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 (22)

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

a body comprising a first port, a second port, and a third 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 third port than the second end of the fluid diverter; and

the connector, wherein the connector is positioned proximate the third port and at least partially surrounds the fluid diverter, the 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;

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 third 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 the wall of the internal projection member, the second opening comprising 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, wherein a first axis extending through a center of the first opening is non-parallel to a second axis extending through a center of the second opening;

wherein the fluid diverter extends at least partially into the internal cavity defined by the wall of the internal projection member such that 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.

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 branched medical connector.

10. The multi-port branched medical connector of claim 1 , wherein the seal member has a second position facilitating flow through the first end of the housing.

11. The multi-port branched medical connector of claim 10 , wherein, in the second position, the first end of the seal member is closer to the second end of the housing than when in the first position.
