Abstract

Claims (21)

1. A multi-port branched medical connector adapted for flushing a needleless connector on one port of the multi-port branched medical connector, the multi-port branched medical connector comprising:

a body comprising a first port and a second port;

a fluid diverter comprising a first end and a second end, wherein the first end of the fluid diverter is positioned closer to the first port than the second end of the fluid diverter; and

the needleless connector, wherein the needleless connector is positioned proximate to the first port and at least partially surrounds the fluid diverter, the needleless connector comprising:

a housing comprising a first end and a second end opposite the first end;

a seal member positioned at least partially within the housing and configured to impede flow through the first end of the housing when in a first position; and

an internal projection member positioned at least partially within the seal member, the internal projection member comprising:

a first end and a second end opposite the first end, the first end of the internal projection member positioned closer to the first port than the second end of the internal projection member;

a wall defining an internal cavity that at least partially encompasses the fluid diverter;

a first opening at the first end of the internal projection member; and

a second opening, the second opening extending through a lateral portion of the wall of the internal projection member, wherein the second opening comprises a proximal surface and a distal surface, the proximal surface positioned a first distance from the first end of the internal projection member and the distal surface positioned a second distance from the first end of the internal projection member, the second distance being greater than the first distance, and wherein the second end of the fluid diverter is positioned a third distance from the first end of the internal projection member, the third distance being greater than the first distance that the proximal surface of the second opening is spaced from the first end of the internal projection member;

wherein the fluid diverter extends at least partially into the internal cavity defined by the wall of the internal projection member to effect flushing of the second end of the internal projection member.

2. The multi-port branched medical connector of claim 1 , wherein the third distance is less than the second distance.

3. The multi-port branched medical connector of claim 1 , wherein the second opening is positioned closer to the second end of the internal projection member than to the first end of the internal projection member.

4. The multi-port branched medical connector of claim 1 , wherein the internal projection member further comprises a third opening extending through the wall of the internal projection member, wherein the third opening is aligned with the second opening.

5. The multi-port branched medical connector of claim 1 , wherein the internal projection member further comprises a tip extending from the second end of the internal projection member toward the first end of the internal projection member.

6. The multi-port branched medical connector of claim 5 , wherein the tip of the internal projection member extends from the second end of the internal projection member to the second opening.

7. The multi-port branched medical connector of claim 1 , wherein the fluid diverter bifurcates at least half of the internal cavity defined by the wall of the internal projection member.

8. The multi-port branched medical connector of claim 1 , wherein at least a portion of a length of the fluid diverter is configured to track a profile of the wall of the internal projection member.

9. The multi-port branched medical connector of claim 1 , wherein the fluid diverter is integral with the body of the multi-port branched medical connector.

10. The multi-port branched medical connector of claim 1 , wherein the second end of the internal projection member is closed.
