Safe & Confident Under Pressure
When it comes to important perfusion equipment inside the perfusion circuit, Quest Medical safety valves can perform a critical role for perfusion safety. Quest safety valves offer optimum prevention of retrograde flow, negative pressure, and related hazards.
With safety and quality as a top priority, Quest develops and manufactures all Safety Valves in the USA. Each type of valve is available as sterile and/or non-sterile direct from Quest Medical, Inc. and from procedure kit suppliers.
RetroGuard®
Confident One-way Flow Control
The Quest RetroGuard automatically prevents retrograde flow in the arterial line when a centrifugal pump is used. Large duckbill valve minimizes resistance to flow
Materials:
- Silicone duckbill valve
- Acrylonitrile Butadiene Styrene (ABS) housing
- Not made with latex
Available sterile (REF 4007100) and non-sterile (REF 4007200) from Quest Medical, Inc. and all procedure kit suppliers.
Safe Vacuum Relief
