[0002] A medicine to be administered to a patient may be administered while controlling a flow rate or the like using a medical pump in some cases.

[0003] Patent Document 1 discloses a closed-loop fluid resuscitation and / or cardiovascular drug administration system using continuous measurement values and an adaptive control architecture, wherein the adaptive control architecture identifies unknown dynamics and physiological parameters of a patient using a function approximator to thereby calculate an appropriate infusion rate and adjust an endpoint of resuscitation.

[0005] A medical pump is used, for example, for administration of a medicine for appropriately maintaining a patient's blood pressure, blood glucose level, heart rate, or the like during an operation. For this reason, settings for a medical pump for controlling the flow rate, timing, and the like of a medicine to be administered are important settings related to the patient's life.

[0006] Such settings of a medical pump are often performed by a nurse who receives an instruction from a doctor. However, it is difficult for a doctor to grasp and instruct all setting items, and even for a nurse who has received an instruction, it has been difficult to determine by themselves whether or not the settings are within an allowable range for the patient.

[0007] In one aspect of the present disclosure, there is provided an information processing method or the like that allows a medical pump to be set more easily understandably and appropriately.

[0008] (1) An information processing method according to one aspect of the present disclosure receives medication information of a medicine to be administered to a patient and test value information of the patient that is affected by administration of the medicine, displays a flow rate control plan for a medical pump that defines conditions for changing a flow rate for administering the medicine according to the medication information based on a threshold of a test parameter included in the test value information, and accepts an input for changing a condition including the threshold on a screen on which the flow rate control plan is displayed, and also accepts an operation of approving operation according to the displayed flow rate control plan.

[0009] (2) In the information processing method described in (1) above, a time-series graph showing the temporal change in the patient's test parameter values ​​may also be displayed on the screen on which the flow rate control proposal is displayed.

[0010] (3) In the information processing method described in (2) above, the time-series graph may include a graph showing the time change of the patient's test values ​​included in the test value information, and information showing the timing of the change in flow rate and the changed flow rate, all aligned on a single time axis.

[0011] (4) In any of the information processing methods described in (1) to (3) above, the system may accept an operation to set the instantaneous value or moving average value of the inspection parameter as a condition relating to the threshold, and determine whether the condition is met according to the accepted setting.

[0012] (5) In any of the information processing methods described in (1) to (4) above, the method may accept an operation to set a continuous period of time for which the threshold is true, and determine whether the condition is met according to the accepted setting.

[0013] (6) In any of the information processing methods described in (1) to (5) above, the system may accept an operation to select whether to use either or both of the A-line blood pressure and cuff blood pressure values ​​as the blood pressure for the test parameter.

[0014] (7) In any of the information processing methods described in (1) to (6) above, the system may accept an operation to input the upper and lower limits of the flow rate of the medical pump, or the upper and lower limits of the inspection parameters related to the alert output.

[0015] (8) In any of the information processing methods described in (1) to (7) above, the proposed flow rate control for the medical pump may be displayed by a two-dimensional graph display using two types of the inspection parameters.

[0016] (9) In any of the information processing methods described in (1) to (8) above, the patient's physical information may be received, and based on the physical information, conditions may be set for changing the flow rate at which the drug is administered in the flow rate control plan.

[0017] (10) In any of the information processing methods described in (1) to (9) above, the medical pump may be instructed to operate based on the flow rate control proposal for which an approved operation has been received.

[0018] (11) An information processing device in one aspect of the present disclosure includes a control unit which receives drug administration information of a drug to be administered to a patient and the patient's test value information affected by the administration of the drug, and displays a flow rate control proposal for a medical pump which defines conditions for changing the flow rate of the drug to be administered based on the threshold of the test parameter included in the test value information, and on a screen which the flow rate control proposal is displayed, accepts input for changing the conditions including the threshold, and accepts an operation to approve operation with the displayed flow rate control proposal.

[0019] (12) A program in one aspect of the present disclosure is a program that receives drug administration information for a drug to be administered to a patient and laboratory value information of the patient affected by the administration of the drug, displays a flow rate control proposal for a medical pump that defines conditions for changing the flow rate of the drug to be administered based on threshold values ​​of laboratory parameters included in the laboratory value information, and causes a computer to execute a process on a screen where the flow rate control proposal is displayed, which accepts input for changing the conditions including the threshold values, and accepts an operation to approve operation with the displayed flow rate control proposal.

[0022] The information processing method, information processing apparatus, and program described herein will be described in detail below with reference to the drawings illustrating their embodiments. In the description, similar elements will be denoted by the same reference numerals, and redundant explanations will be omitted as appropriate.

[0023] Figure 1 is an explanatory diagram showing an example configuration of the drug administration system 1 of this disclosure. The drug administration system 1 of this embodiment includes an information processing device 2, a medical pump 3, and an inspection device 5.

[0024] The medical pump 3 controls the administration of the drug contained in the drug container 4 to patient P. The examination device 5 is a device for examining patient P's body and can be a device for examining necessary examination items for patient P's surgery or treatment. The information processing device 2 acquires information related to examination parameters (examination results related to patient P's body or information about drugs administered to the body) from the examination device 5 or the input unit 27 (see Figure 2) of the information processing device 2, displays suggestions for controlling the medical pump 3, and transmits information about the control performed by the medical pump 3 to the medical pump 3.

[0025] In this embodiment, the information acquired by the testing device 5 may include, for example, blood pressure, urine output, lactate level, body temperature, RASS (Richmond Agitation-Sedation Scale: assessment of sedation), potassium level, blood glucose level, cardiac output, drug concentration in the blood, blood oxygen concentration, APTT (Activated Partial Thromboplastin Time), etc. Here, blood pressure may be measured using a cuff sphygmomanometer, an A-line using a catheter, or both. Furthermore, in this embodiment, the information related to the test parameters acquired by the information processing device 2 may also include the dosage (flow rate or total dosage) administered by the medical pump 3 or the dosage (flow rate or total dosage) of drugs administered without the medical pump 3, etc.

[0026] In the following description, the laboratory parameters may include, for example, one or more of the following: blood pressure, urine output, lactate level, body temperature, RASS (Richmond Agitation-Sedation Scale: assessment of sedation), potassium level, blood glucose level, cardiac output, drug concentration in the blood, blood oxygen saturation, APTT (Activated Partial Thromboplastin Time), ACT (Activated Clotting Time), etc. Furthermore, the laboratory parameters may also include, one or more of the following: the amount (flow rate or total amount) administered by the medical pump 3 or the amount (flow rate or total amount) of the drug administered without the medical pump 3.

[0027] Furthermore, the test parameters are not limited to those acquired by the testing device 5, but also include test parameters directly input to the information processing device 2. For example, the test parameters may include test parameters input by the input unit 27 of the information processing device 2, such as urine volume, and flow rate or total dose received by the information processing device 2 from the medical pump 3.

