Description

Technical Field

[0001] The utility model relates to the technical field of nasal resistance detection, in particular to a mask suitable for nasal resistance detection and a nasal resistance detector. Background Art

[0002] Nasal congestion is a subjective feeling of nasal ventilation dysfunction, and its etiology is complex. Lesions of the nasal cavity and paranasal sinuses themselves, such as anatomical abnormalities, infection, allergic reactions, and space-occupying lesions, can affect the nasal ventilation function and cause nasal congestion. Some drug effects, physiological and psychological factors are also important factors affecting nasal congestion. Nasal congestion has the characteristics of intermittent, alternating, paroxysmal, progressive or continuous attacks, and can occur on one or both sides. The incidence rate is high, and it is one of the most common symptoms in the clinical work of otolaryngology.

[0003] At present, the degree of nasal congestion is mostly assessed by subjective methods. The Visual Analogue Scale (VAS) can quantify subjective feelings, but it still cannot objectively reflect the state of nasal ventilation function. Nasal resistance is one of the important contents of clinical examination in otolaryngology. The nasal resistance meter is widely used in the clinical assessment of nasal ventilation status due to its good repeatability, convenience and non-invasiveness. Existing nasal resistance masks have the following problems:

[0004] (1) During the testing process, the user needs to hold the mask with his hands to avoid air leakage, which is inconvenient for the user and requires the user's cooperation. If the user does not cooperate well, the test results will be affected;

[0005] (2) After the test, the mask often causes facial skin indentations due to long-term pressure on the face;

[0006] (3) A nasal resistance meter is usually equipped with a silicone mask, which cannot be sterilized repeatedly. In addition, repeated high-temperature sterilization may cause the silicone to age and become brittle, reducing its airtightness, making it unsuitable for repeated high-temperature sterilization.
