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
