Catheter flushing assembly
First Claim
1. An assembly for flushing primary flow lines associated with an intravascular catheter, said assembly comprising:
- a first flush port and a second flush port each connected in fluid communicating relation with a different one of said primary flow lines,a primary flow restrictor assembly disposed at a main junction of the intravascular catheter and said primary flow lines,said primary flow restrictor assembly structured to regulate fluid flow between said primary flow lines and the intravascular catheter,said primary flow restrictor assembly disposed in a closed position to define a flushing orientation of said first and second flush ports, andsaid flushing orientation further comprising each of said first and second flush ports connected in fluid communication with corresponding ones of said primary flow lines and a concurrent flow path of flushing fluid from said primary flow lines out through said first and second flush ports.

Abstract
An assembly for flushing at least the primary flow lines associated with a catheter, such as an intravascular catheter, comprising first and second flush ports connected in fluid communicating relation with a different one of said primary flow lines. A primary flow restrictor assembly includes two safety flow restrictors, disposed at a main hub of the catheter and the primary flow lines, and being structured to regulate fluid flow between the primary flow lines and the catheter. A flushing orientation is established when the two safety flow restrictors are concurrently disposed in a closed position, thereby establishing fluid flow between the primary flow lines and corresponding ones of the first and second flush ports, wherein one-way valves associated with each of the flush ports facilitate a concurrent path of flushing fluid from said primary flow lines and towards, out and through the first and second flush ports, to the external environment. Consequently, the flushing assembly of the present invention can prevent the introduction of flushing fluid, along with any bacteria or other collection of material carried by it, into a patient'"'"'s bloodstream.
