Abstract

A physiologic device having a fluid filled compartment. This is surrounded by an outer sheath fastened to the foot. The sheath holds the compartment under the instep and directs the hydraulic forces into the ankle and lower leg. Pressure produced by walking on the fluid compartment is used to compress the lower leg. This prevents swelling and it can heal ulcers due to bad veins.

Claims

1. A physiologic device comprising a generally U-shaped reservoir means having a base and a pair of extending essentially upright arms in fluid communication with the base of the reservoir means;

a fluid means partially filling said reservoir means; and

a sheath means adapted to be wrapped around the lower extremity of a person'"'"'s leg comprising upwardly extending side portions adapted to substantially encircle the ankle and lower leg, the side portions comprising a pair of edges having fastening means for releasably fastening the same to one another thereby securing the sheath means to the lower extremity of a person'"'"'s leg;

said sheath means further comprising a lower base portion, between the side portions, adapted to substantially encircle the foot, having opposed aperture means for receiving the reservoir arms and holding the same in the proximity of the side portions of the sheath means;

wherein the reservoir means is releasably connected to the sheath means by the aperture means such that the base of the reservoir means is positioned outside of the sheath means and the arms of the reservoir means are positioned within the sheath means;

thereby providing pressure pulsations, developed at the base of the reservoir means and produced by walking, to be transmitted to the arms of the reservoir means and lower extremity of the leg where a pathological condition may exist.

2. The device of claim 1 wherein at least one of the pair of reservoir arms has an opening in the top thereof for the placement of the fluid means into the reservoir means.

3. The device of claim 2 additionally comprising a tongue means stitched in proximity to one of the pair of edges and adapted to rest against the shin of the user when the edges of the sheath means are folded towards the shin of the user.

4. The device of claim 3 wherein the structure of the sheath means additionally defines an aperture, between the side portions and base portion, adapted to receive therethrough and lodge extended the heel of the user when the device is worn.

5. The device of claim 3 wherein said sheath means additionally comprises a plurality of reinforcement members therein.
