Abstract:
1. A connector assembly comprising: a hollow first connection part having a first end and a second end, said first end having a barb protruding from an external surface thereof for connecting to a silicon tube, said second end having an internal threaded surface, and an externally projecting annular rib, said internal surface extending from said second end to said first end with said internal threaded surface, a first bore, a first shoulder transitioning to a second reduced diameter bore, a second shoulder transitioning to a third further reduced diameter bore, said second shoulder having at least a portion thereof being beveled; a hollow second connecting part being threadably connected to said first connection part, said second connecting part having a first end and a second end, said first end having an external threaded surface that mates with the internal threaded surface of said first connection part, said second part having a rib protruding from an external surface thereof, said rib having a recessed notch; a locking sleeve having a first end and a second end, each of said ends having a lip projecting radially inwardly therefrom, said lip at said second end being fixedly received within said recessed notch, said lip at said first end being disposed about said external surface of said first connection part on a side of said externally projecting annular rib of said first connection part remote from said second end of said first connection part, said locking sleeve being axially movable with respect to said first connection part, said axial movement in one direction being limited by abutment of said externally projecting annular rib of said first connection part and said inwardly projecting lip on said first end of said locking sleeve, thereby preventing disassembly of said first connecting part and said second connecting part; a kink proof catheter being disposed within at least a portion of said first connection part and said second connection part, said kink proof catheter being essentially inflexible to radial expansion thereof; a collet being disposed about at least a portion of said kink proof catheter and within said second bore of said first connection part; at least one o-ring being disposed about at least a portion of said kink proof catheter and within said first bore of said first connection part; a spacer being disposed about at least a portion of said kink proof catheter and within said first bore of said first connection part; and a silicone catheter being disposed about said first end external surface of said first connection part.
