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 (23)

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

a housing comprising:

a chamber having a proximal wall;

a side-wall extending from the proximal wall toward a distal opening configured to fit over a proximal end of the female needleless connector; and

an elongate finger extending within the chamber from the proximal wall toward the distal opening,

wherein an outer surface of the elongate finger comprises an undercut that extends from the proximal wall toward the distal end of the elongate finger, and

wherein the side-wall extends beyond a distal end of the elongate finger such that the elongate finger extends into and opens a fluid path through the female needleless connector when the distal opening is distally advanced over the female needleless connector.

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

3. The device of claim 1 , wherein an inner surface of the side-wall comprises a portion of a fluid-absorbing matrix that contains a disinfectant.

4. The device of claim 1 , wherein an outer surface of the elongate finger comprises a portion of a fluid-absorbing matrix that contains a disinfectant.

5. The device of claim 1 , wherein an inner surface of the proximal wall comprises a portion of a fluid-absorbing matrix that contains a disinfectant.

6. The device of claim 1 , wherein a portion of an inner surface of the side-wall comprises a lining configured to create a removable interference fit with an external surface of the female needleless connector.

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

8. The device of claim 1 , wherein the side-wall tapers toward the proximal wall.

9. The device of claim 1 , wherein the housing comprises a second chamber and a neck extending from the proximal wall in a direction opposite the side-wall, wherein the neck is sized and configured to removably couple to a male needleless connector.

10. The device of claim 9 , wherein a sealing layer is positioned adjacent the proximal wall within the second chamber.

11. A method of disinfecting and pre-opening a female needleless connector comprising:

placing a distal opening of a housing adjacent to a proximal end of a female needleless connector, wherein the housing comprises a chamber having a proximal wall, a side-wall extending from the proximal wall toward the distal opening, a matrix containing a disinfectant, and an elongate finger extending within the chamber from the proximal wall toward the distal opening, wherein an outer surface of the elongate finger comprises an undercut that extends from the proximal wall toward the distal end of the elongate finger, and wherein the side-wall extends beyond a distal end of the elongate finger;

moving the housing in a distal direction such that the side-wall extends over a proximal end of the female needleless connector; and

advancing the housing in the distal direction such that the matrix contacts a septum of the female needleless connector and the elongated finger opens a fluid path through the female needleless connector.

12. The method of claim 11 , comprising retracting the housing in a proximal direction to remove the housing from the female needleless connector.

13. The method of claim 11 , comprising removing a portion of a lid that is removably sealed across the distal opening.

14. The method of claim 11 , comprising removing the housing from a male needleless connector.
