Abstract

A protective boot for patients with arterial disease. The boot includes a separate fluid-containing cushion which can be attached in a variety of positions on or in the boot to provide support for the patient'"'"'s foot and leg when bed-ridden.

Claims

1. A medical boot, comprising:

a substantially boot-shaped main body portion formed primarily of substantially soft, flexible, compressible, shape-retaining material;

pillow means for cushioning and supporting the limb of a user, comprising;

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

an easily deformable, fluid-containing cushion disposed within the recess; and

attachment means for releasably connecting the pillow means to a selected location on the boot-shaped main body portion.

2. A medical boot as defined in claim 1, in which the boot-shaped main body portion has a heel and a top opening, and the pillow means has a length substantially less than the distance between the heel and the top opening, whereby the main pillow portion may be located in a selected location between the heel and the top opening of the boot on the inner side thereof to accommodate the configuration of the heel of a user and to support the back of a bedridden user'"'"'s leg.

3. A medical boot as defined in claim 1, including a sole of a relatively stiff material mounted in the inside bottom of the boot-shaped main body portion and removable from the main body portion to permit the user to ambulate with the boot.

4. A medical boot as defined in claim 1, in which the side main pillow portion has a generally rectangular configuration, and the pair of side panels are connected along opposite side edges of the main pillow portion by a linear fold line, and each of the side panels has 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.

5. The medical boot of claim 1 in which the releasable attachment means comprises hook-and-loop means attached to the pillow means.

6. The medical boot of claim 2 comprising a plurality of said pillow means.

7. The medical boot of claim 1 in which the outer covering of the pillow means comprises a composite layer of soft, flexible, compressible, shape-retaining foam material bonded to a layer of ultra-smooth, soft, non-allergenic cloth.

8. The medical boot of claim 7 in which the cloth is moleskin.

9. The medical boot of claim 1 in which the recess in the pillow means is centrally located and is defined by longitudinal seams on each side of the main pillow portion and has a predetermined longitudinal dimension, and the side panels extend laterally outward beyond the seams and comprise lobes extending longitudinally beyond the recess.

10. The medical boot of claim 6 in which the side panel means comprise one side panel on each side of the recess, and the lobes are at one longitudinal end of each side panel.

11. The medical boot of claim 7 in which the side panels are substantially symmetrical about the main pillow portion.

12. A medical boot, comprising:

a substantially boot-shaped main body portion formed primarily of substantially soft, flexible, compressible, shape-retaining material;

pillow means for cushioning and supporting the limb of a user, comprising;

an outer covering of substantially soft, flexible, compressible, shape-retaining material defining a main pillow portion with a recess, and a pair of side panels extending from the main pillow portion;

an easily deformable, fluid-containing cushion within the recess;

the main pillow portion having a substantially rectangular configuration including a pair of substantially parallel side edges forming a foldable seam line between each of the side panels and the main pillow portion;

whereby each of the side panels may be folded over in a face-to-face relationship with the main pillow portion to increase the overall height of the pillow means; and

attachment means for releasably connecting the pillow means in a selected location on the main body portion.

13. A medical boot, comprising:

a substantially boot-shaped main body portion formed primarily of substantially soft, flexible, compressible, shape-retaining material and having an inside covering and an outside covering of moleskin;

pillow means for cushioning and supporting the limb of a user, comprising;

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

an easily deformable, fluid-containing cushion disposed within the recess; and

fabric hook means attached to the pillow means and engageable with the moleskin for releasably connecting the pillow means to a selected location on either the inside covering or the outside covering of the boot-shaped main body portion.
