Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a medical nebulizer. Background Technology

[0002] Nebulizers are important devices used for bronchial disinfection and treatment. They are used to treat respiratory diseases such as cough, asthma, and bronchitis. By generating a mist of medication and delivering it into the body through a catheter, the medication can directly reach the affected area and is easily absorbed.

[0003] However, the pore size on the atomizing plate is only between 0.5μm and 5μm, making it very easy to get clogged, which will cause the atomizer to stop working. Maintenance requires replacing the atomizing plate or the entire atomizing module, and replacement can easily damage parts, resulting in high operating costs.

[0004] This utility model relates to our company's products, with application numbers CN201920675450.9 and CN201921469036.9, entitled "A Handheld Medical Nebulizer" and CN201921469036.9, entitled "Problems Existing in the Use of a Handheld Nebulizer." Due to the complex internal structure of its nebulization components, these devices are difficult to manufacture, disassemble, clean, and maintain, and are prone to damage, resulting in high operating costs and a poor user experience. Therefore, only continuous product updates and improvements can ensure product competitiveness. This utility model further optimizes the internal component structure and connection method of the nebulizer component, adding a threaded connection method to the original snap-fit ​​connection method. This overcomes the problems of existing products having relatively simple connection methods for the nebulizer box and spray tube, resulting in low adaptability and limited user choices. During production, various specifications can be manufactured according to different user requirements, greatly improving the product's adaptability and application range, enhancing market competitiveness and user experience, and achieving better economic benefits.
