Abstract

A multi-port connector such as a closed intravenous (IV) access device with a y-port needle-free connector may be provided. The multi-port connector may include a main housing with a longitudinal axis, a needle free connector disposed along the longitudinal axis, and a y-port extending from a sidewall of the main housing at an angle that is non-parallel with the longitudinal axis. The needle-free connector may include a compressible sealing member that, when compressed opens a first fluid pathway from a first port, through a chamber within the housing, and to an output port. The y-port may be fluidly coupled to the chamber and the output port.

First claim

What is claimed is:

1. A needle-free connector, comprising:
a housing including a first input port at an upper portion of the housing, a second input port extending along an angle from a sidewall of the upper portion of the housing, and an inner surface forming a chamber fluidly coupled to the first input port and the second input port;
a compressible sealing member longitudinally disposed in the chamber and having an uncompressed state in which the compressible sealing member seals the first input port;
a standoff feature extending across an open portion of the sidewall between the chamber and the second input port to resist the compressible sealing member from obstructing the second input port when the compressible sealing member is in a compressed state; and
an output port that is fluidly coupled to the first and second input ports.

2. The needle-free connector of claim 1 , wherein the standoff feature comprises a porous screen having openings to allow fluid flow through the porous screen.

3. The needle-free connector of claim 2 , wherein the porous screen extends from the second input port into the chamber to block or guide movement of the compressible sealing member during compression of the compressible sealing member.

4. The needle-free connector of claim 1 , wherein, when the compressible sealing member is in the compressed state, a continuous fluid pathway is formed between the first input port and the output port.

5. The needle-free connector of claim 4 , wherein the continuous fluid pathway comprises a first continuous fluid pathway and wherein the needle-free connector further comprises a second continuous fluid pathway between the second input port and the output port.

6. The needle-free connector of claim 5 , further comprising a third continuous fluid pathway from the second input port into the chamber that facilitates flushing of the chamber.

7. The needle-free connector of claim 1 , wherein the compressible sealing member forms a compressible sealing member of a positive displacement valve or a negative displacement valve.

8. The needle-free connector of claim 1 , wherein the housing comprises a central elongate portion having a longitudinal axis, wherein the first input port comprises a needle-free valve formed along the longitudinal axis, and wherein the second input port comprises a tubular extension from a sidewall of the central elongate portion.

9. A patient fluid delivery system comprising:
tubing configured to provide a fluid from a fluid source to a patient; and
a needle-free connector configured to couple between the fluid source and the tubing, the needle-free connector comprising:
a housing comprising a sidewall having an inner surface forming a chamber;
a first input port in the housing;
a second input port in the housing;
an output port that is fluidly coupled to the first input port and the second input port;
a compressible sealing member within the chamber, the compressible sealing member having an uncompressed state in which the compressible sealing member seals the first input port and a compressed state that allows a continuous fluid pathway between the first input port and the output port; and
a standoff feature in the housing and extending from the sidewall at the second input port to resist compressible sealing member from obstructing the second input port when the compressible sealing member is in the compressed state.

10. The patient fluid delivery system of claim 9 , wherein, in the uncompressed state, the compressible sealing member forms a planar swabable surface in a common plane with a top surface of the housing.

11. The patient fluid delivery system of claim 9 , wherein the second input port comprises an open Luer access port.

12. The patient fluid delivery system of claim 11 , wherein the open Luer access port comprises a threaded Luer port.

13. The patient fluid delivery system of claim 9 , further comprising a catheter assembly integrally attached to the tubing.

14. The patient fluid delivery system of claim 13 , wherein the catheter assembly comprises a needle hub having a paddle grip, a straight grip, or a ported grip.

15. The patient fluid delivery system of claim 14 , further comprising an end cap configured to seal the second input port.

16. The patient fluid delivery system of claim 9 , further comprising: an antimicrobial coating or an antimicrobial insert ring in the second input port; and an antimicrobial lubricant on the compressible sealing member.
