Abstract
An apparatus for providing continuous flushing of intravascular catheters. The apparatus consists of a small block having passages which define a continuously open path through which flushing solution is introduced into a catheter. A flow resistor is placed in the continuously open path in order to limit the flushing solution to a desired small amount. At least a portion of the block consists of a resilient sleeve which surrounds the flow resistor. The resilient sleeve provides a by-pass passage around the flow resistor. A disk placed in the by-pass passage cooperates with the resilient sleeve selectively opened to permit relatively large amounts of flushing solution to be introduced into the catheter when desired.
