Description
Technical Field
The invention belongs to the technical field of atomization, and particularly relates to a medical atomization treatment device.
Background
For respiratory diseases, in recent years, aerosol therapy has a relatively obvious therapeutic effect and is widely accepted by medical staff. The solution is atomized into tiny droplets to carry medicine particles to float in the air, and the droplets are sucked into the oral cavity and the nasal cavity of a patient through the mouth and the nose of the patient to enter the respiratory tract and the bronchus and further reach the inside of the whole alveolus. The atomized liquid drops are deposited and attached to the oral cavity, the nasal cavity, the bronchus and the lung to be fully absorbed by patients, and the action effect of the medicine is improved to a great extent. For bronchial asthma, the aerosol inhalation administration mode is the most effective prevention and treatment method at present. Meanwhile, for chronic pharyngolaryngitis, acute and chronic bronchitis, bronchiectasis, allergic rhinitis, chronic obstructive pulmonary disease and the like, inhalation therapy can produce a treatment effect efficiently, quickly and painlessly, and the characteristics are particularly important for the old and infants. Different from conventional administration, the medicinal fog drops can directly act on the lung, have stronger pertinence, and can be directly absorbed by the lung in a non-invasive administration mode without causing damage to human bodies. Nebulization delivers drugs directly to the lungs without first-pass action on the liver. The lung contains hundreds of millions of alveoli, which provide a large drug absorption area, and the alveoli have thin epidermis and a large number of capillaries, which are helpful for drug absorption. Therefore, the atomization treatment has good treatment effect on respiratory diseases. The atomization treatment is not only limited to respiratory diseases, but also has wide application in the treatment of diseases of other parts of eyes, faces and the like.
The droplets enter the nasal cavity and float with the airflow, and the size of the droplet particles determines the location where they can ultimately reach. Generally, the larger the volume and the larger the mass of the particles, the shorter the movement distance, and the large particle droplets are mainly deposited in the upper respiratory tract parts such as the oral cavity, the throat, the bronchus and the like, and are mainly used for treating the upper respiratory tract diseases. The small particle fog drops can enter the lung along with airflow and are mainly used for treating lower respiratory tract diseases. At present, the atomizing device can only produce fog drops with fixed particle size, namely, the atomizing device only has treatment effect on fixed parts.
The large-particle fog drops are easy to prepare, while the atomization device for preparing the small-particle fog drops in the current market has limited atomization effect and simple atomization structure, the obtained fog drops still have a plurality of large-particle fog drops, the treatment effect is reduced, and the targeting property of the medicine is lower. The small particle fog drops can smoothly enter the lung to treat lower respiratory tract diseases, and have good treatment effect on infants with small tracheitis.
At present, scales are arranged on the side surface of a traditional Chinese medicine cup of an atomizing device, and a patient injects the medicine dosage according to the scales. For the elderly patients, the eyesight is weak, and the operation of injecting the medicament cannot be completed. Meanwhile, the liquid level of the medicament also needs to be observed every time the medicament is injected by an adult, which brings great inconvenience to the medicament injection operation.

The large-particle fog drops are prepared by the two-stage atomization process of swirl atomization and nozzle atomization, so that the treatment of upper respiratory diseases is realized. The micro-particle fog drops are prepared by three atomization flows of rotational flow atomization, collision atomization and nozzle atomization, so that the treatment of lower respiratory diseases is realized. The three-stage atomization process can effectively reduce the particle size of the fog drops and prepare the micro-particle fog drops.
