When the AC cable is connected to the power connector 1 and connected to an outlet, the indicator lamp 5 during charging is turned on. When the power switch 2 is pressed here, the normal power lamp 3 is turned on.
Subsequently, the monitoring device 305 operates to check each function. When the function check is completed, the buzzer sounds and the injection amount setting display is displayed as 0.0 (reference numeral 18 in FIG. 1).
When the syringe model is not designated, the indicator lamps 19 to 22 blink to indicate that the syringe model is not designated. When designated (reference numeral 403 in FIG. 4), one of the display lamps is turned on. Here, the once specified state can be stored in the control device 301 so that it is recognized as the previous state unless it is canceled from the next time. Next, when the syringe to be used is set by operating the clamp 103, the volume of the syringe is detected (reference numeral 404 in FIG. 4), and one of the syringe displays 23 to 25 lights up. When the input switch 29 is pressed, continuous liquid transfer → repeated liquid transfer → intermittent liquid transfer → program → continuous liquid transfer →
The display lamps are switched in this order, and the usage mode can be set (reference numeral 405 in FIG. 4). Note that this setting can be performed immediately after the program starts.
In that case, for example, after a lapse of a certain time (about 2 minutes) after the power is input, it is possible to warn that the buzzer is not performing the setting operation. The control device 301 determines which operation should be performed by this setting operation (reference numerals 406, 412, 422, 433 in FIG. 4).

Continuous Liquid Delivery Mode This is the step indicated by reference numerals 407 to 411 in FIG. Press the number keys 17 to set the liquid delivery amount.
The injection pattern in the continuous liquid transfer mode is as shown in FIG. When the start switch 6 is pressed, injection is performed. When the capacity is 5% or less, the remaining amount alarm is issued. When the capacity is exhausted, the operation ends (reference numeral 445).

Repeated Liquid Delivery Mode This is the step indicated by reference numerals 413 to 421 in FIG. Press the number keys 17 to set the one-shot liquid transfer amount. Press the number keys 17 to set the sustained flow rate (flow rate to be sustained after one shot). Then
Specifies the duration of the sustain cycle. The injection pattern in the repetitive liquid transfer mode is as shown in FIG. When the start switch 6 is pressed, injection is performed. When the capacity is 5% or less, the remaining amount alarm is issued. When the capacity is exhausted, the operation ends (reference numeral 445).

Intermittent Liquid Delivery Mode This is the step indicated by reference numerals 434 to 441 in FIG. Press the number keys 17 to set the one-shot liquid transfer amount. Press the number keys 17 to set the sustained flow rate (flow rate to be sustained after one shot). Then
Specifies the duration of the sustain cycle. When the time of this sustain cycle is set again, the time of the next second shot is set. This is repeated sequentially. That is, 429,430
The steps of are repeated. The injection pattern in the intermittent liquid transfer mode is as shown in FIG. When the start switch 6 is pressed, injection is performed. When the program amount is finished, the operation is finished (symbol 445).

Program Liquid Delivery Mode This is the step indicated by the reference numerals 423 to 432 in FIG. Press the number keys 17 to set the one-shot liquid transfer amount. Press the number keys 17 to set the sustained flow rate (flow rate to be sustained after one shot). Then
Press the number keys 17 to set the one-shot liquid transfer amount.
Press the number keys 17 to set the sustained flow rate (flow rate to be sustained after one shot). This is repeated sequentially. That is, steps 434 to 437 are repeated. The injection pattern in the programmed liquid delivery mode is as shown in FIG. When the start switch 6 is pressed, injection is performed. The operation ends when the program amount is completed (code 4
45).
