The PREVENT Advantage

PREVENT’s transparent wound interface (clear polymer) allows for direct wound visualization. It’s non-absorbent, non-porous polymer design resists fluid retention within the dressing, reducing conditions that typically support bacterial colonization and odor development seen with foam dressings. PREVENT’s non-compressible soft elastomer structure maintains consistent flow pathways, and does not collapse under negative pressure allowing for ease of intermittent/cyclic pressures. In fact, the PREVENT wound contact layer is optimized to function best when used at lower pressures (-50 to -80).

Don’t just take our word … the scientific data speaks for itself!

Dressing Placement

Traditional NPWT Dressings:

  • Trial and error in order to cut to wound size and shape takes excessive time
  • The foam pushes against the drape when trying to seal the wound
  • The foam retains fluid and makes a seal difficult

The Ease of PREVENT

  • The PREVENT can be cut right over top
  • The wound can be visualize through the PREVENT
  • The PREVENT sits inside the wound with no expansion against the drape or the wound edges
  • There is minimal to no fluid retention with the PREVENT

Fluid Retention

Benchtop test showed that PREVENT allowed 45% more exudate to be removed as compared to foam.

  • 3.5 hour test at -125mmHg
  • Instillation was set at 200mL/hr
  • Total of 360mL instilled through both dressings
  • 360mL infused into foam & PREVENT
  • 229mL out foam (131mL retained)
  • 331mL out PREVENT (29mL retained)

Clinical observations relating to traditional ROCF’s fluid retention issues.

  • Foam is perfect medium to hold fluid on the wound
  • Perfect medium for bacterial overgrowth
  • Wound colonization negatively affects healing
  • Staph & Pseudomonas colonization
  • Foam is poor for fluid transmission/irrigation
  • Instillation through a dirty sponge
  • Foam is opaque and cannot see the wound through it
  • Foam compresses & expands to degrade the seal

Unmatched Efficiency

  • PREVENT does not hold fluid
  • Significantly reduced resistance to flow
  • We expect reduced bacterial load
  • We expect improved healing
  • Studies to be done but very intuitive
  • PREVENT is clear so you can see the wound
  • PREVENT is non compressible but also very soft and pliable
  • PREVENT will mold to any contour of the wound.
  • No pressure up against seal

PREVENT allows for easy use of intermittent suction

Intermittent suction allows for tissue re-perfusion and improved blood flow.

0 to -55 mmHg

-55 to -20 mmHg

-20 to -55 mmHg

The foam collapses on itself pulling against the seal.

The foam pushes against the seal and may pull in-grown tissue causing pain when suction is reduced.

Wound Contraction

The PREVENT performs similar to the foam dressing and allows for contracture at lower pressures.

0 to -125 mmHg (6mm)

0 to -50mmHg (7mm)

Patient came to us with mostly clean wound beds but colonized with gram negative bacteria… (Observation with initiation of NPWT with PREVENT) there was extensive skin formation. He lost on the right leg 7 cm of length and 30 cm of width… Yes, it is completely skin 48 hours after the Clear Choice came off. If you had asked me this morning, if that was even possible, I would have told you “no”. He’s thrilled! — Wound Nurse, Columbia, MO
