Abstract

A dome for a hearing aid device that is insertable into an auditory canal. The dome has an inner part and a shield which is produced in one piece with the inner part. A wax guard with at least one protective element is arranged inside an opening of the dome. The protective element is flexibly turnable in a direction of insertion of the dome and counter to the direction of insertion of the dome into an auditory canal. A cleaning element, which is movable in the direction of insertion and counter to the direction of insertion of the dome, is cohesively bonded to the shield. A hearing aid device is embodied with a correspondingly configured dome.

Claims

1. A dome for a hearing aid device that is insertable into an auditory canal, the dome comprising:

an inner part;

a shield integrally formed in one piece with said inner part and having an opening formed therein;

a wax guard with at least one protective element disposed inside said opening, said protective element being flexibly turnable in and counter to a direction of insertion of the dome into the auditory canal; and

a cleaning element cohesively bonded to said shield and disposed to be movable in the direction of insertion and counter to the direction of insertion of the dome.

2. The dome according to claim 1, wherein said cleaning element is cohesively bonded to said at least one protective element.

3. The dome according to claim 1, wherein said at least one protective element is curved in the direction of insertion of the dome.

4. The dome according to claim 1, wherein said cleaning element comprises an actuating element, by way of which said cleaning element is movable in the direction of insertion and counter to the direction of insertion of the dome.

5. The dome according to claim 4, wherein said actuating element extends, in the direction of insertion, through the at least one opening formed in said shield.

6. The dome according to claim 4, wherein said at least one protective element is movable in the direction of insertion and counter to the direction of insertion of the dome via said actuating element.

7. The dome according to claim 1, wherein said at least one protective element comprises a foot which, with reference to the direction of insertion, extends in a radial direction into said opening of said shield and is cohesively bonded to said actuating element.

8. The dome according to claim 1, wherein said cleaning element has at least one wing which, with reference to the direction of insertion, extends outward in a radial direction.

9. The dome according to claim 8, wherein said at least one wing of said cleaning element has a peripheral surface that comes to bear on an inner circumferential surface of said opening of said shield during a movement of said actuating element.

10. The dome according to claim 9, wherein said at least one wing has side faces that come to bear on said side faces of said at least one protective element during the movement of said actuating element.

11. The dome according to claim 10, wherein said at least one protective element of said wax guard is one of at least two protective elements spaced apart from each other, and said cleaning element has at least two wings which, during a movement of said actuating element, engage in gaps formed between said spaced-apart protective elements.

12. The dome according to claim 8, wherein said at least one wing of said cleaning element has side faces that come to bear on said side faces of said at least one protective element during a movement of said actuating element.

13. The dome according to claim 8, wherein said at least one protective element of said wax guard is one of at least two protective elements spaced apart from each other, and said cleaning element has at least two wings which, during a movement of said actuating element, engage in gaps formed between said spaced-apart protective elements.

14. A hearing aid device, comprising a dome according to claim 1.
