Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a highly adaptable electroencephalogram (EEG) monitoring fixation headgear. Background Technology

[0002] Electroencephalography (EEG) monitoring, as a core tool for diagnosing neurological diseases, assessing sleep health, and monitoring postoperative brain function, places extremely high demands on monitoring duration and signal stability. The monitoring headgear, as the direct carrier for EEG acquisition, directly determines the stability of electrode fit, the comfort of prolonged wear, and the final quality of EEG signal acquisition through its ability to adapt to different head sizes.

[0003] Currently, the size adjustment methods for EEG monitoring headbands widely used in clinical and home settings generally rely on either hook and loop fasteners or an overall elastic wrapping system. Among these, the hook and loop fastener structure has become the mainstream choice due to its ease of use. However, this structure faces significant technical bottlenecks when considering the wide range of size adaptation needs across all age groups (from infants to the elderly) and for individuals with unusual head shapes (flat head, prominent occipital bone, temporal bulge).

[0004] To achieve a wide range of head circumference adjustments, sufficiently long hook and loop fasteners are necessary. However, the wearing space of head-mounted devices is limited. Overly long hook and loop fasteners can cause the headgear structure to stack and become bulky, making it cumbersome to wear and significantly increasing the feeling of pressure, which is not suitable for long-term continuous monitoring. If a simplified hook and loop fastener structure is used, although it can ensure that it is easy to wear, its adjustment range is severely insufficient, which can only cover a limited range of head circumference differences. It is difficult to adapt to people with irregular head shapes or different body types, resulting in loose electrodes and poor contact in some areas, or excessive compression in local areas, causing discomfort.

[0005] More importantly, the Velcro adjustment is essentially a "manual, one-time adjustment," lacking a travel amplification mechanism and incompatible with automated control methods. During the long duration of EEG monitoring, slight head movements, dynamic changes in muscle state, and slight skin relaxation or sweating continuously alter the electrode's contact with the scalp, causing the contact pressure to gradually decrease or resulting in localized suspension. Traditional manual adjustment methods cannot quantify contact pressure in real time, nor can they dynamically correct contact deviations during monitoring. This easily leads to unstable EEG signals, increased noise, and even signal interruptions, severely impacting the accuracy and reliability of the monitoring results.

[0006] While the overall elastic wrap-around headgear does not require additional adjustment components and relies on the elastic deformation of the fabric to achieve a certain range of head circumference adaptation, its reliance on continuous elastic tension to wrap the head across the entire area has inherent drawbacks: prolonged wear can cause continuous pressure on the scalp, easily leading to head soreness, poor blood circulation, and extremely poor wearing comfort; at the same time, the uniform deformation of the elastic fabric cannot adapt to the uneven contours of the head, easily resulting in excessive pressure on protruding parts and loose fit in concave parts, leading to uneven electrode contact pressure and significant differences in the stability of EEG signals in different channels, which cannot meet the requirements of high-precision monitoring.

[0007] In summary, the current mainstream adjustment methods for EEG monitoring headgear cannot effectively resolve the contradiction between structural simplification and large-scale size adjustment, nor can they achieve automated and dynamic fit compensation. Given the increasing demand in clinical and home health monitoring for headgear that can adapt to full-size heads, provide long-term low-pressure wear, and ensure stable and accurate signal acquisition, there is an urgent need for a highly adaptable EEG monitoring headgear that can achieve large-scale adaptive adjustment through a small-volume drive structure and automatically adapt to different head sizes and dynamic fit states. Summary of the Invention

[0008] The purpose of this invention is to provide a highly adaptable EEG monitoring fixation headgear that can automatically adjust according to the size of the patient's head.

[0009] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is: a highly adaptable EEG monitoring fixation headgear, comprising a cranial plate and an annular band, wherein a plurality of connecting straps for mounting detection electrodes are provided between the cranial plate and the annular band, and a pressure detection sensor is also provided at the detection electrode; an adjustment mechanism is provided on the cranial plate, which can automatically adjust the length of the effective segment of the connecting straps according to the detection pressure.

[0010] Preferably, the adjustment mechanism includes two strip-shaped adjustment plates, each with a plurality of winding shafts; one end of the connecting belt is connected to an annular belt loop, and the other end is wound around the winding shafts of the two adjustment plates, with its end fixedly connected to one of the adjustment plates.

[0011] The adjustment mechanism adjusts the distance between the two adjustment plates through the drive component, thereby adjusting the length of the effective section of the connecting strip.

[0012] Preferably, the drive assembly includes a miniature air pump, a diversion solenoid valve connected to the miniature air pump, and a regulating airbag connected to the diversion solenoid valve via a pipeline.

