SensaT.R.A.C. Technology

An Essential Component of V.A.C. Therapy

ActiVAC with SensaTRAC
The only NPWT system that monitors pressure at the wound site and adjusts accordingly, patented SensaT.R.A.C.™ Technology ensures the prescribed negative pressure is maintained for optimal healing outcomes.




Why SensaT.R.A.C. Technology?

  • Movement of wound fluid against gravity, as well as viscosity of the exudate in the tubing, influences negative pressure delivery
  • Only SensaT.R.A.C. compensates for pressure variances at the wound site due to patient position, movement and exudate characteristics

  Bar Chart  

An in-vitro study* showed that when a simulated wound model was lowered 36 inches (91 cm) below the vacuum pump, the pressure drop was significantly less (p=<.005) using V.A.C.® Therapy with SensaT.R.A.C. and GranuFoam™ Dressing than NPWT with gauze or NPWT with reticulated open cell foam without the benefit of regulated pressure feedback and control from SensaT.R.A.C.™ Technology.

What is SensaT.R.A.C. Technology?


SensaTRAC Pad

SensaT.R.A.C. Pad

  • Distributes negative pressure to individual sensing lumens
  • Helps reduce tubing blocks and false alarms though enhanced fluid dynamics
  • Enhances patient comfort with a low profile design

SensaTRAC Tubing


SensaT.R.A.C. Tubing

  • Efficiently draws exudate away from the wound larger lumen
  • Independently monitors target pressure at the wound through the outer sensing lumens
  • Allows for secure and convenient tubing connections


Monitoring Software

  • Continuously regulates negative pressure feedback
  • Maintains prescribed negative pressure at the wound site by adjusting pump output
  • Safety alarms alert caregivers if target pressure is not met or therapy is interrupted
