Description

Wireless wearable neurostimulation device

[0001] The present invention relates to a device for stimulating a nerve, and more particularly, to a nerve stimulation device developed to be easy to wear and use for applying electrical stimulation, etc. to nerves located around the ear, including the vagus nerve.

[0002]

[0003] The vagus nerve is one of the cranial nerves and is the tenth cranial nerve. It emerges from the brain and branches across the face, chest, and abdomen. As a mixed nerve containing parasympathetic fibers, it regulates the parasympathetic nervous system, which affects the heart, lungs, and digestive tract. It is the longest and most complex of the twelve pairs of cranial nerves, containing both sensory and motor fibers.

[0004] Vagus nerve stimulation devices for the treatment of epilepsy and depression have reportedly been approved by the U.S. Food and Drug Administration (FDA). These devices target the cervical branch of the vagus nerve. However, this cervical branch electrical stimulation procedure involves making a direct incision in the skin to expose the cervical branch of the vagus nerve. This procedure involves wrapping an electrical coil around the cervical branch and implanting a microchip, making it inappropriate for self-treatment by the general public.

[0005] Meanwhile, the human ear is a major pathway for the vagus nerve, and because the nerve is located close to the skin, it is considered a suitable site for external electrical stimulation. In Oriental medicine, acupuncture is used to treat diseases. Since the ear is where the auricular branch of the vagus nerve is distributed, stimulation of the vagus nerve can be considered a therapeutic approach. However, the use of acupuncture poses a challenge for the general public.

[0006] Furthermore, various nerves are located in and around the ear, and although technology has been developed to apply electrical stimulation by contacting the ear or around the ear with electrodes, it has the disadvantage of low utility due to the inconvenience of wearing and using.

[0007]

[0008] The present invention is intended to solve the problems of the prior art described above, and its purpose is to provide a nerve stimulation device in which electrodes are arranged so as to be convenient to wear and use while easily stimulating nerves located in the ear.

[0009]

[0010] In order to achieve the above object, the wireless wearable neurostimulation device according to the present invention is a neurostimulation device worn on a user's ear, comprising: an electrode part including one or more electrodes that contact the ear; a body part on which the electrode part is installed and which is positioned on the outside of the user's ear when worn; and a hook part connected to the body part and which is hooked to the user's ear pinna when worn to fix the device, wherein the hook part comprises: a first member located in front of the auricle and having a connection part connected to the body part; a second member extending rearward from the first member and including a soft material part at least in a portion that contacts the user's ear and is made of a soft material; and a third member extending rearward from the second member and positioned behind the auricle and including a power supply part for supplying power to the device.

[0011] It is preferable that the third member be detachable from the device, and the third member and the second member are coupled to each other, and the second member can be configured to be detachable from the first member.

[0012] The above connecting portion preferably includes an adjustment rod that can adjust the gap between the body portion and the first member, and can be configured to rotate the body portion using the adjustment rod as a rotation axis.

[0013] The electrode part is detachable from the body part, and it is preferable that the electrode part includes a first electrode that contacts the user's external auditory canal, a second electrode that contacts a part of the user's auricle, and a base body to which the first electrode and the second electrode are connected, and the base body is detachable from the body part.

[0014] At this time, the electrode part can be configured in a customized manner in which the arrangement of the first electrode and the second electrode is adjusted to fit the shape of the user's ear.

[0015] In addition, a light-emitting device may be installed on the base body, at least a part of the base body may be made of a light-transmitting material, and the light-emitting device may be installed so that light is transmitted through the light-transmitting material.

[0016] A light-emitting device may be installed in the second member, and the flexible material portion may be a light-transmitting material, and the light-emitting device may be installed so that light is transmitted through the flexible material portion.

[0017] The above power supply may be a secondary battery.

[0018]

[0019] The present invention, configured as described above, has the effect of improving the wearing comfort and increasing the usability of the nerve stimulation device by configuring the nerve stimulation device to be worn by hanging it on the user's ear.

[0020] At this time, the hanging part for hanging on the user's ear is divided into three parts, and the power supply is positioned behind the user's ear, thereby distributing the weight of the device, thereby improving the wearing comfort.

[0021] In addition, by configuring the third member of the hanger where the power supply is located to be replaceable, only the part containing the power supply can be replaced and used, so not only can the service life of the entire device be extended, but also it is advantageous for cleaning and disinfection, and various power supply structures can be applied by replacing the third member, and furthermore, it can be developed by combining a biosensing module with the third member in addition to the power supply structure. It has the effect of changing the usage form and design by combining a neckband or headband, etc., and since various types of biosensing modules with different sensing targets can be replaced and used, it can also function as a kind of platform for biosensing devices.

