Problems solved by technology

[0006] The embodiment of the present application provides a medical hearing aid suitable for otolaryngology, which solves the problem that the total ear canal hearing aid in the prior art is prone to occlusion effect and feedback whistle due to the closed ear canal, and cannot adapt to the full hard contact with the ear canal. The relative movement of the ear canal muscles affects the wearing stability and comfort of wearing, the three-dimensional complex physiological and anatomical structure of the ear canal makes it difficult to place in the deep ear canal, high cost, poor versatility, and cumbersome technical problems in the fitting process. The technical effect of slowing down the occlusion effect and feedback whistle of the total ear canal hearing aid to a certain extent, the loudspeaker of the hearing aid can be placed deep in the ear canal, the hearing aid and the ear canal are in soft contact, the cost of the hearing aid is low, the versatility is strong, and the fitting process is simple

Embodiment 1

[0072] Such as figure 1 As shown, the medical hearing aid applicable to otolaryngology of the present application includes a speaker part 100 , an airbag body 110 , a connecting device 200 , a body part 300 , a length adjustment component 400 and an air pump component 500 .

[0073] The speaker part 100 is used for sounding and hearing aid, and it includes a speaker body 120; the speaker body 120 plays the role of sounding;

[0074] The air bag body 110 includes a bag body protrusion 130 and a bag body one-way valve 140; the air bag body 110 covers the speaker main body 120, and the air bag body 110 is positioned with a bag body protrusion 130, the described The capsule protrusion 130 is hemispherical or a rectangular parallelepiped with excessive arcs, and the number is multiple, which is used to directly contact with the human ear canal skin to prevent the air capsule 110 from sealing the ear canal; the capsule is unidirectional The valve 140 is positioned on the airbag bod...

Embodiment 2

[0089] Considering that wearing a hearing aid for a long time will affect the comfort, it needs to be taken off regularly for secondary wearing, and the process is cumbersome; in view of the above problems, the embodiment of the present application adds a rope body rotation assembly 430 and a first capsule body positioning on the basis of the above embodiment component 220, the hearing aid user can rotate the first airbag body 111 without taking off the hearing aid through the said rope body rotating component 430 and the said first capsule body positioning component 220; The capsule positioning assembly 220 connects the first airbag body 111 rotatably and fixedly to the end of the connecting device away from the second airbag body 112; one end of the central rope 410 passes through the first The capsule body positioning assembly 220 is fixed on the first airbag body 111;

[0090]Preferably, the first capsule positioning assembly 220 includes a fixing ring 230 and a rope head ...

Embodiment 3

[0094] Considering that the user frequently rotates the central rope 410 in actual use, it is relatively boring and may have a certain impact on work and life (because rotating the first airbag body is equivalent to massaging the ear canal, it is more comfortable, and the user may Frequently take and rotate the center rope 410 to obtain a sense of comfort, frequent hand raising may have a certain impact on work and life);

[0095] In view of the above problems, the embodiment of the present application adds a rotating energy storage assembly 600 on the basis of the above embodiments, so as to realize the automatic rotation of the first airbag body 111 by rotating the central rope 410 once and for a long time;

[0096] Further, the rotating energy storage assembly 600 is as Figure 8 and Figure 9 It includes an energy storage assembly housing 610, an elastic body 620 and a one-way rotating energy storage assembly 630; the energy storage assembly housing 610 is fixed on the se...

Abstract

The invention discloses a medical hearing aid suitable for the otolaryngology department, the medical hearing aid comprises a loudspeaker part, a connecting device and a machine body part, the loudspeaker part comprises a loudspeaker main body, the machine body part comprises a machine body shell and a functional assembly, and the medical hearing aid further comprises an air bag body, a length adjusting assembly and an air pumping assembly; a bag body bulge and a bag body one-way valve are positioned on the air bag body; the air bag body comprises a first air bag body and a second air bag body, the first air bag body covers the loudspeaker main body, and the second air bag body covers the machine body part; the connecting device comprises a connecting hose which is communicated with the first air bag body and the second air bag body; the length adjusting assembly is used for adjusting the distance between the first air bag body and the second air bag body; and the air pumping assembly is used for inflating the air bag body. The technical effects that the blocking effect and feedback howling of the full-ear-canal hearing aid are relieved, the loudspeaker of the hearing aid can be placed in the deep ear canal, the hearing aid is in soft contact with the ear canal, the cost of the hearing aid is low, the universality is high, and the fitting process is simple and convenient are achieved.

Description

technical field [0001] The invention relates to the technical field of hearing aids, in particular to a medical hearing aid suitable for otolaryngology. Background technique [0002] A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain so that the sound can be felt. [0003] In the prior art, hearing aids generally ensure the quality of the output signal by increasing the power of the hearing aid, suppressing environmental noise, and eliminating sound feedback signals; It is difficult to effectively receive the required gain, and thus a better hearing aid effect cannot be obtained. [0004] The reason is that the speaker of the traditional hearing aid is far away from the patient's eardrum. Due to the interaction of sound wave conduction damping and reflection, it will cause the loss of sound during the conduction process in the ear...
