JP 2003-290345 A

As described above, when the infusion pump is configured so that it can be remotely operated, it is not necessary to directly operate the infusion device, which is convenient, but settings (command values) such as the infusion flow rate are changed by inadvertent button operation. There was a possibility.
Also, in remote operation, it is necessary to perform setting operations such as flow rate / scheduled amount at the start of infusion, for example, doctors can not set flow rate / scheduled amount in advance according to their prescription, When there are a plurality of infusion pumps, there is a problem that it is difficult to accurately set the operation of each infusion pump while confirming the patient and the medicine container.
The objective of this invention is providing the infusion pump which can set the setting value of the infusion operation | movement more accurately.

  An infusion pump according to the present invention includes a pump body that infuses a liquid to be transported, an operation unit that sets a command value of an infusion operation in the pump body, and a storage unit that stores a command value set by the operation unit. A portable setting terminal, and a short-range communication device that performs communication in a state where the pump main body and the setting terminal are close to each other, provided in the pump main body and the setting terminal, respectively. The command value stored in the storage unit is transmitted to the pump main body by the short-range communication device, and the pump main body performs an infusion operation according to the command value.

  Here, the short-range communication device may be a communication device that performs short-range wireless communication, and the short-range communication device may be a communication device that performs wired communication via a detachable connector. it can.

Further, the pump body includes an alarm transmission unit that wirelessly transmits an alarm signal indicating infusion operation abnormality toward the outside, while the setting terminal receives an alarm signal wirelessly transmitted from the alarm transmission unit of the pump body. An alarm receiving unit for receiving and an alarm sound generating unit for generating an alarm sound when the alarm signal is received, and the maximum communication distance between the alarm transmitting unit and the alarm receiving unit is the short-range communication device It may be set longer than the maximum communication distance in.
In the configuration including the alarm receiving unit / alarm transmitting unit, the pump main body generates an alarm sound when the infusion operation abnormality occurs, and an mute mode switch for selecting operation / stop of the alarm sound generating unit It is good to have.

Moreover, it is good for the said pump main body to be equipped with the mounting part which mounts | wears with the said setting terminal in the state in which the communication between the said pump main body and the said setting terminal by the said short-range communication device is possible.
In the configuration in which the pump body includes a mounting portion, the setting terminal includes a start switch that instructs the start of the infusion operation in the pump body, and the start command by the start switch is transmitted via the short-range communication device. It can be sent to the pump body.

The command value includes at least a flow rate and a predetermined amount of the liquid to be transported, and the setting terminal determines the completion time of the infusion based on the flow rate and the predetermined amount and a signal indicating the start time of the infusion operation in the pump body. And / or a calculation unit for calculating the remaining infusion time, and a display unit for displaying the infusion completion time and / or the remaining infusion time calculated by the calculation unit.
In the configuration including a calculation unit that calculates the completion time of the infusion and / or the remaining infusion time, a signal indicating the start of the infusion operation from the pump body when the calculation unit transmits a command value of the infusion operation. Can be determined as the start time of the infusion operation at any time when the time measurement start command switch provided in the setting terminal is operated.
Furthermore, the setting terminal may include a completion alarm generation unit that issues an alarm when the completion time is reached or when the remaining infusion time becomes zero.

  The pump body includes an operation unit for setting the command value, and a storage unit for storing the command value set by the operation unit, and the command value received from the setting terminal by the pump body and the command value The infusion operation can be started on condition that the command value stored in the storage unit of the pump body matches.

  In the infusion pump according to the present invention, the command value stored in the storage unit of the setting terminal is transmitted to the pump main body in a state where the pump main body and the portable setting terminal are close to each other, and the command value received by the pump main body Since the liquid to be transported is infused according to the command value, the command value at the setting terminal can be set in advance at the position away from the pump main body before the infusion starts, and the pump main body and the setting terminal are brought close to each other for transmission / reception of the command value. Since it is necessary, it is possible to avoid inadvertently setting the command value, and to the pump body while checking the living body and the liquid to be transported (infusion bag) at the site where injection into the living body (patient) is performed Command value can be transmitted, and the operation of the pump body can be set accurately.

  Further, if the command value is transmitted and received by short-range wireless communication, the command value can be easily transmitted to the pump body. In addition, when the command value is transmitted / received via wired communication via a detachable connector, it is possible to more reliably avoid inadvertent transmission / reception of the command value. Transmission and reception can be performed in a more stable state.

  In addition, if the setting terminal receives an alarm signal transmitted wirelessly from the pump body and an alarm is issued at the setting terminal, a nurse or the like who carries the setting terminal away from the pump body Recognize abnormal operation and take immediate action.

  In addition, if the generation of an alarm sound for abnormal operation in the pump body can be stopped arbitrarily, the patient's sleep can be prevented from being disturbed by the alarm sound being generated in the pump body at night, and the alarm signal can be set Since it is wirelessly transmitted to the terminal, for example, if a setting terminal is placed at the nurse station, the nurse can notice the occurrence of an abnormality and take necessary measures.

  In addition, by attaching a setting terminal to the pump body, even when short-range communication is performed wirelessly, communication stability can be ensured and operation setting can be performed reliably. In this case, even if the infusion operation of the pump body is started based on the signal of the start switch provided in the setting terminal, the operation start can be instructed exactly as in the start operation on the pump body side. If the infusion operation is started only by the operation, it is possible to avoid an inadvertent operation start without a setting terminal.

  In addition, if the infusion completion time and the remaining infusion time are predicted on the setting terminal side and the prediction result is displayed on the display unit, for example, the progress of the infusion can be confirmed on the display unit of the setting terminal placed on the nurse station. Therefore, the timing of going to the hospital room can be determined, and the infusion work can be performed efficiently. Furthermore, if the setting terminal issues an alarm when the infusion completion time or the remaining infusion time becomes zero, it is possible to avoid delaying the nurse from noticing the completion of the infusion.

  In addition, by comparing the command value set by the operation unit provided on the pump body with the command value transmitted from the setting terminal side, if the command value is set incorrectly, it is based on the incorrect command value. As a result, the pump body can be prevented from operating.

Hereinafter, an infusion pump according to an embodiment of the present invention will be described with reference to the drawings.
The infusion pump of this embodiment is used for administering a parenteral liquid (transported liquid) such as a nutrient solution or a chemical solution to a living body (patient) in the medical field.
FIG. 1 is a diagram illustrating a portable setting terminal 100 that is used in a pair with a pump main body 200 described later, and transmits and receives signals to and from the pump main body 200 by wireless communication.

  Although the wireless communication will be described in detail later, in the present embodiment, a command value for the planned infusion volume / flow rate is transmitted from the setting terminal 100 to the pump body 200, and the setting terminal 100 is transmitted from the pump body 200. In response to this, a signal indicating an abnormality of the pump body 200 is transmitted.

