Abstract
Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along first axis, a second track disposed on the pair of first tracks, and moving along the first axis, and formed along second axis, a hand holder disposed on the second track, and moving along the second track, and on which at least one of hand and arm of a user is held, a stopper for a track disposed on the pair of first tracks for limiting a movement range of the second track, and a stopper for a holder disposed on the second track for limiting a movement range of the second pair of first tracks, wherein the first axis and the second axis are disposed with an inclination.
Core Innovation
The rehabilitation training apparatus includes a pair of first tracks formed parallel to each other along a first axis, and a second track disposed on the pair of first tracks. The second track moves along the first axis and is formed along a second axis, with a hand holder disposed on the second track so that the hand holder moves along the second track. The hand holder is configured to hold at least one of a hand and an arm of a user, including wrist and shoulder joints for rehabilitation training.
The apparatus further includes a pair of third tracks formed parallel to each other along the second axis. A plurality of first light emitting elements are disposed with a first interval on one of the pair of first tracks, and a plurality of first light receiving elements are disposed with the first interval on the other one of the pair of first tracks to receive first light emitted by the plurality of first light emitting elements. In addition, a plurality of second light emitting elements are disposed with a second interval on one of the pair of third tracks, and a plurality of second light receiving elements are disposed with the second interval on the other one of the pair of third tracks to receive second light emitted by the plurality of second light emitting elements.
The pair of first tracks and the pair of third tracks form a rectangular plate shape having an X-Y coordinate plan. Stoppers, including a track stopper and a holder stopper, limit the exercise range by selectively interrupting and releasing movement paths of the tracks and the hand holder. The apparatus also includes a board with an X-Y coordinate plane formed by crossing light paths using light emitters and receivers, and a pointer on the hand holder that indicates hand-holder location by interrupting light, with a communication module transmitting coordinate data and movement path data to an external device for remote monitoring.
Claims Coverage
Independent claim clm-00001 recites a rehabilitation training apparatus having a specific multi-track geometry with an X-Y coordinate plan and light-emitter/light-receiver sensing arranged along the track axes, supporting hand-holder movement for holding a hand or arm. The coverage is driven by inventive features related to track arrangement, optical sensing along orthogonal axes, and configuration of the hand holder on a moving track.
Parallel first tracks with second track along a first and second axis
A pair of first tracks formed parallel to each other along a first axis; a second track disposed on the pair of first tracks, and moving along the first axis, and formed along a second axis; and a hand holder disposed on the second track, and moving along the second track, wherein the hand holder is configured to hold at least one of a hand and an arm of a user.
Orthogonal rectangular X-Y coordinate plan formed by first and third tracks
A pair of third tracks formed parallel to each other along the second axis; and wherein the pair of first tracks and the pair of third tracks form a rectangular plate shape having an X-Y coordinate plan.
Optical sensing using first light emitters/receivers on first tracks
A plurality of first light emitting elements disposed, with a first interval, on one of the pair of first tracks, and configured to emit first light; and a plurality of first light receiving elements disposed, with the first interval, on the other one of the pair of first tracks, and configured to receive the first light emitted by the plurality of first light emitting elements.
Optical sensing using second light emitters/receivers on third tracks
A plurality of second light emitting elements disposed, with a second interval, on one of the pair of third tracks, and configured to emit second light; and a plurality of second light receiving elements disposed, with the second interval, on the other one of the pair of third tracks, and configured to receive the second light emitted by the plurality of second light emitting elements.
The independent claim coverage centers on a rehabilitation training apparatus that combines a rectangular plate X-Y coordinate plan formed by parallel first and third tracks with a second track carrying a hand holder, and optical sensing implemented by first and second light emitting/receiving element sets disposed along the respective track pairs.