[0028] Figure 2 is a block diagram showing an example configuration of an information processing device 2 relating to one aspect of this disclosure. The information processing device 2 is an information processing device that performs processing and storage of various types of information. The information processing device 2 may be configured as, for example, a server device, a personal computer, a tablet terminal, or a smartphone. The information processing device 2 may be composed of multiple information processing devices, or it may be configured as one of multiple virtual devices (virtual machines) configured within a single information processing device.

[0029] Here, the information processing device 2 can be an information processing device composed mainly of electronic circuits using semiconductor circuit elements. The information processing device 2 has a control unit 21, a communication unit 22, a reading unit 23, a storage unit 24, a display unit 26, and an input unit 27. The components of the control unit 21, communication unit 22, reading unit 23, storage unit 24, display unit 26, and input unit 27 are connected to each other so as to be able to communicate with one another by a bus 29 or the like.

[0030] The control unit 21 can be configured to have one or more processing units such as a CPU (Central Processing Unit), MPU (Micro-Processing Unit), GPU (Graphics Processing Unit), FPGA (Field Programmable Gate Array), DSP (Digital Signal Processor), and quantum processor. The control unit 21 reads and executes the program 241 stored in the storage unit 24.

[0031] The communication unit 22 is a communication module for performing communication-related processing and can send and receive information with the medical pump 3 or the inspection device 5. The communication unit 22 may also send and receive information via a communication network (not shown). The reading unit 23 can read portable storage media 25 such as CD (Compact Disc)-ROM (Read Only Memory), DVD (Digital Versatile Disc)-ROM, and USB (Universal Serial Bus) memory. The control unit 21 can read programs and / or data from the portable storage media 25 via the reading unit 23 and save them to the storage unit 24. The control unit 21 can also download programs 241 from other computers via a communication network (not shown) and save them to the storage unit 24. The information processing device 2 performs processing by executing programs 241.

[0032] The storage unit 24 includes volatile storage devices such as RAM (Random Access Memory), and non-volatile storage devices such as ROM, HDD (Hard Disk Drive), and flash memory. As shown in Figure 2, the storage unit 24 stores, for example, a program 241 and a patient database 242. The program 241 is a program executed by the control unit 21. The program 241 may also be referred to as a program product 241.

[0033] The display unit 26 can be a liquid crystal display or an organic EL (Electro-Luminescence) display, etc. The input unit 27 can be an input device such as a keyboard, mouse, touch panel, and camera.

[0034] Figure 3 shows an example of a patient database 242. As shown in Figure 3, the patient database 242 has a "physical information" group which has fields for "name," "gender," "age," "weight," "disease," and "blood pressure." It also has a "medication information" field which stores the drugs to be administered. Furthermore, the patient database 242 can store past flow control information, which has fields for "laboratory value information," "control laboratory parameters," "threshold," "change amount," "target control range," and "reference flow rate."

[0035] The "Name," "Gender," "Age," and "Weight" fields store the patient P's name, gender, age, and weight, respectively. The "Disease" field stores the name of the disease the patient P is being treated for, or the name of any pre-existing conditions the patient P has. The "Blood Pressure" field stores, for example, the patient P's most recent blood pressure (systolic / diastolic). Alternatively, the blood pressure may be stored as mean arterial pressure. Mean arterial pressure may be calculated using the following formula: Mean Arterial Pressure = Diastolic Blood Pressure + (Systolic Blood Pressure - Diastolic Blood Pressure) ÷ 3

[0036] The "Medication Information" field stores the names of the drugs to be administered using the medical pump 3 in the treatment to be performed on patient P. The "Laboratory Value Information" field, which serves as past flow rate control information, stores laboratory parameters acquired by the information processing device 2 in past medication administrations. The "Control Laboratory Parameters" field stores the names of the laboratory parameters used to determine whether to change the flow rate of the medical pump 3.

[0037] The "Threshold" field stores the value of the control test parameter that changes the flow rate of the fluid delivered by the medical pump 3. The information processing device 2 instructs the medical pump 3 to change the flow rate when the value of the control test parameter changes beyond the threshold. The "Change Amount" field stores the amount of change in flow rate when the value of the test parameter changes beyond the threshold. The "Target Control Range" field stores the range in which the value of the control test parameter should be maintained by flow rate control. The "Reference Flow Rate" field stores the flow rate of the drug to be administered when the value of the control test parameter is within the target control range.

[0038] The flow control information is not limited to the fields mentioned above, but can consist of any information necessary to create the flow control diagram described later. The fields in the patient database 242 may include other fields, or they may not include the fields included in Figure 3. In this embodiment, the patient P data is stored in a database, but it may also be in a text file or a tabular file.

[0039] Figure 4 is an overview front view of a medical pump 3 according to one embodiment of the present disclosure. In Figure 3, the X, Y, and Z directions are orthogonal to each other, and the Z direction is upward. In Figure 3, as an example, the medical pump 3 is shown as a syringe pump that administers a drug solution filled in a drug container 4 which is a syringe. However, the medical pump 3 used in the drug administration system 1 may be a medical pump 3 that dispenses drugs from another drug container 4 such as an infusion bag.

[0040] The medical pump 3 is used, for example, in an operating room or an intensive care unit such as an ICU (Intensive Care Unit), CCU (Coronary Care Unit), or NICU (Neonatal Intensive Care Unit) to continuously deliver drugs such as intravenous anesthetics or vasoactive drugs, which are filled in a drug container 4 such as a syringe 4, into the body of a patient P. The intravenous anesthetics include drugs that act on the nervous system to exert a sedative or analgesic effect.

[0041] The medical pump 3 can deliver various drugs, including intravenous anesthetics and vasoactive agents, which are filled in syringe 4, into the body of patient P. Examples of applicable intravenous anesthetics include propofol, midazolam, and remifentanil. Examples of applicable vasoactive agents include epinephrine, norepinephrine, dobutamine, dopamine, isosorbide dinitrate, and nitroglycerin.

[0042] As shown in FIG. 4, the medical pump 3 includes a cover 31. The cover 31 is integrally molded from a molded resin material having chemical resistance. Accordingly, the cover 31 has a splash-proof structure. Even if a medical agent or the like is splashed onto the medical pump 3, the splash-proof structure can suppress the ingress of the medical agent or the like into the interior of the medical pump 3. The cover 31 includes an upper cover portion 31A and a lower cover portion 31B.

