Slim tube HE fitting

Thank you for choosing the slim tube HE option, designed

to provide comfortable, non-occluding fittings with added

high frequency emphasis.

Whether you are an experienced fitter of slim tube

systems or new to this type of fitting, this guide will

explain step-by-step how to assemble the parts of the

system and fit the hearing instrument on your client. The

guide will introduce you to the parts of the system, how

to measure for the right tube length, choose the correct

dome size, and how to attach the slim tube HE to the

hearing instrument so you are ready to program in

TrueFit™.

Warning to hearing healthcare professional: Domes should

never be fitted on clients with perforated eardrums, exposed

middle ear cavities, or surgically altered ear canals. In the case of

such a condition, we recommend to use a customized ear mold. In

the unlikely case that any parts remain in the ear canal after the

removal of the hearing instrument, contact a physician immediately.

Slim tube HE sizes

Slim tube HE is available in four different lengths to

meet the needs of your clients. The red or blue numeric

code on the slim tube identifies the ear to which it

belongs (blue = left ear; red = right ear) as well as the

tube length. Refer to the following chart to identify the

various slim tubes that are available:

Choosing the correct slim tube HE length will ensure a

more accurate, comfortable fit. The measurement tool

included in the kit allows for a quick and simple

measurement and has the following features:

Color Code Markings – blue (left

ear) and red (right ear) color code

markings to indicate which of the

client’s ears to measure.

Horizontal Line Markings – measurements must be made

horizontally with the measurement tool touching the skin

in the gap between the head and the top of the pinna.

Four Horizontal Sightlines – (0-1-2-3) – to indicate which

tube length you should use for an accurate fitting.

To measure for an accurate slim tube HE length:

1. Place your head at the

same horizontal level as

the client’s head so you

are looking straight into

the client’s ear that you

wish to fit with the hearing instrument.

2. Hold the measurement tool with the

appropriate blue or red color code

marking (for the left or right ear) with

your thumb placed on the ear diagram.

3. Place the measurement tool on the

top of the ear and in contact with the

skin in the narrow gap between the

head and the pinna. Keep the

horizontal line on the measurement

tool horizontal and level.

4. Choose the sightline (0-1-2-3) on the

measurement tool that is most parallel

with the top of the opening of the ear

canal. In this example, the sightline

marked 1 would be the most accurate choice.

5. Make a note of the sightline chosen and then repeat

steps 1-4 on the opposite ear for a binaural fitting.

Note: It is important to measure the opposite ear for a

binaural fitting since right and left ear sizes can vary

and thus, require different slim tube HE lengths.

Measuring for an accurate slim tube HE length

Choosing the correct domes

Do an otoscopic examination of the client’s ear canal.

Based on the examination, choose an appropriate dome

to fit the ear canal.

Attaching and removing domes

To attach the dome, push the dome onto the slim tube HE

until it touches the plastic ring.

To remove the dome, grasp the dome between the thumb

and forefinger and pull it off the slim tube HE.

To attach the slim tube HE:

1. Unscrew the earhook from the hearing instrument.

2. Hold the slim tube with the dome attached in one hand

and the hearing instrument in the other hand.

3. Gently turn the hearing instrument onto the slim tube

until it is snug.

Note: To prevent damage to the slim tube, it is recommended

that you turn the hearing instrument onto the slim tube and

not vice-versa.

To remove the slim tube HE:

1. Unscrew the slim tube HE from the hearing instrument

gently.

In some cases, you might find that the slim tube HE does

not lie close to the side of the head or follow the shape of

the ear.

First, ensure the selected dome and slim tube HE sizes

are appropriate (see previous pages).

If a different slim tube HE does not fit better, you may

need to modify the curvature (bend) slightly using the

steps outlined below.

1. Remove the slim tube HE from the hearing instrument.

2. Heat the tube carefully with a hairdryer at a low setting

for a few seconds.

3. Do not use excessive heat to avoid damage to the

tube.

4. Bend the tubing into the desired shape and hold until

it has cooled off. Once completely cooled, the tube will

maintain its new shape.

Attaching and removing the

slim tube HE

Modif ing the slim tube HE to

improve fit

Once you have attached the slim tube HE with dome to

the hearing instrument, you are ready to place the

hearing instrument on the client’s ear.

1. Place the hearing instrument over the top of the ear.

2. Hold the slim tube HE where it attaches to the dome

and gently push the dome into the client’s ear canal.

The dome should be placed far enough into the ear so

that the slim tube HE lies flush against the head.

When looking at your client face-to-face, you should

not see the slim tube HE sticking out.

3. Place the retention piece of the slim tube HE into the

concha bowl.

Note: If the retention piece is too long, you may cut the length

slightly. Be careful not to shorten the length too much, as it

could affect retention in the ear.

Positioning the hearing instrument on the ear

The slim tube HE and dome need to be changed every

three months or when they become stiff or brittle. As part

of the fitting, you will need to counsel the client on how

to clean the dome and the inside of the slim tube HE.

Clients should wipe the dome daily with a damp cloth.

They should also clean the slim tube HE periodically, with

the cleaning pin provided, when they begin to notice

debris in and around the tube.

To clean the slim tube HE and dome:

1. Follow the instructions for removing the slim tube HE

from the hearing instrument. See the section

“Attaching and removing the slim tube HE”.

2. Use a damp cloth to clean the outside of the slim tube

HE and the dome.

3. Remove the dome from the slim tube HE.

4. Using the cleaning pin

provided in the kit,

gently insert the

cleaning pin where the

slim tube HE attaches to

the hearing instrument

and push the pin all the

way through the tube.

5. Attach the dome to the slim tube HE and attach the

slim tube HE to the hearing instrument.

Note: The slim tube HE and dome should never be rinsed or

submerged in water as water drops may become lodged in the

tube, block sound or damage the electrical components of the

hearing instrument.
