Description

Technical Field

[0001] The invention relates to the technical field of medical atomizers, and in particular to an atomizing device with controllable flow rate, flow velocity and particle size. Background Art

[0002] Atomization inhalation therapy is a treatment method that uses an atomization inhalation device to atomize the drug solution into aerosol particles with a particle size of 0.01 to 10 μm, which then enter the airway and deposit in the lungs through inhalation, thereby playing a role in preventing and treating diseases. In order to achieve this treatment goal, the corresponding atomization device is indispensable, which can convert the drug solution into an aerosol form and inhale the drug through the mouth (or nasal cavity) to achieve the treatment purpose.

[0003] Generally speaking, a nebulizer inhalation device with a large mist release per unit time can better exert its therapeutic effect. However, if a large amount of atomized droplets enter the body in a short period of time, it may cause pulmonary edema, and the dilution of airway secretions may also cause airway obstruction. If the nebulizer device is not thoroughly disinfected and dried, the contaminated reflux condensate may cause the nebulizer inhaler to be infected. In addition, the size and particle size distribution of the atomized particles directly affect the drug deposition site and the therapeutic effect. Summary of the invention

[0004] In view of the problems raised in the above background technology that during nebulization treatment, a large amount of nebulized droplets entering the body in a short period of time may cause pulmonary edema, and the airway secretions may be diluted, which may cause airway obstruction; the size and particle size distribution of the nebulized particles directly affect the drug deposition site and the treatment effect, a technical solution of a nebulizer with controllable flow rate and particle size is provided.

[0005] It includes a box body, a controllable airflow delivery mechanism is arranged on the right side of the inner cavity of the box body, a delivery port of the controllable airflow delivery mechanism is connected to an airflow delivery pipeline, and a liquid medicine delivery mechanism is arranged in the middle area of ​​the inner cavity of the box body, and the end of the liquid medicine delivery mechanism is inserted into the interior of the airflow delivery pipeline;

[0006] The airflow delivery pipeline includes an inner tube, a brass outer tube wrapped and fixed on the outer ring surface of the inner tube, and 10-12 electric heating plates adhered and fixed on the outer ring surface of the brass outer tube, and one end of the inner tube is connected to the delivery end of the controllable airflow delivery mechanism, and the other end is connected to a bellows that penetrates to the outside of the box body, and the end of the bellows away from the inner tube is connected to a nasal plug; specifically, after controlling the speed of the servo motor, the speed of the turbofan blades between the upper shell and the lower shell changes accordingly, so that the air volume and flow rate delivered by the air outlet duct become faster or slower. At this time, the airflow delivered to the inner tube will be mixed with the atomized medicine delivered by the conical collecting hood, and delivered to the patient's body with the help of the bellows and the nasal plug. Moreover, the nasal plug and the bellows are connected by internal and external threads, and the nasal plug can be replaced with a medical mask. Before the inner tube conveys the airflow and the atomized liquid medicine to mix, the electric heating plate heats the brass outer tube.
