The document provides instructions for use of a closed cyclic negative pressure wound therapy (CCNPWT) system. It describes how the system works to promote wound healing through application of controlled negative pressure. It outlines the device components, settings that can be adjusted, and steps for dressing installation and troubleshooting potential issues. Accessories including wound drainage kits, consumables and their specifications are also listed.

Reduces oedema
Enhances dermal perfusion

Stimulates cell proliferation
Promotes granulation tissue formation.
Studies suggest mechanical stretching

Pressure Therapy decreases wound
volume approximating wound edges,
helps uniformly draw wounds closed
Promotes
continuous
wound
debridement by removing wound micro
debris & bacteria colonized wound
output / interstitial fluid allowing tissue
decompression
Protects wound from re-infection, cross
infection or spreading further infection
Promotes Skin Graft/Flap uptake (The
sterile flexible foam dressing gently
presses the skin graft or flap ensuring full
contact with the wound bed &
simultaneously removes wound output
ensuring moist healing environment)

Switch on the CCNPWT System, You will see
the home screen showing
SELF TEST MESSAGE (SEE: snap shot
image 1).
After self test system will try achieving the
target pressure set already or during previous
therapy session. Pump will stop once the
actual pressure equals target pressure, when
it will fall again pump will restart, process will
continue like this (SEE: snap shot image 2).
To Change pressure settings click the menu
button, select the setting as in (SEE: snap shot
image 3) by pressing UP / DOWN switch, the

PRESSURE NOT ACHIEVING TO TARGET PRESSURE
Unplug the filter tube and clamp & see Actual Pressure =
Target Pressure
if OK
If NOT Check the VACUUM PORT Connector or it could be a
machine problem
Proceed to Next Step
Unplug the other end of the filter and clamp & see if Actual
Pressure = Target Pressure
if OK
If NOT, possibly filter is malfunctioning
Proceed to Next Step
Clamp the Canister tube & see Actual Pressure = Target
Pressure
if OK
If NOT, possibly canister is leaking or faulty.
Proceed to Next Step
Connect the dressing tube with the canister tube & Clamp the
dressing tube & see Actual Pressure = Target Pressure
if OK
If NOT, possibly the canister & dressing tube joint is leaking
or not properly connected.
then CHECK DRESSING SEAL

Check the MAINS Cable / POWER
Cable is connected to the power
socket & is switched ON.

CCNPWT System is RED GLOWING
See the BATTERY SWITCH in the
CCNPWT System is ON (PRESSED I)
(ON POWER)GREEN LED
(ON BATTERY) RED LED
IF ONLY RED is ON, that
shows/indicates the system is working

IF ONLY GREEN is ON, that shows/indicates the system is on MAIN supply
IF BOTH RED & GREEN is ON, that shows/indicates the system is working
on MAINS supply & battery is charging. In absence of MAIN supply power
sytem will automatically switch over to battery standby. (IDEAL CONDITION)
ENSURE the RED & GREEN LED/LIGHT in the front panel or in the left side of

Ensure the canister gets replaced between 450ml -500ml
accumulation of fluid
or this may choke the filters or even can damage the system
pump (if continued further or for longer period).
IF canister is not full remove the filter tube & run the system.
IF OK, then connect the filter & CHECK for any blockage in
the filter.
IF OK connect the canister without connecting the dressing
tube to CHECK any tube blockage or tube folds/kink.
IF OK, there could be drainage tube blockage or mismatch
hole with the dressing/drape sealed.
Check with a needle prick in the dressing (Close to Drainage
Tube junction point).
