- 5. The detachable catheter hub according to claim 1, wherein the first portion of the hub further comprises at least one suture wing extending therefrom.
- 6. The detachable catheter hub according to claim 1, wherein the second portion of the hub further comprises at least one suture wing extending therefrom.
- 7. The detachable catheter hub according to claim 1, wherein the hub further comprises a hub cannula extendable into the at least one catheter lumen.
- 8. The detachable catheter hub according to claim 1, further comprising a suture wing rotatably connected to the second portion and rotatable about a longitudinal axis of the second portion.
- 9. The detachable hub according to claim 8, wherein the suture wing comprises a plurality of suture openings.
- 10. The detachable hub according to claim 1, wherein the first portion further comprises at least one cannula fluidly connecting the distal end to the proximal end, wherein the at least one cannula is integrally formed with the first portion.
- 11. The detachable hub according to claim 10, wherein the first portion and the at least one cannula are a single piece.
- 12. A catheter assembly comprising:
at least one catheter extension tube having a proximal end and a distal end; a hub fluidly connected to the distal end of the catheter extension tube, wherein the hub has a first portion and a second portion releasably connected to the first portion; and at least one catheter lumen releasably connected to the first portion of the hub and fluidly connected to the at least one catheter extension tube, wherein the second portion of the hub is releasably engaged with a proximal end of the at least one catheter lumen and biases the at least one catheter lumen against the first portion of the hub.
- 13. The catheter assembly according to claim 12, wherein the hub further comprises at least one insert extending into the proximal end of the at least one lumen.
- 14. The catheter assembly according to claim 12, further comprising a compression ring disposed within the second portion of the hub, wherein the second portion of the hub biases the compression ring against the proximal end of the lumen.
- 15. The catheter assembly according to claim 12, wherein the first portion of the hub comprises a threaded connection and the second portion of the hub comprises a mating threaded connection.
- 16. The catheter assembly according to claim 12, wherein the first portion of the hub further comprises at least one suture wing extending therefrom.
- 17. The catheter assembly according to claim 12, wherein the secpnd portion of the hub further comprises at least one suture wing extending therefrom.
- 18. The catheter assembly according to claim 12, wherein the at least one catheter lumen comprises a first plurality of catheter lumens and the at least one catheter extension tube comprises a second plurality of extension tubes, such that each of the second plurality of extension tubes is fluidly connected to at least one of the first plurality of catheter lumens.
- 19. The catheter assembly according to claim 18, wherein each of the plurality of catheter lumens is coded to identify the catheter extension tube fluidly connected to each of the plurality of catheter lumens according to a code.
- 20. The catheter assembly according to claim 19, wherein the code is a color code.
- 21. The catheter assembly according to claim 20, wherein the first plurality of catheter lumens comprises a first catheter lumen releasably connected to a second catheter lumen along a longitudinal plane between the first and second catheters.
- 22. A method of replacing a hub on a catheter comprising:
providing a catheter having:
at least one catheter extension tube at a proximal end of the catheter; at least one catheter lumen at a proximal end of the catheter; and a catheter hub fluidly connecting the at least one catheter extension tube to the at least one catheter lumen, wherein the catheter hub comprises:
an old first portion having a proximal end connected to the at least one catheter extension tube and a distal end releasably connected to the at least one catheter lumen; and a second portion releasably connected to the old first portion, wherein the second portion biases the at least one catheter lumen against the old first portion; separating the old first portion of the hub from the second portion; separating the old first portion of the hub from the at least one catheter lumen; installing a new first portion of the hub on the at least one catheter lumen; and securing the second portion of the hub to the new first portion of the hub.
- 23. The method according to claim 20, further comprising, after separating the old first portion of the hub from the at least one catheter lumen, removing the second portion of the hub from the at least one catheter lumen and, prior to installing the new first portion of the hub on the at least one catheter lumen, inserting a new second portion of the hub over the at least one catheter portion, and wherein securing the second portion of the hub to the new first portion of the hub comprises securing the new second portion of the hub to the new first portion of the hub.
- 24. A method of inserting a catheter into a patient comprising:
making an incision through a patient's skin; forming a subcutaneous tunnel under the patient's skin proximate to the incision; inserting a distal end of a catheter into the incision; inserting a proximal end of the catheter through the tunnel away from the incision; connecting a catheter hub to the proximal end of the catheter; and closing the incision.
- 25. The method according to claim 22, further comprising, after connecting the proximal end of the catheter to the catheter hub, securing the catheter hub to the patient's skin.
