2. Instruction

2.1 Working principle

This product is mainly composed of piezoelectric components. The piezoelectric components convert electrical energy into mechanical energy and generate ultrasonic vibration The shock wave squeezes the liquid in the medicine cup, so that the liquid medicine passes through the micropores on the atomizing sheet to spray the liquid medicine It is sprayed out as mist and used by inhalers.

2.2 Intended for use

Atomize the medicine, for treatment.
The product is used for the conscious patients, applys to all children and adults, can be used in hospital (not applicable in ICU) and for family.

2.3 Features

• Microporous design, the atomized particle size(MMAD) is 2.3±25% um, more effective absorption.
• Piezoelectric components, low noise design, measured volume ≤ 50dB (A).
• Compact and lightweight, easy to carry.
• One-button design, easy to operate.
• Independent components, easy for cleaning, the medication cup is washable.

DISPOSAL
The device (including its removable pads and accessories) must not be disposed of together with municipal waste at the end of its life, but in compliance with European Directive 2002/96/EC. Since it must be handled separately from household waste, either carry it to a separately collected waste disposal centre for electrical and electronic appliances or give it back to the retailer on purchasing a new device with the same purpose. Any infringement will be severely prosecuted. Specifications and designs are based on the latest information available at the time of printing and subject to change without notice.

WARNING:
This product contains a lithium battery, do not put the product into fire or immerse in the liquid

4.4 Operating nebulizer

4.4.1
Press the power button once to start the device, with the green work indicator on.
4.4 2 Nebulizaton rate adjustment
a) Press the power button once, the device works at a faster nebulization rate, with bright green work indicator.
b) During the device working period, if the user presses the power button for a second time, the device works at a lower nebulization rate, and the green work indicator turns dim.
4.4.3 Auto cleaning mode
If the user keeps pressing the power button for 3s, the auto cleaning mode is a activated.
With the green work indicator flashing, the device works for 2 minutes and than automatically shut down.

1. Press

• If there is no medicine or there is very poorly conductive liquid (for example,distilled water) inside the medication cup, medication cup indicator (blue light) will flash, and then device will auto-off.

• After the power is turned on, the nebulizer will undergo a short start-up period (within about 2 seconds) and then spray normally

• During the spray process, there may be a noise caused by high frequency vibration. Please shake the nebulizer gently to reduce the probability of sound.

• Hold the nebulizer smoothly, relax and start breathing.

• Since the characteristics of the liquid medicine are different, when the nebulizer cannot automatically shut down after some of the liquid medicine is exhausted, please press the power button to shut down the appliance immediately to avoid damage to the mesh.

• When the liquid is about to be exhausted, it is recommended to tilt the front side of the nebulizer (on the side of the spray direction) slightly toward patient, which is good for contacting the remaining liquid to the atomized piece for nebulization.

• Do not cover the vents on the mask and mouth piece with your hands or other objects during the atomization process.

• During using this appliance, if any irregularity or discomfort is observed, please stop use it, and seek medical attention immediately.

• During the atomization process of some liquids, a large amount of foam will be concentrated in the vicinity of mesh in the medication cup, which may easily cause the spray to be interrupted. In this case, turn off the nebulizer immediately, shake the nebulizer slightly, and then restart.

1. may, Foam concentrating area

4.5 Power off

4.5.1 Automatically shutoff after 20 minutes continuous operation.
4.5.2 After the liquid medicine is exhausted, the nebulizer will emit a high- frequency sound, and the medication cup indicator (blue light) will flash and nebulizer shut down automatically.
4.5.3 During use, if you need to stop using it, you can press the power button to turn off the device and the work indicator (green light) goes off.
4.5.4 When using an external power adapter, unplug the power cord after turning off the power.

b) Pour in some clean water and close the medication cup completely. Gently shake the cup to dissolve the residue in purified water.
c) Pour off the liquid and refill with some clean water.
d) Press and hold the power button until the work indicator (green light) lights up and the nebulizer starts to spray It will spray for 3 minutes to clean the residual liquid on the mesh and then shutoff automatically . If there is water remains, lust pour off it

• Ensure medicine be cleaned completely after each using, otherwise, it could cause mesh blocked.
• After entering the cleaning mode, if the nebulizer is running out of water and there is no spray, please turn it off immediately.
• If the residual liquid has not been removed, it can be washed with warm water or repeatedly.
• Clean water includes distilled water, pure drinking water, and the like.

5.1.2 Wash

a) Remove the cup and mask or mouthpiece.
b) Rinse the cup, mask or mouthpiece with clean water. Or soak in clean water for 15 minutes.

1. clean water

c) Main unit:clean the surface of main unit of appliance with a piece of wet fine cotton fabrics, and dry it with a dry cotton fabrics.
d) Clean the electrodes on the main unit and the cup assembly to ensure that the cup is securely attached to the main unit and sprayed normally.

e) Wipe the cleaned parts with clean gauze and dry thoroughly.
f) but on the protective cover on medication cup, install it on the main unit, and store in a clean place.

• Do not wipe the nebulizer with volatile corrosive liquids such as benzene, benzine or thinner.
• Before cleaning the parts, please remove the battery. If you use the power adapter or lithium battery, unplug the power adapter from the socket after turning off the power.
• To prevent residual paper dust or cloth from entering the cup and clogging the atomizer, do not use cotton paper or easy-to-hair cloth to wipe the cup assembly.
• Do not clean the components of the product in the dishwasher, and do not dry the product components in the microwave oven.

5.2 Sterilize

Please disinfect the mouthpiece and mask after each use. If the parts are seriously polluted, please replace the parts in time. It is recommended to have the following two disinfection methods:
a) Alcohol disinfection: disinfect the nozzle and mask with 75% medical alcohol.
b) After disinfection, rinse thoroughly with clean water to avoid residual disinfectant.

• Do not disinfect with a sub-chlorinated disinfectant. Such disinfectant may cause damage to components.
• If you use disinfectant, accidentally get into the eyes or stick to the skin. Rinse with clean water as soon as possible or go to a nearby medical facility.

5.3 Storage

After each use and cleaning and disinfection, confirm that the body and the cup are dry and store them in the box. Place the box in a dry and cool place and keep it away from the reach of children.