[0022] Furthermore, by configuring the electrode part where the electrode is formed to be detachable from the body part, not only is the management of the electrode easy, but there is also the effect of being able to replace and use a customized electrode part in which the position of the electrode is manufactured to suit the user.

[0030]

[0031] An embodiment of the present invention is described in detail with reference to the attached drawings.

[0032] However, the embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The shapes and sizes of elements in the drawings may be exaggerated for clearer explanation, and elements indicated by the same symbols in the drawings are the same elements.

[0033] Throughout the specification, when a part is said to be "connected" to another part, this includes not only the cases where it is "directly connected" but also the cases where it is "electrically connected" with another element in between. Furthermore, when a part is said to "include" or "comprise" a component, this does not mean that it excludes other components, but rather that it can include or comprise other components, unless otherwise specifically stated.

[0034] Additionally, terms such as "first," "second," etc. are intended to distinguish one component from another and should not be construed as limiting the scope of the rights. For example, the first component may be referred to as the second component, and similarly, the second component may also be referred to as the first component.

[0035] FIG. 1 is a drawing for explaining the configuration of a wireless wearable neurostimulation device according to one embodiment of the present invention, and FIG. 2 is a drawing for explaining the coupling structure of an electrode portion in a wireless wearable neurostimulation device according to one embodiment of the present invention.

[0036] The wireless wearable neurostimulation device of the present invention includes an electrode part (100), a body part (200), and a hanging part (300).

[0037] The electrode unit (100) includes at least one electrode (110) that contacts the user's ear and applies electrical stimulation to the vagus nerve of the ear, and preferably, two or more electrodes may be included. The following description assumes a situation in which the vagus nerve, a representative nerve located in the ear, is stimulated, but stimulation of the vagus nerve is not limited to stimulating the vagus nerve alone, and nerves passing through the ear and around the ear, including the vagus nerve, may be stimulated.

[0038] The vagus nerve passes through the external auditory canal and the cymba concha in the human ear. The helicis crus, a cartilaginous structure extending from the auricle, runs horizontally, separating the cavum concha, the opening of the external auditory canal, from the cymba concha.

[0039] In this embodiment, a first electrode (111) inserted into the external auditory canal and in contact with the second electrode (112) in contact with the auricle is included. Specifically, the second electrode (112) is configured to contact the conchae located in the concave portion above the otic ring. At this time, the first electrode (111) inserted into the external auditory canal is configured to transmit sound through the external auditory canal, and although the sound generating device of the earphone may be formed in the electrode portion (100), the sound generating device is installed in the body portion (200) and a structure is applied in which sound can be transmitted through the electrode portion (100).

[0040] In addition, in this embodiment, two electrodes are connected to the base body (120), and the base body (120) is configured to be detachable from the body part (200). In this way, by configuring the electrode part (100) to be detachable from the body part (200), not only can only the electrode part (100) be separated and stored or managed, but only the electrode part (100) can be replaced and used.

[0041] In the case where only the electrode unit (100) is separated and stored or managed, the electrodes that come into contact with the user's body can be cleaned and disinfected to ensure hygienic management. The entire wireless wearable neurostimulation device of the present embodiment can be stored in a separate cradle, and the parts that come into contact with the human body can be disinfected using an ultraviolet lamp or the like installed in the cradle. In this case, since only the electrode unit (100) is configured to be separated, cleaning and disinfection of the electrodes become easier, which has the advantage of enabling more hygienic management of the device.

[0042] In addition, since the electrode part (100) that is installed with electrodes that frequently come into contact with the human body during use and thus frequently break down and have a short lifespan is replaced, there is an advantage in that there is no need to replace the entire device due to a break down or durability issue in the electrodes. In addition, since the shape of each person's ear is different, a structure equipped with multiple electrodes may require customized electrode placement for each user, and while in the past, multiple devices had to be equipped depending on the user, in this embodiment, since the electrode part (100) can be replaced, there is an effect in that multiple users having electrode parts including a custom-made electrode structure can use one device by changing only the electrode parts.

[0043] FIG. 3 is a drawing for explaining a structure for attaching and detaching an electrode unit to a body unit in a wireless wearable neurostimulation device according to one embodiment of the present invention.

