发明名称 Retention and extraction device for a hearing aid
摘要 A hearing aid retention and extraction device comprises a retention ring having an outer bonding surface and an inner grasping surface, and an elongate member extending from the retention ring. The retention and extraction device can be incorporated into a hearing device tip and allows both a hearing device and the hearing device tip to be simultaneously removed from an ear canal. When a user pulls on the elongate member, the retention ring cinches around the hearing device and prevents it from becoming separated from the hearing device tip. The cinching action of the retention ring also holds the hearing device in place within the ear canal.