[0043] An operation panel 32 is disposed on the upper cover portion 31A, and the operation panel 32 includes a display section 321 and an input section 322 for setting display or pump control. The display section 321 can be, for example, a display device such as a liquid crystal display device. The input section 322 is configured of buttons, a touch panel, and the like. The touch panel can be disposed overlapping a screen of the display section 321. The buttons may include a power ON / OFF button, a start button for starting drug delivery, a stop button for stopping drug delivery, a menu selection button, and the like. Note that operations received by the input section 322 can be received via communication by the information processing apparatus 2.

[0044] A syringe placement section 34 and a pusher driving section 33 for pushing a syringe pusher 43 are disposed on the lower cover portion 31B. The syringe placement section 34 includes an accommodation section 341 that accommodates a syringe body 41, and a clamp 342 that fixes the syringe body 41. To accommodate the syringe body 41, the accommodation section 341 is formed as a semi-cylindrical recess extending along the X direction. The syringe placement section 34 and the pusher driving section 33 are arranged side by side along the X direction. The syringe placement section 34 may have a structure for detachably fitting and fixing the syringe 4. The syringe placement section 34 can fix a plurality of types of syringes 4 having different sizes.

[0045] As shown in FIG. 4, the medical pump 3 presses, in the T direction, the syringe pusher 43 of the syringe 4 serving as the drug container 4 filled with a drug, which is placed in the syringe placement section 34, to deliver the drug in the syringe body 41 to a patient P via a tube 44 and an indwelling needle 45.

[0046] The syringe body 41 of the syringe 4 is arranged so as to be fixed to the medical pump 3 by the clamp 342. A user can attach and detach the syringe 4 by pulling the clamp 342 in the +Y direction (front direction) against the biasing force of a spring, rotating the clamp between an attachment position and a detachment position, and returning it (in the -Y direction). The syringe 4 is arranged in the housing portion 341 and fixed when the clamp 342 is placed at the attachment position. The clamp 342 is movable in the ±X directions so that the clamp 342 can fix the syringe 4 having various accommodation volumes such as 5 mL, 10 mL, 20 mL, 30 mL, and 50 mL.

[0047] When the syringe body 41 is housed and fixed in the housing portion 341, the syringe pusher 43 is arranged in the pusher driving portion 33. The pusher driving portion 33 includes a slider 331. When the motor 36 of the pusher driving portion 33 is driven according to a command from the control unit 351 (see Fig. 5), the motor 36 rotates the feed screw 332 to move the slider 331 in the T direction. Accordingly, the slider 331 pushes the pusher flange 431 of the syringe pusher 43 in the T direction, and delivers the medicine in the syringe body 41 to the patient P through the tube 44 and the indwelling needle 45.

[0048] Fig. 5 is a block diagram showing an example of the control configuration of the medical pump 3. The control configuration of the medical pump 3 is constituted by an electronic circuit mainly using semiconductor circuit elements arranged inside the medical pump 3. As shown in Fig. 5, the control unit 351 of the medical pump 3 is directly or indirectly connected to a communication unit 352, a storage unit 354, a display unit 321, an input unit 322, a notification unit 358, the motor 36, and a bus 359 or the like to perform communication or drive control.

[0049] The control unit 351 may be configured to include any one or more of processing devices such as a CPU, an MPU, a GPU, an FPGA, a DSP, and a quantum processor. The control unit 351 reads and executes a pump program (or program product) 3541 stored in the storage unit 354. The communication unit 352 is a communication module for performing processing related to communication. The communication unit 352 transmits and receives data to and from the information processing apparatus 2 and the like.

[0050] The storage unit 354 includes a volatile storage unit such as RAM, and a non-volatile storage unit such as ROM, HDD, and flash memory. The storage unit 354 can store a program 3541 for controlling the medical pump 3. In this embodiment, the program 3541 may also be referred to as a program product 3541.

[0051] The notification unit 358 is a speaker that emits sound, a light that emits light, or a vibration generating device, and, upon command from the control unit 351, notifies nearby users of various alarm contents by sound, light, or vibration. In addition, if the control unit 351 displays various alarm contents on the display unit 321, this may be done in conjunction with the display of the alarm on the display unit 321.

[0052] The medical pump 3 controls the motor 36 based on the flow rate setting received from the information processing device 2, and administers the drug at the set flow rate. The medical pump 3 may also have a function to refrain from administering the drug at an administration rate greater than the set upper limit or less than the set lower limit.

[0053] Figure 6 is a block diagram showing an example configuration of the inspection device 5. The inspection device 5 is, for example, attached to a measurement site on patient P, measures the values ​​of inspection parameters, and notifies the information processing device 2 of the measurement results. As shown in Figure 5, the inspection device 5 may have a control unit 51, a communication unit 52, a storage unit 54, a sensor unit 55, and an AD (Analogue Digital) conversion unit 56. The configurations of the control unit 51, communication unit 52, and storage unit 54 can be the same as those of the information processing device 2 in Figure 2, so redundant explanations are omitted.

[0054] The AD conversion unit 56 converts the analog signal from the sensor unit 55 into a digital signal and notifies the control unit 51. The control unit 51 temporarily stores the converted digital signal in the storage unit 54 and then notifies the information processing device 2 via the communication unit 52. Here, prior to notification, predetermined calculations such as unit conversion may be performed on the measurement result.

[0055] The sensor unit 55 can, for example, be a pressure gauge that measures the pressure inside the cuff (armband) and a pressure gauge that detects pulsation when the testing device 5 is a cuff sphygmomanometer. The control unit 51 senses both pressures simultaneously to sequentially acquire the systolic and diastolic blood pressure.

[0056] Furthermore, the values ​​of the test parameters may be directly input into the information processing device 2 without using the testing device 5. For example, in the case of test parameters such as urine volume, where digital information cannot be obtained by visual measurement, the values ​​can be directly input into the information processing device 2. Even when using the testing device 5, the measured values ​​may be confirmed visually and directly input into the information processing device 2.

[0057] The information processing device 2 can acquire values ​​of test parameters through communication from the testing device 5 or through input from the input unit 27. The acquired values ​​of test parameters can be, for example, blood pressure, urine volume, lactate level, body temperature, RASS (Richmond Agitation-Sedation Scale: assessment of sedation), potassium level, blood glucose level, cardiac output, drug concentration in the blood, blood oxygen concentration, APTT (Activated Partial Thromboplastin Time), etc.

[0058] Here, although the infusion volume is not a test item, it affects the test value, so in this embodiment, it can be included as one of the test parameter values. The infusion volume may be the infusion volume in the controlled medical pump 3 or infusion bag, or it may be the infusion volume of the medical pump 3 that is not controlled. The information processing device 2 may obtain the infusion volume of the medical pump 3 from the medical pump 3 via communication, or it may be input via the input unit 27 of the information processing device 2.

