The situation where the infusion should be stopped is that various alarms such as a bubble mixing alarm, an upstream blockage alarm, a downstream blockage alarm, etc. are issued, the infusion completion is notified and the user performs a stop operation, For example, there may be a case where an operation for temporarily stopping the infusion is performed.
In the case of the present embodiment, the infusion stop determination unit 76 is in a situation where the infusion should be stopped based on the operation of the operation unit 31 and the detection results of the bubble sensor 22, the upstream blockage sensor 23, and the downstream blockage sensor 24. It is determined whether or not.

  The switching operation determination unit 77 determines whether or not a switching operation for performing a prescription different from that at the start of the infusion is performed before the infusion is completed. In the present embodiment, the switching operation determination unit 77 determines whether or not a switching operation has been performed based on the determination results of the infusion completion determination unit 75 and the infusion stop determination unit 76 and the operation of the operation unit 31. .

The procedure for recording the injection note log and the progress log in the medical pump 1 will be described.
First, a process until the infusion performed is completed will be described based on FIG.
First, when a power-on operation is performed at the operation unit 31, the control unit 70 controls the power supply unit 40 to start power supply and turns on the power (step S1). Next, when the inspection mode is selected by the operation unit 31, the control unit 70 performs the inspection according to the selected inspection mode (step S2). Details of the inspection mode will be described later.

  Thereafter, the infusion setting unit 71 sets the infusion flow rate and the planned amount based on the operation of the operation unit 31 or based on the injection note information received from the external terminal, and stores the set flow rate and the planned amount. It records in the part 60 (step S3). Next, the infusion start determination unit 72 determines whether or not an infusion start operation has been performed by the operation unit 31 (step S4). The process of step S3 is repeated until an infusion start operation is performed.

  If it is determined in step S3 that an infusion start operation has been performed, the infusion history recording unit 74 records the infusion start on the injection note log (step S5), and the pump drive unit 73 drives the pump unit 21 to deliver the infusion. Start (step S6). Further, the infusion history recording unit 74 periodically records a progress log (step S7). In the case of this embodiment, the infusion history recording unit 74 records a progress log every 30 minutes.

  Thereafter, the infusion completion determination unit 75 determines whether the infusion is completed (step S8). When it is determined in step S8 that the infusion has not been completed, the infusion stoppage determination unit 76 determines whether or not the infusion should be stopped (step S9). The situation where the infusion should be stopped corresponds to a case where various alarms are issued or a case where the user performs an operation for temporarily stopping the infusion for some reason.

If it is determined in step S9 that the infusion should not be stopped, the control unit 70 returns to step S7 and continues the process. While the processing from step S7 to step S9 is being performed, the started infusion is continued according to the injection note.
If it is determined in step S9 that the infusion should be stopped, the pump drive unit 73 stops driving the pump unit 21 and stops the infusion (step S10). Next, the infusion start determination unit 72 determines whether or not an infusion start operation has been performed (step S11). When it is determined in step S11 that the infusion start operation has been performed, the control unit 70 returns to step S6 and continues the process.

  On the other hand, when it is determined in step S8 that the infusion is completed, the infusion history recording unit 74 records the end in the injection note log (step S12). At this time, the control unit 70 causes the display unit 32 to display completion of the infusion by a method such as lamp blinking, and causes the sound output unit 50 to output a notification sound. Even if the infusion is completed, in order to prevent thrombus, the infusion stop determination unit 76 determines whether or not the infusion should be stopped (step S13), and the pump drive unit 73 stops the infusion. The pump unit 21 is driven until the situation should occur, and the infusion is continued at a low flow rate (step S14). The situation where the infusion should be stopped here mainly corresponds to a case where the user performs a stop operation using the operation unit 31. And if it determines with it being in the condition which should stop infusion, the pump drive part 73 will stop the drive of the pump part 21, and will stop infusion (step S15). Next, the control unit 70 determines whether or not a power-off operation has been performed by the operation unit 31 (step S16). If it is determined in step S16 that the power-off operation has been performed, the control unit 70 cuts off the power supply of the power unit 40 and turns off the power (step S17), and it is determined that the power-off operation has not been performed. Then, it returns to step S3 and continues a process.

