AI Technical Summary
Technical Problem
Existing earmolds for insertion into the ear canal often cause discomfort and difficulty in removal due to rigid structures that exert pressure and friction, especially during sleep or when wearing protective headgear.
Method used
An earmold design featuring a flexible tab or flap that bends inward towards the opening, allowing easy removal and minimizing pressure sensations by being imperceptible to the user, made from materials like silicone or polyurethane, and manufactured through processes such as PNP or casting.
Benefits of technology
Enhances wearing comfort and simplifies removal by reducing friction and pressure, enabling comfortable use in various positions and environments, including sleep and noisy workplaces.

Abstract
Otoplasty (2) for insertion into an ear canal (1.1) with - at least a first section (2.1) which can be arranged in an outer area of the ear canal (1.1) and has an opening (2.1.1) with a cavity (2.1.2) extending along the ear canal (1.1), - at least a second section (2.2) which can be inserted into an inner area of the ear canal (1.1) and - at least one tab (2.3) projecting outwards in the area of the opening (2.1.1) of the first section (2.1), wherein - the tab (2.3) is flexible and extends substantially distally from the first section (2.1) at an angle (α) towards the opening (2.1.1), - a distal surface (2.1.3) of the first section (2.1) around the opening (2.1.1) lies substantially in one plane, - wherein the angle (α) of the tab (2.3) relative to the plane is 30° to 60°.