[0059] Figure 7 is a flowchart illustrating an example of the control process in the flow rate control plan. First, the information processing device 2 obtains the patient's name from the patient database 242 and displays the patient selection screen 71 (see Figure 8), accepting the patient's selection (step S11). Next, the information processing device 2 obtains the data of the selected patient P from the patient database 242 (step S12).

[0060] The information processing device 2 generates and displays a flow rate control plan 7221 (see Figure 9) for the medical pump 3 based on the patient P's data. In generating the flow rate control plan 7221, for example, if the patient database 242 contains flow rate control information, the information processing device 2 can generate a flow rate diagram, which is the flow rate control plan 7221, based on the flow rate control information contained in the acquired patient P data, since this is the flow rate control information for the medical pump 3 from when the patient P underwent similar treatment in the past. In this case, if the "examination parameter" is "blood pressure" (or "mean blood pressure"), the device may also generate thresholds and target control ranges by referring to the latest patient P's blood pressure (systolic blood pressure / diastolic blood pressure) stored in the "blood pressure" field.

[0061] Furthermore, if the patient database 242 does not contain flow control information, the threshold and adjustment amount may be determined based on the information described in the drug guidelines or the drug's package insert, taking into account physical information such as gender, age, weight, disease, and blood pressure. For example, the dose of norepinephrine can be determined within the range of the following formula, taking into account body weight: Dose (ml / h) = Body weight (kg) × 0.0375 to Body weight (kg) × 0.375

[0062] In this way, the information processing device 2 can receive the patient P's physical information contained in the patient P's data from the patient database 242, and determine the conditions for changing the flow rate of the drug administered in the flow control plan based on the physical information. This makes it possible to create a flow control plan that takes physical information such as weight into consideration.

[0063] Alternatively, for example, flow rate control information, including thresholds and change amounts, may be determined based on the physical information that most closely matches the patient information in the patient database 242. Alternatively, a learning model may be used with patient status data, administered medications, and flow rate control information as training datasets. This allows for the acquisition of flow rate control information by inputting patient status data into the learning model.

[0064] The information processing device 2 generates and displays a flow control diagram, which is the flow control proposal 7221, from the obtained flow control information (step S13). The information processing device 2 can also display a graph showing the time change of inspection parameters on the same screen as the screen on which the flow control proposal 7221 is displayed. On the screen on which the flow control proposal 7221 is displayed, the information processing device 2 accepts input for modification of the flow control proposal (step S14). The information processing device 2 also determines on the screen on which the flow control proposal 7221 is displayed whether it has received a request to display the detailed setting screen 73 (see Figure 10) or an instruction to make a decision (step S17).

[0065] If the information processing device 2 determines that it has received a request to display the detailed settings screen 73 (step S17: display request), it displays the detailed settings screen 73 and accepts the change to the detailed settings item (step S18). The detailed settings screen 73 will be described in detail in the explanation of the example of the detailed settings screen 73 in Figure 10. Once the change to the detailed settings item is accepted, the device returns to the screen displaying the flow rate control proposal in step S14 and repeats the process.

[0066] In step S17, if the information processing device 2 determines that it has received the instruction to make a decision, it instructs the medical pump 3 to operate based on the decided flow rate control plan via the display of the confirmation screen 74 (see Figure 12) (step S19). The confirmation screen 74 will be described in detail in the explanation of the example of the confirmation screen 74 in Figure 12. The medical pump 3 receives the instruction to operate and starts operating based on the instruction. At this point, when issuing the instruction to operate, the information processing device 2 can save the flow rate control information of the decided flow rate control plan to the record corresponding to patient P in the patient database 242.

[0067] The information processing device 2 monitors the values ​​of the inspection parameters received by the inspection device 5, the input unit 27, or other devices, and determines whether the values ​​of the inspection parameters satisfy the threshold conditions of the flow rate control plan (step S22). Whether the threshold conditions are satisfied may be determined, for example, by whether a measurement value exceeding the threshold is detected for a predetermined period of time or for a predetermined number of measurements. Specifically, for example, the threshold conditions may be satisfied by detecting a measurement value exceeding the threshold for 10 consecutive minutes, or by detecting a measurement value exceeding the threshold 10 times in a row. The conditions for satisfying the threshold conditions can be set, for example, in the detailed settings screen 73 (see Figure 10), which will be described in detail in the explanation of the example of the detailed settings screen 73 in Figure 10.

[0068] If the device determines that the value of the test parameter satisfies the threshold condition of the flow rate control plan (Step S22: YES), the information processing device 2 sends an instruction to the medical pump 3 to change the flow rate by the amount of change specified in the flow rate control plan (Step S23). If the device determines that the value of the test parameter does not satisfy the threshold condition of the flow rate control plan (Step S22: NO), or if an instruction to change the flow rate has been sent to the medical pump 3, the information processing device 2 determines whether there has been an instruction to terminate the administration of the drug (Step S24).

[0069] If it is determined that there is an instruction to terminate drug administration (Step S24: YES), the information processing device 2 instructs the medical pump 3 to control the flow rate at the end (Step S25), and terminates the process. Here, the flow rate control at the end can be a control such as gradually reducing the flow rate. If it is determined that there is no instruction to terminate drug administration (Step S24: NO), the information processing device 2 determines whether the target control range remains outside the predetermined time range after a predetermined time has elapsed (Step S27). The predetermined time may be, for example, one set on the detailed settings screen 73.

[0070] If it is determined that the predetermined time has not elapsed or that the system is still within the target control range (step S27: NO), the process returns to step S22 and is repeated. If it is determined that the system is still not within the target control range even after the predetermined time has elapsed (step S27: YES), the information processing device 2 generates and displays a new flow rate control plan (step S28). The case where the system is still not within the target control range even after the predetermined time has elapsed will be described in detail in the explanations of Figures 14 and 15.

[0071] On the screen displaying the new flow control proposal, the information processing device 2 accepts input indicating whether or not to adopt the new flow control proposal (step S29). If input indicating that the new flow control proposal will be adopted is received (step S29: YES), the information processing device 2 returns to step S14 and repeats the same operation as when the initial flow control proposal was displayed. If input indicating that the new flow control proposal will not be adopted is received (step S29: NO), the information processing device 2 returns to step S22 and repeats the process.

[0072] As described above, the flow rate control plan for the medical pump 3 includes a target control range for the values ​​of the inspection parameters. If the information processing device 2 detects that the medical pump 3 is not continuously within the target control range after a predetermined period of time while operating based on the flow rate control plan, it can display a different flow rate control plan. This allows the system to determine if the values ​​of the inspection parameters are not within the target control range and to display a new flow rate control plan that brings them within the target control range. As a result, the user can grasp the patient P's condition at an appropriate time and take appropriate action based on the new flow rate control plan.

[0073] Figure 8 shows an example of a patient selection screen 71. The information processing device 2 refers to the patient database 242 and, for example, displays the name of a registered patient P and displays a patient selection screen 71 that accepts the selection of any patient.

