Abstract
Abstract Digital and metacarpal splint apparatus wherein an elongate splint member is adjustably positionable into anatomical alignment with any one of the fingers of the hand. The apparatus comprises an elongate splint member and apparatus for mounting the splint member to the body for pivotal movement about an axis which passes through an end region of the splint member and for locking the splint member into a selected position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
235 words
An adjustable digital splint for a hand, said splint comprising an elongate bone splint, a plate member configured to substantially correspond to, and sized to overlie, the contour of a portion of a user's hand on the palm side thereof; connector structure that cooperates with said bone splint and with said plate member for holding said bone splint and plate member in immobile assembled position relative one to the other, said connector structure comprising a pivot device that couples said bone splint to said plate member at a first position, said pivot device permitting pivotal movement of said bone splint relative to said plate member about an axis to select the final use position of said bone splint, a splint fastener that couples said bone splint to said plate member at a second position, said splint fastener holding said bone splint in the selected pivot position relative to said axis, the first and second connection positions of said bone splint and said plate member being spaced one from the other, the first and second spaced positions of said bone splint and plate member connections maintaining said bone splint and plate member in the immobile non-pivoting assembled position one with the other through use of said splint fastener even if the pivot device connection is a loose connection, and means for mounting said plate member over the hand of a user on the palm side thereof.
Claim 2
Dependent Claim
235 words
An adjustable digital splint for a hand, said splint comprising an elongate bone splint, a plate member configured to substantially correspond to, and sized to overlie, the contour of a portion of a user's hand on the palm side thereof; connector structure that cooperates with said bone splint and with said plate member for holding said bone splint and plate member in immobile assembled position relative one to the other, said connector structure comprising a pivot device that couples said bone splint to said plate member at a first position, said pivot device permitting pivotal movement of said bone splint relative to said plate member about an axis to select the final use position of said bone splint, a splint fastener that couples said bone splint to said plate member at a second position, said splint fastener holding said bone splint in the selected pivot position relative to said axis, the first and second connection positions of said bone splint and said plate member being spaced one from the other, the first and second spaced positions of said bone splint and plate member connections maintaining said bone splint and plate member in the immobile non-pivoting assembled position one with the other through use of said splint fastener even if the pivot device connection is a loose connection, and means for mounting said plate member over the hand of a user on the palm side thereof.
Claim 3
Dependent Claim
32 words
The combination of claim 1 wherein said plate member is configured to substantially correspond to, and sized to overlie, the contour of a user3 s hand between the wrist and palm thereof.
Claim 4
Dependent Claim
33 words
The combination of claim 1 wherein said pivot device permits pivotal movement of said bone splint relative to said plate member about an axis located substantially adjacent the heel of a user's hand.
Claim 5
Dependent Claim
96 words
The combination of claim 1 wherein sad plate member mounting means comprise a sleeve defined at least in part by an elastic fabric material, said sleeve including a pouch fixed to said sleeve on the palm side thereof, said plate member being received in said pouch for connecting said plate member to said sleeve, and said sleeve being sized to cover both at least a portion of a user's hand and wrist when said splint is installed on the user's hand for enhancing stability of said bone splint and plate member assembly on the user's hand.
Claim 6
Dependent Claim
42 words
The combination of claim 4, said plate members and said connector structure being substantially completely enclosed within said pouch, said bone splint thereby being connected to said plate member inside of said pouch and extending outwardly through an opening in said pouch.
Claim 7
Dependent Claim
62 words
The combination of claim 4, said sleeve comprising a gauntlet having opposite side edges disposed generally parallel to the longitudinal axis of a user's hand and arm when said splint is installed, and gauntlet fasteners connected to said opposed side edges, said gauntlet fasteners being adapted to hold said sleeve tight about a user's hand and wrist when said splint is installed.
Claim 8
Dependent Claim
54 words
The combination of claim 6, said gauntlet fasteners comprising hook and loop fasteners, said hook and loop fasteners being partially carried on each of said opposed side edges, said hook and loop fasteners permitting said sleeve to be tightened or loosened as desired depending on the swelling or lack thereof of the user's hand.
Claim 9
Dependent Claim
36 words
The combination of claim 1, said connector structure being adapted to hold a single bond splint in any one of four positions, each position serving the digital bones of different one of a hand's four fingers.
Claim 10
Dependent Claim
72 words
The combination of claim 1, said splint fastener comprising a plurality of locking openings formed through said plate member and a locking opening formed through said bone splint, said plate member locking openings being located such that said splint locking opening is selectively alignable with each of said plate member locking openings to position said bone splint in anatomical alignment with a selected finger upon pivoting said bone splint about said axis.
Claim 11
Dependent Claim
25 words
The combination of claim 9, wherein said plurality of locking openings include four locking openings in said palm plate that define a generally arcuate locus.
Claim 12
Dependent Claim
28 words
The combination of claim 9, said connector structure being adapted to hold said single bone splint in a position that serves the digital bones of a hand's thumb.
Claim 13
Dependent Claim
102 words
The combination of claim 10 wherein the spacing between a selected two of said plate member locking openings is substantially equal to the spacing between each plate member locking opening and said first position so that said selected two plate member locking openings and said first position form an equilateral triangle and wherein said selected two plate member locking openings are located such that said bone splint is coupleable to said selected locking openings in immobile assembled position relative one to the other and so that said splint member extends in anatomical alignment with the thumb of the hand of the user.
