PUMP FACILITY FOR A HEARING DEVICE AND METHOD OF INFLATING AND DEFLATING AN EARMOLD MEMBER |
摘要 |
A pump facility for an earmold of a hearing device communicates by way of a channel facility with a variable-volume element of the earmold. A medium can flow through the channel facility to the variable-volume element and away from the variable-volume element. A filling mechanism is embodied for pumping the medium through the channel facility to the variable-volume element. In addition a drainage mechanism is embodied for actively pumping and conveys the medium away from the variable-volume element through the channel facility. |
