[0077] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0078] At present, the electrodes used for electrical stimulation and physical therapy on the market are generally attached to the surface of human skin in the form of elastic bands, but the overall feeling of tightness is easy to bring discomfort to users, and are not suitable for long-term wear. In addition, the electrodes may not necessarily be well attached to the human skin.

[0079] Therefore, this embodiment provides a hand-worn device.

[0080] Refer to the attached Figure 1 The hand-worn device includes an electrode assembly 11 and a plurality of drive devices 22. The electrode assembly 11 is used to adhere to the surface of human skin and provide microcurrent to stimulate human nerves through microcurrent to achieve the effect of physical therapy. The drive device 22 is used to drive the electrode assembly 11 to adhere to the surface of human skin, so as to reduce the existing large area of ​​compression on the surface of human skin, improve the comfort of the user when using the hand-worn device, and can make the electrode assembly 11 adhere to the surface of human skin well to enhance the stimulation effect.

[0081] Specifically, the hand-worn device can be used on a bracelet, that is, the bracelet includes the hand-worn device described above. The wearable component 10 includes a strap 7 mounted on the wrist and a watch head connected to the strap 7 mounted on the wrist. When the user wears the bracelet on the wrist, the electrode assembly 11 can be aligned with the acupuncture points on the human wrist, so that when the driving device 22 is driven, the electrode assembly 11 can be close to the skin of the corresponding acupuncture points, such as the Neiguan acupoint, so that, in combination with microcurrent, it can achieve the effect of stopping vomiting, play an anti-motion sickness effect, and is convenient to carry. Among them, the electrode assembly 11 can be one electrode sheet or multiple electrode sheets, and the size of the electrode sheet can be customized by the manufacturer.

[0082] Specifically, the electrode assembly 11 is disposed on the driving device 22, that is, the electrode assembly 11 is indirectly disposed on the strap 7. When the driving device 22 is driven, the electrode assembly 11 can be directly driven to move to be close to the skin surface. In this embodiment, both the driving device 22 and the electrode assembly 11 can be disposed on the strap 7 or the watch head. In other embodiments, the driving device 22 and the electrode assembly 11 are disposed opposite to each other; that is, the driving device 22 is disposed on the strap 7, and the electrode assembly 11 can be disposed on the watch head; or, the electrode assembly 11 is disposed on the strap 7, and the driving device 22 can be disposed on the watch head; when the driving device 22 is driven, the strap 7 on the opposite side can be tightened by the reaction force, and the electrode assembly 11 can also be attached to the skin surface.

[0083] In order to realize the control of the electrode assembly 11 and the driving device 22, the wristband in this embodiment further includes a controller 00, which is electrically connected to the electrode assembly 11 and the driving device 22. The controller 00 is used to generate driving data for the driving device 22 and transmit the driving data to the driving device 22; the driving device 22 is used to make the electrode assembly 11 close to and close to the human skin according to the driving data; the electrode assembly 11 is used to apply electrical stimulation to the human skin based on the current signal output by the controller 00 when the human skin is in a close contact state.

[0084] In order to facilitate the understanding of the wristband provided by the embodiment of the utility model, the application scenario of the wristband is briefly introduced below. The wristband here can be mainly used in related scenarios when cars, ships or airplanes are in motion. This is mainly because in these related scenarios, any form of accelerated motion such as bumps, swings or rotations can stimulate the vestibular nerves of the human body and cause human discomfort, such as dizziness, vomiting, etc. It is precisely to alleviate the discomfort of the human body in the above application scenarios that an anti-motion sickness wristband that is easy to carry is provided here.

[0085] It should be noted that the wristband here can also be used in other scenarios. For example, for pregnant women in the morning sickness period, the wristband provided by the embodiment of the utility model can also effectively stop vomiting. In addition, it can also be applied to other related scenarios, such as stress relief, or hand tremor relief for ET tremor, without specific limitation. Considering the common situations of motion sickness, seasickness and other means of transportation, these scenarios are also used as examples in the following.

[0086] In order to avoid as much as possible the problem of poor effectiveness of electrical stimulation caused by the loose fit between the bracelet and human skin, the embodiment of the utility model can combine the cooperation between the controller 00 and the drive device 22 to make the bracelet produce the effect of squeezing the human skin, and then combine the cooperation between the controller 00 and the electrode assembly 11 to realize electrical stimulation under the squeezing state.

[0087] In some embodiments, the driving device 22 can be driven so that the electrode assembly 11 in the driving state can better fit the human skin and increase the contact pressure. At this time, the electrical stimulation performed will better relieve symptoms such as motion sickness and have a stronger anti-motion sickness effect.

