Description

Technical Field

[0001] This invention relates to the field of ADHD treatment technology, and more specifically to a training device for treating ADHD in children. Background Technology

[0002] Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. Its core symptoms include inattention, hyperactivity, and impulsive behavior. Neurofeedback training based on electroencephalographic signals has become an important adjunctive treatment method. This therapy usually requires children to wear a special head-mounted training device. Sensors on the device collect attention-related physiological signals such as brain waves in real time and provide audiovisual feedback to help children learn and improve their concentration. Currently, head-mounted training devices typically include a frame that can be worn on the head, sensing components for signal acquisition, and a mechanical adjustment mechanism for initial adaptation to different head sizes.

[0003] However, existing devices mainly rely on mechanical clamping or the physical pressure of elastic bands for fixation, which makes it difficult to fit closely to the irregular head shape of children. Since children with ADHD have difficulty staying still and their heads are prone to shaking, the device may loosen during head shaking, resulting in unstable contact pressure between the sensing components and the scalp, changes in contact position, signal interruption or increased noise, affecting the accuracy of attention state judgment, and thus causing large training feedback errors.

[0004] To ensure signal quality, the sensing end must be in direct contact with the scalp. However, current technology relies on users or parents manually and repeatedly parting their hair before wearing the device. When children wear the device themselves, it cannot be guaranteed that their hair will completely detach from the sensing area, resulting in signal quality being affected by hair isolation. Summary of the Invention

[0005] The purpose of this invention is to provide a training device for the treatment of ADHD in children, which solves the problems mentioned in the background art.

[0006] To address the shortcomings of existing technologies, this invention provides a training device for the treatment of ADHD in children, comprising:

[0007] Housing assembly, rear housing assembly, and sensing assembly;

[0008] The outer shell assembly and the rear shell assembly are arranged sequentially along the first direction;

[0009] An adjustable headband assembly, connected between the outer shell assembly and the rear shell assembly, is used to adjust the distance between the outer shell assembly and the rear shell assembly to accommodate different users' head circumferences;

[0010] The adaptive component includes a pressure sequence switching mechanism and two airbags, the two airbags being spaced apart along a first direction and respectively connected to the opposite inner sides of the outer shell assembly and the rear shell assembly, the contact surfaces of the airbags being used to contact the user's head;

[0011] The sensing end of the sensing component is disposed on the contact surface of the airbag along the first direction;

[0012] The pressure sequence switching mechanism is mounted on the outer shell assembly. The air inlet of the pressure sequence switching mechanism is connected to an air source. One of the outputs of the pressure sequence switching mechanism is connected to an airbag, and the other output is connected to a support shell mounted on the airbag.

[0013] A cleaning mechanism is provided on the support shell along the first direction. The cleaning mechanism and the sensing end of the sensing component are coaxially arranged to blow away the hair between the sensing end and the skin. A ventilation mechanism is provided on the support shell along the third direction. The outlet of the ventilation mechanism is connected to the air guide groove opened on the contact surface of the airbag. The air guide groove extends along the contact surface of the airbag, and multiple air guide grooves are spaced apart along the second direction to uniformly deliver air to the head surface.

[0014] Preferably, the adjustable headband assembly includes three straps and a clamping mechanism, wherein one strap is mounted on the surface of the outer shell assembly along a second direction, and the other two straps are spaced apart along a third direction, with one end fixed to the vertical end face of the outer shell assembly. Parts of the straps are located inside the rear shell assembly, and both ends of the straps extend out from inside the rear shell assembly. The clamping mechanism is disposed on the rear shell assembly for locking the straps.

[0015] Preferably, the pressure sequence switching mechanism includes a sequence valve, a first air outlet pipe and a second air outlet pipe. The sequence valve is fixedly installed in an installation cavity opened inside the housing assembly. The air inlet of the sequence valve extends from the surface of the housing assembly along a second direction. One end of the first air outlet pipe is connected to the first air outlet end of the sequence valve. The first air outlet pipe passes through the housing assembly and the airbag along a first direction, and its end is located in the inner cavity of the airbag.

[0016] Preferably, one end of the second vent pipe is connected to the second vent end of the sequence valve, and the second vent pipe extends out of the housing assembly along the first direction and into the support housing.

[0017] Preferably, the adaptive component further includes a connecting pipe and a vent pipe, the connecting pipe passing through the outer shell assembly and the rear shell assembly, and the end of the connecting pipe being connected to the support shell;

[0018] Preferably, the ventilation tube is arranged sequentially along the first direction and the airbag, with both ends of the ventilation tube inserted into the airbag and communicating with the inner cavity of the airbag.

