Below, one embodiment of the present disclosure will be described with reference to the drawings. In each drawing, parts having the same configuration or function are given the same reference numerals. In the description of this embodiment, duplicate descriptions of the same parts may be omitted or simplified as appropriate.

(Chemical solution administration system)
1 is a diagram showing a configuration of a medicinal liquid administration system 1 according to one embodiment. The medicinal liquid administration system 1 includes a smartphone 10 as an information processing device according to this embodiment, and a syringe pump 20 as a medical device according to this embodiment. The smartphone 10 and the syringe pump 20 are configured to be able to communicate information with each other by wire or wirelessly. The smartphone 10 is an information processing device for setting the setting values of the syringe pump 20. The syringe pump 20 is a device that delivers an infusion into the body of a patient P according to setting values such as a flow rate and a dosage amount set by the smartphone 10.

In the drug solution administration system 1 according to this embodiment, the user operates the smartphone 10 to input a setting value for the syringe pump 20. Specifically, the smartphone 10 accepts the selection of the most significant digit from the user, and then displays the selected numerical values in the area of the digits below the most significant digit in order according to the numerical value selection, thereby accepting the input of the setting value from the user. In response to the input of the setting value, the smartphone 10 transmits the setting value to the syringe pump 20. The syringe pump 20 controls its operation based on the setting value received from the smartphone 10. Therefore, according to the configuration according to this embodiment, it is possible to prevent the input of a numerical value beyond the most significant digit, and it is possible to more effectively prevent erroneous operation without impairing the operability of the user.

In this embodiment, the smartphone 10 is used as an example of an information processing device capable of communicating with the syringe pump 20. However, other electronic devices such as a tablet, a PC (Personal Computer), or a wearable device may be used instead of the smartphone. In this embodiment, the syringe pump 20 is used as an example of a medical device that operates based on a set value. However, in place of the syringe pump, various medical pumps including general infusion pumps, insulin pumps, and PCA pumps, as well as nutrition pumps and blood pumps, and other medical devices may be used. Here, a general infusion pump is, for example, a pump that does not include an infusion cartridge and that delivers the infusion in the infusion bag by pressing an infusion tube connected to an infusion bag outside the pump.

(Smartphone)
Fig. 2 is a diagram showing an example of the configuration of the smartphone 10 in Fig. 1. The smartphone 10 includes a control unit 11, a storage unit 12, a communication unit 13, an input unit 14, and an output unit 15.

The control unit 11 is one or more processors. The processor is a general-purpose processor such as a CPU or a GPU (Graphics Processing Unit), or a dedicated processor specialized for a specific process. The control unit 11 may include one or more dedicated circuits, or the one or more processors in the control unit 11 may be replaced with one or more dedicated circuits. The dedicated circuits are, for example, FPGAs or ASICs. The control unit 11 controls each part of the smartphone 10 to execute information processing related to the operation of the smartphone 10.

The memory unit 12 is one or more semiconductor memories, one or more magnetic memories, one or more optical memories, or a combination of at least two of these. The semiconductor memory is, for example, a RAM or a ROM. The RAM is, for example, a Static RAM (SRAM) or a Dynamic RAM (DRAM). The ROM is, for example, an Electrically Erasable Programmable ROM (EEPROM). The memory unit 12 functions, for example, as a main memory device, an auxiliary memory device, or a cache memory. The memory unit 12 stores, for example, setting values to be set in the syringe pump 20 input by a user operation.

The communication unit 13 is a communication interface for communicating with the syringe pump 20. The communication unit 13 communicates with the syringe pump 20 and transmits setting values, such as flow rate and dosage, input by the user to the syringe pump 20. The communication unit 13 communicates with the syringe pump 20, for example, via Bluetooth (registered trademark), but is not limited to this, and may communicate, for example, via other wireless communication paths such as a wireless LAN (Local Area Network) or a wired cable. The communication unit 13 may also communicate with the syringe pump 20 via other devices, including a server or cloud, along the way.

