Description

Fixed band for brainwave sensor and brainwave sensor using the same

[0001] The present invention relates to a fixed band for an EEG sensor and an EEG sensor using the same, and more particularly, to a fixed band for an EEG sensor for fixing an electrode for collecting EEG signals of an animal, including a human, to the head and an EEG sensor using the same.

[0002] In general, brain waves are caused by the electrical activity of nerve cells that make up the brain, and can be measured in the form of electrical signals through electrodes on the skin.

[0003] Since the brain wave measurement subject varies in shape, size, and curvature, the size of the EEG measurement device attached to the skin must be miniaturized to ensure stable skin contact between the electrodes. Maintaining a good seal and electrical connection are also crucial. Maintaining an appropriate distance between measurement channels is also crucial for EEG quality.

[0004] In special situations such as surgery, it is necessary to measure brain waves to determine the depth of anesthesia. In this case, the depth of anesthesia can be determined by measuring the brain waves of the surgical subject.

[0005] In particular, in the case of animals, there was a problem that the contact between the skin and the electrode was uneven because there was hair around the frontal lobe where brain waves were measured.

[0006] Additionally, since the animal's scalp is soft, even when the EEG measuring device is fixed using a fixation band, there was a problem in that the EEG measuring device's fixation location changed because the animal moved back and forth near the frontal lobe.

[0007] Therefore, there is a need for an EEG measurement device that can be simply and stably fixed to an animal's head while maintaining stable contact with the skin.

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention relates to a fixing band for an EEG sensor for fixing an electrode for collecting EEG signals of an animal, including a human, to the head, and to an EEG sensor using the same.

[0051] A fixing band for an EEG sensor according to a first embodiment of the present invention, as illustrated in FIGS. 1 to 4, is a flexible fixing member that is fixed to the forehead or frontal lobe of an animal, including a human, for measuring EEG of the animal, and is fixed to the head of the animal to collect EEG from the animal's skin. The fixing band (100) is made of a flexible material, such as a urethane film or non-woven fabric, so that it can be fixed in close contact with the head of the animal without irritating the animal's skin. This fixing band (100) is composed of a head fixing part (110), a connecting part (140), an ear fixing part (120), and a character pattern (130).

[0052] The head fixing member (110) is a fixing member that surrounds and fixes the animal's chin and head. It is formed in the shape of a long belt and is positioned and fixed to wrap around the animal's face. The head fixing member (110) is composed of a first head fixing member (111) and a second head fixing member (112).

[0053] The first head fixing member (111) may be extended to one side based on the connecting member (140) and may be positioned from the animal's forehead to the side of the face. A first detachable member (111a) may be provided at the front end of the first head fixing member (111). Here, the front means the direction opposite to the direction facing the animal's skin.

[0054] The second head fixing member (112) may be extended to the other side based on the connecting member (140) and may be arranged to contact the end of the first head fixing member (111) from the forehead of the animal, passing through the side of the face on the other side, the chin. A second detachable member (112a) may be provided at the middle of the front of the second head fixing member (112), a third detachable member (112b) may be provided at the front end, and a fourth detachable member (112c) may be provided at the rear end. Here, the rear side means the direction toward the animal's skin.

[0055] Accordingly, the first head fixing part (111) is formed shorter than the second head fixing part (112), and the head is wrapped around the animal on both sides based on the connecting part (140) to compress and surround the head, and each end is mutually connected and fixed on the side of the face.

[0056] At this time, the first detachable member (111a) on the front of the first head fixing member (111) and the fourth detachable member (112c) on the rear of the second head fixing member (112) can be fixed by being combined with each other. It is preferable that the first and fourth detachable members (111a, 112c) are formed of Velcro.

[0057] Although not shown in the drawing, the shape and length of the first and second head fixing members (111, 112) can be formed in various ways, and any shape is possible as long as it can be fixed around the head, and the first and fourth detachable members (111a, 112c) can be of any shape as long as they can be combined with each other.

[0058] The connecting member (140) is a connecting member that protrudes and extends from the middle of the length of the head fixing member (110) and connects the head fixing member (110) and the ear fixing member (120). It is preferable that the position where the connecting member (140) protrudes is the center of the animal's forehead.

[0059] The ear fixing member (120) is a fixing member that surrounds and fixes each ear of the animal, and is formed on one side and the other side of the connecting member (140) and is positioned and fixed to surround and fix each of the one and the other ears of the animal. The ear fixing member (120) is composed of a first ear fixing member (121) and a second ear fixing member (122).

