The pressing mechanism 28 may be connected to the infusion control device 20 as an external mechanism, rather than being provided in the infusion control device 20.

[0045] At least some of the functions of the infusion control device 20 are realized by executing the program according to this embodiment on the processor acting as the control unit 21.

Then, the computer reads the program stored in the main memory with its processor and executes the processing according to the read program. The computer may also read the program directly from the portable medium and execute the processing according to the program. The computer may also execute the processing according to the received program sequentially each time a program is transferred to the computer from a server.

"ASP" is an abbreviation for application service provider. A program includes information used for processing by an electronic computer that is equivalent to a program. For example, data that is not a direct instruction to the computer but has the nature of defining the computer's processing falls under "equivalent to a program".

[0048] Some or all of the functions of the infusion control device 20 may be implemented by a programmable circuit or a dedicated circuit as a control unit 21. In other words, some or all of the functions of the infusion control device 20 may be implemented by hardware.

[0049] The outline of this embodiment will be described with reference to Figures 1 and 2.

[0050] The detection unit 27 of the infusion control device 20 detects droplets of the infusion solution being administered to the patient through the tube 12. The pressing mechanism 28 of the infusion control device 20 presses the tube 12. Based on the detection result obtained by the detection unit 27, the control unit 21 of the infusion control device 20 controls the pressing mechanism 28 to adjust the drip rate of the infusion solution.

[0051] The control unit 21 of the infusion control device 20 controls the voice call VC with the external device, the terminal device 31. The input unit 25 of the infusion control device 20 acquires a first voice V1. The conversion unit 24 of the infusion control device 20 converts the first voice V1 acquired by the input unit 25 into first voice data D1. The communication unit 23 of the infusion control device 20 acquires the first voice data D1 from the conversion unit 24 and transmits it to the terminal device 31 from the start to the end of the voice call VC, and also receives the second voice data D2 from the terminal device 31 and inputs it to the conversion unit 24. The conversion unit 24 converts the input second voice data D2 into second voice V2. The output unit 26 of the infusion control device 20 outputs the second voice V2 obtained by the conversion unit 24 to the patient.

[0052] According to this embodiment, it becomes easier for patients and healthcare workers to communicate with each other during intravenous fluid administration. For example, even in situations where a hospitalized patient is hesitant to use the room-wide nurse call system, the patient and nurse can communicate individually as needed.

[0053] Refer to Figure 2 to explain an example of the application of the infusion control device 20.

[0054] In this example, the infusion control device 20 further comprises a box-shaped housing 20A. The housing 20A houses a microphone 25A and a speaker 26A. The housing 20A also at least partially houses a detection unit 27 and a pressing mechanism 28. The housing 20A may further house a control unit 21, a storage unit 22, a communication unit 23, and a conversion unit 24. The housing 20A may further house a battery as a power source for the infusion control device 20.

[0055] The microphone 25A is positioned on the housing 20A at a location corresponding to the lower end 20D where the intravenous fluid is administered. Therefore, the microphone 25A is more likely to capture the patient's voice when the patient is lying down. This is because when the patient is lying down, the infusion control device 20 is considered to be at a higher position than the patient's face. More specifically, the microphone 25A is positioned on the edge of the lower end 20D of the housing 20A. Therefore, the microphone 25A is more likely to capture the patient's voice even when the patient is walking or moving in a wheelchair. This is because when the patient is moving, the infusion control device 20 is considered to be at a lower position than the patient's face or at about the same height as their face.

[0056] Speaker 26A is also positioned on the housing 20A at a location corresponding to the lower end 20D where the intravenous fluid is administered. Therefore, the sound output from speaker 26A is easily audible when the patient is lying down. More specifically, speaker 26A is positioned on the edge of the lower end 20D of the housing 20A. Therefore, the sound output from speaker 26A is easily audible even when the patient is walking or moving in a wheelchair.

[0057] In the example shown in Figure 2, a liquid such as saline solution or nutritional supplement is injected into the patient's body via the drip chamber 11 and the tube 12. The housing 20A has a drip chamber housing section 20B that houses the drip chamber 11 and a tube housing section 20C that houses the upper end portion of the tube 12.

