Abstract

A luer cleaner (100) including a generally hollow body (112) having an open first end (104), a closed second end (106), and a longitudinal axis extending therethrough between the first end and the second end. The first end (104) is sized to receive therein a luer connector (190) proximal end and includes a plurality of bristles (134) extending generally toward the longitudinal axis sufficiently to engage the outer surfaces of the luer proximal end disposed therein. The second end comprises a compressible reservoir (166) containing a fluid (168), wherein, when the second end is compressed, the fluid is transmitted from the reservoir toward the first end through passageways to wet the luer proximal end. A method for cleaning luer connectors is also disclosed.

wherein the scrubber includes at least one longitudinally extending through-passage therealong in fluid-receiving communication with the second end and adjacent to an interior surface of the cylindrical wall and has a diameter less than that defined by the luer-receiving cavity, and that is in communication with the interior of the scrubber to wet the scrubber upon compression of the compressible reservoir, for cleaning the luer.

2. The luer cleaner according to claim 1, wherein the fluid is an antiseptic fluid.

3. The luer cleaner according to claim 1, wherein the scrubber comprises at least one ring disposed in the first end, and wherein a plurality of flexible, generally pointed projections extend from the at least one ring radially inwardly toward the longitudinal axis for engaging the luer.

4. The luer cleaner according to claim 3, wherein the at least one ring comprises a plurality of rings.

5. The luer cleaner according to claim 1, wherein the reservoir is defined within an initially separate compressible body joined to the hollow cleaner body remote from the open first end.

6. The luer cleaner according to claim 5, wherein the separate compressible body further comprises a collar disposed thereon forwardly of the reservoir, for being joined sealingly with the hollow cleaner body, the collar including a small diameter aperture therethrough for transmission of fluid into the open first end of the cleaner body.

7. The luer cleaner according to claim 1, wherein the body further comprises an exterior portion, wherein the exterior portion comprises a plurality of ribs spaced about the periphery thereof and extending therefrom, away from the longitudinal axis.

8. The luer cleaner according to claim 1, further comprising a centering post disposed along the longitudinal axis and within the open first end, complementary to the open proximal end of a luer and that closes the open proximal end upon full insertion of the luer proximal end into the open first end of the hollow body.

9. The luer cleaner according to claim 1, wherein the fluid is retained in a frangible capsule within the compressible reservoir.

10. The luer cleaner according to claim 1, wherein the fluid is retained in two frangible capsules within the compressible reservoir, separated from each other by a tab having a channel extending forwardly toward the luer first end.

11. The luer cleaner according to claim 6, wherein, in the absence of compression of the reservoir, the fluid is sufficiently viscous to remain within the reservoir.

15. The luer cleaner according to claim 4, wherein the at least one longitudinal through-passage comprises co-aligned openings through the plurality of rings adjacent the interior of the cylindrical wall.

16. The luer cleaner according to claim 15, wherein transverse surfaces of the plurality of rings comprise channels that extend radially inwardly from the co-aligned openings.

17. The luer cleaner according to claim 1, wherein the scrubber includes at least one alignment post extending radially outwardly and insertable into and along a respective at least one alignment notch in the hollow body.

18. The luer cleaner according to claim 1, further including a cap affixed onto an entrance to the open first end for assuredly maintaining the scrubber in the hollow body.

23. The cleaner according to claim 1, further comprising sealing ring traversing the open end having a circular opening sufficiently large in diameter to permit insertion therethrough of a luer proximal end and adapted to seal against the exterior of the luer upon insertion into the open end.

12. A method of cleaning a luer comprising the steps of:

(a) providing a luer cleaner comprising;

a generally hollow body having an open first end, a closed second end, and a longitudinal axis extending therethrough between the first end and the second end, wherein the first end is sized to receive therein a luer, wherein the first end includes a centering post extending axially from the second end toward the open first end to receive the luer therearound upon luer insertion and close off the luer interior, and wherein the first end includes a plurality of flexible, generally pointed projections extending generally toward the centering post sufficiently to engage the luer disposed therearound; and

wherein the second end comprises a compressible reservoir adapted to receive and retain a fluid, wherein, when the second end is compressed, the fluid is transmitted toward the first end;

(b) inserting a luer into the open end and over and around the centering post and becoming centered thereby with its interior closed off, wherein the plurality of flexible projections engage an exterior of the luer; and

(c) compressing the second end and transmitting the fluid to the luer and to the plurality of flexible projections.

13. The method according to claim 12, further comprising rotating the luer about the centering post thereby scrubbing the luer exterior.

14. The method according to claim 13, wherein rotating the luer about the centering post further comprises reciprocally rotating the luer in each of two directions.

19. A cleaner for cleaning a medical article, comprising:

a generally hollow body having a first end, a second end, and a longitudinal axis extending therethrough between the first end and the second end, wherein the first end includes a cylindrical wall that is sized to receive therein a medical device; and

a plurality of scrubber rings disposed in the body, each scrubber ring having a peripheral body and a plurality of flexible non-abrasive projections directed radially inwardly and concluding in points for engaging outer surfaces of a medical article when the medical article is inserted into the body whereby the outer surfaces of the medical article are non-abrasively scrubbed when the medical article is reciprocally moved at least axially relative to the body.

20. The cleaner of claim 19, wherein the hollow body includes at least one alignment notch extending longitudinally along an inside surface thereof, and each scrubber ring includes a corresponding at least one alignment post extending radially outwardly therefrom to be insertable into and along the at least one alignment notch.

21. The cleaner according to claim 19, further comprising a centering post disposed along the longitudinal axis and within the hollow body, complementary to an open proximal end of a luer and that closes the open proximal end upon full insertion of the luer proximal end into the hollow body.

22. The cleaner according to claim 19, further comprising an apertured sealing ring traversing the open end adapted to seal against the exterior of the luer upon insertion into the open end.

24. A method of cleaning a luer comprising the steps of:

(a) providing a luer cleaner comprising;

a generally hollow body having a first end opened and sized to receive thereinto a luer, a closed second end, a longitudinal axis extending therethrough between the first end and the second end, a cleaning fluid within the hollow body and at least accessible to the first end, a non-abrasive scrubber within the first end engageable with outer surfaces of a luer inserted into the first end and being at least accessible to the cleaning fluid, and a centering structure within the first end extending axially away from the closed second end for being received into a complementary opening of the luer;

(b) inserting a luer into and centered within the open end such that the scrubber is in engagement with at least an exterior of the luer; and

(c) rotating the luer, the scrubber thereby scrubbing the luer exterior in association with the cleaning fluid.

25. A device for cleaning a medical article, comprising:
