Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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 invention.

[0031] Existing wireless electromyographs are usually not completely wireless. The amplifier box and electrodes are connected by lead wires, which are easily interfered by the lead wires, resulting in inaccurate collected electromyographic signals. In addition, since the amplifier box and electrodes are attached to the subject, they affect the subject's activities and make it difficult to collect the electromyographic signals when the subject is exercising.

[0032] The present invention provides a wireless electromyograph, which aims to achieve a completely wire-free connection, and only requires electrodes to be attached to the body, which will not affect the activities of the subject.

[0033] See also Figures 1 to 6In one embodiment of the present invention, the wireless electromyograph 100 includes an amplifier component 1, an electrode component 2 and a data receiving component 3, wherein the amplifier component 1 includes a shell 11 and an amplifier circuit board 13 disposed in the shell 11; the electrode component 2 is used to be attached to the skin to collect electromyographic signals, the amplifier component 1 is disposed on a surface of the electrode component 2 away from the skin, and is electrically connected to the electrode component 2 for amplifying the electromyographic signals; the data receiving component 3 is wirelessly connected to the amplifier component 1 for receiving the amplified electromyographic signals and converting them into digital signals.

[0034] In this embodiment, the electrode assembly 2 is a common electrode sheet on the market, which is used to fit the skin of the subject, and plays a role in connecting the circuit and collecting electromyographic signals. Since the traditional electromyograph uses lead wires to connect the amplifier box and the electrode, these lead wires may be subject to electromagnetic interference, resulting in signal distortion. The present invention directly connects the amplifier assembly 1 with the electrode assembly 2 to achieve a wire-free connection, reducing the possibility of external interference, thereby improving the quality of electromyographic signal collection. In addition, it is only necessary to paste the electrode sheet on the skin surface of the subject, reducing the steps of pasting the amplifier assembly 1 and reducing the area of ​​the skin surface to be pasted, improving comfort, and not affecting the movement of the subject. The wireless connection between the electrode assembly 2 and the amplifier assembly 1 means that data transmission only needs to pass through a shorter physical medium, which may improve the speed and efficiency of data transmission, and also reduce the signal loss caused by the wire connection. The wireless design simplifies the installation and use process of the device, and the user does not need to worry about the management and maintenance of the lead wire, making the device easier to operate. Traditional lead wire connections may be damaged due to pulling, bending or long-term use. Wireless connections reduce these physical connection points, thereby reducing the failure rate of the device.

[0035] The wireless connection between the data receiving component 3 and the amplifying component 1 can be a WiFi connection or a wireless connection such as Bluetooth, so that the subject's range of motion is not limited to the vicinity of the data receiving component 3, enhancing the subject's comfort and freedom of movement, so as to collect more motion-related electromyographic signals. The wireless connection between the data receiving component 3 and the amplifying component 1 means that no physical medium is required for data transmission, which may increase the speed and efficiency of data transmission, while also reducing signal loss caused by physical connection, and reducing the risk of damage to traditional lead wire connections due to pulling, bending or long-term use, thereby increasing the service life of the device.

[0036] The wireless electromyograph 100 proposed in the technical solution of the present invention includes an electrode assembly 2 for being attached to the skin surface, an amplifying assembly 1 wirelessly connected to the electrode assembly 2, and a data receiving assembly 3 wirelessly connected to the amplifying assembly 1. The electrode assembly 2 is attached to the skin surface of the subject and is used to collect the electromyographic signal of the subject. The amplifying assembly 1 receives the electromyographic signal and amplifies it in proportion, and then wirelessly transmits the amplified electromyographic signal to the data receiving assembly 3, which is then converted into a digital signal for subsequent processing.

[0037] The subject, i.e., the electrode assembly 2, is directly connected to the amplifying assembly 1 without any lead wires, which effectively eliminates wire interference and makes the collected data more realistic. Compared with lead wire connection, it is less restricted by distance and has less impact on the subject's movements, so that more electromyographic signals of the subject can be collected during movement.

