Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a nasal obstruction dosing device. BACKGROUND

[0002] Rhinitis, as a common upper respiratory tract disease, in recent years, the incidence rate in the global scope presents the sustained growth trend. Its typical symptom includes nasal obstruction, weeps, sneezes, hyposmia etc. seriously influence the life quality of patient. According to the incomplete statistics, the number of rhinitis patients in our country is close to 300 million, and this figure is still growing at an alarming rate. Rhinitis not only brings physical discomfort to patients, but also can cause a series of complications, such as otitis media, sinusitis, etc. further aggravate the disease.

[0003] In the process of treating rhinitis, drug instillation or drug spray is a common and direct way of administration. By directly instilling or spraying drugs into the nasal cavity, the drugs can quickly contact and act on the diseased site, thereby relieving symptoms such as nasal congestion, weeping, etc. However, this treatment method is also accompanied by a series of limitations and potential risks: 1. When the drug is instilled or sprayed into the nasal cavity, the concentration of the drug is often high because the drug directly acts on the nasal mucosa. High-concentration drugs can irritate the nasal mucosa, leading to mucosal hyperemia, edema, and even mucosal damage. Long-term repeated use of this damage can further exacerbate the situation, forming a vicious cycle; 2. After the drug is instilled or sprayed into the nasal cavity, it needs to be absorbed for a period of time to take effect. However, the absorption capacity of the nasal mucosa is limited, and the distribution of the drug in the nasal cavity is uneven, which leads to the fact that the effect of the drug is not long-lasting and it is difficult to ensure that the drug can fully act on the diseased site; 3. Since the effect of drug instillation or spray is short-lasting, patients often need to instill or spray the drug liquid into the nasal cavity repeatedly to maintain the therapeutic effect. This frequent use not only increases the pain and inconvenience of patients, but also may cause the patients to develop drug dependence. Once the drug is stopped, the symptoms may rebound quickly, or even worsen. SUMMARY
