Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment or electronic equipment, in particular to a wearable device for treating or preventing headache. BACKGROUND

[0002] Migraine is a type of headache. At present, the main method for treating migraine is drug treatment. However, due to side effects and limited efficacy, drug treatment cannot meet the needs of a large number of patients with headache. Wearable headache treatment instruments have emerged as the times require.

[0003] The wearable headache treatment instrument can achieve analgesic treatment and long-term preventive effect on migraine by providing electrical stimulation to the human nervous system to trigger the conditioned pain modulation (CPM) mechanism. The conditioned pain modulation is an endogenous pain inhibition mechanism, which refers to the phenomenon that the persistent pain in a part of the body can inhibit the pain perception caused by the nociceptive stimulation in another part of the body, that is, "pain relieving pain".

[0004] The headache treatment instrument includes an external trigeminal nerve stimulation device. When in use, the external trigeminal nerve stimulation device is worn on the head or forehead. The external trigeminal nerve stimulation device stimulates the trigeminal nerve by generating an electric current, thereby relieving headache, and is suitable for relieving dizziness, car sickness and other head discomfort. Since the stimulation site is close to the brain, common adverse reactions such as drowsiness, fatigue and insomnia may occur. However, the instrument must be used in a resting state, and must be continuously worn on the forehead when in use, which is very inconvenient in public places. In addition, it is also very inconvenient to carry out.

[0005] The headache treatment instrument also includes a remote electrical neuromodulation instrument. When in use, the patient first fully exposes the upper arm, then binds the instrument on the upper arm, and then controls the instrument to release an electric pulse to stimulate the sensory nerve C fiber transmitting to the pain center, thereby achieving a treatment effect. Since the stimulation site is far away from the head, the sensory nerve C fiber has a slow nerve conduction speed, and the treatment requires a long time and has a slow onset speed. Long-term stimulation may cause local skin tingling and hypersensitivity and other side effects. At the same time, the instrument also needs to be used in a resting state, and needs to expose the upper arm, which is very inconvenient in public places. In addition, it is also very inconvenient to carry out.

[0006] The headache treatment instrument also includes a wrist-type headache treatment instrument, which can be worn on the wrist by the patient daily, used anytime and anywhere, and is light and easy to carry. Moreover, the wrist-type wearable device has a strong concealment due to its appearance similar to a watch or bracelet, and does not attract the attention of others when used in public, thereby benefiting the protection of the privacy of the patient. Compared with the above two treatment methods, although the treatment instrument is farthest from the head, it can directly and accurately stimulate the main stem of the wrist nerve, has a fast transmission speed and high efficiency, and can exert a rapid analgesic effect. However, since the CPM mechanism needs to be triggered to achieve the effect of treating headaches, the reactivity will differ among different people due to the sensitivity of the CPM mechanism.

[0007] The incidence of headache patients is usually high, for example, the frequency of migraine attacks is up to 30 times per month, and the frequency of cluster headaches is up to 8 times per day. The patient can switch between private places and public places every day, and any of the above headache treatment instruments cannot meet the needs of the patient to freely select the stimulation site according to the use occasion, and it is not only costly but also inconvenient to carry two or more headache treatment instruments every day.

[0008] Therefore, the headache treatment instrument in the prior art cannot meet the needs of the patient in various use scenarios. Content of the utility model

[0051] Embodiments of the present application are directed to a wearable device for treating or preventing headache, which is used to solve the technical problem that the existing headache treatment instrument cannot meet the needs of patients in various use scenarios.

[0052] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments of the present application are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments and the embodiments of the present application can be combined with each other.

[0053] Figures 1-11 A wearable device for treating or preventing headache (including migraine, cluster headache, tension-type headache, and other types of headache or head discomfort such as car sickness and dizziness) according to an embodiment of the present application is shown, which can be worn on the wrist, head or upper arm of a patient, and achieves the effect of treating or preventing headache by electrically stimulating the wrist nerve (in the present application, it refers to the median nerve and / or ulnar nerve) on the ventral side of the wrist, the frontal nerve (in the present application, it refers to the supraorbital nerve and / or supra-trochlear nerve) on the head or the sensory nerve C fiber on the upper arm, especially suitable for migraine.