[0060] The first ear fixing part (121) branches off from the end of the connecting part (140) and extends to one side to surround and secure one ear of the animal. A fifth detachable member (121a) may be provided at the rear end of the first ear fixing part (121). The first ear fixing part (121) surrounds one ear of the animal, and the fifth detachable member (121a) may be coupled to the third detachable member (112b). Specifically, in a state where the fourth detachable member (112c) at the rear of the second head fixing part (112) is coupled to the first detachable member (111a) at the front of the first head fixing part (111), the fifth detachable member (121a) at the rear of the first ear fixing part (121) is coupled to the third detachable member (112b) at the front of the second head fixing part (112).

[0061] The second ear fixing part (122) branches off from the end of the connecting part (140) and extends to the other side to surround and secure the other ear of the animal. A sixth detachable member (122a) may be provided at the rear end of the second ear fixing part (122). The second ear fixing part (122) surrounds the other ear of the animal, and the sixth detachable member (122a) may be coupled to the second detachable member (112a). Specifically, the sixth detachable member (122a) at the rear of the second ear fixing part (122) is coupled to the second detachable member (112a) disposed at the middle front of the second head fixing part (112).

[0062] Accordingly, the first ear fixing part (121) and the second ear fixing part (122) are formed to have the same length, branch off from the end of the connecting part (140) to both sides and wrap around each ear. Thereafter, the ends of the first and second ear fixing parts (121, 122) are fixed by being coupled to the detachable member of the head fixing part (110). It is preferable that the third and fifth detachable members (112b, 121a) and the second and sixth detachable members (112a, 122a) are formed of Velcro.

[0063] The ear fixing part (120) may have a groove (120a) formed concavely toward the connection part (140) between the first and second ear fixing parts (121, 122) branching out. This groove (120a) can be bent more flexibly when each of the first and second ear fixing parts (121, 122) bends to wrap around both ears, thereby improving adhesion to the skin.

[0064] Although not shown in the drawing, the shape and length of the ear fixing member (120) can be formed in various ways, and any shape is possible as long as it can be fixed around the ear. In addition, the third and fifth detachable members (112b, 121a) and the second and sixth detachable members (112a, 122a) can each have any shape as long as they can be coupled to each other.

[0065] Meanwhile, at least one of the detachable members that are connected to each other can be formed to have a length longer than the width. This allows the wrapping length to be adjusted to a predetermined length depending on the head circumference and ear circumference of the animal.

[0066] In the case of animals, the scalp is soft, so the electrode assembly (200) can move back and forth on the animal's head with only the head fixing part (110). Therefore, by forming the ear fixing part (120) to fix the ears together, the electrode assembly (200) can be stably fixed by the fixing band (100).

[0067] The character pattern (130) is a display member printed or displayed on the front of the fixed band (100), and guides the user by indicating the location of the electrode assembly placed on the center and back of the animal's forehead.

[0068] This allows the user to position the electrodes on the center of the animal's forehead without having to turn over the fixing band (100) to check the positions of the electrodes placed on the back of the fixing band (100), and to identify the positions of each electrode.

[0069] Hereinafter, a method for fixing and using the fixing band for the brainwave sensor of the present invention will be briefly described. As illustrated in Fig. 9, the user secures the head fixing part (110) around the head of the animal, and then secures the first and second ear fixing parts (121, 122) around each of the two ears. At this time, the center of the electrode assembly (200) (identifiable by the character pattern) is adjusted and secured so that it is positioned at the center of the animal's forehead.

[0070] The method of fixing and using the fixed band described above may be changed in some order depending on the user's convenience or situation.

[0071]

[0072] Below, a fixed band for an EEG sensor according to a second embodiment of the present invention will be described. Components having the same form or function as those in the first embodiment are designated by the same drawing reference numerals, and a description of the same components will be omitted.

[0073] The biosignal sensor according to the second embodiment of the present invention has a different shape of the ear fixing part (120) compared to the first embodiment, as shown in FIGS. 10 and 11.

[0074] The fixed band (100) is composed of a head fixing part (110) and an ear fixing part (120). The head fixing part (110) is the same as the first embodiment, and the ear fixing part (120) is composed of third and fourth ear fixing parts (123, 124).

[0075] The third ear fixing part (123) has an ear insertion port (133) formed on one side of the connecting part (140) into which one ear of the animal is inserted. One ear of the animal is inserted and fixed into the ear insertion port (133).

[0076] The fourth ear fixing part (124) has the same shape and function as the second ear fixing part (122) of the first embodiment.

[0077] The ear fixing part (120) may have a groove (120a) formed concavely toward the connection part (140) between the third and fourth ear fixing parts (123, 124) branching out. This groove (120a) can be bent more flexibly when each of the third and fourth ear fixing parts (123, 124) bends to wrap around both ears, thereby improving adhesion to the skin.

