The invention discloses a joint
rehabilitation auxiliary therapeutic instrument for old people. The instrument comprises a seat, a
knee joint moving mechanism, an
elbow joint moving mechanism, a controller and a remote controller; the
knee joint moving mechanism comprises a bottom plate, a rail arc plate, a hydraulic driving
assembly, a sliding seat, a lifting driving
assembly, a
crank connectingrod
assembly, pedals, a moving rod and a
knee joint shield; the
elbow joint moving mechanism comprises a fixed arc plate, a rotating arc plate, an
elbow joint shield and a rotating driving assembly; and the controller comprises a master
control circuit board, a
displacement control circuit board and a speed
control circuit board. According to the technical solution, the instrument adopts the sliding fit among the bottom plate, the rail arc plate and the sliding seat, realizes the
reciprocating motion of the pedals through the control of the
crank connecting rod mechanism, simulates the walkingposture, effectively achieves the auxiliary
treatment effect of joint
rehabilitation, controls the controller through the remote controller, can be conveniently adjusted by a user, and has simple operation and high intelligent degree.
