4. Useful information on the device

Accessories The safe functioning of the device can only be guar- anteed if the accessories recommended by the manu- facturer are used. Important Protecting against leaks When filling the medicine container with medicine, ensure that you do not exceed the maximum mark (8 ml). The recommended filling amount is between 2 and 8 ml. During use, you can tilt the device up to a maximum angle of 45 ° in any direction, without impairing its nebulising function or the success of the treatment. However, spraying only takes place if the substance to be sprayed is in contact with the mesh. If it is not, spraying stops automatically. However, please try to hold the device as upright as possible. Automatic switch-off The device has an automatic switch-off function. To prevent damage to the mesh, the device switches off automatically when the medicine/liquid has been al- most entirely used up. Do not use the device if the medicine container or wa- ter tank is empty. The device switches off automatically if the substance to be sprayed is no longer in contact with the mesh.

Before using the unit for the first time Note

The atomiser and accessories must be cleaned and disinfected before they are used for the first time. For information about this, see “Cleaning and disinfec- tion” on page 16. Assembly Remove the unit from the packaging.

If not already fit- ted, fit the mesh atomiser (3) onto the neck of the container (2), and lock into place by turning it clock

wise until the silver-coloured contact elec

trodes are facing downwards.

Place the container with fitted mesh firmly onto the housing (6) or base of the device, so that you hear it click into place on the left and right.

To open the battery compartment (7) on the under- side of the device, apply light pressure and pull the battery compartment cover in the direction of the ar- rows, then fold the lid up.

Ensure that the poles of the batteries are touching their respective poles in the device (see illustration on the bottom of the casing).

Fold the battery com- partment lid down again and push it back in place, in the opposite direction to the arrows. Note

When changing batteries, ensure that the medicine container is completely empty, otherwise there is a risk of leaks.

When the orange LEDs (4) light up, replace all four batteries, because spraying becomes much less ef

fective when the batteries are weak.

You can operate the device for approx. 180minutes with new alkaline batteries.

This is sufficient for 5 – 9 uses of saline solution (de- pending on the dose and duration of each use). Operating the device with the power pack Only connect the power pack (13) to the mains voltage listed on the type plate.

Open the battery compartment lid to connect the power pack (13).

Insert the power pack connector (8) into the connec- tion socket provided (15), and the power pack (13) fully into a suitable socket. Note

Ensure that there is a socket near to where the unit will stand.

Lay the mains cable in such a way that no one can trip over it.

To disconnect the nebuliser from the mains after use, first switch off the device and then remove the plug from the socket.

The batteries must not be removed from the mains part (13) during operation.

The power pack (13) cannot be used for charging batteries.

For reasons of hygiene, it is imperative that the atomiser and accompa

nying accessories are cleaned and disinfected after every use. If the therapy requires that various different medi

cines be inhaled in succession, ensure that the atomiser is rinsed after every use. For details, see Cleaning and disinfection on page 16.

Remove the cover (1) from the device.

Open the medicine container (2) by opening the clip, and fill the medicine container with an isotonic saline solution or medicine. Do not overfill! The maximum recommended fill amount is 8 ml.

Use medication only on the advice of a physician, and check the appropriate inhalation duration and quantity for your needs.

If the recommended dose of the medicine is less than 2 ml, top up this quantity to at least 4 ml using only isotonic saline solution. Viscous medicines may also require dilution. Always follow the instructions of your doctor.

Close the lid of the medicine container (2) and click the clip in place, and then refit the cover (1).

4. Fitting accessories

When the required accessories (mouthpiece, adu lt mask or child mask) have been attached to the de

vice, attach the device firmly to the assembled medi- cine container (2).

The adult mask and child mask must be fitted using the connecting piece (12) (adapter).

Now place the device to your mouth and close your lips firmly around the mouthpiece. When using either of the masks, place it over the nose and mouth.

The spray mist coming from the device and the illu- minated blue LEDs (4) show that the device is work- ing perfectly.

Breathing technique The right breathing technique is important to ensure that the particles are distributed as widely as pos- sible into the air ways. So that they can enter the air ways and lungs, you must inhale slowly and deeply, hold your breath briefly (5 to 10 seconds) and then exhale quickly.

You should only use nebulisers to treat respiratory disorders if advised to do so by your doctor, who will recommend the medicine, dose and application for inhalation therapy.

