Hearing aid capable of being used for vagus nerve stimulation

Abstract

The invention relates to a hearing aid capable of being used for vagus nerve stimulation, which is characterized in that a supporting assembly is hung on the head of a user, at the moment, a first hearing aid is placed in one ear of the user for hearing aid, and a first electrode plate is attached to the vagus nerve part of one ear of the user. The second hearing aid is placed in the other ear of the user and used for hearing aid, and the second electrode plate is attached to the vagus nerve part of the other ear of the user. When the supporting assembly is worn, the first maintaining assembly and the second maintaining assembly are both converted from the unused state to the unused state, and at the moment, the supporting assembly is more firmly worn on the head of a user through the first maintaining assembly and the second maintaining assembly. And the first maintaining assembly and the second maintaining assembly can be switched from the use state to the non-use state by stretching the supporting assembly after a period of time, so that the situation that the first maintaining assembly and the second maintaining assembly extrude the same position of the head of the user for a long time is avoided.

Description

Technical Field

[0001] The present application relates to the technical field of hearing aids, and in particular to a hearing aid that can be used for vagus nerve stimulation. Background Art

[0002] Hearing aids are small electronic devices designed for people with hearing loss. They amplify sound and enhance speech clarity, helping users better perceive ambient sounds and communicate. They are not only hearing aids but also crucial devices for improving quality of life and promoting social participation.

[0003] The ear is home to peripheral branches of the vagus nerve. Electrical or mechanical stimulation of these areas can indirectly activate the vagus nerve. Specifically, the stimulation signal is transmitted through the vagus nerve to the brainstem, influencing the hypothalamus, limbic system, and cerebral cortex, regulating autonomic balance, inhibiting inflammatory responses, and regulating endocrine function.

[0004] Currently, existing hearing aids or ear vagus nerve stimulation devices may fall off or shake due to vibrations generated by the user's limb movements during use. By placing the hearing aid and electrode pads on an ear-hook structure and hanging it on the user's head, the ear-hook structure is used to clamp the user's head to provide a stable wearing experience. However, long-term compression and wearing will cause discomfort to the wearer's head. Summary of the Invention

[0005] Based on this, it is necessary to provide a hearing aid that can be used for vagus nerve stimulation to address the problem that the traditional hearing aid and electrode plates are set on an ear-hook structure and hung on the user's head, and the ear-hook structure is used to clamp the user's head to provide stable wearing, but long-term compression wearing will cause discomfort to the wearer's head.

[0081] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0082] like Figures 1 to 2 As shown, in one embodiment of the present application, the hearing aid that can be used for vagus nerve stimulation includes: a first hearing aid 11, a first electrode sheet 12, a second hearing aid 13, a second electrode sheet 14, a supporting component 15, a first maintaining component 16 and a second maintaining component 17.

[0083] The first hearing aid 11 is placed in one ear of the user.

[0084] The first electrode sheet 12 is disposed on the first hearing aid 11 and is used to electrically stimulate the vagus nerve on one ear of the user.

[0085] The second hearing aid 13 is placed on the other ear of the user.

[0086] The second electrode sheet 14 is disposed on the second hearing aid 13 and is used to electrically stimulate the vagus nerve on the other ear of the user.

[0087] The support assembly 15 is hung on the user's head, one end of the support assembly 15 is fixedly connected to the first hearing aid 11, and the other end of the support assembly 15 is fixedly connected to the first hearing aid 11; the support assembly 15 at least partially abuts against the user's head.

[0088] The first maintaining component 16 is disposed on the supporting component 15 . The first maintaining component 16 is disposed close to the first hearing aid 11 . The first maintaining component 16 abuts against the user's head.

[0089] The second retaining component 17 is disposed on the supporting component 15 . The second retaining component 17 is disposed close to the second hearing aid 13 . The second retaining component 17 abuts against the user's head.

[0090] The first maintaining component 16 and the second maintaining component 17 both have an in-use state and an unused state, and when the first maintaining component 16 and the second maintaining component 17 are both in the in-use state, the first maintaining component 16 and the second maintaining component 17 respectively squeeze the two sides of the user's head; when the first maintaining component 16 and the second maintaining component 17 are both converted from the in-use state to the unused state, the first maintaining component 16 and the second maintaining component 17 slide a certain distance relative to the support component 15, so that the squeezing positions of the first maintaining component 16 and the second maintaining component 17 on the user's head are different in two consecutive use states.

[0091] The structure of the first maintaining assembly 16 is the same as that of the second maintaining assembly 17 .

[0092] Specifically, the first hearing aid 11 includes a first receiver 111, which is inserted into the user's ear canal. The first electrode sheet 12 is arranged on one side of the first receiver 111. The first hearing aid 11 is provided with a first matching groove 112, which is arranged between the first receiver 111 and the first electrode sheet 12.