The input unit 14 includes one or more input interfaces that accept input operations by the user and acquire input information based on the user operations. The input unit 14 is, for example, a touch screen that is integral with the display of the output unit 15, but is not limited thereto and may be physical keys (for example, an external numeric keypad), capacitance keys, a pointing device, or a microphone that accepts voice input.

The output unit 15 as a display unit includes one or more output interfaces that output information to the user and notify the user. For example, the output unit 15 is a display that outputs information by displaying an image, but is not limited to this.

The functions of the smartphone 10 are realized by executing a program (computer program) according to this embodiment on a processor included in the control unit 11. That is, the functions of the smartphone 10 are realized by software. The program causes a computer to execute processing of steps included in the operation of the smartphone 10, thereby causing the computer to realize a function corresponding to the processing of those steps. That is, the program is a program for causing an information processing device to function as the smartphone 10 according to this embodiment.

The program may be recorded on a computer-readable recording medium. The computer-readable recording medium may be, for example, a magnetic recording device, an optical disk, a magneto-optical recording medium, or a semiconductor memory. The program may be distributed, for example, by selling, transferring, or lending a portable recording medium on which the program is recorded, such as a Universal Serial Bus (USB) memory, a Blu-ray (registered trademark) Disc, a Digital Versatile Disc ROM (DVD-ROM), or a Compact Disc ROM (CD-ROM). The program may be distributed by being stored in the storage of a server and transferred from the server to other computers via a network. The program may be provided as a program product.

The computer temporarily stores in the main storage device, for example, a program recorded on a portable recording medium or a program transferred from a server. The computer then reads the program stored in the main storage device with a processor and executes processing according to the read program with the processor. The computer may read the program directly from the portable recording medium and execute processing according to the program. The computer may execute processing according to the received program each time a program is transferred to the computer from the server. Processing may be executed by a so-called ASP (Application Service Provider) type service that does not transfer a program from the server to the computer and achieves functions only by issuing execution instructions and obtaining results. Programs include information used for processing by a computer that is equivalent to a program. For example, data that is not a direct command to a computer but has properties that define computer processing falls under "something equivalent to a program."

Some or all of the functions of the smartphone 10 may be realized by a dedicated circuit included in the control unit 11. In other words, some or all of the functions of the smartphone 10 may be realized by hardware. In addition, the smartphone 10 may be realized by a single information processing device, or may be realized by the cooperation of multiple information processing devices.

(Syringe pump)
Fig. 3 is a diagram showing an example of the external configuration of the syringe pump 20 in Fig. 1. As shown in Fig. 3, the syringe pump 20 includes a syringe pump body 21 and a syringe 22 that can be attached to the syringe pump body 21. The syringe 22 is attached to the syringe pump body 21 after an infusion liquid such as a medicinal liquid is previously contained in a barrel 222. The syringe pump body 21 pushes a plunger 221 of the syringe 22 by a plunger drive unit 215, thereby sending the infusion liquid in the barrel 222 into the body of the patient P via a tube 223.

The syringe pump body 21 includes a control unit 211, a display unit 212, an operation panel unit 213, a plunger drive unit 215, a support unit 216, a clamp unit 217, and a flange receiving groove 218. The syringe 22 includes a plunger 221, a barrel 222, a tube 223, and an indwelling needle 224.

The control unit 211 is one or more processors. The processor controls each part of the syringe pump body 21 to execute processing related to the operation of the syringe pump 20. For example, the control unit 211 controls the driving of the plunger drive unit 215 based on a set value such as the infusion flow rate or dosage amount input by a user operation. The control unit 211 is a dedicated processor specialized for the processing of the syringe pump body 21, but may be configured with a general-purpose processor such as a CPU or a GPU (Graphics Processing Unit). The dedicated circuit is, for example, an FPGA or ASIC. The control unit 211 has a communication interface for communicating with the smartphone 10, for example, via Bluetooth (registered trademark) or the like.

The display unit 212 is a display. The display unit 212 outputs information related to the operating state of the syringe pump 20 by displaying an image. The display unit 212 may be configured, for example, as a liquid crystal display device.

