Description

Nasal cavity sprayer for otolaryngological department

Technical Field

The invention relates to the technical field of medical instruments, in particular to a nasal sprayer for an otolaryngological department.

Background

Currently, the "otorhinolaryngological" family is the surgical family of diagnosis and treatment of the ear, nose, pharynx, larynx, and their associated head and neck regions.

Because of serious environmental pollution in cities and complex working environment, the number of people suffering from rhinitis in modern people is more and more, and the nasal cavity sprayer for treating the rhinitis is a good choice, and can flush the nasal cavity, promote wound healing, and relieve nasal discomfort symptoms such as nasal dryness, epistaxis, nasal obstruction, nasal itching, watery nasal discharge and the like.

In the prior patent (cn201910973493.x), a nasal cavity sprayer for otorhinolaryngological department is disclosed, which can block the nasal cavity of a patient to prevent the liquid medicine sprayed into the nasal cavity of the patient from rapidly flowing out of the nasal cavity of the patient, i.e., the device can slowly flow the liquid medicine sprayed into the nasal cavity of the patient out of the nasal cavity of the patient, and can collect the liquid medicine slowly flowing out of the nasal cavity of the patient to prevent the flowing liquid medicine from flowing around; the medicine is cleaned in the nasal cavity while flowing out, the bent structure has more dead corners to cause difficulty in cleaning, living space is left for germs, and meanwhile, the germs under the liquid medicine belt stay at the plugging part in a short time in a plugging mode to cause adhesion of the germs, so that the cleaning effect of the liquid medicine cannot achieve the expected effect;

in the prior patent (cn202211375807.x), a nasal cavity sprayer is disclosed, through setting up a plurality of atomizing orifices that incline each other, make it when using, the water smoke of spouting from a plurality of atomizing orifices can strike together, thereby make the blowout water smoke scatter, make the more tiny dispersion of fog, and the water smoke of blowout strikes together, can consume a bit of water smoke spun kinetic energy, thereby when water smoke spouts the patient's nasal cavity inner wall, can reduce the impact force of water smoke to nasal cavity inner wall, and then reduce patient's uncomfortable, reduce the possibility that the user rejected resistance. But make a plurality of drops fuse each other through a plurality of atomizing orifice water spray striking, lead to atomizing drop of water to mix the grow, and the drop of water mobility of grow increases for the liquid medicine is shorter at the time of nasal cavity inner wall dwell, is difficult to reach the effect of clearance and medicine loading.
