What type of wounds can you use Nexa on?
  • Chronic wounds
  • Pressure ulcers
  • Diabetic foot ulcers
  • Venous leg ulcers
  • Surgical wounds
Are there any contraindications?

As with all topical negative pressure, Nexa is not recommended for treatment of the following conditions:

  • Presence of necrotic tissue
  • Malignancy in wound
  • Untreated Osteomyelitis
  • Untreated malnutrition
  • Exposed arteries, veins, nerves, or organs
  • Use over anastomotic sites
  • Non-enteric and unexplored fistulas
  • Necrotic tissue with eschar
What size wound can you use Nexa on?

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

Can you bridge with the dressing?

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

Does the device need charging before use?

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

Do you need to use the carry care?

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.

How do I set the pressure?

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

How do I know if the therapy is working correctly?

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

The device won’t start. What do I do?

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.

What do I do if there is a leak?

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.

What do I do if there is a blockage?

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.

How to I clean the device between patients?

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.

The battery low indicator light is on, what should I do?

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.
How do I know how many days are remaining on the device?

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.

Does the device alert you when it is nearing the end of its life?

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.

How do I dispose of the device at the end of its life?

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

Does it need to be stored at a certain temperature?

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)

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.

  • 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