The operation panel unit 213 includes one or more input interfaces that accept input operations from a user and acquire input information based on the user's operations. In the example of FIG. 3, the operation panel unit 213 includes a plurality of buttons, but in addition to this, or instead of this, for example, the operation panel unit 213 may be a touch screen that is provided integrally with the display of the display unit 212.

The plunger drive unit 215 drives the plunger 221 of the syringe 22 in the tip direction toward the tip side of the barrel 222. With the barrel 222 of the syringe 22 fixed to the syringe pump body 21, the plunger drive unit 215 drives the plunger 221 by pressing the plunger 221 toward the tip side of the barrel 222. As the plunger 221 is driven in the tip direction toward the tip side of the barrel 222, the infusion contained in the barrel 222 is sent out to the tube 223 side.

The support portion 216 supports the syringe 22 attached to the syringe pump body 21. The clamp portion 217 fixes the barrel 222 of the syringe 22 supported by the support portion 216 by sandwiching it between the support portion 216 and the clamp portion 217. When the syringe 22 is attached to the syringe pump body 21, the flange portion of the syringe 22 fits into the flange receiving groove 218 to fix the barrel 222.

The plunger 221 of the syringe 22 can move in the longitudinal direction of the syringe pump body 21 relative to the barrel 222. The barrel 222 contains the infusion liquid. When the plunger 221 is pressed toward the tip of the barrel 222 by driving the plunger drive unit 215, the infusion liquid is pushed out through the tube 223, and is delivered into the body of the patient P via the indwelling needle 224 provided at the distal end of the tube 223.

(Numeric value setting process)
In the drug solution administration system 1 according to the present embodiment, the smartphone 10 receives input of a setting value such as a flow rate or a dosage amount of the syringe pump 20, and the smartphone 10 transmits the setting value to the syringe pump 20, thereby setting the setting value in the syringe pump 20. Figures 4A to 4D are diagrams showing an example of an image 40 (40a, 40b, 40c, 40d) displayed on the output unit 15 of the smartphone 10 in Figure 2 when receiving an input of a setting value.

The image 40 (40a, 40b, 40c, 40d) displayed on the smartphone 10 includes a display area 41 (41a, 41b, 41c, 41d) and a numeric selection area 42. The display area 41 (41a, 41b, 41c, 41d) is an area capable of displaying a number of multiple digits. Figures 4A to 4D show examples of the display area 41 (41a, 41b, 41c, 41d) capable of displaying a total of six digits, including five digits after the decimal point and one digit below the decimal point. The numeric selection area 42 is an area in which the user can select a desired number from among multiple numbers. Figures 4A to 4D show an example of the numeric selection area 42 in the form of a numeric keypad that allows the user to select one of ten numbers from "0" to "9". Below, an example is described in which a setting value is input and displayed in decimal format via the display area 41 (41a, 41b, 41c, 41d) and the numeric selection area 42, but the numeric format for input and display may be other formats such as octal or hexadecimal. Below, an example is described in which a user selects a numeric value by operating the numeric selection area 42 displayed on the output unit 15, but the smartphone 10 may accept a numeric selection from a device such as an external numeric keypad as a numeric input unit.

Image 40a in FIG. 4A shows an image displayed on the initial screen when inputting a setting value. In the example of FIG. 4A, 0 is displayed as the initial value in each digit of display area 41a, but instead, smartphone 10 may display uninputted digits as blanks or a specific symbol (e.g., an asterisk (*)).