[0088] The electrode assembly 11 in the embodiment of the utility model can be, for example, a single electrode sheet or a plurality of electrode sheets (for example, an electrode group formed by two electrode sheets). The driving device 22 here can be matched with one or more drivers, and no specific limitation is made here.

[0089] In some embodiments, the controller 00 can determine the driving data for the driver based on the contact pressure value between the electrode sheet and the human skin, and according to the driving data, the bracelet can produce the effect of squeezing the human skin.

[0090] The driving data here are mainly related control data that cause changes in the driving device 22. For example, when the driving device 22 includes a first airbag 221b, the control data here can be the inflation amount of the first airbag 221b, so as to control the contact strength between the first airbag 221b and the skin, thereby controlling the contact strength between the electrode assembly 11 and the human skin.

[0091] When it is determined that the change produced by the driving device 22 makes the contact pressure large enough, electrical stimulation can be applied to the electrode assembly 11 through the controller 00.

[0092] Specifically, the electrode assembly 11 may be disposed on the first airbag 221 b, or on the strap 7 at a side opposite to the first airbag 221 b.

[0093] Regardless of which of the above-mentioned matching methods is adopted, compared with the solution that simply relies on the strap to tighten, the bracelet provided by the utility model does not need to be worn tightly. Wearing the bracelet loosely can still ensure that the electrodes are close to the skin and maintain a stable contact resistance. It can also ensure comfort of use while ensuring the effectiveness of electrical stimulation.

[0094] In addition, under the squeezed state, the electrode assembly 11 is pushed into the sunken skin, making the electrode assembly 11 physically closer to the median nerve deep in the wrist, and the electric field propagates more efficiently in the body. Electrical stimulation of the same power is more likely to produce a better stimulation effect, further improving the effectiveness of the stimulation.

[0095] Considering the key role of the driving device 22 for the wristband provided by the embodiment of the utility model, the driving device 22 will be introduced in detail below.

[0096] The driving device 22 here can be implemented in a variety of structures. The embodiment of the utility model mainly provides the following nine implementation methods:

[0097] The first method: the driving device 22 includes an air pump 221a and a first air bag 221b. Figure 2(a) to Figure 2(d) Provide an example.

[0098] The air pump 221a is electrically connected to the controller 00. The air pump 221a inflates the first airbag 221b according to the driving data, and the first airbag 221b is deformed to drive the electrode assembly 11 to approach and squeeze the human skin. Alternatively, the first airbag 221b is deformed to directly squeeze the human skin, and the reaction force is used to make the electrode assembly 11 on the opposite side close to the human skin.

[0099] In order to determine a more accurate deformation of the first airbag 221b, a pressure sensor can be used here to obtain the contact pressure value between the electrode assembly 11 and the surface of human skin in real time or non-real time (such as timing). The larger the pressure value, to a certain extent, it indicates that the electrode assembly 11 fits tightly to the human skin, and the required deformation amount is relatively small. Conversely, the smaller the pressure value, to a certain extent, it indicates that the electrode assembly 11 fits loosely to the human skin, and the required deformation amount is relatively large.

[0100] like Figure 2(a) to Figure 2(c) As shown, the first airbag 221b and the electrode assembly 11 are both arranged in the controller 00. In addition, the first airbag 221b and the electrode assembly 11 can also be arranged in combination with different application requirements. For example, the first airbag 221b is arranged on the strap 7 and at a position different from the controller 00, and the electrode assembly 11 is arranged on the first airbag 221b; for example, the first airbag 221b is arranged in the controller 00, and the electrode assembly 11 is arranged at a position of the strap 7 different from the controller 00; for example, the first airbag 221b is arranged on the strap 7 but not on the controller 00, and the electrode assembly 11 is arranged on the controller 00; for example, the first airbag 221b is arranged on the strap 7 and the controller 00, and the electrode assembly 11 is arranged on the strap 7, the controller 00 or the first airbag 221b.

[0101] like Figure 3(a) to Figure 3(e) As shown in the bracelet structure diagram, the number and position of the first airbags 221b and the electrode assembly 11 in the bracelet provided by the embodiment of the utility model can be set as needed, and there is no specific limitation on this.

[0102] As shown in FIG. 2( d ), it is an expanded structural diagram of the first type of driving device 22 of the present utility model embodiment. The structural diagram is only an example form. In actual application, it can also be in other forms, which is not specifically limited here.

[0103] The second method: the driving device 22 includes an air pump 222a and a cylinder 222b connected to the air pump 222a through an air pipe. When the air pump 222a blows air into the cylinder 222b, the cylinder 222b drives the electrode assembly 11 to adhere to the skin surface.