[0074] Figure 9 shows an example of the flow rate control proposal display screen 72. As shown in Figure 9, the flow rate control proposal display screen 72 has a patient trend display area 721 and a flow rate control proposal display area 722. The patient trend display area 721 displays a graph showing the time change of the values ​​of the test parameters input to the information processing device 2. If there are two or more types of test parameter values ​​to be input, the information processing device 2 can overlay them as graphs on the same time axis. In the example in Figure 9, two types of test parameters, blood pressure and urine volume, are displayed overlaid as graphs on the same time axis.

[0075] In this way, the information processing device 2 can display a time-series graph showing the temporal changes in the patient P's examination parameter values ​​on the screen displaying the flow rate control plan (flow rate control plan display screen 72). This allows the user to consider the flow rate control plan while referring to the examination parameter values, and to arrive at a more appropriate flow rate control plan.

[0076] Furthermore, the test parameters are not limited to test items. For example, one of the test parameter values ​​may include the amount (flow rate or total dose) administered by the medical pump 3 or the amount (flow rate or total dose) of medication administered by a drug other than the medical pump 3, which affects the test results. In the example in Figure 9, blood pressure and urine output are used as test parameters, but other test parameters can be used.

[0077] The flow rate control proposal display area 722 includes a flow rate control proposal 7221, a detailed setting button 7222, and a confirmation button 7223. The flow rate control proposal 7221 is generated and displayed by the information processing device 2 based on the record of the selected patient P in the patient database 242. In this embodiment, the flow rate control proposal 7221 is displayed as a diagram (hereinafter referred to as the "flow rate control diagram") in which the set flow rate is determined with the threshold as the axis, using the threshold-related inspection parameter as the boundary. However, it may also be displayed as a diagram, table, or graph.

[0078] In the flow control diagram of the proposed flow control method in Figure 9, it is shown that when the mean blood pressure is between 69 and 73 mmHg, the flow rate is maintained at a standard rate determined for each patient. Although the standard flow rate is not shown in Figure 9, it may be shown. The range in which the standard flow rate is maintained (between 69 and 73 mmHg in Figure 9) can be defined as the target control range.

[0079] Furthermore, in the flow rate control plan 7221 shown in Figure 9, it is indicated that if the mean blood pressure exceeds 73 mmHg, the flow rate should be reduced by 1.0 ml / h, and if it exceeds 75 mmHg, the flow rate should be reduced by 1.5 ml / h. In addition, in the flow rate control plan 7221, it is indicated that if the mean blood pressure falls below 69 mmHg, the flow rate should be increased by 1.0 ml / h, and if it falls below 65 mmHg, the flow rate should be increased by 2.0 ml / h.

[0080] The values ​​65, 69, 73, and 75 mmHg are thresholds for controlling the flow rate, and are displayed using text boxes 7224 on the flow rate control display screen 72, allowing users such as doctors to modify and input them. In Figure 9, the mean blood pressure threshold is shown as being modifiable, but the flow rate to be changed may also be modifiable.

[0081] If the flow rate control plan 7221 is generated based on flow rate control information (patient database 242) of patient P or a patient judged to be similar to patient P, the information processing device 2 may display a graph in the patient trend display area 721 showing the changes in the past examination parameters of the corresponding patient.

[0082] The confirmation button 7223 accepts touch or click operations when the user wants to start flow control of the medical pump 3 using the displayed flow control plan after making the necessary changes. The detailed settings button 7222 accepts operations to display the detailed settings screen 73.

[0083] Figure 10 shows an example of the detailed settings screen 73. When the information processing device 2 receives an operation of the detailed settings button 7222 on the flow rate control proposal display screen 72, it displays the detailed settings screen 73 on the display unit 26. As shown in Figure 10, the detailed settings screen 73 has a reference blood pressure area 731, a condition determination area 732, an alert notification condition area 733, an other area 734, a flow rate upper and lower limit area 735, and a confirm button 739.

[0084] The reference blood pressure area 731 can be displayed by the information processing device 2 when blood pressure is included in the examination parameters to be acquired. The reference blood pressure area 731 is an area for selecting whether to acquire blood pressure measured by an A-line, blood pressure measured by a cuff, or blood pressure measured by both. An A-line is a method of measuring blood pressure by inserting a catheter into an artery. A cuff is a pressure band worn on the arm used with a blood pressure monitor, and blood pressure is measured by inflating it with air and adjusting the pressure. In Figure 10, only the A-line is selected.

[0085] Thus, the information processing device 2 can accept user input to select whether to use either or both of the A-line blood pressure and cuff blood pressure values ​​as the blood pressure parameter. By selecting the blood pressure measurement method for the test parameter, the user can select an appropriate blood pressure measurement method according to the patient P's disease or condition.

[0086] The condition determination area 732 sets the conditions for determining when the threshold is exceeded in the flow rate control plan 7221 in Figure 9. Since line A is selected in the reference blood pressure area 731, the condition determination area 732 is the area for setting the conditions for determining when the blood pressure measured by line A has crossed the threshold. In the example in Figure 10, the setting determines how many minutes the condition (value crossing the threshold) must be met (measured) before the flow rate should be changed. In Figure 10, the condition is set to be met for 10 minutes continuously as an example. The time portion is displayed in the text box 738 and can be changed.

[0087] Thus, the information processing device 2 may accept an operation to set a condition for the threshold, namely the time during which the threshold is constant, and determine whether the condition is met according to the accepted setting. This makes it possible to avoid changing the flow rate even if the value of the test parameter momentarily exceeds the threshold, thereby reducing the burden on the patient P caused by frequent flow rate changes.

[0088] The alert notification condition area 733 is where you set the range of abnormal values ​​for alerts that are issued when the value of a test parameter becomes abnormal. In Figure 10, the system is set to notify when the blood pressure, which is a test parameter, is 63 mmHg or less, or 80 mmHg or more. The blood pressure value is displayed in text box 738 and can be changed.

[0089] In this way, the information processing device 2 can accept input of upper and lower limits for the inspection parameters related to the alert output of the medical pump 3. Alerts can be notified using the display unit 26 or speaker (not shown) of the information processing device 2. Alternatively, the information processing device 2 may notify the medical pump 3 of the alert, and the medical pump 3 will notify the alert on its display unit 321 or notification unit 358. This allows the user to be immediately notified if the value of the inspection parameter exceeds the upper limit or falls below the lower limit, enabling appropriate measures to be taken for patient P.