[0058] The drip chamber 11 has an inlet 11A, a dripping section 11B, and an outlet 11C. The inlet 11A, dripping section 11B, and outlet 11C are arranged in this order facing downwards in the vertical direction. The outlet 11C is connected to the upper end of the tube 12. Liquid that flows into the drip chamber 11 from a liquid container such as an infusion bag through the inlet 11A drips down in the dripping section 11B, flows out of the drip chamber 11 through the outlet 11C, and is injected into the patient's body through the tube 12. The amount of liquid dripped in the dripping section 11B corresponds to the flow rate of liquid injected into the patient's body, i.e., the flow rate of the infusion.

[0059] The detection unit 27 detects the liquid dripping in the dripping section 11B. The pressing mechanism 28 can be configured in any way as long as it functions as an electric clamp, but in the example shown in Figure 2, it has a cam 28A, a pressing member 28B, an electric motor 28C, and a reduction gear 28D. The control unit 21 controls the rotation of the cam 28A by controlling the rotation direction, rotation position, and rotation speed of the output shaft of the electric motor 28C according to the detection result of the detection unit 27. The reduction gear 28D transmits the rotation of the output shaft of the electric motor 28C to the cam 28A at a reduced rotation speed. The electric motor 28C allows the cam 28A to be used in a wide angular range such as 360°, and the angle is easy to control. The outer circumferential surface of the cam 28A rotates around the rotation axis O as the cam 28A rotates. The pressing member 28B presses the target portion 12A of the tube 12 by being pressed by the outer circumferential surface of the cam 28A. The target portion 12A of the tube 12 is restricted from moving within the tube housing 20C so that it is narrowed and its flow rate is reduced by being pressed from one side by the pressing member 28B. The pressing member 28B is held in the housing 20A so that it can move forward relative to the target portion 12A to narrow the target portion 12A and reduce the flow rate, and can move backward relative to the target portion 12A to expand the target portion 12A of the tube 12 by its elastic force and increase the flow rate.

[0060] Specifically, the control unit 21 rotates the cam 28A selectively to one side in the circumferential direction and the other side in the circumferential direction according to the detection result of the detection unit 27. When the cam 28A rotates to the other side in the circumferential direction, the radius at the point of contact between the outer circumferential surface of the cam 28A and the rear end of the pressing member 28B increases, causing the rear end of the pressing member 28B to be pressed by the outer circumferential surface of the cam 28A against the reaction force from the tube 12 acting on the front end of the pressing member 28B. As a result, the pressing member 28B moves forward. On the other hand, when the cam 28A rotates to one side in the circumferential direction, the radius at the point of contact between the outer circumferential surface of the cam 28A and the rear end of the pressing member 28B decreases, causing the pressing member 28B to retract due to the pressing force from the tube 12. To assist the retraction movement of the pressing member 28B, a biasing member such as a spring that biases the pressing member 28B in the retraction direction may be provided.

[0061] Referring to Figure 3, a first configuration example of the nurse call system 30 will be described.

[0062] In the first configuration example, the nurse call system 30 includes, in addition to the terminal device 31 and display device 32, a multifunction telephone 33, a board-type master unit 34, a call button 35A, an indicator light 35B, a reset button 35C, an antenna device 36 such as a mobile communication base station, a telephone control device 37 such as a PBX, a nurse call control device 38, and network equipment 39 such as a switch. "PBX" is an abbreviation for private branch exchange.

[0063] The terminal device 31 is held by a nurse. The display device 32, the multifunction telephone 33, and the board-type master unit 34 are installed in the nurses' station. The display device 32 is installed, for example, next to the board-type master unit 34.

The antenna device 36 and the telephone control device 37 are installed in or near the nurses' station. The nurse call control device 38 and the network equipment 39 are installed in any location within the medical facility, such as a server room.