The setting terminal 100 shown in FIG. 1 has a thin box shape and is formed in a size and weight that can be operated with one hand, for example, in a pocket of a nurse's uniform. The setting terminal 100 operates using a built-in battery as a power source, and includes a liquid crystal display unit 110 and operation buttons (operation unit) 120.
The operation button 120 includes an up / down switch 121 for increasing / decreasing the flow rate (mL / h) and the predetermined amount (mL) in the infusion operation of the pump body 200 in units of 1, 10, 100, a buzzer (alarm) And a change-over switch 123 for selecting whether to set the flow rate (mL / h) or the predetermined amount (mL).

In addition to the above, the operation button 120 includes a power switch, a buzzer volume switching switch, a liquid crystal display switching switch, a key lock button that prohibits changing the settings of the flow rate (mL / h) and the scheduled volume (mL), and the like. May be provided.
Furthermore, a numeric keypad or the like can be provided as the operation button 120, and the flow rate (mL / h) and the scheduled volume (mL) can be set / changed by inputting a password using the numeric keypad. Further, instead of the operation button 120, a touch panel can be provided.

  In FIG. 1, the liquid crystal display unit 110 has a character display 111 of “pump abnormality” indicating abnormality in the pump body 200, “flow rate (mL / h)” and “scheduled amount” set by the up / down switch 121. (ML) "command value numerical display 112, 113, numerical value display 114 of infusion completion scheduled time according to the" flow rate (mL / h) "and" scheduled amount (mL) ", built-in battery of the setting terminal 100 A battery mark 115 indicating the remaining amount, a numerical display 116 indicating the current time, a character display 117 of “infusion completion” indicating completion of the infusion, and the like are displayed.

  As will be described later, the pump body 200 diagnoses whether there is an abnormality for each item such as “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, “requires charging”, and displays an alarm display for each item. Therefore, the setting terminal 100 receives from the pump main body 200 an abnormality signal for distinguishing which abnormality among the items has occurred, and the setting terminal 100 also receives the abnormality signal for each item based on the reception result. An alarm can be displayed.

In addition, the liquid crystal display unit 110 may display a wireless communication state (radio wave intensity or the like) with the pump body 200.
Further, instead of the numerical display 114 of the scheduled completion time of the infusion and the numerical display 116 indicating the current time, a numerical display of the remaining time of the infusion operation (time until the completion of the infusion) can be performed. Any one of a combination of a numerical display 114 of the scheduled completion time and a numerical display 116 indicating the current time and a numerical display of the remaining time of the infusion operation (time to complete the infusion) can be selectively displayed. .

The setting / changing of “flow rate (mL / h)” and “scheduled amount (mL)” in the setting terminal 100 is performed as follows.
When the changeover switch 123 is pressed, the numerical value display 113 of the predetermined amount on the liquid crystal display unit 110 blinks. When the up / down switch 121 is pressed in the blinking state, the numerical display 113 of the predetermined amount is kept flashing. When the changeover switch 123 is pressed once again when the expected amount reaches the required value, the expected amount is confirmed and the numerical display 113 stops blinking. The display 112 blinks.

When the up / down switch 121 is pressed while the numerical value display 112 of the flow rate is blinking, the numerical value display 112 of the flow rate is changed while maintaining the blinking state, and is switched again when the numerical value of the flow rate reaches the required value. When the switch 123 is pressed, the numerical value of the flow rate is confirmed, the blinking of the numerical value display 112 is stopped, and the setting of the scheduled amount and the flow rate is confirmed.
As described above, the scheduled amount and the numerical value of the flow rate set / changed by operating the up / down switch 121 are displayed on the liquid crystal display unit 110 and stored as data in a memory provided in the setting terminal 100. .

Further, the setting terminal 100 emits an alarm sound when the infusion is completed (when the scheduled infusion time is reached, when the remaining time of the infusion operation becomes zero) or when an abnormality occurrence signal is received from the pump body 200. A buzzer is provided, and when the mute switch 122 is pressed while the buzzer is sounding, the buzzer sound is muted.
Note that when the mute switch 122 is pressed for a long time without a buzzer sounding, it may be switched to a mute mode in which the buzzer is not sounded. In this case, the liquid crystal display unit 110 is in the mute mode state. It is preferable to display this.

The numerical display 114 of the scheduled completion time of the infusion displays a result calculated from the time required for the infusion operation calculated based on the setting of the predetermined amount and the flow rate and the time when the infusion operation is started. It has become. When the scheduled completion time is reached, the buzzer 160 (completion alarm generation unit) is sounded, and the character display 117 of “infusion completion” is blinked.
Note that the numerical display 114 of the scheduled completion time may be blinked instead of blinking the character display 117 of “infusion completion” when the scheduled completion time of the infusion is reached.

The display on the liquid crystal display unit (monitor) 110 can be automatically turned off (the monitor is turned off) when the non-operation state continues for a certain time or more. Switching from off (power off) to on (power on) can be performed when any of the operation buttons 120 is pressed.
Furthermore, when the liquid crystal display unit 110 is in an off state and a signal indicating the occurrence of an abnormality is received from the pump body 200 side, the liquid crystal display unit 110 can be set to be switched on.

FIG. 2 is a perspective view showing a pump main body 200 combined with the setting terminal 100 shown in FIG. 1, and the pump main body 200 operates using an AC power source or a built-in battery as a power source.
The pump body 200 is attached to a main body 201 provided with a peristaltic (peristallic finger type) pump as disclosed in, for example, Japanese Patent Publication No. 61-55393, and to the front surface of the main body 201 so as to be freely opened and closed. And a door 202.
On the front surface of the main body 201, a tube mounting portion for mounting a flexible tube connected to an infusion bag or the like along the vertical direction, and a crushing position by a finger of the tube mounted on the tube mounting portion are sequentially provided. And a peristaltic pump unit that is infused by being moved.

  The door 202 is provided with a door lock lever 203 used to open and close the door 202. When a tube connected to an infusion bag or the like is mounted on the tube mounting portion, the door lock lever 203 is operated to operate the door 202. When the installation is completed, the door 202 is closed and the door lock lever 203 is operated to lock the door 202 with respect to the main body 201.

A bag plate is provided on the inner surface of the door 202 to press the tube toward the pump portion of the main body portion 201 with a predetermined pressure. When the door 202 is in a locked state (closed state), the tube is a pump of the main body portion 201. The tube is crushed between the fingers of the pump part and the bag plate.
In FIG. 2, an insertion hole 204 provided in the upper portion of the door 202 is a hole for taking out the tube attached to the tube attachment portion to the outside.

