Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wrist-worn nerve stimulator suitable for both left and right hands and its method of use. Background Technology

[0002] A wrist-worn neurostimulator is a small, wearable electrical stimulation device worn on the wrist. Electrodes attached tightly to the wrist stimulate the median, radial, and / or ulnar nerves distributed in the hand according to a specific pattern. Typically, a tremor test is first used to assess the tremor intensity in the user's left and right hands; the hand with the stronger tremor is chosen. If both hands have similar tremor intensity, the more dominant hand is selected. The band electrodes generally do not have a long lifespan and need to be replaced within their expiration date to ensure optimal treatment results.

[0003] To achieve the best therapeutic effect, it is necessary to select the appropriate stimulation intensity and corresponding specifications of electrode pads and bands for electrotherapy on the left or right hand according to the doctor's guidance. Existing wrist-worn neurostimulators lack simple and intuitive wearing instructions, which can easily lead to user misoperation and delay treatment. When the band electrodes are about to expire and need to be replaced, the device does not provide advance notice, causing users to fail to replace them in time and continue to use expired ones, which will seriously affect the treatment effect. Incompatible electrode pads and bands cannot be identified by ID, which will affect the treatment effect and even pose serious safety hazards. Existing devices cannot be used on both the left and right hands, resulting in poor compatibility. Summary of the Invention

[0004] The purpose of this invention is to provide a wrist-worn neurostimulator suitable for both left and right hands and its method of use, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wrist-worn nerve stimulator suitable for both left and right hands, comprising,

[0006] A fixed host is provided with grooves and adapters on both sides of its bottom. The fixed host is equipped with a controller, which includes at least a main control MCU, a storage unit and a stimulation unit.

[0007] The electrode strip includes a base and an electrode assembly. Adapter seats are provided on both sides of the top surface of the base, and the shapes of the two adapter seats are adapted to the shapes of the groove and the adapter interface.

[0008] Preferably, the adapter has multiple PIN points, and the controller is electrically connected to all of the multiple PIN points. The controller also includes an intelligent identification unit.

[0009] Preferably, the base contains a storage IC, the two adapters are electrically connected to the storage IC, the storage IC has an independent identification ID, the electrode assembly has multiple electrode plates, the two adapters are electrically connected to the multiple electrode plates, and the adapters have multiple PIN pins that are compatible with the PIN points.

[0010] Preferably, the bottom of the fixed host is provided with a plurality of first magnetic blocks, which are respectively located on the front and rear sides of the groove and the front and rear sides of the adapter. The base is provided with a plurality of second magnetic blocks that are adapted to the first magnetic blocks.

[0011] Preferably, the adapter interface is provided with multiple PIN points, the adapter base is provided with multiple PIN pins, and the fixed host and the electrode sheet bundle are electrically connected through the contact of the PIN points and the PIN pins.

[0012] Preferably, the main control MCU is model NRF52840 and the storage IC is model DS2431Q.

[0013] Preferably, the intelligent identification unit is used to identify the identification ID stored in the IC and monitor the number of times or duration of use of the electrode sheet bundle.

[0014] Preferably, the fixed host is also equipped with a display screen, control buttons and a charging interface.

[0015] Preferably, it also includes an adjustment belt, the two ends of which are movably connected to both sides of the fixed host.

[0016] A method for using a wrist-worn nerve stimulator suitable for both hands, characterized by comprising:

[0017] S1: One side of the adapter is embedded in the adapter interface, and the other side of the adapter is embedded in the groove. The first magnetic block and the second magnetic block are attracted and connected, and the main unit and the electrode sheet bundle are fixed to complete the quick installation. The main unit and the electrode sheet bundle are connected by the mutual contact of the PIN point and the PIN pin, and the main unit and the electrode sheet bundle are electrically connected.

[0018] S2: The intelligent identification unit can identify the connection pins of the controller and the storage IC, and determine the connection orientation of the electrode strip according to the preset parameters of the fixed host. If the connection orientation is correct, the fixed host and the electrode strip can be used normally. If the connection orientation is incorrect, the fixed host and the electrode strip cannot be used, and the fixed host will continuously issue an alarm signal until the orientation is reversed before it can be used normally.

