Thus, although the instrumentalities described herein are for the convenience of explanation, shown and described with respect to exemplary embodiments, which generally include, but are not limited to, supporting (hanging) a human hand via fingers in a way that splays the fingers. It will be appreciated that the principles herein may be applied equally in other types of situations involving similar uses of a suspension fixture to hold an appendage like a hand splayed and suspended consistent with the scope and spirit of the present invention.

[0016] Embodiments in the present invention are generally directed to a hand suspension fixture that provides benefit to healing a burn victim's hand. As illustratively depicted in FIG. 1, a hand suspension fixture 104 embodiment is shown suspending a human hand 110 with the fingers 118 and thumb 124 splayed open. More specifically, the hand suspension fixture 104 comprises five retention fixtures 122 each connected to one of five flexible members 128, such as metal wire, nylon cable, fishing line, and the like, at one end. At the other end, each of the five flexible members 128 are attached to essentially five respective human digits 108, 112, 114, 118, 124. Certain embodiments contemplate essentially the distal end of a human digit being along the distal phalange of the digit. Other embodiments contemplate the fingers 118 being supported closer to the palm of the hand 110. As shown, the human hand 110 is hanging from the hand suspension fixture 104 in such a way that the fingers 118 are spaced apart to splay the five fingers 118 apart from one another when hanging from the suspension fixture 104. In this way, a hand 110 that has been wrapped with new skin will heal without being touched by adjacent fingers 118 while in an essentially immobile position.

[0017] In this particular embodiment the hand suspension fixture 104 can be held at a hand suspension fixture support 102 by a boom stand, a flexible line hanging from a fixture or ceiling, or some other way that can position the hand suspension fixture 104 to hang a human hand 110 as shown in FIG. 1. The hand suspension fixture 104, as shown in this embodiment, has an arc shaped support plane 120 that facilitates the rotation of each of the five retention fixtures 122 via pivot locking mechanisms 106. Certain embodiments contemplate the pivot locking mechanism 106 being knurled bolts, nuts, quick releases, and the like that can be tightened in place. As shown in this embodiment, each retention fixture 122 possesses a retention fixture slot 130 that provides the appropriate adjustment to hang each finger 118 in a desired position. Once in the desired position, the retention fixture 122 can be locked in place by tightening the pivot locking mechanism 106. Other embodiments contemplate the pivot mechanisms 106 being free to rotate along the arc shaped support plane 120 whereby the adjustment to splay the fingers 118 in a desired way can be accomplished at the flexible member attachment location 126.

[0018] FIG. 2 depicts a perspective view of an embodiment of a hand suspension fixture 204 consistent with embodiments of the present invention. As shown in this embodiment, the retention fixtures 122 are set in place along the hand suspension fixture 104 by the knurled bolts 204. The knurled bolts 204 can be screwed in by hand and tightened against the arc shaped support plane 120, which provides mating threads to the knurled nuts 204. The retention fixtures 122 can pivot about the knurled bolts 204 or slid away or towards a hand (not shown) to be suspended. The retention fixture 122 positioned for an index finger, or second digit, is depicted partially slid away (see arrow 202) from where a human hand (not shown) is intended to reside. Each retention fixture 122 possesses a hook 226 adapted to receive a looped end 208 of a wire 206, or more generally a line, which is an embodiment of a flexible member 128. The wire 206 possesses a finger retention clamp 214 that is able to pivot around pivot point 212 to close pointed ends 215 around the sides of the distal phalange (last digit) of each finger in the direction of the arrows 210. Other embodiments contemplate a pair of needled ends penetrating the sides of the distal phalange of each finger, a tap or screw that penetrates into the bone from the sides of the distal phalange of each finger, or some other mechanism strong enough to hang a human hand by the fingertips from the hand suspension fixture 104.

[0019] FIG. 3 depicts yet another embodiment of a hand suspension fixture 304 consistent with embodiments of the present invention. As depicted, the retention fixtures 322 are set in place along the hand suspension fixture 304 by locking mechanisms 306, which certain embodiments contemplate could be a finger tightening bolts, nut, quick release, or other mechanical locking mechanism known to those skilled in the art. Each retention fixture 322 is able to pivot around the locking mechanism 306 as shown by the retention fixture 340. Each retention fixture 322 is further able to slide towards or away from the suspended hand (not shown in this figure) via the retention fixture slot 330 as depicted by the double-arrow 346. Each retention fixture 322 is also able to slide horizontally along the hand suspension fixture 304 via hand suspension fixture slots 342 as shown by the double-arrow 344. Each retention fixture 322 also comprises a flexible member attachment location 326, such as a hook that a wire can loop around, for example.

[0020] FIG. 4 depicts yet another alternative embodiment of a hand suspension fixture 404 consistent with embodiments of the present invention. As shown, the retention fixtures 422 are slidingly engaged along a retention fixture bar 442 by locking mechanisms 406, which in one embodiment could be a sleeve that wraps around at least a part of the retention fixture bar 442 that can be tightened by hand via a knurled nut or bolt. In this embodiment, the retention fixtures 422 are capable of moving along the length of the retention fixture bar 442 as depicted by the double-arrow 444. The retention fixtures 422 are further capable of sliding towards or away from a hanging hand (not shown in this figure) via the retention fixture slot 430 as depicted by the double-arrow 430. Also, the retention fixtures 422 are capable of rotating about the locking mechanism 406, as shown by the retention fixture 440. Each retention fixture 422 comprises a flexible member attachment location 426, such as a hook (226) that a wire can loop around, for example. The hand suspension fixture 404 can be attached to a boom stand, or other support fixture, via element 102, to provide a stable support for the hand suspension fixture 404 to suspend a hand 110 and likely the weight of an arm. The stand can be set on the floor, hung from a ceiling, attached to furniture, such as a bed or table, for example. A hand suspension fixture vertical member 408 can be fixedly attached to the retention fixture bar 442, such as from behind the far 442, so as not to obstruct movement of the retention fixtures 422. Alternative embodiments contemplate a hand suspension fixture member supporting the retention fixture bar 442 at one or more of the retention fixture bar ends 450.
