Description

Technical Field

[0001] The present invention relates to the technical field of electroencephalogram examination, and specifically relates to an electroencephalogram examination device for cranial nerve feedback training. Background Art

[0002] Cranial nerve feedback training, also known as learning ability improvement training, is a non-invasive and side-effect-free brain training technology. Based on the principle of neural plasticity, it is connected to a computer through a nerve feedback training instrument to detect and feedback the brain activity state in real time. Combining the actual situation of the brain, it uses specified computer games to assist in exercising the cranial nerves. This training can improve attention, concentration, memory, self-control ability, and IQ, making the brain more sensitive. This technology is widely used in fields such as education and medical treatment, and has a positive effect on improving symptoms such as attention deficit hyperactivity disorder and autism.

[0003] The electroencephalogram examination device includes a plurality of electrode patches placed on the inner side of the helmet. When the helmet is worn on the head, the electrode patches touch the scalp surface, enabling electroencephalogram examination work. However, there are many electrode patches inside the helmet, and together with the weight of the helmet body, the overall structure is relatively heavy. And the electroencephalogram examination lasts for a relatively long time. When worn for a long time, the burden on the head of the detector is relatively large. Therefore, we propose an electroencephalogram examination device for cranial nerve feedback training. Summary of the Invention

[0004] The purpose of the present invention is to provide an electroencephalogram examination device for cranial nerve feedback training. By setting the vertical frame to be slidably placed in the through-hole of the horizontal plate, and the horizontal plate can rotate, the position of the vertical frame can be changed arbitrarily to facilitate the wearer to use it in different positions. And a suspension rope is connected above the helmet, passes around the fixed pulley in the vertical frame and is connected to a counterweight block at its end. The weight of the counterweight block is less than the overall weight of the helmet, which can lift the helmet upward and reduce the burden on the head of the person to be detected when wearing it, making it more comfortable during long-term detection, and solving the problems raised in the background art.

[0005] To achieve the above object, the present invention provides the following technical solution: An electroencephalogram examination device for cranial nerve feedback training, comprising a pillar, a collar, a cross plate, a vertical frame and a helmet; the pillar is vertically fixed above the side of the counterweight base, the collar is rotatably sleeved on the outer ring above the pillar, and limiting plates close to the collar are fixed on the outer rings of the pillar above and below the collar, and the cross plate is transversely welded and fixed on the side of the collar; an airbag is fixedly attached to the inner upper surface of the helmet, and a plurality of electrode patches are evenly and fixedly attached to the inner surface below the airbag; a transverse through opening is formed on the surface of the cross plate, the vertical frame is vertically slidably placed in the through opening, and side plates are transversely fixed on both sides of the vertical frame above and below the cross plate, through openings are formed through both sides of the surface of each side plate, and support rollers that support and contact the surface of the cross plate are rotatably installed in the through openings; the bottom of the vertical frame communicates with the outside, a fixed pulley is rotatably installed above the vertical frame inside, a partition is vertically fixed inside the vertical frame below the fixed pulley, the helmet is placed below the vertical frame, a suspension rope penetrating into the vertical frame is connected above the helmet, the suspension rope passes through from one side of the partition, bypasses the fixed pulley and then penetrates into the vertical frame on the other side of the partition, and a counterweight block that can be lifted and lowered in the vertical frame on the side of the partition is fixed at the other end of the suspension rope, and the weight of the counterweight block is less than the overall weight of the helmet.

[0006] By adopting the above technical solution, the helmet is worn on the head of the person to be tested. When the airbag is inflated, the electrode patches on the inner surface of the airbag contact the scalp surface. Under the action of the counterweight block, the helmet is lifted upward by the suspension rope, reducing the burden on the wearer's head. Moreover, the cross plate can rotate in angle, and the vertical frame can slide left and right freely in the through opening of the cross plate, facilitating the wearer to wear and use it in different positions.

[0008] By adopting the above technical solution, the collar can rotate on the outer ring of the pillar between the limiting blocks. When rotating, the rolling balls support between the collar and the limiting ring, avoiding contact between the collar and the limiting ring and making the rotation smooth.

[0009] As a preferred embodiment of the present invention, a plurality of wheel grooves are evenly formed on the inner surface of the collar, and rotatable support wheels are installed in the wheel grooves, and the support wheels support on the surface of the pillar.

[0010] By adopting the above technical solution, when the collar is placed on the outer ring of the pillar and rotates, the support wheels support and roll on the surface of the pillar, avoiding contact between the collar and the pillar, and thus making the rotation smooth.

[0011] As a preferred embodiment of the present invention, a buffer plate is horizontally fixed between the partition plate and the vertical frame above the counterweight block. The lifting rope passes through the buffer plate through the rope opening on the surface of the buffer plate, and a spring is sleeved outside the lifting rope above the counterweight block.

[0012] By adopting the above technical solution, when the helmet is not worn and the helmet falls downward, when the counterweight block rises to a height close to the buffer plate, the spring abuts against the lower surface of the buffer plate and is compressed, which can play a role in buffer protection.