[0019] S3: The intelligent identification unit simultaneously detects the independent identification ID in the storage IC. It compares the parameters in the storage unit with the identification ID to determine whether it is a compatible electrode strip. If it is a compatible electrode strip, the host and the electrode strip can be used normally. If it is an incompatible electrode strip, the host and the electrode strip cannot be used, and the host will continuously issue an alarm signal until a compatible electrode strip is replaced. The storage IC can be used to record the number of times or the duration of use of the electrode strip. If the number of times or the duration of use exceeds the preset number of times or the duration of use, it cannot be used until a qualified electrode strip is replaced.

[0020] S4: The user's wrist passes through the annular opening between the main unit and the adjustment strap, and the adjustment strap is used to adjust the wearing position so that the electrode pads on the electrode pad strap fully fit the user's skin;

[0021] S5: Controlled by the human-machine interface on the fixed host, the fixed host outputs current to the electrode pads, and the electrode pads generate current to perform electrotherapy on the user.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention, by setting up a storage IC, allows the electrode pad bundle to record and save usage data in real time when used with the fixed host. When the electrode pad bundle is about to expire, it can remind the user to replace it in time. If the user continues to use it after the expiration date, the fixed host will lock the device. After replacing the electrode pad bundle with a new one, the device can continue to be used normally. Furthermore, the identification ID in the storage IC can be monitored by the intelligent identification unit to ensure that the identification ID is compatible with the electrode pad bundle, thus guaranteeing the effectiveness and safety of the user's use.

[0024] 2. This invention, through the setting of a controller, allows the intelligent identification unit to determine the connection orientation of the electrode pads when connected to the fixed host based on the connection pins of the controller and the storage IC. Specifically, it determines whether the adapter is connected to the left or right adapter. The connection pin data is stored in the storage unit. When the connection pins of the storage IC match the pin data, the fixed host and electrode pads function normally. When the connection pins of the storage IC do not match the pin data, the fixed host and electrode pads cannot be used, and a fault alarm is issued through the fixed host. Wearing instructions are displayed on the human-machine interface screen, guiding the user to install correctly, ensuring the correctness and safety of user operation. Furthermore, the storage unit can store stimulation parameters, and the stimulation unit outputs appropriate current to the electrode pads according to these parameters, ensuring the user achieves the best therapeutic effect.

[0025] 3. This invention utilizes a groove and adapter on the bottom of the fixed main unit, along with two adapters on the base. These two adapters can be rotated and embedded into the adapter, electrically connecting the electrode pads to the fixed main unit. The adapters embedded in the groove provide insulation and do not affect the normal use of the wrist-worn nerve stimulator. When worn, the control buttons on the fixed main unit face the fingertips, and the electrode pads can be rotated to connect with the fixed main unit. Based on the preset left or right hand wearing method, the intelligent recognition unit determines whether the electrode pads are correctly installed. The human-machine interface provides a simple and intuitive wearing guide to assist the user in quickly and correctly wearing the device, greatly improving the user experience. The fixed main unit and electrode pads can be rotated 180° for interchangeable left and right hand wearing, offering high versatility and convenient operation.

[0026] 4. By setting a first magnetic block and a second magnetic block, the two adapters are respectively embedded in the adapter interface and the groove. The first magnetic block and the second magnetic block are attracted and connected, so as to achieve the effect of fixing the host and the electrode sheet bundle for quick installation and connection.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 7 One embodiment of the present invention provides: a wrist-worn nerve stimulator suitable for both left and right hands, comprising,

[0040] The fixed host 20 has grooves 21 and adapters 22 on both sides of its bottom. Multiple PIN points are provided in the adapters 22. The fixed host 20 is equipped with a controller 23, which is electrically connected to the multiple PIN points. The controller 23 includes at least a main control MCU 24, an intelligent recognition unit 25, a storage unit 26, and a stimulation unit 27.

