Abstract

A catheter hub is disclosed. The catheter hub includes a first port and a second port fluidly communicating with the first port through a first conduit. The first conduit turns at an angle of greater than approximately 135 degrees between the first port and the second port. The hub also includes a third port fluidly communicating with the second port through a second conduit. The second conduit turns at an angle of greater than approximately 135 degrees between the third port and the second port. Further, the hub includes a fourth port fluidly communicating with the second port. The fourth port and the second port are generally co-axial. A catheter assembly that utilizes the catheter hub is also disclosed.

Claims

5. The catheter hub according to claim 1, wherein the second port comprises a first portion, a second portion, and a third portion;

wherein the first port fluidly communicates with the first portion;

wherein the third port fluidly communicates with the second portion; and

wherein the fourth port fluidly communicates with the third portion.

6. The catheter hub according to claim 1, wherein the second port is adapted to transmit fluid in a plurality of directions.

7. The catheter hub according to claim 6, wherein the second port is adapted to simultaneously transmit fluid in a plurality of directions.

8. A catheter assembly comprising:

a hub having;

a first port;

a second port fluidly communicating with the first port through a first conduit, wherein the first conduit turns at an angle of greater than approximately 135 degrees between the first port and the second port;

a third port fluidly communicating with the second port through a second conduit, wherein the second conduit turns at an angle of greater than approximately 135 degrees between the third port and the second port; and

a fourth port fluidly communicating with the second port, wherein the fourth port and the second port are generally co-axial;
