Abstract

A soft medical boot mounted in a splint. A soft liquid filled cushion is disposed in the ankle portion of the boot and positioned in an adjusted position with respect to a heel opening in the boot.

Claims

1. A medical boot, comprising:

a substantially boot-shaped main body (12) formed primarily of a substantially soft flexible, compressible, shape-retaining material, the boot body having a heel section and a leg-supporting section with a first fastener-receiving opening;

a rigid unitary splint formed separately from said boot body, said splint having a foot-support section, an elongated leg support section, and a heel section, the leg support section having a second fastener-receiving opening;

said splint being installable on the boot body so that the foot-support section of the splint is located within the boot body;

a cushion (16) receivable in the boot body for supporting the limb of a user, comprising;

an outer covering of substantially soft, flexible, compressible, shape-retaining material defining a main cushion portion;

an easily deformable, fluid-containing container disposed within the main cushion portion; and

fastener means for releasably connecting the cushion (16) to the leg support section of the splint and the leg-supporting section of the main boot body (12) at such times as the fastener-receiving opening in the splint is aligned with the fastener-receiving opening in the leg-supporting section of the boot, at least one of said fastener-receiving openings comprising a slot parallel to the length of the leg-support section of the splint, said fastener means being disposed in said first fastener-receiving opening and the second fastener-receiving opening whereby the cushion is fastened an adjusted distance from the heel section of the boot body depending upon the longitudinal position of the fastener means in said slot.

2. A medical boot as defined in claim 1, in which said fastener means comprises:

a first fastener element carried on the cushion, and a second, complementary fastener element disposed outside the splint and the boot body, and engageable with the first fastener element to releasably lock the cushion to the splint and the boot body, at least one of the fastener elements being receivable in first fastener-receiving opening and the second fastener-receiving opening.

3. A medical boot as defined in claim 1, in which the main cushion portion has a generally rectangular configuration, and including a pair of side panels connected along opposite side edges of the main cushion portion by a linear fold line, each of the side panels having a configuration defined by the fold line, a second linear side edge forming an acute angle with and having one end intersecting the fold line, and a generally curved border continuing from the opposite end of the second linear side edge.

4. The medical boot of claim 1, in which the cushion including a pair of side panels extending from the main cushion portion, each side panel being foldable with respect to the main cushion portion.

5. A medical boot, comprising:

a substantially boot-shaped main body (12) formed primarily of a substantially soft flexible, compressible, shape-retaining material, the boot body having a heel section and an elongated leg-supporting section with a fastener-receiving slot (102) parallel to the length of the leg-supporting section, and a heel portion;

a cushion (16) receivable in the boot body for supporting the limb of a user, comprising;

an outer covering of substantially soft, flexible compressible, shape-retaining material defining a main cushion portion, and a pair of side panels extending from the main cushion portion, each side panel being foldable with respect to the main cushion portion;

an easily deformable, fluid-containing container disposed within the main cushion portion; and

fastener means for releasably connecting the cushion to the leg-supporting section of the boot an adjusted distance from the heel portion of the boot;

said fastener means comprising;

a first fastener element carried on the cushion and a second complementary fastener element disposed outside the boot body, and engageable with the first fastener element to releasably lock the cushion to the boot body, at least one of the fastener elements being receivable in the fastener-receiving slot;

whereby the cushion is connected to the leg-supporting section of the boot body an adjusted distance from the heel portion thereof depending upon the longitudinal position of said at least one of the fastener elements in the fastener-receiving slot.

6. A medical boot as defined in claim 5, in which the main cushion portion has a generally rectangular configuration, and the pair of side panels connected along opposite side edges of the main cushion portion by linear fold line, each of the side panels having a configuration defined by the fold line, a second linear side edge forming an acute angle with and having one end intersecting the fold line, and a generally curved border continuing from the opposite end of the second linear side edge.

7. The medical boot of claim 5, in which the material is moleskin.

8. The medical boot of claim 5, in which the side panels are
