 315 is not equal to or greater than the threshold (step S23: NO), the notification processing unit 316 does not display an alert on the touch panel 33.

[0074] Subsequently, in step S25, the display processing unit 311 displays the results of the risk predicted by the risk prediction unit 315 on the touch panel 33. Furthermore, in step S26, the display processing unit 311 highlights parameters that require attention.

[0075] Next, a specific example of the process executed by the risk prediction unit 315 of this embodiment will be described with reference to the drawings. FIG. 6 is a flowchart illustrating a first specific example of the processing executed by the risk prediction unit of this embodiment.

[0076] In this specific example, the risk prediction unit 315 predicts future event risks that will occur if, after the start of surgery, a process designated from among the pre-start selected processes 52 (see FIG. 4 ) is performed as the surgery progresses, based on the biological information 321 stored in the storage unit 32. In this embodiment, for ease of explanation, a process designated by a medical professional from among the pre-start selected processes 52 as the surgery progresses is referred to as a "scheduled process." The scheduled process 54 (see FIG. 4 ) is designated by the medical professional, for example, in response to the medical professional's operation on an input unit such as the touch panel 33.

[0077] 4, the current time point among the multiple selection processes 52 during surgery is represented by a triangle mark 58. In the example image shown in FIG. 4, the selection processes 52 before starting as the surgery progresses are "X Clamp OFF" and "OFF CPB." When a medical professional specifies at least one of "X Clamp OFF" and "OFF CPB" as a scheduled process 54, the risk prediction unit 315 predicts the future event risk that will occur if the scheduled process 54 is performed, based on the biological information 321 stored in the memory unit 32.

[0078] That is, in step S31, after the start of surgery, the medical professional specifies a scheduled process 54 from among the previously selected processes 52 that have not yet started as the surgery progresses. A "scheduled process" is also called a "scheduled procedure" or a "scheduled event." Next, in step S32, the display processing unit 311 sets the scheduled process 54 on an expected timeline (i.e., processes arranged in chronological order) and displays it on the touch panel 33.

[0079] Next, in step S33, the risk prediction unit 315 extracts and compares events that may occur in association with the specified scheduled process 54 based on the biological information 321 stored in the storage unit 32 from a preset baseline (i.e., data at a reference time point) to that time point. Next, in step S34, the risk prediction unit 315 determines whether any risk will change, i.e., whether an event risk will occur in the future.

[0080] If any risk remains unchanged (step S34: NO), in step S35, the display processing unit 311 displays the possibility that the risk will remain unchanged on the touch panel 33. On the other hand, if any risk changes (step S34: YES), in step S36, the display processing unit 311 highlights the portion of the risk that has changed.

[0081] According to this specific example, the biometric information storage system 2 presents the future event risks that will occur if the scheduled process 54 is carried out in accordance with the flow of the selection process 52, thereby reducing the burden on medical professionals and supporting their judgment.

[0082] FIG. 7 is a flowchart illustrating a second specific example of the processing executed by the risk prediction unit of this embodiment. In this specific example, the risk prediction unit 315 predicts future event risks that will occur when a process designated from among the selection processes 52 performed as the surgery progresses after the start of the surgery is performed, based on the biological information 321 stored in the storage unit 32. In this embodiment, for ease of explanation, a process designated by a medical professional from among the selection processes 52 performed as the surgery progresses is referred to as a "performed process." A "performed process" is also referred to as a "performed procedure" or a "performed event."

[0083] To explain this using the example image shown in Figure 4, the selected process 52 performed as the surgery progresses is displayed to the left of the triangle mark 58 shown in Figure 4. Furthermore, the performed process designated from among the selected processes 52 performed as the surgery progresses corresponds to the designated process 53 described above with reference to Figure 4. As described above with reference to Figure 4, the designated process 53 is designated by the medical professional in response to the medical professional's operation on an input unit such as the touch panel 33, for example.

[0084] First, in step S41, after the start of surgery, the medical staff designates a completed process from among the selected processes 52 that have been performed as the surgery progresses. Next, in step S42, the display processing unit 311 sets the completed process on a timeline of the performed processes (i.e., the processes arranged in chronological order) and displays it on the touch panel 33.

[0085] Next, in step S43, the risk prediction unit 315 extracts and compares events that may occur in association with the specified performed process based on the biological information 321 stored in the storage unit 32 from a preset baseline (i.e., data at a reference time point) to that time point. Next, in step S44, the risk prediction unit 315 determines whether any risk will change, i.e., whether an event risk will occur in the future.

[0086] If any risk remains unchanged (step S44: NO), in step S45, the display processing unit 311 displays the possibility that the risk will remain unchanged on the touch panel 33. On the other hand, if any risk changes (step S44: YES), in step S46, the display processing unit 311 highlights the portion of the risk that has changed.

[0087] According to this specific example, the biometric information storage system 2 presents future event risks that may occur after the processes that have been performed as the surgery progresses, thereby reducing the burden on medical personnel and supporting their decision-making.

[0088] FIG. 8 is a schematic diagram illustrating a third specific example of the processing executed by the risk prediction unit of this embodiment. FIG. 8 is a schematic diagram showing an example of an image displayed on the touch panel of this embodiment in this specific example.

[0089] In this specific example, the risk prediction unit 315 predicts future event risks that will occur if an unplanned process other than the selected process 52 is performed after the start of surgery, based on the biological information 321 stored in the storage unit 32. In this embodiment, for the sake of convenience, an unplanned process other than the selected process 52 selected by a medical professional as a process for the scheduled surgery is referred to as an "unplanned process." In other words, an unplanned process is an additional medical procedure or process that is required. In the example image shown in FIG. 8, "blood transfusion" is displayed as the unplanned process 55.

[0090] 8, the risk prediction unit 315 predicts a future event risk that will occur if a blood transfusion is performed as an unplanned process 55 after the start of surgery, based on the biological information 321 stored in the storage unit 32. Then, the display processing unit 311 highlights parameters that require attention based on the future event risk predicted by the risk prediction unit 315.

[0091] According to this specific example, the biometric information storage system 2 presents the future event risks that may occur if an unplanned process 55 that was not planned to be performed in accordance with the flow of the selection process 52 is performed, thereby reducing the burden on medical professionals and supporting their judgment.

[0092] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or arbitrarily combined in a different manner from the above. [Explanation of symbols]