[0054] Since the wearable device can be worn on one of the wrist, head or upper arm, it can be worn on the head or upper arm when the patient is in a private space and does not need to worry about being noticed by others; it can be worn on the head when the patient does not need to worry about being noticed by others and it is more troublesome to expose the upper arm; it can be worn on the wrist when the patient does not want to attract the attention of others in a public place or the wearable device is in a non-stimulating treatment state. In this way, the wearing position of the wearable device can be flexibly selected, which can meet the needs of patients in various use scenarios, and is convenient for daily carrying. The present application aims to improve the convenience of using the headache treatment instrument and provide users with more choices.

[0055] It should be noted that the median nerve and the ulnar nerve are two main nerves of the upper limb, which respectively innervate different muscles and sensory areas; for the convenience of wearing, the wearable device described in the embodiments of the present application acts on the median nerve area and / or the ulnar nerve area on the inner side of the wrist.

[0056] The supraorbital nerve and the supra-trochlear nerve are two branches of the first branch of the trigeminal nerve, the ophthalmic nerve, which pass out above the superior margin of the orbital rim and distribute to the mucosa of the frontal sinus, the conjunctiva and skin of the upper eyelid, the skin of the forehead, and the scalp; for the convenience of wearing, the wearable device described in the embodiments of the present application acts on the supraorbital nerve and / or the supra-trochlear nerve area of the forehead.

[0057] The sensory nerve C fiber is a kind of nerve fiber in the peripheral nervous system, which is mainly responsible for transmitting pain, temperature and other non-obvious touch information; for the convenience of wearing, the wearable device described in the embodiments of the present application mainly acts on the sensory nerve C fiber innervation area on the inner side of the upper arm.

[0058] As shown in Figures 1-11 , the wearable device comprises a stimulator 100 and a flexible fixing member connected with the stimulator 100, the flexible fixing member can fix the stimulator 100 on the wrist, the head or the upper arm, so that the stimulator 100 is attached to the wrist nerve, the forehead nerve of the head or the sensory nerve C fiber of the upper arm.

[0059] As shown in Figures 1-8 , the stimulator 100 comprises a shell, the cross-sectional shape of the shell can be any shape such as square, rectangle, circle, etc., the shell is used to set and protect the internal elements (such as pulse generator, power supply, controller, communication components, etc.) located in the shell and to set the external elements (such as display screen 150, data / power port 130, switch button 110, intensity adjustment key 120, etc.) exposed on the outer wall of the shell.

[0060] The pulse generator is electrically connected with the power supply to form an electric pulse. The pulse generator is electrically connected with the controller for executing control instructions, the controller is connected with the pulse generator signal, and the controller can control the start and stop of the pulse generator and generate an electric pulse with a predetermined time length, a predetermined frequency and a predetermined width according to the control instructions input by the user.

[0061] For example, the pulse generator provides an electric pulse frequency of 40-100 Hz, an electric pulse width of 300 μs, and an electric current intensity of 10-30 mA, wherein the electric current intensity for children is 10-15 mA and the electric current intensity for adults is 15-30 mA. The electric pulse with the above parameters can achieve a safe and effective treatment with less side effects and high tolerance. Of course, the wearable device can also be treated according to other working modes or working parameters, which are not limited herein.

[0062] The communication component is used to connect the controller and an external terminal device (such as a mobile phone, a tablet, a computer, etc.) to realize the communication between the external terminal device and the wearable device. For example, the controller can communicate with the external computing device through the communication component (such as wireless communication) to update the software and / or parameters and / or read data. For another example, the working parameters of the wearable device are obtained on the external terminal device based on the communication component, or the wearable device is controlled by inputting a control instruction through the external terminal device.

