Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described. FIG. 1 is a diagram showing an example of the configuration of the display system of the present embodiment. The display system includes a display device 50 and a plurality of pumps (medical pumps) 11 and 21. The pumps 11 and 21 are connected to the display device 50 via various communication networks such as serial communication, Bluetooth (registered trademark), NFC (Near Field Communication), wired LAN, or wireless LAN. The display device 50 is connected to a data server 70 via a communication network 1.

[0011] The pumps 11 and 21 include a syringe pump for injecting a relatively small amount of drug and an infusion pump for injecting a relatively large amount of drug. At least one of the pumps 11 and 21 has a so-called PCA function. The PCA function is a function that, in order to cope with pain relief therapy, in addition to the administration (continuous administration) of one of the drugs prescribed by a doctor, allows the patient himself / herself to additionally administer (PCA administration, bolus administration) the other drug, or allows a medical staff member to additionally administer (rescue administration).

[0012] The pump 11 administers the drug A contained in the infusion bag 10 through the tube and the indwelling needle 12 indwelling in the patient's blood vessel. The pump 21 administers the drug B contained in the infusion bag 20 through the tube and the indwelling needle 22 indwelling in the blood vessel of the patient. The drug A is a drug that has no immediate effect but is effective for continuous pain relief, and the drug B can be a drug with immediate effect, but is not limited thereto. The pumps 11 and 21 output the administration information of the drug to the display device 50. Although not shown, the pumps 11 and 21 may transmit the administration information of the drug to the data server 70 and record the administration information of the patient in the in-hospital DB 71. Details of the administration information will be described later.

[0013] The display device 50 includes a control unit 51 that controls the entire display device 50, a communication unit 52, a memory 53, a display unit 54, an operation unit 55, and a storage unit 56. The display device 50 can be composed of a computer, a tablet terminal, a smartphone, etc. The display device 50 is used by medical staff such as nurses, doctors, and clinical engineering technicians (ME).

[0014] The control unit 51 may be configured by incorporating a required number of CPUs (Central Processing Units), MPUs (Micro-Processing Units), GPUs (Graphics Processing Units), etc. Also, the control unit 51 may be configured by combining DSPs (Digital Signal Processors), FPGAs (Field-Programmable Gate Arrays), etc.

[0015] The communication unit 52 includes a communication module and has a function of communicating with the data server 70 via the communication network 1. Also, the communication unit 52 has a communication function with the pumps 11 and 21. The display device 50 (control unit 51) receives (acquires) the drug administration information of the pumps 11 and 21 via the communication unit 52. Also, the display device 50 (control unit 51) may access the in-hospital DB 71 to acquire the past drug administration information of the pumps 11 and 21.

[0016] The display unit 54 can be composed of a liquid crystal panel or an organic EL (Electro Luminescence) display, etc.

[0017] The operation unit 55 includes, for example, a keyboard, a mouse, etc., and can perform operations such as icons displayed on the display unit 54, movement and operation of the cursor, input of characters, etc. The operation unit 55 may be composed of a touch panel.

[0018] The storage unit 56 can be composed of a hard disk or a semiconductor memory, etc., and stores a computer program 57 (program product), a learning model 58, and required information.

[0019] The computer program 57 is an application program for managing a medical pump. Specifically, it can visualize, for example, by graphing the drug dosage administered by the medical pump, and can also set the dosage. The computer program 57 may be downloaded from an external device via the communication unit 52 and stored in the storage unit 56. Alternatively, the computer program 57 recorded on a recording medium (for example, an optical readable disk storage medium such as a CD-ROM) may be read by the recording medium reading unit and stored in the storage unit 56. The computer program 57 can be deployed to be executed on a single computer, or on one site, or on a plurality of computers distributed across a plurality of sites and interconnected by a communication network. Also, the computer program 57 may be operable after the communication network is disconnected after being operably set. Details of the learning model 58 will be described later.

[0020] The memory 53 can be composed of a semiconductor memory such as SRAM (Static Random Access Memory), DRAM (Dynamic Random Access Memory), or flash memory. The computer program 57 can be deployed in the memory 53 and the control unit 51 can execute the computer program 57. The control unit 51 can execute the processes defined by the computer program 57. That is, the processes by the control unit 51 are also the processes by the computer program 57.

