Ankle-sprain edema-control boot assembly
First Claim
1. A boot assembly applicable to either the left or right ankle and foot for applying compression to control edema from a sprain comprising(a) substantially U-shaped pad means of compressible material comprising two legs defining a channel and a connecting portion disposable on the foot with the malleolus between the legs at the bottom of the channel and with the connecting portion on the top of the foot below the malleolus;
- (b) a pliable fabric boot element disposable over the pad means around the ankle and foot from behind with a sole portion of the boot element underlying the foot and comprisingi. upper and lower flaps on one side and upper and lower flaps on the other side of the front of the boot element,ii. one of the upper flaps being an inner flap disposable against the ankle and the other of the upper flaps being an outer flap adapted to overlap and be secured to the upper inner flap,iii. the lower flap on the same side as the upper outer flap being an inner flap disposable over the connecting portion of the pad means and the other of the lower flaps being an outer flap adapted to overlap and be secured to the lower inner flap in a direction opposite the overlap of the upper outer flap so as to compress the top of the foot and its area below the malleolus with a squeezing action opposed by the boot sole portion underlying the foot; and
(c) releasable securing means on the upper and lower outer flaps for securing them to the respective upper and lower inner flaps.

11. A boot assembly applicable to either the left or right ankle and foot for applying compression to control edema from a sprain comprising
(a) substantially U-shaped pad means of compressible material comprising two legs defining a channel and a connecting portion disposable on the foot with the malleolus between the legs at the bottom of the channel and with the connecting portion on the top of the foot below the malleolus; -
(b) the legs of the pad means being initially nonparallel and closer at their outer ends when the pad means is flat and which assume a substantially parallel position when conformed to a patient'"'"'s foot and ankle; (c) a pliable fabric boot element disposable over the pad means around the ankle and foot from behind with a sole portion of the boot element underlying the foot comprising i. upper and lower flaps on one side and upper and lower flaps on the other side of the front of the boot element, ii. one of the upper flaps being an inner flap disposable against the ankle and the other of the upper flaps being an outer flap adapted to overlap and be secured to the upper inner flap, iii. the lower flap on the same side as the upper outer flap being an inner flap disposable over the connecting portion of the pad means and the other of the lower flaps being an outer flap adapted to overlap and be secured to the lower inner flap in a direction opposite the overlap of the upper outer flap so as to compress the top of the foot and its area below the malleolus with a squeezing action opposed by the boot sole portion underlying the foot; (d) ankle and toe straps disposable respectively around upper and lower portions of the boot element; (e) an intermediate strap disposable about the boot element around the front of and behind the foot; (f) releasable securing means on the inside of the upper and lower outer flaps for securing them to the respective upper and lower inner flaps; and (g) a rigid stirrup comprising two upwardly extenidng legs adapted to be disposed on either side of the patient'"'"'s ankle and a connecting lower portion adapted to be disposed beneath the sole of the patient'"'"'s foot.

12. A boot assembly applicable to either the left or right ankle and foot for applying compression to control edema from either an inversion or an eversion sprain comprising
(a) a pliable fabric boot element disposable around the ankle and foot from behind and comprising i. upper and lower flaps on one side and upper and lower flaps on the other side of the front of the boot element, ii. one of the upper flaps being an inner flap disposable against the ankle and the other of the upper flaps being an outer flap adapted to overlap and be secured to the upper inner flap, iii. the lower flap on the same side as the upper outer flap being an inner flap disposable against the foot and the other of the lower flaps being an outer flap adapted to overlap and be secured to the lower inner flap in a direction opposite the overlap of the upper outer flap, iv. whereby the boot element is reversible and eversible to fit either ankle and foot with a selected right-to-left or left-to-right direction of overlap of the flaps; - and
(b) pad means adapted to be compressed around the malleolus within the boot element comprising a substantially U-shaped element which includes two legs; and (c) removable attachment means for holding the pad means to the inside of the boot element and wherein the removable attachment means are hook-and-pile patches attachable to the respective legs.