[0044] The structure for attaching and detaching the electrode part (100) to the body part (200) can be applied in various structures, and in this embodiment, the magnetic force of the magnet installed on one or both of the electrode part (100) and the body part (200) is used. In this embodiment, the electrode part (100) may be configured to transmit electricity for electrical stimulation to the electrode and transmit sound through the first electrode (111) inserted into the external auditory canal. To this end, the electrode part (100) must be precisely attached and detached at a specific position of the body part (200) where a terminal (210) for electrical transmission and an acoustic hole (220) for sound transmission are formed. In the case where the magnetic force between the magnet (122) installed on the base body (120) and the magnet (230) installed at a corresponding position is used, it is easy for the user to align the electrode part (100) at an accurate position with little force.

[0045] In addition, the mechanical coupling structure can be applied alone or together with a magnetically detachable structure, and in this embodiment, the fitting coupling is applied together to increase the coupling force between the electrode part (100) and the body part (200). Specifically, a concave indentation (240) is formed at the coupling position of the body part (200), and a corresponding protrusion (124) is formed on the base body (120) of the electrode part (100), so that the protrusion (124) is inserted into the indentation (240) when the electrode part (100) is coupled to the body part (200). At this time, in the illustrated embodiment, the sizes of the protrusion (124) and the indentation (240) are adjusted to an extent that separation is possible when a predetermined force is applied, and in another method, the degree to which the protrusion protrudes can be adjusted using an elastic device or an adjustment button, so that the protrusion does not protrude during the attachment / detachment process but only in the attached state. The protrusion (124) may be formed over the entire surface of the base body (120) or may be formed only on a portion thereof, and the indentation (240) is formed to correspond to the protrusion (124).

[0046] The body part (200) has a structure in which the electrode part (100) can be attached or detached, and is located on the outside of the user's ear when worn.

[0047] Since the present embodiment is configured to allow the electrode unit (100) to be detachable and to be used by exchanging and replacing the electrode unit (100), the components included in the electrode unit (100) are minimized to reduce weight and manufacturing cost, and the components for the operation of the vagus nerve stimulation device are installed in the body unit (200). For example, a driver and a stimulus generating device for the operation of the vagus nerve stimulation device may be installed in the body unit (200), and the driver and stimulus generating device for the operation of the vagus nerve stimulation device may be modified or applied as they are to the components for vagus nerve stimulation or other nerve and muscle stimulation within a range that does not impair the characteristics of the present invention.

[0048] In this embodiment, a terminal (210) for transmitting electricity for electrical stimulation to a detachable electrode portion (100) and an acoustic hole (220) for transmitting sound through a first electrode (111) inserted into the external auditory canal are formed in the body portion (200). In addition, the main functions of the body portion (200) have been described in the process of explaining the configuration of the electrode portion (100) above, so a detailed description thereof will be omitted.

[0049] The hanging part (300) is a part that hangs the device on the user's earlobe when worn, and is composed of a first member (310), a second member (320), and a third member (330).

[0050] The first member (310) is located in front of the earlobe when worn and is connected to the body part (200) through a connecting part (312).

[0051] The connecting portion (312) is configured to perform the function of connecting the hanging portion (300) including the first member (310) and the body portion (200) while simultaneously adjusting the arrangement of the hanging portion (300) and the body portion (200) according to the user.

[0052] FIG. 4 is a drawing for explaining a structure for connecting a body part and a first member in a wireless wearable neurostimulation device according to one embodiment of the present invention.

[0053] First, the connecting part (312) includes an adjustment rod (316) that can adjust the gap between the first member (310) and the body part (200) by adjusting the exposed length. The adjustment rod (316) has a structure in which all or part of it is stored in one or both of the body part (200) or the first member (310), and the gap between the first member (310) and the body part (200) can be adjusted by adjusting the length of exposure of the stored part. Since people's ears are different in shape and size, when the device is worn by hanging the earring part (300) on the ear, the position of the body part (200) connected to the earring part (300) may vary from person to person, and when the gap between the body part (200) and the hanging part (300) is fixed, there is a problem in that it is difficult for the electrode of the electrode part (100) to make contact at an accurate position. The present invention is configured to allow the gap between the first member (310) and the body part (200) to be adjusted so that various users can use it by adjusting the gap according to their body type.

[0054] Furthermore, by configuring the body part (200) to be able to rotate with the adjustment rod (316) as the rotation axis, the angle of the body part (200) with respect to the first member (310) can be adjusted. Not only the size and shape of the ears but also the angle of the auricle and external auditory canal differ from person to person, and the present invention is configured to be able to adjust the angle at which the first member (310) and the body part (200) are arranged, so that various users can use it by adjusting the angle according to their body shape.