[0064] When a patient presses the call button 35A, a nurse call request is sent from the call button 35A to the nurse call control device 38 via the network device 39, and the indicator light 35B illuminates. When the nurse call control device 38 receives a nurse call request, it simultaneously sends a notification to the terminal device 31 and the board-type master unit 34. When the terminal device 31 receives the notification via the telephone control device 37 and the antenna device 36, it notifies the nurse of the incoming nurse call with an audible ringtone, vibration, or both. When the board-type master unit 34 receives the notification via the network device 39, it notifies the nurse of the incoming nurse call with an audible ringtone. When a nurse receives the nurse call on the terminal device 31 or the board-type master unit 34, the patient and the nurse can communicate with each other. When the nurse rushes to the patient's room or toilet and presses the reset button 35C, the indicator light 35B turns off.

[0065] The multifunction telephone 33 is connected to the telephone control unit 37 and is used for at least internal telephone calls. The terminal device 31 may be used not only for nurse calls but also for internal telephone calls.

[0066] Referring to Figure 4, a second example configuration of the nurse call system 30 will be described.

[0067] In the second configuration example, the nurse call system 30 includes, in addition to the terminal device 31 and display device 32, a multifunction telephone 33, a call button 35A, an indicator light 35B, a reset button 35C, an antenna device 36 such as a mobile communication base station, and a telephone control device 37 such as a PBX.

[0068] The terminal device 31 is held by a nurse. The display device 32 and the multifunction telephone 33 are installed in the nurse's station. The call button 35A, indicator light 35B, and reset button 35C are installed in the patient's room, toilet, or both. The antenna device 36 is installed in or near the nurse's station. The telephone control device 37 is installed anywhere within the medical facility.

[0069] When a patient presses the call button 35A, a nurse call request is sent from the call button 35A to the terminal device 31 via the telephone control device 37 and the antenna device 36, and the indicator light 35B illuminates. When the terminal device 31 receives a nurse call request, it notifies the nurse of the incoming nurse call with an audible ringtone, vibration, or both. When the nurse receives the nurse call on the terminal device 31, the patient and the nurse can communicate with each other. When the nurse rushes to the patient's room or toilet and presses the reset button 35C, the indicator light 35B turns off.

[0070] The multifunction telephone 33 is connected to the telephone control device 37, as in the first configuration example, and is used for at least internal telephone calls. The terminal device 31 may be used not only for nurse calls but also for internal telephone calls.

[0071] Referring to Figure 5, a third configuration example of the nurse call system 30 will be described.

[0072] In the third configuration example, the nurse call system 30 includes, in addition to the terminal device 31 and display device 32, a multifunction telephone 33, a call button 35A, an indicator light 35B, a reset button 35C, an antenna device 36 such as a wireless LAN access point, a telephone control device 37 such as a PBX, and network equipment 39 such as a router.

[0073] The terminal device 31 is held by a nurse. The display device 32 and the multifunction telephone 33 are installed in the nurse's station. The call button 35A, indicator light 35B, and reset button 35C are installed in the patient's room, toilet, or both. The antenna device 36 and the telephone control device 37 are installed in or near the nurse's station. The network equipment 39 is installed in any location within the medical facility, such as a server room.

[0074] When a patient presses the call button 35A, a nurse call request is sent from the call button 35A to the terminal device 31 via the network device 39 and antenna device 36, and the indicator light 35B illuminates. When the terminal device 31 receives a nurse call request, it notifies the nurse of the incoming nurse call with an audible ringtone, vibration, or both. When the nurse receives the nurse call on the terminal device 31, the patient and the nurse can communicate with each other. When the nurse rushes to the patient's room or toilet and presses the reset button 35C, the indicator light 35B turns off.

[0075] The multifunction telephone 33 is connected to the telephone control unit 37, as in the first and second configuration examples, and is used for at least internal telephone calls. The terminal device 31 is not connected to the telephone control unit 37, but may be used not only for nurse calls but also for internal telephone calls via the IP network. "IP" is an abbreviation for Internet Protocol.

[0076] In any of the first to third configurations, when infusion of a patient begins, the control unit 21 of the infusion control device 20 controls the communication unit 23 to transmit information regarding the status of the infusion, such as the patient's infusion time, the amount of infusion, and the remaining time for infusion, to the display device 32. When the display device 32 receives the information regarding the status of the infusion, it displays the received information as shown in Figure 6. In the third configuration, similar information may also be transmitted to the terminal device 31. When the terminal device 31 receives the information regarding the status of the infusion, it displays the received information.

