Immobilization brace with overlapping ventilation ports within semi-flexible boot and foam sheet material liner
First Claim
1. In a lower leg, ankle and foot immobilization brace preventing torsion of the lower leg, ankle and foot of a limb of the user while preventing dorsiflexion and plantar flexion of an ankle joint comprising:
- a generally rigid walker sole;
a semi-flexible open front boot fixedly attached to the top of the walker sole;
at least one elongated ventilation port in the boot;
a foam liner within said boot surrounding the lower leg, ankle, foot and dorsum of the user;
closure means spanning the open front boot for applying general and focal compression to said foam liner encased limb of the user over the lower leg, ankle and dorsum thereby minimizing edema induced swelling over the full extent of the boot;
the improvement comprising;
at least one elongated ventilation port within said foam liner in a position for overlapping of said at least one elongated ventilation port in said boot to facilitate cooling air flow directly from the boot exterior onto the skin of the user'"'"'s limb encased by the foam liner and exposed through said at least one elongated ventilation port within said foam liner.

Abstract
A lower leg, ankle and foot immobilization brace utilizing a semi-flexible open front boot fixed to the top of a walker sole with a plurality of spaced ventilation ports in the boot carries a foam liner within the boot sized to surround the lower leg, ankle, foot and dorsum of the user'"'"'s limb. Spaced closures spanning the open front boot apply gentle and focal compression to the foam liner encased limb. Appropriate elongated ventilation ports within the foam liner overlap a plurality of spaced ventilation ports in the boot to facilitate cooling air flow directly from the boot exterior to the skin of the user'"'"'s limb encased by the foam liner.

9. A vented foam liner for use in a lower leg, ankle and foot immobilization brace preventing torsion of the lower leg, ankle and foot of a limb of a user while preventing dorsiflexion and plantar flexion of an ankle joint, said brace comprising:
-
a generally rigid walker sole; a semi-flexible open front boot fixedly attached to the top of the walker sole; at least one elongated ventilation port in the boot; said vented foam liner being positionable within the boot surrounding the lower leg, ankle, foot and dorsum of the user'"'"'s limb, and said semi-flexible boot comprises closure means spanning the open front boot for applying general and focal compression to said foam liner encased limb of the user over the lower leg, ankle and dorsum thereby minimizing edema induced swelling over the full extent of the boot; the improvement wherein said foam liner includes at least one elongated ventilation port within said foam liner in a position generally overlapping said at least one elongated ventilation port in said boot to facilitate cooling air flow directly from the boot exterior to the skin of the user'"'"'s limb encased by the foam liner and open to said at least one elongated ventilation port within said foam liner. - View Dependent Claims (10, 11, 12, 13, 14)