[0038] In the embodiment of the present invention, the electrode assembly 2 includes a first electrical connection portion 21 and a conductive portion 22, the conductive portion 22 is used to fit the skin, one side of the first electrical connection portion 21 is electrically connected to the conductive portion 22, and the other side is used to penetrate the housing 11 and be electrically connected to the amplifying circuit board 13;

[0039] The amplifying component 1 further includes a second electrical connection portion 12 , one side of which is electrically connected to the amplifying circuit board 13 , and the other side of the second electrical connection portion 12 is partially exposed from the housing 11 for being electrically connected to the first electrical connection portion 21 .

[0040] In this embodiment, the electrode assembly 2 includes a conductive part 22 and a first electrical connection part 21. The conductive part 22 is in contact with the skin to form a current loop to collect electromyographic signals. The first electrical connection part 21 is connected to the conductive part 22 and passes through the housing 11 of the amplifying component 1 to be directly electrically connected to the amplifying circuit board 13 of the amplifying component 1, thereby reducing the loss of electromyographic signals during transmission and helping to ensure a stable connection between the electrode assembly 2 and the amplifying circuit board 13, thereby improving the transmission efficiency and quality of electromyographic signals.

[0041] The design of the second electrical connection portion 12 allows a modular connection between the amplifier assembly 1 and the electrode assembly 2, which means that the two assemblies can be manufactured and maintained relatively independently, which is convenient for upgrading and replacement. One side of the second electrical connection portion 12 is exposed to the housing 11, so that the first electrical connection portion 21 of the electrode assembly 2 can be easily connected thereto, simplifying the assembly process of the entire device.

[0042] In the embodiment of the present invention, the first electrical connection part 21 is a magnetic male buckle, the second electrical connection part 12 is a magnetic female socket, and the first electrical connection part 21 is magnetically connected to the second electrical connection part 12.

[0043] In this embodiment, the magnetic connection allows the user to quickly connect the electrode assembly 2 to the amplifying assembly 1 without complicated plugging and unplugging actions, which is very useful when the equipment needs to be set up quickly. The magnetic connection usually has the characteristic of automatic alignment, which means that even if the user has a slight deviation in the angle when connecting, the magnetic force will guide the two components to align correctly, ensure the accuracy of the connection, and prevent the connection deviation from causing inaccurate or lost signals collected. The magnetic connection between the first electrical connection part 21 and the second electrical connection part 12 provides a stable connection method, which can ensure that the connection between the electrode assembly 2 and the amplifying assembly 1 will not be accidentally disconnected even when the subject is moving. It can be understood that in other embodiments, the first electrical connection part 21 is a magnetic female seat, the second electrical connection part 12 is a magnetic male buckle, and the magnetic female seat and the magnetic male buckle are magnetically connected.

[0044] In an embodiment of the present invention, the amplifying component 1 further includes a rechargeable battery 14 . The rechargeable battery 14 is disposed in the housing 11 and is electrically connected to the amplifying circuit board 13 to supply power to the amplifying circuit board 13 .

[0045] In this embodiment, the amplification component 1 is provided with a rechargeable battery 14, which can be a lithium battery or other types of rechargeable batteries 14, allowing the subject to use the device without an external power supply, reducing the dependence on the external power supply, which greatly improves the portability of the device and makes it more suitable for use in outdoor or mobile environments. The rechargeable battery 14 provides a continuous power supply, allowing the user to use the device for a long time after a single charge, which is particularly important for medical or sports tests that require long-term monitoring. In addition, the use of a rechargeable battery 14 to power the amplification component 1 can eliminate the frequency interference of the mains power and make the collected electromyographic signals more accurate.

[0046] In an embodiment of the present invention, the data receiving component 3 includes a charging box 31 and a charging circuit board. The charging circuit board is disposed in the charging box 31. The charging box 31 is formed with a charging slot 32. The amplifying component 1 can be disposed in the charging slot 32 and electrically connected to the charging circuit board to charge the rechargeable battery 14.

