A connector connects a silicone or other radially expandable catheter to a catheter that does not expand radially. The catheter includes a hollow first connection part, a hollow second connecting part and a locking sleeve. The hollow second connecting part is threadably connected to the first connection part. The second part has a rib protruding from an external surface thereof. The rib has a recessed notch. A locking sleeve has a lip projecting radially inwardly therefrom at each end. The lip at the second end is fixedly received within the recessed notch. The lip at the first end is disposed about the external surface of the first connection part. The locking sleeve is axially movable with respect to the first connection part. Axial movement of the locking sleeve in one direction is limited, thereby preventing disassembly of the first connecting part and the second connecting part.
FIG. 2 is a cross-sectional view of the connector of FIG. 1, shown being fluidly connected to a kink proof catheter;
FIG. 3 is cross-sectional view of the kink proof catheter; and
The hollow second connecting part 14 is threadably connected to the first connection part 12. The second connecting part 14 has a first end 52 and a second end 54. First end 52 has an external threaded surface 56 that mates with the internal threaded surface 34 of the first connection part 12. The second part 14 has a rib 56 protruding from an external surface thereof. Rib 56 has a recessed notch 58.
In use, the kink proof catheter 26 is placed within the second connection part 14 until its distal end abuts the third shoulder 48 of the first connection part 12. To hold and seal catheter 26 within the connector assembly 10, the user can then simply rotate second connecting part 14 with respect to first connecting part, thereby moving these parts from the position illustrated in FIG. 1 to the position illustrated in FIG. 2. During this movement the collet 18 is moved (to the left as illustrated in the drawing Figures) such that the collet's beveled surface 68 slides against beveled shoulder 70, thereby causing the distal end of the collet 18 to compress about catheter 26, thereby holding catheter in place. Collet 18 is compressed by forces that are below its yield strength. Thus, upon removal of the external force (e.g., unscrewing second connection part 14 from first connection part 12), the collet will return to its original position, and will no longer hold catheter 26. Therefore, the connector can be reused many times to hold and seal about a kink proof catheter. Simultaneously, this advancement of second part 14 into first part 12 causes o-rings 22 to compress between the spacer 20 and the second part 14, thereby forming an effective seal about catheter 26 and the internal surface of the second connecting part 12.
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 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;
