Description

Technical Field

[0001] The utility model relates to an auricular vagus nerve stimulator. Background Art

[0002] As is well known, among the twelve cranial nerves, the vagus nerve is considered to be a unique and simple visceral nerve, with the most extensive distribution in the body, connecting and interacting with the nervous system of our body. When it is stimulated, it will feedback signals to the central nervous system such as the hippocampus and cingulate gyrus, making the parasympathetic nerve excited and the sympathetic nerve inhibited, thereby affecting the physical and mental state of the human body and relaxing it.

[0003] Vagus nerve stimulation is a form of neuromodulation, which is widely used in the medical field. With the development of technology, it has gradually been extended to the application in the fields of life such as stress relief and sleep assistance. The auricular concha area of the ear is a region where the external auditory meatus vagus nerve is richly distributed. In recent years, it has been found that electrical stimulation of the innervated area of the superficial vagus nerve may also produce effects similar to those of the vagus nerve. Accordingly, the vagus nerve stimulation technology through the auricular concha area has emerged, and correspondingly, ear-hung vagus nerve stimulation devices have also appeared.

[0004] For example, the Chinese invention patent application with the publication number CN101797415A (application number 201010111662.8) discloses a sleep assistance device, which proposes a structure of a head-mounted earphone. In this sleep assistance device, a push rod fluff brush is provided to stimulate the vagus nerve of the human ear canal to achieve the effect of assisting sleep. When using this structure of the sleep assistance device, it is easy to slide off. To ensure that it does not slide off after wearing, a greater clamping force is required, which will instead affect the user's sleep. In addition, the electrostimulation effect is different for different people. Within the range of low voltage safe for the human body, too large a human body resistance will lead to poor electrostimulation effect and poor sleep assistance effect. And the dirt in the ear is the main reason for the too large human body resistance. The existing devices for auricular vagus nerve stimulation cannot clean the dirt in the user's ear, and thus there will be a problem that the electrostimulation effect is very limited. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an auricular vagus nerve stimulator that can clean the user's ear hole and thus improve the effect of vagus nerve electrostimulation in view of the above-mentioned prior art.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: An auricular vagus nerve stimulator includes a control module, an air pump, and a stimulation member that can be worn in the ear. The stimulation member includes a base body and a first electrode head disposed on the base body. The control module is electrically connected to the air pump and the first electrode head. It is characterized in that: it further includes a second electrode head disposed on the base body. The second electrode head includes an action head with a cavity inside and a first airbag disposed in the cavity. The action head is electrically conductive and is electrically connected to the control module. A plurality of through holes are formed in the action head. The first airbag is connected to the air pump through air.

[0007] Preferably, an air flow channel is provided in the base body. The inlet of the air flow channel is connected to the air pump through air, and the first airbag is connected to the outlet of the air flow channel.

[0008] In order to improve the wearing comfort, the first electrode head is in the shape of a fish fin and is used to match and place at the position of the cymba conchae in the ear, and the second electrode head is in the shape of a cylinder and is matched and placed at the position of the ear hole in the ear.

[0009] In order to improve the cleaning effect on the cleaning position in the ear hole, a driving mechanism is further provided on the base body. The action head is connected to the driving end of the driving mechanism and vibrates based on the driving of the driving mechanism.

[0010] Preferably, a plurality of through holes are arranged along the circumferential wall of the action head.

[0011] Optionally, the control module is arranged in the base body.

[0012] Preferably, it further includes an eye mask body that can cover the eyes and a fixing band connected between both ends of the eye mask body. The control module and the air pump are arranged in the eye mask body.

[0013] In order to improve the comfort after wearing, a second airbag is provided on the inner side of the eye mask body corresponding to the eye area. The second airbag is connected to the air pump through air.

And the structure of the second electrode head is specially designed. The second electrode head includes an acting head and an airbag disposed therein, and through holes are also provided on the acting head. Based on this structure, before performing vagus nerve stimulation work, the airbag can be inflated, so that a part of the airbag protrudes from the surface of the acting head through the through holes, and then the airbag is used to clean the position to be stimulated in the ear canal. Then after the airbag releases the gas, the acting head of the second electrode head and the first electrode head can normally perform vagus nerve stimulation. The skin impedance after cleaning is lower. Furthermore, when performing electrical stimulation work, the vagus nerve stimulation effect is better, thereby enhancing the sleep aid effect.

[0020] The present utility model will be further described in detail below with reference to the embodiments in the drawings.

[0021] As Figures 1 to 3 shown, the auricular vagus nerve stimulator in this embodiment includes a control module, an air pump, and a stimulating member 100 that can be worn in the ear. The control module is electrically connected to the air pump and the stimulating member 100, respectively, so as to control the air pump and the stimulating member 100 to work.

