Abstract

A removable hub for a catheter is disclosed. The catheter hub includes a lower portion having a lower proximal end, a lower distal end, and a lower channel extending between the lower proximal end and the lower distal end. The catheter hub further includes an upper portion having an upper proximal end, an upper distal end, and an upper channel extending between the upper proximal end and the upper distal end. The catheter hub further includes a hinge connecting the lower portion and the upper portion and a lock for releasably securing the lower portion and the upper portion to each other, distal from the hinge. When the lower portion is releasably secured to the upper portion, the lower channel and the upper channel form a passageway.

means for releasably securing the lower portion and the upper portion to each other, distal from the hinge,

wherein, when the lower portion is releasably secured to the upper portion, the lower distal channel and the upper distal channel form a distal passageway, the first lower proximal channel and the first upper proximal channel form a first proximal passageway and the second lower proximal channel and the second upper proximal channel form a second proximal passageway.

2. The catheter hub according to claim 1, wherein the hinge is disposed between the first and second lower proximal channels.

3. The catheter hub according to claim 1, wherein at least one of the lower and upper portions comprises means for releasably securing the hub to a body.

4. The catheter hub according to claim 1, wherein the lower portion and the upper portion are releasably secured to each other by an interlocking engagement between the lower portion and the upper portion.

5. The catheter hub according to claim 1, wherein the lower portion comprises at least one of a locating pin and a like number of recesses, wherein the upper portion comprises the other of the at least one locating pin and the like number of recesses, and wherein, when the lower portion is releasably secured to the upper portion, each of the at least one pin is disposed within a respective one of each of the like number of recesses.

6. The catheter hub according to claim 1, wherein the hinge is a living hinge.

7. The catheter hub according to claim 1, wherein the catheter hub is constructed from polypropylene.

8. The catheter hub according to claim 1, wherein the distal passageway fluidly communicates with each of the first and second proximal passageways.

9. The catheter hub according to claim 1, further comprising at least one suture wing extending from at least one of the lower portion and the upper portion.

10. The catheter hub according to claim 1, wherein a first catheter lumen is disposable in the first proximal passageway and the distal passageway, and wherein a second catheter lumen is disposable in the second proximal passageway and the distal passageway.

11. A catheter hub comprising:
