## Abstract

The present invention relates to a wrap-on finger hook for use with hand splinting devices used in finger rehabilitation programs. The wrap-on finger hook has a finger hook portion that is formed from an ultra thin strapping material, having an exterior grappling surface and an interior non-slip surface. A hook is secured to the exterior surface of wrap-on finger hook for use in selectively attaching tensioning devices to the finger of a human hand. A fastening strap with a loop gender surface is attached to the finger hook portion for releasably fastening the finger hook portion around the finger of a human hand.

## Claims

### Claim 1

A wrap-on finger hook for use with hand splinting devices used in finger rehabilitation programs, comprising:
a) a finger hook portion formed of a thin strapping material, including a tab portion projecting from a wrap around portion with interior and exterior sides;
b) a grappling surface applied to at least a portion of the external side of the finger hook portion formed of one gender of a hook and loop fastening system, and further including a strap connected to the finger hook portion for wrapping around an end portion of a finger and including a portion formed of a second gender of a hook and loop fastening system for engaging said gripping surface;
c) a relatively non-slip surface applied to the interior side of the finger hook portion;
d) a hook means centrally secured to the exterior side of said tab portion, said hook means adapted for use in selectively attaching tensioning devices to the finger of a human hand;
wherein the wrap-on finger hook releasably attaches to the end portion of a finger a human hand for use in a finger rehabilitation program.

### Claim 2 (depends on 1)

The wrap-on finger hook of claim 1, wherein the finger hook portion is formed from an ultra thin strapping material with a high tensile strength, with the exterior side including the loop gender of a hook and loop fastening system.

### Claim 3 (depends on 1)

The wrap-on finger hook of claim 1, wherein the relatively non-slip surface includes a pure PVC compound with a non-migratory plasticizer.

### Claim 4 (depends on 1)

The wrap-on finger hook of claim 1, wherein the hook means includes a #3 metal hook.

### Claim 5

A wrap-on finger hook for use with hand splinting devices used in finger rehabilitation programs, comprising:
a) a finger hook portion formed of an ultra thin strapping material with a high tensile strength having the loop gender of a hook and loop fastening system, said finger hook portion being generally in the shape of a quadrangle centrally positioned above a larger rectangle having an exterior and an interior side;
b) a non-slip surface applied to the interior side of the finger hook portion for providing a counter force to the shear force created by a tensioning device, said non-slip surface formed from a pure PVC compound with a non-migratory plasticizer;
c) a hook centrally secured to the exterior side of the finger hook portion, said hook for use in selectively attaching tensioning devices to an end portion of a finger of a human hand;
d) a fastening strap attached to the finger hook portion for releasably fastening the finger hook portion around the end portion of a finger of a human hand, said fastening strap being formed of a material having the hook gender of a hook and loop fastening system;
wherein the wrap-on finger hook releasably attaches to the end portion of a finger of a human hand for use in a finger rehabilitation program.