[0063] The wearable device described in the embodiments of the present application can be used independently. For example, one or more buttons, a display screen 150, a dial and / or a keyboard are arranged on the shell for a user to input a control instruction. The display screen 150 (touch display screen 150), the buttons, the dial and / or the keyboard are in communication connection with the controller and can be used by the user to input a control instruction. The display screen 150 can display the working state feedback of the wearable device described in the embodiments of the present application to the user, and can also be used by the user to view the display content of other functions, such as time, weather, heart rate, sleep state, blood pressure, oxygen saturation, etc.

[0064] The wearable device described in the embodiments of the present application can also be applied in combination with other smart devices, which can be a personal computer, a notebook computer, a smart phone, a tablet computer, a smart speaker, a smart television, a smart vehicle device, etc. The smart device has an application program that allows communication with the wearable device and acts as a controller.

[0065] Of course, in some embodiments, the wearable device described in the embodiments of the present application can be integrated with a smart watch, such as an Apple watch or an Android-based smart watch. The smart watch provides a watchband as a flexible fixing member and a watch dial as a stimulator 100 for the wearable device.

[0066] The power source can be a disposable dry cell battery, a rechargeable battery, or a combination of both. Disposable batteries are replaceable, while rechargeable batteries require a reserved charging interface. For example, in some embodiments, the wearable device may have a data / power port 130, such as a USB port, which allows the user to charge the power source, update the software and / or parameters on the microcontroller, and / or read data from the controller's storage unit. The controller can communicate with an external computing device through the data port to update software and / or parameters and / or read data.

[0067] In addition, to facilitate quick operation by the user, a switch button 110 can be provided on one side of the wearable device. The switch button 110 is connected to the controller, so that the user can quickly start or stop the stimulator 100.

[0068] In addition, to facilitate users in adjusting the intensity of electrical stimulation, an intensity adjustment key 120 can be provided on one side of the wearable device. The intensity adjustment key 120 is connected to the controller, so that users can input control commands to the controller. The controller generates electrical pulses of a predetermined frequency and width based on the control commands, thereby adjusting the intensity of electrical stimulation. However, the principle and implementation of adjusting the intensity of electrical stimulation through the intensity adjustment key 120 can refer to the existing technology.

[0069] like Figures 1-5 As shown, a first electrode 300 is also fixed on the back of the outer casing. The inner end of the first electrode 300 is electrically connected to the pulse generator, and the outer end is exposed outside the outer casing to contact the wrist nerve on the wrist.

[0070] The first electrode 300 includes at least one group, each group of first electrodes 300 including at least one first electrode 300 used as an anode and at least one first electrode 300 used as a cathode, and the anode and cathode in the group are respectively used to target different locations of the wrist nerve (different locations of the same wrist nerve or different wrist nerves); when the anode and cathode in the group simultaneously contact and conduct with different locations of the wrist nerve, the anode, the cathode, the wrist nerve, and the pulse generator are electrically connected to form a conductive path, thereby providing electrical stimulation to the wrist nerve.

[0071] For example, in one embodiment of this application, such as Figures 2-4 As shown, the first electrode 300 includes a group of two first electrodes 300 that can be spaced apart along the length of the wrist nerve (e.g., along the length of the median nerve). One of the first electrodes 300 is used as an anode and the other is used as a cathode. When the anode and cathode simultaneously contact and conduct with different parts of the median nerve or ulnar nerve, or when the anode and cathode contact and conduct with the median nerve and ulnar nerve respectively, the anode, cathode, wrist nerve, and pulse generator are electrically connected to form a conductive path.

