Abstract

Devices and methods for sterilizing the outer and inner surfaces of a working end-site of a medical device such as a catheter hub, luer connector, luer component, needleless access site, and/or access port are discussed. The sterilizing device can include a housing, a sterilizing element including an antipathogenic agent configured for sterilizing the working end-site of a medical device, and a cap hingedly coupled to the housing and configured to hermetically seal the sterilizing element within the housing. One or more features on the cap and housing serve to hermetically seal the cap to the housing prior to use.

Claims

1. A contoured sterilizing element for sterilizing a working end-site of a medical device, the sterilizing element comprising:

a first member including an antipathogenic agent, the first member further including a first contoured inwardly facing surface and a first opening, wherein the first contoured inwardly facing surface comprises a first plurality of inwardly projecting contouring members, wherein at least one of the first plurality of inwardly projecting contouring members is porous and impregnated with the antipathogenic agent, wherein the first plurality of inwardly projecting contouring members includes all projections on the first member;

a second member including the antipathogenic agent, the second member further including a second contoured inwardly facing surface and a second opening, wherein the second contoured inwardly facing surface comprises a second plurality of inwardly projecting contouring members, wherein at least one of the second plurality of inwardly projecting contouring members is porous and impregnated with the antipathogenic agent, wherein the first member is coupled to the second member, wherein the second plurality of inwardly projecting contouring members includes all projections on the second member; and

a base member including the antipathogenic agent and a contoured inwardly facing surface, wherein the inwardly facing surface comprises a third plurality of inwardly projecting contouring members, wherein at least one of the third plurality of inwardly projecting contouring members is porous and impregnated with the antipathogenic agent, wherein the base member is coupled to the second member to form a bottom surface under the first and second openings such that the first contoured inwardly facing surface, the second contoured inwardly facing surface and the contoured inwardly facing surface of the base member form a contoured cavity, wherein the contoured cavity is configured to receive the working end-site of the medical device, wherein the third plurality of inwardly projecting contouring members includes all projections on the base member;

wherein the contoured cavity tapers in an inward direction from the first opening in the first member toward the bottom surface; and

wherein the first plurality of inwardly projecting contouring members is rotationally offset from the second plurality of inwardly projecting contouring members such that radial locations of the first plurality of inwardly projecting contouring members are different than radial locations of the second plurality of inwardly projecting contouring members.

2. The sterilizing element of claim 1, wherein the first opening forms a contoured pattern.

3. The contoured sterilizing element of claim 1, wherein the contoured cavity forms a concentric contoured and tapered opening.

4. The contoured sterilizing element of claim 1, wherein at least one of the first, second, and base members comprises a porous material with capillarity that is configured to maintain distribution of the antipathogenic agent throughout an entirety of the material.

5. The contoured sterilizing element of claim 1, wherein at least one of the first member, the second member, and the base member comprises nanoparticles bonded to a micro-contour, wherein the nanoparticles are configured to enhance sterilizing action of the at least one of the first member, the second member, and the base member.

6. The sterilizing element of claim 1, wherein at least one of the first member, second member and base member is constructed of an absorbent material.

7. The sterilizing element of claim 6, wherein at least two of the first member, second member and base member are constructed of an absorbent material.

8. A contoured sterilizing element for sterilizing a working end-site of a medical device, the sterilizing element comprising:

a set of members coupled to each other and including an antipathogenic agent, wherein each member of the set of members includes a plurality of inwardly projecting structures, wherein at least one of the plurality of inwardly projecting structures from each member of the set of members is absorbent and impregnated with the antipathogenic agent;

wherein a first member of the set of members includes an opening configured to receive the working end-site of the medical device and a second member of the set of members is a base member positioned at the bottom of the set of members under the opening to form a continuous closed bottom surface; and

wherein the plurality of inwardly projecting structures from each member of the set of members and the continuous closed bottom surface defines an inner surface of a cavity.

9. The sterilizing element of claim 8, wherein the pluralities of inwardly projecting structures are spaced and varied along the cavity.

10. The sterilizing element of claim 8, wherein the cavity has an inner diameter configured to be less than an outer diameter of the working end-site.

11. The sterilizing element of claim 8, further comprising a housing within which the set is disposed, wherein the set is removable from the housing to permit a user to hold the set to disinfect the working end-site and fingers of the user.

12. The sterilizing element of claim 8, further comprising a housing within which the set is disposed, wherein the set is configured so as to be removable from the housing while attached to the end-site.

13. The sterilizing element of claim 8, wherein the plurality of inwardly projecting structures include micro-structures including one or more of ridges, bumps, dimples, surface roughing, rings, concentric circles, and lattice features.

14. The sterilizing element of claim 8, wherein the sterilizing element is configured to sterilize an end-site having a lumen and a septum.

15. The sterilizing element of claim 8, wherein the inner surface is configured to engage and disinfect an inner surface of the end-site.

16. The sterilizing element of claim 8, wherein at least one member of the set of members is constructed of a porous material.

17. The sterilizing element of claim 16, wherein at least two of the members of the set of members is constructed of a porous material.

20. The sterilizing element of claim 8, wherein the one member comprises a side wall, wherein the side wall comprises a surface, and a plurality of outwardly projecting structures extending from the side wall.

18. The sterilizing element of 8, wherein the one member is oriented along an interior side and the plurality of inwardly projecting structures from the one member extend from the interior side.

19. The sterilizing element of 18, wherein the inwardly projecting structures of the base member project toward the opening.