[0104] The air pump 222a is electrically connected to the controller 00. Specifically, the air pump 222a determines the movement amount of the piston inside the cylinder 222b according to the driving data. The cylinder 222b drives the internal piston to move according to the movement amount to directly push the electrode assembly 11 to move toward the inside of the bracelet to produce the effect of squeezing the human skin; or, the cylinder 222b drives the internal piston to move according to the movement amount to directly or indirectly squeeze the human skin, so that the electrode assembly 11 moves toward the inside of the bracelet to produce the effect of squeezing the human skin.

[0105] The cylinder 222b here can be a micro cylinder. When the air pump 222a blows air into the micro cylinder, the piston of the micro cylinder will move and drive the electrode assembly 11 to move toward the inside of the bracelet to produce the effect of squeezing human skin.

[0106] like Figure 4 As shown, it is an expanded structural diagram of the above-mentioned second mode driving device 22 of an embodiment of the utility model. This structural diagram is only an example form. In actual application, it can also be other forms, which are not specifically limited here.

[0107] The third method: the driving device 22 includes a motor 223a, a screw 223b connected to the output shaft of the motor 223a, a screw nut 223c used in conjunction with the screw 223b, and a slider 223d arranged on the screw nut 223c. The slider 223d drives the electrode assembly 11 to be close to the skin surface when the screw 223b rotates.

[0108] The motor 223a is electrically connected to the controller 00, wherein the motor 223a determines the rotation amount of the screw rod 223b according to the driving data; the screw rod 223b drives the screw nut 223c to move according to the rotation amount, so as to drive the electrode assembly 11 to move toward the inside of the bracelet through the slider 223d to produce the effect of squeezing the human skin.

[0109] like Figure 5 As shown, the motor 223a drives the screw 223b to rotate, and the screw nut 223c on the screw 223b moves and drives the electrode assembly 11 to move through the slider 223d to produce an extrusion effect. This structural diagram is only an example form. In actual applications, it can also be other forms, which are not specifically limited here.

[0110] Fourth mode: the driving device 22 includes a motor 224a, a gear 224b connected to the motor 224a, and a rack 224c meshing with the gear 224b. When the gear 224b rotates, the rack 224c drives the electrode assembly 11 to be close to the skin surface. The motor 224a is electrically connected to the controller 00.

[0111] Among them, the motor 224a determines the rotation amount of the gear 224b according to the driving data; the gear 224b drives the rack 224c to move according to the rotation amount, so as to drive the electrode assembly 11 to move toward the inside of the bracelet to produce the effect of squeezing the human skin.

[0112] like Figure 6 As shown, the motor 224a drives the gear 224b to rotate, the gear 224b drives the rack 224c to move, and the rack 224c further drives the electrode assembly 11 to move to produce a squeezing effect. This structural diagram is only an example form, and in actual applications, it can also be other forms, which are not specifically limited here.

[0113] The fifth mode: the driving device 22 is an electric push rod, which drives the electrode assembly 11 to be close to the skin surface when working.

[0114] The electric push rod is electrically connected to the controller 00; wherein the electric push rod determines the movement amount of the internal piston according to the driving data to drive the electrode assembly 11 to move toward the inside of the bracelet to produce the effect of squeezing the human skin. In addition, the electric push rod can also directly squeeze the human skin according to the movement amount to make the electrode assembly 11 move toward the inside of the bracelet to produce the effect of squeezing the human skin. Specifically, the electric push rod can be a micro electric push rod.

[0115] In practical applications, the embodiments of the utility model may also adopt a worm gear reduction electric push rod mode, a motor gear reduction electric push rod mode, or other electric push rod modes, without specific limitations herein.

[0116] The sixth mode: the driving device 22 includes a coil 226a and a magnet. When the coil 226a is energized, the magnet moves to drive the electrode assembly 11 to be close to the skin surface. The coil 226a is electrically connected to the controller 00.

[0117] When the coil 226a is energized and generates magnetism, the electrode assembly 11 moves toward the inside of the bracelet based on the repulsive movement between the coil 226a and the magnet to produce the effect of squeezing the human skin.

[0118] like Figure 7 As shown, the coil 226a generates magnetism when it is energized, so that magnets with the same magnetism repel each other and move to produce a squeezing effect on the electrode assembly 11. This structural diagram is only an example form, and in actual applications, it can also be in other forms, which are not specifically limited here.

[0119] In other embodiments, the electrode assembly 11 is a magnet having a polarity that repels the coil 226 a .