[0077] When the remaining time for the patient's intravenous fluid administration reaches a preset time, such as 5 minutes, the control unit 21 of the intravenous fluid control device 20 controls the communication unit 23 to send request data D3 to the terminal device 31 requesting the start of a voice call (VC). Upon receiving the request data D3, the terminal device 31 notifies the nurse of the incoming voice call (VC) with a ringtone, vibration, or both, similar to when a nurse call is received. When the nurse receives the voice call (VC) on the terminal device 31, the terminal device 31 sends response data D4 to the intravenous fluid control device 20 acknowledging the start of the voice call (VC) in accordance with the request data D3. Upon receiving the response data D4 by the communication unit 23, the control unit 21 of the intravenous fluid control device 20 starts the voice call (VC). As a result, the patient and the nurse can communicate with each other. For example, the nurse can say, "Ms. AA, I'll come check on you in X minutes," and the patient can reply, "Yes, please."

[0078] When the remaining time for a patient's infusion reaches a preset time, such as 5 minutes, the display device 32 automatically updates the task management table and displays the updated task management table along with an alert about the remaining time for the infusion, as shown in Figure 7. The task management table includes information such as the scheduled end time for each patient's infusion on the day, and whether each patient's infusion has actually been completed. The alert includes, for example, a message such as "AA 5 minutes left," the illumination of a warning lamp, a warning sound, or any combination thereof. In the third configuration example, a similar task management table may be viewable on the terminal device 31.

[0079] The settings for the infusion, such as the patient's infusion time, infusion volume, or drip rate, may be remotely controlled from the terminal device 31 to the infusion control device 20.

[0080] Referring to Figure 8, the operation of the infusion control device 20 according to this embodiment will be described. This operation corresponds to the management method according to this embodiment.

[0081] In step S101, the detection unit 27 of the infusion control device 20 detects droplets of the infusion solution being administered to the patient through the tube 12.

[0082] In step S102, the control unit 21 of the infusion control device 20 controls the pressing mechanism 28 to adjust the drip rate of the infusion agent based on the detection result obtained by the detection unit 27 in step S101. The drip rate is determined by dividing the number of detected droplets by the time.

[0083] In step S103, the control unit 21 of the infusion control device 20 determines whether the first event E1 has occurred. Specifically, the control unit 21 measures the administration time of the infusion while the infusion is being administered. The control unit 21 determines whether the first event E1 has occurred based on whether the remaining time until the set administration time falls below the threshold T1. That is, the control unit 21 determines that the first event E1 has not occurred if the remaining time until the set administration time is not below the threshold T1. The control unit 21 determines that the first event E1 has occurred if the remaining time until the set administration time falls below the threshold T1. The threshold T1 may be uniformly set as a fixed value such as 5 minutes, or it may be set individually for each patient or for each type of infusion.

[0084] As one variation, the control unit 21 of the infusion control device 20 may measure the amount of infusion solution administered while the infusion solution is being infused. The control unit 21 may determine whether the first event E1 has occurred based on whether the remaining amount up to the set dose falls below the threshold T2. That is, the control unit 21 may determine that the first event E1 has not occurred if the remaining amount up to the set dose is not below the threshold T2. The control unit 21 may determine that the first event E1 has occurred if the remaining amount up to the set dose falls below the threshold T2. The threshold T2 may be set uniformly as a fixed value, or it may be set individually.

[0085] As another variation, the control unit 21 of the infusion control device 20 may determine whether the first event E1 has occurred based on whether the input unit 25 has received an operation R1 from the patient requesting the initiation of a voice call VC. That is, the control unit 21 may determine that the first event E1 has not occurred if operation R1 has not been performed. The control unit 21 may determine that the first event E1 has occurred if operation R1 has been performed. Operation R1 may be performed by voice via the microphone 25A, or via another input interface.

[0086] If it is determined in step S103 that the first event E1 has not occurred, that is, if the first event E1 has not been detected, the process in step S103 is executed again. If it is determined in step S103 that the first event E1 has occurred, that is, if the first event E1 has been detected, the process in step S104 is executed.

