Spiral-flow type nasal cavity cleaning instrument

Abstract

The invention relates to a spiral-flow type nasal cavity cleaning instrument. The instrument comprises a vessel, a spray pipe and an air inflation device, wherein a water outlet of the vessel is connected with a water inlet of the spray pipe through a water delivery pipe, the side wall of the spray pipe is provided with a plurality of nozzles, an air outlet of the air inflation device is connectedwith an air inlet of the vessel through an air delivery pipe, a distribution area of the nozzles in the side wall of the spray pipe comprises all pipe walls within a section of distance on the frontportion of the spray pipe, the front end of the spray pipe is a head of the spray pipe, the head of the spray pipe is provided with a plurality of nozzles, the tail portion of the spray pipe is internally provided with a spiral flow diversion propulsion device used for forming spiral flow, when fluid flows forward, a pipe body of the spray pipe is driven to rotate relative to a fixing seat, the spray pipe is internally provided with a coaxial inner pipe, and the inner pipe is located between the spiral flow diversion propulsion device and the head of the spray pipe in the axial direction. Thespiral-flow type nasal cavity cleaning instrument has the advantages that the flushing effect of the cleaning instrument is good, the area is large, the use is convenient, the cleaning instrument is mainly used for cleaning the nasal cavity and can be used as a daily sanitary product and medical equipment.

Description

technical field [0001] The invention relates to a swirling flow nasal cavity cleaning instrument, which is mainly used for cleaning the nasal cavity and can be used as a daily hygiene product and a medical device. Background technique [0002] Flushing with water is an effective way to clean the nasal cavity. In the prior art, the utensil for cleaning the nasal cavity is a nasal lavage device. The specific forms of the nasal lavage device are various, but the basic structure is mainly a flexible pot that can hold water, which is connected by a catheter. The nozzle made of hard material, one or several spouts are opened on the top of the nozzle, when the flexible pot is squeezed by hand, under the action of pressure, the water passes through the conduit and enters the nozzle, and finally sprays out from the spout. The tube is inserted into the nasal cavity to spray water, relying on the flushing effect of the spray water to wash away the foreign matter (dirt) adhering to the ...

AI Technical Summary

Problems solved by technology

[0004] The defects of existing nasal washers are mainly manifested in: the first is that the spout is only arranged on the front end of the nozzle, and the flushing surface of the water spray is small, so it is necessary to hold the nozzle to clearly clear each part of the nasal cavity one by one, which is time-consuming and troublesome; The flushing direction is close to vertical, and the force on the foreign matter bonded to the nasal cavity is mainly pressure, which is not conducive to the peeling off of foreign matter; third, it is not conducive to maintaining a stable spray pressure, which is not easy to control the water flow, affects the flushing effect, and is easy to drown
