Abstract

A soft medical boot having an articulated splint bar for adjusting the angle of the foot of a patient disposed in a supine position.

Claims

1. A medical boot, comprising:

a substantially boot-shaped main body portion formed primarily of a substantially soft, flexible, compressible, shape-retaining material having a foot portion, an ankle portion; and

a heel opening;

splint means for supporting the limb of a user with his foot disposed in the boot-shaped main body portion comprising;

a substantially rigid insole connected to the foot portion of the main body portion of the boot so as to moveable therewith;

the insole being disposed in the foot portion of the boot;

a substantially rigid splint bar, and means for connecting the splint bar to the ankle portion of the boot;

hinge means for connecting the insole to the splint bar such that the insole is moveable to a selected angular position with respect to the splint bar;

the hinge means comprising an elongated hinge member having one end received in the heel opening and connected to the insole;

pin means connecting the opposite end of the hinge member to the splint bar; and

means for locking the hinge means in said selected angular position, comprising the splint bar having a pair of spaced lugs, said hinge member being received between the lugs, the lugs having pairs of aligned openings, the hinge member having a toe swingeable between the pairs of aligned openings, and locking pin means being received in a selected aligned pair of said openings in the lugs to engage the toe of the hinge in a selected angular position.

2. A medical boot comprising:

a substantially boot-shaped main body portion formed primarily of a substantially soft, flexible, compressible, shape-retaining material having a foot portion and an ankle portion;

splint means for supporting the limb of a user with his foot disposed in the boot-shaped main body portion, comprising;

an elongated substantially rigid insole connected to the foot portion of the main body portion so as to be moveable therewith;

an elongated substantially rigid splint bar, and means for connecting the splint bar to the ankle portion of said main body portion;

articulated hinge means for connecting one end of the insole to one end of the splint bar, the articulated hinge means including a hinge pin disposed such that the insole is pivotal about the hinge pin to a first selected angular position with respect to the splint bar; and

means for locking the hinge means in said selected angular position including a locking pin mounted on the hinge means adjacent the hinge pin, in a position depending upon the selected angle of the insole to the splint bar, the locking pin being removable from the hinge means so as to be repositioned according to a second selected angular position of the insole with respect to the splint bar.

3. A medical boot as defined in claim 2, in which the insole is pivotal to a selected angle less than 180°

but greater than 90°

with respect to the splint bar; and

the main body portion is adapted to receive a patient'"'"'s foot between the insole and the splint bar on one side of the splint bar to generally conform to said selected angle, and both the locking means and the hinge means are located on the opposite side of the splint bar or the patient'"'"'s foot, whereby the locking means is not disposed in a lateral position with respect to the patient'"'"'s foot.