[0072] The electric pulse provides electric stimulation to the median nerve and / or the ulnar nerve on the wrist through the first electrode 300, and the electric pulse formed by the stimulator 100 is conducted to the pathway formed by the "wrist median nerve (or ulnar nerve)-spinal nerve-trigeminal nerve cervical complex-thalamus-cerebral cortex" in turn, which has a common integrated center (i.e. thalamus) and a common collection end point (i.e. cerebral cortex) with the nerve conduction pathway of headache (formed by "trigeminal nerve-trigeminal nucleus-brainstem trigeminal tract-thalamus-cerebral cortex" in turn). Therefore, by stimulating the median nerve and / or the ulnar nerve on the wrist, the conditioned pain modulation mechanism is triggered, so as to achieve the analgesic treatment and long-term prevention of migraine, significantly improve the disease burden of patients with headache, and improve the quality of life.

[0073] Due to the appearance of the wrist-worn device similar to a watch or a bracelet, the patient wears it on the wrist in daily life, like a common watch. The stimulator 100 is located on the dorsal side of the wrist, and when it is needed to be used for treatment and prevention of headache, the stimulator 100 is moved to the ventral side of the wrist, and the stimulator 100 is turned on, which is convenient to use, can be used anytime and anywhere, is light and easy to carry, has good concealment, and is convenient for privacy protection of the patient.

[0074] Of course, in the above embodiment, any anode can also be provided with 2 or more first electrodes 300, and any cathode can also be provided with 2 or more first electrodes 300, so as to enhance the conduction efficiency and improve the stimulation effect.

[0075] The second electrode 400 is a flexible electrode, and the second electrode 400 is detachably connected with the first electrode 300, that is, the second electrode 400 is in communication with the stimulator 100 through the first electrode 300. In this way, when acting on the wrist, the second electrode 400 can be detached, and when acting on the head or the upper arm, the second electrode 400 can be assembled, so that the space utilization rate is higher, and the whole is more compact and small. Of course, the second electrode 400 can also be directly detachably connected with the shell of the stimulator 100, and the first electrode 300 and the second electrode 400 are switched in communication with the stimulator 100 through a switch, so as to achieve the effect of selective use of the first electrode 300 and the second electrode 400, which is not limited herein.

[0076] In addition, the flexible electrode has the characteristics of bendability, foldability and ductility, has high skin friendliness, has a planar structure and has no point resistance, and thus has high comfort in use. In addition, the flexible electrode can be replaced after being worn or damaged, and a new flexible electrode can be replaced in time when the conductive performance of the flexible electrode is reduced, so that the use safety is improved, the overall service life of the stimulator 100 is prolonged, and the overall use cost is reduced. At the same time, since the attack of migraine is intermittent, the electric stimulation function can be turned off and the flexible electrode can be removed and stored when the electric stimulation function is not needed during the attack of migraine, so that unnecessary wear is reduced, the service life of the flexible electrode is prolonged, and the use cost is further reduced.

[0077] For example, in an embodiment of the present application, the flexible electrode is buckled to the first electrode 300, and is very convenient to assemble and disassemble.

[0078] Specifically, one buckle groove 310 is fixedly arranged on each of the two first electrodes 300, the buckle groove 310 is electrically connected to the pulse generator, the flexible electrode is provided with a clamping column 410 which can be buckled to the buckle groove 310, the clamping column 410 is electrically connected to the flexible electrode, and the clamping column 410 and the buckle groove 310 belong to a connecting structure.

[0079] The buckle groove 310 and the clamping column 410 are made of conductive materials, such as copper and aluminum. When the clamping column 410 is buckled into the buckle groove 310, the flexible electrode is fixed on the shell and is in conduction with the pulse generator. When the clamping column 410 is pulled out of the buckle groove 310, the flexible electrode is separated from the shell, and the flexible electrode can be replaced. The conductive buckle groove 310 and the clamping column 410 can not only realize the detachable connection between the flexible electrode and the stimulator 100 in a physical way, but also realize the electrical connection between the flexible electrode and the stimulator 100, so that the overall structure is compact.

