DISPOSABLE SLEEVE ASSEMBLY FOR SOUND CONTROL DEVICE AND CONTAINER THEREFOR |
摘要 |
A simple and inexpensive sleeve assembly (10) that is easy to apply to and remove from the distal end portion of a sound control device and can be adapted to provide circumferential contact with a user's ear canal to control sound delivered to that ear canal at a desired level, to provide a cerumen guard at the end of a sound deliver tube (30) included in the sound control device, or to provide both of those functions. The sleeve (10) assembly comprises a first layer (11) of flexible material having a periphery that can be adapted to make partial or complete contact with or conform to the ear canal of a user into which the sleeve assembly is inserted. |
