ORTHOPAEDIC APPARATUS FOR RELIEVING LOWER EXTREMITIES OF HUMANS Russian patent published in 2015 - IPC A61F2/68 

FIELD: medicine.

SUBSTANCE: apparatus contains upper, medium and lower parts; the upper part consists of a radius guide with the front rest, to which a saddle and through a bridge a hip hinge, connected to an electric motor, are fixed. The medium part contains an internal post, which is connected movably with the radius guide at the top, and by its internal part with a knee hinge at the bottom. An external post of the medium part is connected with the hip hinge at the top, with the hip and knee hinges beings connected with each other in a mobile way by a motion transmission mechanism. The lower part consist of a U-shaped post, equipped with a V-shaped collar for traction, with the U-shaped post being connected with the medium part by the knee hinge, with a placed on the U-shaped post platform, on which contact switches of an electric motor control system, containing sensors of the external post deviation from the vertical position, and connected with the electric motor, are placed. The apparatus also contains: electromagnetic coupling, placed on the output shaft of the electric motor and connecting the electric motor with a mechanism for the transmission of the orthopaedic apparatus motion. The electromagnetic coupling is electrically connected with a sensor of the accumulator charge through a pulse-width modulator and an electronic key, a neural network transformer of information of the orthopaedic apparatus is electrically connected with the contact switches, the electric motor and feedback sensors, which the measure angle and moment of rotation of the output shaft of the electric motor, as well as the deformation of the motion transmission mechanism.

EFFECT: application of the invention makes it possible to relieve the person's hip and knee joints, enhance the muscular force of the person's lower extremities with simultaneous ensuring the safety of the apparatus exploitation by people and specified accuracy of the angle and moment of the output shaft of the electric motor rotation moment, as well as the deformation of the mechanism of the motion transmission to the knee joint.
