"Tubular body for sound transmission"

The innovation relates to a tubular body according to the preamble of the main claim.

Such a device is known from EP 1 061 772 A2.

The known arrangement consists of a three-part titanium

Sleeve system that is implanted in the soft tissue of the outer tube and a housing with the necessary hearing aid technology in the space between the back surface of the auricle and the skin above the temporal bone. The hearing aid module is plugged onto the auricle-side end of the hearing system.

The titanium sleeve system conducts the sound from behind the ear to the eardrum.

The three-part titanium sleeve system consists of a base body that can be connected to the ear canal end and the auricle end via an internal thread. The ear canal end is called the sound outlet head and the auricle end is called the sound pickup head. The screw connection allows the length to be changed and the entire sleeve to be replaced or removed.

sensor system or part thereof.

The innovation is based on the task of improving the known system.

This problem underlying the innovation is solved by the teaching of the main claim.

Advantageous embodiments and improvements are explained in the subclaims.

In other words, it is proposed that a handling hole is provided in the sound outlet head, namely in the funnel of the sound outlet head, which allows handling and holding of the sound outlet head within the

ear canal.

Furthermore, the outer part - and the sound pickup head - is designed with a polygon, so that here too an easy handling and operation of the outer part for

Example when screwing into the base body.

Furthermore, it is intended that a blind plug can be placed on the sound pickup head instead of the hearing aid module, so that when the hearing aid module is not in use, the base body, the outer piece and the earpiece are protected against contamination and the ingress of liquid is reliably prevented, for example when swimming or showering.

Furthermore, according to the innovation, it is proposed that the hearing aid module is equipped with a hearing aid piece that is screwed to the hearing aid module. This makes it possible for the hearing aid piece to be removed for cleaning purposes.

can be unscrewed from the module, and a sieve can also be inserted to protect the inside of the housing from contamination.

An example of the innovation is shown below using

of the drawings. The drawings show in

Fig. 1 a pipe body with blind plug in section, in

Fig. 2 a view of the sound pickup head and in

Fig. 3 in a modified scale the base body

with outer piece and earpiece as well as the

hearing aid module.

In the drawings, 1 denotes a base body which is equipped with an internal thread and into which an outer piece 2 with a sound pickup head 3 can be screwed. Next

From the other side, an earpiece 4 can be screwed into the base body 1, which has a funnel 7 and forms the actual sound outlet head 5. A handling hole 6 can be seen in the funnel 7 of the sound outlet head 5.

Fig. 2 shows that the sound pickup head 3 is designed as a polygon 8, whereby both the handling hole and the polygon 8 allow good and easy handling when inserting and replacing the partial implant.

will be enough.

The drawing also shows the O-rings that serve to seal the various components against each other.

Fig. 1 also shows a blind plug 9 which can be inserted into the sound pickup head 3 of the outer piece 2 and is used instead of the hearing aid module to close the actual base body or the sound line thus formed and to protect it from contamination before it enters.

Fig. 3 shows the base body 1, the outer piece 2 and the earpiece 4 in connection with a hearing aid module 10. The hearing aid module 10 is connected to the outer piece 2 via a hearing aid 11, whereby according to the innovation the hearing aid 11

is screwed to the hearing aid module 10, i.e.

can be screwed so that cleaning work is easy and on the other hand a sieve can be inserted here, which protects the inside of the housing from contamination.

Claims (4)

1. Tubular body for sound transmission for a partially implanted hearing system with a base body and an earpiece with a funnel-shaped sound outlet head and an outer piece with a sound receiving head, which can be connected to the base body by means of a thread, characterized in that a handling bore ( 6 ) is provided in the funnel ( 7 ) of the sound outlet head ( 5 ). 2. Tubular body according to claim 1, characterized in that the sound recording head ( 3 ) is designed externally as a polygon ( 8 ). 3. Pipe body according to claim 1 or 2, characterized by a blind plug ( 9 ) insertable into the outer piece ( 2 ). 4. Tubular body according to one of the preceding claims, characterized by a hearing piece ( 11 ) which can be screwed to the hearing module ( 10 ) and serves to couple the hearing module ( 10 ) to the outer piece ( 2 ).
