Heel-suspending protective boot
A protective boot adapted to be worn by individuals when lying in a reclining position. The boot has leg and forefoot portions that provide foot and lower leg support for a wearer while suspending the wearer's heel. The boot may include low-friction materials at an exterior surface of its leg and forefoot portions and at a continuous rim separating the exterior surface from an interior surface of the body, in which case the boot also preferably includes a system for adjustably closing an anterior opening in the forefoot portion by drawing lateral regions of the forefoot portion inward and together. The boot may additionally or alternatively include an L-shaped backplate having portions located at the leg and forefoot portions of the body and adapted to inhibit buckling of the boot within the leg and forefoot portions.
1. A protective boot for use by a person lying in a supine position and supporting a lower leg, heel, and foot thereof, the boot comprising:
a body formed of a flexible and compressible foam material, the body having a proximal leg portion, a distal forefoot portion contiguous with and projecting from the leg portion in a transverse direction thereto, a continuous cavity defined by and within the leg and forefoot portions and being complementary in size and shape to support the lower leg of the person while supporting the foot of the person in an upright position, an anterior opening defined in the leg and forefoot portions to permit the foot and lower leg to pass therethrough into the cavity within the leg and forefoot portions, oppositely-disposed lateral regions defined by the leg portion and separated by the anterior opening, oppositely-disposed lateral regions defined by the forefoot portion and separated by the anterior opening, an interior surface defined by the leg and forefoot portions within the cavity, an exterior surface defined by the leg and forefoot portions, and a continuous rim separating the interior and exterior surfaces;
a cushion within the cavity within the lower leg portion for supporting the lower leg of the person and suspending the heel of the person within the cavity;
a first low-friction material defining the exterior surface at the leg and forefoot portions;
a trim being a second low friction fabric at the continuous rim separating the interior and exterior surfaces, the second low-friction fabric trim being a different material than the first low-friction material defining the exterior surface of the body and being sewn onto the body so as to form the continuous rim in its entirety by compressing and narrowing the foam material of the body along the entire perimeter of the anterior opening;
first means for adjustably closing the anterior opening in the leg portion with the lateral regions of the leg portion; and
second means for adjustably closing a portion of the anterior opening in the forefoot portion with the lateral regions of the forefoot portion by drawing the lateral regions of the forefoot portion inward and toward the medial and lateral sides of the foot of the person within the forefoot portion without applying pressure to the dorsum of the foot.
2. The protective boot according to claim 1 , wherein the body is a unitary, one-piece body formed of the flexible and compressible foam material.
3. The protective boot according to claim 1 , wherein the first low-friction material entirely covers the exterior surface of the body.
4. The protective boot according to claim 1 , wherein the first low-friction material is a cover laminated to the exterior surface of the body.
5. The protective boot according to claim 1 , wherein the second low-friction fabric trim entirely covers the continuous rim.
6. The protective boot according to claim 1 , wherein the cushion has a bevel on a distal end thereof.
7. The protective boot according to claim 1 , wherein the cushion has a bevel on a proximal end thereof.
8. The protective boot according to claim 1 , wherein the entirety of the protective boot is formed from materials capable of being heated and sterilized.
9. The protective boot according to claim 1 , wherein the second closing means comprises a strap secured to the exterior surface at the forefoot portion.
10. The protective boot according to claim 1 , further comprising a pad configured for placement within the cavity and between the foot of the person and the forefoot portion of the body.
11. The protective boot according to claim 1 , further comprising an L-shaped backplate located at the leg and forefoot portions of the body and adapted to inhibit buckling of the boot within the leg and forefoot portions.
12. The protective boot according to claim 11 , wherein the first low-friction material entirely covers a portion of the backplate located at the leg portion of the body.
13. The protective boot according to claim 12 , wherein the first low-friction material entirely covers a portion of the backplate located at the forefoot portion of the body.
14. The protective boot according to claim 13 , wherein the first low-friction material does not cover a portion of the backplate located between the leg and forefoot portions of the body.
15. The protective boot according to claim 14 , further comprising a through-hole in the body that is spanned by the portion of the backplate located between the leg and forefoot portions of the body.
16. A protective boot for use by a person lying in a supine position and supporting a lower leg, heel, and foot thereof, the boot comprising:
a unitary, one-piece body formed of a flexible and compressible foam material, the body having a proximal leg portion, a distal forefoot portion contiguous with and projecting from the leg portion in a transverse direction thereto, a continuous cavity defined by and within the leg and forefoot portions and being complementary in size and shape to support the lower leg of the person while supporting the foot of the person in an upright position, an anterior opening defined in the leg and forefoot portions to permit the foot and lower leg to pass therethrough into the cavity within the leg and forefoot portions, oppositely-disposed lateral regions defined by the leg portion and separated by the anterior opening, oppositely-disposed lateral regions defined by the forefoot portion and separated by the anterior opening, an interior surface defined by the leg and forefoot portions within the cavity, an exterior surface defined by the leg and forefoot portions, and a continuous rim separating the interior and exterior surfaces;
an L-shaped backplate having posterior and forefoot portions located at, respectively, the leg and forefoot portions of the body and a heel portion located between the posterior and forefoot portions of the backplate, the backplate being adapted to inhibit buckling of the boot within the leg and forefoot portions, wherein the leg and forefoot portions of the body extend at least partially over a heel recess defined by the heel portion so as to be spaced apart from the heel portion and reduce the likelihood that the heel of a person wearing the boot will contact the backplate within the heel recess;
a low-friction fabric trim being a different material than the exterior surface of the body and being sewn onto the body so as to form and cover the continuous rim in its entirety by compressing and narrowing the foam material of the body along the entire perimeter of the anterior opening;
a separable adjustable cushion within the cavity within the lower leg portion for supporting the lower leg of the person and suspending the heel of the person within the cavity; and
first means for adjustably closing the anterior opening in the leg portion with the lateral regions of the leg portion.
17. The protective boot according to claim 16 , further comprising a pad configured for placement within the cavity between the foot of the person and the forefoot portion of the body.
18. The protective boot according to claim 16 , the protective boot further comprising a through-hole in the body that is spanned by the portion of the backplate located between the leg and forefoot portions of the body.
19. The protective boot according to claim 18 , further comprising:
a low-friction cover material laminated to and entirely covering the exterior surface of the body, covering portions of the backplate located at the leg and forefoot portions, and not covering a portion of the backplate located between the leg and forefoot portions of the body; and
second means for adjustably closing a portion of the anterior opening in the forefoot portion with the lateral regions of the forefoot portion by drawing the lateral regions of the forefoot portion inward and toward the medial and lateral sides of the foot of the person within the forefoot portion without applying pressure to the dorsum of the foot.
20. The protective boot according to claim 19 , wherein the first and second closing means comprise straps secured to the exterior surface at the leg and forefoot portions of the body.
