The nebulizer is mainly used for the nebulization treatment of respiratory diseases such as throat and upper respiratory tract. Nebulizers are also divided into medical and household use. Household nebulizers allow patients to perform nebulization treatment at home to avoid cross-infection in hospitals. What is the principle of atomizer? What is the function of the atomizer? How to choose and use the atomizer? How to maintain and maintain the atomizer? Next, let’s learn about the knowledge of medical nebulizers.
1 What is a nebulizer
Nebulizer is our common medical device, and nebulizer is used more and more in clinic . Medical atomizers are mainly used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli and chest cavity. Atomization inhalation therapy is an important and effective treatment method in the treatment of respiratory system diseases. Atomization inhaler is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through breathing and inhalation, so as to achieve no pain. , quickly adapted to the purpose.
2 The role of nebulizers
Nebulizers can be used for the treatment of respiratory diseases, including asthma, chronic obstructive Pneumonia, chronic bronchitis and common cold, etc. It treats diseases by atomizing the drug into inhalable particles to deposit the drug in the respiratory tract. Compared with the traditional injection and taking medicine, this treatment method has a small dosage and effectively reduces side effects.
3 The principle of atomizer
There are two main principles of atomizer, one is ultrasonic atomizer , one is a compressed atomizer. The principle of the ultrasonic atomizer is to use electronic high-frequency oscillation (the oscillation frequency is 1.7MHz or 2.4MHz, which is beyond the range of human hearing, and the electronic oscillation is absolutely harmless to the human body and animals), through the high-frequency resonance of the ceramic atomizer, Disperse the molecular structure of liquid water to generate a natural and elegant water mist without heating or adding any chemical reagents. The principle of the compression atomizer is to use compressed air to form a high-speed airflow through a small nozzle, and the negative pressure generated drives the liquid or other fluids to be sprayed onto the barrier, and splashes around under the high-speed impact to turn the droplets into mist-like particles ejected from the outlet pipe.
4 Types of nebulizers
1. Ultrasonic nebulizer: Using the principle of ultrasonic, the liquid medicine is nebulized. The nebulizer of the ultrasonic nebulizer has no selectivity for the mist particles, so most of the generated drug particles can only be deposited in the upper respiratory tract such as the mouth and throat, and due to the small amount of deposition in the lungs, it cannot effectively treat lower respiratory tract diseases.
2. Air compression atomizer: also known as jet atomization, it is based on the principle of Venturi injection, using compressed air to form a high-speed airflow through a small nozzle, and the negative pressure generated drives the liquid Or other fluids are sprayed onto the block together, and splashed around under the high-speed impact to make the droplets turn into mist-like particles and ejected from the air outlet.
5 How to choose an atomizer
There are two main types of atomizers on the market, one is an ultrasonic atomizer, The other is an atomizer with an air pump and a compression pump. Different atomizers are aimed at different diseases. The quality of the nebulizer directly affects the treatment effect. If the nebulizer is used at will, the treatment will be ineffective at light, and the disease will be delayed at worst. “Those nebulizers on Taobao that cost only tens of yuan or hundreds of yuan definitely do not meet the requirements. Generally, upper respiratory tract problems, such as pharyngitis and rhinitis, can use ultrasonic nebulizers, while lower respiratory tract problems, such as pneumonia and asthma, should be selected. Compressed nebulizer. The size and quality of the nebulizer will directly affect the treatment effect. You should choose a regular brand and use an unqualified nebulizer, which will not only be ineffective, but will also delay the disease.
6 How to use the atomizer
1. Add distilled water to the water tank, the temperature is between 15-40 degrees, and the float in the water tank floats That’s it.
2. Put the liquid medicine in the atomizing tank, dilute it to 30-50 ml, tighten the lid of the tank, put the atomizing tank in the sink, and cover the tank tightly.
3. Turn on the power, turn on the power switch, the red indicator light will be on, preheat for about 3 minutes, then turn on the atomization switch, the white light is on, and the liquid will be sprayed out in mist
4. When inhaling, the mask should be placed on the nose and mouth, and open when exhaling.
5. The general use time is 15-20 minutes. After the end, turn off the atomizer first, then turn off the power switch, otherwise the electronic tube will be easily damaged, just pour out the water in the sink and wipe it clean.
7 Cleaning and maintenance of the atomizer
1. If there is no relevant disinfectant, and you are at home, after each operation, rinse the pipes and scald them with boiling water to dry.
2. If you want to disinfect with medicines, you can buy chlorine-containing preparations or disinfectant solutions at the pharmacy for half an hour, remove them, rinse them, and dry them for later use.
3. After the treatment is over, the nebulizer must be thoroughly disinfected to prevent infection in the next use, and the instrument must be kept dry.
4. Before using the nebulizer, the Clean and disinfect the cup that holds the medicine to prevent contamination.
5. When the atomizer is not used for a long time, the above method should also be used to clean, disinfect and dry before use.
8 Nebulizer Troubleshooting
When it is found that the compressed air nebulizer does not produce fog, the consumer first turns off the nebulizer switch, and removes the air tube from the nebulizer. Pull it out from the body, then turn on the atomizer switch, and use your fingers to approach the air outlet that was connected to the trachea to see if there is strong gas ejection from the air hole (this process will not cause any harm to people).
If it is found that the air outlet has only a slight gas ejection or no gas ejection, the consumer will turn off the atomizer again Switch, open the air inlet of the atomizer, take out the filter cotton inside, turn on the atomizer switch again, and confirm whether there is strong gas ejection from the air outlet of the atomizer. If there is a description, the filter cotton is contaminated and blocked. If the air intake hole is removed, the consumer only needs to replace the filter cotton. If there is only a slight gas ejection or no gas ejection, the consumer can observe with the naked eye whether the air intake hole is blocked, and remove any blockages. , If there is no blockage, it means that it is an internal failure of the body, and the manufacturer needs to be repaired.