[0013] The regulating airbag is positioned between two adjustment plates, and the regulating airbag is equipped with an exhaust port and a venting solenoid valve.

[0014] The drive assembly controls the inflation amount of the airbag to adjust the spacing between the adjustment plates.

[0015] Preferably, the two adjustment plates are parallel to each other, and one of the two adjustment plates is fixedly connected to the top of the skull plate.

[0016] Preferably, one end of the two adjustment plates is connected to each other to form a V-shaped structure; the two adjustment plates are parallel to each other at the corner of the V-shape, forming an installation area for placing and controlling the airbag; a winding shaft is provided at the opening of the V-shape of the two adjustment plates, and one adjustment plate extends obliquely upward and the other extends horizontally at the opening of the V-shape.

[0017] Preferably, the connecting belt extends to the winding shaft after being reversed by a guide roller located on the side of the skull plate.

[0018] Preferably, a short horizontal plate is provided at the installation area, and the installation area is divided into upper and lower layers by the short horizontal plate, and an adjustable airbag is provided in both the upper and lower layers; the adjustment plate is fixedly connected to the top plate of the skull by the short horizontal plate, and adjustment spaces for the adjustment plate to swing are formed on the upper and lower sides of the two adjustment plates.

[0019] Preferably, the section of the connecting belt near the annular belt loop is a low-elasticity loading section, and the other section is a non-elastic winding section; the detection electrode and pressure sensor are both disposed on the loading section.

[0020] Preferably, it also includes a mounting cloth, the two ends of which are provided with hook and loop fasteners for fastening and covering the loading section, and the detection electrode and pressure sensor are both disposed on the mounting cloth.

[0021] Preferably, the loading section and the annular belt are detachably connected by a connecting buckle.

[0022] Preferably, the annular belt loop is provided with a D-ring buckle for adjusting the circumference of the annular belt loop.

[0023] Preferably, the bottom surface of the cranial plate is a flexible pad and is provided with detection electrodes.

[0024] The beneficial effects of this invention are mainly reflected in the following aspects: through precise structural design and automated control logic, it effectively solves the technical pain points of existing EEG monitoring headbands, such as inconvenient size adjustment, limited fit range, poor fit stability, and insufficient wearing comfort. The specific beneficial effects are as follows:

[0025] 1. Achieve automated and precise fitting for different head sizes, significantly improving the fitting range and accuracy. This invention uses pressure sensors at the detection electrodes to collect real-time pressure signals between the electrodes and the scalp. The adjustment mechanism automatically adjusts the length of the effective segment of the connecting band based on the pressure signals, eliminating the need for repeated manual adjustments. This completely solves the problems of traditional manual adjustments relying on experience, low accuracy, and poor fitting efficiency. Simultaneously, the connecting band is wound around the winding shafts of two adjustment plates. The distance between the two adjustment plates is adjusted by the drive component. Utilizing the stroke amplification effect of the winding path, a large span of length adjustment of the effective segment of the connecting band is achieved with a small stroke drive. This allows for flexible fitting of different head circumferences from children to adults, as well as various irregular head shapes such as flat heads and protruding occipital bones, resulting in a wide fitting range and precise adjustment.

[0026] 2. The adjustment mechanism balances adjustment range and precision, enhancing the flexibility of size adaptation. The adjustment mechanism employs a structure of two adjustment plates with a winding shaft, allowing for two optimal layouts to meet different adjustment needs: parallel adjustment plates offer a simple and stable structure, while the V-shaped adjustment plate, through its winding shaft at the opening and in conjunction with the control airbag in the installation area, further optimizes the winding path and adjustment stroke. Simultaneously, the installation area is divided into upper and lower layers by a short horizontal plate, both equipped with control airbags, enabling graded adjustments for coarse and fine work. This expands the overall adjustment range and improves the accuracy of size adaptation, specifically compensating for subtle differences in different head contours and ensuring uniform electrode fit.

[0027] 3. The drive assembly is rationally designed, offering smooth adjustment and strong controllability, suitable for long-term monitoring needs. The drive assembly uses a miniature air pump, a diversion solenoid valve, and a regulating airbag. By controlling the inflation volume of the regulating airbag, the spacing between the adjustment plates is adjusted. The adjustment process is smooth and without rigid impact, avoiding the problems of jamming and scalp pressure caused by traditional mechanical adjustments. The regulating airbag is equipped with an exhaust port and a deflation solenoid valve, which allows for bidirectional flexible adjustment of the effective length of the connecting strap. It can quickly tighten the connecting strap to ensure electrode fit, and also loosen it in time to avoid excessive pressure. At the same time, the combination of the miniature air pump and the diversion solenoid valve can achieve independent or synchronous adjustment of multiple connecting straps, adapting to the differentiated fit requirements of different head areas.

