AI Technical Summary

Problems solved by technology

[0008] Bushings with molded outer sealing lips are relatively difficult to manufacture
A double-walled sleeve to be rolled around the edge of the prosthesis shaft requires additional material and results in an increase in the circumference of the prosthesis shaft in the proximal region
In addition, no personalization of the prosthetic sleeve is possible

Embodiment Construction

[0056] figure 1 A part of the bushing system 1 with the inner bushing 10 and the outer bushing 20 is shown in a schematic cross-sectional view. The inner sleeve 10 has a smooth-walled inner side 15 and a likewise smooth-walled outer side 16 . The inner bushing 10 is designed in the form of a sleeve and has a distally closed end region 11 so that it is formed as a tube or sleeve, straight-walled or widened conically towards the insertion opening, with a closed end. Cap 12 bushing body. Arranged on the outer side 16 of the inner bushing 10 is an outer bushing 20 whose inner side 25 lies opposite the outer side 16 of the inner bushing. The outer side 26 of the outer sleeve 20 is smooth. The shape and contour of the inner side 25 of the outer bushing 20 substantially correspond to the shape and contour of the outer side 16 of the inner bushing, the inner contour of the outer bushing 20 can have a smaller diameter than the outer circumference of the inner bushing 10 if necessary...

Abstract

The invention relates to a bushing system (1) for resting on a limb or a limb stump, comprising an inner bushing (10) and an outer bushing (20), said inner bushing having a The inner side (15) of the limb stump and the outer side (16) facing away from the limb or the limb stump, the outer bushing has an inner side (25) facing the inner bushing (10) and facing away from the inner side The outer side (26) of the bushing (10) is also configured to bear against the inner bushing (10), wherein, separately from the inner bushing (10) and the outer bushing (20) A sealing element (30) configured to be arranged between the outer side (16) of the inner bushing (10) and the inner side (25) of the outer bushing (20).

Description

technical field [0001] The invention relates to a bushing system for resting on a limb or a limb stump, having an inner bushing and an outer bushing, the inner bushing having an inner side facing the limb or limb stump and an inner side facing away from the limb or limb stump. The outer bushing has an inner side facing the inner bushing and an outer side facing away from the inner bushing and is configured for abutting against the inner bushing. The invention also relates to a method for applying such a lining system. Such a bushing system is provided in particular for a prosthetic bushing system in order to apply a prosthetic component, in particular a prosthesis cartridge, to a limb stump. In principle, it is also possible to fix the orthosis on the limb by means of the bushing system. Here too, there is a need for increased individualization in simple production. Background technique [0002] A prosthetic should replace the function and (where necessary) the shape of a...