[0120] The seventh mode: the driving device 22 comprises a motor 227a and a crank 227b electrically connected to the motor 227a. When the motor 227a is driven, the crank 227b drives the electrode assembly 11 to be close to the skin surface. The motor 227a is electrically connected to the controller 00.

[0121] Among them, the motor 227a determines the rotation amount of the crank 227b according to the driving data; the crank 227b drives the electrode assembly 11 to move toward the inside of the bracelet according to the rotation amount to produce the effect of squeezing the human skin.

[0122] As shown in FIG. 8( a ), the motor 227 a drives the crank 227 b to rotate, and the crank 227 b drives the electrode assembly 11 to move to produce a squeezing effect.

[0123] As shown in FIG8( b ), it is an expanded structural diagram of the seventh driving device 22 of the utility model embodiment. The structural diagram is only an example form. In actual application, it can also be in other forms, which is not specifically limited here.

[0124] The eighth mode: the driving device 22 includes a motor 228a, a gear 228b connected to the motor 228a and having a screw 228c, a screw nut 228d movably disposed on the screw 228c, and a slider 228e disposed on the screw nut 228d. The gear 228b drives the screw 228c to rotate when the motor 228a is driven, and the screw nut 228d drives the slider 228e to move when the screw 228c rotates to drive the electrode assembly 11 to be close to the skin surface. The motor 228a is electrically connected to the controller 00.

[0125] As shown in FIG9(a) and FIG9(b), the motor 228a determines the rotation amount of the gear 228b according to the driving data; the screw nut 228d is driven by the screw 228c to produce an up and down displacement, so as to drive the electrode assembly 11 to move toward the inside of the bracelet through the slider 228e to produce the effect of squeezing the human skin. Specifically, there are multiple gears 228b, and the deceleration effect is achieved by using the effect of multiple gear transmissions. This structural diagram is only an example form. In actual applications, it can also be other forms, which are not specifically limited here.

[0126] The ninth mode: the driving device 22 includes a motor 229, a worm 229b connected to the motor 229, and a screw 229c connected to the worm 229b. When the screw 229c rotates, the nut on the worm 229b drives the electrode assembly 11 to be close to the skin surface, and the motor 229 is electrically connected to the controller 00.

[0127] like Fig.10 As shown, the motor 229 determines the rotation amount of the worm 229b according to the driving data; the worm 229b drives the turbine to rotate according to the rotation amount, so that when the turbine rotates coaxially with the screw 229c, the screw 229c drives the electrode assembly 11 to move through the nut on itself when the worm 229b rotates to achieve the effect of squeezing the skin surface. This structural diagram is only an example form, and in actual applications, it can also be other forms, which are not specifically limited here.

[0128] Regardless of the above implementation method, the wristband provided by the embodiment of the utility model can be combined with the air pressure sensor 20 to achieve better drive control and electrical stimulation control.

[0129] In actual applications, the air pressure value generated by the driving device 22 can be detected by the air pressure sensor 20 and the air pressure value can be transmitted to the controller 00. In this way, the controller 00 can determine the driving data for the driving device 22 and the electrical stimulation signal for electrical stimulation of the electrode assembly 11 based on the air pressure value and the current contact pressure value of the electrode assembly 11.

[0130] Taking the first airbag 221b and the air pump 221a shown in Figures 2(b) and 2(c) as the driving device 22 as an example, the air pressure sensor 20 can be set in the first airbag 221b. In this way, the air pressure sensor 20 can detect the air pressure value inside the first airbag 221b in real time. The controller 00 can then determine the driving data suitable for the air pump 221a based on this air pressure value and the contact pressure value measured by the pressure sensor 30.

[0131] In the embodiment of the utility model, the controller 00 reads the measured value of the air pressure sensor 20 in the first airbag 221b, so as to realize the effective control of the air pressure in the first airbag 221b through the air pump 221a. Here, on the one hand, a precise instantaneous air pressure fluctuation curve can be used to simulate the physical acupressure function of traditional Chinese medicine, and the excitement of the median nerve can be enhanced by physical acupressure, which significantly improves the effectiveness of the stimulation. On the other hand, the air pressure change in the first airbag 221b can be quickly switched, and the hardness of the first airbag 221b and the depth of the top concave skin can be changed to simulate the function of physical repeated pressing and vibration rubbing. This function cooperates with electrical stimulation to effectively activate the median nerve deep in the wrist, and achieves the superposition effect of auxiliary massage, acupuncture or electromoxibustion during traditional Chinese medicine diagnosis and treatment, and the practicality is further improved.

