Features and benefits

In the MicroAIR U22, aerosol is generated by pushing liquid medication through fine holes in the newly developed metal alloy mesh. This is realised by a titanium vibrator, oscillating at high frequency. This unique technology offers the following features and benefits:

True portable, pocket size

The device will fit in any handbag or briefcase. Running up to 4 hours on just two penlite batteries, your medication is always within reach wherever you go, whatever you do.

Inhalation is possible at various angles

The device enables inhalation at various angles with stable nebulisation. Therefore the device can be used even while in bed or can be used for a baby/child, laying in the arms of the care-taker.

Soundless operation

The soundless operation of the device enables discrete use.

No loud frightening noises, meaning calm treatment even while using it on a sleeping child.

Simple one-button operation

Wide medication compliance

Low medication waste and residue

How to select the nebulisation mode

Continuous nebulisation mode

If you push the ON/OFF (O/ I) button and release within approximately 1 second, the unit nebulises in continuous mode.

If you push the O/ I button again, the unit stops nebulisation.

The green power indicator lights up during nebulisation.

Manual nebulisation mode

If you hold the ON/OFF (O/ I) button

for approx. 2 seconds or more, the unit nebulises in the manual nebulisation mode.

The unit only nebulises while you keep on pressing the O/ I button and stops nebulisation when you remove your finger from the button.

In this mode, nebulisation may be synchronised with your Inhalation/exhalation cycle and medication waste is minimized.

The green power indicator lights up during nebulisation.

	and instructed by your doctor.	Medication
	1. Slightly tilt the unit as illustrated in the figure.
	In this position, the vibrator is immursed in the
	medication and nebulisation will start after power on.
	After the vibrator has been immursed in the medication,
	the unit can be used under any angle.
	!Caution: In some positions (e.g. upright), nebulisation may
	stop after a short while. In that case, briefly tilt the unit again	Vibrator
	in order to re-immerse the vibrator in the medication.

2. Place the mouthpiece in your mouth or place the mask over mouth and nose.

Always be calm and relaxed when you inhale. Breathe in slowly and deeply so that the medication can reach deep in to the bronchial tubes. Hold your breath briefly, then breathe out slowly while removing the mouthpiece from your mouth. Do not breathe too quickly. Pause when you feel like having a rest.

You may synchronise the nebulisation with your inhalation/exhalation cycles by using the unit in ‘manual nebulisation mode’. Refer to page 13.

Note:

If high-viscosity medication is used, nebulisation may be reduced. Air Port

	If excessive medication collects on the mesh, nebulisation may
	stop. In that case, turn off the power and remove the mask adapter.

After inhalation always switch off the nebuliser by pressing the O/ I button. When an AC adapter was used, disconnect the AC from the electrical outlet. 14

How to clean the unit after each inhalation

Note: if the device is not cleaned and disinfected correctly and frequently, micro-organisms may remain in the unit, causing risk of infection.

The following items should be cleaned after each use: Medication container, mesh cap, mask adapter, mouthpiece and mask.

1. Remove the mask adapter from the main unit.

2. Remove the medication container from the main unit:

3.Remove the mesh cap from the medication container, discard the medication and open the medication container cap. It is recommended to nebulize clean water to remove medication left in the mesh holes after discarding the medication.

4. Remove the mesh cover from the mesh cap.

!Caution: Do not touch the mesh.

15

How to clean the unit after each inhalation

5. Wash the parts (not the main unit!) in a warm soapy solution. Rinse the parts in warm tap water to remove the soap residue.

Some types of medications can easily remain on the mesh, therefore pay close attention during washing.

Do not touch the mesh with a cotton swab, or with a pin.

6. Shake off excessive water from the parts and let them air dry on a clean, lint free (paper) towel.

7.Clean the main unit and it’s electrodes by wiping it off with a (moistened) gauze. Use a dry gauze to wipe the main unit dry.

Do not use volatile agents, such as benzene or thinner.

8.Assemble the unit, refer to page 10.

9.Store the unit in a dry, clean place.

16

How to disinfect the unit each day

Note: if the device is not cleaned and disinfected correctly and as frequently as indicated, microorganisms may remain in the unit, causing risk of infection.

The medication container, mesh cap, mouthpiece, mask and mask adapter should be disinfected

•before using the unit for the first time,

•after the unit has not been used for a long period of time, or

•daily during normal use.

Before disinfection, always first clean the parts as described in the section “How to clean the unit after each use” on the previous page.

Disinfection of the individual parts can be done, using one of the following methods:

1.Disinfection by boiling.

Note: Main unit, medication container and flexible mask can NOT be boiled. For these parts, use other methods, as described below.

Mesh-cap, mouthpiece and mask-adapter can be disinfected by boiling in distilled water. After 10 to 30 minutes of boiling, shake off excessive water from the parts and let them air dry on a clean, lint free (paper) towel.

2.Disinfection by using alcohol.

All parts can be disinfected by using alcohol.

Note: Alcohol is highly flammable; do not use alcohol in close vicinity of open fire; do not smoke. Soak the parts (NOT the main unit) in 70% ethyl alcohol for approx. 1 minute. Shake off exces sive alcohol from the parts and let them air dry on a clean, lint free (paper) towel.

Alternatively, disinfect all parts by wiping them off with a lint-free cloth, soaked in alcohol.

3.Disinfection by commercially available disinfectant. Note: Do NOT soak the main unit in any disinfectant.

Do not use disinfectant containing Sodium (Natrium) Hypochlorite; this may affect the metal parts. For disinfection of the parts, refer to the instructions as supplied by the manufacturer of the disinfectant. After disinfection, thoroughly rinse the parts with warm tap water. Shake off excessive water from the parts and let them air dry on a clean, lint free (paper) towel.

17

How to replace the mesh cap

The mesh cap is a consumeable part.

Omron recommends to exchange the mesh cap after approximately 1 year.

In case the unit nebulises poorly even after boiling in water (refer to “Disinfection by boiling”), replace the mesh cap.

Remove the mesh cap and install a new one as described on page 10 (section “How to assemble the unit and fill the medication container”).
