Ear canal air pressure balance type eardrum depression correction kit

Abstract

The invention relates to the field of medical instruments, in particular to an ear canal air pressure balance type eardrum depression correction kit. The ear canal air pressure balance type eardrum depression correction kit comprises an earmuff frame rod, an ear canal catheter structure and a nose catheter structure. An ear canal balloon of an ear canal catheter is inserted into an ear canal, a first balloon connector communicates with an earmuff balloon through a first balloon tube, gas is injected into the earmuff balloon, a second balloon connector communicates with the ear canal balloon through a second balloon tube, the nasal catheter is introduced from the inner part of a nasal cavity of a patient, the front end of the nasal catheter is enabled to enter the inner part of an ear tubeand reach the position, closest to a tympanic membrane, of the ear tube orifice, and inflating is carried out to enable an ear tube balloon to be full. At this time, the ear canal catheter and the nasal catheter are both fixed by separate balloons, the lower end of a second air pressure balance tube of the nasal catheter is tightly pressed and sealed, and the ear tube balloon inflates and isolatesthe ear tube, so that the rear side region of the tympanic membrane is in a closed state. Pumpback is carried out through an air pressure balancing connector, and the tympanic membrane returns to theoriginal shape under the action of air pressure difference at two ends, so that the tympanic membrane depression is effectively improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ear canal pressure-balanced eardrum depression correcting set. Background technique [0002] The eardrum is displaced in space due to external force or some reason, and is sunken inward, which is clinically called eardrum invagination. Invagination of the eardrum affects hearing. Because it is an organic displacement, the effect of taking medicine and injections is not good. Clinically, the doctor will instruct the patient to cover the ear tightly with the palm of the hand, and then release it quickly, causing a negative pressure in the ear canal. Air pressure, under the action of this negative air pressure, the eardrum bulges outward; or block the nostril with your fingers, hold your breath, and blow hard, so that a positive air pressure is generated inside the eardrum, and under the action of this positive air pressure, the eardrum bulges outward , to correct the inversion of...

Problems solved by technology

However, this method cannot completely block the inside of the patient's ear canal by relying solely on earplugs to form a closed state. At the same time, the method of using the pressurized ball recovery method is uncontrollable in the process of generating negative pressure. controlled damage