[0093] The second hearing aid 13 includes a second receiver 131, which is inserted into the user's ear canal. The second electrode sheet 14 is arranged on one side of the second receiver 131. A second matching groove 132 is opened on the second hearing aid 13, and the second matching groove 132 is arranged between the second receiver 131 and the second electrode sheet 14.

[0094] The first hearing aid 11 and the second hearing aid 13 both contain other electronic components to enable the first hearing aid 11 and the second hearing aid 13 to perform their hearing aid functions. Furthermore, the first electrode 12 and the second electrode 14 are both connected to a power supply and a control chip to stimulate the first electrode 12 and the second electrode 14. Therefore, these components will not be described in detail here.

[0095] In this embodiment, the support assembly 15 is first hung on the user's head, with one end of the support assembly 15 hung on one ear and the other end of the support assembly 15 hung on the other ear. The first hearing aid 11 is then placed in one ear for hearing assistance, and the first electrode 12 is attached to the vagus nerve site on one ear for vagus nerve stimulation. The second hearing aid 13 is then placed in the other ear for hearing assistance, and the second electrode 14 is attached to the vagus nerve site on the other ear for vagus nerve stimulation. When the support assembly 15 is worn, the first retaining assembly 16 and the second retaining assembly 17 are both switched from an unused state to an unused state. The first retaining assembly 16 and the second retaining assembly 17 securely secure the support assembly 15 to the user's head. The support assembly 15 can be stretched periodically to switch both the first retaining assembly 16 and the second retaining assembly 17 from an used state to an unused state, thereby preventing the first retaining assembly 16 and the second retaining assembly 17 from pressing against the same location on the user's head for extended periods of time.

[0096] like Figures 3 to 7 As shown, in one embodiment of the present application, the support assembly 15 includes: a first bracket 151 , a second bracket 152 and an adjustment assembly 153 .

[0097] The first bracket 151 is disposed on one side of the user's head, and the first bracket 151 is hung on the user's ear.

[0098] The second bracket 152 is disposed on the other side of the user's head, and the second bracket 152 is hung on the user's ear.

[0099] The adjustment assembly 153 is disposed between the first bracket 151 and the second bracket 152 . The first bracket 151 is inserted into the adjustment assembly 153 , and the second bracket 152 is inserted into the adjustment assembly 153 .

[0100] The adjustment assembly 153 is used to lock the insertion depth of the first bracket 151 and the second bracket 152 therein.

[0101] Specifically, the first bracket 151 includes a first ear hanging portion 151a and a first hanging head portion 151b. The first ear hanging portion 151a is used to be hung on the user's head. The first ear hanging portion 151a is fixedly connected to the first hanging head portion 151b. The first hanging head portion 151b is inserted into one end of the adjustment component 153.

[0102] The second bracket 152 includes a second ear hanging portion 152a and a second hanging head portion 152b. The second ear hanging portion 152a is used to be hung on the user's head. The second ear hanging portion 152a is fixedly connected to the second hanging head portion 152b. The second hanging head portion 152b is inserted into the other end of the adjustment component 153.

[0103] In this embodiment, the depth of the first hanging portion 151b and the second hanging portion 152b inserted into the adjustment component 153 is synchronously adjusted to thereby adjust the size of the entire support component 15 so that the support component 15 can be adapted to different users.

[0104] like Figures 8 to 9 As shown, in one embodiment of the present application, the adjustment assembly 153 includes: a support tube 153a, a locking member 153b and a reset member 153c.

[0105] The first bracket 151 is inserted into one end of the support tube 153 a , and the second bracket 152 is inserted into the other end of the support tube 153 a , so that the first bracket 151 abuts against the second bracket 152 .

[0106] The locking member 153b is slidably disposed in the middle of the support tube 153a. The locking member 153b is disposed between the first bracket 151 and the second bracket 152. The locking member 153b is inserted into the first bracket 151 and the second bracket 152.

[0107] The reset member 153c is fixedly disposed on the support tube 153a, one end of the reset member 153c is fixedly connected to the locking member 153b, and the other end of the reset member 153c is in contact with the locking member 153b.

[0108] In this embodiment, the locking member 153b is pushed to remove the portion of the locking member 153b inserted into the first bracket 151 and the second bracket 152, thereby allowing the first bracket 151 and the second bracket 152 to slide relative to each other. When the locking member 153b is reinserted into the first bracket 151 and the second bracket 152, the first bracket 151 and the second bracket 152 are locked in position.

[0109] like Figures 10 to 12 As shown, in one embodiment of the present application, the locking member 153 b includes: a first support rod 18 , a pressing plate 19 , a locking gear 20 and an unlocking gear 21 .

