WARNING:
The ambIT
®
pump requires the use of an ambIT
®
cassette. Use of cassettes
not manufactured by Summit Medical Products, Inc. may cause the pump to
malfunction and may cause an over-infusion or an under-infusion.
NOTE:
If an ambIT
®
cassette already has a filter, it is not recommended to use a separate
air elimination filter. Using a second filter may cause the pressure to exceed the
activation pressure for the pressure switch, causing an occlusion alarm (“OCL”
in display and a constant beep delayed for 3 minutes).
2.2
ambIT® Cassette
The cassette contains a rotary mechanism that pumps the infusion
solution at an accurate and controlled rate.
During cassette priming, fluid will flow freely through the tubing
(see upper figure to the left
).
After priming, snap the cassette bottom disc into the body of the
cassette to close the fluid path. This prevents, the free flow of fluid
(see lower figure to the left). When primed, the cassette simply
snaps onto the pump.
WARNING:
Free flow will occur until the cassette bottom disc is snapped in place. No
alarm will sound if the cassette bottom disc is not snapped in place. Do not
attach the cassette to the patient until the cassette is placed on the pump or the
cassette bottom disc is snapped into place. Placing the cassette on the pump will
automatically snap the disc in place and prevent free flow.
NOTE:
Once the cassette bottom is snapped into place, the rollers engage and compress
the tubing, preventing fluid from flowing unless the pump is rotating and
moving the fluid. If a downstream occlusion occurs, the pump will alarm and
notify the user.
2.3
Priming the Cassette
WARNING:
Do not use a cassette if the outer package is torn, punctured, wet or damaged.
Do not touch sterile open ends of the tubing. Use the aseptic technique utilized
by your facility.
WARNING:
The cassette must be primed before use by removing all air from the solution
container and tubing.