The smartphone 10 displays an image as shown in FIG. 4A and accepts the selection of the most significant digit in the display area 41a from the user. For example, the smartphone 10 accepts the selection of the most significant digit by a touch operation on any digit of the display area 41a displayed on the output unit 15. In response to the user selecting the most significant digit, the smartphone 10 causes the output unit 15 to display a cursor on the most significant digit of the display area 41a. FIG. 4B shows an example in which a cursor 43b is displayed in response to the selection of the thousands digit in the display area 41a. The cursor 43b is a display indicating a digit into which a numerical value can be input by selecting a numerical value in the numerical value selection area 42. FIGS. 4B to 4D show an example in which the cursor 43 (43b, 43c) is displayed by highlighting the edge of the display area of the digits that can be input in the display area 41 (41b, 41c, 41d), but the display of the cursor 43 is not limited to this as long as the digits that can be input can be identified. For example, the smartphone 10 may display the cursor 43 in the display area 41 by displaying the digits that can be entered in a background color different from the other digits, or by displaying a blinking symbol on the digits that can be entered.

In response to the user selecting a number via the number selection area 42, the smartphone 10 displays the selected number in the digit where the cursor 43 is displayed on the output unit 15, and moves the cursor 43 to the lower digit by one digit. For example, in the state shown in FIG. 4B, when the user selects the number "1" via the number selection area 42, the smartphone 10 displays "1" in the thousands digit of the display area 41 and moves the cursor 43 from the thousands digit to the hundreds digit. Next, for example, when the user selects the number "2" via the number selection area 42, the smartphone 10 displays "2" in the hundreds digit of the display area 41 and moves the cursor 43 from the hundreds digit to the tens digit. Next, for example, when the user selects the number "3" via the number selection area 42, the smartphone 10 displays "3" in the tens digit of the display area 41 and moves the cursor 43 from the tens digit to the ones digit. Figure 4C shows the state after the user has selected the numbers "1," "2," and "3" in succession in this way.

When the user selects successive numbers in this manner, the smartphone 10 displays the selected numbers in order from the most significant digit to the lowest digit. When the user selects another number while the cursor 43 is displayed in the lowest digit of the display area 41, the smartphone 10 causes the output unit 15 to display the selected number in the digit where the cursor 43 is displayed, and erases the display of the cursor 43. Figure 4D shows a state in which the user has selected the numbers "4" and "5" successively from the state of Figure 4C, so that a number ("5") has been entered in the lowest digit, 0.1, of the example of Figure 4D, and the cursor 43 has been erased.

When the user inputs a setting value, the smartphone 10 stores the input setting value in the memory unit 12. In response to an instruction from the user, the smartphone 10 transmits the setting value stored in the memory unit 12 to the syringe pump 20.

In this way, the smartphone 10 accepts the selection of the most significant digit in the display area 41 from the user, and in response to the selection of a numerical value by the user, the output unit 15 sequentially displays the selected numerical value in the area of the digits below the most significant digit of the display area 41. Therefore, the smartphone 10 prohibits the user from erroneously inputting a numerical value exceeding the most significant digit, and therefore can prevent erroneous operation by the user. In addition, the smartphone 10 accepts numerical input via the numerical value selection area 42 that allows the user to select a desired numerical value from among multiple numerical values, such as a numeric keypad, so that the user can easily input a setting value in a manner similar to operating a calculator. When numerical input is accepted by a touch panel, as in the smartphone 10, it is difficult for the user to distinguish the object being operated (e.g., a button, etc.) by touch or to perform multiple input operations in succession, compared to physical buttons. In addition, due to the size constraints of the output unit 15, it may be difficult to display an interface for performing dedicated up-down operations for each digit of the display area 41. The smartphone 10 according to this embodiment accepts input of a numerical value via a numerical value selection area 42 that allows the user to select a desired numerical value from among multiple numerical values, like a numeric keypad, thereby allowing the user to easily input a setting value even if such a restriction exists.

Note that while Figs. 4A to 4D show examples in which the user inputs a numerical value up to the lowest digit, if the user instructs to end input without inputting up to the lowest digit, the smartphone 10 may set the value of the uninputted digit to, for example, "0". For example, as shown in Fig. 4C, if the numerical values "1", "2", and "3" have been input from the thousands digit onwards and the user instructs to end input, the smartphone 10 may set the value to "1230.0". The smartphone 10 may receive an instruction to end input by, for example, selecting the "Back" button in Fig. 5B, which will be referred to later.