[0080] In addition, the buckle groove 310 is arranged on the first electrode 300, and the buckle groove 310 is recessed in the first electrode 300 or the outer surface of the buckle groove 310 is flush with or substantially flush with the outer surface of the first electrode 300. When the flexible electrode is buckled on the first electrode 300, the overall flatness can be ensured, so that the flexible electrode can be fully aligned and contacted with the target nerve, the electric stimulation effect of the second electrode 400 is ensured, and after the flexible electrode is removed, the smoothness of the surface of the first electrode 300 in contact with the skin is ensured, so that the comfort of wearing the wrist-worn device after the flexible electrode is removed is improved.

[0081] When the wearable device is worn on the head, the electric pulse is transmitted to the frontal nerve through the second electrode 320, and when the frontal nerve converges into the trigeminal nerve, the electric pulse transmitted to the trigeminal nucleus is directly electrically stimulated and regulated, thereby directly regulating the excitability of the trigeminal nucleus group during a migraine attack, and achieving the effect of inhibiting the migraine attack.

[0082] Similarly, when the wearable device is worn on the upper arm, the electric pulse is transmitted to the pain C-fiber in the upper arm nerve through the second electrode 320, and the pain signal caused by the electric stimulation is transmitted upward to the pain center of the thalamus and cerebral cortex, and finally triggers the endogenous pain inhibition mechanism-conditional pain modulation (CPM) effect, thereby achieving the effect of analgesic treatment for migraine.

[0083] Of course, the buckle slot 310 can also be directly provided on the shell, for example, the buckle slot 310 is provided on the shell between the two first electrodes 300, and the buckle slot 310 is directly electrically connected with the pulse generator, that is, the flexible electrode is directly electrically connected with the pulse generator through the buckle slot 310 and the clamping column 410.

[0084] Of course, the flexible electrode can also be detachably connected with the stimulator in other ways, such as threaded connection, etc., for example, a threaded connection hole is provided on the shell or the first electrode 300, and a threaded connection column is provided on the flexible electrode, the flexible electrode is fixed by screwing the threaded connection column and the threaded connection hole, and the threaded connection column and the threaded connection hole are made of conductive material, which can realize the electrical connection between the flexible electrode and the pulse generator.

[0085] Of course, the second electrode can also be other electrodes, such as metal electrodes, etc., which are not limited herein.

[0086] Further, the two ends of the clamping column 410 are clamped and fixed on the front and back surfaces of the flexible electrode.

[0087] Among them, the bottom end of the clamping column 410 penetrates through the flexible electrode, and the bottom end of the clamping column 410 is respectively provided with a front piece and a back piece for clamping the front and back surfaces of the flexible electrode, and the front piece and the back piece are fixedly connected with the clamping column 410, so that the clamping column 410 and the flexible electrode are integrated.

[0088] In addition to the electrical connection between the clamping column 410 and the flexible electrode, the front piece and the back piece are also conductive and electrically connected with the clamping column 410, thereby enhancing the connection effect between the clamping column 410 and the flexible electrode, and the front piece and the back piece increase the contact surface with the flexible electrode, thereby improving the physical fixing strength of the clamping column 410 on the flexible electrode.

[0089] Further, at least one side edge of the flexible electrode exceeds the corresponding back sheet, so as to avoid the back sheet covering the flexible electrode and affecting the stimulation effect.

[0090] Generally, the circumference of the wrist of an adult is 13-20 cm, the circumference of the head is 54-58 cm, and the circumference of the upper arm is 20-35 cm. The wearable device of the embodiment of the present application is to be worn on the head, the upper arm, and the wrist, which have large differences in circumference. Therefore, the flexible fixing member must have good adaptability and / or adjustability. The flexibility of the flexible fixing member refers to the ability to change shape according to the human body part, so as to better fit the wrist, the head, or the upper arm.

[0091] For example, in an embodiment of the present application, as shown in Figures 9-11 the flexible fixing member is an adhesive band 230 arranged around the stimulator. The back of the adhesive band 230 is adhesive and can be adhered and fixed on the wrist, the head, or the upper arm. The adhesive fixing has strong adaptability and does not need to consider the dimensional differences of the head, the upper arm, and the wrist. In addition, the adhesive band 230 itself has flexibility and can well fit the curvature of the wrist, the head, or the upper arm, so as to effectively fix the stimulator on the stimulation site.

[0092] Further, the adhesive band 230 is arranged on both sides of the stimulator 100, so as to adhere and fix the stimulator 100 on the wrist, the head, or the upper arm from both sides, has good fixing effect, and can reduce the adhesive area and improve the wearing comfort. Of course, the adhesive band 230 can also be arranged in two pairs or more pairs, or arranged in a whole circle along the outer periphery of the stimulator 100, so as to enhance the fixing effect.

[0093] Further, the adhesive band 230 is a silicone gel, which can be reliably pasted on the skin, is convenient to remove and reposition, does not cause harm to the skin, does not cause discomfort due to pasting, and can be repeatedly pasted and used.

[0094] In addition, in order to facilitate the replacement of the adhesive band 230, the adhesive band 230 is detachably connected with the back of the stimulator 100. For example, a Velcro hook surface is arranged on the back of the shell of the stimulator 100, and a Velcro loop surface is arranged on the adhesive band 230. The stimulator 100 and the adhesive band 230 are detachably connected through the Velcro adhesion. In addition, a window exposing the first electrode 300 is arranged on the adhesive band 230, and the first electrode 300 passes through the window, so as to not affect the contact of the first electrode 300 with the wrist nerve.

[0095] In another embodiment of the present application, as shown in Figures 1-4As shown, the flexible fixing member is a flexible band, such as a silica gel band, a leather band, or a nylon woven band, etc. The flexible band can form a ring structure with adjustable circumference, and the circumference of the ring structure can be locked to be tightly fitted on the wrist, the head, or the upper arm, so as to bind the stimulator 100 on the wrist, the head, or the upper arm. In this way, the ring structure can be adjusted to adapt to the wrist, the head, or the upper arm with different sizes. For example, the circumference of the ring structure can range from 10 cm to 65 cm to cover the wrist circumference, the head circumference, and the upper arm circumference of an ordinary person.

[0096] The flexible band includes a first band body 210 and a second band body 220 arranged oppositely on both sides of the stimulator 100. The inner end of the first band body 210 and the inner end of the second band body 220 are connected to the stimulator 100 respectively. The first band body 210 and the second band body 220 can form a ring structure to be tightly fitted on the wrist, the head, or the upper arm. The circumference of the ring structure can be adjusted and locked.

[0097] For example, the front surface of the first band body 210 and the front surface of the second band body 220 are Velcro fluffs respectively. The back surface of the outer end of the second band body 220 is provided with a Velcro hook 222 which can be adhered and fixed with the Velcro fluff. In this way, when the Velcro hook 222 on the second band body 220 is adhered with the Velcro fluff on the front surface of the first band body 210 or the Velcro fluff on the front surface of the second band body 220 is adhered, a ring structure with different sizes is formed to adapt to the wrist, the head, or the upper arm.

[0098] When the wearable device is worn on the head, the stimulator 100 is aligned with the frontal nerve, and the first band body 210 and the second band body 220 are wound along the head. The second band body 220 is pulled tight, and the Velcro hook 222 on the back surface of the second band body 220 is adhered with the Velcro fluff, so that the first band body 210 and the second band body 220 form a ring structure which can be bound and fixed on the head. Since the head is large, the Velcro hook 222 on the back surface of the second band body 220 is adhered with the Velcro fluff on the first band body 210.

[0099] When the wearable device is worn on the wrist, the stimulator 100 is aligned with the wrist nerve, and the first band body 210 and the second band body 220 are wound along the wrist. The second band body 220 is pulled tight, and the Velcro hook 222 on the back surface of the second band body 220 is adhered with the Velcro fluff, so that the first band body 210 and the second band body 220 form a ring structure which can be bound and fixed on the wrist. Since the wrist is thin, the second band body 220 can be wound on the wrist for multiple times. Finally, the Velcro hook 222 on the back surface of the second band body 220 is adhered with the Velcro fluff on the front surface of the second band body 220 which has been wound on the wrist.

