Pulsating compressor apparatus for enhancing blood flow
First Claim
1. Apparatus for compressing a part of a person'"'"'s body, comprising a flexible band, means for mounting said band on the body part and for encircling the body part, a compression pad connected to said band and movable between a released position and a pressing position compressing inwardly toward the body part, a compressor hinge connected to said band and having a pair of leg members with adjacent inner end portions connected by pivot means and opposite outer end portions, said compression pad being supported by said leg members for movement in response to pivoting of said leg members, a power drive unit including a support member and an output member movable between an extended position and a retracted position relative to said support member in response to operation of said unit, an elongated flexible cable extending within a flexible tubular sheath, said cable and sheath have corresponding first end portions each connected to an outer end portion of a leg member of said hinge, and said cable and sheath have corresponding second end portions connected respectively to said output member and said support member to effect movement of said compression pad between said released and pressing positions in response to pivoting of said hinge by movement of said output member between said retracted and extended positions.

Abstract
A non-stretchable flexible band is wrapped around the arch of a foot and has end portions connected by an adjustable fastener. The bottom portion of the band is attached to a compressor hinge and carries a rigid arcuate pad on which is releasably mounted a replaceable resilient pad. The compressor hinge is connected to a flexible cable and a surrounding sheath which are removably coupled to a power drive unit. The power drive unit reciprocates the cable within the sheath and pivots the compressor hinge between a collapsed position and an extended position where the pads are compressed against a localized region on the bottom of the foot. The drive unit includes an electric motor which is momentarily energized and controlled by a timer module to reciprocate a spring bias rack connected to reciprocate the flexible cable.