[0047] In this embodiment, the data receiving component 3 includes a charging box 31 and a charging circuit board, which provides a convenient charging platform. The user can place the amplifying component 1 on the charging slot 32 for charging, which simplifies the charging process and can store the amplifying component 1 for the next use. The amplifying component 1 can be electrically connected to the charging circuit board through a PIN pin or through a contact point for charging, and the charging method is not limited here.

[0048] In an embodiment of the present invention, the data receiving component 3 also includes a WiFi receiving unit, which is disposed in the charging box 31, and the amplifying component 1 also includes a WiFi transmitting unit, which is wirelessly connected to the WiFi receiving unit to transmit electromyographic signals.

[0049] In this embodiment, WiFi technology generally provides a higher data transmission rate, which means that the electromyographic signal can be quickly transmitted from the amplifying component 1 to the data receiving component 3, reducing data delay. WiFi technology generally has a longer transmission distance, which allows the amplifying component 1 to move freely within a certain range without losing the connection with the data receiving component 3, which can increase the range of movement of the subject and thus increase the diversity of collected data. Through the WiFi connection, the electromyographic signal can be transmitted to a remote server or monitoring device, making remote medical monitoring and data analysis possible.

[0050] In an embodiment of the present invention, there are multiple electrode assemblies 2, multiple amplifier assemblies 1, one electrode assembly 2 is directly electrically connected to one amplifier assemblies 1, and multiple charging slots 32 are provided. One amplifier assemblies 1 can be disposed in one charging slot 32 and electrically connected to the charging circuit board to charge the rechargeable battery 14.

[0051] In this embodiment, the number of electrode assemblies 2 and amplifying assemblies 1 are both multiple, and one electrode assembly 2 is connected to one amplifying assembly 1, which can realize the simultaneous acquisition of electromyographic signals at multiple positions of the subject, thereby improving efficiency. Correspondingly, the number of charging slots 32 in the charging box 31 is the same as that of the amplifying assemblies 1. An amplifying assembly 1 can be set in a charging slot 32 and electrically connected to the charging circuit board to charge the rechargeable battery 14. The multiple charging slots 32 are arranged in an array in the charging box 31, which can not only realize the charging of multiple amplifying assemblies 1, but also can store multiple amplifying assemblies 1 to prevent omission or loss.

[0052] In the embodiment of the present invention, the wireless electromyograph 100 further includes a data processing component 4, which is communicatively connected to the data receiving component 3 for processing and analyzing digital signals.

[0053] In this embodiment, the data processing component 4 can perform complex processing and analysis on the digital signal transmitted from the amplification component 1, including filtering, signal enhancement, feature extraction, etc., to improve the quality and availability of the signal. The data processing component 4 processes and analyzes the electromyographic signal in real time, providing instant feedback and results to the user or medical professional. Through advanced data processing algorithms, the key features in the electromyographic signal can be more accurately identified and analyzed, thereby improving the accuracy and reliability of diagnosis. The data processing component 4 has six analysis and reporting modes: standard mode, frequency / fatigue, average activity, power spectrum, symmetry, and coordination, which can meet a variety of testing needs. The data processing component 4 can also import and export cases from the case database, which is convenient for doctors to archive and back up cases.

[0054] In the embodiment of the present invention, the wireless electromyograph 100 further includes a display component 5 , which is electrically connected to the data processing component 4 and is used to display the analysis result of the data processing component 4 .

[0055] In this embodiment, the display component 5 can intuitively display the electromyographic signal results analyzed by the data processing component 4, including waveforms, charts, numerical values, etc., so that users can quickly understand the data and provide real-time feedback, which is particularly important for application scenarios that require real-time monitoring of electromyographic signals (such as sports training, rehabilitation treatment, etc.). The display component 5 can interact with the user, such as touch operation, button control, etc., so that the user can adjust the display content and parameters according to their needs.