A specific example of an operation for setting a set value in the syringe pump 20 using an input interface as described with reference to Figs. 4A to 4D will be described with reference to Figs. 5A and 5B. Figs. 5A and 5B are diagrams showing an example of an image 50 (50a, 50b) displayed on the output unit 15 of the smartphone 10 in Fig. 2. Figs. 5A and 5B are displayed, for example, by an app for administering medicinal liquids that runs on the smartphone 10.

5A shows an example of an image 50a showing administration contents. In FIG. 5A, the display area 51 displays the name of the drug to be administered to the patient P, the name of the pump, etc. The display area 52 displays the set value of the planned amount of infusion (dosage). The display area 53 displays the set value of the flow rate of the infusion. The smartphone 10 may display, for example, the default value of the set value or the value set at the time of the previous operation in the display area 52 and the display area 53 included in the initial screen of the image 50a showing the administration contents. The display area 54 displays the remaining time of the infusion administration. The display area 55 displays the personal information of the patient P, the administration contents, and comments from the doctor, etc. The button 56 is a button for resetting the set values of the planned amount and the dosage. The button 57 is a button for canceling the setting of the planned amount and the dosage. The button 58 is a button for sending the set values displayed in the display areas 52 and 53 to the syringe pump 20.

When changing the planned amount of infusion (dosage) displayed in display area 52, the user selects display area 52. When changing the flow rate of infusion displayed in display area 53, the user selects display area 53. When the user selects display area 52 or display area 53, smartphone 10 displays a screen for changing the setting value of the selected display area 52 or display area 53.

Figure 5B shows an example of an image 50b displayed on the output unit 15 when the display area 53 of the flow rate in Figure 5A is selected. In the image 50b, the display area 61 is an area in which the set value of the flow rate can be displayed. The numerical value selection area 62 is an area in which the user can select a desired numerical value from the numerical values "0" to "9" in order to change the set value of the flow rate. The smartphone 10 displays a preset set value in the display area 61 and accepts the selection of the most significant digit from the user by a touch operation on any digit of the display area 61. In response to the user selecting the most significant digit, the smartphone 10 displays a cursor on the selected most significant digit. Figure 5B shows a state in which the smartphone 10 displays the set value of the flow rate in the display area 61, and then the user selects the hundreds digit and displays the cursor 63 on the hundreds digit. Following this, when a numerical value is selected in the numerical value selection area 62, the smartphone 10 displays the selected numerical value on the digit on which the cursor 63 is displayed on the output unit 15, and moves the cursor 63 to the lower digit by one digit and displays it. The smartphone 10 repeats this operation until a numerical value is input to the least significant digit. The smartphone 10 may accept a selection from the user of a digit other than the most significant digit of the preset setting value as the most significant digit. For example, if 172.5 mL/h is preset as the setting value of the flow rate, the smartphone 10 may allow the user to select a digit other than the hundreds digit as the most significant digit. After changing the setting value, when the user selects "Back", the smartphone 10 displays on the output unit 15 a screen as shown in FIG. 5A in which the setting value has been updated. Furthermore, when the user selects button 58, the smartphone 10 transmits the changed setting value to the syringe pump 20. Through this operation, the setting value is set in the syringe pump 20.

In the medical solution administration system 1, an example has been described in which a set value is set in the syringe pump 20 via the smartphone 10, but a medical device including the syringe pump 20 may display a screen such as those shown in Figs. 4A to 4D on a display unit to accept input of a set value. Fig. 6 is a diagram showing an example of an image 70 displayed on the display unit 212 of the syringe pump 20 in Fig. 3.

