Description

Pack of 4 Click Sleeve For Signia, A&M, a
udibene, Audio Service, HearUSA, REXTON, TruHearing RIC and Instant Fit Click CIC/ITC Hearing Instrument.
One click and it fits. The exchangeable Click Sleeves are easily clicked into place. Made from super-soft silicone, they are available in three different sizes that fit in almost every ear canal for a simple, quick and swift fitting.
The ready-made hearing instrument is placed inside the click sleeve using the Signia click connection system as is in use with RIC instruments.
The click sleeves are composed of two functional regions. A fully flexible portion for maximizing canal shape adaptability, retention, and acoustic sealing. A second semi-flexible portion helps with placement in the ear canal. Given that the hearing instrument is smaller than the sleeve, different vents can be realized via holes at the tip.
The vent flow is then guided through the inside of the sleeve. This completely-in-the-canal system is achieved with a non-invasive miniaturized instrument and a set of soft sleeves. By utilizing only ready-made parts, difficulties from impression taking and hard shell manufacturing are avoided.
The mechanical tasks of ear canal coupling to achieve comfort, retention, and a target venting depending on the hearing loss fall on the soft earpiece alone.
(1) To account for the different sizes of ear canals, three click sleeve sizes S, M, L are offered.
(2) To take different amplification needs into account, all three sizes are available in both closed and vented versions.
(3) In the closed version, used for higher amplification needs, a small vent of 0.8mm diameter and 4mm length realizes an   equivalent vent size of 1.6mm diameter and 16mm length.
(4) In the vented types, two short openings are incorporated on both sides, providing an equivalent vent size of 16mm length and   >4mm diameter.