[0090] The other area 734 in Figure 10 contains a setting item for whether or not to use the moving average reference mode. If the moving average reference mode is not selected, the system switches to the instantaneous value reference mode, which references real-time instantaneous values. The other area 734 may also contain setting items other than whether or not to use the moving average reference mode. The moving average reference mode sets whether the value of the inspection parameter to be acquired is referenced as an instantaneous value or as a moving average. In the example in Figure 10, the moving average reference mode is set to OFF, but if the moving average reference mode is set to ON, the information processing device 2 may further display an item for setting the length of time for taking the moving average.

[0091] Thus, the information processing device 2 can accept an operation to set the instantaneous value or moving average value of the test parameter as a condition related to the threshold, and can determine whether the condition is met according to the accepted setting. This makes it possible to suppress frequent changes in flow rate even if, for example, there is a large variation in the instantaneous value depending on the type and condition of the patient P, by using the moving average value. In addition, if it is desired to change the flow rate in response to instantaneous changes in the value of the test parameter, the setting can be configured to use the instantaneous value.

[0092] The flow rate upper and lower limit area 735 is the area where the upper and lower limits of the pump flow rate of the medical pump 3 are set. The information processing device 2 issues an alert when the flow rate of the medical pump 3 exceeds the upper limit or falls below the lower limit. In the flow rate upper and lower limit area 735 of Figure 10, there is an option to set an upper flow rate limit and an option to set a lower flow rate limit. If the option to set an upper flow rate limit is selected, the value of the upper flow rate limit is entered, and if the option to set a lower flow rate limit is selected, the value of the lower flow rate limit is entered and set.

[0093] In the example shown in Figure 10, only the flow rate upper limit is set, and the value is set so that an alert is ignored if the flow rate exceeds 10 ml / h. The flow rate value is displayed in text box 738 and can be changed. In this way, the information processing device 2 can accept input for the upper and lower limits of the flow rate of the medical pump 3. By pre-determining the upper and lower limits of the flow rate for patient P, even if a flow rate unexpectedly exceeds the upper limit or falls below the lower limit during flow rate control operation, the device can prevent fluid delivery at that flow rate.

[0094] Furthermore, if the medical pump 3 has settings to prevent fluid delivery exceeding the upper limit of the flow rate and settings to prevent fluid delivery below the lower limit of the flow rate, the information processing device 2 can set these settings for the medical pump 3. In addition, if fluid delivery is attempted at a flow rate exceeding the upper limit or below the lower limit, the medical pump 3 may issue an alert via the display unit 321 or notification unit 358, etc. The confirmation button 739 accepts the operation to confirm the settings displayed on the detailed settings screen 73 and return to the flow rate control proposal display screen 72.

[0095] As described above, the information processing device 2 can receive an instruction to display a screen for setting detailed items on the screen that displays the flow rate control plan 7221 (flow rate control plan display screen 72), and can accept selection or input on the displayed screen for setting detailed items. By setting the detailed items as described above, the information processing device 2 can achieve precise flow rate control for the medical pump 3 according to the inspection parameters.

[0096] Figure 11 shows another example of the detailed settings screen 73. In the detailed settings screen 73 of Figure 11, the settings for the reference blood pressure area 731 and the condition determination area 732 are different from those of the detailed settings screen 73 of Figure 10, but otherwise it is the same as the detailed settings screen 73 of Figure 10, and the explanation of areas other than the reference blood pressure area 731 and the condition determination area 732 is omitted.

[0097] In the reference blood pressure area 731 of the detailed settings screen 73 in Figure 11, the cuff is enabled in addition to the A-line. As a result, the information processing device 2 changes and displays the way conditions are set in the condition determination area 732. As shown in the condition determination area 732 of Figure 11, when the cuff is enabled in addition to the A-line, first, just as in the case of measurement with the A-line only, the setting is made as to how many minutes the value measured with the A-line must continuously meet the condition (value that crosses the threshold) before it is determined that the threshold has been exceeded. If it is determined that the threshold has been exceeded under the conditions set here, blood pressure measurement is then performed using the cuff. The information processing device 2 acquires the blood pressure measurement value obtained using the cuff, and if it exceeds the threshold, it determines that the value has changed by crossing the threshold.

[0098] Thus, when blood pressure measurement is selected using both the A-line and the cuff, the information processing device 2, upon detecting a value exceeding the threshold for a predetermined period of time using the A-line, further acquires the measurement value from the cuff. If the measurement value from the cuff also exceeds the threshold, it can determine that the blood pressure has changed across the threshold. Upon determining that the blood pressure has changed across the threshold, the information processing device 2 changes the flow rate according to the flow rate control diagram for flow rate control.

[0099] In this way, the information processing device 2 can accept user input to select whether to use the blood pressure measurements from either the A-line, the cuff, or both as the blood pressure parameters for the examination. By allowing the user to select the method for measuring the blood pressure parameters, it becomes possible to select an appropriate blood pressure measurement method according to the patient P's disease or condition. Furthermore, if the user chooses to measure blood pressure using both the A-line and the cuff, the information processing device 2 can perform a measurement using the cuff if the conditions are met in the A-line measurement, and if the conditions are met in the cuff measurement, it can determine that there has been a change that crosses a threshold.

[0100] Figure 12 shows an example of a confirmation screen 74. The information processing device 2 can display the confirmation screen 74 when it receives an operation of the confirmation button 7223 on the flow rate control proposal display screen 72 in Figure 9. As shown in Figure 12, the confirmation screen 74 has an inspection parameter confirmation area 741, a flow rate control confirmation area 742, a threshold determination condition confirmation area 743, and an operation start button 744. The inspection parameter confirmation area 741 displays the inspection parameters acquired by the information processing device 2. The inspection parameter confirmation area 741 may display only the control inspection parameters that are referenced as thresholds in flow rate control.

[0101] The flow rate control confirmation area 742 displays the flow rate control diagram related to the flow rate control to be applied. Specifically, the information processing device 2 displays the flow rate control diagram of the flow rate control plan 7221 when the confirmation button 7223 is operated on the flow rate control plan display screen 72 in Figure 9. The threshold determination condition confirmation area 743 displays the contents set in the condition determination area 732 of the detailed setting screen 73. The confirmation screen 74 may display any item set on the flow rate control plan display screen 72 or the detailed setting screen 73. It may also include items other than those set on the flow rate control plan display screen 72 or the detailed setting screen 73.

[0102] The operation start button 744 receives an instruction to start operation based on the operation control displayed on the confirmation screen 74. The information processing device 2 can save the flow control information for which the operation start instruction has been received to the corresponding patient P record in the patient database 242. In this way, the information processing device 2 instructs the medical pump 3 to operate based on the flow control plan for which an operation has been accepted by the user, such as by the operation start button 744. As a result, the operation of the medical pump 3 can be started by confirmation by the user, thus reducing the occurrence of accidents due to errors in flow rate, etc.

