TRENCHED SEALING RETAINER FOR CANAL HEARING DEVICE

摘要

Examples of retaining seal assemblies for acoustically sealing and retaining a canal hearing device or an earpiece within the ear canal are disclosed. The retaining seal assembly may include one or more flanges and a clip element. The flanges may include elongate trenches along an exterior surface of one or more of the flanges. The elongate trenches may allow the flange to conform to the shape of the ear canal and distribute concentric compressive forces when the seal assembly is inserted in the ear canal. The clip element may be formed of a relatively rigid material and may include one or more locking tabs. The conforming flanges may be concentrically positioned over the clip element. The seal assembly may include a debris barrier to provide protection for a sound outlet of the canal hearing device or the earpiece.

主权项

1. A retaining seal assembly for a canal hearing device, comprising:
a medial flange formed of a compliant material and comprising relatively small medial trenches along an exterior surface of the medial flange, wherein the medial flange is configured to conform to a shape of an ear canal and distribute concentric compressive forces when the retaining seal assembly is inserted in the ear canal; a lateral flange formed of the compliant material and comprising relatively large lateral trenches along an exterior surface of the lateral flange, wherein the lateral flange is configured to conform to the shape of the ear canal and distribute concentric compressive forces when the retaining seal assembly is inserted in the ear canal; and a relatively rigid clip element, wherein at least one of the medial and lateral flanges is concentrically positioned over the clip element,
wherein the lateral trenches and medial trenches are sized and configured to provide acoustic sealing in an audiometric frequency range and low frequency venting when the retaining seal assembly is placed in the ear canal.
