Description

Technical Field

[0001] The utility model relates to the field of oral and nasal aerosol dispensers, in particular to a flat mouthpiece of an oral and nasal aerosol dispenser. Background Art

[0002] Oral and nasal aerosol applicators are suitable for treating respiratory diseases such as chronic bronchitis, tuberculosis, pneumonia, asthma, emphysema, viral airway infections, bronchiectasis, bronchial muscle obstruction, pharyngitis, and strep throat in children and the elderly. The subepithelial layer of the nasal and oral mucosa is rich in capillaries and lymphatic capillaries, making them more receptive to foreign drugs than skin and muscle. They rapidly deliver drugs to the circulatory and lymphatic systems, and can deliver drugs to the cerebrospinal fluid within minutes. Oral and nasal aerosol applicators are a medical device and drug delivery method developed specifically to take advantage of these characteristics of the human oral and nasal cavities. Using the principles of a nebulizer, an oral and nasal aerosol applicator converts the drug into a mist or powder that is easily absorbed and digested by the human body before administration to the patient, ensuring optimal, fastest, and maximum drug absorption.

[0003] However, traditional oral and nasal aerosol dispensers, such as the technical solution disclosed in the patent with application number CN202221779971.7 and invention name Oral and Nasal Aerosol Dispenser, have poor air tightness at the mouthpiece of the oral and nasal aerosol dispenser, and external bacteria and viruses can easily enter the oral and nasal aerosol dispenser through the mouthpiece, causing contamination of the oral and nasal aerosol dispenser.
