Patent Document 2

[0007] In Patent Documents 1 and 2, drug solution data (drug library) containing data for multiple drug solutions is distributed to and stored in each pump. In Patent Documents 1 and 2, in order to keep the drug data up-to-date, the drug solution data in each pump must be updated each time. Such an update process is time-consuming and laborious.

[0008] This disclosure has been made in view of the above-mentioned problems, and its purpose is to provide a system, information processing device, and method that eliminate the need for updating chemical solution data, including data for multiple chemical solutions, in a pump. [Means for solving the problem]

The information processing device obtains a prescription order from an external device, which includes the identification information of the drug solution to be administered to the patient from among a plurality of drug solutions, and a set value for the flow rate or administration rate of the drug solution set for the patient. The information processing device obtains the flow rate threshold or administration rate threshold of the drug solution from the drug solution data. The information processing device transmits the prescription order and the flow rate threshold or administration rate threshold of the drug solution to the pump.

[0010] In accordance with other aspects of this disclosure, the information processing device comprises a processor, a communication interface for communicating with a pump capable of administering a drug solution to a patient, and a memory storing drug solution data in which a flow rate threshold or administration rate threshold is associated with the identification information of each of a plurality of drug solutions. The flow rate threshold includes at least one of an upper limit and a lower limit of the flow rate. The administration rate threshold includes at least one of an upper limit and a lower limit of the administration rate. The processor obtains a prescription order from an external device, which includes the identification information of the drug solution to be administered to the patient from among a plurality of drug solutions, and a set value for the flow rate or administration rate of the drug solution set for the patient. The processor obtains the flow rate threshold or administration rate threshold of the drug solution from the drug solution data. The processor transmits the prescription order and the flow rate threshold or administration rate threshold of the drug solution to the pump via the communication interface.

[Effects of the Invention]

Embodiments for Carrying Out the Invention

[0014] Hereinafter, each embodiment of the present disclosure will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated. Also, in the embodiments described below, when referring to the number, amount, etc., unless otherwise specified, the scope of the present invention is not necessarily limited to the number, amount, etc.

[0015] <A. System Configuration> FIG. 1 is a diagram showing the schematic configuration of the network system 1 of the present embodiment.

[0016] As shown in FIG. 1, the network system 1 includes a terminal device 10, a server 20 that records electronic medical records, a server 30 of a pharmacy department, a server 40 of a department different from the pharmacy department, and a communication system 2. The communication system 2 includes a server 50 and a rack system 3. The rack system 3 has a terminal device (information processing device) 60, a plurality of infusion pumps 70A and 70B, and a plurality of syringe pumps 70C, 70D, and 70E. The rack system 3 is operated by a nurse 9 or a doctor.

[0017] The terminal device 10 is typically communicably connected to the server 20 by wire. The server 20 is typically communicably connected to the terminal device 10 and the server 30 by wire. The server 30 is typically communicably connected to the server 20 and the server 50 by wire.

[0018] The server 50 is typically communicably connected to the server 30 and the server 40 by wire. The server 50 is typically further communicably connected to the terminal device 60 of the rack system 3 by wireless.

[0019] The terminal device 10 is typically used by a doctor. The terminal device 10 receives, for each patient, an input of information regarding one or more drugs prescribed to the patient. Hereinafter, the information (information regarding one or more prescribed drugs) input for one patient using the terminal device 10 is also referred to as "prescription list data" for convenience. That is, the terminal device 10 receives an input of prescription list data for each patient. The terminal device 10 transmits the input prescription list data to the server 20. The specific configuration of the prescription list data will be described later (FIG. 4).

[0020] The server 20 receives the prescription list data from the terminal device 10. The server 20 records the content of the received prescription list data in the patient's electronic medical record.

[0021] Server 30 has drug library data (drug solution data) stored in advance. Server 30 sends drug library data to Server 50. When the drug library is updated in Server 30, Server 30 sends update data to Server 50 to update Server 50's drug library. As update data, Server 30 may send the updated drug library data itself, or it may send only the data of the updated parts.

[0022] Server 30 retrieves prescription list data for a designated patient from Server 20 based on input from a pharmacist or other user. Server 30 then transmits prescription list data for a patient who is about to begin treatment (hereinafter also referred to as the "target patient") to Server 50.

[0023] Through the above process, server 50 stores the prescription list data for the target patient and the latest drug library data. Server 50 also retrieves various other data from server 40. For example, server 50 retrieves data related to the target patient's anesthesia from server 40.

