[0023] DETAILED DESCRIPTION

[0024] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0025] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions that can be implemented in this application, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in this application without affecting the effects and purposes that can be achieved by this application. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of narration, and are not used to limit the scope of the implementation of this application. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of this application without substantial changes in the technical content.

[0026] like Figures 1 to 5 As shown, the present application provides an electrode belt, including a flexible belt body 1, which can be bent and have its two ends connected together, and a first electrode group 2 and a second electrode group 3 are provided on the flexible belt body 1, and the first electrode group 2 and the second electrode group 3 each include a plurality of electrodes 4 arranged at equal intervals along the length direction of the flexible belt body 1, and the number of electrodes 4 in the first electrode group 2 and the second electrode group 3 is equal; there is an avoidance section 5 between the first electrode group 2 and the second electrode group 3 where no electrode 4 is provided, and when the electrode belt is worn by a patient, the avoidance section 5 covers the skin surface of the patient's spine; the electrode 4 is pressed from a conductive cloth and a conductive foam, and the electrode 4 protrudes toward the side of the flexible belt body 1 in contact with the patient's skin.

[0027] like Figure 1 and Figure 2As shown, in an electrode belt of the present application, since an avoidance section 5 is provided between the first electrode group 2 and the second electrode group 3, the design of the avoidance section 5 avoids the contact between the electrode 4 and the spine, thereby reducing the signal interference caused by the poor fit and contact between the protruding uneven structure of the human spine and the electrode 4, and reducing the problem of unstable signal transmission or insufficient accuracy; the length of the avoidance section 5 is determined according to the collected human spine width data, and in order to adapt to different groups of people, the avoidance section 5 can be made of fabric with good elasticity. The electrode 4 of the electrode belt protrudes toward the side of the flexible belt body 1 that contacts the patient's skin to ensure stable contact with the skin, further improving the quality and stability of signal acquisition.

[0028] The flexible belt body 1 of an electrode belt of the present application is elastic and can be made of waterproof insulating elastic fabric. For example, the flexible belt body 1 can be made of a polymer waterproof and breathable material (PTFE membrane) plus a cloth composite fabric. Such a material has good skin-friendliness and a simple manufacturing process, unlike other elastic polymers (such as silicone, TPE, etc.) that require molds to be produced. Since the flexible belt 1 can be bent and connected together to form a closed loop, this design helps to maintain the stable position of the electrode 4 when the patient is moving, reducing signal distortion caused by movement; the protruding design of the electrode 4 ensures close contact with the skin, reducing safety hazards caused by poor contact, such as signal interruption or instability; the design of the avoidance section 5 allows the electrode 4 to avoid the patient's spine when the electrode belt is worn, avoiding the protrusion of the spine that causes the electrode 4 to fit poorly with the skin at the spine, resulting in poor signal and potential interference with the ECG signal, so this design improves the clarity of the signal; the combination of conductive cloth and conductive foam not only provides good conductive properties, but also enhances the contact between the electrode 4 and the skin, which helps to improve the transmission quality and stability of the signal; the electrodes 4 in the first electrode group 2 and the second electrode group 3 are arranged at equal intervals, so that the electrodes 4 arranged in this way can evenly collect ECG signals to ensure signal consistency and accuracy.

[0029] In order to facilitate patients to wear an electrode belt of the present application, such as Figure 4 As shown, a midpoint mark 6 is provided in the middle of the avoidance section 5. The midpoint mark 6 provides a clear reference point for the wearer or medical professional to help them correctly wear the electrode belt at the appropriate position on the patient's body and ensure the accurate distribution of the electrodes 4, thereby improving the accuracy of ECG signal acquisition.

[0030] In order to make the electrode 4 contact well with the patient's skin and maintain good conductivity, each electrode 4 is made of conductive cloth at the contact part with the human body to ensure good contact with the patient's skin. As a preferred embodiment, the electrode 4 includes an outer conductive cloth for contacting the patient's skin, and the inner side of the outer conductive cloth is filled with foam cotton. In this way, the direct contact between the outer conductive cloth and the patient's skin improves the conductivity and ensures the effective collection of the ECG signal. The foam cotton filled on the inner side of the outer conductive cloth provides a soft buffer layer for the wearer, reducing the foreign body sensation and discomfort caused by skin pressure. Moreover, the foam cotton has good elasticity, so that the outer conductive cloth keeps the expanded protrusion state, thereby ensuring the good contact between the outer conductive cloth of the electrode and the patient's skin, maintaining good conductivity, and helping to improve the transmission quality and stability of the signal. The conductive cloth can be a silver-plated cloth or a micro-metal cloth. The silver-plated cloth and the micro-metal cloth have excellent conductivity, which helps to capture and transmit ECG signals more accurately. Silver-plated cloth can resist oxidation and wear due to the high corrosion resistance of silver, extending the service life of the electrode belt. Micro-metal cloth also has good durability due to its structural stability. The low impedance characteristics of silver-plated cloth and micro-metal cloth help reduce signal attenuation and provide clearer and more accurate ECG signals. In addition, silver-plated cloth has antibacterial properties, which helps reduce the risk of skin infection. Micro-metal cloth generally has good biocompatibility, reducing patients' allergic reactions to materials.