[0021] The data server 70 includes an in-hospital DB (database) 71. The in-hospital DB 71 records history information such as a patient's examination records, test records, treatment records, surgical records, and medication records for each patient. The history information also includes information such as predicted blood drug concentration values. The control unit 51 can access the in-hospital DB 71 to obtain the patient's history information.

[0022] FIG. 2 is a diagram showing an example of administration information of a drug that can be obtained from a medical pump. The administration information includes a drug code (drug name), a reference flow rate, upper and lower limits of the flow rate, a dose, a remaining amount in the syringe, the number of additional administrations, validity / invalidity of additional administrations, a refractory period, and the like. The reference flow rate is the flow rate per hour (mL / h), and a speed corresponding to the drug is set. The dose is the required amount (mL) of the drug to be administered to the patient in one treatment. The syringe is, for example, a syringe with a size of 5 mL or 10 mL, and can administer the drug at a low flow rate and is used to relieve cancer pain and postoperative pain.

[0023] For drug administration, there are continuous administration in which a medical staff continuously administers at a flow rate per hour set in advance, and additional administration in which an additional dose is administered in addition to the continuous administration. The additional administration includes a bolus administration (PCA administration) that the patient himself / herself can additionally administer when in pain, and a rescue administration that a medical staff additionally administers as judged necessary. Generally, for continuous administration, a drug that can continuously relieve pain is used, and for additional administration, a drug with high immediacy is used. That is, the drug for continuous administration and the drug for additional administration are different. The refractory period is set to prevent over-administration and is the time during which PCA administration is not accepted for a certain period of time, and times such as 15 minutes, 30 minutes, 45 minutes, 1 h, 1.5 h, 2 h can be set. The additional administration outside the refractory period is effective, but the additional administration within the refractory period is invalid and cannot be additionally administered.

[0024] FIG. 3 is a diagram showing an example of processing by the learning model 58. The control unit 51 acquires administration information of each of a plurality of drugs administered to the patient by the plurality of pumps 11 and 21. The administration information may be acquired from the pumps 11 and 21 or from the in-hospital DB 71. The control unit 51 inputs the acquired administration information into the learning model 58.

[0025] The learning model 58 is generated (learned) to output at least one of the current and future pain indices (required time points) when drug administration information is input. The pain index is an index representing the "pain level" and can be expressed, for example, on a 5-point scale (pain level: 1 to 5). It can be assumed that the greater the pain level, the stronger the pain. Note that the pain index may be expressed as a numerical value such as 0 to 100 (%) instead of on a 5-point scale.

[0026] The learning model 58 can use, for example, SVM (Support Vector Machine), decision tree, random forest, AdaBoost, Bayesian classifier, neural network (e.g., RNN: Recurrent Neural Network, LSTM: Long Short Term Memory, etc.).

[0027] When the drug administration information is input, the control unit 51 can input the acquired administration information to the learning model 58 that outputs at least one of the current and future pain indices, and obtain the pain index at the required time point output by the learning model 58.

[0028] In addition, the control unit 51 acquires training data including drug administration information and at least one of the current and future pain indices. The drug administration information is time-series data from the past to the present. The pain index may be the current pain index. From the perspective of drug metabolism during treatment, it is mainly about several hours, one day, or about three days from the current time. However, for data utilization, it may also be a future pain index such as one week later, one month, two months, six months, or one year later. The training data identifies the drug administration information from the drug administration histories of a plurality of patients, identifies the pain indices at the required time points (current or future) of each of the plurality of patients, and collects the identified administration information and pain indices in association with each other. Based on the acquired training data, the control unit 51 generates a learning model so as to output at least one of the current and future pain indices when drug administration information is input. Note that the generation of the learning model 58 may be performed by the display device 50. However, the learning model 58 may be generated (learned) by another learning processing device, and the control unit 51 may acquire the generated learning model 58 from the learning processing device and store it in the storage unit 56. Therefore, the learning model 58 may be generated separately. Furthermore, the result output by the learning model 58 may be applied to another device or program. The display device 50 may include the learning model 58 or may generate the learning model 58. Also, the computer program 57 operating on the display device 50 and the display method by the display device 50 may use the learning model 58 or may generate the learning model 58.