[0014] By adopting the above technical solution, when the vertical frame slides left or right in the through opening, the rubber pads can play a role in buffering the impact of the vertical frame against the left or right side in the through opening.

[0015] As a preferred embodiment of the present invention, the airbag is communicated with an air charging pipe penetrating to the outside of the helmet, and a solenoid valve is installed on the air charging pipe.

[0021] As a preferred embodiment of the present invention, a connecting ring is fixedly arranged at the middle position on the surface of the helmet, and the lifting rope is connected and fixed to the top of the helmet through the connecting ring.

Specific implementation mode

[0035] Please refer to Figures 1-6 , the present invention provides a technical solution: an electroencephalogram inspection device for cranial nerve feedback training, including a support pillar 1, a collar 2, a cross plate 3, a vertical frame 4 and a helmet 5; wherein the helmet 5, as a device for carrying the electrode patches 521, can be worn on the outer circle of the user's head. An airbag 52 is fixedly attached to the inner upper surface of the helmet 5, and a plurality of electrode patches 521 are evenly and fixedly attached to the inner surface of the airbag 52. The electrode patches 521 are connected to a computer for detection through a data line (not shown in the figure). The airbag 52 is communicated with an inflatable tube 522 that penetrates to the outside of the helmet 5, and a solenoid valve is installed on the inflatable tube 522. When in use, the inflatable tube 522 is connected to a high-pressure gas source, and a groove 54 is provided on the surface of the helmet 5, and an air release solenoid valve 523 communicated with the airbag 52 is installed in the groove 54.

[0036] When in use, both the solenoid valve and the air release solenoid valve 523 are connected to a control computer. First, the helmet 5 is worn on the user's head. By controlling the solenoid valve or the air release solenoid valve 523 on the inflatable tube 522, the purpose of inflating or deflating the airbag 52 is achieved, and then the purpose of expanding or contracting the airbag 52 is achieved. It can be adapted to heads of different sizes, so that the electrode patches 521 are in contact with the scalp surface of the user. A sponge block 53 is fixedly attached to the inner circle of the helmet 5 in a surrounding manner. The sponge block 53 is placed on the inner circle surface of the helmet 5 below the airbag 52. After the head is put on, the sponge block 53 surrounds and abuts against the outer circle of the user's head, which can play a role in stably binding the helmet 5. Then, the electroencephalogram inspection work can be carried out.

[0037] A counterweight base 11 is provided at the bottom of the support column 1, and the support column 1 is vertically fixed above the side of the counterweight base 11. The self-weight of the counterweight base 11 can ensure that the support column 1 and the structure above it maintain sufficient stability during support. The collar 2 is rotatably sleeved on the outer ring above the support column 1. Limiting plates 12 close to the collar 2 are fixed on the outer rings of the support column 1 above and below the collar 2. The cross plate 3 is horizontally welded and fixed to the side of the collar 2. The collar 2 can rotate around the outer ring of the support column 1, thereby changing the angle of the cross plate 3 to meet the usage requirements.

[0038] In order to enable the collar 2 to rotate smoothly around the outer ring of the support column 1 and maintain the horizontal stability of the cross plate 3, first, rolling grooves 13 are circumferentially formed on the outer rings above and below the collar 2 and on the outer rings of the limiting plates 12 on its opposite side. The rolling grooves 13 on the surface of the collar 2 are aligned with those on the surface of the limiting plates 12 and have the same size. A plurality of balls 14 are rotatably placed between the rolling grooves 13 of the collar 2 and the limiting plates 12. When the collar 2 rotates around the outer ring of the support column 1, the balls 14 rotate in the rolling grooves 13, enabling the collar 2 to rotate smoothly and stably around the outer ring of the support column 1. To further improve the smoothness and stability during rotation, a plurality of wheel grooves 21 are evenly formed on the inner surface of the collar 2, and rotatable supporting wheels 211 are installed in the wheel grooves 21. The supporting wheels 211 support on the surface of the support column 1. When the collar 2 rotates around the outer ring of the support column 1, the supporting wheels 211 roll on the outer ring of the support column 1, further enhancing the stability and smoothness of the rotation of the collar 2 driving the cross plate 3.

[0039] A horizontally and vertically penetrating through-opening 31 is formed on the surface of the cross plate 3, and the width of the vertical frame 4 is slightly smaller than the width of the through-opening 31, enabling the vertical frame 4 to be vertically slidably placed in the through-opening 31. The vertical frame 4 can move left or right in the through-opening 31. Horizontally fixed side plates 41 are provided on both sides of the vertical frame 4 above and below the cross plate 3. Through openings 411 are formed through both sides of the surface of each side plate 41, and supporting rollers 412 that support and contact the surface of the cross plate 3 are rotatably installed in the through openings 411. When the vertical frame 4 slides left or right in the through openings 411, the upper and lower supporting rollers 412 roll on the surface of the cross plate 3, smoothly driving the vertical frame 4 to slide left or right.

