Description

Ear-nose comprehensive treatment equipment

Technical Field

The invention relates to the field of ear canal disease treatment equipment, in particular to ear-nose comprehensive treatment equipment.

Background

Otitis media is an inflammatory lesion involving the middle ear, including all or part of the structures of eustachian tube, tympanic cavity, tympanum and mastoid chamber, is good for children, mainly shows symptoms of earache, purulence, tympanic membrane perforation, hearing loss and the like, and can cause deafness of different degrees. If water is accumulated in the tympanic cavity or the body has poor immunity and is susceptible to cold, otitis media can be recurrent, and great pain is brought to patients. The traditional Chinese medicine theory considers that the ear canal inflammation is caused by damp-heat in liver and gallbladder, excessive fire pathogen and qi and abnormal liver channel. Bacterial infections, water ingress into the ear canal, and prolonged use of large volume earphones all cause otitis media. In addition, as the nasal cavity is communicated with the auditory canal through the eustachian tube, when the nasal cavity has inflammation, if the drainage direction of the nasal sinuses is changed, bacteria can reach and infect the middle ear through the eustachian tube, thereby causing secretory otitis media, and researches show that nearly half of otitis media has direct relation with the inflammation of the nasal cavity.

The existing treatment of otitis media mainly adopts pharmacotherapy, and the treatment policy is to eliminate focus, perforate or puncture tympanic membrane, discharge effusion and prevent secondary infection. However, otitis media is not a disease caused by one cause, and if the treatment is performed only on ears, the due treatment effect is difficult to achieve. If the nasal cavity, the auditory canal and the eardrum can be comprehensively treated, the repeated attack of the otitis media can be prevented well.