[0087] In step S104, the control unit 21 of the infusion control device 20 initiates a voice call (VC) with the terminal device 31. Specifically, the control unit 21 controls the communication unit 23 to send request data D3 to the terminal device 31 requesting the initiation of a voice call (VC). When the communication unit 23 receives response data D4 in response to the request data D3, the control unit 21 initiates the voice call (VC).

[0088] The microphone 25A of the infusion control device 20 acquires the first voice V1. The first voice V1 is the patient's voice. The conversion unit 24 of the infusion control device 20 converts the first voice V1 acquired by the microphone 25A into first voice data D1. The first voice data D1 is digital data of the patient's voice. The communication unit 23 of the infusion control device 20 acquires the first voice data D1 from the conversion unit 24 and transmits it to the terminal device 31 from the start to the end of the voice call VC, and also receives the second voice data D2 from the terminal device 31 and inputs it to the conversion unit 24. The second voice data D2 is digital data of the voice of a medical professional such as a nurse. The conversion unit 24 converts the input second voice data D2 into second voice V2. The second voice V2 is the voice of a medical professional. The speaker 26A of the infusion control device 20 outputs the second voice V2 obtained by the conversion unit 24 toward the patient.

[0089] In step S105, the control unit 21 of the infusion control device 20 determines whether the second event E2 has occurred. Specifically, the control unit 21 determines whether the second event E2 has occurred based on whether the input unit 25 has received the patient's operation R2 requesting the termination of the voice call VC. That is, the control unit 21 determines that the second event E2 has not occurred if operation R2 has not been performed. The control unit 21 determines that the second event E2 has occurred if operation R2 has been performed. Operation R2 may be performed by voice via the microphone 25A, or via another input interface.

[0090] If it is determined in step S105 that the second event E2 has not occurred, that is, if the second event E2 has not been detected, the process in step S105 is executed again. If it is determined in step S105 that the second event E2 has occurred, that is, if the second event E2 has been detected, the process in step S106 is executed.

[0091] In step S106, the control unit 21 of the infusion control device 20 terminates the voice call VC with the terminal device 31.

[0092] In steps S103 and S104, the voice call VC is automatically started triggered by a request from the infusion control device 20, but the voice call VC may also be started triggered by a command from the terminal device 31. In such a modified example, when the control unit 21 of the infusion control device 20 receives command data D5 commanding the start of the voice call VC from the communication unit 23, it starts the voice call VC in accordance with the command data D5. Specifically, the control unit 21 measures the administration time of the infusion while the infusion is being administered. When the control unit 21 determines that the remaining time until the set administration time is less than or equal to the threshold T1, it controls the communication unit 23 to transmit the obtained determination result to the terminal device 31. Alternatively, the control unit 21 may measure the amount of infusion administered while the infusion is being administered. When the control unit 21 determines that the remaining time until the set dose is less than or equal to the threshold T2, it may control the communication unit 23 to transmit the obtained determination result to the terminal device 31. When the terminal device 31 receives the judgment result, if the threshold T1 is 5 minutes, it displays or outputs an alert such as "AA 5 minutes before". When the nurse performs operation R3 to request the start of a voice call VC at the terminal device 31, command data D5 is transmitted from the terminal device 31 to the infusion control device 20. When the control unit 21 receives the command data D5 by the communication unit 23, it starts a voice call VC in accordance with the command data D5. Operation R3 may be performed by voice via the microphone of the terminal device 31, or via another input interface of the terminal device 31.

[0093] This embodiment offers benefits such as reduced travel distance, improved patient confidence, and increased work efficiency for healthcare professionals. Because it facilitates fluid management not only when patients are hospitalized but also at home, it makes task management easier for staff such as nurses and caregivers. The fluid control device 20 can also be used as a means of communication during disasters. The fluid control device 20 is particularly useful in areas with a shortage of healthcare professionals. Because the fluid control device 20 can be made compact and lightweight, it is easy to handle. The fluid control device 20 can also be used for central venous nutrition in nursing homes where staffing shortages are common, and cost reduction can be expected. The fluid control device 20 can also address wandering in dementia patients.

[0094] The following will explain the effects in more detail.