A liquid crystal display unit 210 and operation buttons (operation unit) 220 are provided on the front surface of the door 202.
The liquid crystal display unit 210 has a character display 211 indicating “completed” indicating the completion of the infusion, and an alarm such as “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, “charge required” indicating abnormality in the pump body 200. Display 212, numerical display 213 of "flow rate (mL / h)", one of the numerical value of the counting result of "integrated amount (mL)" after the start of infusion and the numerical value of "scheduled amount (mL)" The integrated / scheduled amount display 214 to be displayed is displayed.

The pump body 200 includes abnormality detection means for detecting whether there is an abnormality of the “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, and “required charging”, and the abnormality detection means generates an abnormality. When the diagnosis is made, the alarm display 212 “Bubble mixed”, “That”, “Flow rate abnormality”, “Door open”, “Charge required” is blinked according to the abnormality occurrence item.
The “bubble mixing” is mixing of bubbles into a tube mounted on the tube mounting portion, and the presence / absence of the bubbles is determined by using an ultrasonic wave by a bubble detection unit provided on the front surface of the main body unit 201. Detected.

“That” (clogging) is the clogging of the tube on the downstream side of the pump. The occurrence of “that is” (clogging) is caused by the clogging of the tube by the clogging detection unit provided on the front surface of the main body 201. It is detected from the condition.
The “flow rate abnormality” is an abnormality of the actual flow rate with respect to the set flow rate. When an infusion probe for monitoring the instillation state in the infusion tube is connected to the pump body 200, the infusion of the instillation detected by the infusion probe is detected. The flow rate abnormality is detected from presence / absence and dropping timing.

“Door open” is a state in which the door 202 is not completely closed, and is detected based on a signal from a limit switch that detects opening / closing of the door 202.
Further, “required charge” indicates a voltage drop state of the battery built in the pump main body 200, and when the battery voltage falls below a threshold value (lower limit value of operation compensation), the determination of “required charge” is made.

  As the operation button 220, an integrated amount switch 221 for instructing switching between the display of “integrated amount (mL)” and the display of “planned amount (mL)” on the liquid crystal display unit 210, and an infusion / buzzer stop switch 222 In addition, an infusion start switch 223, a mute mode selection switch 224 (mute mode switch) for selecting a buzzer mute mode, and the like are provided.

  When the integrated amount switch 221 is pressed in a state where numerical data of “integrated amount (mL)” is displayed on the liquid crystal display unit 210, for example, the “scheduled amount (mL)” instead of the numerical data of “integrated amount (mL)” Switch to the state where the numerical data of “Amount (mL)” is displayed, and if it is pressed while the numerical data of “Scheduled amount (mL)” is displayed, it will be replaced with the numerical data of “Scheduled amount (mL)”. Switch to the state that displays the numerical data of “Integrated amount (mL)”.

The “integrated amount (mL)” is an integrated value of the “flow rate (mL / h)” from the start of the infusion, and is periodically calculated from the elapsed time from the start of the infusion and the “flow rate (mL / h)”. Update calculation is performed.
The infusion / buzzer stop switch 222 mutes the buzzer when pressed while the buzzer of the pump body 200 is sounding. When the buzzer is not sounding and is pressed during the infusion, the infusion operation is performed. It is a stitch that stops

The infusion start switch 223 is a switch for starting an infusion operation (pump operation), and the mute mode selection switch 224 is a switch for selecting a mode that does not sound a buzzer in advance.
The buzzer of the pump body 200 is sounded when an infusion is completed (when a predetermined amount of infusion is completed) or when an abnormality such as “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, “charge required” occurs. In addition to the display on the liquid crystal display unit 210, it notifies the completion of infusion and the occurrence of an abnormality.

In the present embodiment, a lamp 205 is provided on the upper surface of the main body 201 to notify the completion of infusion or the occurrence of an abnormality, and the lamp 205 is turned on even when the mute mode is selected. The completion of the infusion and the occurrence of an abnormality can be recognized around the pump body 200.
In the mute mode, it is possible to set the mode so that the lamp 205 is turned on when an abnormality occurs and the lamp 205 is not turned on when a buzzer is sounded.

As described above, the pump main body 200 of the present embodiment is not provided with an operation unit (operation button) for setting the predetermined amount (mL) and the flow rate (mL / h), and the predetermined amount (mL ) And flow rate (mL / h) are set based on command values transmitted from the setting terminal 100.
The command value is transmitted from the setting terminal 100 to the pump body 200 by short-range communication performed in a state where the pump body 200 and the setting terminal 100 are close to each other. As the communication means (short-range communication device), in this embodiment, short-range short-range wireless communication (for example, FeliCa (registered trademark) of Sony Corporation) used in a proximity non-contact IC card or the like is used.

  Specifically, a command value receiver (reader, short-distance communicator) 206 for performing the short-range wireless communication is provided on the upper surface of the pump main body 200, and the setting terminal 100 is connected to the communicator. When it is held over a short distance below several tens of centimeters 206, wireless communication is performed between the communicator on the setting terminal 100 side and the command value receiver 206, and the pump body 200 detects the setting terminal 100, The mutual authentication and data reading are performed, and the command values of the predetermined amount (mL) and the flow rate (mL / h) preset and stored using the operation button 120 in the setting terminal 100 are read into the pump body 200. It is.

  That is, even if the setting terminal 100 is operated in a state separated from the pump main body 200 to set / change the predetermined amount (mL) and the flow rate (mL / h), the setting / change is transferred to the pump main body 200. The setting / change result is stored in the memory of the setting terminal 100 without being transmitted immediately. And the communication between the pump main body 200 and the setting terminal 100 becomes possible by making the setting terminal 100 close to the pump main body 200 and being positioned in the communication area of the command value receiver 206. The scheduled amount (mL) and the flow rate (mL / h) stored in the memory of the setting terminal 100 are transmitted to the pump body 200. In other words, in order to cause the pump body 200 to read the scheduled amount (mL) and the flow rate (mL / h) set by the setting terminal 100, the setting terminal 100 is intentionally connected to the command value receiver 206 of the pump body 200. It needs to be close.

Here, when the setting terminal 100 is associated with the pump main body 200 on a one-to-one basis, and the setting terminal 100 corresponding to another pump main body 200 is brought closer, the planned amount (mL) and the flow rate (mL / h) ) Is not read, and the pump body 200 notifies the pump body 200 and the setting terminal 100 of different combinations by a buzzer or a lamp.
In addition, even when the corresponding setting terminal 100 is held over the command value receiver 206 of the pump body 200, the transmission / reception (reading of the command value of the scheduled amount (mL) and the flow rate (mL / h)) fails. The main body 200 may be notified by a buzzer or a lamp.
In order to clarify the combination of the pump body 200 and the setting terminal 100, a plate or the like having the same identification number may be attached to the pump body 200 and the setting terminal 100 that make a pair.