[0041] The storage unit 26 is used to store identification data, preset parameters and usage information data, and the stimulation unit 27 is used to output electrical stimulation. The stimulation intensity can be adjusted according to the preset parameters in the storage unit 26, and then the electrical stimulation is output to the electrode pad bundle 30 through the PIN point in the adapter 22.

[0042] For different types of symptoms, the stimulation unit 27 can output different types of current according to the preset parameters in the storage unit 26. Different types of current have different main physiological effects on the human body. Direct current is a current with a constant direction, which can change the distribution of ions in the body and adjust the body's functions. Low and medium frequency currents stimulate neuromuscular contraction, lower the pain threshold, and relieve adhesions. They are often used for neuromuscular diseases such as injury and inflammation. High frequency current promotes circulation, reduces inflammation and edema, stimulates tissue regeneration, and relieves pain due to its thermal effect on the human body. High-power high frequency current can be used for heating to treat cancer. Static electricity mainly regulates the central nervous system and autonomic function. It is often used for neurosis, early hypertension, menopausal syndrome, etc.

[0043] The electrode strip 30 includes a base 31 and an electrode assembly 32. Adapter seats 33 are located on both sides of the top surface of the base 31. The shapes of the two adapter seats 33 are adapted to the shapes of the groove 21 and the adapter interface 22. A storage IC is housed within the base 31, and the two adapter seats 33 are electrically connected to the storage IC, which contains an independent identification ID. The electrode assembly 32 has multiple electrode pieces 34, and the two adapter seats 33 are electrically connected to the multiple electrode pieces 34. Multiple PIN pins adapted to PIN points are provided on the adapter seats 33. When the electrode strip 30 is used with the fixed host 20, the storage IC can record and save the number of times the electrode strip 30 is used or the duration of use in real time. When the electrode strip 30 is nearing the end of its service life, it can remind the user to replace it in time. If the electrode strip 30 continues to be used after its expiration date, the fixed host 20 will lock the device. After replacing the electrode strip 30, normal use can continue.

[0044] Specifically, the bottom of the fixed host 20 is provided with a plurality of first magnetic blocks 28, which are located on the front and rear sides of the groove 21 and the front and rear sides of the adapter 22, respectively. The base 31 is provided with a plurality of second magnetic blocks 29 that are adapted to the first magnetic blocks 28. Two adapter seats 33 are respectively embedded into the adapter 22 and the groove 21, and the first magnetic blocks 28 and the second magnetic blocks 29 are attracted and connected, realizing the effect of quick installation and connection of the fixed host 20 and the electrode sheet bundle 30.

[0045] Specifically, the adapter 22 has multiple PIN points, which in this embodiment are pins 11, 12, 13, 14, and 15. The adapter 33 has multiple PIN pins. In this embodiment, three electrode pads 34 are provided, namely a common electrode 16, a radial nerve electrode 17, and a median nerve electrode 18. The common electrode 16 is located below the base 31, the radial nerve electrode 17 is located in the middle of the electrode assembly 32, and the median nerve electrode 18 is located at the outermost end of the electrode assembly 32. In this embodiment, the left adapter 33 has 5 pins. The PIN pins are numbered 1, 2, 3, 7, and 8. The right adapter 33 has 5 PIN pins numbered 4, 5, 6, 9, and 10. Pins 1, 2, and 3 of the left adapter 33 and pins 4, 5, and 6 of the right adapter 33 are electrically connected to the radial nerve electrode 17, the common electrode 16, and the median nerve electrode 18, respectively. Pins 7 and 8 of the left adapter 33 and pins 9 and 10 of the right adapter 33 are electrically connected to the storage IC. The fixed host 20 and the electrode sheet bundle 30 are electrically connected through the PIN points and the PIN pins.