[0024] In this example, syringes 90 are set in syringe pumps 70C and 70E. Syringe 90 includes a barrel 91 and a plunger rod 92. The plunger rod 92 has a flange 921. Syringe pumps 70C, 70D, and 70E are equipped with a drive unit 74 having a pressing surface 741. Each of the infusion pumps 70A and 70B and syringe pumps 70C, 70D, and 70E has displays 772 and 773.

[0025] Figure 2 is a diagram illustrating the communication overview in communication system 2 shown in Figure 1.

[0026] As shown in Figure 2, in this example, the server 50 communicates with the terminal device 60 wirelessly. Typically, the server 50 communicates with the terminal device 60 via a wireless LAN (Local Area Network).

[0027] In this example, terminal device 60 communicates wirelessly with infusion pumps 70A and 70B and syringe pumps 70C, 70D, and 70E. More specifically, terminal device 60 communicates with infusion pumps 70A and 70B and syringe pumps 70C, 70D, and 70E via wireless LAN or NFC (Near Field Communication). In the following, any one of the infusion pumps 70A and 70B and syringe pumps 70C, 70D, and 70E (medical pump) will also be referred to as "pump 70".

[0028] Server 50 transmits the drug library data and the target patient's prescription list data, respectively, acquired from Server 20, to Terminal Device 60. As a result, the drug library data and the target patient's prescription list data are stored in Terminal Device 60 of Rack System 3.

[0029] When the drug library data on server 50 is updated, the drug library data on terminal device 60 is also updated. As a result, the same drug library data is stored on server 20 (Figure 1), server 50, and terminal device 60. The drug library data on server 20 is the master data.

[0030] Similarly, the same drug library data is shared between server 30 (Figure 1), server 50, and terminal device 60. The same drug library data is also shared between server 40 (Figure 1), server 50, and terminal device 60.

[0031] <B.データ> Figure 3 shows the schematic structure of the drug library data shown in Figure 1.

[0032] As shown in Figure 3, the drug library data D3 stores at least the flow rate (mL / h) threshold, the dose threshold (mL) threshold, and the administration rate threshold (μg / kg / min), all associated with the drug identification information. The dose is also referred to as the "planned dose."

[0033] Drug identification information includes, for example, the drug number and drug name (drug solution name). Flow rate thresholds include the upper and lower limits of the flow rate. Dosage thresholds include the upper and lower limits of the dosage. Administration rate thresholds include the upper and lower limits of the administration rate. Note that drug library data D3 does not necessarily need to store all of the upper and lower limits for each drug solution.

[0034] As described above, this drug library data D3 is stored in server 20, server 50, and terminal device 60. As described above, when the drug library data D3 in server 20 is updated, the drug library data D3 in server 50 and the drug library data D3 in terminal device 60 are also updated.

[0035] Similarly, the same drug library data is shared between server 30, server 50, and terminal device 60. The same drug library data is also shared between server 40, server 50, and terminal device 60.

[0036] Figure 4 is a diagram showing the schematic structure of the prescription list data shown in Figure 1.

[0037] As shown in Figure 4, prescription list data D41 includes a patient ID to identify the patient and one or more prescription orders #1, #2, #3…

[0038] In this example, each prescription order #1, #2, #3, etc. includes drug identification information, a flow rate setting, and a dosage setting. The flow rate setting and dosage setting are values ​​specified by the physician. These settings are values ​​entered in terminal device 10. Each prescription order #1, #2, #3, etc. may also include a setting for the administration rate.

[0039] Examples of prescription orders include "administer 500 mL of physiological saline at 20 mL / h". In this case, the prescription order includes "physiological saline" as the drug identification information, "20 mL / h" as the set value of the flow rate, and "500 mL" as the set value of the dosage.

[0040] The pharmacy department checks whether each of the set value of the flow rate (or the set value of the administration rate) and the set value of the dosage is within a predetermined range. If the set value is inappropriate, the pharmacy department asks the responsible doctor (the doctor who created the prescription list data) to confirm the numerical value and urges the responsible doctor to correct the set value. Therefore, the set value of the flow rate (or the set value of the administration rate) and the set value of the dosage transmitted to the server 50 and the terminal device 60 are usually within the above-mentioned predetermined range. Note that the network system 1 (for example, the server 30 or the server 40) may automatically determine the above check.