[0078] Accordingly, compared to the first embodiment, the action of fixing the first ear fixing part (121) to the first head fixing part (111) can be replaced with the action of inserting the ear into the ear insertion port (133). Specifically, the user inserts one ear into the ear insertion port (133), then fixes the head fixing part (110) so that it wraps around the animal's head and chin, and then fixes the fourth ear fixing part (124) by wrapping it around the other ear and connecting it to the head fixing part (110).

[0079] The method of fixing and using the fixed band described above may be changed in some order depending on the user's convenience or situation.

[0080]

[0081] Hereinafter, a brainwave sensor using a fixed band for a brainwave sensor corresponding to another aspect of the present invention will be described. The brainwave sensor relates to a brainwave sensor that senses brainwaves using the fixed band described above, and as illustrated in FIGS. 1 to 8, is largely composed of a fixed band (100), an electrode assembly (200), and a conductive material storage body (300). A description of the fixed band (100) described above will be omitted.

[0082] The electrode assembly (200) is an electrode assembly that is placed on a body part of an animal to collect brain wave signals of the animal and is connected to the back of a fixed band (100), and is composed of a sheet portion (210), an electrode portion (220), a wiring portion (230), an insulation portion (240), and a connection portion (250).

[0083] The sheet member (210) is a sheet member that is joined to the rear of the fixed band (100), and is preferably made of a flexible material such as urethane or non-woven fabric. This sheet member (210) can be joined to the fixed band (100) using double-sided tape or adhesive.

[0084] The electrode part (220) is configured on the rear side of the sheet part (210) and is an electrode member placed on a body part of an animal to collect the animal's bio-signals. In the embodiment, it is placed on the head fixing part (110) to be placed on the animal's forehead and is composed of a plurality of electrodes.

[0085] Multiple electrodes, including a ground electrode, a reference electrode, and a channel electrode, can be provided in at least three numbers to improve the quality of EEG signal collection. For example, the ground electrode is preferably placed at the center of the animal's forehead, and the reference electrode and channel electrode are preferably placed on either side of the ground electrode at equal distances from each other.

[0086] Meanwhile, the closer the electrode is to the frontal lobe, the better the quality of the collected brain wave signal. However, in the case of small animals, the forehead is narrow, so it is often difficult to position the electrode on the frontal lobe. Therefore, it is preferable to place the electrode unit (220) between the frontal lobe and the crown of the head.

[0087] The wiring unit (230) is a wiring member that electrically transmits brain wave signals collected from the electrode unit (220), and is composed of a plurality of wires, each of which is electrically connected to a plurality of electrodes. Each of the plurality of wires is formed so as not to overlap with each other.

[0088] It is preferable that the wiring section (230) be arranged in a direction in which it is drawn out from each of the plurality of electrodes toward the crown of the animal.

[0089] These electrode portions (220) and wiring portions (230) can be formed by printing silver or silver chloride ink on the sheet portion (210), and any material and shape is possible as long as biosignal collection and signal transmission are possible.

[0090] Meanwhile, although not shown in the drawing, the electrode and wiring portions may be placed on the rear of the fixed band without the sheet portion. For example, a method of directly printing the electrode and wiring portions on the rear of the fixed band may be used.

[0091] The insulating part (240) is an insulating material that wraps around the rear surface of the wiring part (230) to insulate the wiring part (230), and can prevent the wiring part (230) that passes between the electrode parts (220) or is extended toward the crown of the animal from causing a short circuit due to contact with the animal's skin, the user, external conductive materials, etc.

[0092] The connecting portion (250) is a connecting member that electrically connects and transmits biosignals received from multiple wires to the outside, and is electrically connected to the other end of each of the multiple wires. This connecting portion (250) is connected to external devices such as a signal amplifier or collector.

[0093] The conductive material storage body (300) is a conductive member that is coupled to the rear of the electrode assembly (200) and electrically connects the electrode assembly (200) and the animal's skin via the conductive material (301). The conductive material storage body (300) is composed of a main body (310), a storage body, and a partition wall (340), and includes the conductive material (301).

[0094] The main body (310) is a main body member that is coupled to the rear of the electrode assembly (200), and is arranged to include positions corresponding to a plurality of electrodes. In order to improve the contact area and fixing force with the electrode assembly (200), a portion of the main body may be formed to protrude in the direction of the animal's crown. The main body (310) may be composed of a material such as silicone rubber.

[0095] The storage unit is positioned at a position corresponding to the positions of the plurality of electrodes and has a plurality of internal spaces within the main body (310). A conductive material (301) is embedded in each of the plurality of internal spaces. The storage unit is made of an elastic material so that when elastic deformation occurs, the conductive material is discharged from the storage unit to the skin. The storage unit can be divided into a first storage unit (320), a second storage unit (330), and a third storage unit (350).