6, the display area 71 is an area in which a multi-digit numerical value of a set value can be displayed. The numerical value selection area 72 is an area in which a user can select a desired numerical value from among a plurality of numerical values. The cursor 73 is an indication indicating a digit into which a numerical value can be input by selecting a numerical value in the numerical value selection area 72. The button 74 is a button for setting the numerical value displayed in the numerical value selection area 72 as a set value. The button 75 is a button for returning to the previous screen without setting a set value. The operation of the syringe pump 20 with respect to input of a set value via a screen such as that in FIG. 6 is similar to the operation of the smartphone 10 described with reference to FIGS. 4A to 4D, 5A, and 5B, and therefore a detailed description thereof will be omitted. By having the syringe pump 20 accept the input of a set value via a screen such as that in FIG. 6, it is possible to more effectively prevent erroneous operation without impairing the operability of the user in inputting the set value, even without an external device such as the smartphone 10.

Figure 7 is a flowchart showing an example of the procedure for a numerical value setting process executed by the smartphone 10. The operation of the smartphone 10 described with reference to Figure 7 corresponds to one of the information processing methods of an information processing device. The operation of each step in Figure 7 is executed based on the control by the control unit 11 of the smartphone 10. Note that, as in Figure 6, when the syringe pump 20 executes the numerical value setting process, the operation of each step in Figure 7 is executed based on the control by the control unit 211 of the syringe pump 20.

In step S1 of FIG. 7, the control unit 11 causes the output unit 15 to display a display area 41, 61 capable of displaying a number with multiple digits, and a number selection area 42, 62 capable of selecting a desired number from among multiple numbers.

In step S2, the control unit 11 accepts a selection of the most significant digit in the display area 41, 61 from the user.

If the most significant digit is selected in step S2, in step S3, the control unit 11 causes the output unit 15 to display a cursor 43, 63 at the most significant digit of the display area 41, 61.

In step S4, the control unit 11 accepts the selection of a numerical value via the numerical value selection areas 42 and 62.

In step S5, the control unit 11 determines whether or not a number has been selected via the number selection area 42, 62. If a number has been selected (YES in step S5), the control unit 11 proceeds to step S6, and if not (NO in step S5), the control unit 11 proceeds to step S9.

In step S6, the control unit 11 causes the output unit 15 to display the number selected in step S4 in the digit where the cursor 43, 63 is displayed.

In step S7, the control unit 11 determines whether the cursor 43, 63 displayed in the display area 41, 61 is in the lowest digit. If it is in the lowest digit (YES in step S7), the control unit 11 proceeds to step S10, and if it is not (NO in step S7), the control unit 11 proceeds to step S8.

In step S8, the control unit 11 moves the cursor 43, 63 to the lower digit in the display area 41, 61. Then, the process returns to step S4.

On the other hand, in step S9, the control unit 11 determines whether or not the user has instructed the user to end input. For example, the control unit 11 may determine that the user has instructed the user to end input when "Back" is selected on a screen such as that shown in FIG. 5B. If the user has instructed the user to end input (YES in step S9), the control unit 11 proceeds to step S10, and if not (NO in step S9), the control unit 11 returns to step S4.

In step S10, the control unit 11 erases the display of the cursors 43, 63 in the display areas 41, 61.

In step S11, the control unit 11 stores the input setting values displayed in the display areas 41 and 61 in the memory unit 12. Then, the control unit 11 ends the processing of the flowchart.

As described above, the smartphone 10 displays the display areas 41 and 61, which can display multiple digits, on the output unit 15, and accepts the selection of the most significant digit in the display areas 41 and 61 from the user. When the most significant digit is selected in the display areas 41 and 61, the smartphone 10 displays the selected values in the areas of the digits below the most significant digit in the display areas 41 and 61 in order on the output unit 15 in response to the user's selection of a value via the numeric value selection unit. The smartphone 10 stores the numeric values displayed in the areas of the digits below the most significant digit in the display areas 41 and 61 as set values in the storage unit 12. In this way, the smartphone 10 accepts the selection of the most significant digit from the user, and then displays the numeric values selected in the areas of the digits below the most significant digit in order in response to the numeric value selection, and stores the numeric values as set values. Therefore, it is possible to prevent the input of a numeric value beyond the most significant digit, and it is possible to prevent erroneous operation by the user. Furthermore, the smartphone 10 accepts input of numerical values through a numerical selection unit such as a numeric keypad that can select the numerical value of each digit, rather than through buttons that increment or decrement numerical values little by little, a jog dial, or a drum, so that the user can input numerical values with simple operations. Therefore, it is possible to effectively prevent erroneous operations without impairing the operability of the user when inputting setting values.