[0132] It should be noted that the air pump 221a here can also adjust the gas pressure in the first airbag 221b according to a curve according to different electrical stimulation modes. For example, continuous and stable pressure control of the first airbag 221b can be achieved through the air pump 221a.

[0133] Here, electrical stimulation is achieved by combining the mutual cooperation between the controller 00, the air pump 221a, the first airbag 221b, the air pressure sensor 20, and the pressure sensor 30. In the process of the air pump 221a driving the first airbag 221b to adjust, the pressure sensor 30 can record the skin pressure at the electrode assembly 11 caused by the strap 7 (herein referred to as the strap 7 pressure), and the controller 00 calculates the optimal sine curve for applying the pressure to the first airbag 221b based on the strap 7 pressure, such as Fig.11 As shown, in the case of a large air pressure change indicated by the peak of the curve, applying electrical stimulation to the electrode assembly 11 can further enhance the effectiveness of the electrical stimulation. This is mainly because a large air pressure change will enable the bracelet to better fit the human skin. In this way, under the same stimulation energy, a more concentrated electrical stimulation can be performed, and the stimulation effect is better at this time.

[0134] Specifically, if Fig.11 The curve 111 shown in the figure represents the pressure change curve in the first airbag 221b; 112 represents the amplitude between the peak and the trough of the pressure curve of the first airbag 221b, 113 represents the duration of one cycle of inflation and deflation of the first airbag 221b, 114 represents the time period of electrical stimulation when the air pressure in the first airbag 221b reaches half of the amplitude, 115 represents the waveform curve of electrical stimulation, and 116 represents the maximum amplitude difference of the waveform curve of electrical stimulation.

[0135] In addition, the dashed line profile in the curve 115 represents the envelope range of the oscillation curve 115 that changes with time. Here, it is described that as the air pressure increases to the top, the amplitude difference of the electrical stimulation also increases to the top, and as the air pressure decreases, the amplitude of the electrical stimulation also decreases.

[0136] like Fig.11 It can be seen that the detailed waveform of the electrical stimulation here takes a bidirectional square wave as an example. For example, the bidirectional square wave is released through the electrode sheet fixed on the first airbag 221b. This bidirectional square wave can ensure that the integral area under the curve is 0. Since the areas covered by the positive and negative square waves are offset by each other, there is no charge accumulation, thereby further improving the effect of electrical stimulation therapy. For example, when acting on the Neiguan acupoint, it can further improve the anti-dizziness and anti-vomiting treatment effects. At the same time, the quasi-sinusoidal curve adjustment method used here can also allow users to pay attention to the breathing frequency, and by diverting attention, it can also alleviate the discomfort caused by motion sickness to a certain extent.

[0137] also, Fig.11 Here, m and n are used to indicate the number of repetitions of the pulse signal and the number of repetitions of the pressure signal, respectively. This is just a specific example, and the values ​​of m and n are not specifically limited.

[0138] In practical applications, in order to further enhance the user experience of different users, the wristband provided in the embodiment of the utility model can prompt the user to adjust when the contact force is too large or too small, that is, the strap 7 can be an adjustable tightness belt. This is mainly because too little pressure can easily lead to insufficient contact between the electrode and the skin, resulting in increased electrode contact resistance, reduced effectiveness of electrical stimulation, and increased skin heating, while too much pressure can easily cause discomfort to the patient. In order to solve the above problems, the controller 00 here can analyze and adjust the tightness of the wristband according to the pressure data recorded by the pressure sensor 30.

[0139] Here, when the controller 00 determines that the contact pressure value between the electrode assembly 11 and the human skin surface is less than the preset pressure value, a reminder signal for reminding the user to tighten the bracelet can be generated, and the user is prompted to tighten the bracelet through the display screen 33, such as Figure 1 shown.

[0140] In actual use of the bracelet, the bracelet may also include at least one protrusion for pressing acupuncture points, specifically, the protrusion is a convex point or a metal sheet, etc. Among them, the protrusion is arranged on the first airbag 221b, and massage is achieved when the first airbag 221b is inflated. Of course, in other embodiments, the protrusion may also be arranged on the second airbag 4, the watch head or the watch strap 7, and the position of the protrusion is not limited here.

[0141] In the actual use of the bracelet, the bracelet also includes a second airbag 4 for pressing acupoints, that is, after the first airbag 221b drives the electrode assembly 11 to move to achieve electrical stimulation, the user can also press the electrically stimulated acupoints through the second airbag 4 to further stimulate the acupoints to achieve a better effect of stimulating the acupoints.

