DEVICE FOR COMPARATIVE TESTING OF CONTROL SYSTEMS OF ACTIVE MULTIFUNCTIONAL SHOULDER PROSTHESES BY DEVELOPER WITH HEALTHY HANDS Russian patent published in 2021 - IPC A61F2/76 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to devices for comparative testing of control systems of active multifunctional shoulder prostheses by a developer with healthy hands. Proposed device comprises detachable receiving sleeve enveloping arm with maximum forearm. Shoulder covering the shoulder gash is formed as a part of the receiving sleeve and is equipped in the front part with a handle with the possibility of gripping the test by the brush. Device comprises fixed shoulder, fixed on test body and movably connected with receiving sleeve of shoulder-forearm. Angle of flexion angle of the shoulder is placed on the receiving sleeve of the shoulder-forearm. On receiving sleeve of forearm-shoulder transducers of angle of arm removal and horizontal movement of forearm are arranged, and the above sensors are connected with fixed shoulder. Proposed device comprises grip hand control sensor arranged on handle. Bracket is fixed in front part of receiving sleeve, on which an active multifunctional simulator of a shoulder prosthesis is fixed, comprising actuators with in-series connected to each other with self-braking drives of shoulder rotation, forearm flexion, forearm rotation and wrist flexion.

EFFECT: possibility of performing comparative tests of control systems of active multifunctional prostheses of a shoulder by a developer with healthy hands in conditions close to real ones.