[0103] As described above, in this embodiment, the information processing device 2 receives drug administration information for the medication administered to patient P and laboratory value information for patient P that is affected by the drug administration. Furthermore, based on the threshold values ​​of the laboratory parameters included in the laboratory value information, it displays a flow rate control plan for the medical pump 3 that defines the conditions for changing the flow rate of the medication related to the drug administration information. On the screen where the flow rate control plan is displayed, it accepts input for changing the conditions, including the threshold values, and accepts an operation to confirm operation with the displayed flow rate control plan. This allows the user to set the medical pump 3 in a more understandable and appropriate manner. The operation to confirm here may be performed on a separate screen.

[0104] Figure 13 shows a flow control diagram 7621, which is another example of a flow control plan. In Figure 13, the flow control diagram 7621 is shown as an example of being displayed on the flow control plan display screen 72, similar to that in Figure 9. The flow control plan display area 722, as well as the items of the detailed setting button 7222, the confirm button 7223, and the text box 7224, are the same as the corresponding items in Figure 9, so redundant explanations are omitted.

[0105] The patient trend display area 761 in Figure 13 differs from the patient trend display area 721 in Figure 9 in that it displays the medication volume (infusion volume), which is the flow rate of the medical pump 3, as one of the examination parameters, in addition to the examination parameters of blood pressure and urine output. By adopting the flow rate (infusion volume) of the medical pump 3 as one of the examination parameters, as in the patient trend display area 761 in Figure 13, the flow rate (infusion volume) of the medical pump 3 can be displayed on the same time axis graph as the other examination parameters, allowing the user to grasp the effect of the flow rate (infusion volume) of the medical pump 3 at a glance. This makes it possible to set appropriate values ​​for the setting items (thresholds, etc.) of the flow rate control proposal.

[0106] The information processing device 2 may display a graph in the patient trend display area 761 showing when the flow rate control information of the patient P themselves or other patients P with similar physical information, etc., from the patient database 242 was used. In addition, if the medical pump 3 is operating, the information processing device 2 can display a graph showing the examination parameters, including the flow rate of the drug being administered by the medical pump 3.

[0107] In the flow control proposal (flow control diagram) 7221 shown in Figure 9, only blood pressure is used as the test parameter referenced as the threshold for flow rate change. However, multiple test parameters may be used as the threshold for flow rate change. In the flow control diagram 7621 shown in Figure 13 as a flow control proposal, two test parameters, blood pressure and urine volume, are used as the threshold. As a result, the information processing device 2 can display a two-dimensional flow control diagram 7621.

[0108] In the example in Figure 13, it is shown that the standard flow rate should be maintained when, for example, the urine output per hour is 50-100 ml / h and the mean arterial pressure is 68-78 mmHg, when the urine output per hour is 100-200 ml / h and the mean arterial pressure is 65-68 mmHg, and when the urine output per hour is 200 ml / h or more and the mean arterial pressure is 65-78 mmHg. It is also shown that, for example, if the urine output per hour is 50-100 ml / h and the mean arterial pressure falls below 68 mmHg, the flow rate should be increased by 1 ml / h, and if the urine output per hour is 100 ml / h or more and the mean arterial pressure falls below 65 mmHg, the flow rate should be increased by 0.5 ml / h.

[0109] Furthermore, it has been shown that if the urine output per hour is 50-200 ml / h and the mean arterial pressure exceeds 78 mmHg, the flow rate should be reduced by 1 ml / h. It has also been shown that if the urine output per hour is 100-200 ml / h and the mean arterial pressure is 68-78 mmHg, and if the urine output per hour is 200 ml / h or more and the mean arterial pressure exceeds 78 mmHg, the flow rate should be reduced by 0.5 ml / h.

[0110] As described above, the information processing device 2 can display a flow rate control proposal for the medical pump 3 by displaying a two-dimensional graph based on two types of test parameters. Alternatively, it may display a flow rate control proposal based on two or more types of test parameters. This allows for flow rate control that takes into account the effects of multiple test parameters when a drug affects multiple test parameters.

[0111] Figure 14 is an explanatory diagram of an example of displaying flow rate control proposals during operation. Figure 14 shows the operation screen 77 and the operation flow rate control proposal display screen 78 that is displayed after the operation screen 77. The operation screen 77 has a patient trend display area 771 and an operation flow rate control display area 772. The patient trend display area 771, like the patient trend display area 721 of the flow rate control proposal display screen 72 in Figure 9, displays a graph showing the time change of the values ​​of the examination parameters input to the information processing device 2. If there are two or more types of examination parameters to be input, the information processing device 2 can display them superimposed as graphs on the same time axis.

[0112] In this way, the information processing device 2 can display, as a time-series graph, a graph showing the time change in the patient's test parameter values ​​included in the test value information, and information showing the timing of the change in flow rate and the changed flow rate, all aligned on a single time axis. This allows the user to immediately consider whether the flow rate control (flow rate control diagram) is appropriate while referring to the test parameter values, and to apply more appropriate flow rate control.

[0113] The flow rate control display area 772 during operation includes a flow rate control diagram 7721, a detailed setting button 7722, a control value change button 7723, and an exit button 7724. The flow rate control diagram 7721 displays, for example, the flow rate control diagram (flow rate control proposal) 7221 determined on the flow rate control proposal display screen 72 in Figure 9.

[0114] The detailed settings button 7722 accepts an operation to display the detailed settings screen 73 (see Figure 10), similar to the detailed settings button 7222 on the flow rate control plan display screen 72. The detailed settings items on the detailed settings screen 73 may be changeable even while the medical pump 3 is running, or some items may not be changeable while running. The control value change button 7723 accepts an operation to display a screen similar to the flow rate control diagram (flow rate control plan) 7221 on the flow rate control plan display screen 72 in Figure 9.

[0115] The screen similar to the flow control diagram (flow control plan) 7221 is for changing the setting values ​​such as the threshold value of the inspection parameter and the flow rate that will be changed when it is determined that the value of the inspection parameter has crossed the threshold. The end button 7724 accepts the instruction to end the administration of the drug. Upon termination, the information processing device 2 may perform predetermined flow control, such as gradually reducing the flow rate of the drug administered by the medical pump 3.

[0116] Here, in the patient trend display area 771 of Figure 14, the target control range for mean blood pressure is 69-73 mmHg, and it can be seen that the mean blood pressure trend has not remained within the target control range even after a predetermined time has elapsed. In this way, if the information processing device 2 detects that the mean blood pressure has not remained within the target control range after a predetermined time, it can display a flow control proposal with a flow control diagram different from the current flow control diagram.

[0117] In the patient trend display area 771, when the mean blood pressure is lower than the target control range, the information processing device 2 controls the flow rate of medication administered by the medical pump 3, causing the mean blood pressure to tend to exceed the target control range. Conversely, when the mean blood pressure exceeds the target control range, the information processing device 2 controls the flow rate of medication, but the mean blood pressure then falls below the target control range. In other words, the mean blood pressure tends to fluctuate up and down across the target control range.

