Continuous catheter flushing flow control device

摘要

A flow regulating valve device providing continuous flushing of intravascular catheters with a flushing solution at either a restricted normal slow flow rate or intermittently at a catheter flush-out fast flow rate. The valve device has a cylindrical drum element rotatably mounted within a cylindrical chamber of a body member and provided with a diametrical flow-restricting capillary passage and a circumferentially extending, arcuate groove fast flow bypass passageway which are selectively moved into respective flow controlling positions by rotative adjustment of the drum element within the chamber. Biasing spring means on the device normally bias and maintain the body and stem members in their restricted flow rate relative rotative position while actuating arm means on these members enable manual rotative displacement thereof to their fast flow relative rotative position.