  FIG. 3 shows an injection note log and a progress log when the infusion is completed. From the injection note log, it can be seen that recording started at 12:30 on November 25, 2014 (ie, infusion started) and ended at 22:45 on the same day. Further, the progress log shows that the downstream blockage alarm was issued at 13:45 on the same day, the infusion stopped temporarily, and the infusion was resumed at 13:58 on the same day.

  Next, based on FIG. 6, the process when the switching operation which implements prescription different from the start time after the start of infusion is performed will be described.

  If it is determined in step S11 (FIG. 5) that the infusion start operation has not been performed, the switching operation determination unit 77 determines whether a power-off operation has been performed (step S18). Thereby, the switching operation determination part 77 determines whether switching operation was performed before completion of infusion. If it is determined in step S18 that the power-off operation has been performed, the infusion history recording unit 74 records an end record in the injection note log (step S19). Thereafter, the process of step S17 is performed, and the power is turned off.

  If it is determined in step S18 that the power-off operation has not been performed, the switching operation determination unit 77 determines whether or not the switching operation has been performed by determining whether or not the integrated amount of infusion has been initialized. Is determined (step S20). If it is determined in step S20 that the infusion start operation has not been performed, the switching operation determination unit 77 further determines whether or not the switching operation has been performed by determining whether or not the infusion flow rate or scheduled amount has been changed. Is determined (step S21). When it is determined in step S21 that the flow rate or the scheduled amount has not been changed, the control unit 70 returns to step S11 and continues the processing.

  On the other hand, if it is determined in step S20 that the integrated amount has been initialized, or if it is determined in step S21 that the flow rate or the scheduled amount has been changed, the infusion history recording unit 74 records the end of the injection note log ( Step S22). Thereafter, the control unit 70 returns to step S4 and continues the processing.

  FIG. 7 shows an injection note log and a progress log when the started infusion is stopped halfway. From the injection note log, it can be seen that the infusion was started at 12:30 on November 26, 2014 and stopped at 20:32 on the same day. Further, from the progress log, it can be seen that the upstream blockage alarm was issued at 14:15 on the same day, the infusion was temporarily stopped, and the infusion was resumed at 14:22 on the same day.

[Inspection mode]
The inspection mode is a mode that supports the inspection of the medical pump 1, and a bubble inspection mode, an upstream blockage inspection mode, and a downstream blockage inspection mode are prepared.
First, the bubble inspection mode will be described.
Conventionally, the user has flowed about 10 mm of bubbles into the infusion tube 2 during the infusion, and has confirmed whether or not a bubble mixing alarm is generated.

  On the other hand, in the medical pump 1, when the user sets an empty infusion tube 2 and performs an infusion start operation in a state where the bubble inspection mode is selected, the control unit 70 detects the detected value of the bubble sensor 22. And the presence / absence of air bubble mixing is displayed on the display unit 32. Thereafter, when the user sets the infusion tube 2 primed with water and performs an infusion start operation, the control unit 70 acquires the detection value of the bubble sensor 22 and displays the presence / absence of bubbles in the display unit 32. In this way, if the bubble check mode is used, it is not necessary to check whether an alarm is actually generated by flowing bubbles, so that it is possible to check more easily than before, and to reduce the check time. .

Next, the upstream blockage inspection mode will be described.
Conventionally, after a user manually sets inspection parameters (for example, a planned volume of 200 mL, a flow rate of 120 mL / h), an infusion start operation is performed in a state where the infusion tube 2 is closed upstream of the pump unit 21. The time until the occurrence of an upstream blockage alarm measured with a stopwatch was confirmed to be within a predetermined range.

  On the other hand, in the medical pump 1, when the upstream blockage inspection mode is selected, the control unit 70 automatically sets parameters for the upstream blockage inspection. When the user closes the infusion tube 2 on the upstream side of the pump unit 21 and performs an infusion start operation, the control unit 70 calculates the time until the upstream blockage alarm is generated, and whether this time is within a predetermined time. Whether or not there is an upstream blockage is displayed on the display unit 32. As described above, parameter setting is automated, and it is not necessary to operate the stopwatch. Therefore, inspection can be performed more easily than before, and inspection time can be shortened.

