Ear canal device retention means

摘要

The invention regards an ear canal device and a retainer strip, whereby the ear canal device has a distal part for extending into the ear canal and facing the tympanic membrane and a proximal part extending towards the ear canal opening, wherein the proximal part of the ear canal device comprises an opening extending transversely through the ear canal device, and where a retaining strip is arranged with a first end thereof arranged to be fastened in the opening and a second end arranged to lie resiliently against the inside of the concha for exerting a retaining force on the ear canal device.

主权项

1. An ear canal device, comprising:
a distal part for extending into an ear canal and facing a tympanic membrane; a proximal part extending towards an opening of the ear canal where the ear canal device is coupled to one end of a wire, where the wire has a connection part at its other end, the proximal part including an opening configured to receive a retainer strip and fasten the retainer strip relative to the proximal part; and the retainer strip inserted into said opening of the proximal part, the retainer strip including a first end configured to be fastened in the opening, and a second end configured to lie resiliently against the inside of a concha to exert a retaining force on the ear canal device, wherein the second end of the retainer strip is slidably inserted from one open end of the opening to another open end of the opening to a position where a widening knob on the first end of the retainer strip is in contact with an edge of the one open end of the opening.
