Abstract

A medical connector for use in a fluid pathway. A valve member with sealing rings helps preclude undesired accumulation of fluid within the connector. A branched connector includes a fluid diverter extending away from a port of the branched connector. The fluid diverter is configured to divert fluid flowing through the branched connector and into a medical connector attached thereto, flushing a distal portion of the medical connector.

Claims (18)

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

a body comprising a first port, a second port, and a third port, wherein the third port is positioned between the first and second ports;

a fluid diverter extending away from the third port; and

the needleless connector at the third port and at least partially surrounding the fluid diverter, the needleless connector comprising:

a connector housing having a first end and a second end, the first end distal the second end;

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

an internal projection member positioned at least partially within the compressible seal, the internal projection member having walls that define an internal cavity that encompasses the fluid diverter, an opening at a proximal end of the internal projection member, and at least one distal opening to an internal cavity of the compressible seal at a distal end of the internal projection member, the at least one distal opening having a proximal surface and a distal surface and being in fluid communication with the compressible seal;

wherein the fluid diverter extends at least partially into the compressible seal, and wherein the fluid diverter has a profile, the profile of the fluid diverter adapted to track the walls of the internal cavity of the internal projection member in a distal direction a distance past the proximal surface of the at least one distal opening to effect flushing of the internal projection member at the distal end of the internal projection member.

2. The multi-port branched medical connector of claim 1 , wherein the fluid diverter bifurcates the internal cavity of the internal projection member at the proximal end of the internal projection member.

3. The multi-port branched medical connector of claim 1 , wherein the fluid diverter substantially bifurcates at least about half of the internal cavity of the internal projection member.

4. The multi-port branched medical connector of claim 3 , wherein the fluid diverter substantially bifurcates at least about three quarters of the internal cavity of the internal projection member.

5. The multi-port branched medical connector of claim 1 , wherein the fluid diverter has a distal tip that extends within the internal projection member to at least the proximal surface of the at least one distal opening.

6. The multi-port branched medical connector of claim 1 , wherein the compressible seal has a plurality of sealing rings on an interior surface thereof, the plurality of sealing rings configured to contact and seal against the internal projection member.

7. The multi-port branched medical connector of claim 6 , wherein at least one sealing ring of the plurality of sealing rings contacts the internal projection member above the at least one distal opening and at least one sealing ring of the plurality of sealing rings contacts the internal projection member below the at least one distal opening.

8. The multi-port branched medical connector of claim 6 , wherein a height of the internal projection member from the distal surface of the at least one distal opening to an upper tip of the internal projection member is greater than or equal to a height of the internal cavity of the compressible seal from an uppermost sealing ring to an uppermost surface of the internal cavity.

9. The multi-port branched medical connector of claim 1 , wherein the fluid diverter and the internal projection member are integrally formed.

10. The multi-port branched medical connector of claim 5 , wherein the distal tip of the fluid diverter extends within the internal projection member to a position past the proximal surface of the at least one distal opening.

11. The multi-port branched medical connector of claim 1 , wherein the fluid diverter has a distal tip, the profile of the fluid diverter being widest at a proximal end of the fluid diverter and narrower towards the distal tip.