In addition, in FIG. 4A to FIG. 4D, an example is described in which the smartphone 10 selects the most significant digit and then displays the numerical values in order from the most significant digit in response to the selection of the numerical value, but the numerical value display method is not limited to this. For example, the smartphone 10 may display the numerical values in order from the least significant digit in response to the selection of the numerical value after the most significant digit has been selected. For example, in the case where the thousands digit is selected as the most significant digit as in FIG. 4B, if the numerical value "1" is selected, the smartphone 10 may display "1" in the 0.1 digit. If the numerical value "2" is subsequently selected, the smartphone 10 may move the display of "1" to the ones digit and display "2" in the 0.1 digit. If the numerical value "3" is subsequently selected, the smartphone 10 may move the display of "1" to the tens digit, move the display of "2" to the ones digit, and display "3" in the 0.1 digit. When displayed in this manner, the smartphone 10 can prevent the input of a number beyond the most significant digit, or, if the input number does not reach the most significant digit, can prevent the setting of a number with a different number of digits than the most significant digit due to an erroneous operation.

The smartphone 10 may also display, as a numeric value selection section, numeric value selection areas 42, 62 on the output unit 15, in which a desired numeric value can be selected from among a number of numeric values. In this way, by displaying the numeric value selection areas 42, 62 as a numeric value selection section, it is possible to easily implement the user interface described with reference to Figures 4A to 4D in a configuration equipped with a touch screen, such as a smartphone or tablet.

The smartphone 10 also accepts a selection of a number from the user via the number selection unit, provided that the most significant digit has been selected. In this way, selection of a number via the number selection unit is prohibited until the most significant digit has been selected, making it possible to effectively prevent erroneous operation by the user.

The smartphone 10 may also accept a selection of the most significant digit from the user by a touch operation on any of the digits in the display area 41, 61. In this way, the smartphone 10 accepts the selection of the most significant digit by a touch operation, so that the user can input a setting value using an intuitive user interface.

In addition, the smartphone 10 may display a cursor 43, 63 on the most significant digit of the display area 41, 61 in the output unit 15 in response to the user selecting the most significant digit. In this way, the cursor 43, 63 is displayed on the most significant digit, so that the user can easily confirm the selected most significant digit.

In addition, the smartphone 10 may display the selected number in the digit where the cursor 43, 63 is displayed in the output unit 15 in response to the user selecting a number via the number selection unit, and may also move the cursor 43, 63 to a lower digit by one digit. In this way, the smartphone 10 displays the selected number at the position of the cursor 43, 63 in response to the user selecting a number via the number selection unit, and moves the cursor 43, 63 to a lower digit by one digit, so that the user can operate the number selection unit to input numbers in order from the most significant digit. Therefore, the user can input the setting value with a simple operation similar to that of inputting a number using a general calculator, so that it is possible to more effectively prevent erroneous operation without impairing the user's operability in inputting the setting value.

In addition, when the cursor 43, 63 is displayed in the lowest digit of the display area 41, 61, and the user selects a number via the number selection unit, the smartphone 10 may display the selected number in the digit where the cursor 43, 63 is displayed in the output unit 15, and may erase the display of the cursor 43, 63. In this way, the smartphone 10 can prevent erroneous operation by the user by erasing the cursor 43, 63 and ending the number input in response to the input of a number in the lowest digit.

The smartphone 10 also transmits the setting values stored in the memory unit 12 to a medical device such as a syringe pump 20 via the communication unit 13. In this way, since the setting values input in an information processing device such as the smartphone 10 are transmitted to the medical device, even if it is difficult to provide a user interface on the medical device, the setting values can be input by operating the information processing device, making it possible to more effectively prevent erroneous operation without impairing user operability.