[0029] Next, a method for visualizing the drug administration amounts and the like by the pumps 11 and 21 by the display device 50 of the present embodiment will be described.

[0030] FIG. 4 is a diagram showing a first example of a drug dosage display screen 100. On the display screen 100, there is a selection column for selecting a patient ID, and the drug dosage information of the patient targeted for pain management (in the example of the figure, patient ID: 012345) is displayed. As shown in FIG. 4, as the drug dosages, the continuous dosage [mL], PCA dosage [mL], rescue dosage [mL], priming volume [mL], cumulative continuous dosage [mL], and cumulative PCA dosage [mL] are illustrated. Priming is an operation for removing air bubbles so that the drug solution reaches the tip of the tube. The continuous dosage and the cumulative continuous dosage are based on the administration of drug A administered by pump 11, and the PCA dosage, rescue dosage, priming volume, and cumulative PCA dosage are based on the administration of drug B administered by pump 21. Drug A is a drug that has no immediate effect but is effective for continuous pain relief, and drug B can be a drug with immediate effect.

[0031] The vertical axis of the graph indicates the dosage and cumulative amount, the horizontal axis indicates time, and the continuous dosage, PCA dosage, rescue dosage, priming volume, cumulative continuous dosage, and cumulative PCA dosage per hour during a one-day period from 00:00 to 23:59 are calculated and displayed.

[0032] As shown in FIG. 4, based on the administration information obtained from the plurality of pumps 11 and 21, the dosages of drugs A and B (continuous dosage and additional dosage) are integrated equally into one graph and displayed on the same time series.

[0033] As described above, the control unit 51 acquires the administration information of each of the plurality of drugs (A, B) administered to the patient by the plurality of pumps 11 and 21, calculates the dosage of each of the plurality of drugs based on the acquired administration information, and displays the dosages of each of the plurality of drugs in a time series and in a comparable manner. The dosage can be obtained by the formula dosage [mL] = reference flow rate [mL / h] × unit time [h]. Displaying in a comparable manner means displaying the plurality of drugs in a display mode that allows comparison.

[0034] Conventionally, when multiple pumps are used, separate graph displays are provided for each pump. Therefore, without comparing the times displayed on each display screen and aligning the times, it is impossible to grasp the dosage and administration timing of multiple drugs. However, in this embodiment, since the dosage of each of the multiple drugs is displayed in a time series and can be compared, the dosage and administration timing of the multiple drugs can be easily grasped, which helps to reduce the burden on medical staff and supports pain management in which multiple types of drugs are simultaneously administered using multiple medical pumps.

[0035] In addition, the control unit 51 can display the dosage of each of the multiple drugs in a time series using a common time axis within a single display screen. As a result, the difference between a continuously administered drug and an additional administered drug can be easily distinguished on the common time axis, and the difference in the dosage of the multiple drugs and the dosage at the same timing can be easily grasped.

[0036] Further, the control unit 51 can calculate the cumulative dosage of each of the multiple drugs based on the acquired administration information, and display the cumulative dosage of each of the multiple drugs in a time series and in a comparable manner. As a result, the difference in the cumulative dosage of each of the multiple drugs and the cumulative dosage at the same timing can be easily grasped.

[0037] As shown in FIG. 4, a medical staff member can display detailed information on the dosage at a given timing in the pop-up window 102 by moving the cursor 101 to the graph at the desired timing. In the example of FIG. 4, the continuous dosage, PCA dosage, rescue dosage, fast-forward dosage, continuous cumulative dosage, and PCA cumulative dosage during the one-hour period from 05:00 to 05:59 on September 21, 2020 are displayed.

[0038] As described above, when the control unit 51 receives an operation (for example, cursor movement) on the graph of the drug dosage per unit time displayed within a single display screen, it can display detailed information on the drug dosage at that time. As a result, the details of the drug dosage can be grasped.