[0142] Among them, the second airbag 4 may not be connected to the air pump 221a, and the user can stimulate the acupoints by pressing the second airbag 4 as needed. Of course, the second airbag 4 can also be connected to the air pump 221a to be inflated under the action of the air pump 221a for use by the user. In addition, the second airbag 4 can have the same working mode as the first airbag 221b, that is, it can be inflated and deflated following the first airbag 221b to achieve synchronous action with the first airbag 221b; it can also be inflated and deflated separately with the first airbag 221b, providing users with more usage modes and improving the usage experience.

[0143] In actual use, the number of first airbags 221b can be multiple, the number of electrode assemblies 11 is equal to the number of first airbags 221b, one electrode assembly 11 is configured correspondingly to one first airbag 221b, and the size of the first airbag 221b can be larger than the size of the electrode assembly 11, such as the first airbag 221b can extend along the direction of the strap 7, that is, it can occupy the inner side of the entire strap 7. Of course, in other embodiments, the number of first airbags 221b can also be one, in which case the length and width of the electrode assembly 11 can be relatively increased to effectively press the acupuncture points on the wrist. Specifically, the number of first airbags 221b can be two, and they are respectively located on both sides of the second airbag 4.

[0144] In one embodiment, the first airbag 221b and the second airbag 4 are both inflatable and deflable airbags, that is, the first airbag 221b and the second airbag 4 can press, stimulate and massage the acupuncture points on the wrist by inflating and deflating.

[0145] Specifically, in one embodiment, both the first airbag 221b and the second airbag 4 are provided with a charging and discharging interface 61. In other embodiments, the first airbag 221b and the second airbag 4 may be an integrated structure, and the first airbag 221b and the second airbag 4 are connected, so that the first airbag 221b and / or the second airbag 4 are provided with a charging and discharging interface 61, and the charging and discharging interface 61 is connected to the air pump 221a to realize the charging and discharging of the first airbag 221b and the second airbag 4.

[0146] The display screen 33 in the embodiment of the utility model can also realize targeted display of various data such as the intensity of electrical stimulation, the force of the electrode assembly 11, countdown protection information to prevent long-term use by the user, breathing patterns, user health data, etc. based on the application needs of different users.

[0147] In addition, the display screen 33 of the embodiment of the utility model can also be a touch display screen 2, which can respond to the touch control instructions of the wearer for the target task and display the control results of the target task. What is displayed here can be, for example, information such as the intensity of electric stimulation massage, the pressure intensity, etc., and can also be related information of other controllable or adjustable gears. The utility model does not make specific restrictions on this.

[0148] It should be noted that the embodiment of the utility model can be provided with a simple function display screen 33 and a touch display screen 2 at the same time, and can also be provided with a display screen 33 with a touch function. In this way, when a touch operation is required, the touch function can be realized by unlocking. A small touch partition can also be provided on the display screen 33 to support the touch function. There is no specific restriction on this.

[0149] Considering that in the actual process of electrical stimulation, excessively high or low temperature may cause discomfort to the user, it is necessary to combine the temperature sensor 40 to measure the temperature to set a safe temperature wall for electrical stimulation. The temperature sensor 40 in the wristband provided by the embodiment of the utility model is electrically connected to the controller 00, and can detect the temperature value between the electrode assembly 11 and the surface of the human skin so that the controller 00 can determine the electrical stimulation strategy for the electrode assembly 11 according to the temperature value, and / or determine the temperature adjustment strategy for the drive device 22.

[0150] Among them, the relevant temperature sensor 40 can be set near the electrode assembly 11 to determine the heating condition of the electrode. Here, if the temperature measured by the temperature sensor 40 reaches the discomfort line (for example, 39 degrees), the controller 00 can modify the stimulation mode to the comfort mode, set the stimulation intensity to the middle gear, and issue a sound and vibration prompt based on the reminder component, and can also prompt the change of the stimulation strategy through the display screen 33 at the same time. If the temperature reaches the warning line (for example, 41 degrees), the controller 00 can modify the stimulation mode to the comfort mode, set the stimulation intensity to the lowest, and issue a sound and vibration prompt based on the reminder component, and can also prompt the user of the current temperature and the change of the stimulation strategy through the display screen 33.

[0151] It can be known that the controller 00 in the embodiment of the utility model can change the electrical stimulation intensity for the electrode assembly 11, for example, lower the stimulation intensity, when determining that the temperature value exceeds the preset temperature threshold. At the same time, the user can be reminded in time through the reminder component.

[0152] In practical applications, such as Figure 1 As shown, the wristband provided by the embodiment of the utility model can also be provided with a heating component 44 (such as a heater), and the heater is electrically connected to the controller 00. In this way, when the controller 00 determines that the driving device 22 needs to be heated, the heating component 44 is controlled to heat the driving device 22.