Certain medicines are only available on prescription. Note You should hold the device as upright as possible. Tilting it slightly will not, however, affect its function, since the container is leakproof. To ensure that the device functions correctly, make sure that you do not tilt it more than 45 ° in any direction and that the medicine is in contact with the mesh while in use. Important Essential oils, cough medicines, solutions designed for gargling, and drops for application to the skin or for use in steam baths are wholly unsuitable for inhalation using a nebuliser. These substances are often highly viscous and can impair the correct function of the de- vice and hence affect the effectiveness of its applica- tion in the long term. In the case of oversensitivity of the bronchial system, medicines containing essential oils can sometimes cause acute bronchiospasm (a sudden, cramp-like tightening of the bronchi accompanied by breathless- ness). Always ask your doctor or pharmacist for advice!

6. End of inhalation

After treatment, switch off the device using the on/ off button (5).

The LEDs (4) go out.

Once the inhalant has been fully sprayed out, the device switches off automatically. For technical reasons, a small amount may still re- main in the medicine container (2).

If applicable, disconnect the power pack (13) from the mains.

For information about this, see “Cleaning and disinfec- tion” on page 16.

8. Cleaning and disinfection

Warning Observe the following hygiene instructions in order to avoid any health risks.

The nebuliser and accessories are intended for mul- tiple use. Please note that cleaning and hygienic re- conditioning requirements differ according to the dif- ferent areas of application.17 Note

Do not clean the mesh or accessories with brushes or similar, as this may cause irreparable damage, and this will mean that the intended result of the treat- ment is no longer guaranteed.

For additional requirements regarding the necessary hygienic preparations (hand washing, handling of medicines or inhalation solutions) in high-risk groups (e.g. cystic fibrosis patients), contact your doctor. Cleaning The mesh atomiser and container, as well as acces- sories such as mouthpiece, mask, connecting piece, etc. must be cleaned with hot water after each use. Carefully dry all components using a soft cloth. Once all components are fully dry, reassemble the atomiser and place the components in a dry, sealed container or carry out disinfection.

Remove the mouthpiece and any accessories from the atomiser.

Add 6 ml of clean water to the medicine container (2) and switch on the device to first remove any medicine residue from the mesh. (Please spray the entire liquid).

Remove the batteries.

Remove the detachable parts from the device, e.g. mesh atomiser or medicine container and cover. Disassembly To continue with cleaning its individual components, disassemble the atomis- er (2, 3):

Remove the medicine container (2) and mesh atomiser (3) by pressing both brackets inwards and drawing the unit out.

Remove the mesh atomiser (3) from the medicine container (2) by turning it anticlockwise and drawing it out.

The nebuliser is later reassembled in the re

verse order. Important Never hold the complete device under running wa- ter to clean it. When cleaning, ensure that all residues are removed. Never use any substances that may be poisonous when in contact with the skin or mucous membranes, or when swallowed or inhaled. If required, you can clean the device casing with a lightly moistened cloth that has been soaked in mild soapy water.

If there is any residue from medical solutions or con- tamination on the silver-coloured contacts of the de- vice or atomiser, clean with a cotton bud moistened with ethyl alcohol.

Clean the outside of the mesh and outside of the medicine container with a cotton bud dampened with ethyl alcohol. Important

Before you clean the unit, always switch it off, unplug it and let it cool off.

Do not use abrasive detergents and never immerse the unit in water.

Ensure that no water penetrates inside the unit!

Do not put the device or accessories in a dishwasher.

Do not touch the unit with wet hands while it is plugged in; do not allow any water to be sprayed onto the unit. The unit must be operated only when it is completely dry.

Do not spray any liquids into the ventilation slots. Any liquid that penetrates into the unit can damage the electrical parts or other components of the nebuliser and impair the function of the device. Important We recommend carrying out inhalation without inter- ruptions since the inhalant may clog the mesh atomiser during a long pause in treatment, and the effectiveness of the application may be impaired as a result. Disinfection Follow the steps listed below carefully in order to disin- fect your atomiser and the accessories. It is advisable to disinfect the individual components after the last time they are used each day at the latest. You can disinfect the IH 50 and its accessories in two different ways, either with ethyl alcohol or in boiling water. First clean the atomiser and the accessories as de- scribed under “Cleaning”. You can then continue with disinfection.18 Important Ensure that you do not touch the mesh (3), as this may destroy it. Disinfection with ethyl alcohol (70-75%)

Pour 8 ml ethyl alcohol into the medicine container (2). Close the container. Leave the alcohol in the con- tainer for at least 10 minutes.

