Ear protection device capable of effectively insulating sound and used for ear-nose-throat department nursing

Abstract

The invention discloses an ear protection device capable of effectively insulating sound and used for ear-nose-throat department nursing, and relates to the technical field of ear-nose-throat department nursing, the ear protection device comprises a plastic hanging ring and two protection covers, the two protection covers are fixedly installed at the ends of the plastic hanging ring respectively, and noise reduction cotton layers are bonded to the inner side walls of the protection covers. A silicon rubber sleeve ring is bonded to the edge of the surface of the noise reduction cotton layer, an earplug is inserted into the middle of the noise reduction cotton layer, a storage barrel is fixedly connected to the middle of the outer side wall of the protective cover, electrorheological fluid is arranged on the inner side wall of the storage barrel, and a conductive sleeve is fixedly connected to one side of the storage barrel. According to the ear protection device capable of effectively insulating sound and used for ear-nose-throat department nursing, the earplugs are conveniently inserted into the ears of a patient, the earplugs are tightly attached to the inner walls of the ears of the patient after electrorheological fluid is added, and the electrorheological fluid is changed into a solid state from a liquid suspension after being electrified, so that sound insulation sealing is conducted on ear canals; meanwhile, the viscosity of the electrorheological fluid can be changed through the size of the input electric field, and the sound insulation strength is adjusted.

Description

technical field [0001] The invention relates to the technical field of otolaryngology nursing, in particular to an ear protection device for otolaryngology nursing which can effectively insulate sound. Background technique [0002] When otolaryngology patients perform postoperative ear care (especially after eardrum repair surgery), they should avoid sudden disturbance of the whistle in the external environment during the recovery period, and avoid working in a noisy environment, so as to ensure the repaired eardrum To avoid secondary damage caused by large shocks, it is necessary to protect the repaired eardrum to avoid the stimulation of noise to the eardrum, and it is necessary to increase the sound insulation effect on the protective device. [0003] Chinese Patent Announcement No. CN213607424U discloses an effective sound-insulating ear protection device for ENT care, which is basically described as: comprising a plastic hanging ring, a sponge strip, a plastic movable b...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an effective sound-insulating ear protection device for ear-nose-throat care, which solves the problem that the sound-insulation effect in the above-mentioned background technology is in a fixed state and is inconvenient to adjust