  When the pump body 200 reads the command values of the predetermined amount (mL) and the flow rate (mL / h) from the setting terminal 100 by the short-range wireless communication in a narrow area, the pump body 200 stores the read values in an internal memory, and the liquid crystal display When the start switch 223 is pushed, the flow rate (mL / h) command read from the setting terminal 100 is displayed. Start the infusion operation according to the value.

  Further, the pump body 200 calculates an integrated amount (mL) from the flow rate (mL / h) and the elapsed time from the start of the infusion operation (accumulated amount (mL / h) mL) is calculated, and the completion of the infusion is determined when the integrated amount (mL) reaches the predetermined amount (mL). When the infusion is completed, a completion display is displayed on the liquid crystal display unit 205 (flashing of the “complete” character). Further, the buzzer is sounded (and / or the lamp 214 is turned on), and the pump operation is shifted to the minimum flow rate operation.

  As the short-distance wireless communication, Bluetooth (registered trademark), infrared communication, or the like can be used in addition to Sony's Felica (registered trademark) used for the above-mentioned proximity type non-contact IC card.

The pump body 200 displays an abnormality occurrence on the liquid crystal display unit 205 and sounds a buzzer when it detects an abnormality of “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, or “requires charging”. At the same time, a signal indicating the occurrence of abnormality is wirelessly transmitted to the setting terminal 100.
For example, when the setting terminal 100 is placed on a nurse station or within a range in which a nurse carrying the setting terminal 100 moves in a normal working state, the abnormality occurrence signal is transmitted wirelessly. The maximum communication distance (radio wave intensity) is set so that wireless communication with the main body 200 can be performed. In other words, for short-range wireless communication that transmits the command value of the scheduled amount (mL) and flow rate (mL / h), a device for performing wireless communication over a wider area and with a longer maximum communication distance is set separately. The terminal 100 and the pump body 200 are provided respectively.

  Transmission of the command value of the scheduled amount (mL) and the flow rate (mL / h) from the setting terminal 100 to the pump body 200 is communication limited to the same room or the like (short-range wireless communication), and the pump body It is necessary to consciously bring the setting terminal 100 close to (or face) 200. On the other hand, the abnormal signal is transmitted from the pump body 200 to the setting terminal 100 when the setting terminal 100 moves away from the outside of the room where the pump body 200 is installed and the nurse carrying the setting terminal 100 carries it. It is set so that communication is possible even if the setting terminal 100 leaves the position where the pump body 200 cannot be directly viewed and the buzzer sound of the pump body 200 cannot be heard.

Accordingly, if the setting terminal 100 exists within a planned range, for example, within a hospital premises, within the same building, within the same ward, or on the same floor, an abnormal signal emitted from the pump body 200 is set by wide-range medium-range wireless communication. It is received by the terminal 100. In other words, when receiving the abnormal signal in the setting terminal 100, it is not necessary to be aware of the position and orientation of the setting terminal 100, and when an abnormal signal is transmitted from the pump body 200, this is immediately transmitted to the setting terminal 100 side. Received.
In radio communication of the abnormal signal, radio communication may be performed via a relay station when a radio wave is blocked by a wall and a necessary communication distance cannot be secured.

  When the pump main body 200 detects an abnormality of “bubble mixture”, “that is,” “flow rate abnormality”, “door open”, or “requires charging”, the pump main body 200 wirelessly transmits a signal notifying the occurrence of the abnormality to the setting terminal 100. Receiving the signal, the setting terminal 100 sounds a buzzer as described above and blinks the character display 111 of “abnormal pump”.

  The abnormality signal transmitted from the pump body 200 to the setting terminal 100 is a means for alerting the occurrence of abnormality by distinguishing “bubble mixing”, “that is,” “flow rate abnormality”, “door open”, “charge required”, etc. on the setting terminal 100 side ( For example, in the case of providing a character display by liquid crystal), a signal indicating the presence / absence of occurrence of each abnormality item may be used. On the setting terminal 100 side, “bubble mixture” “that is” “flow rate abnormality” “door open” In the case of generating an alarm without distinguishing between “required charging” and the like, a state in which any of the abnormal items has occurred and a state in which all of the abnormal items have not occurred are indicated on / off. It may be a signal.

FIG. 3 is a block diagram showing an internal configuration of the setting terminal 100. In addition to the liquid crystal display unit (display device) 110 and operation buttons 120, a processing device (calculation unit) 130, a memory 140, an alarm receiver (wide area) A medium-range wireless communication device, alarm receiving unit) 150, a buzzer (alarm sound generating unit) 160, a command value transmitter (narrow area short-range wireless communication device) 170, and the like are provided.
The memory 140 is preferably a non-volatile rewritable memory (EEPROM).

When the scheduled amount (mL) and the flow rate (mL / h) are set / changed by operating the operation button 120, the processing device 130 displays the result on the liquid crystal display unit (display device) 110. And stored in the memory 140.
The command values of the scheduled amount (mL) and the flow rate (mL / h) stored in the memory 140 are executed using the command value transmitter 170 in a state where the setting terminal 100 is brought close to the pump body 200. It is transmitted to the pump body 200 side by short-range wireless communication.

In addition, a radio signal notifying the occurrence of an abnormality transmitted from the pump body 200 side is received by the alarm receiver 150. When the radio signal notifying the occurrence of an abnormality is received, the processing device 130 displays the liquid crystal display unit (display). The device 110 flashes the pump abnormality character display 111 and sounds the buzzer 160 to warn of the occurrence of the abnormality.
Further, the processing device 130 determines the scheduled completion time of the infusion, and blinks the character display 117 of “infusion completion” on the liquid crystal display unit (display device) 110 when the scheduled completion time is reached. Sound 160.

FIG. 4 is a block diagram showing an internal configuration of the pump main body 200. The liquid crystal display unit (display device) 210, operation buttons 220, command value receiver (narrow area short-range wireless communication device) 206, lamp 205, pump A motor 270, a processing device 230, a memory 240, an alarm transmitter (wide-area medium-range wireless communication device, alarm transmitter) 250, a buzzer 260 (alarm sound generator), and the like are provided.
The memory 240 is preferably a nonvolatile rewritable memory (EEPROM).

When the setting terminal 100 (command value transmitter 170, non-contact communication medium) is positioned in a nearby communication area, the command value receiver (reader) 206 receives a predetermined amount (mL) from the setting terminal 100 side. Read the flow rate (mL / h) command value.
The command value of the predetermined amount (mL) and the flow rate (mL / h) read by the command value receiver (reader) 206 is stored in the memory 240 via the processing device 230, and the processing device 230 reads the command value. The command value of the scheduled amount (mL) and the flow rate (mL / h) is displayed on the liquid crystal display unit (display device) 210.