[0019] Preferably, the cleaning mechanism includes an annular groove formed on the surface of the support shell along a first direction. The bottom of the annular groove along the first direction has an air outlet groove communicating with the interior of the support shell. An elastic block is bonded to the bottom of the annular groove along the first direction. A sealing ring is bonded to the surface of the elastic block away from the support shell. A retaining strip is provided on the surface of the sealing ring near the support shell. The retaining strip extends out from the air outlet groove, and the inclined block on the retaining strip contacts the inner surface of the support shell along the first direction.

[0020] Preferably, the ventilation mechanism includes an air outlet, a connecting plate, a sealing plate, and a limiting plate. The air outlet is opened on the surface of the support shell along the third direction. The connecting plate is slidably connected to the air outlet along the third direction. The sealing plate and the limiting plate are respectively fixed at both ends of the connecting plate along the third direction. The sealing plate and the surface of the support shell along the third direction abut against each other to seal the air outlet.

[0021] Preferably, a return spring is fixedly connected to the opposing surfaces of the limiting plate and the sealing plate, and the other end of the return spring is fixed to the surface of the support shell.

[0022] Preferably, the sensing component includes a sensor and an electronic control mechanism arranged sequentially along a first direction. The sensor is mounted on the surface of the support shell along the first direction, and the electronic control mechanism is mounted on the mounting cavity wall of the shell assembly. The electronic control mechanism and the sensor are electrically connected by a wire.

[0023] The beneficial effects of this invention are reflected in:

[0024] 1. An adjustable headband is used for initial head fitting. Then, a pressure sequence switching mechanism controls the inflation of the airbag, allowing it to adaptively fill the gaps between the outer shell and back shell components and the irregular head contours for a tight fit. This improves wearing stability and prevents displacement caused by unconscious movements in children with ADHD. It can stably press the sensing end of the sensor component onto the scalp. The pressure sequence switching mechanism switches the output end to supply air into the support shell. The airflow first passes through a cleaning mechanism to blow away any hair that may be obstructing the sensor, ensuring direct contact between the sensor and the skin. This reduces the problem of hair interfering with the sensing and minimizes signal noise and interference caused by looseness and hair obstruction. The stable contact between the sensor and the skin without hair interference improves the authenticity and stability of the device's feedback data.

[0025] 2. Airflow is guided through the ventilation mechanism to the air guide channels on the airbag contact surface, accelerating airflow at the scalp-airbag contact interface. This effectively dissipates local heat and sweat, preventing discomfort caused by stuffiness and dampness. Simultaneously, it avoids the airbag expanding and contracting due to body temperature, which could lead to unstable pressure on the head. Ventilation and stable pressure improve the device's wearing comfort, reducing children's resistance and encouraging them to cooperate in completing required single and long-term repetitive training sessions.

[0026] 3. The pressure sequence switching mechanism controls the airbag pressure, which, in conjunction with the adjustable headband component, ensures stable and reliable contact between the sensor end of the sensing component and the skin. Furthermore, the pressure sequence switching mechanism controls the ventilation mechanism to guide air into the air channel, maintaining wearing comfort. This ensures the stability and accuracy of signal transmission from the sensing end and maintains a good wearing experience throughout the training process, thereby increasing children's willingness to use the device and their training compliance, and guaranteeing the effectiveness of attention training.

[0044] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0045] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0046] like Figures 1-9 As shown, a training device for treating ADHD in children includes:

[0047] Housing assembly 100, rear housing assembly 200, and sensing assembly 500;

[0048] The outer shell assembly 100 and the rear shell assembly 200 are arranged sequentially along the first direction;

[0049] An adjustable headband assembly 300 is connected between the outer shell assembly 100 and the rear shell assembly 200 to adjust the distance between the outer shell assembly 100 and the rear shell assembly 200 to accommodate different users' head circumferences;

[0050] The adaptive component 400 includes a pressure sequence switching mechanism 410 and two airbags 420. The two airbags 420 are spaced apart along a first direction and are respectively connected to the inner sides of the outer shell component 100 and the rear shell component 200. The contact surface of the airbags 420 is used to contact the user's head.