[0028] 4. Improve wearing comfort and electrode fit stability to ensure EEG monitoring signal quality. The connecting strap adopts a segmented design with a low-elasticity loading section and a non-elasticity winding section. The loading section provides only a small amount of fit compensation and does not generate continuous tension, effectively avoiding the defects of the entire elastic headgear that compresses the scalp, causing head soreness and poor blood circulation. The detection electrodes and pressure sensors are set on the low-elasticity loading section, which ensures the stability of electrode fit and reduces the feeling of pressure when wearing. At the same time, the guide roller optimizes the winding path of the connecting strap, avoiding the strap being pulled or twisted, further improving wearing comfort and fit stability, and ensuring the continuity and accuracy of EEG signal acquisition.

[0029] 5. The structure is detachable and easy to maintain, enhancing the practicality and reusability of the equipment. The detection electrodes and pressure sensors are covered on the loading section by the hook-and-loop area of ​​the cloth, facilitating the removal, cleaning, and replacement of the electrodes and sensors. The loading section and the annular belt are detachably connected by a buckle. The annular belt is equipped with a D-ring buckle for manual adjustment of the circumference, which not only facilitates the assembly, disassembly, cleaning, and disinfection of the equipment to meet clinical reuse needs, but also allows for initial coarse positioning of the head through the D-ring buckle. Combined with the automatic fine adjustment mechanism, this further enhances the flexibility and convenience of size adaptation.

[0030] 6. The overall structure is simple and lightweight, suitable for use in multiple scenarios, including clinical and home settings. This invention integrates the adjustment mechanism and drive components onto the top of the skull, resulting in a compact structure and small size without bulky or redundant components, making it easy to wear. Furthermore, the automated adjustment logic requires no manual intervention, making it easy to operate. It meets the high-precision requirements of long-term clinical EEG monitoring while also meeting the convenience needs of home health monitoring, making it widely applicable and highly practical.

[0036] The following is in conjunction with the appendix Figure 1-4 This invention provides a complete, detailed, and clear description of a highly adaptable EEG monitoring fixation headgear, enabling those skilled in the art to fully understand the technical solution, specific structure, operating principle, and workflow of the invention, and to repeatedly implement it. This embodiment is used to further explain the invention, not to limit the scope of protection.

[0037] like Figure 1 As shown, the invention comprises five parts: a top support structure, a circumferential adjustment structure, a bottom positioning structure, a detection and sensing structure, and an automatic drive structure. Specifically, it includes: a top plate 1, an annular band 2, several connecting straps 4, detection electrodes 3, a pressure sensor 5, and an adjustment mechanism 6. The top plate 1 is located at the very top of the headgear and supports the adjustment mechanism 6, drive elements, and control elements. The annular band 2 is located at the bottom of the headgear, encircling the user's head, and is used for initial positioning and basic fixation of the headgear. The connecting straps 4 are evenly distributed circumferentially around the head, with the upper end connected to the top plate 1 and the lower end connected to the annular band 2, forming a stable cage-like support structure. The connecting straps 4 serve as the main carriers for the detection electrodes 3 and can change their effective length under the drive of the adjustment mechanism 6, thereby achieving adaptive matching to head circumference and head shape contours.

[0038] To achieve automated, precise, and dynamic adjustment, this invention includes a pressure sensor 5 at each installation position of the detection electrode 3. The pressure sensor 5 maintains synchronous contact with the detection electrode 3, enabling real-time and accurate acquisition of the contact pressure signal between the detection electrode 3 and the scalp, and transmitting the pressure signal to the control system in real time. The adjustment mechanism 6 on the top plate 1 automatically, steplessly, and continuously adjusts the length of the effective section of the connecting strap 4 based on the pressure signal fed back by the pressure sensor 5, thereby achieving closed-loop control of the tightness of the headgear and the electrode fit, ensuring that the detection electrode 3 always maintains a stable, moderate, and uniform fit.

[0039] like Figure 2 , Figure 3 As shown, the adjustment mechanism 6 is the core structure for achieving adaptive size adjustment in this invention. It includes two mutually cooperating strip adjustment plates 7. Several winding shafts 8 are evenly arranged along the length of the adjustment plates 7. The winding shafts 8 are used to support, reverse, and unfold the connecting belt 4. One end of the connecting belt 4 is fixedly connected to the annular belt 2, and the other end extends upward and is continuously wound around the winding shafts 8 of the two adjustment plates 7 in a meandering, interlacing, and reciprocating manner, forming a multi-stage stroke amplification structure. The end of the connecting belt 4 is fixed to one of the adjustment plates 7 to ensure that the winding path is stable, does not slip, and does not loosen.