Further, the processing device 230 performs an operation setting of the main body (pump unit) 201 according to the command value of the flow rate (mL / h), and when the start switch 223 is pressed, the command value of the flow rate (mL / h). The pump operation corresponding to is started.
Further, after the start of infusion (start of pump operation), the processing device 230 calculates the integrated amount based on the command value of the flow rate (mL / h), and if there is a display request for the integrated amount, the integrated amount of the calculation result is displayed on the liquid crystal display. When the integrated amount reaches a predetermined amount, the infusion completion is displayed on the liquid crystal display unit (display device) 210 and the buzzer 260 and / or the lamp 205 is operated.

  Further, the processing device 230 determines the presence / absence of an abnormality (such as mixing of bubbles) from various sensor signals. If an abnormality occurs, the processing device 230 displays an abnormal item on the liquid crystal display unit (display device) 210 and the buzzer 260 and / or Alternatively, the lamp 205 is operated, and a signal indicating the occurrence of an abnormality is wirelessly transmitted to the alarm receiver 150 on the setting terminal 100 side via the alarm transmitter 250.

  When an infusion pump comprising the setting terminal 100 and the pump body 200 having the above-described configuration is used for administration of a nutrient solution or the like to a patient in a hospital, for example, the pump body 200 is located at a place (patient room or treatment room) where the administration is actually performed. Although installed, the setting terminal 100 can be carried independently with respect to the pump body 200, and the command values of the scheduled amount (mL) and the flow rate (mL / h) set by the setting terminal 100 are It is stored in the memory 140 of the setting terminal 100.

  Therefore, the setting of the scheduled amount (mL) and the flow rate (mL / h) using the setting terminal 100 does not need to be performed in the vicinity of the pump main body 200 and does not need to be performed immediately before actually starting the infusion. For example, a doctor or a nurse can operate the setting terminal 100 and set command values for a predetermined amount (mL) and a flow rate (mL / h) in advance in an examination room or a nurse station.

And when actually administering a nutrient etc. with respect to a patient, the nurse carries the setting terminal 100 which set the command value of scheduled amount (mL) and flow volume (mL / h), It moves to the place where the pump body 200 is installed (patient room, treatment room, etc.).
The nurse who went to the place where the pump body 200 is installed turns on the pump body 200, prepares and primes the infusion set, and attaches the infusion tube to the pump body 200. By holding the command value receiver (reader) 206 of the main body 200, the command values of the predetermined amount (mL) and the flow rate (mL / h) preset and stored on the setting terminal 100 side are read into the pump main body 200 side. Make it.

The pump body 200 that has read the command values of the predetermined amount (mL) and the flow rate (mL / h) from the setting terminal 100 side performs infusion operation setting and liquid crystal display according to the read values.
The nurse confirms that the command values of the scheduled amount (mL) and the flow rate (mL / h) are read and set to the pump main body 200 side by the display on the liquid crystal display unit 210 of the pump main body 200, and then The patient is punctured with a venous needle and the start switch 223 is pressed to start the infusion operation.

The setting terminal 100 calculates the scheduled completion time based on the determination of the start of the infusion operation, and displays the calculated estimated completion time. The determination of the start of the infusion operation is performed at a short distance from the pump body 200. The point in time when wireless communication is performed may be regarded as the start of the infusion operation, or from the pump body 200 to the setting terminal 100 side by short-range wireless communication in which the scheduled volume (mL) and the flow rate (mL / h) are transmitted and received. Can be configured to transmit a signal indicating the start of the infusion operation.
The setting terminal 100 is provided with a button (time measurement start command switch) for designating the start time of the infusion (instructing the start of counting the elapsed time after the start of the infusion operation). By operating the button of the setting terminal 100 immediately after pressing 223, the setting terminal 100 can recognize the start of infusion.

  After starting the infusion operation, the nurse leaves the pump body 200 and returns to the nurse station or moves to another hospital room so that the pump body 200 cannot be monitored directly. However, if the user moves with the setting terminal 100 or places the setting terminal 100 in the nurse station, if any abnormality occurs in the pump body 200, the setting terminal 100 that is carried or placed in the nurse station Since an abnormal signal transmitted from the pump main body 200 is received and warned, even if the pump main body 200 is away from the pump main body 200, it is known that an abnormality has occurred in the pump main body 200 and goes to the hospital room where the pump main body 200 is placed. Treatment can be performed.

Moreover, since the completion time (remaining time) of the infusion operation is displayed on the setting terminal 100, the nurse can determine the timing to visit the hospital room based on the display, and can perform efficient work.
In addition, when the start switch 223 is not pushed within a predetermined time after the command values of the scheduled amount (mL) and the flow rate (mL / h) set by the setting terminal 100 are read into the pump body 200, the scheduled amount (mL ) And the flow rate (mL / h) command values are reset to the initial state where the command values are not set, and the command of the scheduled amount (mL) and flow rate (mL / h) set on the setting terminal 100 side in the pump main body 200 again. It may be configured to read the value.

As described above, in this embodiment, unless the setting terminal 100 is brought close to the corresponding pump main body 200, the scheduled amount (mL) and the flow rate (mL / h) in the pump main body 200 are not set. In addition, the planned volume (mL) and the flow rate (mL / h) can be set after checking the infusion bag and the like, and it is possible to avoid inadvertently setting the infusion operation in the pump body 200.
For example, in the so-called remote operation type in which the operation button 120 of the setting terminal 100 is pressed wirelessly and the setting and operation corresponding to the button operation is performed on the pump body 200 side, a plurality of pump bodies 200 are installed. In some cases, the setting operation is performed while the correspondence between the pump main body 200 and the setting terminal 100 is unclear, and the scheduled amount (mL) and the flow rate (mL / h) may be set incorrectly.

On the other hand, in the act of holding the setting terminal 100 over the pump main body 200 (making it close to the pump main body 200), the operation of the setting terminal 100 and the pump main body 200 is performed with a clear consciousness. The possibility that (mL / h) is erroneously set can be reduced.
In addition, on the pump body 200 side, the scheduled amount (mL) and the flow rate (mL / h) cannot be set / changed. For example, after setting the pump operation by the setting terminal 100, an illegal setting change is made. You can avoid that.