[0118] The operational flow control plan display screen 78 in Figure 14 is a screen displayed when the information processing device 2 detects that the flow rate has not remained within the target control range for a predetermined period of time. The operational flow control plan display screen 78 has an operational flow control display area 781, a patient trend display area 782, and a flow control plan display area 783. The operational flow control display area 781 displays the same information as the flow control diagram 7721 in the operational flow control display area 772 of the operational screen 77. The patient trend display area 782 displays the same information as the patient trend display area 771 of the operational screen 77.

[0119] The flow control proposal display area 783, the detailed setting button 7832, and the confirm button 7833 are displayed in the same way as the flow control proposal display area 722, detailed setting button 7222, and confirm button 7223 on the flow control proposal display screen 72 in Figure 9, respectively, and redundant explanations are omitted. The back button 7834 is a button that accepts the operation to return to the operation screen 77 without applying the displayed flow control proposal. The information processing device 2 displays a flow control proposal (flow control diagram) 7831 different from the current flow control diagram in the flow control proposal display area 783.

[0120] The information processing device 2 can determine that the amount of unit change when changing the flow rate is too large based on the mean blood pressure trend which moves up or down beyond the target control range, and can display a flow rate control diagram 7831 that reduces the amount of unit change when changing the flow rate.

[0121] The flow rate control diagram may also be output by a learning model. The information processing device 2 can generate a flow rate control diagram using the learning model. In this case, the learning model can be trained using training data consisting of a flow rate control diagram, the time change of mean blood pressure based on the flow rate control diagram, and the modified flow rate control diagram. The information processing device 2 can output a flow rate control plan by inputting the flow rate control diagram and the time change of mean blood pressure based on the flow rate control diagram into the trained learning model.

[0122] As described above, a flow control plan different from the flow control diagram currently in operation can include changes to the unit change amount when the flow rate is changed. This allows for earlier changes to the flow control diagram with appropriate unit change amounts, even if the unit change amount when the flow rate is changed is inappropriate in the flow control diagram currently in operation.

[0123] In this configuration, since flow control options can be presented during operation, users can be made aware that flow control should be changed if it is not necessarily appropriate. Furthermore, users can be made aware of what kind of flow control changes are most likely to be appropriate.

[0124] Figure 15 is an explanatory diagram of another example of displaying flow rate control proposals during operation. Similar to Figure 14, Figure 15 shows the operation screen 77 and the operation flow rate control proposal display screen 78 that is displayed after the operation screen 77. In Figure 15, the graph showing the changes in examination parameters displayed in the patient trend display area 771 of the operation screen 77 is different from the corresponding graph in Figure 14, so the flow rate control proposal (flow rate control diagram) that the information processing device 2 displays in the flow rate control proposal display area 783 of the operation flow rate control proposal display screen 78 is different.

[0125] The explanations for the detailed setting button 7832, the confirm button 7833, and the back button 7834 in the operational flow rate control display area 772 of the operational screen 77, the operational flow rate control display area 781 of the operational flow rate control proposal display screen 78, the patient trend display area 782, and the flow rate control proposal display area 783 are the same as those for the corresponding areas in Figure 14, so the explanations are omitted.

[0126] Here, in the patient trend display area 771 of Figure 15, the target control range for mean blood pressure is 69-73 mmHg, and it can be seen that the mean blood pressure trend has not remained within the target control range even after a predetermined time has elapsed. In this way, if the information processing device 2 detects that the mean blood pressure has not remained within the target control range after a predetermined time, it can display a flow control proposal with a flow control diagram different from the current flow control diagram.

[0127] In the patient trend display area 771 of Figure 15, the mean blood pressure is gradually rising while remaining below the target control range, but it does not reach the target control range of 69-73 mmHg within a predetermined time. The information processing device 2 analyzes this trend and can display a flow control proposal, for example, a flow control diagram 7831 that sets a higher flow rate when the mean blood pressure is lower. In the flow control diagram 7831 of Figure 15, a control is added that increases the flow rate by 3.0 ml / h when the mean blood pressure falls below 50 mmHg.

[0128] As described above, a flow control proposal different from the flow control diagram currently in operation may include changes to the threshold values ​​of the inspection parameters compared to the flow control diagram currently in operation. This allows for earlier changes to the flow control diagram with appropriate inspection parameter thresholds, even if the threshold values ​​of the inspection parameters in the flow control diagram during flow rate changes were inappropriate.

[0129] Furthermore, since the information processing device 2 has only increased the flow rate once in the patient trend display area 771 of Figure 15, it may change the flow rate control to change the flow rate change cycle from 10 minutes to 3 minutes, etc. In this case, the flow rate change cycle may be changed in the detailed settings screen 73.

[0130] As described above, a flow control plan different from the flow control diagram currently in operation can include changes to the time cycle of flow rate changes compared to the flow control diagram currently in operation. This allows for earlier changes to the flow control diagram with an appropriate time cycle, even if the time cycle of flow rate changes in the current flow control diagram is inappropriate.

[0131] In this way, the information processing device 2 can display a flow control diagram 7831 that is different from the current flow control diagram in the flow control diagram display area 783 of the flow control diagram display screen 78 during operation.

[0132] In this way, since flow control proposals can be presented during operation, it is possible to make users aware that flow control should be changed if it is not necessarily appropriate. It is also possible to understand what kind of flow control changes are most likely to be appropriate.

[0133] Furthermore, as described above, the information processing device 2 receives drug administration information for the medication administered to patient P and laboratory value information for patient P that will be affected by the drug administration. It also displays a flow rate control plan for the medical pump 3, which defines conditions for changing the flow rate of the medication related to the drug administration information based on the threshold values ​​of the laboratory parameters included in the laboratory value information. On the screen where the flow rate control plan is displayed, it accepts input for changing the conditions, including the threshold values, and accepts an operation to confirm operation with the displayed flow rate control plan. This allows the user to configure the medical pump 3 in a more understandable and appropriate manner. The operation to confirm here may be performed on a separate screen.

[0134] The forms of this disclosure are illustrative in all respects and not restrictive. The scope of the invention is not limited to those shown in the above disclosure but is shown by the claims, and all modifications within the meaning and scope of the equivalents of the claims are intended.

[0135] The matters described in each embodiment can be combined with each other. Furthermore, the independent and dependent claims described in the claims can be combined with each other in any combination, regardless of the form of reference. In addition, although the claims do not use the form of a multi-claim that further references a multi-claim (multi-multi-claim), it may be a combination that uses the form of a multi-multi-claim that references all higher-level claims.