[0100] When the wearable device is worn on the upper arm, the stimulator 100 is aligned with the inner skin of the upper arm (sensory nerve C fiber innervation area), and the first strap 210 and the second strap 220 are wound along the upper arm, the second strap 220 is pulled tight, and the Velcro hook surface 222 on the back of the second strap 220 is attracted to the Velcro loop surface, so that the first strap 210 and the second strap 220 form a loop structure that can be tied and fixed on the upper arm; because the upper arm is moderately thick, the Velcro hook surface 222 on the back of the second strap 220 may be attracted to the Velcro loop surface on the first strap 210 or the Velcro loop surface on the second strap 220 due to the different thicknesses of the upper arm.

[0101] Alternatively, the first strap 210 and the second strap 220 are provided with first magnets extending along their own length direction, and the back of the outer end of the second strap 220 is provided with a second magnet, wherein the first magnet and the second magnet on the second strap 220 are staggered in position, and the second magnet can be magnetically attracted to the first magnet. In this way, when the second magnet on the second strap 220 is attracted to the first magnet on the first strap 210 or the first magnet on the second strap 220, a loop structure of different sizes is formed, thereby adapting to the wrist, head, or upper arm.

[0102] In this way, when the wearable device is worn on the head, the stimulator 100 is aligned with the forehead nerve, and the first strap 210 and the second strap 220 are wound along the head, the second strap 220 is pulled tight, and the second magnet on the back of the second strap 220 is attracted to the first magnet, so that the first strap 210 and the second strap 220 form a loop structure that can be tied and fixed on the head; because the head is large, the second magnet on the back of the second strap 220 will be attracted to the first magnet on the first strap 210.

[0103] When the wearable device is worn on the wrist, the stimulator 100 is aligned with the wrist nerve, and the first strap 210 and the second strap 220 are wound along the wrist, the second strap 220 is pulled tight, and the second magnet on the back of the second strap 220 is attracted to the first magnet, so that the first strap 210 and the second strap 220 form a loop structure that can be tied and fixed on the head; because the wrist is thin, the second strap 220 may be wound around the wrist multiple times, and finally the second magnet on the back of the second strap 220 will be attracted to the first magnet on the second strap 220 that has been wound around the wrist.

[0104] When the wearable device is worn on the upper arm, the stimulator 100 is aligned with the skin on the inner side of the upper arm (sensory nerve C fiber innervation area), and the first strap 210 and the second strap 220 are wrapped along the upper arm, the second strap 220 is pulled tight, and the second magnet on the back of the second strap 220 is de-attracted from the first magnet, so that the first strap 210 and the second strap 220 form a loop structure that can be tied and fixed on the upper arm; due to the moderate thickness of the upper arm, the second magnet on the back of the second strap 220 may be attracted to the first magnet on the first strap 210 or the first magnet on the second strap 220 due to the different thicknesses of the upper arm.

[0105] It should be noted that in the embodiments of the present application, the back refers to the side facing the patient's skin when worn, and the front is the side facing outward when worn.

[0106] In the above embodiment, the length of the second strap 220 is longer than that of the first strap 210, the length of the first strap 210 is 8-12 cm, and the length of the second strap 220 is 50-60 cm, so that when worn on the wrist, only the second strap 220 needs to be wound multiple times on the wrist, and the first strap 210 does not need to be wound multiple times due to its insufficient length for the wrist dimension, which is beneficial for wearing.