[0041] Specifically, the above-mentioned predetermined range is defined by at least one of a lower limit value and an upper limit value. In the drug library data D3 (see FIG. 3), such upper limit values and lower limit values are recorded for each drug solution.

[0042] <C. Device Configuration> The specific configurations of the server 50, the terminal device 60, and the pump 70 that constitute the communication system 2 (see FIG. 1) will be described.

[0043] (c1. Server) FIG. 5 is a diagram showing an example of the hardware configuration of the server 50.

[0044] As shown in FIG. 5, the server 50 includes a control unit 51, a communication IF (Interface) 52, and a clock 53. The control unit 51 includes a processor 511 and a memory 512. The processor 511, the memory 512, the communication IF 52, and the clock 53 are typically attached to a motherboard (not shown).

[0045] Memory 512 consists of storage media such as RAM (Random Access Memory), ROM (Read Only Memory), SSD (Solid State Drive), and HDD (Hard Disk Drive). Memory 512 stores prescription list data D41, D42, D43, D44, etc., created for each target patient.

[0046] Prescription list data D41 is the data for patient ID "0001". Similarly, prescription list data D42 is the data for patient ID "0002", for example. Prescription list data D43 is the data for patient ID "0003", for example.

[0047] Communication IF52 is an interface for communication between servers 30, 40 and terminal device 60. Through communication IF52, server 50 can acquire drug library data D3, prescription list data D41, etc.

[0048] Clock 53 measures the time. The measured time information is sent to control unit 51.

[0049] The control unit 51 controls the overall operation of the server 50. Specifically, the processor 511 executes an operating system (not shown) and various application programs (not shown) stored in the memory 512, thereby enabling the server 50 to perform various operations.

[0050] (c2. Terminal device) Figure 6 shows an example of the hardware configuration of the terminal device 60.

[0051] As shown in Figure 6, the terminal device 60 comprises a control unit 61, a touchscreen 62, a communication interface 63, and a clock 64. The control unit 61 includes a processor 611 and memory 612. The touchscreen 62 includes a touch panel 621 and a display 622. The touch panel 621 is mounted on the display 622. The processor 611, memory 612, communication interface 63, and clock 64 are typically mounted on a motherboard (not shown).

[0052] Memory 612 consists of storage media such as RAM, ROM, and flash memory. Memory 612 stores prescription list data D43 for one target patient (in this example, the patient with patient ID "0003"). Specifically, because Nurse 9 performed an operation on terminal device 60 to retrieve prescription list data D43 for patient with patient ID "0003" from server 50, prescription list data D43 is stored in memory 612 of terminal device 60.

[0053] The terminal device 60 does not need to acquire the prescription list data D43 itself; it may acquire prescription order #1 and prescription order #2 separately, associated with the patient ID. At a minimum, the terminal device 60 only needs to be able to acquire prescription order #1 and prescription order #2 from the server 50. There are no particular limitations on the user operations during acquisition. In the following explanation, we will use the case where the terminal device 60 acquires prescription order #1 and prescription order #2 individually as an example.

[0054] Communication IF63 is an interface for communication between the server 50 and multiple pumps 70. Through communication IF63, the terminal device 60 can obtain drug library data D3 and prescription list data D43.

[0055] The clock 64 measures the time. The measured time information is sent to the control unit 61.

[0056] The touchscreen 62 accepts user input and displays various information. The display 622 displays various screens based on the output from the processor 611. When the touch panel 621 receives user input (typically a touch operation by a nurse 9) while the screen is displayed, it sends a signal based on that input to the processor 611.

[0057] The control unit 61 controls the overall operation of the terminal device 60. Specifically, the processor 611 executes an operating system (not shown) and various application programs (not shown) stored in the memory 612, thereby causing the terminal device 60 to perform various operations.

[0058] (c3. Pump) Figure 7 shows an example of the hardware configuration of the pump 70.

[0059] As shown in Figure 7, the system comprises a control unit 71, a communication interface 72, a clock 73, a drive unit 74, a speaker 75, an alarm lamp 76, and an operation panel 77. The control unit 71 includes a processor 711 and a memory 712. The operation panel 77 includes operation buttons 771 and displays 772 and 773. The processor 711, memory 712, communication interface 72, and clock 73 are typically mounted on a motherboard (not shown).

