  • Patent number: 11818551
    Abstract: In a method for adapting an otoplastic of a hearing aid, a flexible outer shell is provided which is made of a material that can be cured, but has not yet been cured. A housing interior is sealed at the end facing the eardrum and at the opposite end. The housing interior is connected to a pressure and curing facilitator via a pressure inlet opening. The outer shell is introduced into the ear canal of the hearing aid wearer, and an inner pressure with an increased inner pressure value is applied to the housing interior via the pressure and curing facilitator such that the outer shell lies against the ear canal wall. The hardening process of the curable material is then initiated via the pressure and curing facilitator while maintaining the inner pressure value.