[0046] Specifically, the main control MCU 24 on the controller 23 is model NRF52840. This model of controller 23 has the advantage of small size. When installed inside the fixed host 20, it can effectively save the size of the fixed host. The controller 23 simultaneously meets the functions of storing parameters, intelligent identification, current control, human-machine interface control, and Bluetooth transmission. This model of main control MCU 24 can realize the above basic functions and has the best cost performance advantage, further optimizing the price of the overall neurostimulator and improving product competitiveness. The storage IC is model DS2431Q. It has the advantage of small size. When installed inside the electrode pad bundle 30, it can effectively save the size of the electrode pad bundle 30. The storage IC can record the identification ID and usage time. In conjunction with the fixed host 20, it can realize functions such as intelligent identification and lifespan detection. This model of storage IC can realize the above basic functions and has the best cost performance advantage, further optimizing the price of the overall neurostimulator and improving product competitiveness.

[0047] At the factory, a unique ID with specific encoding rules is written into the storage IC. The controller 23 reads the ID number in the storage IC through the interface, decodes it according to the encoding rules, and performs ID verification and recognition. After successful recognition, the usage time can be written into the storage IC for storage.

[0048] Among them, the main control MCU24, model NRF52840, can be connected to control a Bluetooth module (not shown in the figure). This Bluetooth module can wirelessly connect with electronic devices with Bluetooth function. After connecting with electronic devices, wireless data transmission can be performed, including real-time updates of ID number, stimulation parameters, size parameters, etc. in the storage IC, and storage in storage unit 26.

[0049] Among them, the main control MCU24 is connected to the intelligent recognition unit 25, the storage unit 26 and the stimulation unit 27 through PLC programming.

[0050] The storage IC has two pins: GND and SI / O. During normal operation, GND should be at a 0 level, and SI / O should be used for transmitting and receiving data. The GND pin is connected to pins 8 and 10, and the SI / O pin is connected to pins 7 and 9.

[0051] The controller 23 is equipped with IO_1 and IO_2 pins (i.e. pins 15 and 14), and the controller 23 can freely configure the level state and working mode of IO_1 and IO_2.

[0052] Specifically, the intelligent identification unit 25 is used to identify the identification ID in the storage IC. The intelligent identification unit 25 can determine the connection orientation of the electrode strip 30 based on the connection pins of the controller 23 and the storage IC, that is, whether the adapter 22 is connected to the left adapter 33 or the right adapter 33. The connection pin data is stored in the storage unit 26. When the connection pins of the storage IC match the pin data, the fixed host 20 and the electrode strip 30 can be used normally. When the connection pins of the storage IC do not match the pin data, the fixed host 20 and the electrode strip 30 cannot be used, and a fault alarm is issued through the fixed host 20. Wearing instructions are displayed on the human-machine interface on the screen to guide the user to install it in the correct way, ensuring the correctness and safety of the user's use.

[0053] Furthermore, the intelligent identification unit 25 can detect the identification ID stored in the IC, monitor the number of times or duration of use of the electrode pads, and ensure that the electrode pads 30 are from the original manufacturer and within their validity period, thus guaranteeing the stability of use. Because different users have different physical conditions, the required resistance value of the electrode pads 30 varies; wrist diameters also differ, meaning the required size of the electrode pads 34 varies. By using the identification ID stored in the IC, the intelligent identification unit 25 can detect parameters such as resistance and size on the electrode pads 30, and then compare them with the parameters preset by the storage unit 26 to determine whether the user is using an electrode pad 34 that is compatible with them. By selecting an electrode pad 30 that is compatible with them, the user can achieve the best electrotherapy effect.

[0054] Specifically, the fixed host 20 is also equipped with a display screen 35, a control button 36, and a charging interface (not shown). The control button 36 is located on one side of the fixed host 20, the charging interface is used to charge the fixed host 20, the display screen 35 is used to display the human-machine interface of the fixed host 20, and can provide corresponding simple and intuitive wearing guidance diagrams on the human-machine interface to help users wear it quickly and correctly, greatly improving the user experience. The control button 36 is used to control the power on or off of the fixed host 20 and to realize other auxiliary functions.

[0055] When a user wears the wrist-worn neurostimulator, the control button 36 of the fixed host 20 faces the side of the user's fingertips. This wearing method allows the user to see the control button 36 more intuitively and operate the fixed host 20 according to the markings on the control button 36. It is also more convenient and flexible for the user to use, thus improving the user experience.

