Catheter connector insert
View Patent ↗The present invention relates to a catheter connector configured to provide an escape location for a liquid medium trapped therein. The catheter connector includes a body having a proximal end and a distal end. The proximal end includes a proximal end port for mating communication with a fluid delivery device. The body defines a hollow interior extending from the proximal end to the distal end. In one embodiment, the catheter connector includes an insert configured within the hollow interior of the connector. The insert defines a bore therethrough that is configured to receive a catheter at least partially therein. Further, the bore includes an interior wall and an exterior wall defining a thickness therebetween. The interior wall includes at least one discontinuity. Thus, when the catheter is inserted through the bore, at least one cavity is formed by the catheter and the at least one discontinuity of the insert. The cavity is configured to collect a liquid medium within the catheter connector, thereby maintaining a secure connection between the catheter and the catheter connector. In another embodiment, the hollow interior of the catheter connector may be manufactured with at least one discontinuity so as to form a cavity configured to collect a liquid medium within the catheter connector.

3. The catheter connector of claim 1 , wherein said plurality of discontinuities extend from said bore through a portion of the thickness of said insert.
4. The catheter connector of claim 1 , wherein said plurality of discontinuities are spaced circumferentially about said interior wall.
5. The catheter connector of claim 4 , wherein said plurality of discontinuities are spaced equally about said interior wall.
6. The catheter connector of claim 4 , wherein said plurality of discontinuities are spaced randomly about said interior wall.
7. The catheter connector of claim 1 , wherein said plurality of discontinuities comprise at least one of a rib, a ridge, a protrusion, a peak, a valley, a channel, a through hole, an aperture, or a void.
8. The catheter connector of claim 1 , wherein said plurality of discontinuities comprises a plurality of peaks spaced circumferentially about said interior wall, said plurality of peaks spaced apart by a plurality of valleys.
9. The catheter connector of claim 8 , wherein each of said plurality of peaks and each of said plurality of valleys comprise at least one non-arcuate edge.
10. The catheter connector of claim 8 , wherein each of said plurality of closed cavities comprise a triangular cross-section.
11. The catheter connector of claim 8 , wherein each of said plurality of peaks and each of said plurality of valleys comprise at least one arcuate edge.
12. The catheter connector of claim 1 , wherein said insert comprises a flexible material, wherein said flexible material comprises at least one of or a combination of the following: a rubber material, a polymeric material, a silicone material, or an elastomeric material.
13. A catheter connector, comprising:
a body having a proximal end and a distal end, said body defining a hollow interior extending from said proximal end to said distal end;
a proximal end port configured with said proximal end of body for mating communication with a fluid delivery device,
wherein said hollow interior defines a bore therethrough, said bore configured to receive a catheter at least partially therethrough, said bore comprising an interior wall comprising a plurality of discontinuities,
wherein, when the catheter is inserted through said bore, a plurality of individual closed cavities are formed by the catheter and each of the plurality of discontinuities of the insert, each of said individual closed cavities configured to collect and trap a liquid medium therein.
14. An insert for a catheter connector, comprising:
a body configured to fit within a hollow interior of the catheter connector,
said body having a proximal end and a distal end, said body comprising a bore extending from said proximal end to said distal end, said bore configured to receive a catheter at least partially therethrough, said bore comprising an interior wall comprising a plurality of discontinuities,
wherein, when the catheter is inserted through said bore, a plurality of individual closed cavities are formed by the catheter and each of the plurality of discontinuities, each of said individual closed cavities configured to collect and trap a liquid medium that may enter the catheter connector, thereby maintaining a secure connection between the catheter and the catheter connector.
15. The insert of claim 14 , wherein said plurality of discontinuities are spaced circumferentially about said interior wall.
16. The insert of claim 15 , wherein said insert comprises a flexible material, said flexible material comprising at least one of or a combination of the following: a rubber material, a polymeric material, a silicone material, or an elastomerie material.
17. The insert of claim 14 , wherein said plurality of discontinuities comprise at least one of a rib, a ridge, a protrusion, a peak, a valley, a channel, a through hole, an aperture, or a void.
