1. A detachable hub for a catheter comprising:a first portion having a first distal end, a first proximal end, and a longitudinal channel extending therethrough between the first distal end and the first proximal end; wherein the first proximal end includes a pivoting locking member; and a second portion having a second distal end, a second proximal end, wherein the second distal end includes a locking receiver, and wherein the longitudinal channel is sized to allow the first proximal end to be disposed over the second distal end such that the pivoting locking member is engageable with the locking receiver. 2. The detachable hub according to claim 1, wherein the pivoting locking member comprises a cam and wherein the locking receiver comprises a saddle, such that, when the first proximal end is disposed over the second portion of the hub, the cain engages the saddle when the pivoting locking member is pivoted into a locking position.3. The detachable hub according to claim 1, wherein the second portion further comprises a plurality of channels extending generally longitudinally therethrough.4. The detachable hub according to claim 1, wherein the second distal end is constructed from a first material and the second proximal end is constructed from a second material.5. The detachable hub according to claim 4, wherein the second distal end comprises a saddle, such that, when the first proximal ends disposed over the saddle, the pivoting locking member is aligned to engage the saddle.6. The detachable hub according to claim 1, wherein the pivoting locking member further comprises a recess and the second proximal end comprises a projection extending therefrom, such that, when the pivoting locking member is engaged with the locking receiver, the projection is disposed within the recess.7. The detachable hub according to claim 1, wherein the second portion further comprises a plurality of hub cannulae extending therethrougb.8. The detachable hub according to claim 7, wherein each of the plurality of hub cannulae has a generally D-shaped cross-section.9. The detachable hub according to claim 7, wherein each of the plurality of hub cannulae has a generally round cross-section.10. The detachable hub according to claim 1, wherein the pivoting locking member comprises a first locking member and a second locking member, and the locking receiver comprises a first locking receiver and a second locking receiver, and wherein the first locking member is engageable with the first locking receiver, and the second locking member is engageable with the second locking receiver.11. A multi-lumen catheter assembly comprising: a distal portion having:a plurality of catheter lumens, wherein each of the plurality of catheter lumens includes a distal tip and a proximal lumen portion; and a distal hub portion slidably disposed over the proximal lumen portion, wherein the distal hub portion includes a pivoting locking member; and a proximal portion having: a plurality of catheter extensions, wherein each of the plurality of catheter extensions fluidly communicates with at least one of the plurality of catheter lumens; and a proximal hub portion having a locking receiver, wherein the pivoting locking member is releasably engaged with the locking receiver. 12. The multi-lumen catheter assembly according to claim 11, wherein, when the pivoting locking member is disengaged from the locking receiver, the distal hub portion is separable from the proximal hub portion.13. The multi-lumen catheter assembly according to claim 12, wherein the plurality of catheter extensions are separable from the plurality of catheter lumens.14. The multi-lumen catheter assembly according to claim 11, wherein the pivoting locking member comprises a cam and wherein the locking receiver comprises a saddle, such that, when the pivoting locking member is engaged with the locking receiver, the cam is engaged with the saddle.15. The multi-lumen catheter assembly according to claim 11, wherein the proximal hub portion further comprises a plurality of hub cannulae wherein each of the plurality of hub cannulae fluidly communicates with one of the plurality of catheter extensions.16. The multi-lumen catheter assembly according to claim 15, wherein each of the plurality of hub cannulae has a generally D-shaped cross-section.17. The multi-lumen catheter assembly according to claim 15, wherein each of the plurality of hub cannulae has a generally round cross-section.18. The multi-lumen catheter assembly according to claim 11, wherein the pivoting locking member comprises a first locking member and a second locking member, and the locking receiver comprises a first locking receiver and a second locking receiver, and wherein the first locking member is engageable with the first locking receiver, and the second locking member is engageable with the second locking receiver.