[0153] In order to explain the specific heating principle, the following example is given in combination with the matching structure of the air pump 221a and the first air bag 221b.

[0154] Regarding the heating of the first airbag 221b, it is mainly used to simulate the effect of hot moxibustion, further exciting the median nerve by increasing the temperature to enhance the stimulation effect. In addition, the temperature change induces sweating at the skin contact point where the airbag top is concave. Sweat is conductive and can make the dry electrode surface wet with saline solution, reducing the contact resistance, thereby significantly improving the effectiveness of the stimulation.

[0155] In actual applications, the controller 00 in the embodiment of the utility model can obtain the temperature change in the first airbag 221b by reading the temperature value of the temperature sensor 40, and control the heater based on the temperature change to make the temperature in the first airbag 221b stable or fluctuate according to a curve, thereby achieving stable, continuous and effective electrical stimulation.

[0156] In actual applications, as the bracelet is worn for a longer period of time or under the influence of a complex wearing environment, the user may sense that the bracelet is overheated. In this case, the bracelet can be cooled by the cooling component 55. Figure 1 shown.

[0157] It should be noted that the embodiments of the utility model can achieve the technical purpose of applying an electrical stimulation signal to the electrode based on the determination result of the preset electrical stimulation condition. The preset electrical stimulation condition here can be considered based on a single factor, for example, electrical stimulation can be applied only when it is determined that the contact pressure is large enough, or it can be determined based on multiple factors, for example, electrical stimulation is applied only when it is determined that the contact pressure is large enough and the sensed temperature is not very high. Specifically, it can also be combined with user health data, air pressure change data, etc. for comprehensive judgment, and no specific restrictions are made here.

[0158] like Figure 1 As shown, the wristband provided in the embodiment of the utility model can, on the one hand, realize switch control of the wristband based on the switch component 66, or realize switch setting for electrical stimulation mode, intensity, etc.; on the other hand, it can realize relative gear adjustment based on the rotary encoder 77, which is described in detail in the following two aspects.

[0159] First aspect: when controlling based on the switch component 66, the switch component 66 here can obtain the switch signal triggered by the user, and determine the switch state of the bracelet or the electrical stimulation mode of the electrode component 11 through analysis and processing by the controller 00.

[0160] In actual applications, the switch component 66 can control the power on / off state of the bracelet or control the switching of the electrical stimulation mode of the electrode component 11 through the response of the first switch, and can also control the electrical stimulation intensity of the electrode component 11 through the response of the second switch.

[0161] It should be noted that the above switch setting is only a specific example. In specific applications, for example, a switch can be set separately to realize the electrical stimulation mode, or the electrical stimulation mode and the electrical stimulation intensity can be integrated into one switch operation. No specific limitation is made here.

[0162] Whether it is the first switch, the second switch or other switches, they can be set on the side of the header. For example, each switch can be embedded through multiple openings set on the side of the header. The appearance shape of the relevant switches can be, for example, round, oval, square, etc., and there is no specific limitation here. The relevant switches can be physical button switches or virtual touch switches, etc., and there is no specific limitation here.

[0163] The second aspect: when controlling based on the rotary encoder 77, the rotary encoder 77 responds to the rotational adjustment operation, and determines the degree of electrical stimulation for the electrode assembly 11 based on the change in the amount indicated by the rotational adjustment operation so that the controller 00 applies electrical stimulation matching the degree of electrical stimulation to the electrode assembly 11; or, determines the force with which the electrode assembly 11 is ejected so that the controller 00 applies a matching pressing force to the electrode assembly 11; or, determines the time or countdown for the electrode assembly 11 to be ejected so that the controller 00 applies a matching pressing time to the electrode assembly 11.

[0164] It can be seen that the corresponding rotation control operation is implemented based on the rotary encoder 77, which will further improve the practicality in different application scenarios.

[0165] In order to further improve the practicality of the wristband provided by the embodiment of the utility model, a breathing adjustment component 88 may also be provided here, such as Figure 1 As shown, the breathing adjustment component 88 is electrically connected to the controller 00; in this way, when the breathing adjustment component 88 applies electrical stimulation to the human skin, it can remind the user who wears it to adjust his breathing according to the preset breathing pattern, thereby alleviating the discomfort such as when the user is in a state of motion sickness.

[0166] The wristband here can also be provided with a health data collection component 99, such as Figure 1 As shown, the health data collection component 99 is electrically connected to the controller 00; the health data collection component can collect the health data of the wearer in real time or periodically.

[0167] The health data includes at least one or more of the following data: body temperature, blood pressure, blood oxygen, and heart rate.