[0056] Specifically, it also includes an adjustment band 37, the two ends of which are movably connected to both sides of the fixed host 20. The fixed host 20 and the adjustment band 37 form an annular opening. After the user passes through the annular opening, the adjustment band 37 can adjust the size of the annular opening to fit the user's wrist diameter. The electrode pad bundle 30 is attached to the inner wall of the adjustment band 37, and multiple electrode pads 34 are in contact with the user's skin. In this embodiment, the electrode pads 34 are designed according to ergonomics, and the surface of the electrode pads 34 is slightly curved. This slightly curved surface is adapted to the curvature of the human wrist, further improving the fit between the electrode pads 34 and the user's skin, and achieving a better electrotherapy effect.

[0057] refer to Figures 8 to 9 The diagram shows the left hand wearing the wrist-worn neurostimulator. The adapter 33 with pins 1, 2, 3, 7, and 8 is embedded in the adapter interface 22. Pins 1, 2, 3, 7, and 8 of the adapter 33 are connected to pins 11, 12, 13, 15, and 14 of the adapter interface 22, respectively. The intelligent recognition unit 25 can identify whether the controller 23 is connected to pins 7 and 8 of the adapter 33, ensuring that the main unit 20 and the electrode pad strap 30 are installed correctly. The adapter 33 with pins 4, 5, 6, 9, and 10 is embedded in the groove 21, providing insulated contact. The electrode pad strap 30 fits against the right half of the user's wrist.

[0058] When worn correctly, the I0_1 pin of controller 23 outputs a level signal. The I0_1 pin (pin 15) of controller 23 is connected to the SI / O pin (pin 7) on the storage IC for data transmission and reception. At this time, pin 14 (pin I0_2) of controller 23 outputs a 0 level signal, indicating normal communication and confirming that the user's wristband is installed correctly. When worn incorrectly, the I0_1 pin of controller 23 outputs a level signal. The I0_1 pin (pin 15) of controller 23 is connected to the GND pin (pin 8) on the storage IC for data transmission and reception. The level of the GND pin is not 0, indicating that the user's wristband is installed incorrectly, and the host 20 simultaneously issues an alarm signal.

[0059] refer to Figures 10 to 11 The diagram shows the right hand wearing the wrist-worn neurostimulator. The adapter 33 with pins 4, 5, 6, 9, and 10 is embedded in the adapter interface 22. Pins 4, 5, 6, 9, and 10 of the adapter 33 are in contact with pins 13, 12, 11, 14, and 15 of the adapter interface 22, respectively. The intelligent recognition unit 25 can identify whether the controller 23 is connected to pins 9 and 10 of the adapter 33, ensuring that the main unit 20 and the electrode pad strap 30 are installed correctly. The adapter 33 with pins 1, 2, 3, 7, and 8 is embedded in the groove 21, providing insulated contact. The electrode pad strap 30 fits against the left half of the user's wrist.

[0060] When worn correctly, the I0_2 pin of controller 23 outputs a level signal. The I0_2 pin (pin 14) of controller 23 is connected to the SI / O pin (pin 9) on the storage IC for data transmission and reception. At this time, the 15 pin (I0_1 pin) of controller 23 outputs a 0 level signal, indicating normal communication and confirming that the user's wristband is installed correctly. When worn incorrectly, the I0_2 pin of controller 23 outputs a level signal. The I0_2 pin (pin 14) of controller 23 is connected to the GND pin (pin 10) on the storage IC for data transmission and reception. The level of the GND pin is not 0, indicating that the user's wristband is installed incorrectly, and the host 20 simultaneously issues an alarm signal.

[0061] Furthermore, the common electrode 16 outputs a negative current to the user, the radial nerve electrode 17 outputs a positive current to the user, and the median nerve electrode 18 outputs a positive current to the user. By stimulating the user's nerves with different currents, the electrotherapy effect is achieved.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
