How to Apply NPWT (continued)
4. Attach Wound Care Set to the VENTURI
®
AVANTI
/
VENTURI
®
COMPACT power unit
canister by lining up locator stud on the tubing connector with the notch on the
canister tubing port located on top corner of canister, pushing down gently and twisting
clockwise to lock. A tube guide is tted to assist with the routing of the tubing.
5. OPERATING THE VACUUM POWER UNIT:
a) If using the mains or vehicle power adapter, insert the smaller end (DC outlet) of
the supplied power adapter cable into the side of the VENTURI
®
AVANTI / VENTURI
®
COMPACT power unit, and the other end into the appropriate power outlet. The
power adapter indicator should be illuminated.
NB. The battery will charge when the unit is connected to the power source
(indicated by battery charge status icon on display screen scrolling from left to right)
and provides automatic power back-up if the external power supply or adapter fails.
It is recommended to use the power adapter when convenient to do so as this will
ensure the battery is fully charged when needed. A fully discharged battery will take
a number of hours to fully charge.
b) Press RUN/STOP button to invoke and display STAND-BY mode (the power unit
will beep and therapy mode, operating pressure and battery charge status will be
displayed).
c) The power unit will default to continuous therapy mode at 80mmHg. To switch
between continuous and intermittent therapy modes, press and hold the THERAPY
MODE button until power unit beeps to confirm change of mode. Adjust vacuum
level if required using the UP and DOWN arrow buttons.
d) Press RUN/STOP button again to initialise and run the power unit.
NB. Vacuum level and therapy mode can be adjusted when in stand-by mode and
for up to 1 minute after power unit is running. Power unit will automatically lock 1
minute after last button operation when running to prevent inadvertent operation
of button functions (except MUTE), as indicated by 'L' on the display screen. Press
and hold the UNLOCK button until power unit beeps if further button operation is
needed. Display screen is only illuminated for a short period after button operation
in battery mode.
6. Once the power unit is running, observe the wound site. The dressing should contract
noticeably, becoming rm to the touch. If the dressing fails to contract, the dressing
has not been completely sealed. Reinforce the dressing seal and/or adjust the drain
and initiate suction again.
WARNING: Particularly when used outside of a medical institution, get immediate
medical assistance from those responsible for the prescription and setting of
the NPWT system should any of the following occur:- obvious bleeding or pain;
the wound site or exudate presents unexpected changes in its condition, colour or odour;
the wound dressing becomes detached or ineffective; the tubing becomes blocked.
7. To change or remove dressing, unlock power unit (press and hold UNLOCK
until power unit beeps), then press and hold the RUN/STOP button until
power unit beeps three times to return to stand-by mode. Clamp Wound
Care Set tubing and remove by turning anticlockwise and lifting out of tubing
port on canister. Dispose of used Wound Care Set according to local clinical
waste policy. If required, apply new Wound Care Set and continue NPWT.