[0168] Based on the collection of the above health data, the controller 00 can also provide health analysis and health reports based on the health data. And the embodiment of the utility model can provide timely support when the user is in slight discomfort. In addition, when the user is in obvious discomfort, emergency rescue measures (such as reporting danger signals to the emergency contact terminal bound to the bracelet) can be taken to help the user overcome difficulties.

[0169] In the above-mentioned embodiments of the utility model, the basic components of the wristband are not specifically marked. In order to facilitate further understanding of the embodiments of the utility model, the following is combined with Figures 12(a) to 12(d) The structural schematic diagram shown illustrates the specific structure of the first airbag 221b driving electrode assembly 11.

[0170] The wristband in the embodiment of the utility model further includes a housing 1, which is arranged on the strap 7. The controller 00 is a circuit board and is arranged in the housing 1. The touch display screen 2 is arranged on the housing 1, and the first airbag 221b, the second airbag 4, the air pump 221a, the switch assembly 66, the air pump, the airbag, the temperature sensor 40, the pressure sensor 30, etc. can all be arranged in the housing 1. The strap 7 can be a belt body that can be adjusted in tightness or elasticity through a mechanical structure, for example, it can be a nylon braided belt body with slight elasticity and adjustable tightness, which has excellent characteristics such as skin-friendly, hypoallergenic, and breathable.

[0171] In practical applications, the driving device 22 is preferably arranged on the housing 1 to facilitate the fixing and installation of the driving device 22. Of course, the driving device 22 may also be arranged on the strap 7 instead of on the controller 00.

[0172] In order to facilitate information display, a touch display screen 2 is arranged on the top surface of the housing 1. The touch display screen 2 can timely remind the user to tighten the bracelet. In addition, other related prompts such as low battery can also be given.

[0173] In order to facilitate more direct electrical stimulation, a first opening 5 can be provided on the bottom of the shell 1, so that when the first airbag 221b and the second airbag 4 are inflated and deformed, they protrude from the first opening 5 and the outside of the shell 1 to drive the electrode assembly 11 to squeeze the surface of human skin.

[0174] In actual application, the first airbag 221b is bonded and integrated with the pressure sensor 30, the electrode assembly 11 and the temperature sensor 40. When the first airbag 221b is inflated, the pressure sensor 30, the electrode assembly 11 and the temperature sensor 40 are pushed out from the first opening 5.

[0175] Considering that polycarbonate (PC) has excellent properties such as high strength and elastic coefficient, high impact strength, and a wide operating temperature range, the housing 1 here can be made of PC material, with a second opening (not shown) for the touch display screen 2, switch assembly 66, etc. to pass through the housing 1, and the second opening and the connection with other components are waterproofly encapsulated by encapsulating glue, such as polyurethane glue. The housing 1 can also be made of skin-friendly silicone or titanium alloy material, and connected to other components by waterproof glue.

[0176] In actual use, the hand wearable device can also be used on the base of the thumb, that is, the wearable device 10 is a fulcrum 102 and three belts 101 connected to the fulcrum 102. Among them, optimally, the driving device 22 is arranged on the belt 101, and the electrode assembly 11 is arranged on the driving device 22, so that when the driving device 22 is driven, the electrode assembly 11 is directly driven to press the surface of the human skin. In other embodiments, the electrode assembly 11 and the driving device 22 are arranged at similar relative positions, which can also achieve the effect of driving the electrode assembly 11 to press the surface of the human skin when the driving device 22 is driven.

[0177] In an embodiment of a wearable device, a controller 00 as in the wristband embodiment may also be included, the controller 00 may be fixed on the fulcrum 102 through the housing 1, the driving device 22 is disposed on the controller 00, and the function of the controller 00 is consistent with the above description, etc. Alternatively, the controller 00 is the fulcrum 102.

[0178] Here, when the user wears the wearable device at the base of the thumb, the electrode assembly 11 is pressed against the base of the thumb (i.e., the Hegu point) through the driving device 22. The Hegu point is a position where the vital energy in the body needs to pass through and stay. By stimulating or massaging the base of the thumb, it can calm pain, relax muscles and tendons, and enhance body resistance, which has a good physical therapy effect on the human body. And by pressing the electrode assembly 11 against the human skin through the driving device 22, the problem that the electrode sheet in the existing structure for electrically stimulating the base of the thumb cannot be well pressed against the human skin and affects the use can be solved.

[0179] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0180] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "and / or" in the full text includes three solutions. Taking A and / or B as an example, it includes technical solution A, technical solution B, and technical solution that satisfies both A and B; in addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0181] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