  Furthermore, for example, if the doctor performs the setting operation of the scheduled amount (mL) and the flow rate (mL / h) at the setting terminal 100 according to his / her prescription, the nurse can bring the setting terminal 100 to the pump body 200 as it is. Since the setting operation can be completed, the nurse does not need to set and change the scheduled volume (mL) and flow rate (mL / h) by operating the operation buttons according to the doctor's prescription. It is possible to prevent setting errors due to reading mistakes or incorrect hearing of verbal instructions.

In addition, the occurrence of an abnormality in the pump main body 200 is wirelessly transmitted to the setting terminal 100, and an abnormality display and a buzzer are sounded. Therefore, even when away from the pump main body 200, the abnormality is recognized by the setting terminal 100. , Can respond quickly.
Further, if the buzzer 260 in the pump body 200 is set in the mute mode, the nurse who is waiting at the nurse station, for example, can avoid the disturbing patient's sleep due to the buzzer sound at night. The occurrence of abnormality in the pump body 200 can be known.

In the above-described embodiment, the pump body 200 is not provided with an operation button for setting / changing the scheduled amount (mL) and the flow rate (mL / h). mL) and flow rate (mL / h) operation buttons are provided for setting / changing, and a predetermined amount (mL) and flow rate (mL / h) set by operating the operation buttons are stored in a built-in memory (storage unit). ) May be stored.
In this case, it is possible to set and change the scheduled amount (mL) and the flow rate (mL / h) by a button operation on the pump body 200 side, and when the setting terminal 100 is brought closer, the setting terminal 100 sets the setting amount. The command value of the predetermined amount (mL) and the flow rate (mL / h) can be read.

Here, if priority is given to the command value of the scheduled amount (mL) and the flow rate (mL / h) set in the setting terminal 100, the planned amount (mL) and the flow rate ( Even if the setting / change of (mL / h) is performed, if command values for the planned volume (mL) and flow rate (mL / h) different from those are read from the setting terminal 100, the setting on the setting terminal 100 side The pump operation can be performed according to
Therefore, even when the setting terminal 100 is not provided, the infusion can be started by setting the scheduled amount (mL) and the flow rate (mL / h) by operating the pump body 200, while the scheduled amount (by the operation of the pump body 200 ( mL) and flow rate (mL / h) setting errors can be corrected from the setting terminal 100 by a command of the predetermined amount (mL) and flow rate (mL / h).

Further, the scheduled amount (mL) and the flow rate (mL / h) are set and changed by a button operation on the pump body 200 side, and the scheduled amount (mL) and the flow rate (mL / h) set on the setting terminal 100 side are set. ) Is read, and when the two values match, the start of the infusion operation is permitted.
With the above configuration, if at least one of the pump main body 200 side and the setting terminal 100 side has a setting error of the predetermined amount (mL) and the flow rate (mL / h), the infusion operation cannot be started, and thus a setting error occurs. Therefore, it is necessary to confirm the scheduled amount (mL) and the flow rate (mL / h), and it is possible to prevent infusion at the wrong scheduled amount (mL) and flow rate (mL / h).

In the embodiment shown in FIG. 2, the command value receiver (reader) 206 for performing short-range wireless communication with the setting terminal 100 is installed on the upper surface of the pump body 200. As shown in FIG. In addition, the receiver (reader) 206 is provided on the side surface of the pump body 200, and the setting terminal holder (pocket, mounting portion) that accommodates and supports the setting terminal 100 at a position where transmission and reception with the receiver 206 is possible. ) 231 is provided, and short-range wireless communication can be performed between the setting terminal 100 accommodated in the setting terminal holder 231 and the pump body 200.
The setting terminal holder 231 has an opening for inserting the setting terminal 100 in the upper part, and has a pocket shape that holds the setting terminal 100 in parallel with the side surface of the pump body 200.

  When the setting terminal holder 231 is provided, the nurse inserts the setting terminal 100 into the setting terminal holder (pocket) 231 when approaching the pump body 200 in order to start the infusion operation, and the planned amount (mL) and flow rate If the setting terminal 100 is removed from the setting terminal holder 231 after (mL / h) is read and the start switch 223 is pressed, short-range wireless communication between the setting terminal 100 and the pump main body 200 is performed. The setting terminal 100 can obtain the infusion operation start signal from the pump main body 200 side by short-range wireless communication, and the calculation accuracy of the scheduled completion time is improved.

Here, before the start switch 223 is pressed, when the setting terminal 100 is pulled out from the setting terminal holder 231 and short-range wireless communication is interrupted, the pump body 200 gives a warning by a buzzer or the like as an abnormality, and once reads It is possible to cancel the command of the scheduled amount (mL) and the flow rate (mL / h).
Note that the removal of the setting terminal 100 from the setting terminal holder 231 can be determined by the short-range wireless communication being interrupted, and can also be determined by turning on / off a limit switch provided at the bottom of the setting terminal holder 231 or the like. .

  Further, the infusion operation can be started based on the setting terminal 100 being removed from the setting terminal holder 231. For example, after the start switch 223 is pressed, the setting terminal 100 is removed from the setting terminal holder 231. If the infusion operation is started, forgetting to remove the setting terminal 100 can be prevented. In this case, when the start switch 223 is pressed, it is preferable to perform display or voice guidance for prompting the setting terminal 100 to be extracted.

If the nurse carries the setting terminal 100 or places the setting terminal 100 in a room where there is a high possibility of having a nurse such as a nurse station, the abnormality of the pump body 200 is notified to the setting terminal 100 wirelessly. When the setting terminal 100 makes a buzzer or the like, even if the setting terminal 100 is not near the pump body 200, the nurse can notice the occurrence of the abnormality, but if the setting terminal 100 is left in the setting terminal holder 231, The above actions / effects cannot be obtained.
Therefore, by removing the setting terminal 100 from the setting terminal holder 231 as a condition for starting the infusion operation, the occurrence of misplacement can be prevented and the nurse can recognize the abnormality of the pump body 200 via the setting terminal 100. To.

  Further, in the configuration in which the setting terminal holder 231 is provided in the pump body 200, as shown in FIG. 6, the start switch 223 is not provided in the pump body 200, but the start switch 124 is provided in the setting terminal 100 as shown in FIG. When the start switch 124 of the setting terminal 100 is pressed in a short-distance wireless communication establishment state where the setting terminal 100 is inserted into the setting terminal holder 231, a start command signal based on the pressing of the start switch 124 is It can be configured such that it is wirelessly transmitted to the pump body 200 side by short-range wireless communication, and the pump body 200 starts the infusion operation.

