A method for forming a part inserted in the auditory canal of a hearing impaired person, said part being either an otoplastic or a carrier part of the hearing aid insertable into the auditory canal or an ear adaptor member for a hearing aid to be worn behind-the-ear, characterized by providing an expandable elastic member, coating said elastic member with a hardenable material, inserting the coated member into an ear of the person who is hearing impaired, allowing the hardenable material to harden to retain the outside contour of the part. The elastic expandable member may be either a porous member which is partially saturated on the outer surfaces or may be a smooth member which is coated with the hardenable material. If desired, a physiologically compatible coating may be applied onto the hardened surface layer subsequent to the hardening process. |

DETAILED DESCRIPTION An object of the present invention is to provide a method for the manufacture of either an otoplastic or of a customized ear adaptor member utilizing expanded plastics that can be implemented without the manufacturing of an impression of the ear canal and of a negative of the impression and which method does not exhibit the disadvantages set forth hereinbefore.
It is also an object of the present invention to provide an ear adaptor member, as well as an otoplastic, that are manufactured of expanded plastic as a durable adaptor part with little cost.
The objects of the invention are achieved with an improvement in a method for the optimum manufacture of a member for insertion into the ear canal including customized ear adaptor members and otoplastics, said method utilizing a carrier part and at least a partially expandable elastic shaped part that is placed in the carrier part.
The improvements comprise coating a portion of the elastic expandable part with a hardenable material, inserting the part with the coating into the ear of the hearing impaired person and allowing the hardenable material to harden.
By utilizing a partially porous expandable plastic member, it can be moistened with the hardened material, which will harden to retain the shape of the outside contour after removal of the part or otoplastic from the ear.
If an ear adaptor member is being formed, this member is of a partially porous expanded plastic that is moistened with the hardenable material and it will retain the adapted outside contour, even after the ear adaptor member has been removed from the ear.
Otoplastics, as well as ear adaptor members, can be manufactured in an especially beneficial way by moistening a porous, elastic formed part with a hardenable material.
The moisture formed part can be adapted to the auditory canal without complicated mechanisms.
It is simply positioned in the ear until it hardens, which takes approximately 10 minutes.
This saves both the time, as well as cost.
Differently shaped base members, likewise, are not required, since a uniform shaped base member or even the in-the-ear hearing aid itself can be utilized, given otoplastics or when sound lines are being employed given the adaptor member
