Problems solved by technology
This arrangement does not guarantee actual precise delivery of the hearing aid to the intended area of the ear canal at the optimum insertion depth for optimum hearing aid performance after manipulation of the tool
[0014] Furthermore, in the case of the insertion tool of US 8155361 B2, the deformability of the protruding piston and the structure supporting the protruding piston, as well as the design concept of the cover, base body and chimney according to the "one-size-fits-all" principle do not completely prevent the ear canal from being affected during operation wall risk

Embodiment Construction
[0051] initial reference figure 1 , where a cross-sectional view (section taken according to a coronal plane (i.e., the plane that divides the human body into ventral and dorsal segments)) of the ear canal is shown, the ear canal 50 of an adult extending from the ear canal orifice 51 to the tympanic membrane (or "Eardrum")56. This ear canal 50 includes an outer cartilaginous region 53 and a medial bony region 54 . In this context, "outer" would mean oriented or disposed away from the eardrum 56; while "inner" would mean oriented or disposed toward the eardrum 56, also as figure 1 depicted by the arrows in . The length of the adult ear canal 50 measured in the axial direction from the ear canal opening 51 to the eardrum 56 is approximately 25 mm. Due to the underlying cartilage tissue, the cartilage region 53 is relatively soft and moves in response to jaw or jaw movements that occur during speaking, yawning, eating, and the like. The bony region 54 (which may also be des...

This invention relates to a device (100) for insertion of a deep-in-the-canal hearing aid (200) -alternatively designatable as extended wear hearing aid- into an ear canal (50) of an individual user,at a pre-determined insertion depth (d) thereof. The insertion device (100) comprises a customized support (1) comprising an outer profile (2) conforming to the shapes of at least a portion of a conchal cavity (60) and of an ear canal (50) of said individual user; and a guide channel (3), disposed internal to said outer profile (2), extending between a lateral entry opening (4) thereof, for loading said hearing aid (200); and a medial exit opening (5) thereof, for releasing said hearing aid (200) into said ear canal (50). The insertion device (100) further comprises a drive mechanism (6, 7; 8)-actuatable by the hearing aid individual user himself or by a distinct operator- for moving the hearing aid (200) through the guide channel (3) from the lateral entry opening (4) up to the pre-determined insertion depth (d). The outer profile (2) is individually shaped to replicate the shapes of at least a portion of a conchal cavity (60) and of an ear canal (50) of said individual user and is resistant to deformation. The present invention also relates to a method of manufacturing an insertion device (100) for inserting a hearing aid (200) deep into an ear canal (50) of an individual hearing aid user, at a pre-determined insertion depth (d) thereof.
Description
technical field [0001] The present invention relates to a device for inserting a hearing aid into the ear canal of an individual user at a predetermined insertion depth. More specifically, the present invention relates to devices for inserting deep-canal hearing aids (i.e. hearing aids that are not visible in the ear canal) intended to be worn for extended periods of time in the bony region of the ear canal, preferably completely Stay in the bony area instead of inserting and removing every day. Such hearing aids are also generally designated as extended-wear hearing aids. [0002] With reference to a more specific use case, the present invention relates to a device designed to allow for the self-insertion of an extended-wear hearing aid by the same individual who will be using the hearing aid in the individual's ear canal, and to allow the insertion of an extended-wear hearing aid by another operator (not necessarily an audiologist). expertise, such as a caregiver or signif...