For better disinfection, shake the unit gently from time to time.

Repeat this process, using water this time.

Place the medicine container (2) in a position that al- lows you to apply a few drops of ethyl alcohol to the mesh (3). Allow the alcohol to work for 10 minutes.

Finally, clean all parts again under running water. Disinfection with boiling water

The atomiser should be disassembled as described and, together with the mouthpiece, placed in boiling hot water for 15 minutes. Avoid the parts coming into contact with the hot base of the pot.

You can also disinfect the atomiser and the mouth- piece with a standard vaporiser. Observe the manu- facturer’s instructions for use for the vaporizer when doing this.

The atomiser must not be placed in the microwave. Note The face masks and air hose must not be placed in hot water!

We recommend disinfecting the masks using a retail disinfectant. Drying

Carefully dry all components using a soft cloth.

Shake the mesh atomiser (3) lightly backwards and forwards (5 to 10 times), so that the water inside the mesh is removed from the small holes.

Place the individual components on a dry, clean and absorbent surface and allow to dry completely (for at least 4 hours). Note Ensure that all parts are thoroughly dried after cleaning, otherwise there is an increased risk of bacterial growth. Once all components are fully dry, reassemble the nebuliser and place the components in a dry, sealed container. Ensure that the mesh atomiser (3) has dried completely by shaking it. Otherwise, nebulisation may not function properly after reassembling the device. If this is the case, disassemble the mesh atomiser (3) again and shake it so that the water can escape. Once it has been reassembled, the nebuliser should function properly again as usual. Material resistance

When choosing a cleaning or disinfecting agent, note the following: Only use mild cleaning or disinfectant agents in the quantities recommended by the manu- facturer.

As with all plastic components, frequent use and cleaning of the atomiser and the accessories can lead to a certain amount of wear. Over time, this can alter the aerosol properties and may eventually af- fect the efficiency of therapy. We therefore recom- mend that you replace the atomiser and accessories at least once a year. Storage

Do not store the nebuliser in a damp atmosphere (e.g. in the bathroom) or transport it together with damp objects.

. Insufficient medicine in the atomiser.

. The atomiser is not held in an up- right position.

. The medicine used is unsuitable for spraying (e.g. too thick, viscos- ity must be less than 3). The medicine solution should be specified by the doctor. Output is too low.

. The batteries are flat. Replace the batteries or connect the power supply unit and try again.

. There are air bubbles inside the medicine container which are pre- venting the medicine from coming into continuous contact with the mesh. Please check and remove any air bubbles.

. Particles on the mesh are imped- ing output. To remove the par- ticles, fill the nebuliser with 2 to 3 drops of vinegar and 3 to 6 ml of water, then nebulise this solu- tion completely. Do not inhale this spray and ensure that you clean and disinfect the medicine con- tainer afterwards (see page 16). If the output does not improve, re- place the mesh.

4. The mesh is worn out.19

cines are suit- able for inhala- tion? Only the doctor can advise you which medicine to use to treat your condi- tion. Consult your doctor. With the IH 50, you can atomise med- icines with a viscosity lower than 3. Some inhala- tion solution remains in the nebuliser. This is normal and occurs for techni- cal reasons. Stop inhaling as soon as you can hear a marked difference in the sound made by the atomiser, or when the device switches off auto- matically due to insufficient inhalant. What should be taken into ac- count when us- ing the device with infants and children?

1. In babies, the mask should cover

the mouth and nose to guarantee effective inhalation.

2. In children, the mask should also

cover the mouth and nose. Nebu- lisation next to a sleeping person is not suitable because insufficient medicine reaches the lungs. Note: Children should only use the device with help and under supervi- sion of an adult. Never leave a child alone with the nebuliser. Inhalation with the mask takes longer. This is for technical reasons. Less medicine is inhaled per breath through the mask holes than us

ing the mouthpiece. The aerosol is mixed with ambient air through the holes in the mask. Does each user need their own accessories? This is absolutely necessary for hy

densing The serial number is located on the device or in the battery compartment. Subject to technical modifications. Wearing parts are not covered by the guarantee. All measurements were obtained with a sodium chlo

ride solution using a laser diffraction method. This diagram may not be applicable for suspensions or highly viscous medicines. More information can be ob- tained from the relevant medicine manufacturer.