[0096] The first storage unit (320) is arranged on the front side of the main body unit (310), and has internal spaces formed at positions corresponding to the plurality of electrodes, and a conductive material (301) is embedded in each internal space. The conductive material embedded in each internal space electrically connects the skin of the animal and the electrode unit (220). In the case of animals, since the forehead area also has a lot of hair, it is difficult for the electrode unit (220) to be in direct contact with the animal's forehead, so the conductivity can be improved by using a conductive material.

[0097] Each of the plurality of first storage units (320) may be provided with a carrier (321) having a porous structure that absorbs and stores a conductive material in its internal space. The carrier (321) may be made of a sponge-like material to reduce evaporation of the conductive material and prevent the conductive material from being discharged through the second storage unit (330).

[0098] The second storage unit (330) is positioned so as to be in communication with the rear side of the first storage unit, thereby forming an internal space for discharging a conductive material onto the skin, and discharges the conductive material stored in each of the plurality of first storage units (320) to the rear side of the main body unit (310). As a result, the conductive material inside the plurality of first storage units (320) is discharged through each of the second storage units (330) and flows out onto the skin of the animal. As a result, the skin of the animal and the electrode unit (220) are electrically connected.

[0099] The cross-section of the second storage unit (330) is formed narrower than the cross-section of the first storage unit (320). As a result, the conductive material within the first storage unit (320) can maintain its storage state without flowing out into the second storage unit (330), which is narrower than the cross-section of the first storage unit (320), due to surface tension in the absence of an external force.

[0100] The third storage unit (350) is positioned so as to be connected to the rear side of the second storage unit (330), and its cross-section is formed to be wider than that of the second storage unit (330). This allows the conductive material discharged to the second storage unit (330) to have a sufficient area in contact with the skin, facilitating the collection of biosignals.

[0101] The partition wall (340) is a partition wall member formed spaced apart from each other around the perimeter of each of the plurality of storage units, and prevents the movement of conductive material discharged to the rear of the main body (310). This partition wall (340) may be formed in a circular shape centered on the storage unit (330), and may be formed in multiples.

[0102] For example, a partition wall (340) may be formed by providing a partition wall groove (341) on the outer periphery of the third storage unit (350). The shape of the partition wall (340) may be any shape as long as it blocks the space between each storage unit.

[0103] Hereinafter, a method of using the brainwave sensor of the present invention will be briefly described. After the user fixes the fixed band to the animal's head, the connector (250) of the electrode assembly (200) is connected to an external device, and preparation for brainwave signal collection is completed, the user presses the front side of the electrode unit (220) so that the conductive material inside the first storage unit (320) is discharged to the animal's skin through the second and third storage units (330, 350). At this time, the position of the electrode unit (220) can be confirmed by the character pattern (130).

[0104] When a conductive material is discharged and reaches the animal's skin, the animal's skin and the electrode unit (220) are electrically connected, and the electrode unit (220) collects the animal's brain wave signal. The collected brain wave signal is transmitted to an external device through the electrode unit (220), the wiring unit (230), and the connector unit (250).

[0105] The method of using the brainwave sensor described above may be changed in some order depending on the user's convenience or situation.

[0106]

[0107] The fixed band for the brainwave sensor of the present invention and the brainwave sensor using the same can stably fix the electrode for brainwave measurement to the head of the animal by fixing the electrode to the head of the animal using the head and ears of the animal.

[0108] In addition, the present invention has a fixed band made of a flexible material such as a urethane film or non-woven fabric, so that it can be flexibly wrapped around the head and ears of the animal and stably fixed thereto according to the head and ear positions of the animal.

[0109] In addition, the present invention enables the fixing band to be easily and quickly fixed to the animal's head by connecting the head fixing part and the ear fixing part by a detachable member.

[0110] In addition, the length of the first head fixing part of the present invention is formed to be shorter than the length of the second head part, so that the attachment location of the head fixing part is located on the side of the animal's face, thereby allowing the user to easily attach the head fixing part.

[0111] Additionally, the present invention can replace the operation of connecting the third ear fixing part to the head fixing part by inserting one ear of the animal into the ear insertion hole formed by the third ear fixing part.

[0112] In addition, the present invention forms a groove between the ear fixing parts, so that when each ear fixing part is bent to wrap around the ear, it can bend more flexibly and improve skin adhesion.

[0113] The present invention described above can be implemented in various other forms without departing from its technical spirit or essential characteristics. Therefore, the above embodiments are merely illustrative in all respects and should not be construed as limiting.

[0114] The present invention provides a fixed band for an EEG sensor for fixing an electrode for collecting EEG signals of an animal including a human to the head, and an EEG sensor using the same.
