Abstract

Antiseptic caps that can be used to disinfect and/or protect medical connectors are disclosed herein. In some embodiments, the antiseptic cap can include a first chamber configured to be removably attached to the medical connector. Delivery systems for use with medical articles are also disclosed herein. In some embodiments, the delivery system comprises various dispensing systems for antiseptic caps and/or antiseptic cap holder assemblies. In some embodiments, the delivery system can be configured to permit the medical articles to be individually removable from the delivery system.

First claim

The following is claimed:

1. A sanitizing cap comprising:
a housing comprising:
a bottom wall, and
a sidewall extending from the bottom wall, the sidewall surrounding an interior chamber and an opening into the interior chamber, the sidewall comprising a non-threaded interior surface extending from the bottom wall, along the sidewall, and to the opening, the interior surface comprising a deformable portion being configured to securely attach to a thread of a medical device;

a cleaning material being configured to releasably retain an antiseptic liquid, the cleaning material being positioned in the interior chamber and being separate from the deformable portion of the interior surface; and
a seal being removably attached to an outer surface of the housing and extending over the interior chamber such that the cleaning material is exposed upon removal of the seal.

2. The sanitizing cap of claim 1 , wherein the deformable portion of the interior surface is configured to securely attach to the medical device such that a fluid tight seal is formed between the deformable portion of the interior surface and the medical device.

3. The sanitizing cap of claim 2 , wherein the fluid tight seal is configured to inhibit release of the antiseptic liquid from the interior chamber.

4. The sanitizing cap of claim 1 , wherein the deformable portion of the interior surface is configured to expand and receive the thread of the medical device when the sanitizing cap is securely attached to the medical device.

5. The sanitizing cap of claim 1 , wherein the deformable portion of the interior surface is configured to securely attach to the thread of the medical device as the sanitizing cap is applied to the medical device in a direction along a longitudinal axis of the sanitizing cap.

6. The sanitizing cap of claim 5 , wherein the deformable portion of the interior surface is configured to securely attach to the thread of the medical device without requiring rotation of the sanitizing cap or the medical device.

7. The sanitizing cap of claim 1 , wherein the deformable portion of the interior surface does not comprise a screw thread.

8. The sanitizing cap of claim 1 , wherein the housing further comprises one or more ribs, and wherein each of the one or more ribs extend at least partially along an external surface of the sidewall.

9. The sanitizing cap of claim 8 , wherein the one or more ribs are configured to facilitate attachment of the sanitizing cap to the medical device.

10. The sanitizing cap of claim 8 , wherein the one or more ribs comprises a plurality of ribs.

11. The sanitizing cap of claim 1 , wherein the housing comprises a ledge configured to retain the cleaning material within the interior chamber.

12. The sanitizing cap of claim 1 , wherein the housing comprises an undercut configured to retain the cleaning material within the interior chamber.

13. The sanitizing cap of claim 1 , wherein the cleaning material is retained within the interior chamber through friction fit.

14. The sanitizing cap of claim 1 , wherein the cleaning material comprises a sponge.

15. The sanitizing cap of claim 1 , wherein the deformable portion of the interior surface is configured to securely attach to the medical device such that a second seal is formed between the deformable portion of the interior surface and the medical device, and wherein the second seal is configured to inhibit release of the antiseptic liquid from the interior chamber,
wherein the deformable portion of the interior surface is configured to expand and receive the thread of the medical device when the sanitizing cap is securely attached to the medical device,
wherein the deformable portion of the interior surface does not comprise a screw thread,
wherein the housing further comprises a plurality of ribs configured to facilitate attachment of the sanitizing cap to the medical device, and wherein each of the plurality of ribs extend at least partially along an external surface of the sidewall,
wherein the cleaning material is retained within the interior chamber through friction fit, and
wherein the cleaning material comprises a sponge.

16. A combination of the sanitizing cap of claim 1 and the medical device.