In this case, the pump body 200 alone cannot start the infusion operation, the setting terminal 100 is inserted into the setting terminal holder 231, and the pump body 200 sets the command values for the scheduled amount (mL) and the flow rate (mL / h). The infusion operation is started by reading and pressing the start switch 124 of the setting terminal 100.
Therefore, if the nurse carries the setting terminal 100, the infusion operation can be avoided regardless of the instruction / operation of the nurse, the malfunction of the infusion pump can be prevented, and the setting terminal 100 can be started. Since the switch 124 does not start the pump operation of the pump main body 200 if the short-range wireless communication with the pump main body 200 is not established, the pump operation is not inadvertently started. .

  When the setting terminal 100 is held by the setting terminal holder 231, the operation button 120 (up / down switch 121) of the setting terminal 100 is operated in the holding state, so that the pump is linked to the operation. It can be configured such that the setting of the predetermined amount (mL) and the flow rate (mL / h) on the main body 200 side is switched.

By the way, in the said embodiment, transmission to the pump main body 200 side of the command value of the scheduled amount (mL) and flow volume (mL / h) set by the setting terminal 100 side is carried out, such as FeliCa (registered trademark) of Sony Corporation. Although the short range wireless communication is performed, the command value can be transmitted and received by wired communication via a detachable connector.
FIG. 8 is a perspective view showing a pump main body 200 that reads a command value from the setting terminal 100 side by the wired communication. The pump main body 200 shown in FIG. 8 is different from the pump main body 200 shown in FIG. The only difference is that a setting terminal mounting unit 280 provided with a connector is provided in place of the communication device (reader) 206. Common parts other than the setting terminal mounting unit 280 are denoted by the same reference numerals as in FIG. Detailed description is omitted.

  A concave portion 281 constituting the setting terminal mounting portion 280 is formed on the upper surface of the pump main body 200 (main body portion 201) shown in FIG. 8, and the depth D of the concave portion 281 is substantially equal to the thickness T of the setting terminal 100. Similarly, the size of the region surrounded by the inner peripheral wall of the recess 281 is slightly larger than the outer shape of the setting terminal 100, and the setting terminal 100 is dropped into the recess 281 in a substantially horizontal state.

FIG. 9 is an enlarged perspective view showing the top surface of the pump main body 200 (main body portion 201) provided with the concave portion 281. The bottom surface 282 of the concave portion 281 is electrically connected with a connector provided on the setting terminal 100 side. Further, a connector 283 to be connected is provided, and a lock member 285 for locking the setting terminal 100 in the retracted state is provided on the opposite surfaces of the inner peripheral wall 284 of the recess 281 to the setting terminal 100. Are provided at four locations in total.
The lock member 285 is supported so as to freely advance and retract between a position protruding from the inner peripheral wall 284 as shown in FIG. 9 and a position where the tip of the lock member 285 is substantially flush with the inner peripheral wall 284 and does not protrude from the inner peripheral wall 284. In addition, it is biased in a direction protruding from the inner peripheral wall 284 by an elastic body (such as a spring) not shown.

An eject button 286 is provided on the upper surface of the pump main body 200 (main body portion 201) near the recess 281 to retract the lock member 285 to the inner peripheral wall 284 side so as not to protrude from the inner peripheral wall 284. Yes.
On the other hand, the peripheral wall 100a of the setting terminal 100 is provided with four fitting holes 180 into which the lock member 285 is inserted in accordance with the position of the lock member 285. Also, as shown in FIG. A connector 190 that fits and is electrically connected to the connector 283 on the back surface 100 b of 100 is provided in accordance with the position of the connector 283 on the bottom surface 282.

When the setting terminal 100 is pushed into the setting terminal mounting portion 280 with the surface 100c on which the liquid crystal display unit 110 and the operation button (operation unit) 120 are provided facing upward, the lock member 285 is pressed by the peripheral wall 100a of the setting terminal 100. Thus, the locking member 285 is retracted, and when the setting terminal 100 is further pushed in, the connector 190 on the setting terminal 100 side and the connector 283 on the pump body 200 side are fitted.
When the connector 190 and the connector 283 are pushed in until the desired fitting state is reached, the positions of the lock member 285 and the fitting hole 180 match in the depth direction of the recess 281, as described above. A lock member 285 urged in a direction protruding from the inner peripheral wall 284 by an elastic body (such as a spring) is fitted into the fitting hole 180, and the setting terminal 100 is locked to the setting terminal mounting portion 280.

In the locked state, the connector 190 on the setting terminal 100 side and the connector 283 on the pump body 200 side are fitted and electrically connected, and the setting terminal 100 and the pump body 200 are wired via the connectors 190 and 283. It becomes possible to communicate with each other.
On the other hand, when the setting terminal 100 is removed from the setting terminal mounting portion 280 and the connector 190 and the connector 283 are electrically disconnected, the lock member 285 is pressed by pressing the eject button 286. Is retracted and removed from the fitting hole 180, and the setting terminal 100 is pulled upward in this state, so that the connector 190 and the connector 283 are disengaged, and the wired communication path is cut off.

  A plate elastically biased upward is provided on the bottom surface 282 of the recess 281. When the setting terminal 100 is attached, the setting terminal 100 is pushed down against the elastic biasing force. If locked, when the eject button 286 is pressed to retract the lock member 285, the setting terminal 100 is moved upward from the recess 281 with a force that lifts the plate upward by elastic return force. The setting terminal 100 can be easily removed.

FIG. 11 is a block diagram showing an internal configuration of the setting terminal 100 having the connector 190. Instead of the short-range wireless communication communicator 170 shown in FIG. A wired communication device 191 for transmitting a signal to the pump body 200 side and receiving a signal sent from the pump body 200 side is provided.
On the other hand, FIG. 12 is a block diagram showing an internal configuration of the pump body 200 provided with the connector 283. In place of the short-range wireless communication communicator (reader) 206 shown in FIG. A wired communication device 289 for transmitting a signal to the setting terminal 100 via the connector 283 and receiving a signal sent from the setting terminal 100 is provided.

Then, when the connector 190 on the setting terminal 100 side and the connector 283 on the pump body 200 side are fitted and electrically connected, signals are transmitted and received between the setting terminal 100 and the pump body 200 by wired communication. It becomes possible.
In the configuration including the above-described connectors 190 and 283, the command values are set by operating the operation buttons 120 of the setting terminal 100 in advance to set the command values for the scheduled amount (mL) and the flow rate (mL / h). The setting terminal 100 is carried in the room where the pump body 200 is placed.

