Abstract: The invention relates to an enveloping body for at least partially recording a contour of a limb, wherein the enveloping body has a base body, and at least one sensor that is configured to record measurement data which can be used to determine a distance and/or relative position between two points in or on the base body.

Abstract: A liner system for applying to a limb or a limb stump, with an inner liner comprising an inner side facing the limb or limb stump and an outer side facing away from the limb or limb stump, and an outer liner that comprises an inner side facing the inner liner and an outer side facing away from the inner liner. The outer liner is designed to be applied over the inner liner, with a sealing element which is designed to be separate from the inner liner and the outer liner, for arranging between the outer side of the inner liner and the inner side of the outer liner.

Abstract: A liner for receiving an amputation stump and for placement within a prosthetic vacuum socket (4). Said liner comprising an inner liner (2) and of an outer liner (3) which are fixedly bonded to each other only in the middle third to a distal third of a length of a liner wall. The outer liner (3) is designed to provide a seal with the prosthetic socket (4).

Abstract: A liner for vacuum sockets for receiving amputation stumps and for use in prosthetic sockets, wherein the liner has a double wall made up of an inner liner (2) and of an outer liner (3), permits improved sealing by a vacuum between liner and prosthetic socket (4) by virtue of the fact that the inner liner (2) and the outer liner (3) are fixedly connected to each other in the middle third and/or distal third and that the outer liner (3) is designed to provide a seal with the prosthetic socket (4).