[0110] The first support rod 18 is slidably disposed in the middle of the support tube 153 a , and the first support rod 18 is disposed between the first bracket 151 and the second bracket 152 .

[0111] The pressing plate 19 is disposed on one side of the supporting tube 153 a , and the pressing plate 19 is fixedly connected to one end of the first supporting rod 18 .

[0112] The locking gear 20 is fixedly connected to the other end of the first support rod 18 . The locking gear 20 is inserted into the first bracket 151 . The locking gear 20 is also inserted into the second bracket 152 .

[0113] The unlocking gear 21 is disposed between the locking gear 20 and the pressing plate 19 . The unlocking gear 21 is rotatably disposed on the first support rod 18 . The unlocking gear 21 is disposed between the first bracket 151 and the second bracket 152 .

[0114] Specifically, a plurality of tooth grooves are uniformly formed on the end surface of the first bracket 151 near the locking gear 20, so that the locking gear 20 can be inserted into the tooth groove on the first bracket 151, and the unlocking gear 21 can also be inserted into the tooth groove on the first bracket 151. A plurality of tooth grooves are also uniformly formed on the end surface of the second bracket 152 near the locking gear 20, so that the locking gear 20 can be inserted into the tooth groove on the second bracket 152, and the unlocking gear 21 can also be inserted into the tooth groove on the second bracket 152.

[0115] In this embodiment, by pressing the pressing plate 19, the first support rod 18 drives the locking gear 20 to exit the first bracket 151 and the second bracket 152, and also drives the unlocking gear 21 to enter between the first bracket 151 and the second bracket 152. Since the unlocking gear 21 can rotate, the first bracket 151 and the second bracket 152 can move relative to each other.

[0116] like Figures 8 to 12 As shown, in one embodiment of the present application, the reset member 153 c includes: a first reset plate 22 and a second reset plate 23 .

[0117] The first reset plate 22 is arranged on one side of the first support rod 18 . The first reset plate 22 is arranged to be inclined. One end of the first reset plate 22 is fixedly connected to the support tube 153 a , and the other end of the first reset plate 22 is abutted against the pressing plate 19 .

[0118] The second reset plate 23 is arranged on the other side of the first support rod 18 , and the second reset plate 23 is arranged to be inclined. One end of the second reset plate 23 is fixedly connected to the support tube 153 a , and the other end of the second reset plate 23 is abutted against the pressing plate 19 .

[0119] In this embodiment, when the pressing plate 19 is released, the combined elastic restoring force of the first reset plate 22 and the second reset plate 23 resets the pressing plate 19. The synchronous first support rod 18 then drives the locking gear 20 back into position between the first bracket 151 and the second bracket 152, and drives the unlocking gear 21 out of the first bracket 151 and the second bracket 152, thereby fixing the positional relationship between the first bracket 151 and the second bracket 152.

[0120] like Figures 4 to 14 As shown, in one embodiment of the present application, the first maintaining component 16 includes: a first contact member 161 , a first limiting member 162 , a second limiting member 163 , a first limiting groove 164 and a second limiting groove 165 .

[0121] The first contact member 161 is slidably disposed on the first bracket 151 , and the first contact member 161 abuts against the user's head.

[0122] The first limiting member 162 is fixedly disposed on the first bracket 151 , and the first limiting member 162 is slidably connected to the first contact member 161 .

[0123] The second limiting member 163 is slidably disposed on the first bracket 151 , and the second limiting member 163 is inserted into the first contact member 161 .

[0124] The first limiting groove 164 is provided on one side of the first contact member 161 , and the first contact member 161 is inserted into the first limiting groove 164 .

[0125] The second limiting groove 165 is disposed on the other side of the first contact member 161 , and the first contact member 161 is inserted into the second limiting groove 165 .

[0126] Specifically, the structure of the first limiting slot 164 is identical to that of the second limiting slot 165. The first limiting slot 164 includes a first slot 164a, three second slots 164b, and three third slots 164c. The length of the first slot 164a extends parallel to the plumb bob. The three second slots 164b are located on the side of the first slot 164a away from the user's head and are connected to the first slot 164a. The three second slots 164b are equidistantly spaced along the length of the first slot 164a, with each second slot 164b extending perpendicularly to the length of the first slot 164a. Each third slot 164c is located at the bottom of a second slot 164b. The top of each third slot 164c is connected to a second slot 164b, and the bottom of each third slot 164c is connected to the first slot 164a. The three third slots 164c are arranged at an angle and are parallel to each other.