Next, the downstream blockage inspection mode will be described.
Conventionally, after the user manually sets inspection parameters (for example, a predetermined amount of 200 mL, a flow rate of 120 mL / h) and a predetermined downstream blockage detection set value, the infusion tube 2 is provided downstream of the pump unit 21. The infusion start operation was performed in a state where the device was occluded, and it was confirmed whether the time until the occurrence of the downstream occlusion alarm measured by the stopwatch was within a predetermined range. In this case, after the downstream blockage inspection, it is necessary to return the downstream blockage detection setting value to the original setting at the time of use, but this may be forgotten.

  In contrast, in the medical pump 1, when the downstream blockage inspection mode is selected, the control unit 70 automatically sets the parameters for downstream blockage inspection and the downstream blockage detection set value. When the user closes the infusion tube 2 downstream of the pump unit 21 and performs an infusion start operation, the control unit 70 calculates the time until the downstream blockage alarm is generated, and whether this time is within a predetermined time. It is determined whether or not there is a downstream blockage on the display unit 32. Thereafter, when the user cancels the downstream blockage inspection mode, the control unit 70 automatically returns the downstream blockage detection setting value to the original setting. For this reason, it is possible to prevent forgetting to return the downstream blockage detection setting value to the original value at the time of use. In addition, since parameter setting is automated and it is no longer necessary to operate the stopwatch, inspection can be performed more easily than before, and inspection time can be shortened.

According to the embodiment as described above, it is determined whether or not a switching operation for performing a prescription different from that at the start of the infusion is performed, and in order to record the infusion history when the switching operation is performed, It is possible to record the history of infusions that were discontinued.
In addition, the switching operation is reliably performed to determine whether or not the switching operation has been performed by using the setting change operation of the flow rate, the scheduled amount and the integrated amount performed at the time of the prescription switching and the power-off operation before the completion of the infusion. Can be determined.
In addition, since the operation content of the switching operation is included in the progress log, it is possible to confirm by which switching operation the infusion was stopped.

In addition, the communication unit 33 can receive injection note information such as the identification ID of the injection note, the flow rate of the infusion, the scheduled amount of the infusion from the external terminal, and can transmit the injection note log and the progress log to the external terminal. It is possible to reduce the burden of input work on the patient chart by medical staff such as nurses. In addition, it is possible to prevent a mistake in transcription to the patient chart.
Furthermore, even if the medical staff cannot regularly check the infusion status, the progress log is periodically recorded, so that the progress log can be acquired collectively after the infusion is completed.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, the operation unit 31 may be configured by, for example, a keyboard, a mouse, a pointing device, a touch panel, and a voice input device.
The display unit 32 may be configured separately from the door unit 30.
The communication unit 33 may be connected to a network such as the Internet and configured to be able to communicate with an external terminal via the network.

When two or more injection note logs that are not transmitted to the external terminal at the time of communication are stored, the control unit 70 may warn that there is a possibility that a plurality of injection note logs are mixed. You may make it display on the display part 32 and may make the sound output part 50 output a warning sound.
When the injection log and the progress log are transmitted to the external terminal, the control unit 70 may delete them from the storage unit 60. At this time, the injection note log for which the end record has not been made may not be deleted from the storage unit 60.
When the injection note log and the progress log are transmitted to the external terminal, the control unit 70 may prohibit subsequent transmission without deleting them from the storage unit 60.

The infusion history recording unit 74 may record an injection note log and a progress log in a storage device such as a hard disk provided outside the medical pump 1.
The infusion history recording unit 74 may record the progress log at a preset time instead of after the predetermined time has elapsed.

In the above embodiment, the switching operation determination unit 77 determines that the switching operation has been performed when the setting of the flow rate or the predetermined amount is changed in a state where the infusion is stopped, but the infusion is not stopped. However, it may be determined that the switching operation has been performed if the setting of the flow rate or the predetermined amount is changed before the infusion is completed.
The switching operation determination unit 77 may determine that the switching operation has been performed when an identification ID of an injection note different from that at the start of the infusion is received from the external terminal.

The medical pump 1 may be configured such that various operations on the medical pump 1 can be input from an external terminal via the communication unit 33.
The medical pump 1 may include a printing unit, and print and output an injection note log and a progress log by the printing unit.