[0039] FIG. 5 is a diagram showing a second example of the display screen 110 for drug dosage. On the display screen 110, a PCA display area 111 is displayed. In the PCA display area 111, the number of PCA administrations and the effectiveness / ineffectiveness of PCA administrations are displayed. In the example of FIG. 5, one effective PCA injection was performed between 00:00 and 00:59, and one effective PCA injection was performed between 03:00 and 03:59. Also, between 04:00 and 04:59, three PCA injections were performed. The first PCA injection was effective, but the second and third PCA injections were ineffective. This is because the refractory period is set to one hour, so PCA injections within one hour from the most recent PCA injection are considered ineffective. Between 05:00 and 05:59, two PCA injections were performed. The first PCA injection was ineffective, and the second PCA injection was effective. Also, between 15:00 and 15:59, and between 16:00 and 16:59, one effective PCA injection was performed respectively. Marks indicating effective and ineffective PCA injections can be displayed so that they can be distinguished by changing colors, patterns, shapes, etc.

[0040] As described above, the control unit 51 can display the number of effective times when the administration of the drug additionally administered (PCA administration) by the patient is effective and the number of ineffective times when the administration is ineffective in chronological order. By displaying the number of PCA administrations on the same time axis as the time axis indicating the dosage, the state of the patient can be grasped more accurately. Also, based on the timing and number of ineffective PCA administrations, the pain level and timing of the patient can be grasped more accurately.

[0041] The control unit 51 can display the number of effective times when the administration of the drug additionally administered by the patient is effective and the number of ineffective times when the administration is ineffective in different display modes. For example, by displaying ineffective PCA injections in a more emphasized manner than effective PCA injections, it is possible to emphasize that the patient is in pain, and it is possible to prompt medical staff to consider implementing rescue administration or setting a continuous dosage.

[0042] FIG. 6 is a diagram showing a third example of the drug dosage display screen 120. On the display screen 120, a pain index (pain level) area 121 is displayed. In the example of FIG. 6, the pain levels every hour in a day from 00:00 to 23:59 are displayed in a five-level display from 1 to 5. The pain level can be estimated using the learning model 58 as shown in FIG. 3.

[0043] As shown in FIG. 6, it can be seen that the pain level rises from "1" to "3" between 03:00 and 03:59, and the pain level reaches "5" between 04:00 and 04:59. By performing effective PCA administration twice between 03:00 and 04:59, the pain level between 05:00 and 05:59 drops to "4", and further by performing effective PCA administration once between 05:00 and 05:59, it can be seen that the pain level between 06:00 and 06:59 drops to "2".

[0044] As described above, the control unit 51 can estimate at least one of the current and future pain indices of the patient based on the acquired administration information, and display the estimated pain indices in time series. Thereby, the state of the patient can be grasped at a glance.

[0045] In addition, the control unit 51 can calculate the predicted blood concentration values of at least one of a plurality of drugs at required intervals, and display the calculated predicted blood concentration values in time series. The blood concentration can be predicted and calculated as the blood concentration of drug B for which additional administration is performed. When displaying the predicted blood concentration values, the displays such as the dosage and the number of PCA administrations may be made lighter so as not to be conspicuous.

[0046] From the timing at which the predicted blood concentration gradually decreases and the pain level, it is possible to predict the time when the patient begins to feel pain. In FIG. 6, although the current time is not illustrated, assume that the current time is between 03:00 and 03:59. The predicted blood concentration value has been gradually decreasing until the current time. Note that the future pain level of the patient can be estimated. Assume that the current pain level has risen to "3" and the pain level is estimated to be "5" between 04:00 and 04:59 in the future. In such a case, the control unit 51 can estimate the time when the patient begins to feel pain based on the transition of the predicted blood concentration value up to the present and the pain level up to the present, and notify the estimated time.

[0047] As a result, even if pain occurs during sleep and the patient himself / herself wants to perform PCA administration, the medical staff who has received the notification can perform rescue administration, or the pump can automatically administer the drug, thereby preventing the patient from waking up due to pain.

[0048] FIG. 7 is a diagram showing a fourth example of the display screen 130 for the drug administration amount. On the display screen 130, the display modes of the display data from the past to the present and the future display data are made different. In FIG. 7, the current time (time zone) from 10:00 to 10:59 is surrounded by a frame 131 and displayed. Also, the future display data after the time 11:00 is displayed transparently. On the other hand, the past display data from 00:00 to 09:59 is not made transparent. In the example of FIG. 7, the administration amount and the cumulative administration amount up to the present can be drawn with a solid line or the like, and the future administration amount and the cumulative administration amount can be drawn with a broken line or not displayed to distinguish them.

[0049] As described above, the control unit 51 can distinguish and display whether the information to be displayed in time series is current information or future information. As a result, it is possible to grasp at a glance where the current administration status is on the graph.

