5) How to use Flush
Hold both sides of the flush operator and pull upward gently. Do not revolve the operator and
take care not to put the power on one side.
Caution
If a fast flush is performed on the patient, the user should check
carefully for the presence of foam and particulate matter. If a large
volume is flushed by force, a short flush with an increase rate less
than 2cc is recommended to avoid central embolism.
Blood pressure for a liquid infusion line over 300mmHg requires an
infusion of more than 3cc per hour. In this case, the pressure must
not exceed 775mmHg. A protective function is set in the flush
device, which prevents overpressure of the converter by making the
liquid bypass the device. If a more precise control of fluid volume is
required, it is necessary to connect the infusion pump around the
flush device.
6-1) Twist the sterilized solution bag lightly using a drip chamber spike
6-2) Open the roller clamp and remove the air inside the bag completely by squeezing
using an infusion set or a needle inserted into the injection port in the back. By emptying
the back this way, it can prevent air input into the patient’s body.
6-3) Before inputting the solution into the infusion set, push both sides and fill the drip
chamber partially.
6-4) Operate the flush device gently. Since air rises from the bottom, make sure that the
solution is in the bottom at all times.
6-5) Prime the side ports and the plug of the zero point stopcock in the converter using a
door-lock plug.
6-6) Check if bubbles are present in the monitoring system. To check the presence of
invisible bubbles, rap it lightly
6-7) Add pressure to the system up to 300mmHg using C-fuse or the clear cuff. Flush the
system for 2~3 seconds. Check for the presence of air bubbles which may result from a fast
flush. Now, the system is ready for zero point setting and measuring. Place the stopcock in
a 90 degree position to let it off state.
