Abstract
A portable apparatus for imparting continuous passive motion to a human joint. A support is provided for harnessing to parts of the body at one side of the joint and conveyor means movable relative to the support is provided for connection to a part at the other side of the joint, so that the latter forms a link which is flexed as the conveyor means moves back and forth relative to the support. Drive means insures that a substantially continuous slow rhythmic reciprocating movement is applied to the joint.
Claims12
An actuator for imparting back and forth motion in a slow rhythmic cycle, comprising,
- a support housing having a longitudinal slot defining a guide track,
- a traveller operatively mounted to said support housing for back and forth motion relative to said housing,
- a tubular housing mounted in said support housing, said tubular housing having a longitudinally extending slot offset relative to said guide track, and
- a drive member mounted inside said tubular housing adapted to drive said traveller with said back and forth motion, said traveller including a travel element mounted inside said support housing operatively connected through the longitudinally extending slot in said tubular housing to said drive member, said travel element being connected to a travel member mounted for travel along said guide track.