[0060] Memory 712 is composed of storage media such as RAM, ROM, and flash memory. Memory 712 stores prescription order #1 (see Figure 6) included in the prescription list data D43 for one target patient (in this example, the patient with patient ID "0003"). Specifically, because Nurse 9 performed the operation of sending prescription order #1 from prescription list data D43 to pump 70 using terminal device 60, prescription order #1 from prescription list data D43 is stored in the memory 712 of pump 70.

[0061] Furthermore, memory 712 stores the flow rate threshold and the dosage threshold of the drug solution (hereinafter also referred to as "administered drug solution") described in prescription order #1 of prescription list data D43. As mentioned above, one prescription order contains information for one drug solution.

[0062] In more detail, based on the operation performed by Nurse 9 on the terminal device 60 to send prescription order #1 of prescription list data D43 to the pump 70, the threshold values ​​for the flow rate and the dose of the administered drug described in prescription order #1 are transmitted from the terminal device 60 to the pump 70 and stored in memory 712.

[0063] The control unit 71 controls the overall operation of the pump 70. Specifically, the processor 711 executes an operating system (not shown) and various application programs (not shown) stored in the memory 712, causing the pump 70 to perform various operations.

[0064] Communication IF72 is an interface for communicating with the terminal device 60. Through communication IF72, the pump 70 can obtain prescription order #1, the flow rate threshold, and the dosage threshold.

[0065] Clock 73 measures the time. The measured time information is sent to control unit 71.

[0066] The drive unit 74 is a mechanism for administering the drug solution set in the pump 70 to the patient. The drive unit 74 operates according to commands from the control unit 71. If the pump 70 is a syringe pump, the drive unit 74 is a mechanism for moving the plunger rod 92 of the syringe 90 (see Figure 1) within the barrel 91 of the syringe 90. Specifically, the drive unit 74 moves the plunger rod 92 toward the barrel 91 by pressing the flange 921 with the pressing surface 741. This allows the drug solution to be administered to the patient.

[0067] The speaker 75 performs a predetermined notification (voice notification) according to a command from the control unit 71.

[0068] The alarm lamp 76 performs a predetermined notification (notification by light emission) according to a command from the control unit 71. The alarm lamp 76 is also referred to as an indicator.

[0069] The operation panel 77 receives operations by the nurse 9 and performs various displays. Specifically, the operation button 771 receives operations by the nurse 9. The operation button 771 typically includes a plurality of operation buttons. An instruction corresponding to the received operation content is sent from the operation panel 77 to the control unit 71.

[0070] The displays 772, 773 (see FIG. 1) display various screens based on the output from the processor 711. For example, the administration rate and the like are displayed on the display 772. Information such as the flow rate and the like is displayed on the display 773.

[0071] <D. Flow of processing> Hereinafter, for convenience of explanation, the prescription list data D43 of the patient with patient ID "0003" will be described. Also, for convenience of explanation, among the five pumps 70, the infusion pumps 70A and 70B will be described. The prescription list data D43 and the infusion pumps 70A, 70B are examples and are not limited thereto.

[0072] Also, in the following example, from the viewpoint of simplifying the explanation, among the flow rate threshold value, the administration amount threshold value, and the administration rate threshold value shown in FIG. 3, the flow rate threshold value will be described. Note that the terminal device 60 can also execute the same processing for the lower limit value of the flow rate, the administration amount threshold value, and the administration rate threshold value.

[0073] FIG. 8 is a sequence diagram for explaining the flow of processing executed in the communication system 2.

[0074] As shown in Figure 8, in sequence SQ1, server 50 transmits prescription order #1, which is included in prescription list data D43, to terminal device 60. Prescription order #1 includes, as described above, at least drug identification information and flow rate setting values ​​(values ​​set by the physician).

[0075] In sequence SQ2, terminal device 60 reads the threshold flow rate of drug solution #1, as described in the received prescription order #1, from memory 612. Specifically, terminal device 60 reads the threshold flow rate of drug solution #1 from the drug library data D3 (see Figure 6) stored in memory 612.

[0076] In sequence SQ3, terminal device 60 associates prescription order #1 with infusion pump 70A based on the input operation of nurse 9. That is, terminal device 60 links prescription order #1 with infusion pump 70A. In sequence SQ4, terminal device 60 transmits prescription order #1 and the flow rate threshold of drug solution #1 to infusion pump 70A associated with prescription order #1, based on the input operation of nurse 9.