When the setting terminal 100 is mounted on the setting terminal mounting portion 280 of the pump main body 200 that is turned on, the connector 190 and the connector 283 are fitted and electrically connected, and wired via the connectors 190 and 283. Since communication becomes possible, the command values of the scheduled amount (mL) and the flow rate (mL / h) are transmitted from the setting terminal 100 side to the pump body 200 side.
The pump main body 200 that has transmitted the command value of the predetermined amount (mL) and the flow rate (mL / h) performs setting to perform the infusion operation corresponding to the command value, and starts the infusion operation when the start switch 223 is pressed. Let

When the infusion operation is started by operating the start switch 223, a signal indicating the start of the infusion operation is transmitted from the pump body 200 side to the setting terminal 100 side via the connectors 190 and 283, and the infusion operation is performed. Upon receiving the start signal, the setting terminal 100 calculates the scheduled time for completion of the infusion from the current time and the stored scheduled volume (mL) and flow rate (mL / h) command values, and the calculation result Is displayed on the liquid crystal display unit 110.
The scheduled time for completion of the infusion is continued even after the setting terminal 100 is removed from the setting terminal mounting part 280 of the pump body 200, and the scheduled time for completion of the infusion is confirmed from the setting terminal 100 separated from the pump body 200. Can do.

Even when the pump main body 200 and the setting terminal 100 are not connected via the connectors 190 and 283, the abnormality signal detected by the pump main body 200 is transmitted to the setting terminal 100 side by radio, and the abnormal signal is displayed. Based on this, the setting terminal 100 sounds a buzzer.
Therefore, a nurse who carries the setting terminal 100 or a nurse who packs in the nurse station where the setting terminal 100 is placed, in other words, a nurse who is away from the pump body 200 generates an abnormality. It is possible to notice immediately and rush to the hospital room where the corresponding pump main body 200 is placed to perform necessary processing.

  Similarly to the case where the setting terminal holder 231 is provided, the pump body 200 is not provided with the start switch 223, and as shown in FIG. 13, a start switch 124 is provided on the setting terminal 100 side, and the setting terminal 100 is set as the setting terminal. When mounted on the mounting unit 280, the command values of the predetermined amount (mL) and the flow rate (mL / h) set in advance on the setting terminal 100 are communicated to the pump body 200 side by wire, and the communication is normally performed. In this state, when the start switch 124 of the setting terminal 100 is pressed, the infusion operation can be started.

Further, by providing a connector 283 at the end of the communication line extending from the pump main body 200 and connecting the connector 190 of the setting terminal 100 to the connector 283, wired communication between the setting terminal 100 and the pump main body 200 is possible. The communication path to be connected can be connected.
However, the communication line extending from the pump main body 200 has a length of several meters at the maximum and cannot be connected outside the hospital room where the pump main body 200 is provided, for example, in the vicinity of the pump main body 200 (for example, the same hospital room). Then, the setting terminal 100 can be connected.

That is, for example, the pump main body 200 and the setting terminal 100 are not connected to a LAN (local communication network) constructed in a hospital building, but the pump main body 200 and the setting terminal 100 are wired to communicate at a short distance of one to one.
Even when the wired communication is performed, the command values of the scheduled amount (mL) and the flow rate (mL / h) can be set and stored in the setting terminal 100 in advance, but the pump body 200 is actually set according to the setting. In order to operate, it is necessary to carry the setting terminal 100 to the vicinity of the pump body 200, and while confirming the correspondence of the patient, the infusion bag, etc., the planned amount (mL) and the flow rate (mL / h) in the pump body 200 Can be set.

  Moreover, since the data stored in advance in the setting terminal 100 is transferred to the pump main body 200, the scheduled amount (mL) and the flow rate (mL / h) in the pump main body 200 are set. The predetermined amount (mL) and flow rate (mL / h) designated by operating 100 can be set in the pump body 200 as they are, and erroneous setting of the predetermined amount (mL) and flow rate (mL / h) can be avoided.

  In addition, when the command value of the scheduled amount (mL) and the flow rate (mL / h) stored in advance in the setting terminal 100 is transmitted to the pump main body 200 by short-range wireless / wired communication, the response of the infusion bag or the patient In order to be able to confirm the relationship, the function of inputting and storing the identification information of the infusion bag and the patient and the identification code (bar code, two-dimensional code, etc.) attached to the infusion bag, the patient or the patient's bed, etc. are read. When the setting terminal 100 is provided with a reader, and the infusion bag or patient identification code read by the reader matches the infusion bag or patient identification information stored in the setting terminal 100 in advance, the expected amount (ML) and flow rate (mL / h) command values are allowed to be transmitted to the pump body 200. If they do not match, the command values are prohibited from being transmitted and a warning is given with a buzzer or the like. It can be configured.

With the above configuration, if the planned volume (mL) and flow rate (mL / h), infusion bag, and patient combination are specified in advance, the infusion bag and the planned volume (mL ) · Infusion can be avoided at a flow rate (mL / h).

  In this case, for example, when the external receiver is connected to the pump main body 200, the pump main body 200 operates with the command values of the scheduled amount (mL) and the flow rate (mL / h) read from the setting terminal 100. When the external receiver is not connected to the pump main body 200, the pump main body 200 is operated at a predetermined amount (mL) and a flow rate (mL / h) commanded by an operation unit provided on the pump main body 200. Can be configured.

In addition, the alarm receiver 150 that receives the abnormal signal (alarm signal) from the pump main body 200 in the setting terminal 100 periodically determines the radio wave intensity from the pump main body 200 side, and the radio wave intensity is improved in communication stability. A buzzer can be sounded when the signal level drops so that the signal intensity decreases, and a warning can be given for a decrease in radio field intensity.
With such a configuration, the nurse can recognize that there is a possibility that reception of an abnormal signal may be hindered due to radio wave interference or movement of the pump body 200, and the abnormal signal does not reach the setting terminal 100 due to poor communication. It is possible to prevent the abnormal state of the pump body 200 from being left unattended.

In addition, when the setting terminal 100 and / or the pump body 200 is provided with a fingerprint authentication device, and the fingerprint authentication device reads a pre-registered fingerprint, that is, it is determined that the user is a pre-registered doctor or nurse. Only when the setting terminal 100 sets / changes the scheduled amount (mL) and the flow rate (mL / h) and starts the operation of the pump main body 200.
Further, when the pump body 200 is provided with a command value receiver (reader) 206, the command value receiver (reader) 206 can also read the personal authentication IC card (ID card), and the nurse can carry it individually. When the personal authentication IC card is read by the command value receiver (reader) 206 and identified as a registered nurse, transmission / reception with the setting terminal 100 and start of pump operation are started. Can be configured to allow.

As described above, if the setting terminal 100 and / or the pump main body 200 is provided with a personal authentication device, only a registered nurse or doctor can perform an operation, and an incorrect setting of the operation of the infusion pump can be performed. It can be prevented more reliably.
Furthermore, the operation history of the setting terminal 100 and / or the pump main body 200 can be stored in each memory, and when performing personal authentication using a fingerprint or a personal authentication IC card, information on the operated doctor or nurse is included. The operation history can be saved correspondingly.