[0051] The sensing end of the sensing component 500 is disposed on the contact surface of the airbag 420 along the first direction;

[0052] The pressure sequence switching mechanism 410 is disposed on the housing assembly 100. The air inlet of the pressure sequence switching mechanism 410 is connected to the air source. One of the output ends of the pressure sequence switching mechanism 410 is connected to the airbag 420, and the other output end of the pressure sequence switching mechanism 410 is connected to a support shell 440 disposed on the airbag 420.

[0053] A cleaning mechanism 460 is provided on the support shell 440 along the first direction. The cleaning mechanism 460 and the sensing end of the sensing component 500 are coaxially arranged to blow away the hair between the sensing end and the skin. A ventilation mechanism 470 is provided on the support shell 440 along the third direction. The outlet of the ventilation mechanism 470 is connected to the air guide groove 421 opened on the contact surface of the airbag 420. The air guide groove 421 extends along the contact surface of the airbag 420, and multiple air guide grooves 421 are spaced apart along the second direction to uniformly deliver air to the head surface.

[0054] By providing the outer shell assembly 100 and the rear shell assembly 200 as a rigid frame for the device, and the adjustable headband assembly 300 as a connecting and adjusting component between the outer shell assembly 100 and the rear shell assembly 200, the distance between the outer shell assembly 100 and the rear shell assembly 200 can be adjusted by changing the length of the adjustable headband assembly 300, thereby directly adapting to different head circumferences of children. The adaptive assembly 400 is used to achieve both therapeutic and comfort aspects of the device. The airbag 420 acts as a flexible interface in contact with the head, and can be inflated to conform to the head contour and provide appropriate pressure. The pressure sequence switching mechanism 410 receives an external air source and distributes the airflow sequentially to the airbag 420 and the support shell 440 according to the pressure sequence. The sensing end of the sensing assembly 500 is located in the airbag 420. On the contact surface of 20, physiological signals of the head are collected. By setting the cleaning mechanism 460 coaxial with the sensing end, airflow can be blown out axially to blow away hair that may block the sensing end, ensuring direct contact between the sensing end and the skin, and ensuring the signal collection quality of the sensing component 500. The ventilation mechanism 470 is connected to the air guide groove 421 on the airbag 420, and delivers airflow to the closed space between the airbag 420 and the scalp. The airflow is evenly distributed on the scalp surface through multiple parallel air guide grooves 421, effectively improving the stuffiness during wearing, improving comfort and wearing compliance. The cleaning mechanism 460 ensures the reliability of signal collection, and the ventilation mechanism 470 achieves uniform ventilation of the scalp through the air guide grooves 421, jointly improving the treatment effectiveness of the device and the user's wearing comfort.

[0055] In this embodiment, as a preferred option, the adjustable headband assembly 300 includes three straps 310 and a clamping mechanism 320. One strap 310 is installed on the surface of the outer shell assembly 100 along the second direction, and the other two straps 310 are spaced apart along the third direction, with one end fixed to the vertical end face of the outer shell assembly 100. Parts of the straps 310 are located inside the rear shell assembly 200, and both ends of the straps 310 extend out from inside the rear shell assembly 200. The clamping mechanism 320 is disposed on the rear shell assembly 200 and is used to lock the straps 310.

[0056] By setting three straps 310, one strap 310 serves as support and the other two as limits on both sides of the head, a balanced binding force can be provided from the top of the head and the two sides to ensure the stability of the device when worn and prevent it from shifting or falling off due to head shaking during training. One end of the three straps 310 is fixed to the outer shell assembly 100, and the strap body passes through the interior or structure of the rear shell assembly 200. Both ends of the straps eventually emerge from the rear shell assembly 200. The clamping mechanism 320 is installed on the rear shell assembly 200 and acts on the emerging straps 310. The tightness is adjusted by pulling the free end of the straps 310 to make the device fit the head. Then, the clamping mechanism 320 locks the straps 310 to fix the adjusted length and complete the head circumference adaptation. The clamping mechanism 320 is existing technology and belongs to conventional technical means in the prior art.

[0057] In this embodiment, as a preferred option, the pressure sequence switching mechanism 410 includes a sequence valve 411, a first air outlet pipe 412, and a second air outlet pipe 413. The sequence valve 411 is fixedly installed in the mounting cavity opened in the housing assembly 100. The air inlet of the sequence valve 411 extends from the surface of the housing assembly 100 along the second direction. One end of the first air outlet pipe 412 is connected to the first air outlet end of the sequence valve 411. The first air outlet pipe 412 passes through the housing assembly 100 and the airbag 420 along the first direction, and its end is located in the inner cavity of the airbag 420.