[0031] In the technical solution of the present application, the flexible belt body 1 of the electrode belt is made of conductive fabric material, which has lower resistance and smaller impedance, effectively improving the efficiency of signal transmission, thereby improving the signal-to-noise ratio and ensuring the accuracy and stability of the monitoring data. The material properties of the conductive fabric determine that it has a low resistance and can transmit signals more effectively. Therefore, the electrode belt of the technical solution of the present application has a better signal-to-noise ratio and can provide more reliable monitoring data.

[0032] To facilitate the fixation of the electrode belt on the patient's body, Figure 1 and Figure 2 As shown, a connection belt 7 is provided at one end of the flexible belt body 1, and a plurality of fixing buckle holes 8 are provided on the connection belt 7, and a fixing buckle 9 for connecting the fixing buckle hole 8 is provided at the other end of the flexible belt; the design of the connection belt 7 and the fixing buckle 9 allows the user to easily adjust the tightness of the electrode belt according to their body shape, ensuring that it is comfortable to wear and fits the body; the plurality of fixing buckle holes 8 provide a variety of adjustment options, so that the electrode belt can adapt to chest circumferences of different sizes, increasing the range of applicable people. The connection belt 7 and the fixing buckle 9 at both ends of the electrode belt can adopt a hard buckle structure to ensure that the belt will not loosen or fall off during use, and the buckle design can make it more convenient to wear.

[0033] In the technical solution of the present application, the electrode 4 and the flexible belt 1 are detachably connected or fixedly connected, for example, they can be detachably connected by a buckle structure, or they can be fixedly connected by gluing, hot pressing or sewing; as another preferred embodiment, the electrode 4 is fixedly connected with a metal snap, or fixedly connected with a wire, and the metal snap or the wire is used to connect the cable.

[0034] like Figure 3-1 and Figure 3-2 As shown, the electrode 4 is fixedly connected with a metal snap button 10 such as a snap button structure, or is fixedly connected with a wire 10' for an external cable 11. The electrodes 4 can be distributed at a certain interval and can be fixed on the flexible belt body 1 as a whole. The fixing method can be gluing, hot pressing or sewing, etc., and can also be made into an independent body and detachably connected to the flexible belt body 1 through a buckle structure.

[0035] In order to facilitate the replacement of the electrode 4, the electrode 4 and the flexible belt body 1 in the electrode belt are detachably connected through a buckle structure. When the electrode 4 needs to be replaced, the user does not have to replace the entire electrode belt, which helps to extend the service life of the electrode belt and reduce replacement costs.

[0036] like Figure 5 The figure shows an example of connecting the electrode 4 with the wire 10'. The wires of the electrodes 4 of the flexible belt 1 are respectively connected with the cables 11. The cables 11 connected with the electrodes 4 in the first electrode group 2 are integrated and connected to the first data acquisition connector 12, and the cables 11 connected with the electrodes 4 in the second electrode group 3 are integrated and connected to the second data acquisition connector 13. In this way, the signal cables 11 of the electrodes 4 are integrated into the data acquisition connector, which simplifies the overall wiring and reduces the possibility of cable clutter and entanglement.

[0037] The number of electrodes 4 in the electrode belt can be customized according to different application scenarios or user needs, and electrode groups with different layouts and corresponding data acquisition connectors can be customized. In the technical solution of the present application, there are 8 electrodes 4 in each of the first electrode group 2 and the second electrode group 3, and each electrode 4 is numbered to facilitate the corresponding connection of the cable 11 thereto. The present application provides an electrode belt that uses elastic cloth to connect electrodes, while common electrode belts on the market usually use silicone materials. In the technical solution of the present application, the cloth is more comfortable and avoids the discomfort and allergic reactions that may be caused by silicone. Compared with disposable ECG electrodes, in the technical solution of the present application, the electrode belt uses reusable materials, which reduces the cost of use and reduces resource waste. In the technical solution of the present application, the electrodes in the electrode belt use conductive cloth, which is more conductive, has lower impedance, is lighter, and has no foreign body sensation than the common conductive silicone on the market. Disposable ECG electrodes on the market are bonded with glue, which can easily cause discomfort to patients. In the technical solution of the present application, the electrodes can be distributed at a certain interval and can be fixed on the flexible belt body as a whole. The fixing method can be gluing, hot pressing or suture, etc., or it can be made into an independent body, which can be detachably connected to the flexible belt body through a buckle structure, so that when the electrode needs to be replaced, the user does not have to replace the entire electrode belt, which helps to extend the service life of the electrode belt and reduce replacement costs. In the technical solution of the present application, the electrodes are fixedly connected with metal snaps or wires, so that the electrodes and the cables are more secure and reliable, not easy to loosen or fall off, and the stability of the product is improved.

[0038] The electrode belt involved in the present application can be applied to application scenarios including but not limited to monitoring of electrocardiogram signals, lung or other human organ impedance signals, etc., which require multi-point monitoring of human body impedance imaging technology.

[0039] Based on the technical solutions of the above embodiments, an electrode belt of the present application enables the electrode to fit better with the patient's skin, reduces signal interference caused by poor fit between the protruding uneven structure of the body's spine and the electrode, and reduces the problem of unstable signal transmission or insufficient accuracy; the electrode of the electrode belt protrudes toward the side where the flexible belt body contacts the patient's skin to ensure stable contact with the skin, further improving the quality of signal acquisition, and improving the quality of electrocardiogram or pulmonary impedance imaging and the accuracy of diagnosis.

[0040] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0041] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
