Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a head-mounted adjustable electrode clamping device for treating migraines. Background Technology

[0002] Migraine is the most common type of primary headache in clinical practice, characterized by episodic moderate to severe throbbing headaches, which may be accompanied by nausea, vomiting, and other symptoms. Light, sound, or daily activities can all worsen the headache. While medication is a common treatment, long-term use can lead to dependence and side effects, and it cannot meet the patient's need for immediate relief. In recent years, neurostimulation therapy has received widespread attention as a non-invasive physical therapy method—by stimulating the trigeminal and occipital nerves, which are closely related to migraines, with pulsed currents of specific frequencies, the excitability of the corresponding nerves and blood vessels can be reduced, thereby achieving analgesia and sedation.

[0003] Existing head-mounted migraine treatment devices have the following main shortcomings in use: the adjustment and pressing of the electrode pads usually require the user to complete them step by step, and there is no effective automatic locking mechanism after adjustment. During wear, the electrode pads are prone to displacement due to shaking or touching, causing the stimulation position to deviate from the target nerve area and affecting the treatment effect. At the same time, the operation of wearing the device is relatively cumbersome. Users need to adjust multiple parts separately to complete positioning, fitting, and activation. The process is complicated, especially for patients during a migraine attack, which is a heavy burden. Overall, the existing devices are highly complex to operate and have poor wearing stability, and cannot meet the user's daily life needs. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a head-mounted adjustable electrode clamping device for treating migraines, which solves the problem that the electrode plate position adjustment of existing devices is inconvenient and that the position will shift due to human action.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a head-mounted adjustable electrode clamping device for treating migraines, comprising:

[0006] Wearing body, the wearing body includes a forehead support part for fitting against the forehead of the user's head, a back head support part for fitting against the occipital bone protrusion of the back of the user's head, and a combined connecting strap for connecting the forehead support part and the back head support part;

[0007] Two connecting slots are provided on both sides of the forehead support part, and two fixing posts are fixedly connected in the connecting slots. Two hanging ears are fixedly connected on both sides of the back of the head support part, and the center of the hanging ears is hollowed out.

[0008] The combined connecting strap includes silicone branch straps fitted onto the fixed post. Four branch straps on one side of the forehead support are fixedly connected to elastic bands. Two leather extension straps are fixedly connected to the other side of the elastic bands. The other ends of the two extension straps are fixedly connected to connecting buckles. A rope buckle is rotatably connected to the connecting buckle. Two fabric ropes are movably connected to the rope buckle. Ring hooks are movably connected to the ear loops on both sides of the back of the head support. The ring hooks are connected to the two fabric ropes on the corresponding side by a D-ring buckle.

[0009] As a further aspect of the present invention: the two branch bands in the connecting groove have slightly different lengths, with the branch band on the front of the forehead bearing section being longer than the other branch band. The elastic band is made of fabric, and several elastic airbags are evenly distributed along its length on the extension band. When worn, this reduces the contact area with the user's head and avoids heat accumulation while providing cushioning.

[0010] As a further embodiment of the present invention: the forehead support portion is an annular frame-shaped plastic shell, and the inner top and inner bottom surfaces of its spiral groove are provided with sliding grooves. Two pairs of opposing arc-shaped support seats are fixedly connected to the back of the forehead support portion for supporting and fitting the user's forehead. An arc-shaped groove is provided at the center of the back of the forehead support portion, which can also fit the user's forehead and avoid poor contact. An electrode adjustment assembly is slidably connected inside the forehead support portion.

[0011] As a further aspect of the present invention: the electrode adjustment assembly includes an adjustment housing disposed within the forehead support portion. The top and bottom of the adjustment housing are fixedly connected to slide rails that match the slide groove. An annular groove is formed inside the adjustment housing, and a matching annular support airbag is installed in the annular groove. A support plate is slidably connected to the adjustment housing at the center of the annular groove. Three electrode plates are installed on the support plate. Two piston-type air pumps are fixedly connected to the adjustment housing. The output end of the piston-type air pump is directly opposite the bottom of the support plate. After the annular support airbag is inflated, it can provide stable support for the trigeminal nerve position on the user's forehead.