[0077] Based on the above, prescription order #1 and the flow rate threshold for drug solution #1 specified in prescription order #1 are set in the infusion pump 70A. Unless the flow rate setting for drug solution #1 is changed by nurse 9 or the like, the infusion pump 70A will start administering drug solution #1 to the patient based on the flow rate setting when the start button is pressed.

[0078] In sequence SQ5, server 50 transmits prescription order #2, which is included in prescription list data D43, to terminal device 60. Prescription order #2 includes at least drug identification information and flow rate settings, as described above.

[0079] In sequence SQ6, terminal device 60 reads the threshold flow rate of drug solution #2, as described in the received prescription order #2, from memory 612. Specifically, terminal device 60 reads the threshold flow rate of drug solution #2 from drug library data D3 stored in memory 612.

[0080] In sequence SQ7, terminal device 60 associates prescription order #2 with infusion pump 70B based on the input operation of nurse 9. That is, terminal device 60 links prescription order #2 with infusion pump 70B. In sequence SQ8, terminal device 60 transmits prescription order #2 and the flow rate threshold of drug solution #2 to infusion pump 70B associated with prescription order #2, based on the input operation of nurse 9.

[0081] Based on the above, prescription order #2 and the flow rate threshold for drug solution #2 specified in prescription order #2 are set in the infusion pump 70B. Unless the flow rate setting for drug solution #2 is changed by nurse 9 or the like, the infusion pump 70B will start administering drug solution #2 to the patient based on the flow rate setting for drug solution #2, triggered by pressing the start button.

[0082] In summary, the rack system 3 is as follows: The rack system 3 comprises a pump 70 (for example, an infusion pump 70A) capable of administering drug solutions to a patient, and a terminal device 60 that can communicate with the pump 70 and stores drug library data D3 in which a flow rate threshold is associated with the identification information (typically, the name) of each of the multiple drug solutions.

[0083] The terminal device 60 obtains a prescription order (e.g., prescription order #1) from the server 50, which is an external device of the rack system 3, which includes identification information of the drug solution to be administered to a patient (e.g., patient with patient ID "0003") from among the multiple drug solutions (e.g., drug solution #1) and the set value of the flow rate of the drug solution set for the patient. The terminal device 60 obtains the threshold value of the flow rate of the drug solution from the drug library data D3 (specifically, reads the threshold value). The terminal device 60 transmits the prescription order and the threshold value of the flow rate of the drug solution to the pump 70.

[0084] With this configuration, it becomes unnecessary to send the drug library data D3 to each pump 70. Therefore, the drug solution data update process in each pump 70 is eliminated. Furthermore, each pump 70 can obtain not only the prescription order but also the threshold flow rate of the drug solution to be administered to the pump 70.

[0085] Figure 9 is a flowchart illustrating the processing flow in infusion pump 70A with drug solution #1 set inside.

[0086] As shown in Figure 9, in step S1, the infusion pump 70A determines whether or not it has received an input operation to change the flow rate of drug solution #1. If the infusion pump 70A determines that it has received the input operation (YES in step S1), in step S2 it determines whether or not the input flow rate value (new setting value) is within the range of the flow rate of drug solution #1 that is less than or equal to the upper limit and greater than or equal to the lower limit (the "predetermined range" mentioned above). If the infusion pump 70A determines that it has not received the input operation (NO in step S1), it returns to step S1.

[0087] If the infusion pump 70A determines that the input flow rate value is within the above range (YES in step S2), in step S3, it permits a change in flow rate and changes the flow rate to the input value. If the infusion pump 70A determines that the input flow rate value is outside the above range (NO in step S2), in step S4, it does not permit a change in flow rate and displays a warning. The warning is displayed, for example, on display 772 or display 773. The infusion pump 70A may be configured to emit an alarm sound along with or instead of a warning display.

[0088] Thus, the infusion pump 70A accepts changes to the flow rate setting of drug solution #1, as long as it does not exceed the upper limit of the flow rate of drug solution #1. Therefore, it is possible to prevent the setting from being changed in a way that exceeds the upper limit. Furthermore, the infusion pump 70A accepts changes to the flow rate setting of drug solution #1, as long as it does not fall below the lower limit of the flow rate of drug solution #1. Therefore, it is possible to prevent the setting from being changed in a way that falls below the lower limit. Note that the same effect can be obtained in the infusion pump 70B and syringe pumps 70C, 70D, and 70E by performing the same series of processes as described above.

