Spray type nasal irrigator

Abstract

The present invention is a spray nasal irrigator designed according to the structure of children's nasal cavity and the surface characteristics of nasal mucosa, including nostril connector, baffle plate, separator, tank body, atomizing column, atomizing cap, switch button, and ventilation tube , the base, the air inlet, the bottom cover, the upper and lower regulating valves, the liquid medicine tank, and the waste liquid tank; when the compressed gas flows through the small hole at the upper end of the atomizing column from the air inlet hole, the medicine liquid is guided along the liquid under the action of negative pressure. The tank flows upwards, and then is sprayed out through the small hole of the atomizing cap to form particles with an MMAD value of 48 microns, and the waste liquid flows back into the waste liquid tank; the present invention ensures that the children are in the middle of many times through the design of the drainage tank at the nasal joint. Under all possible operating conditions, the waste liquid can be drained to the waste liquid tank, avoiding children choking on water caused by the retention of waste liquid, the flushing liquid will not be washed into the throat, and avoiding children's lung infection. The upper and lower adjustment valves are used to adjust the pressure and the number of mist particles, making the spray nasal irrigation device commonly used in clinical and recovery 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
