Powered antithrombotic foot mobility device

Abstract

A foot mobility device includes a body, two pedals rotatable about an axis in opposition to each other and relative to the body, and a motor drive assembly. The feet of a user are placed on the pedals, and the motor drive assembly is powered to move the pedals even while the user is completely passive; i.e., without any active participation by the user. Moreover, the sensation received by the use, rather than being one of typical “exercise”, is massage-like and therapeutic, all while providing the same benefit of increased blood circulation due to contraction and relaxation of the calf muscle. The device may also be used in an active mode, pedaled by the user. Moreover, the foot mobility device may be moved between an open configuration adapted for use of the device and a collapsed configuration having a low profile and adapted for storage and portability.

         10 . A foot mobility device, comprising: 
 a) first and second pedals each rotatable about an axis;    b) a housing; and    c) a motor assembly within said housing, said motor assembly being mechanically couplable to said pedals such that said motor assembly can rotate said pedals about said axis, and said motor assembly being mechanically decouplable from said pedals thereby permitting the pedals to rotate under a force of the feet of the user.    
     
     
         11 . A foot mobility device according to  claim 10 , wherein: 
 said pedals and said housing are relatively movable between an open configuration, in which said pedals are adapted to receive feet of a user and said motor assembly is adapted to move said pedals, and a collapsed configuration in which said pedals and said housing together define a relatively compact size and shape which facilitates portability.    
     
     
         12 . A foot mobility device according to  claim 11 , wherein: 
 in said collapsed configuration, said motor assembly is mechanically decoupled from said pedals.    
     
     
         13 . A foot mobility device according to  claim 11 , wherein: 
 said pedals are movable relative to said housing in a manner other than rotation about said axes such that said pedals and said housing can assume said collapsed configuration.    
     
     
         14 . A foot mobility device according to  claim 11 , wherein:
