Priming Volume: 6 mL
Opening Pressure: ≤ .5 psi
Flow Rate: Between 35 to 3500 mL

Automatically prevents retrograde arterial blood flow



  • Reduce the amount of connections made during a case.
  • Reduce tubing being added to an already complicated IV configuration.

Peace of mind

  • A Perfusionist can “connect it and forget it”.
  • An extra safety guard that protects your patient from dangerous outcomes due to error.


  • The manufacturer of the new oxygenators encourages the 3/8 retro-guard as a second line of defense.
