Abstract

A package for a medical device such as an intermittent catheter has a case with open and closed ends. A hinge connects a cap to the case to permit movement of the cap between open and closed positions. A seal connected to one of the cap and case is engageable with the other to maintain a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap. The case includes a pair of slots at the open end. A pair of latches is formed in the cap. The latches fit into the slots to prevent lateral forces from distorting the cap when the cap is closed. A first use indication label spans a depression in the outer contour of a closed cap and case, assuring visual confirmation of breach of the label upon first opening of the cap.

First claim

What is claimed is:

1. A medical device package, comprising:
a case having a tubular wall which is closed at one end and open at the other end, said other end of the tubular wall defining a top land and an outer surface adjacent the top land, said outer surface of the tubular wall having an outer dimension;
a cap having a top wall and a side wall, said side wall defining a bottom land and an outer surface adjacent the bottom land, said outer surface of the side wall having an outer dimension that matches the outer dimension of the tubular wall;
a hinge having one end connected to the cap and a second end connected to said other end of the tubular wall, the hinge permitting selectable movement of the cap between an open position, wherein access is provided to the open end of the tubular wall, and a closed position, wherein the cap prevents access to the open end of the tubular wall, the bottom land of the closed cap together with the top land of the case defining a junction line where the cap and case are adjacent one another when the cap is closed;
an indentation in one of the outer surfaces, the indentation having a reduced outer dimension compared to the rest of the outer surface in which it is formed; and
a first use indication label affixed to the cap and case so as to span the junction line with at least a portion of the label disposed opposite said indentation and at least a portion of the label spanning the indentation.

2. The medical device package of claim 1 further comprising a seal connected to at least one of the cap and case, the seal being engageable with the other of the cap and case when the cap is in the closed position to form a barrier between the cap and case that maintains a sterile environment inside the case and cap.

3. The medical device package of claim 1 wherein the case includes a projection at the open end of the case, the projection having a cylindrical exterior, and the cap includes a shell having a cylindrical interior that receives the projection therein when the cap is in the closed position.

4. The medical device package of claim 3 further comprising a seal connected to the exterior of the projection where the seal is engageable with the interior of the shell portion when the cap is in the closed position.

5. The medical device package of claim 1 further comprising at least one latch formed on one of the case and cap; and
at least one slot formed in the other of the case and cap, the at least one latch and at least one slot being engageable with one another when the cap is closed.

6. The medical device package of claim 5 wherein the at least one latch has at least one undercut, each undercut defines a respective tab.

7. The medical device package of claim 6 wherein the at least one slot defines at least one ear, the tab and at least one ear being disposed so as to flex past one another during an opening or closing movement of the cap.

8. The medical device package of claim 7 wherein the at least one latch further comprises at least a first latch and a second latch and each latch has an undercut which defines a pair of tabs; and
wherein the at least one slot further comprises at least a first slot and a second slot which together with the first slot defines a detent having a pair of ears, the tabs and ears being disposed so as to flex past one another during an opening or closing movement of the cap.

9. The medical device package of claim 1 further comprising a hydration liner having a seat sized to engage the internal surface of the tubular wall of the case, the hydration liner further including a hollow tube attached to the seat and extending therefrom to an open end, the hollow tube having an outside diameter less than the internal diameter of the tubular wall of the case.

10. The medical device package of claim 1 further comprising at least one rib formed on and extending radially from the interior of the tubular wall, the rib being disposed in a circumferential location near the open end of the tubular wall where the rib is engageable with a medical device in the package to prevent tilting of the medical device away from the hinge and to a position where it could interfere with closing of the cap.

11. The medical device package of claim 1 , wherein the cap further comprises a lip on the cap at the intersection of the top wall and side wall.

12. A medical device package, comprising:
a case having a hollow tubular wall which defines an interior and an axis and is closed at one end, the other end of the tubular wall extending to a collar which terminates at a top land to define an open end of the collar, the top land having an external shape and dimension;
a cap having a side wall which defines an interior of the cap and terminates at a bottom land, the bottom land having an external shape and dimension which matches that of the top land;
a hinge having one end connected to the cap and a second end connected to said collar, the hinge permitting selectable movement of the cap between an open position, wherein access is provided to the open end of the collar, and a closed position, wherein the cap prevents access to the open end of the collar and wherein the top and bottom lands engage one another in facing relation;
an indentation in one of the cap or case, the indentation adjoining the land of said one of the cap or case to provide a reduced external dimension compared to the rest of the land to which it adjoins; and
a first use indication label affixed to the cap and case with at least a portion of the label disposed opposite said indentation and at least a portion of the label spanning the indentation.

13. The medical device package of claim 12 further comprising a seal connected to at least one of the cap and case, the seal being engageable with the other of the cap and case when the cap is in the closed position to form a barrier between the cap and case that maintains a sterile environment inside the case and cap.

14. The medical device package of claim 12 wherein the case includes a projection at the open end of the case, the projection having a cylindrical exterior, and the cap includes a shell having a cylindrical interior that receives the projection therein when the cap is in the closed position.

15. The medical device package of claim 14 further comprising a seal connected to the exterior of the projection where the seal is engageable with the interior of the shell portion when the cap is in the closed position.

16. The medical device package of claim 12 further comprising at least one latch formed on one of the case and cap; and
at least one slot formed in the other of the case and cap, the at least one latch and the at least one slot being engageable with one another when the cap is closed.

17. The medical device package of claim 16 wherein the at least one latch has at least one undercut, each undercut defines a respective tab.

18. The medical device package of claim 17 wherein the at least one slot defines at least one ear, the tab and at least one ear being disposed so as to flex past one another during an opening or closing movement of the cap.

19. The medical device package of claim 18 wherein the at least one latch further comprises at least a first latch and a second latch and each latch has an undercut which defines a pair of tabs; and
wherein the at least one slot further comprises at least a first slot and a second slot which together with the first slot defines a detent having a pair of ears, the tabs and ears being disposed so as to flex past one another duri