[0040] The adjustment mechanism 6 is driven by a drive component to change the relative distance between the two adjustment plates 7, thereby changing the unfolded length of the connecting strap 4's winding path. When the two adjustment plates 7 move away from each other, the connecting strap 4 is gradually unfolded and straightened, the effective length is shortened, and the headgear tightens as a whole; when the two adjustment plates 7 move closer to each other, the connecting strap 4 gradually loosens, the effective length is lengthened, and the headgear relaxes as a whole. Through the above structure, the present invention can achieve a large change in the length of the connecting strap with minimal adjustment plate displacement, achieving large-span size adjustment without increasing structural volume or using long-stroke components, fundamentally solving the technical contradiction of "insufficient stroke and bulky structure" in traditional hook and loop fastener structures.

[0041] The drive assembly includes a miniature air pump 9, a diversion solenoid valve 10, an adjustment airbag 11, and a deflation solenoid valve 12. The miniature air pump 9, serving as the power source, is fixedly installed inside the headgear 1, and its output is connected to the diversion solenoid valve 10. The diversion solenoid valve 10 is used to distribute and control multiple gas streams, allowing for simultaneous inflation, independent inflation, or pressure maintenance of multiple adjustment airbags 11. The adjustment airbag 11 is directly positioned between two adjustment plates 7, and its inflation and deflation movement drives the adjustment plates 7. The deflation solenoid valve 12 is installed on the adjustment airbag 11 to achieve precise deflation, slow pressure release, and pressure maintenance, ensuring a smooth, shock-free, and noiseless adjustment process. By controlling the inflation volume of the adjustment airbag 11, the drive assembly continuously and smoothly changes the spacing between the adjustment plates 7, achieving continuous adjustment of the effective length of the connecting strap 4, thereby enabling automated adaptation of the headgear size.

[0042] In a preferred embodiment, the two adjustment plates 7 can be arranged in parallel. One adjustment plate 7 is fixedly connected to the cranial plate 1 to maintain a stable position, while the other adjustment plate 7 is a movable plate that can move horizontally under the influence of the control airbag 11. This structure is simple in layout, easy to assemble, and stable and reliable in operation. It is suitable for adaptive adjustment of most common head circumferences and head shapes, and can meet the basic needs of daily clinical monitoring and home monitoring.

[0043] As another preferred embodiment, one end of the two adjustment plates 7 is connected to each other to form a V-shaped structure. The two adjustment plates 7 are parallel at the corner of the V-shape, forming an installation area for the control airbag 11, ensuring that the control airbag 11 is subjected to uniform force, expands stably, and pushes reliably. The two adjustment plates 7 extend outward at the opening of the V-shape and are respectively provided with a winding shaft 8, one of which extends obliquely upward and the other extends horizontally, making the winding path of the connecting belt 4 more extended and the transition smoother, further improving the stroke amplification effect, expanding the adjustment range, and improving the adjustment sensitivity, making it more suitable for high-precision adaptation of complex head shapes such as irregular heads, flat heads, and protruding occipital bones.

[0044] To further optimize the movement path of the connecting belt 4 and avoid problems such as bending, jamming, twisting, and frictional wear during adjustment, this invention provides a guide roller 13 on the side of the top plate 1. After extending upward from the annular belt loop 2, the connecting belt 4 first passes through the guide roller 13 for reversal and guidance, and then smoothly extends to the winding shaft 8 of the adjustment plate 7. The guide roller 13 can effectively reduce the movement resistance of the connecting belt 4, ensuring smooth adjustment, rapid response, stable operation, and extending the overall service life.

[0045] To further improve adjustment accuracy and achieve a combination of wide-range coarse adjustment and high-precision fine adjustment, this invention provides a short horizontal plate 14 at the installation area of ​​the adjustment plate 7. The short horizontal plate 14 divides the installation area into two independent upper and lower layers, each with its own independent control airbag 11. The adjustment plate 7 is fixedly connected to the cranial plate 1 via the short horizontal plate 14. Sufficient swing space is reserved on both the upper and lower sides of the two adjustment plates 7, allowing them to swing freely within a certain angle. The upper control airbag 11 is used for rapid coarse adjustment, which can significantly change the effective length of the connecting band 4 in a short time to quickly adapt to different head circumferences. The lower control airbag 11 is used for fine fine adjustment, which can slightly correct the electrode contact pressure, accurately match the concave and convex contours of the head, and ensure uniform contact pressure of the detection electrode 3, avoiding local overpressure or local suspension.

