Claims (28)
1 . A sanitizing cap comprising:
a housing extending between a housing first end and a housing second end, the housing surrounding an interior chamber, the housing second end comprising an opening into the interior chamber, the housing comprising an interior surface extending along a deformable portion lacking an inwardly directed protrusion and 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 second end 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 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 housing.
8 . The sanitizing cap of claim 7 , wherein the one or more ribs are configured to facilitate attachment of the sanitizing cap to the medical device.
9 . The sanitizing cap of claim 7 , wherein the one or more ribs comprises a plurality of ribs.
10 . The sanitizing cap of claim 1 , wherein the housing comprises a ledge configured to retain the cleaning material within the interior chamber.
11 . The sanitizing cap of claim 1 , wherein the housing comprises an undercut configured to retain the cleaning material within the interior chamber.
12 . The sanitizing cap of claim 1 , wherein the cleaning material is retained within the interior chamber through friction fit.
13 . The sanitizing cap of claim 1 , wherein the cleaning material comprises a sponge.
14 . 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 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 housing,
wherein the cleaning material is retained within the interior chamber through friction fit, and
wherein the cleaning material comprises a sponge.
15 . A combination of the sanitizing cap of claim 1 and the medical device.
16 . The sanitizing cap of claim 1 , wherein the housing further comprises a flange extending radially outward from an external surface of the housing.
17 . The sanitizing cap of claim 16 , wherein the flange is positioned a distance from the opening into the interior chamber.
18 . The sanitizing cap of claim 16 , wherein the housing further comprises one or more ribs extending at least partially along an external surface of the housing.
19 . The sanitizing cap of claim 18 , wherein the one or more ribs contact a first surface of the flange.
20 . The sanitizing cap of claim 18 , wherein the one or more ribs extend between the flange and a position proximate the housing first end.
21 . The sanitizing cap of claim 18 , wherein an outer diameter of the flange is greater than an outer diameter of the one or more ribs.