[0127] A first rotating plate 24 is rotatably positioned at the connection point between each second slot 164b and third slot 164c. When the first contact member 161 slides from the first slot 164a to the second slot 164b, it pushes the first rotating plate 24 to rotate, sealing the third slot 164c. After the first contact member 161 passes through the first rotating plate 24, the first rotating plate 24 returns to its original position, preventing the first contact member 161 from entering the first slot 164a from the second slot 164b. Specifically, the first rotating plate 24 is tilted in the second slot 164b, and a torsion spring is provided at the rotating shaft of the first rotating plate 24 to facilitate its return.

[0128] A second rotating plate 25 is rotatably provided at the position in the first groove 164a that is connected to the second groove 164b. The second rotating plate 25 is used to prevent the first contact member 161 from sliding from the top of the first groove 164a to the bottom of the first groove 164a, and the second rotating plate 25 will not prevent the first contact member 161 from sliding from the bottom of the first groove 164a to the top of the first groove 164a.

[0129] like Figure 6 As shown, in one embodiment of the present application, the first contact member 161 includes: a limiting plate 161a, a matching block 161b and a contact plate 161c.

[0130] The limiting plate 161 a is slidably disposed on the first bracket 151 , and the second limiting member 163 is inserted into the limiting plate 161 a .

[0131] The matching block 161 b is slidably disposed on the limiting plate 161 a , and the matching block 161 b is slidably connected to the first limiting member 162 .

[0132] The contact plate 161c is fixedly connected to the limiting plate 161a, and the limiting plate 161a abuts against the user's head.

[0133] The first limiting member 162 includes a first limiting rod 162a and a first spring 162b.

[0134] The first limiting rod 162a is fixedly disposed on the first bracket 151 , and the first limiting rod 162a is slidably connected to the matching block 161b .

[0135] The first spring 162 b is sleeved on the first limiting rod 162 a , one end of the first spring 162 b is fixedly connected to the matching block 161 b , and the other end of the first spring 162 b is fixedly connected to the first bracket 151 .

[0136] The second limiting member 163 includes a first slide plate 163a, a second limiting rod 163b, a third limiting rod 163c, a second spring 163d and a third spring 163e.

[0137] The first slide plate 163 a is slidably disposed on the first bracket 151 .

[0138] The second limiting rod 163b is disposed on one side of the first limiting rod 162a. One end of the second limiting rod 163b is fixedly connected to the first slide plate 163a, and the other end of the second limiting rod 163b is inserted into the limiting plate 161a.

[0139] The third limiting rod 163c is disposed on the other side of the first limiting rod 162a. One end of the third limiting rod 163c is fixedly connected to the first slide plate 163a, and the other end of the third limiting rod 163c is inserted into the limiting plate 161a.

[0140] The second spring 163d is sleeved on the second limiting rod 163b. One end of the second spring 163d is fixedly connected to the first slide plate 163a, and the other end of the second spring 163d is fixedly connected to the limiting plate 161a.

[0141] The third spring 163e is sleeved on the third limiting rod 163c. One end of the third spring 163e is fixedly connected to the first slide plate 163a, and the other end of the third spring 163e is fixedly connected to the limiting plate 161a.

[0142] In this embodiment, when a user begins wearing a hearing aid capable of vagus nerve stimulation, the support assembly 15 compresses the user's head, causing the contact plate 161c to drive the limiting plate 161a to slide from the first slot 164a to the second slot 164b. During this process, the mating block 161b slides relative to the limiting plate 161a, and the limiting plate 161a compresses the second spring 163d and the third spring 163e, thereby further exerting a compressive force on the user's head. As the limiting plate 161a continues to move, driving the first rotating plate 24 to close the third slot 164c and move past the first rotating plate 24, the first rotating plate 24 returns to its original position. At this point, the support assembly 15 is stably clamped to the user's head.

[0143] When the user needs to change the contact position of the contact plate 161c and the head, the first hanging head 151b and the second hanging head 152b need to be stretched. At this time, the limiting plate 161a is driven to slide along the second groove 164b under the elastic force of the second spring 163d and the third spring 163e, and when the limiting plate 161a encounters the first rotating plate 24, the moving direction is changed, at this time, the limiting plate 161a slides along the third groove 164c, at this time, the position of the limiting plate 161a in the plumb direction changes and synchronously drives the contact plate 161c to change. And the matching block 161b will also slide relative to the limiting plate 161a. When the limiting plate 161a moves into the first groove 164a again, it will stably abut with the second rotating plate 25 under the elastic force of the first spring 162b. Then release the first hanging head 151b and the second hanging head 152b, the limiting plate 161a will repeatedly perform the above-mentioned movement and then press the head of the user again to provide stable clamping.

[0144] When the limiting plate 161a moves from the top of the first groove 164a to the bottom of the first groove 164a, it only needs to push the contact plate 161c to move vertically upward along the first groove 164a to the top of the second rotating plate 25 at the top.
