Quest Medical RetroGuard® Arterial Check Valve

Use RetroGuard to prevent retrograde flow in the arterial line when using a centrifugal pump.

RetroGuard arterial check valve prvents retrograde flow in the arterial line when using a centrifugal pump. The one-way bicuspid valve stops retrograde flow to prevent the entrainment of air at the catheter site, suture holes and open vessels
The RetroGuard valve is intended to be placed proximal to the arterial filter within the filter bypass loop. This positioning allows for post-operative recovery of line blood and retrograde flow flow if repriming is necessary.
