Cardiopulmonary bypass system valve, unidirectional flow/pressure control

These are sterile, single-use mechanical regulators designed for use in cardiopulmonary bypass systems during open-heart surgery. They are typically integrated with centrifugal pump setups to manage blood flow and pressure, ensuring unidirectional movement to prevent backflow of blood or air into the heart. They also help maintain controlled suction levels to keep lines patent during procedures like left ventricular venting or to clear the surgical field.

Devices in this category are supplied as single-use, sterile components intended for one surgical procedure. They are designed to interface with bypass circuits to provide precise flow and pressure control, acting as safety and functionality safeguards. Their design focuses on preventing retrograde flow and managing vacuum levels to protect both the patient and the integrity of the extracorporeal circuit.