[0095] This embodiment makes it easier to prevent oversights due to excessive workload or burden on healthcare professionals. For example, even if a nurse is responsible for 5 to 10 patients, the infusion control device 20 can notify the nurse of the infusion status, allowing the nurse to simultaneously monitor the medication status of all patients from outside the patient's room. Integration with a task management application is also possible, enabling smooth task management. Alerts such as "AA 5 minutes before" are output when necessary, reducing the possibility of overlooking medication management.

[0096] According to this embodiment, the patient's psychological state can also be easily improved. For example, since conversation is possible using the communication function of the infusion control device 20, the patient's anxiety can be alleviated. Individual conversations are possible even at night. Individual conversations are also possible when moving outside the patient's room, such as to the toilet.

[0097] According to this embodiment, it becomes easier to obtain information regarding the evacuation status of patients in the event of a disaster. For example, since conversation is possible using the communication function of the infusion control device 20, it is possible to check whether patients who have evacuated from the ward are safe, where they have evacuated to, their medical condition, medication status, psychological state, or the surrounding circumstances. For when communication infrastructure becomes unavailable, an analog radio may be installed on the infusion control device 20. To allow for detailed confirmation of the patient's location, a GNSS receiver may be installed on the infusion control device 20. "GNSS" is an abbreviation for global navigation satellite system. Examples of GNSS include GPS, QZSS, BDS, GLONASS, or Galileo. "GPS" is an abbreviation for Global Positioning System. "QZSS" is an abbreviation for Quasi-Zenith Satellite System. QZSS satellites are called quasi-zenith satellites. "BDS" is an abbreviation for BeiDou Navigation Satellite System. "GLONASS" is an abbreviation for Global Navigation Satellite System.

[0098] Referring to Figure 9, the configuration of the management system 10A according to a modified example of this embodiment will be described. Parts similar to the configuration of the management system 10 shown in Figure 1 will be omitted or simplified as appropriate.

[0099] The management system 10 comprises an infusion control system 13, a nurse call system 30, and at least one management device 40. The infusion control system 13 comprises at least one holding device 60, at least one infusion control device 20, at least one infusion control device 20E, or both. The holding device 60 communicates with the terminal device 31, the display device 32, and the management device 40 via the network 50.

[0100] The holding device 60, the infusion control device 20, and the infusion control device 20E are used in medical facilities such as hospitals in this modified example, but they may also be used in other types of facilities such as nursing homes. The holding device 60 is a device that holds the infusion control device 20, the infusion control device 20E, or both. The infusion control device 20E is a device that omits the voice communication function FC from the infusion control device 20.

[0101] Referring to Figure 9, the configuration of the holding device 60 according to this modified example will be explained.

[0102] The holding device 60 comprises a control unit 61, a storage unit 62, a communication unit 63, a conversion unit 64, an input unit 65, an output unit 66, and a holding unit 67.

[0103] The control unit 61 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or any combination thereof. The processor is a general-purpose processor such as a CPU or GPU, or a dedicated processor specialized for a specific process. The programmable circuit is, for example, an FPGA. The dedicated circuit is, for example, an ASIC. The control unit 61 controls each part of the holding device 60 and executes processes related to the operation of the holding device 60.

[0104] The storage unit 62 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or any combination thereof. The semiconductor memory is, for example, RAM, ROM, or flash memory. The RAM is, for example, SRAM or DRAM. The ROM is, for example, EEPROM. The flash memory is, for example, SSD. The magnetic memory is, for example, HDD. The storage unit 62 functions, for example, as a main memory, auxiliary memory, or cache memory. The storage unit 62 stores data used for the operation of the retaining device 60 and data obtained by the operation of the retaining device 60.

[0105] The communication unit 63 includes at least one communication interface. The communication interface is, for example, an interface compatible with mobile communication standards such as LTE, 4G, or 5G; an interface compatible with short-range wireless communication such as Bluetooth®; an interface compatible with wireless LAN communication standards such as IEEE 802.11; or an interface compatible with wired LAN communication standards such as Ethernet®. The communication unit 63 communicates with the terminal device 31, the display device 32, and the management device 40. The communication unit 63 may also communicate with the infusion control device 20, the infusion control device 20E, or both. The communication unit 63 receives data used for the operation of the holding device 60 and transmits data obtained by the operation of the holding device 60.

