As we all know, medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as sore throat, pharyngitis, bronchitis, asthma, fever, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli and chest cavity. The atomization inhalation therapy mainly uses the principle of gas jets to suspend the tiny mist droplets hit by water droplets in the gas to form an aerosol and enter the respiratory tract for humidification of the respiratory tract or drug inhalation. This method directly acts on the lesion. It has the advantages of small dose, quick effect, small side effects and convenient use, and has a significant curative effect. The local respiratory tract drug concentration is high, and the patient only needs to cooperate passively to ensure the efficacy of the drug.

In some cases, it can only be stopped halfway or when the dose needs to be increased, the needle body containing a certain amount of medicine can only be replaced in addition, which will hinder the curative effect and affect the patient's condition; At the same time, the only source of gas is atomized gas. Practice shows that these gases are often thin. Therefore, when patients do not let go of their mouths, they must feel suffocated when they breathe repeatedly, so they need to open their mouths frequently to make the treatment more compliant. Greatly reduced; the traditional medical nebulizer mainly includes an ultrasonic generator, a water tank and a crystal transducer, an atomization tank and a sound-permeable membrane, an output tube and a mouthpiece or a mask, and put the mouthpiece into the patient when nebulizing Put the mask in the mouth or put the mask on the patient's mouth and nose. During the nebulization process, it is necessary to keep the spray tube at a level or lower than the airway inlet, and place the atomized water droplets to choke and cause suffocation. Due to the mouth or the direction of the spray tube At the same level, for patients who can only lie down, it is very inconvenient for patients or their family members to hold their mouths or masks in their hands for atomization.

Therefore, it is necessary to improve the existing medical nebulizer, so that the improved medical nebulizer can continuously administer medicine, which can not only ensure the patient's free breathing, but also ensure that the atomization chamber is automatically sealed when exhaling, effectively preventing the nebulization The liquid medicine leaks out of the suction tube, which is convenient to use.