[0058] The sequence valve 411 is the core of the pressure sequence switching mechanism 410. As a pneumatic control valve, it first opens at the first outlet end to allow air to enter the first outlet pipe 412, inflating the airbag 420. This causes the airbag 420 to inflate and expand to conform to the head's contours, providing adaptive wrapping and fixation for the head, thus offering stable support for subsequent pneumatic operations. When the pressure in the first outlet pipe 412 reaches a set value, the first outlet end closes, and the second outlet end opens to allow air to exit through the second outlet pipe 413.

[0059] In this embodiment, as a preferred option, one end of the second vent pipe 413 is connected to the second vent end of the sequence valve 411, and the second vent pipe 413 extends out of the outer shell assembly 100 along the first direction and extends into the support shell 440.

[0060] Under the control of the sequence valve 411, after the airflow completes the inflation of the airbag 420, and the pressure of the airbag 420 reaches the preset value, the sequence valve 411 switches to supply air to the second air outlet pipe 413. The second air outlet pipe 413 connects the second air outlet end of the sequence valve 411 with the internal space of the support shell 440. The second air outlet pipe 413 supplies air to the internal cavity of the support shell 440, providing a controlled air source for the cleaning mechanism 460 and the ventilation mechanism 470 integrated in the support shell 440.

[0061] In this embodiment, as a preferred option, the adaptive component 400 further includes a connecting pipe 430 and a vent pipe 450. The connecting pipe 430 passes through the outer shell component 100 and the rear shell component 200, and the end of the connecting pipe 430 is connected to the support shell 440.

[0062] The ventilation tube 450 and the airbag 420 are arranged sequentially along the first direction, and the two ends of the ventilation tube 450 are respectively inserted into the airbag 420 and communicate with the inner cavity of the airbag 420.

[0063] By connecting the two support shells 440 with a connecting tube 430, air can be released from both shells. A venting tube 450 is positioned between the two airbags 420, with both ends inserted into the interiors of each airbag 420, thus connecting their internal cavities. The connecting tube 430 allows the pressure of the two independent airbags 420 to automatically balance after inflation. When an irregular head shape causes greater pressure on one airbag 420, gas can flow through the venting tube 450 to the side with less pressure. This results in a more even pressure distribution on both sides of the head, avoiding discomfort from excessive pressure at a single point, and improving wearing comfort and self-adaptive fit.

[0064] In this embodiment, as a preferred solution, the cleaning mechanism 460 includes an annular groove 461, which is formed on the surface of the support shell 440 along the first direction. The bottom of the annular groove 461 along the first direction is provided with an air outlet groove 462 that communicates with the inside of the support shell 440. An elastic block 463 is bonded to the bottom of the annular groove 461 along the first direction. A sealing ring 464 is bonded to the surface of the elastic block 463 away from the support shell 440. A retaining strip 465 is provided on the surface of the sealing ring 464 near the support shell 440. The retaining strip 465 extends out from the air outlet groove 462, and the inclined block on the retaining strip 465 contacts the inner surface of the support shell 440 along the first direction.

[0065] When the sequence valve 411 switches, the airflow enters the inner cavity of the support shell 440 through the second air outlet pipe 413, causing the airflow to be discharged from the air outlet groove 462 to form a ring of airflow to sweep the area in front of the sensing end, automatically blowing away any hair that may be obstructing the sensor, ensuring that the sensing end is in direct contact with the skin, and reducing the problem of hair interfering with the sensing. During the process of the sensing end being in contact with the skin, the skin first contacts the sealing ring 464, which then causes the sealing ring 464 to move towards the support shell 440, thereby causing the sealing ring 464 to squeeze the elastic block 463, so that the sealing ring 464 enters the ring groove 461 and seals the ring groove 461, thereby increasing the air pressure inside the support shell 440.

[0066] In this embodiment, as a preferred option, the ventilation mechanism 470 includes an air outlet 471, a connecting plate 472, a sealing plate 473, and a limiting plate 474. The air outlet 471 is opened on the surface of the support shell 440 along the third direction. The connecting plate 472 is slidably connected to the air outlet 471 along the third direction. The sealing plate 473 and the limiting plate 474 are respectively fixed at both ends of the connecting plate 472 along the third direction. The sealing plate 473 abuts against the surface of the support shell 440 along the third direction to seal the air outlet 471.