[0107] In the above embodiment, the outer end of the first strap 210 is provided with a fixing ring 211, the outer end of the second strap 220 penetrates the fixing ring 211, and the outer end of the second strap 220 is provided with an anti-disengagement plug 221 to prevent the second strap 220 from sliding out of the fixing ring 211, thereby avoiding accidental complete separation of the first strap 210 and the second strap 220, reducing the risk of the wearable device falling off the patient; at the same time, the first strap 210 and the second strap 220 have action consistency through the restraining action of the anti-disengagement plug 221 and the fixing ring 211, pulling the second strap 220 along the fixing ring 211 can simultaneously pull the first strap 210 and the second strap 220, adjust the size of the loop structure, the operation is simple, and the second strap 220 presses the outer end of the first strap 210, avoiding the outer end of the first strap 210 turning outward from the first strap 210, making it more convenient to wear with one hand.

[0108] In the above embodiment, the shell is provided with a through hole 140 through which the second strap 220 penetrates along its own length direction, so that when the wearable device is worn on the wrist, the second strap 220 that needs to be wound multiple times on the wrist can pass through the through hole 140 to avoid covering the display screen 150 on the front of the stimulator 100. Of course, the second strap 220 and the through hole 140 are narrower than the stimulator 100, and there is still enough space inside the shell to set other components.

[0109] In addition, the wearable device in some embodiments of the present application can also adopt a combination of the adhesive band 230 and the flexible band, that is, the stimulator 100 can be equipped with the adhesive band 230 and the flexible band at the same time, at which time the adhesive band 230 and the flexible band are detachably connected with the stimulator 100. When the stimulator 100 is used on the head and the upper arm, the adhesive band 230 is used and the flexible band is detached; when the stimulator 100 is used on the wrist, the flexible band is used and the adhesive band 230 is detached. However, at this time, since the flexible band only acts on the wrist, the length does not need to be too long, and the length of the first band body 210 is 8-12 cm and the length of the second band body 220 is 10-15 cm.

[0110] The detachable connection mode of the adhesive band 230 and the stimulator 100 can refer to the foregoing structure. The detachable connection mode of the flexible band and the stimulator 100 can be realized in one of the following modes, of course, other modes can also be realized, which are not limited herein:

[0111] For example, the stimulator 100 is provided with a fixed ring on each side, the inner end of the first band body 210 and the inner end of the second band body 220 are respectively provided with a hook, and the hook is detachably connected with the fixed ring. Specifically, the hook has a hook body and a closed body rotatably connected with the hook body, the hook body hooks the fixed ring, and in the natural state, the closed body and the hook body form a closed ring, so that the first band body 210 and the second band body 220 are fixed on the fixed ring. Press the closed body, the closed body rotates and forms a gap with the hook body, so that the first band body 210 and the second band body 220 can be taken off from the fixed ring.

[0112] Alternatively, the inner end of the first band body 210 and the inner end of the second band body 220 are each provided with a fastening member, the fastening member includes a tenon and a mortise, the inner end of the first band body 210 and the inner end of the second band body 220 are inserted into the fixed ring and bent, and the bent part and the body of the first band body 210 / second band body 220 are respectively provided with a tenon and a mortise opposite to each other, and are fastened by the tenon and the mortise. The first band body 210 and the second band body 220 can be fixed on the fixed ring, under the action of external force, the tenon and the mortise are separated, so that the first band body 210 and the second band body 220 can be taken off from the fixed ring.

[0113] Alternatively, the stimulator 100 is provided with a pair of shaft holes on each side, and the inner ends of the first strap 210 and the second strap 220 are fixed with shafts that can be transversely inserted into the shaft holes on the same side of the stimulator 100, and the shafts are rotatably connected to the stimulator 100. Under the action of an external force, the shafts can be taken out of the shaft holes, so that the first strap 210 and the second strap 220 are separated from the stimulator 100, realizing the detachable connection of the flexible straps and the stimulator 100.

[0114] Of course, the fixing member can also be other structures that can fix the stimulator 100 on the wrist, which is not limited here. For example, in another embodiment of the present application, the flexible fixing member is or partially is an elastic ring, and the elastic ring can be sleeved on the wrist, head or upper arm by being expanded, and the ring body is shrunk under the elastic force of itself, so as to be tightly sleeved on the wrist, head or upper arm to form a fixing.