[0012] As a further aspect of the present invention: two symmetrically arranged receiving slots are provided on the forehead support part, and a winding reel is connected to the receiving slot through a coil spring. A PU tube is wound on the winding reel. One end of the PU tube passes through the forehead support part, the adjusting shell and communicates with the annular support airbag. When the electrode adjusting component slides in the forehead support part, the PU tubes on both sides are wound and unwound through the winding reel. The setting of the coil spring can ensure that the tube is always taut.

[0013] As a further aspect of the present invention: a guide groove is provided on the front of the adjusting shell, and three pressure relief valves are designed in the guide groove. The pressure relief valves are connected to the annular support airbag in the annular groove on the back of the guide groove. Two of the pressure relief valves are connected to the piston-type air pump through pipes, and a piston box is fitted on the other pressure relief valve. The piston box is fixedly connected in the guide groove, and a piston plate is slidably connected in the piston box. A button switch is fixedly connected to the top of the piston box. The annular support airbag is inflated through the PU tube. After the annular support airbag is fully inflated, the pressure relief valve guides the remaining gas to the piston-type air pump and the piston box to lift the support plate so that the electrode pair fits against the user's forehead.

[0014] As a further aspect of the present invention: strip-shaped notches are provided on both sides of the adjusting shell corresponding to the annular groove positions, and auxiliary airbags are provided on both sides of the annular support airbag corresponding to the positions. After the annular support airbag is inflated, the auxiliary airbags expand synchronously. Friction pads are attached to both the outside of the auxiliary airbags and the inner wall of the U-shaped groove of the forehead bearing part. After the auxiliary airbags expand, the friction pads are attached, which can further lock the position of the electrode adjusting assembly and prevent the adjusting shell from shifting.

[0015] As a further embodiment of the present invention: the posterior head support includes a wing-shaped frame plate, two electrode plates, and an annular locking airbag. The two sides of the wing-shaped frame plate are fixedly connected to the ear loops. The two electrode plates are symmetrically arranged on the wing-shaped frame plate. The annular locking airbag is fixedly connected to the center of the wing-shaped frame plate. The annular locking airbag can lock the occipital bone protrusion of the user's head.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This invention establishes a specialized airflow path through a pressure relief valve. During inflation, gas preferentially enters the annular support airbag to provide flexible positioning support for the forehead area. After the airbag inflates to the set pressure, a sequential diversion valve automatically switches the air path, directing subsequent gas to the piston-type air pump and piston box, which respectively drive the electrode pads to lift and adhere, and trigger the electrical stimulation activation signal. Users only need to complete the single operation of inflation to automatically complete the entire process of positioning, adhesion, and activation, significantly reducing operational difficulty and improving ease of use.

[0018] 2. This invention, based on the ability to fine-tune the electrode pads, automatically presses the friction pads against the inner wall of the housing through the synchronous expansion of the auxiliary airbag and the annular support airbag, achieving instant locking of the adjusted position. This locking method requires no additional operation from the user, and the locking force increases with the inflation pressure, effectively preventing the electrode pads from shifting due to shaking or contact during wear, ensuring the continuous and accurate application of electrical stimulation to the target nerve area.

[0019] 3. This invention achieves differentiated adaptation to different user environments through the initial positioning of the forehead arc support, the embracing fixation of the occipital protrusion by the ring-shaped locking airbag at the back of the head, and the ventilation gap formed by the elastic airbag on the extension band, effectively reducing local pressure and stuffiness. Simultaneously, the forehead support and the back of the head support are tensioned by a combined connecting band to form a coordinated overall constraint, maintaining a stable wearing position for various head sizes and providing structural assurance for continuous and precise stimulation of the electrode pads.

[0029] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0030] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a head-mounted adjustable electrode clamping device for treating migraines. It mainly consists of a forehead support part 2 and a back-head support part 3. It can electrically stimulate the trigeminal nerve in the user's forehead and the occipital nerve region in the back of the head to treat migraines. It includes: a wearing body 1, which includes a forehead support part 2 for fitting against the user's forehead, a back-head support part 3 for fitting against the occipital bone protrusion in the back of the user's head, and a combined connecting strap 4 for connecting the forehead support part 2 and the back-head support part 3.

[0031] The frontal support section 2 and the posterior head support section 3 are divided into zones corresponding to the stimulation areas of the trigeminal nerve and the occipital nerve, respectively. The combined connecting band 4 is made of various materials and can be adapted to users with different head circumferences.

