IV Set Installation
（1）Under normal conditions, insert an ordinary PVC
IV set into the outlet of infusion bottle/bag.
（2）Slightly squeeze Murphy’s dropper with fingers, to
make its 1/3 volume fill with liquid (see figure 9)
Notes：To ensure normal drip, never fill the dropper with water,
otherwise the infusion pump cannot detect drip drops and will cause
alarm; if the volume is less than 1/4, the bubble will easily go into
the infusion tube and cause bubble alarm.
Notes: Please make sure that the air filter and inlet tube of infusion bottle/bag are smooth, otherwise it may
cause vacuum inside, then up occlusion happens, and prompt alarm.
Purge the air inside the infusion tube, make sure
no bubble inside, then close the adjustable clamp
of ordinary PVC set to prevent loss of liquid.
Open the infusion pump door, turn the locking
clamp (F) to the left to put the infusion tube.
Put the infusion set into guide slot A between
the liquid bottle/bag and the device.
Put the infusion tube into the guide slots B,C,D,E,
F, G and H vertically, so that the infusion tube can
be a straight line, as shown in figure 10.
Close the pump door tightly, then open the
infusion set adjustable clamp.
Notes：1. Make sure the infusion tube is put into the
bottom of ultrasonic sensor (guide slot C),
otherwise bubble alarm would happen.
2. Make sure no liquid drips in the Murphy’s dropper this moment (i.e. no leakage).

Operation Flowchart
Infusion operational processes
Power On
Connect the power wire, then the light indicator lights up, the AC power is connected, long
press the power button for 3 seconds to start up.
Machine launches self-check after starting up, the contents of self-check include: whether the
batteries is normal, whether the system is normal, whether the pressure sensor is normal, etc., after
self-check completed, machine would enter infusion standby interface, waiting for user to input
infusion parameters.
Notes：Not connect the AC power supply or the AC power is interrupted, machine would switch to battery
power supply automatically, infusion pump would prompt AC falls off; working on the condition of
battery power supply, pay attention to the risks of battery power off, so please connect the AC power
supply as soon as possible.

Volume mode operation
Infusion mode selection
Press in stop, display infusion mode interface. If the present mode is volume mode, so not need to
select mode.
Choose “volume mode” with up or down key.
Press , then return to infusion interface after volume mode is chosen.
VTBI/Rate/Time
Move the cursor to corresponding input boxes of rate, VTBI and time with the up or down key.
Set rate.
Set VTBI
Set time. (if need)
Press
Notes: set every two of these three parameters, the rest one will be calculated automatically, the machine would
calculate another parameter with the two last input parameters. And infusion would begin according to the
two last input parameters.

- 17 -

key (0-9), “OFF” would disappear, exit the simple infusion mode.
2. Drop sensor plays a role in monitoring during simple infusion mode, it would prompt the alarm of
empty when detecting no liquid drips.

- 18 -
Program mode
Custom can himself define 8 stages of program mode to infuse automatically. Allow to suspend
programming in process of infusion, but KVO would be launched during programming pause. If the rate of
previous program is less than 1ml/h, then the KVO begins according to the rate of previous program; if the
rate of previous program is greater than 1ml/h, then the KVO begins according to the rate of 1ml/h.
Infusion mode selection
Press in starting up status, display infusion mode interface.
Choose “program mode” with up or down keys.
Press to enter program mode interface.
VTBI/Rate Setting
Programming interface Preview interface Infusion interface
