The Better-Venter ™ The Better-Venter is designed for use in an extracorporeal circuit to prevent excessive negative pressure during venting. It is a complete circuit for the roller pump that provides safer venting in two ways: the pump tubing collapses, and a shunt between the inlet and outlet pump tubing breaks suction, such that maximum suction generated is nominally -300 mmHg. The Better-Venter also incorporates a one-way valve in the inlet tubing to reduce the possibility of flow returning to the heart. Get the the latest Brochure |
