Feedback system for a prosthesis, in particular for an arm prosthesis, and method for generating a stimulus for the wearer of the prosthesis by means of such a feedback system

摘要

A feedback system (10) for a patient's prosthesis comprises a glove (11) which at least partially encloses the prosthesis; at least one sensor (12a, 12b, 12c) which is arranged on the glove (11) and generates a measurement signal (25); at least two complementary feedback units (13, 14, 15), each of which continuously generates at least one feedback stimulus by means of which at least one sensory organ of the patient is stimulated by means of an acoustic, vibrating, optical and / or electrical stimulus; a processing unit (16) which converts the measurement signal (25) into a command, that is to say a feedback signal (26a, 26b), to the feedback units (13, 14, 15); a memory unit (17) which stores the measurement signal (25) and also predetermined limit values (21, 23) which delimit at least three load ranges (20, 22, 24) from one another. The limit values (21, 23) comprise at least a first limit value (21) and a second limit value (23) which is greater than the first limit value (21), the third load range (24) above the second limit value (23) second load range (22) between the first limit value (21) and the second limit value (23) and the first load range (20) is below the first limit value (21). The feedback units (13, 14, 15) are designed in such a way that at least one stimulus is generated from the feedback signal (26a, 26b), which indicates the stress range (20, 22, 24) for the patient.