[0055] When adjusting the position of the body part (200) to suit the user's body type, the length and angle of the adjustment rod (316) can be freely adjusted, but after adjustment, a fixing means (not shown) is provided to fix the length and angle of the adjustment rod (316), and the user can adjust the fixing means to operate after releasing the fixing means through the adjustment button (314) to perform the adjustment.

[0056] Meanwhile, the size of the body part (200) can be reduced by installing components such as a wireless receiving device in the first member (310). In addition, the size and weight of the body part (200) can be reduced by distributing the components necessary for the operation of the vagus nerve stimulation device in the first member (310) and the body part (200).

[0057] The second member (320) extends backward from the first member (310) and is a part that is placed on the user's ear when worn.

[0058] The second member (320) is a part that is placed on the ear, and since it is the part where the weight of the vagus nerve stimulation device is applied to the ear, at least the part that comes into contact with the user's ear is made of a soft material. In the present embodiment, the entire outer case of the second member (320) is made of a soft material, but if necessary, only the lower part, which is the part that comes into contact with the user's ear, may be made of a soft material.

[0059] Additional structures and features applied to the second member (320) are described together with the third member (330).

[0060] The third member (330) extends backward from the second member (320) and is a part located behind the user's ear when worn.

[0061] The vagus nerve stimulation device of the present invention uses electricity for electrical stimulation, etc., and supplies the power required for the vagus nerve stimulation device through the third member (330). For example, a power supply line connected to an external power supply device may be connected to the third member, or, as in the present embodiment, a power supply unit composed of a secondary battery may be included inside the third member (330). In this case, a power supply configuration, such as a power line for transmitting power from the power supply unit installed in the third member (330) to the first member (310) and the body (200), is installed in the second member (320).

[0062] The present invention distributes the weight of the device evenly between the front and back of the auricle by installing a power supply line or power unit for power supply in a third member (330) located at the back of the auricle, thereby distributing the weight with the body part (200) connected through the first member (310) located at the front of the auricle. In addition, when the power supply line is connected to the back of the auricle, user discomfort can be minimized.

[0063] FIG. 5 is a drawing for explaining a structure for separating a power supply unit in a wireless wearable neurostimulation device according to one embodiment of the present invention.

[0064] The present invention is characterized in that the third member (330) including the power supply unit is configured to be detachable from the device. At this time, since the present embodiment installs a secondary battery as a power supply unit for supplying power to the vagus nerve stimulation device in the third member (330), the third member (330) can be detached and charged separately or used by exchanging it with an additionally provided third member (330). Through this, the usage time of the device can be increased, and even when the power supply unit needs to be replaced due to a decrease in the lifespan of the secondary battery, only the part including the power supply unit can be replaced without replacing the entire device.

[0065] The configuration that allows the third member (330) to be separated is not particularly limited, and the second member (320) and the first member (310) may be configured to be fixed and the third member (330) to be detachable from the second member, or the third member (330) and the second member (320) may be configured to be fixed and the second member (320) to be detachable from the first member (310). In the present embodiment, the second member (320) is configured to be detachable from the first member (310), and the second member (320) can be coupled to and detached from the first member (310) through a connector (322) that can transmit power.

[0066] Meanwhile, it is also possible to apply third members having different shapes and functions by separating the third member (330). In the illustrated embodiment, the vagus nerve stimulation devices worn on both ears are separate from each other, but the third member can be manufactured in the form of a neckband, and the structure can be modified to combine both devices into one third member, or the headband can be connected, and other structures and designs can be applied. In addition, the third member (330) can be replaced and used with newly developed or advanced technical features, and for example, it can be configured to be combined with a biosensing module. The biosensing module is a modularized device having a biosensing function, and means a module that can be replaced or added to the third member of the present embodiment, and the remaining components, except for the components essential for biosensing, can use other components included in the nerve stimulation device of the present embodiment. Since biosensing devices need to be stably attached to the human body while still capable of sensing, currently, various types of biosensing devices with different sensing targets are sold individually, each with its own components for attachment to the human body. This increases the manufacturing cost of biosensing devices, lowers users' willingness to purchase them, and makes them inconvenient to use, thus hindering the usability of biosensing devices. Since the neurostimulation device of the present embodiment is a wireless wearable device, it can be stably attached to the human body while still capable of sensing when components capable of biosensing are added or replaced. Furthermore, modularization of the biosensing device allows for the interchangeability of various types of biosensing modules with different sensing targets, which has the effect of greatly increasing usability. In this way, the neurostimulation device of the present embodiment can function as a kind of platform for biosensing devices that enable the interchangeability of various biosensing modules.

[0067] Furthermore, the wireless wearable neurostimulation device of the present invention may include various display units that can inform the user of the status of the device by displaying it with light during the process of using and managing the device, and a light-emitting device may be installed for this purpose.

