PROSTHETIC LINER AND PROSTHETIC SHAFT SYSTEM COMPRISING PROSTHETIC LINER AND PROSTHETIC SHAFT Russian patent published in 2018 - IPC A61F2/78 A61F2/80 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. Prosthetic liner for application on a stump has an elastic base with a proximal opening for insertion the stump into the receiving space and the distal end. At least one pneumatic piston is located on the outside of the prosthetic liner. System of the receiving sleeve of the prosthesis contains the liner of the prosthesis for application on the stump and the receiving sleeve of the prosthesis. Prosthetic liner for application on the stump has an elastic base with a proximal opening for insertion of the stump into the receiving space and a distal end. Receiving sleeve of the prosthesis with the prosthetic liner forms an intermediate space. At least one pneumatic piston is located on the outside of the prosthetic liner. Receiving sleeve of the prosthesis has a cylindrical region responsive to the pneumatic piston, which is configured to receive an air piston and in which, in the assembled state of the liner of the prosthesis with the receiving sleeve of the prosthesis, a closed volume is formed, associated with at least one locking element preventing backflow of air into the interstitial space.

EFFECT: inventions provide a reliable fixing of the prosthesis on the liner with passive vacuum receiving sleeves, and for the user a sense of stability and increased wearing comfort.
