Abstract

A compliance assembly includes a compliance strap arranged to engage and extend around the exterior of an orthopedic device, and a compliance clasp attached to the compliance strap. The compliance clasp includes a base member, a door member, and a locking system. The door member is pivotally connected to the base member and is movable between an open position and a closed position in which the door member is rotated toward the base member and locks the compliance strap between the base and door members. The locking system is arranged to irreversibly lock the door member in the closed position.

First claim

The invention claimed is:

1. A compliance assembly for use with an orthopedic device, the compliance assembly comprising:
a compliance strap arranged to engage and extend around an exterior of the orthopedic device; and
a compliance clasp attached to the compliance strap, the compliance clasp including:
a base member;
a door member pivotally connected to the base member, the door member movable between an open position wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and locks the compliance strap between the base and door members; and
a locking system including one or more detents concealed within the compliance clasp when the door member is in the closed position to prevent tampering, wherein the locking system is arranged to irreversibly lock the door member in the closed position so that the compliance clasp is only removable from the compliance strap by breaking at least one of the compliance clasp and the compliance strap.

2. The compliance assembly of claim 1 , wherein the locking system comprises one or more locking grooves on the base member corresponding to the one or more detents.

3. The compliance assembly of claim 2 , wherein the one or more detents engage and lock in the one or more locking grooves when the door member is in the closed position.

4. The compliance assembly of claim 3 , wherein the one or more detents and the one or more locking grooves are concealed within the compliance clasp when the door member is in the closed position.

5. The compliance assembly of claim 3 , wherein the one or more detents are irreversibly locked in the one or more locking grooves when the door member is in the closed position.

6. The compliance assembly of claim 1 , wherein the base member defines a plurality of recesses and the door member defines a plurality of locking members corresponding the recesses.

7. The compliance assembly of claim 6 , wherein the locking members are arranged to penetrate the recesses and lock a portion of the compliance strap within the compliance clasp when the door member is in the closed position.

8. The compliance assembly of claim 6 , wherein at least one of the locking members are arranged to break when a tension is applied to the compliance strap with the door member in the closed position.

9. The compliance assembly of claim 6 , wherein the locking members are formed of a metal material and the door member is formed of a plastic material.

10. The compliance assembly of claim 1 , wherein the one or more detents are formed on and extend from a lower surface of the door member.

11. The compliance assembly of claim 1 , wherein the door member is arranged to at least in part pierce the compliance strap when the door member is in the closed position.

12. The compliance assembly of claim 1 , wherein the compliance clasp comprises a living hinge formed between the base member and the door member.

13. The compliance assembly of claim 1 , wherein the base member defines a first plurality of teeth and the door member defines a second plurality of teeth arranged to engage with the first teeth of the base member when the door member is in the closed position.

14. An orthopedic device comprising:
a base shell having ankle and foot receiving portion, the base shell forming an opening over a dorsal aspect thereof;
a dorsal shell contoured to generally correspond to the opening of the base shell;
a compliance strap arranged to extend over the dorsal shell and around a posterior of the base shell;
a compliance clasp attached to the compliance strap, the compliance clasp including:
a base member;
a door member pivotally connected to the base member, the door member movable between an open position wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and locks the compliance strap between the base and door members; and
a locking system including one or more detents concealed within the compliance clasp when the door member is in the closed position to prevent tampering, wherein the locking system is arranged to irreversibly lock the door member in the closed position so that the compliance clasp is only removable from the compliance strap by breaking at least one of the compliance clasp and the compliance strap.

15. The orthopedic device of claim 14 , wherein the dorsal shell defines a compliance strap guide and the compliance strap extends through the compliance strap guide such that the compliance strap is prevented from being slipped off of the orthopedic device.

16. The orthopedic device of claim 15 , wherein the compliance strap guide is defined on an anterior aspect of the dorsal shell.

17. The orthopedic device of claim 14 , wherein the base member defines a plurality of recesses and the door member defines a plurality of locking members corresponding the recesses.

18. The orthopedic device of claim 17 , wherein the locking members are arranged to penetrate the recesses and lock a portion of the compliance strap within the compliance clasp when the door member is in the closed position.

19. A compliance assembly for use with an orthopedic device including a base shell and a dorsal shell contoured to generally correspond to an opening of the base shell, the compliance assembly comprising:
a compliance strap arranged to engage and extend around a posterior of the base shell and an anterior of the dorsal shell; and
a compliance clasp attached to the compliance strap, the compliance clasp including:
a base member;
a door member pivotally connected to the base member, the door member movable between an open position wherein the door member is rotated away from the base member and the compliance strap is movable between the base and door members, and a closed position, wherein the door member is rotated toward the base member and locks the compliance strap between the base and door members; and
a locking system arranged to irreversibly lock the door member in the closed position so that the compliance clasp is only removable from the compliance strap by breaking at least one of the compliance clasp and the compliance strap, wherein the locking system comprises one or more detents on the door member and one or more locking grooves on the base member corresponding to the one or more detents, the one or more detents being concealed within the compliance clasp when the door member is in the closed position to prevent tampering.
