SYSTEM TO CONTROL THE MOVEMENT OF AN ARTIFICIAL KNEE JOINT OF AN ABOVE KNEE PROSTHESIS.

摘要

THIS INVENTION REFERS TO A PROTEST OF THE UPPER PART OF THE KNEE THAT USES A HYDRAULIC SHOCK ABSORBER TO PASSIVE REGULATE THE ANGULAR SPEED OR ROTATION OF THE ARTIFICIAL KNEE JOINT. A PROGRAMMED MICROPROCESSOR RECOGNIZES THE PATTERNS ON THE COMMON WALK FROM THE INFORMATION RECEIVED FROM THE DETECTORS OF THE ANGLE AND TRACTION OF THE KNEE IN THE PROSTHESIS. THE MICROPROCESSOR REACTS TO SEVERAL TRANSITION POINTS ON THE START BY ACTIVATING A MOTOR THAT IN ADJUSTMENTS A VALVE IN THE SHOCK ABSORBER. THE VALVE IS ABLE TO VARIABLY AND INDEPENDENTLY DAMPER THE MOVEMENT OF THE KNEE JOINT AT EACH FLEXION AND EXTENSION AT THE SAME TIME. THE MARCH IS IMPROVED DUE TO THE BEST CONTROL THAT CAN BE TAKEN OF THE ACTION OF THE KNEE. IN ADDITION, DIFFERENT CUSTOMS MAY BE PRACTICED SUCH AS DESCENDING STAIRS OR SITTING.
