Abstract

A disinfecting and pre-opening device is disclosed for use with a female needleless connector. The disinfecting and pre-opening device includes a housing comprising a chamber having a distal opening and configured to fit over the female needleless connector, and an elongated finger attached to the housing and disposed within the chamber such that the elongated finger opens the fluid path through the female needleless connector when the distal opening of the disinfecting and pre-opening device is placed proximally adjacent to the septum and the disinfecting and pre-opening device is advanced in the distal direction.

Claims (21)

1. A device for use with a female needleless connector, the device comprising:

a housing having a proximal wall, a side-wall, a distal opening, and a chamber, the chamber extending between an inner surface of the side-wall and the proximal wall through the distal opening;

an elongate finger within the chamber and extending from the proximal wall toward the distal opening, an outer surface of the elongate finger comprising an undercut having a first end at the proximal wall and a second end adjacent a distal end portion of the elongate finger; and

a fluid-absorbing matrix within the chamber, the fluid-absorbing matrix having a first portion extending along the inner surface of the side-wall, and a second portion extending within the undercut, from the first end to an end of the fluid-absorbing matrix at the second end of the undercut; wherein the distal opening is configured to fit over a proximal end of the female needleless connector.

2. The device of claim 1 , wherein the fluid-absorbing matrix contains a disinfectant.

3. The device of claim 1 , wherein the first portion of the fluid-absorbing matrix is configured to create a removable interference fit with an external surface of the female needleless connector.

4. The device of claim 1 , wherein the second portion of the fluid-absorbing matrix extends along the outer surface of the elongate finger.

5. The device of claim 1 , wherein a third portion of the fluid-absorbing matrix extends along an inner surface of the proximal wall.

6. The device of claim 1 , further comprising a vapor barrier lid removably sealed across the distal opening of the chamber.

7. The device of claim 1 , wherein the side-wall extends beyond the distal end portion of the elongate finger.

8. The device of claim 1 , wherein a cross-sectional width of the elongate finger tapers away from the proximal wall.

9. The device of claim 1 , wherein the distal end portion of the elongate finger comprises a rounded outer surface.

10. The device of claim 1 , wherein the housing comprises a neck extending from the proximal wall in a direction that is opposite to a direction that the elongate finger extends from the proximal wall, an inner surface of the neck forming a second chamber configured to removably couple to a male needleless connector.

11. The device of claim 10 , further comprising a sealing layer on an inner surface that forms the second chamber.

12. The device of claim 11 , wherein the sealing layer extends along the proximal wall.

13. A device for use with a female needleless connector, the device comprising:

a housing having a proximal wall, a side-wall, a distal opening, and a chamber, the chamber extending between an inner surface of the side-wall and the proximal wall through the distal opening;

an elongate finger within the chamber and extending from the proximal wall toward the distal opening, an outer surface of the elongate finger comprising an undercut having a first end at the proximal wall and a second end adjacent a distal end portion of the elongate finger; and

a fluid-absorbing matrix within the chamber, wherein a first portion of the fluid-absorbing matrix extends along the proximal wall, a second portion of the fluid-absorbing matrix extends along the inner surface of the side-wall and away from the first portion, and a third portion of the fluid-absorbing matrix extends within the undercut to terminate at the second end of the undercut.

14. The device of claim 13 , wherein a thickness of the second portion of the fluid-absorbing matrix tapers toward the distal opening.

15. The device of claim 13 , wherein a thickness of the third portion of the fluid-absorbing matrix tapers toward the distal end portion of the elongate finger.
