FIELD: medicine.
SUBSTANCE: prosthesis socket according to the first version comprises a socket body, into which a stump can be inserted, and a flexible liner, which, when the prosthesis socket is worn, is located between the socket body and the stump. Liner is firmly connected to the socket body in the proximal region of the latter. Liner together with the socket body defines a fluid injection space that is connected or can be connected to a device for generating high or low pressure and which is impermeable to the fluid in such a way that, due to the generation of high or low pressure in the fluid injection space, a shearing force in the proximal or distal direction is applied to the end region of the liner. Prosthesis socket according to the second version comprises a socket body, into which a stump can be inserted, and a flexible liner, which, when the prosthesis socket is worn, is located between the socket body and the stump. Liner has a first portion of the liner wall that is fixed or can be fixed to the socket body, and a second portion of the liner wall between which a fluid injection space is formed that is connected or can be connected to a pressure generating device, by means of which a shearing force can be exerted in the proximal or distal direction to the second portion of the liner wall.
EFFECT: group of inventions makes it easier to wear and remove a prosthesis.
