The treatment is mainly used to treat a variety of upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in the trachea, bronchial tubes, alveoli, and chest cavity. Nebulised inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. A nebulised inhaler is used to nebulise the medication into tiny particles, and the medication is deposited into the respiratory tract and lungs through respiratory inhalation, thus achieving painless and rapid treatment.
The size of the nebulised particles is directly related to the nebulisation effect. The size of the particles during nebulised inhalation determines its deposition site in the respiratory tract. Particle diameter 1~5um, precipitation site in the fine bronchial tubes and alveoli; diameter in 5~20um, precipitation in the bronchial tubes & upper respiratory tract; 20~40um, precipitation in the nose, pharynx, larynx and upper trachea. Therefore, it is necessary to choose different nebulisers according to the different respiratory diseases treated. In order to make the drugs work better, the nebulised particles that can reach the bronchial tubes and alveoli are usually chosen, so it is preferable to choose the nebuliser with nebulised particles ≤5um.
What are the nebulised drugs?
One category is bronchodilators and the other is hormonal drugs.
Bronchodilators are often used during an asthma attack and can relieve wheezing very quickly and do not need to be continued for a long time after the wheezing is relieved. Parents are more willing to accept this type of treatment as opposed to hormones. In the past, hormonal medications for asthma were taken orally, with high dosage and long dosage time, and obvious side effects. After changing to inhalation method of local medication, the amount of medication is reduced, the local effect, and the systemic side effects are very few.
In general, the use of hormonal drugs need to be determined according to the condition, because these drugs can reduce the sensitivity of the airways to external stimuli, thus reducing asthma attacks, controlling asthma fundamentally, and reducing irreversible damage to lung function due to recurrent asthma. Therefore, if your child suffers from asthma or allergic cough, it is best to follow your doctor's request for regular, long-term medication. Never take matters into your own hands and delay your child's treatment.
How to choose a nebuliser?
There are three types of medical nebulisers currently on the market, the mainstream types are compression nebulisers (gas compression air compression nebulisers) and ultrasonic nebulisers, and a mesh type nebuliser.
Ultrasonic Nebuliser
The use of piezoelectric conductive chip as a transducer, generating high-frequency vibration at the level of megahertz, the liquid will be broken up into fine particles of drug mist. The vibration process temperature is high, easy to change the activity of protein drugs, now on the market has basically been eliminated.
Compression nebuliser
The use of compressed gas impact atomised drugs or suspension, the formation of atomised particles. Noisy, large size, must be plugged into the power supply, mainly used in hospitals.
Mesh nebuliser
The circuit drives the metal mesh to oscillate at high speed, and the liquid is rapidly sieved through the tiny mesh holes on the mesh, forming countless atomised particles uniformly. It does not produce additional heat and airflow; the nebuliser sheet is used to vibrate the micro-mesh with periodically changing voltage, allowing the liquid to pass through the micro-mesh to nebulise the liquid, which can solve the noise problem of compressed nebuliser; the nebulised particles reach the medical grade.
At present, Audiowell has launched medical microporous nebuliser tablets, with fine and uniform nebulising particles, the nebulising particle sizes are all in the range of 1-5 microns, and the 2.5 micron particles account for about 80% of the total.
