Abstract
Method for the production of a hearing aid support matched to the auditory meatus of a user. With this method a setting material is introduced into the auditory meatus of the user. After said material has set, a negative is made and after machining this negative, if necessary, and placing the hearing aid, or a substitute for the hearing aid, therein, the support is produced. According to the invention an aid that corresponds to the shape of the universal hearing aid is introduced into the auditory meatus before setting material is introduced into the auditory meatus.
Claims13
Method for the production of a hearing aid support matched to the auditory meatus of a user, comprising introducing a setting material into the auditory meatus, which material is deformable in the set state, removing said part of set material from the auditory meatus, producing a negative of said part of set material by applying further setting material around it and setting said further material and removing said part of set material from said negative, fitting the universal hearing aid or a part of corresponding shape in the negative and introducing setting material into the gap between said hearing aid or part of corresponding shape and the remainder of the space in the negative, followed by removal from the negative of the support produced in this way, characterised in that before the setting material is introduced into the auditory meatus, an auxiliary part having a shape that corresponds to said universal hearing aid is placed in said auditory meatus.
Method according to one of the preceding claims, wherein a protection for the user's eardrum is introduced before said auxiliary part is introduced.
Method according to one of the preceding claims, wherein a sleeve component having an interior shape for accommodating said universal hearing aid is introduced into said negative.
Method according to one of the preceding claims, wherein there is a distance of at most 5 mm between the user's eardrum and said auxiliary part when introducing said setting material.
Method according to one of the preceding claims, wherein said auxiliary part is made of the same material as said setting material.
auxiliary part (1) to be fitted in the auditory meatus of a user for the production of a support for a hearing aid, comprising an elongated component of plastic material provided with a passageway (2) extending through said auxiliary part in the longitudinal direction, which auxiliary part is bent in the longitudinal direction thereof with a bend angle (α) of at least 15°.