[0046] like Figure 4 As shown, to balance wearing comfort and adjustment precision, the connecting strap 4 is designed as a segmented structure. The section of the connecting strap 4 near the annular loop 2 is a low-elasticity loading section 15, and the section near the top plate 1 is a non-elastic wrapping section 16. The detection electrode 3 and pressure sensor 5 are both fixedly mounted on the loading section 15. The low-elasticity loading section 15 provides only a small amount of flexible fit compensation, without generating continuous tension, effectively avoiding problems such as full-area compression, scalp swelling, and poor blood circulation associated with traditional fully elastic headbands. The non-elastic wrapping section 16 has no tensile deformation, ensuring adjustment precision. The effective length of the connecting strap 4 is determined only by the spacing of the adjustment plates 7, unaffected by tensile deformation, ensuring stable, accurate, and reliable adjustment.

[0047] To facilitate disassembly, cleaning, disinfection, and replacement, this invention also includes a separate mounting cloth 17. The mounting cloth 17 completely covers the outside of the loading section 15, and the detection electrode 3 and pressure detection sensor 5 are pre-fixed on the mounting cloth 17 to form a modular detection unit. The mounting cloth 17 can be quickly covered, disassembled, and replaced, facilitating clinical reuse, cleaning, disinfection, and component maintenance, significantly improving the equipment's practicality, hygiene, safety, and reusability.

[0048] Meanwhile, the loading section 15 and the annular belt loop 2 are detachably connected, facilitating the overall disassembly, storage, organization, and maintenance of the headgear. A D-ring buckle 18 is installed on the annular belt loop 2 for manual initial adjustment of its circumference during initial wear, enabling rapid and stable coarse positioning of the headgear. This provides a foundation for subsequent automated fine-tuning, reduces the automatic adjustment stroke, and improves overall adjustment efficiency and response speed.

[0049] In addition, a flexible cushioning pad is provided on the bottom surface of the top plate 1. The flexible pad can further improve the wearing comfort of the top plate. At the same time, detection electrodes can be added according to monitoring needs to expand the EEG monitoring points and improve the comprehensiveness of monitoring and signal quality.

[0050] The complete workflow and automated adjustment process of this invention are as follows:

[0051] In use, the operator first puts the entire headgear on the patient's head, and then tightens the loops appropriately using the D-ring buckle 18 on the loop 2 to complete the initial fixation and coarse positioning of the headgear. This step only requires simple and quick operation and does not require precise adjustment. After the headgear is put on, the pressure detection sensor 5 immediately enters working mode, collecting the contact pressure between the detection electrode 3 and the scalp in real time, and continuously uploading the pressure value to the control system.

[0052] When the pressure sensor 5 detects that the pressure is lower than the preset threshold, the system determines that the detection electrode 3 is not in close contact and there is a risk of it being suspended. Then, it controls the micro air pump 9 to start and inflates the regulating airbag 11 through the diversion solenoid valve 10. The expansion of the regulating airbag 11 pushes the two adjustment plates 7 away from each other, the connecting strap 4 unfolds around the path, the effective length is shortened, and the headgear gradually and smoothly tightens until the detection electrode 3 is completely in close contact with the scalp.

[0053] When the pressure sensor 5 detects that the pressure is within the preset reasonable range, the system determines that the fit is qualified, immediately controls the micro air pump 9 to stop working, closes the diversion solenoid valve 10 and the venting solenoid valve 12, and adjusts the airbag 11 to enter the pressure holding state to maintain the current stable fit.

[0054] When the pressure sensor 5 detects that the pressure is higher than the preset threshold, the system determines that the fit is too tight and there is excessive pressure. It then controls the venting solenoid valve 12 to open, adjusts the airbag 11 to slowly and slightly release air, reduces the spacing of the adjustment plate 7, extends the effective length of the connecting strap 4, and appropriately loosens the headgear until the pressure returns to a reasonable range.

[0055] Throughout the entire EEG monitoring process, the system continuously performs pressure acquisition, signal judgment, and dynamic fine-tuning. It can automatically compensate for fit deviations caused by factors such as patient head rotation, posture changes, and scalp relaxation, and always maintain stable fit, uniform pressure, and reliable contact of the detection electrode 3. This ensures continuous, clear, stable, and accurate EEG signal acquisition, greatly improving monitoring quality and wearing comfort.