[0040] Rubber pads 42 are fixed on both sides of the surface of the vertical frame 4 at the position of the through-opening 31. The rubber pads 42 are fixed to the surface of the vertical frame 4 by fitting. Since there is no driving force when the vertical frame 4 slides left and right, it is easy for the vertical frame 4 to hit the ends of the through-opening 31 when sliding left or right. At this time, due to the presence of the rubber pads 42, the vertical frame 4 hits and contacts the left or right surface inside the through-opening 31 through the rubber pads 42, using the rubber pads 42 to provide a buffering and protective effect.

[0041] The bottom of the vertical frame 4 is connected to the outside, and a fixed pulley 44 is rotatably installed above the inside of the vertical frame 4. A partition 43 is vertically fixed inside the vertical frame 4 below the fixed pulley 44. The partition 43 is located at a position slightly offset to the left of the middle inside the vertical frame 4. The helmet 5 is placed below the vertical frame 4. A suspension rope 6 that penetrates into the vertical frame 4 is connected above the helmet 5. A connection ring 51 is fixed at the middle position on the surface of the helmet 5. The suspension rope 6 is connected and fixed to the top of the helmet 5 through the connection ring 51. The suspension rope 6 penetrates upward into the vertical frame 4, passes through the left side of the partition 43, bypasses the fixed pulley 44, then penetrates into the vertical frame 4 on the right side of the partition 43, and extends downward. The other end of the suspension rope 6 is fixed with a counterweight 61. The counterweight 61 can move up and down in the vertical frame 4 on the right side of the partition 43, and the weight of the counterweight 61 is less than the overall weight of the helmet 5. When in use, the weight of the counterweight 61 pulls the suspension rope 6 downward. After the direction of the force is changed by the fixed pulley 44, it becomes an upward acting force to lift the helmet 5. Since the weight of the counterweight 61 is less than the weight of the helmet 5, it will not directly lift the helmet 5 upward, but only reduce the burden of the helmet 5 on the user's head, enabling the user to maintain good comfort during long-term use. At the same time, it can be adapted to users of different heights. When the height is too high, the helmet 5 will rise, while the height of the counterweight 61 will be lower. On the contrary, when the height is too low, the helmet 5 will lower, while the height of the counterweight 61 will be higher.

[0042] In addition, since the helmet 5 is placed below the vertical frame 4 and there are connection structures such as the suspension rope 6 between the helmet 5 and the vertical frame 4, during the use process, the cross plate 3 can rotate to different angles, and the vertical frame 4 can slide to different positions in the through hole 31 of the cross plate 3, enabling the vertical frame 4 to move to different positions. The user can wear the helmet 5 at different positions and achieve the above-mentioned use effects.

[0043] After the helmet 5 is removed from the head after use, the helmet 5 loses the support of the head and will fall downward, causing the counterweight 61 to rise. A buffer plate 45 is horizontally fixed between the partition 43 and the vertical frame 4 above the counterweight 61. A through rope hole 451 is opened at the middle position on the surface of the buffer plate 45. The suspension rope 6 passes through the buffer plate 45 through the rope hole 451 on the surface of the buffer plate 45, and an outer ring of the suspension rope 6 above the counterweight 61 is sleeved with a spring 62. When the counterweight 61 quickly rises while the helmet 5 quickly descends, when the counterweight 61 quickly approaches the buffer plate 45, the spring 62 will be compressed, thereby playing a buffering role to avoid the counterweight 61 quickly hitting below the buffer plate 45, thus playing a protective role.

[0044] In use, first connect the inflation tube 522 to a high-pressure gas source. The solenoid valve and the air release solenoid valve 523 on the inflation tube 522 are both connected to the control computer, and the electrode patches 521 in the helmet 5 are connected to the electroencephalogram examination computer. During the examination, put the helmet 5 on the head of the person to be tested, and then control the opening time of the solenoid valve on the inflation tube 522 according to the size of the head of the person to be tested, so that an appropriate amount of high-pressure gas source is filled into the airbag 52, thereby causing the airbag 52 to expand and finally ensuring that the electrode patch touches the scalp surface of the person to be tested. The sponge block 53 surrounds the outer circle of the head to play a role in stabilizing the helmet 5. During the process of detecting the electroencephalogram, due to the gravitational force of the counterweight 61, the suspension rope 6 above the helmet 5 will be lifted upward. The weight of the counterweight 61 is less than the weight of the helmet 5, which will only pull the helmet 5 upward but will not directly lift the helmet 5, which can greatly reduce the burden on the head of the person to be tested caused by the overall structure such as the helmet 5. And when the position of the person to be tested changes, the collar 2 at the end of the cross plate 3 can rotate on the outer circle of the support column 1, thereby changing the position of the cross plate 3. When rotating, the ball 14 is placed between the limit plate 12 and the collar 2 and rolls in the rolling groove 13, and the support wheel 211 inside the collar 2 supports and rolls on the outer surface of the support column 1, so that the collar 2 can rotate stably and smoothly on the outer circle of the support column 1 and drive the cross plate 3 to rotate. At the same time, the vertical frame 4 can move left and right in a way that the support roller 412 supports and rolls on the surface of the cross plate 3. When the tester is in different positions, the above functions can be realized to achieve the purpose of reducing the burden on the head of the person to be tested caused by the helmet 5.
