HEARING INSTRUMENT CHARGER DEVICE AND SYSTEM, AND A METHOD OF MANUFACTURING A HOLDER THEREFOR

A method of manufacturing a holder for holding an individually shaped, chargeable hearing instrument in a hearing instrument charger device (30) configured for charging the hearing instrument (1A, 1B), and comprising a first charger coil (22, 24), the method comprising the steps of determining a shape of at least a portion of an ear canal of a user from an ear canal impression (8); designing digitally on a computer, based on the determined shape of the portion of the ear canal, a virtual representation of a hearing instrument shell (1A', 1B') of the hearing instrument (1A, 1B), and planning a position in the hearing instrument (1A, 1B) for a second charger coil (4);shaping a holder (40), based on the virtual representation of the hearing instrument shell (1A', 1B'), such that the holder (40), when located in a hearing instrument charge device (30), supports the shape of the hearing instrument (1A, 1B) in a predetermined position, and such that the first charger coil (22, 24) is adjacent to the second charger coil (4). The holder may preferably be manufactured by vacuum forming a biocompatible, thermoplastic sheet into the desired shape.
