GENERAL
2.1 Function and application
The nebulizer can atomize medication into a mist of microscopic droplets, which can be easily inhaled into respiratory system
along with breathing, achieving therapeutic effect for respiratory diseases such as acute inflammation of the upper respiratory
tract, acute and chronic tracheitis, bronchitis and swelling and pain in throat, etc.
Contraindications:
The patients with bronchial asthma or acute emphysema are not recommended to use the device, please follow the doctor's
advice.
2.2 Features
Power supply: DC 5 V or 2 “AA” alkaline batteries
Input power: <3 VA
Nebulization rate: ≥0.25 mL/min
Noise: ≤50 dB
Equivalent volume particle diameter distribution: the occupation of small atomized particles (diameter < 5 μm) is no less than
90%.
Type of protection against electric shock: Class II
Degree of protection against electric shock: type BF applied part
Degree of protection against ingress of liquid: IP22
Note: please choose the power adapters manufactured by qualified companies(input: AC100-240V, 50Hz / 60Hz, output: DC5V,
1A).
The voltage of 2 “AA” alkaline batteries is DC3V.
2.3 Operational environment
Temperature: 5°C~40°C
Humidity: 15%~90%
Atmospheric pressure: 700hPa~1060hPa
Attention: This product is not suitable for use in strong electromagnetic interference environments (such as various medium/
high frequency therapeutic instruments, transformers, large electrical cabinets, radio and television transmission towers, other
radio frequency transmitting equipment, and other electrical appliances or medical equipment which may generate interference).
2.4 Principles
Principle of nebulization
The high-frequency vibration of piezoelectric ceramic plate directly leads to the deformation of microplate, making medication
in contact with the microplate extruded from it to form a mist spray effect. The mesh nebulizer is applicable for use in hospital,
clinic and family.
Principle of treatment
Respiratory system is an open system. The atomized medication, after inhalation, can be directly adsorbed on patient's oral
cavity, throat, trachea, bronchus and pulmonary alveoli, etc., through its mucous membrane absorption to achieve the purpose
of treatment.
