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.

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.
