发明名称 CUSTOM EARPIECE
摘要 A system for making custom earpieces is disclosed. The system can include a two-component dispensing container such as a two-component syringe or a two-component squeeze bulb. The two components stored in the two-component dispensing container are kept separate until they are dispensed. The two components can be dispensed into a balloon disposed within the ear canal of a user. The two components can define an earpiece after they are dispensed into the balloon. A mixer mixes the two components as they are dispensed. The balloon can be attached to the two-component dispensing container such that two components enter the balloon after the two components are mixed. In this manner, a more comfortable and effective custom earpiece can be made more safely and more conveniently.
