1. A prosthetic socket adapted to receive a residual limb wearing a prosthetic liner as an interface between the prosthetic socket and the residual limb, the prosthetic socket comprising:
a rigid, structural, and load-bearing socket body in a form of a closed-ended cup defining an open-ended proximal end area and a closed-end distal end area, the socket body forming an inner volume adapted to receive a residual limb, the socket body defining a wall thickness from an inner wall surface bordering the inner volume to an outer wall surface, the socket body forming an opening extending through the wall thickness;
a vent element communicating the inner wall surface to the outer wall surface and extending therebetween, and only permits a transfer of air from the inner volume to outside of the prosthetic socket through the opening aside from the open-ended proximal end area, the vent element spanning across the wall thickness from the inner wall surface to the outer wall surface;
wherein the opening is located proximally above a seal region extending circumferentially about the inner wall surface of the socket body distally of the vent element, the seal region demarcating whereat a sealed volume is arranged to be formed between the inner wall surface of the prosthetic socket and the prosthetic liner within the inner volume of the socket and defined distally of the vent element;
wherein the vent element includes an exterior part and an interior part securable to one another within the opening and adapted to extend over adjacent portions of the inner and outer wall surfaces, respectively.
