The spiral cover structural design is also convenient for replacing the filtering sponge.
Further, a plurality of second through holes are formed in the hard vent pipe, the second through holes penetrate into the sleeve mounting channel, and the plurality of second through holes are correspondingly communicated with the plurality of first through holes respectively. The setting of first through-hole and second through-hole for the gaseous of stereoplasm breather pipe lets in can be through the cooperation of first through-hole and second through-hole, acts on the nasal cavity that corresponds with this breather pipe side from this breather pipe side, makes things convenient for the patient to use nasal cavity spraying to use medicine through the breather pipe, makes the function of this breather pipe richer.
And through the structural design of the first through hole and the second through hole, and the cooperation of the first through hole and the second through hole and the filtering sponge; the nasal obstruction relieving nasal cavity filter can filter inhaled air under the condition of relieving nasal obstruction, and the filtered air enters nasal mucosa from the first through hole and the second through hole to be humidified and heated, so that discomfort such as dry throat pain, irritating cough and the like is avoided.
The utility model has the beneficial effects that the surface of the vent pipe is uneven based on the arrangement of the plurality of first through holes on the side surface of the flexible sleeve, so that the contact compression area between the vent pipe and the nasal cavity can be reduced, and the probability of poor blood supply of the mucous membrane and even ischemic necrosis caused by contact compression of the nasal cavity can be reduced. And based on the arrangement that the side of the breather pipe contacted with the nasal cavity is provided with the flexible sleeve, the compression of the breather pipe to the nasal cavity can be further reduced.