[0106] The conversion unit 64 includes an analog-to-digital conversion circuit, a signal processing circuit such as a DSP, and a digital-to-analog conversion circuit. The conversion unit 64 may further include an amplifier. The conversion unit 64 converts an analog audio signal into digital data and converts the digital audio data into an analog signal.

[0107] The input unit 65 includes a microphone 65A. The input unit 65 may further include other input interfaces. These input interfaces may be, for example, physical keys, capacitive keys, a pointing device, or a touchscreen integrated with a display. The input unit 65 accepts operations to input data used for the operation of the holding device 60. The microphone 65A acquires the patient's voice as a first voice V1.

[0108] The output unit 66 includes a speaker 66A. The output unit 66 may further include other output interfaces, such as a display. The display is, for example, an LCD or an organic EL display. The output unit 66 outputs data obtained by the operation of the holding device 60. The speaker 66A outputs the voice of a medical professional, such as a nurse, as a second voice V2.

[0109] The holding section 67 includes a mechanism for holding the infusion control device 20, the infusion control device 20E, or both. For example, a rack can be used as such a mechanism. The holding section 67 may also have a structure for connecting and holding multiple infusion control devices.

[0110] At least some of the functions of the holding device 60 are realized by executing the program according to this modified example on the processor acting as the control unit 61. In other words, at least some of the functions of the holding device 60 are realized by software. The program causes the computer to function as the holding device 60 by having the computer perform the operations of the holding device 60. That is, the computer functions as the holding device 60 by performing the operations of the holding device 60 according to the program.

[0111] Some or all of the functions of the holding device 60 may be implemented by a programmable circuit or a dedicated circuit as a control unit 61. In other words, some or all of the functions of the holding device 60 may be implemented by hardware.

[0112] Refer to Figure 9 to explain the outline of this modified example.

[0113] The holding portion 67 of the holding device 60 holds the infusion control device 20, the infusion control device 20E which adjusts the drip rate of the infusion by controlling a pressing mechanism that presses the tube based on the detection result obtained by detecting droplets of the infusion solution being dripped to the patient through the tube, similar to the infusion control device 20, or both.

[0114] The control unit 61 of the holding device 60 controls the voice call VC with the external device, the terminal device 31. The input unit 65 of the holding device 60 acquires the first voice V1. The conversion unit 64 of the holding device 60 converts the first voice V1 acquired by the input unit 65 into first voice data D1. The communication unit 63 of the holding device 60 acquires the first voice data D1 from the conversion unit 64 and transmits it to the terminal device 31 from the start to the end of the voice call VC, and also receives the second voice data D2 from the terminal device 31 and inputs it to the conversion unit 64. The conversion unit 64 converts the input second voice data D2 into second voice V2. The output unit 66 of the holding device 60 outputs the second voice V2 obtained by the conversion unit 64 to the patient.

[0115] According to this modified version, even without a voice communication function (FC) in the infusion control device 20E, it becomes easier for the patient and healthcare worker to communicate with each other during infusion.

[0116] Referring to Figure 10, the operation of the infusion control system 13 according to this modified example will be explained. This operation corresponds to the management method according to this modified example.

[0117] In step S201, the control unit 61 of the holding device 60 determines whether the infusion control device held by the holding unit 67 has a function FC for voice communication VC. Specifically, the control unit 61 determines whether the infusion control device has a function FC by checking whether it has received a signal indicating that it has a function FC transmitted from the infusion control device held by the holding unit 67 via the communication unit 63, such as an interface compatible with short-range wireless communication.

[0118] If, in step S201, it is determined that the infusion control device held by the holding part 67 of the holding device 60 has a function FC, that is, if it is determined that the infusion control device 20 is held by the holding part 67, then the process in step S202 is executed. If, in step S201, it is determined that the infusion control device held by the holding part 67 of the holding device 60 does not have a function FC, that is, if it is determined that only the infusion control device 20E is held by the holding part 67, then the process in step S203 is executed.