[0050] In FIG. 7, by displaying the level at which the remaining amount of the syringe becomes equal to or less than a predetermined value with a solid line 134, the predicted time when the remaining amount of the syringe becomes equal to or less than the predetermined value is surrounded by a frame 132.

[0051] As described above, the control unit 51 can display the time when the remaining amount of the drug in at least one of the plurality of medical pumps reaches a predetermined value or less. Thereby, the syringe replacement can be planned in advance.

[0052] In FIG. 7, the predicted time when the pain level becomes equal to or higher than a predetermined level (in the example of the figure, the pain level “3”) is surrounded by a frame 133. Thereby, before the patient starts to feel pain, medical staff can adjust the dosage of the drug, which is useful for the pain relief plan. Also, when the predicted time is during the patient's bedtime, measures can be taken to prevent the patient from waking up due to pain at night. In FIG. 7, the current (real-time) pain level may be displayed near the upper left of the display screen 130, and may be highlighted when the pain level is “4” or higher.

[0053] FIG. 8 is a diagram showing a fifth example of the display screen 140 for the drug dosage. On the display screen 140, a rescue administration execution notification screen 141 is displayed. In FIG. 8, the current time is between 05:00 and 05:59. As shown in FIG. 8, a rescue administration is being carried out between 05:00 and 05:59. Thus, when a rescue administration is carried out by medical staff during the refractory period, a notification prompting a review of the continuous dosage is output.

[0054] As described above, the control unit 51 can output a notification regarding continuous administration when medical staff makes an additional administration. As one of the scenarios where a rescue administration is carried out, it is assumed that it is during the refractory period when the PCA injection by the patient becomes invalid. Therefore, by reviewing the continuous dosage and increasing the dosage, the need for PCA injection by the patient may be eliminated, and it may be possible to prevent the situation where the PCA injection becomes invalid.

[0055] FIG. 9 is a diagram showing an example of a processing procedure for drug dosage display by the display device 50. The control unit 51 acquires administration information of a plurality of drugs administered by a plurality of medical pumps (S11), and calculates the dosage of the plurality of drugs based on the acquired administration information (S12). The dosage for each drug can be calculated by {dosage = reference flow rate × unit time}. The control unit 51 calculates the integrated administration amount of the plurality of drugs (S13). The integrated administration amount may be obtained by integrating the dosage for each drug over time. The control unit 51 identifies the number of effective additional administrations and the number of ineffective additional administrations based on the acquired administration information (S14).

[0056] The control unit 51 estimates a pain index (pain level) based on the acquired administration information (S15). The estimation of the pain index is as shown in FIG. 3. The control unit 51 calculates a predicted blood concentration value of the drug (S16), and displays the dosages and integrated administration amounts of the plurality of drugs in a time series and in a comparable manner using a common time axis within one display screen (S17).

[0057] The control unit 51 displays, using the same time axis, the number of effective additional administrations, the number of ineffective additional administrations, the temporal change of the estimated pain index, the temporal change of the predicted blood concentration value, and the timing when the remaining amount of the syringe becomes equal to or less than a predetermined value (S18).

[0058] The control unit 51 determines whether to end the process (S19). If the process is not ended (NO in S19), the processes after step S11 are continued. If the process is to be ended (YES in S19), the process is ended.

[0059] FIG. 10 is a diagram showing an example of a processing procedure for a method of generating the learning model 58. Hereinafter, for convenience of explanation, the main body of the processing will be described as the control unit 51. However, the generation of the learning model 58 may be performed by a learning processing device other than the display device 50. The control unit 51 acquires training data including administration information (time-series data) of drugs administered to a plurality of patients and pain indexes at required time points (present or future) of the plurality of patients (S30). The pain index at the required time point can be classified into, for example, any one of pain levels 1 to 5 by annotation. For example, the administration information of drugs over six months for a specific patient and the transition of the pain level of the patient over six months are specified by annotation, and data associating the administration information with the pain level may be collected as training data.

[0060] Based on the acquired training data, the control unit 51 generates (learns) the learning model 58 so as to output the pain index of the patient at the required time point when the administration information of the drug administered to the patient is input (S31), stores the generated learning model 58, and ends the processing.