[0067] After the annular groove 461 is closed, the air pressure inside the support shell 440 increases. The air pressure squeezes the sealing plate 473 away from the support shell 440, thereby separating the sealing plate 473 from the support shell 440. This allows air to be expelled from the air outlet 471. The sealing plate 473 drives the connecting plate 472 to move, allowing the connecting plate 472 to slide within the air outlet 471. The connecting plate 472 can cooperate with the air outlet 471 to guide the movement of the sealing plate 473. The connecting plate 472 drives the limiting plate 474 to move, allowing air to enter the air guide groove 421. This increases the airflow velocity within the air guide groove 421, providing cooling to the area where the airbag 420 contacts the skin.

[0068] In this embodiment, as a preferred option, a return spring 475 is fixedly connected to the opposing surfaces of the limiting plate 474 and the sealing plate 473, and the other end of the return spring 475 is fixed to the surface of the support shell 440.

[0069] By setting a reset spring 475, the limiting plate 474 can be easily reset. When the air pressure inside the support shell 440 increases, the sealing plate 473 moves and drives the limiting plate 474 to move along with the sealing plate 473 through the connecting plate 472, thereby squeezing the reset spring 475. When the air pressure inside the support shell 440 decreases, the reset spring 475 resets, thereby resetting the limiting plate 474, which in turn drives the sealing plate 473 to reset through the connecting plate 472, thereby making it easier to close the air outlet 471 and re-close the air outlet 471.

[0070] In this embodiment, as a preferred option, the sensing component 500 includes a sensor 510 and an electronic control mechanism 520 arranged sequentially along a first direction. The sensor 510 is mounted on the surface of the support shell 440 along the first direction, and the electronic control mechanism 520 is mounted on the mounting cavity wall of the outer shell component 100. The electronic control mechanism 520 and the sensor 510 are electrically connected by a wire.

[0071] Sensor 510, as the signal acquisition front end, is directly mounted on the surface of the support shell 440 facing the head so as to make the closest contact with or get close to the scalp to collect EEG signals. The electronic control mechanism 520 is placed in the mounting cavity of the outer shell assembly 100 as the signal processing and control center. Sensor 510 and electronic control mechanism 520 are connected by flexible wires to form a complete signal link.

[0072] Working principle: In use, the user first wears the adjustable headband 300. After wearing it, the external air source is activated, and the airflow first enters the first outlet of the sequence valve 411 in the pressure sequence switching mechanism 410 installed in the outer shell assembly 100. The airflow then enters the inner cavity of the two airbags 420 through the first outlet pipe 412. Since the two airbags 420 are connected by the ventilation pipe 450, the two airbags 420 begin to inflate synchronously. When the airbags 420 inflate to a certain pressure, the second outlet of the sequence valve 411 opens, and the airflow then flows through the second outlet. The airflow is delivered through pipe 413 and connecting pipe 430 to the internal cavity of the support shell 440 located on the airbag 420. At this time, the airflow is discharged from the air outlet 462, forming a ring-shaped airflow that sweeps the area in front of the sensor end, automatically blowing away any hair that may be obstructing it, ensuring that the sensor end is in direct contact with the skin, and reducing the problem of hair interfering with the sensing. Then, the pull strap 310 is tightened, so that the free end of the pull strap 310 slides within the rear shell assembly 200. During the process of the sensor end contacting the skin, the skin first contacts the sealing ring 464, which then moves the sealing ring 464 towards the support shell 440, thereby sealing the airbag. Ring 464 compresses elastic block 463, causing sealing ring 464 to enter ring groove 461 and seal ring groove 461. This increases the air pressure inside support shell 440, and then the contact surface of airbag 420 gradually conforms to the forehead and back of the user's head. The ventilation tube 450 connecting the two airbags 420 ensures that the air pressure inside the two airbags 420 is automatically balanced, making the pressure applied to the head uniform and gentle, achieving personalized adaptive wrapping and fixation, while avoiding the discomfort of hard pressure. After the ring groove 461 is sealed, the air pressure inside support shell 440 increases, and the air pressure pushes the sealing plate 4... 73 is squeezed away from the support shell 440, which causes the sealing plate 473 to separate from the support shell 440, allowing air to be expelled from the air outlet 471. The sealing plate 473 drives the connecting plate 472 to move, allowing the connecting plate 472 to slide within the air outlet 471. The connecting plate 472 can cooperate with the air outlet 471 to guide the movement of the sealing plate 473. The connecting plate 472 drives the limiting plate 474 to move, allowing air to enter the air guide groove 421, which in turn increases the airflow velocity within the air guide groove 421, thus blowing air to cool the area where the airbag 420 contacts the skin.