[0119] In step S202, the control unit 61 of the holding device 60 controls the infusion control device 20, which is held by the holding unit 67, to disable function FC. Specifically, the control unit 61 commands the infusion control device 20 to turn off the microphone 25A via the communication unit 63, such as an interface compatible with short-range wireless communication.

[0120] In step S203, the infusion control device held by the holding unit 67 detects droplets of the infusion solution being administered to the patient through the tube.

[0121] In step S204, the infusion control device held by the holding unit 67 controls the pressing mechanism to adjust the drip rate of the infusion agent based on the detection result obtained in step S201.

[0122] In step S205, the control unit 61 of the holding device 60 determines whether the first event E1 has occurred. Specifically, the infusion control device held by the holding unit 67 measures the administration time of the infusion while the infusion is being administered. When the infusion control device held by the holding unit 67 determines that the remaining time until the set administration time is less than or equal to the threshold T1, it notifies the control unit 61. Alternatively, the infusion control device held by the holding unit 67 may measure the amount of infusion administered while the infusion is being administered. When the infusion control device held by the holding unit 67 determines that the remaining time until the set dose is less than or equal to the threshold T2, it may notify the control unit 61. Upon receiving the notification, the control unit 61 determines that the first event E1 has occurred. Alternatively, the control unit 61 may determine whether the first event E1 has occurred based on whether the input unit 65 has received a patient operation R1 requesting the start of a voice call VC.

[0123] If it is determined in step S205 that the first event E1 has not occurred, that is, if the first event E1 has not been detected, the process in step S205 is executed again. If it is determined in step S205 that the first event E1 has occurred, that is, if the first event E1 has been detected, the process in step S206 is executed.

[0124] The process in step S206 is the same as the process in step S104 shown in Figure 8, except that the parts of the holding device 60 operate and are executed instead of the parts of the infusion control device 20. Therefore, the explanation is omitted.

[0125] The processes in steps S207 and S208 are the same as those in steps S105 and S106 shown in Figure 8, except that the parts of the holding device 60 operate instead of the parts of the infusion control device 20, so their explanation will be omitted.

[0126] In steps S205 and S206, the voice call VC is automatically started triggered by a request from the holding device 60, but the voice call VC may also be started triggered by a command from the terminal device 31. In such a modified example, when the control unit 61 of the holding device 60 receives command data D5 commanding the start of the voice call VC from the communication unit 63, it starts the voice call VC in accordance with the command data D5. Specifically, the infusion control device held by the holding unit 67 measures the administration time of the infusion agent while the infusion agent is being infused. When the infusion control device held by the holding unit 67 determines that the remaining time until the set administration time is less than or equal to the threshold T1, it notifies the control unit 61. Alternatively, the infusion control device held by the holding unit 67 may measure the amount of infusion agent administered while the infusion agent is being infused. When the infusion control device held by the holding unit 67 determines that the remaining time until the set dose is less than or equal to the threshold T2, it notifies the control unit 61. When the control unit 61 receives a notification, it controls the communication unit 63 to transmit the obtained judgment result to the terminal device 31. When the terminal device 31 receives the judgment result, if the threshold T1 is 5 minutes, it displays or outputs an alert such as "AA 5 minutes away" via voice. When the nurse performs operation R3 to request the start of a voice call VC at the terminal device 31, command data D5 is transmitted from the terminal device 31 to the holding device 60. When the control unit 61 receives the command data D5 via the communication unit 63, it starts a voice call VC according to the command data D5.

[0127] As another variation from this one, the control unit 61 of the holding device 60 may, when multiple infusion control devices, each having a voice communication function FC, are held by the holding unit 67, select one of the multiple infusion control devices, command the selected infusion control device to turn on its microphone, and command the remaining infusion control devices to turn off their microphones. The control unit 61 may also turn off the microphone 65A of the holding device 60.

[0128] This disclosure is not limited to the embodiments described above. For example, multiple blocks described in the block diagram may be combined, or a single block may be divided. Instead of executing multiple steps described in the flowchart in chronological order as described, they may be executed in parallel or in a different order, depending on the processing capacity of the device performing each step, or as necessary. Other modifications are possible without departing from the spirit of this disclosure. [Explanation of Symbols]
