OPTOMYOGRAPHIC SENSOR OF AN ELECTROMECHANICAL PROSTHESIS AND METHOD FOR SETTING AN ELECTROMECHANICAL PROSTHESIS Russian patent published in 2022 - IPC A61F2/72 A61B5/1455 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely, to an optomyographic sensor of an electromechanical prosthesis and to a method for setting an electromechanical prosthesis. Optomyographic sensor comprises a body. The body has a surface for interaction with the limb of the user. Optical sensors are located on the surface of the body for receiving data on the processes occurring in the subcutaneous structure of the stump of the user's limb. The optomyographic sensor is equipped with a tool for alternating activation of the optical sensors. The body comprises an element for setting the emission intensity of light falling on the receiver of the optical sensor. The setting element is located on the opposite side of the body from the surface for interaction with the limb of the user. Optical sensors are intended for receiving data on any change in the curvature of muscle fibres, or blood content of the muscle tissue, or tendon movement occurring under the skin of the stump of the user's limb. In the implementation of the method, the electromechanical prosthesis is secured on the limb of the user by means of a stump socket. The optomyographic sensor is calibrated. The sensor is therein calibrated through alternate activation optical sensors to receive data on changes in the curvature of muscle fibres, or blood content of the muscle tissue, or tendon movement occurring under the skin of the stump of the user's limb. The optical sensor wherefor the indicator of relative change in the light permeability was the highest is registered.

EFFECT: production of an optomyographic sensor of an electromechanical prosthesis for controlling the prosthesis with the possibility of setting by means of the element for alternate activation of the optical sensors, and simplification of the stage of calibration of the optomyographic sensor of the electromechanical prosthesis.