[0068] First, a light-emitting device is installed on the base body (120) of the electrode part (100) to indicate whether the electrode part (100) is completely connected to the correct position of the body part (200), and a display part (not shown) made of a light-transmitting material that transmits light from the light-emitting device is positioned on the base body (120). The display part of the base body (120) may be formed of a light-transmitting material on the entire surface exposed to the outside while attached to the body part (200), or the light-transmitting material may be exposed only on a portion thereof.

[0069] And, a light-emitting device may be installed in the second member (320) to display the connection status of the power supply included in the third member (330) and the remaining charge of the secondary battery. In this embodiment, the flexible material part is applied as a light-transmitting flexible material so that the light of the light-emitting device is transmitted through the flexible material part.

[0070] In addition, the light emitting device of the second member (320) and the light emitting device of the base body (120) can be applied separately or simultaneously for the purpose of indicating whether the device is in use, the use status, and whether it is wirelessly connected.

[0071] In the embodiment of the present invention discussed above, the position and angle of the body portion (200) can be adjusted through the adjustment rod (316) applied to the connecting portion (312) connecting the body portion (200) and the first member (310), thereby allowing the electrode (110) to contact a position suitable for applying an electric stimulus to the user. However, although it is easy to adjust the position of the first electrode (111) inserted into the external auditory canal through position adjustment using the adjustment rod (316), the second electrode (112) configured to contact the auricle may not be easily contacted by adjusting only the adjustment rod (316) depending on the shape of the user's auricle, etc.

[0072] FIG. 6 is a drawing for explaining the installation structure of a second electrode in a wireless wearable neurostimulation device according to another embodiment of the present invention.

[0073] In order to solve the above problem, in the illustrated embodiment, a structure was applied in which the position and angle of the second electrode (112) can be changed according to the shape of the user's ear.

[0074] First, in the embodiment shown on the left, a spherical joint (1121) and a connecting member (1122) are applied as a structure in which the second electrode (112) is installed by protruding from the base body (120). The spherical joint (1121) is positioned by being inserted into the base body (120), and the second electrode (112) is positioned at the end of the connecting member (1122) extended from the spherical joint (1121). By applying a structure in which the second electrode (112) is positioned at the end of the connecting member (1122) extended from the spherical joint (1121), the position of the second electrode (112) can be changed according to the movement of the spherical joint (1121) by the pressure applied to the second electrode (112).

[0075] Next, in the embodiment shown on the right, an elastic connecting portion (1123) is applied as a structure in which the second electrode (112) is installed by protruding from the base body (120). The elastic connecting portion (1123) is a structure that connects the base body (120) and the second electrode (112), and is made of an elastic material so that the shape can be changed within a predetermined range depending on the pressure applied to the second electrode (112), thereby changing the position of the second electrode (112).

[0076] In this structure, the second electrode (112) can come into perfect contact with the user's auricle as the ball-and-socket joint (1121) and elastic connecting portion (1123) are deformed according to the shape of the user's auricle.

[0077] In this way, since the contact between the first electrode (111) and / or the second electrode (112) may be problematic, a configuration for checking the contact between the electrodes (110) may be additionally provided.

[0078] In order to confirm the contact of the electrode (110), a touch sensor, a pressure sensor, a contact sensor, etc. can be applied, and a plurality of sensors can be installed, and the number of sensors that come into contact with the user's skin among all sensors can be checked, and if it is determined that the number of sensors that come into contact is less than a predetermined number, a notification can be generated to the user or the electrical stimulation can be set to be stopped. At this time, in the case of a sensor that can be applied through the electrode (110), such as a touch sensor or a contact sensor, the contact portion where the electrode (110) comes into contact with the skin can be divided into multiple parts and a plurality of sensors can be applied.

[0079] Furthermore, in order to improve and enhance the contact characteristics of the electrode (110), a material whose external shape can be deformed according to the user's skin surface can be applied to the portion where the electrode (110) is installed. For example, if a material with a more free surface shape deformation, such as a solid gel, is applied rather than a simple flexible material, its external shape can be deformed according to the curved surface of the human body, thereby increasing the area where the electrode (110) can come into contact with the skin.

[0080] The present invention has been described above through preferred embodiments. However, the above-described embodiments are merely illustrative of the technical idea of ​​the present invention. Those skilled in the art will understand that various changes may be made without departing from the technical idea of ​​the present invention. Therefore, the scope of protection of the present invention should be interpreted not by specific embodiments, but by the matters described in the claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included within the scope of the rights of the present invention.