[0032] Two connecting slots 5 are provided on both sides of the forehead support part 2, and two fixing posts are fixedly connected in the connecting slots 5. Two hanging ears 6 are fixedly connected on both sides of the back of the head support part 3, and the center of the hanging ears 6 is hollowed out.

[0033] The combined connecting strap 4 includes silicone branch straps 41 sleeved on the fixed post. Four branch straps 41 on one side of the forehead support 2 are fixedly connected to elastic bands 42. Two leather extension straps 43 are fixedly connected to the other side of the elastic bands 42. The other ends of the two extension straps 43 are fixedly connected to connecting buckles 44. A cord buckle 45 is rotatably connected to the connecting buckle 44. Two fabric cords 46 are movably connected to the cord buckle 45. Ring hooks 47 are movably connected to the ear loops 6 on both sides of the back of the head support 3. The ring hooks 47 are connected to the two fabric cords 46 on the corresponding side by a D-ring buckle. The lengths of the two branch straps 41 in the connecting groove 5 are slightly different. The branch strap 41 on the front of the forehead support 2 is longer than the other branch strap 41. The elastic bands 42 are made of fabric. Several elastic airbags are evenly distributed along the length of the extension straps 43. When worn, the contact area with the user's head is reduced, and heat accumulation is avoided on the basis of cushioning.

[0034] The combined connecting strap 4 is composed of a multi-level structure consisting of branch strap 41, elastic strap 42, extension strap 43, fabric rope 46, and D-ring buckle. The elastic strap 42 can be extended to achieve changes in the length of the overall structure. The extension strap 43 is longer and fits the side area of ​​the user's head. The elastic airbag on it has a certain cushioning effect and, compared to when it is not set, the contact area with the user's head is smaller, which can prevent sweating.

[0035] Example 2, refer to Figures 4-8This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a head-mounted adjustable electrode clamping device for treating migraines and a detailed description of its forehead support part 2. The forehead support part 2, as the main structure, can electrically stimulate the trigeminal nerve area of ​​the user's forehead to relieve migraine symptoms. It includes: the forehead support part 2 is an annular frame-shaped plastic shell, with sliding grooves on the inner top and bottom surfaces of its spiral groove; two pairs of opposing arc-shaped support seats 7 are fixedly connected to the back of the forehead support part 2 for supporting and fitting the user's forehead; an arc-shaped groove is provided at the center of the back of the forehead support part 2, which can also fit the user's forehead and avoid poor contact; and an electrode adjustment assembly 8 is slidably connected inside the forehead support part 2.

[0036] The forehead support 2 adopts a ring-shaped plastic shell. The grooves on its inner top and bottom surfaces provide guidance for the horizontal sliding of the electrode adjustment assembly 8, allowing the electrode plate 86 to be finely adjusted in the trigeminal nerve region. The arc support 7 and the arc groove can form a three-point or multi-point support structure, corresponding to the two sides of the user's forehead and the glabella area, respectively, which can provide a basic positioning effect for wearing this device.

[0037] The electrode adjustment assembly 8 includes an adjustment housing 81 disposed within the forehead support portion 2. The top and bottom of the adjustment housing 81 are fixedly connected to slide rails 82 that match the slide grooves. An annular groove 83 is formed inside the adjustment housing 81, and a matching annular support airbag 84 is installed in the annular groove 83. A support plate 85 is slidably connected to the adjustment housing 81 at the center of the annular groove 83. Three electrode plates 86 are installed on the support plate 85. Two piston-type air pumps 87 are fixedly connected to the adjustment housing 81. The output end of the piston-type air pump 87 faces the bottom of the support plate 85. After the annular support airbag 84 is inflated, it can provide stable support for the trigeminal nerve position on the user's forehead.

[0038] The adjustable shell 81 can slide as a whole relative to the forehead support 2. The user can slide the adjustable shell 81 to the trigeminal nerve position to achieve fine adjustment. After the annular support airbag 84 is inflated, it can increase the pressure between the user's skin to increase friction and avoid positional displacement caused by changes in the user's posture or other movements. The support plate 85 is located in the central area of ​​the annular support airbag 84. After being lifted by the piston air pump 87, the three electrode plates 86 on it can fit in place with the trigeminal nerve position.

