Spray type nasal irrigator

Abstract

The invention discloses a spray type nasal irrigator. The spray type nasal irrigator is designed according to nasal structures and surface characteristics of nasal mucosa of children. The spray type nasal irrigator comprises a nostril connector, a flow baffle, a separator, a pot body, an atomizing column, an atomizing cap, a switch button, an air through pipe, a base, an air inlet hole, a bottom cover, an up-down adjustment valve, a medicine liquid groove and a water liquid groove. When compressed gas flows through small holes in the upper end of the atomizing column from the air inlet, medicine liquid flows upward along a liquid guiding groove under the negative pressure effect and sprays out from the small holes of the atomizing cap, particles with an MMAD value of 48 micrometers are formed, and waste liquid flows back into the waste liquid groove. According to the spray type nasal irrigator, through the design of the liquid guiding groove in the nostril connector, it is guaranteed that the waste liquid can be introduced to the waste liquid groove under multiple possible operation conditions of children, the situation is avoided that children choke water due to stagnation of thewaste liquid, washing liquid cannot be washed to the throat, and pulmonary infection of children is avoided. The up-down adjustment valve is used for adjusting the pressure and fog droplet number so that the spray type nasal irrigator can be generally applied to clinical and convalescence treatment.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a spray nasal cavity irrigator. Background technique [0002] At present, the incidence of nasal diseases in China is very high, especially in children. Children's nasal diseases are closely related to asthma and chronic cough, and clinical attention is getting higher and higher. The treatment of nasal irrigation is based on Class Ia evidence and Class A recommendation, whether in foreign countries or in various domestic clinical treatment guidelines. However, the nasal cavity irrigation devices currently on the market are mainly water column irrigation, which is suitable for adults, and children are prone to choking water, and pediatricians do not recommend using them. [0003] Another type currently on the market is the nasal cavity nebulizer, which has a small particle value. When children breathe, it is easy to inhale the non-sterile nasal cavity washing liquid into the...

Problems solved by technology

[0003] Another type currently on the market is the nasal cavity nebulizer, which has a small particle value. When children breathe, it is easy to inhale the non-sterile nasal cavity washing liquid into the lungs, causing lung infection. In addition, the pressure and impact of the current nasal cavity nebulizer Inappropriate, easy to cause damage to the nasal mucosa or have no expected effect; when children operate, it is easy to completely plug the nasal connector of the nasal irrigator into the nostril, resulting in waste liquid not being able to flow out and flowing into the liquid tank from the spray hole to pollute the liquid or causing children to choke water;

[0004] At present, there are still problems in the nasal cavity nebulizers in the market: it is impossible to adjust the pressure and spray volume according to the clinical treatment needs. When the compressor driven by nasal cavity irrigation is turned off, the spray nasal cavity irrigator is likely to continue to spray small water droplets. cause drug waste
