Approximately 80 cubic centimetres (roughly 6cmx6cmx2cm) You can cut the foam and stack it on top of each other, but this is the maximum depth.

You can use any interface such as gauze for packing and the white foam as long as the overall dressing capacity (as per above) is not breached

15cm x 7.5cm

Yes you can, as you would with other NPWT devices that you have used previously.

Yes, charge the device for approximately 2 hours before first use.

Yes, the device needs to be in the carry case at all times, except when changing the fluid container. Carry cases can be purchased separately for additional patients.

The pressure is set at the dressing and can be ordered as either a -125mmHg dressing or -75mmHg dressing.

The green light is on when the pump is working correctly.

Check the battery is charged. Check that the grey strap is secure and there are no red lights.

Please seek guidance from your clinician if you can not get the device working.

If the device is unable to pull down the dressing or the dressing is not compressed, check the dressing is firmly sealed around the wound. Use additional film drape if necessary, around the drape edges. Check dressing connector is properly locked. Check the Fluid Container Pack is fully engaged into the device.

If there is no fluid mobility in the tubing and the dressing is not compressed, there may be a blockage. This will cause the device to make an uncharacteristic slapping noise.

To resolve a blockage, check that there is no kinking in the tubing, or the tube is occluded. If there is, either straighten the kink or replace the dressing and/or Fluid Container Pack.

Clean and disinfect the device between patients by wiping down with damp cloth using disinfectant and water or non-aggressive cleaning material such as isopropyl alcohol.

No, it doesn’t.

When the red light is lit, the device will stop running.
If the red light is lit there are two possible reasons:

1. The Fluid Container is full and requires changing.
2. The strap has not been correctly attached to the device.

Ensure the Strap is engaged over the fastener on the front of the device.

• If the Fluid Container is full of air, ensure the device is operated in its upright position.
  • When a new Fluid Container Pack has been installed and the strap engaged, the red light will go out and the device will restart.
  • The device will restart at maximum speed for 3 minutes. If required, open and close strap to give an additional 3 minutes of high speed.

The device has a feature to see how many days remain on the device.

With the device turned off, open the grey cover. Press and hold the grey button, then press and hold the power button for 8 seconds. The RED light will flash to indicate the 10s and the ORANGE light will flash to indicate the 1s.

For example: 4 Red flashes and 2 Orange flashes will indicate 42 days remaining. 2 Red flashes and 8 Orange flashes will indicate 28 days remaining.

To resume therapy, press the power button.

The device has a lifetime of 1344 hours continuous use.

The device will alert the user when 3 days are remaining. At the beginning of the 3-day warning period, all LED’s will flash for a short period of time. Every hour all LED’s will flash for a short period of time.

At 1344 hours, all LED’s will flash for a short period of time and the device will shut down. If the device is switched on following shut down, all LED’s will stay illuminated but the device will not function.

Return in the pre-paid packaging back to the manufacturer, who will recycle the parts.

The Temperature Range is:

NEXA Device and Fluid Container Pack: -25°C (-13°F) to +70°C (158°F)

NEXA Dressing: 10°C (50°F) to +27°C (80°F)

Will I know if there is a leak?

• the Nexa device doesn’t have a leak alarm. Due to the unique action of the device, it will continue to remove wound fluid irrespective of vacuum levels.

How will I know if there is a blockage?

• a blockage will cause the machine to make an uncharacteristic slapping noise. Check there is no kinking in the tubing or that the tube is occluded. If there is either straighten the kink or replace the dressing/fluid container.

How do I know the fluid container is full?

• the red light will come on. Change the fluid container.

Can I shower with the pump and dressing in place?

Can I remove the dressing?

• No, this should be done by your nurse or doctor.

How will I know if the device needs charging?

• The battery is LOW when the orange light is ON. Plug the Nexa into the mains, the orange light flashes while the battery is charging.

Why has the pump stopped working?

• The battery needs to be charged or the pump has stopped working after fifty-six days of use.

Can I switch the device off to take a shower and if so for how long?

• there is no maximum permissible time limit for the machine to be switched off for activities such as showering.
• The manufacturer recommends  the least amount of time possible to be disconnected from the device as this will have a clinical impact on the therapy provision and should be considered on a case by case basis by the clinician.

• If it changes from clear to cloudy or bright red or you see the dressing fills rapidly with blood
• Your wound looks more red than usual or has a foul smell
• The skin around your wound looks reddened or irritated
• The dressing feels or appears loose
• You experience pain