[0039] Two symmetrical receiving slots 9 are provided on the forehead support part 2. A winding reel 10 is connected to the receiving slot 9 through a coil spring. A PU tube is wound on the winding reel 10. One end of the PU tube passes through the forehead support part 2, the adjusting shell 81 and communicates with the annular support airbag 84. When the electrode adjusting component 8 slides in the forehead support part 2, the PU tubes on both sides are wound and unwound through the winding reel 10. The setting of the coil spring can ensure that the tube is always taut.

[0040] The front of the adjusting housing 81 has a guide groove 11, and three pressure relief valves 12 are designed in the guide groove 11. The pressure relief valves 12 are connected to the annular support airbag 84 in the annular groove 83 on the back of the guide groove 11. Two of the pressure relief valves 12 are connected to the piston-type air pump 87 through pipes. The other pressure relief valve 12 is fitted with a piston box 13, which is fixedly connected in the guide groove 11. A piston plate 14 is slidably connected in the piston box 13. A push-button switch 15 is fixedly connected to the top of the piston box 13. The annular support airbag 84 is inflated through the PU tube. After the annular support airbag 84 is fully inflated, the pressure relief valve 12 guides the remaining gas to the piston-type air pump 87 and the piston box 13 to lift the support plate 85 so that the electrode plate 86 fits against the user's forehead.

[0041] A miniature air pump (not shown in the figure) pressurized via a PU tube is installed inside the forehead support section 2. It first pressurizes the annular support airbag 84 through the PU tube. After the annular support airbag 84 is fully inflated, the pressure relief valve 12 at its bottom is not a traditional safety release valve, but a pressure sequence valve. When the air pressure inside the annular support airbag 84 reaches a preset threshold, the valve automatically opens, guiding the subsequent gas to the piston-type air pump 87 and piston box 13. The push-button switch 15 is electrically connected to each electrode plate. When the push-button switch 15 is turned on, each electrode plate is energized. The entire device automatically completes the process in the sequence of first supporting, then lifting, and then energizing, without requiring additional user operation, thus improving ease of use.

[0042] The two sides of the adjusting housing 81 are provided with strip-shaped notches corresponding to the positions of the annular groove 83. The two sides of the annular support airbag 84 are provided with auxiliary airbags 16 corresponding to the positions. After the annular support airbag 84 is inflated, the auxiliary airbags 16 expand synchronously. Friction pads 17 are attached to the outside of the auxiliary airbags 16 and the inner wall of the U-shaped groove of the forehead support part 2. After the auxiliary airbags 16 expand, the friction pads 17 are attached, which can further lock the position of the electrode adjusting assembly 8 and prevent the adjusting housing 81 from shifting.

[0043] After the secondary airbag 16 expands with the annular support airbag 84, the secondary airbag 16 will extend partially from the strip-shaped notch, pressing the friction pad 17 that is attached to the outside of the secondary airbag 16 against the inner wall of the U-shaped groove of the forehead support part 2, thereby achieving friction locking of the position of the electrode adjustment component 8 and avoiding displacement of the electrode pad due to shaking or touching during wearing.

[0044] The rest of the structure is the same as in Example 1.

[0045] Example 3, referring to Figures 1-2 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a description of a head-mounted adjustable electrode clamping device for treating migraines and its posterior head support part 3. The posterior head support part 3 includes a wing-shaped frame plate 31, two electrode plates 32, and an annular locking airbag 33. The two sides of the wing-shaped frame plate 31 are fixedly connected to the ear loops 6. The two electrode plates 32 are symmetrically arranged on the wing-shaped frame plate 31. The annular locking airbag 33 is fixedly connected to the center of the wing-shaped frame plate 31. The annular locking airbag 33 can lock the occipital bone protrusion of the user's head.

[0046] When wearing this device, the annular locking airbag 33 needs to be aligned with the occipital protuberance (i.e., external occipital protuberance) at the back of the user's head to form an environmentally friendly mechanical locking effect. This locks the back of the head support 3 in the occipital nerve area to prevent displacement. It can also work in tandem with the electrode adjustment component 8 of the aforementioned forehead support 2. The forehead is initially positioned by the arc-shaped support seat 7, the electrode adjustment component 8 is locked by the airbag friction pad, and the back of the head is held in place by the annular locking airbag 33. Together, they ensure the positional stability of the entire wearer on the head and provide structural protection for the electrode pads to continuously and accurately stimulate the target nerves.

[0047] The rest of the structure is the same as in Example 2.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
