Protective medical boot with pneumatically adjustable orthotic splint
First Claim
1. A medical boot, comprising:
- a substantially boot-shaped main body formed primarily of a substantially soft, flexible, compressible shape-retaining material having a hollow foot portion and a hollow leg portion;
splint means for supporting the limb of a patient, with the patient'"'"'s foot disposed in the hollow foot portion of said boot-shaped main body;
said splint means comprising a relatively rigid sole (37) positioned in the hollow foot portion of the boot-shaped main body, a relatively rigid leg splint (48) positioned in the hollow leg portion of said boot-shaped body, hinge means for connecting the sole to the leg splint so that the sole can be adjusted angularly to have a multiple number of discrete angulations relative to the leg splint, and means for selectively locking the sole in discrete angular positions of adjustment with respect to said leg splint;
said rigid sole having one surface thereof facing the interior space defined by the hollow foot portion of said boot-shaped main body;
an insole positioned on said one surface of the rigid sole for contact with the bottom of the user'"'"'s foot when the splint means is in use;
an inflatable member sandwiched between said one surface of the rigid sole and said insole; and
manually-controllable means for incrementally adjusting the inflation pressure within said inflatable member, to produce minor adjustments in the position of said insole.

Abstract
A protective medical boot for treating or avoiding decubitus ulcers has an outer leg covering formed with a pair of cover panels having their seams hot-stamped together to provide a soft edge. An orthotic splint has a leg portion that is supported adjacent the back of the patient'"'"'s leg, and a foot portion that supports the sole of the patient'"'"'s foot. A heel device connects the leg portion to the foot portion at a selected angle with respect to the leg portion. A pneumatically-operated bladder is disposed between the foot portion and the patient'"'"'s foot to provide a very fine adjustment of the angle of the patient'"'"'s foot to his leg to assist in preventing or treating contracture of the patient'"'"'s foot.