[0089] Figure 10 is a sequence diagram illustrating the process of updating drug library data D3.

[0090] As shown in Figure 10, in sequence SQ11, the pharmacy department's server 30 (see Figure 1) executes the update process for drug library data D3. In sequence SQ12, server 30 sends update data for updating drug library data D3 to server 50 of communication system 2. In sequence SQ13, server 50 updates the drug library data D3 stored in memory 512 (see Figure 5) using the update data.

[0091] In sequence SQ14, server 50 transmits update data for updating drug library data D3 to terminal device 60 of rack system 3. In sequence SQ15, terminal device 60 uses the update data to update drug library data D3 stored in memory 612 (see Figure 6).

[0092] Thus, when the drug library data D3 is updated in the servers 30 and 50, the terminal device 60 acquires data for updating the updated drug library data D3 from the server 50. Thereby, the terminal device 60 updates the drug library data D3 in the terminal device 60. According to such a configuration, the servers 30 and 50 and the terminal device 60 constituting the network system 1 can possess (share) the latest drug library data D3.

[0093] <E. Modified Example> In FIGS. 8 and 9, the case of transmitting the upper limit value and the lower limit value of the flow rate to the pump 70 has been described as an example. However, the terminal device 60 may be configured to transmit only one of the upper limit value and the lower limit value.

[0094] Also, in FIGS. 8 and 9, the case of transmitting only the flow rate threshold value among the three types of threshold values, i.e., the "flow rate threshold value", the "dosage threshold value", and the "administration rate threshold value", to the pump 70 has been described as an example. However, the present invention is not limited to this. It is sufficient that the terminal device 60 transmits at least one of the three types of threshold values to the pump 70. For example, the terminal device 60 may be configured to transmit the flow rate threshold value and the dosage threshold value to the pump 70.

[0095] Similar to the flow rate threshold value, the terminal device 60 may be configured to transmit at least one of the upper limit value and the lower limit value of the dosage threshold value to the pump 70. Similarly, the terminal device 60 may be configured to transmit at least one of the upper limit value and the lower limit value of the administration rate threshold value to the pump 70.

[0096] When transmitting dosage thresholds, the rack system 3 can be said to have the following configuration. The rack system 3 comprises a pump 70 (e.g., infusion pump 70A) capable of administering drug solutions to a patient, and a terminal device 60 that can communicate with the pump 70 and stores drug library data D3 in which dosage thresholds are associated with the identification information of each of the multiple drug solutions. The dosage threshold includes at least one of the upper limit and lower limit of the dosage. The terminal device 60 obtains a prescription order (e.g., prescription order #1) from the server 50, which is an external device of the rack system 3, which includes the identification information of the drug solution to be administered to a patient (e.g., a patient with patient ID "0003") from among the multiple drug solutions (e.g., drug solution #1) and the set value of the dosage of the drug solution set for the patient. The terminal device 60 obtains the dosage threshold of the drug solution from the drug library data D3 (specifically, reads the threshold). The terminal device 60 transmits a prescription order and a threshold value for the dosage of the administered drug solution to the pump 70.

[0097] With this configuration, each pump 70 can obtain not only prescription orders but also threshold values ​​for the dosage of the drug solution to be administered to the pump 70.

[0098] When transmitting a threshold for the administration rate, the rack system 3 can be said to have the following configuration. The rack system 3 comprises a pump 70 (e.g., infusion pump 70A) capable of administering drug solutions to a patient, and a terminal device 60 that can communicate with the pump 70 and stores drug library data D3 in which an administration rate threshold is associated with the identification information of each of the multiple drug solutions. The administration rate threshold includes at least one of the upper limit of the administration rate and the lower limit of the dose. The terminal device 60 obtains a prescription order (e.g., prescription order #1) from the server 50, which is an external device of the rack system 3, which includes the identification information of the drug solution to be administered to a patient (e.g., a patient with patient ID "0003") from among the multiple drug solutions (e.g., drug solution #1) and the set value of the administration rate of the drug solution set for the patient. The terminal device 60 obtains the threshold for the administration rate of the drug solution from the drug library data D3 (specifically, reads the threshold). The terminal device 60 transmits a prescription order and a threshold value for the administration rate of the drug solution to the pump 70.

[0099] With this configuration, each pump 70 can obtain not only prescription orders but also threshold values ​​for the administration rate of the drug solution set in the pump 70.