[0022] The stimulation component 100 can be used relatively independently, such as being applied to the user's ear in a similar way to wireless earphones. Based on this application, the control module and the air pump can both be arranged in the base body 1. The air pump is relatively large in volume and is likely to cause wearing pressure on the ear. To further improve the wearing comfort and stability and facilitate the miniaturization design of the stimulation component 100, the auricular vagus nerve stimulator in this embodiment further includes an eye mask body 5 that can cover the eyes and a fixing strap 6 connected between the two ends of the eye mask body 5. The control module and the air pump can be arranged in the eye mask body 5. The user wears the eye mask body 5 on the head by using the fixing strap 6, so that the eye mask body 5 covers the eyes and blocks external light, thereby improving the sleep aid effect. At the same time, according to needs, various modules beneficial to sleep aid can also be arranged on the eye mask body 5, such as a massage module that can massage around the eyes. To improve the comfort after the eye mask body 5 covers the user's eyes, a second airbag 7 is arranged on the inner side of the eye mask body 5 corresponding to the eye area. The second airbag 7 is in air communication with the air pump. The second airbag 7 is flat. After the user wears the eye mask body 5 on the head, the control module controls the air pump to inflate the second airbag 7, so that a flexible contact is achieved between the eye mask body 5 and the user's eyes.

[0023] To ensure the balance of the auricular vagus nerve stimulation for both ears, a stimulation component 100 is flexibly connected to each end of the eye mask body 5. The stimulation component 100 is flexibly connected to the eye mask body 5 through the electrical connection line between the following base body 1 and the control module.

[0024] The stimulation component 100 includes a base body 1 and a first electrode head 2 and a second electrode head 3 arranged on the base body 1. The first electrode head 2 and the second electrode head 3 are respectively electrically connected to the control module. To improve the wearing comfort, the first electrode head 2 is in the shape of a fish fin and is used to match and place in the cymba conchae position in the ear. The fish fin-shaped first electrode head 2 can ensure the stability of its assembly in the cymba conchae position in the ear. The second electrode head 3 is in the shape of a cylinder and is matched and placed in the ear hole position in the ear. The cylindrical second electrode head 3 can better match the shape of the ear hole.

[0025] However, there is usually dirt in the human ear hole, which will increase the skin impedance and correspondingly reduce the stimulation effect of the auricular vagus nerve stimulation. The auricular vagus nerve stimulator in this embodiment can use the second electrode head 3 to clean the dirt in the ear hole, reduce the skin impedance, and thus improve the stimulation effect of the auricular vagus nerve stimulation.

[0026] Specifically, the second electrode head 3 includes a working head 31 with a cavity inside and a first airbag 32 disposed in the cavity. The working head 31 is electrically conductive and is electrically connected to the control module. The working head 31 in the second electrode head 3, based on the power supply of the control module, cooperates with the first electrode head 2 to act as two electrodes for performing vagus nerve electrical stimulation on the ear. A plurality of through holes 311 are formed in the working head 31, and a plurality of through holes 311 are arranged along the peripheral wall of the working head 31. The first airbag 32 is connected to the air pump through a ventilation connection. For the convenience of structural arrangement, an air flow channel is provided in the base body 1. The inlet of the air flow channel is connected to the air pump through a ventilation connection, and the first airbag 32 is connected to the outlet of the air flow channel.

[0027] The first airbag 32 is made of a flexible material and can expand based on the inflation of the air pump and contract based on the suction of the air pump. When the air pump inflates the first airbag 32, the part of the first airbag 32 corresponding to the through holes 311 protrudes out of the through holes 311 and is in close contact with the skin of the user's ear hole, enabling the cleaning of the skin inside the ear hole. When the first airbag 32 is sucked, the first airbag 32 contracts and is located inside the working head 31. In order to improve the cleaning effect, the air pump can be controlled to inflate and suck the first airbag 32 cyclically, thereby achieving a better cleaning effect.

[0028] However, in order to further improve the cleaning effect of the first airbag 32 on the skin inside the ear hole, a driving mechanism 4 is further provided on the base body 1. The working head 31 is connected to the driving end of the driving mechanism 4 and vibrates based on the driving of the driving mechanism 4. When cleaning the ear hole in this way, first inflate the first airbag 32 so that a part of the first airbag 32 protrudes out of the outer surface of the working head 31 from the through holes 311, and then drive the working head 31 based on the driving mechanism 4 to drive these protruding parts to rub the skin inside the user's ear hole, thereby achieving the cleaning of the skin inside the ear hole.

[0029] For the convenience of cleaning the first airbag 32, both the first airbag 32 and the working head 31 can be connected to the base body 1 in a detachable connection manner. In this way, the dirt on the first airbag 32 can be cleaned by disassembling the working head 31 and the first airbag 32.

[0030] When the auricular vagus nerve stimulator is in use, the skin inside the ear hole can be first cleaned by using the second electrode head 3 to reduce the skin impedance, and then the vagus nerve electrical stimulation work can be carried out to improve the vagus nerve electrical stimulation effect.

[0031] In the auricular vagus nerve stimulator of the present utility model, the stimulating member 100 can be independently and adaptively installed in the ear, improving the stability and comfort of the installation in the ear. Moreover, the structure of the second electrode head 3 is specially designed. The second electrode head 3 includes an acting head 31 and an airbag disposed therein, and a through hole 311 is further formed in the acting head 31. Based on this structure, before performing the vagus nerve stimulation operation, the airbag can be inflated so that a part of the airbag protrudes from the surface of the acting head 31 through the through hole 311, and then the airbag is used to clean the position to be stimulated in the ear canal. Then, after the airbag releases the gas, the acting head 31 of the second electrode head 3 cooperates with the first electrode head 2 to normally perform the vagus nerve stimulation. The skin impedance after cleaning is lower, and thus when performing the electrical stimulation operation, the vagus nerve stimulation effect is better, thereby enhancing the sleep aid effect.
