Abstract

Various embodiments of an antimicrobial insert for a stopcock medical connector are provided. More specifically, the present invention relates to an antimicrobial insert that is seated within at least a portion of the annular bore of the connector's tap, wherein fluid within the annular bore contacts the antimicrobial insert, thereby preventing microbial proliferation within the stopcock medical connector.

First claim

The invention claimed is:

1. A stopcock medical connector device, comprising:
a housing having a proximal opening, a distal end, and an inner lumen extending therebetween, the housing further comprising a plurality of side ports extending outwardly from the inner lumen, each side port having a hollow interior in fluid communication with the inner lumen;
a tap rotatably seated in the inner lumen of the housing and comprising an annular bore forming a fluid pathway through a shaft portion of the tap, wherein the tap is rotated within the inner lumen to align the plurality of side ports with the annular bore to provide fluid communication between the plurality of side ports and the annular bore; and
an antimicrobial insert seated within the annular bore in proximity to the inner lumen, wherein the antimicrobial insert comprises an annular ring having an inner circumference and an outer circumference, wherein the inner circumference defines an opening that extends through the annular ring, wherein the tap is rotated within the inner lumen to align the plurality of side ports with the annular bore and the opening, wherein the fluid pathway comprises the opening.

2. The device of claim 1 , wherein the plurality of side ports each comprise an inner diameter that is less than the outer circumference, and greater than the inner circumference of the antimicrobial insert.

3. The device of claim 2 , further comprising a plurality of annular bores.

4. The device of claim 1 , wherein the antimicrobial insert is a first antimicrobial insert, further comprising a second antimicrobial insert, wherein the second antimicrobial insert comprises an annular ring having an inner circumference, wherein the inner circumference of the second antimicrobial insert defines an opening that extends through the annular ring of the second antimicrobial insert, wherein the tap is rotated within the inner lumen to align the plurality of side ports with the annular bore, the opening that extends through the annular ring of the first antimicrobial insert, and the opening that extends through the annular ring of the second antimicrobial insert, wherein the fluid pathway further comprises the opening that extends through the annular ring of the second antimicrobial insert.

5. The device of claim 1 , wherein the antimicrobial insert comprises a three-dimensional matrix forming a frame structure having a plurality of apertures.

6. The device of claim 5 , wherein the antimicrobial insert is comprised of an antimicrobial material.

7. The device of claim 5 , wherein the antimicrobial insert is coated with an antimicrobial material.

8. The device of claim 1 , wherein an outer diameter of the annular ring is approximately equal to or larger than a diameter of the annular bore such that the annular ring is retained within the annular bore in a friction fit.

9. A method for manufacturing a stopcock medical connector device, the method comprising steps for:
providing a housing having a proximal opening, a distal end, and an inner lumen extending therebetween, the housing further comprising a plurality of side ports extending outwardly from the inner lumen, each side port having a hollow interior in fluid communication with the inner lumen;
rotatably seating a tap in the inner lumen of the housing, the tap comprising an annular bore forming a fluid pathway through a shaft portion of the tap, wherein the tap is rotated within the inner lumen to align the plurality of side ports with the annular bore to provide fluid communication between the plurality of side ports and the annular bore; and
inserting an antimicrobial insert within the annular bore and in proximity to the inner lumen, wherein the antimicrobial insert comprises an annular ring having an inner circumference, wherein the inner circumference defines an opening that extends through the annular ring, wherein the fluid pathway comprises the opening.

10. The method of claim 9 , wherein the antimicrobial insert comprises an annulus shape having an outer circumference defining an outer surface, and an inner circumference defines a fluid pathway through the antimicrobial insert, wherein the annular bore is in fluid communication with the plurality of side ports via the fluid pathway of the antimicrobial insert.
