Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] This utility model embodiment provides an electrode strip, see reference. Figure 1-4 The electrode strip includes a connecting strip 1 and multiple electrode assemblies 2; the connecting strip 1 includes multiple mounting portions 11 and multiple connecting portions 12, which are arranged alternately; each mounting portion 11 is provided with a mounting hole 13, and the electrode assembly 2 is installed in the mounting hole 13; the width of the mounting portion 11 along the width direction of the electrode strip is greater than the width of the connecting portion 12 along the width direction of the electrode strip.

[0030] As an example, the electrode strip includes a connecting strip 1 and multiple electrode assemblies 2. During installation, the multiple electrode assemblies 2 are arranged at intervals on the connecting strip 1. Specifically, the connecting strip 1 includes multiple mounting parts 11 and multiple connecting parts 12, which are arranged alternately. Each mounting part 11 is provided with a mounting hole 13, and the electrode assembly 2 is installed in the mounting hole 13. This arrangement facilitates the installation of the electrode assembly 2 on the connecting strip 1 and facilitates the disassembly and replacement of the electrode assembly 2 when it is damaged. The width of the mounting portion 11 along the width direction of the electrode strip is greater than the width of the connecting portion 12 along the width direction of the electrode strip. With this configuration, two adjacent mounting portions 11 are connected by a connecting portion 12. The connecting strip 1 between two electrode assemblies 2 is narrower than the connecting strip 1 at the location of the electrode assembly 2. When the position of the electrode assembly 2 is adjusted, the connecting strip 1 between the two electrode assemblies 2, i.e., the connecting portion 12, is easy to bend and will not wrinkle or detach from the human body to be detected. Multiple mounting portions 11 and multiple connecting portions 12 cooperate to form an ergonomically designed connecting strip 1. When the electrode strip contacts the human body to be detected, adjusting the angle of the electrode strip can ensure that the electrode strip is perpendicular to the human body to be detected and fits tightly, improving the fit of the electrode strip when in contact with the human body to be detected, avoiding impedance fluctuations, and ensuring the imaging effect and accuracy. The electrode strip in this example has good adhesion and stable impedance value, and can be used with electrical impedance imaging devices with different functions. The electrical impedance imaging device sends a signal to the part of the human body to be detected through the electrode assembly 2. By alternately exciting two of the electrode assemblies 2 and measuring the potential difference between the other electrode assemblies 2, data for generating images is obtained, providing an important basis for disease diagnosis.

[0031] In one embodiment, the electrode strip is a disposable electrode strip.

[0032] As an example, the electrode strips are disposable. This design ensures that each electrode strip is individually sterile packaged, requires no sterilization, and eliminates the risk of cross-infection. The materials used are environmentally friendly, non-toxic, and harmless to the human body, meeting medical-grade biocompatibility requirements. Compared with existing reusable electrode strips, it is more hygienic, convenient, and has lower production costs.

[0033] In one embodiment, reference is made to Figure 1 The junction of the mounting part 11 and the connecting part 12 is an outward-facing arc-shaped chamfer 14.

[0034] As an example, the junction of the mounting part 11 and the connecting part 12 is an outward-facing arc-shaped chamfer 14. This design improves the flexibility of the connecting strip 1 between two adjacent electrode assemblies 2. When adjusting the position of the electrode assembly 2, the connecting strip 1, i.e., the connecting part 12, between the two electrode assemblies 2 is easy to bend without wrinkling or detaching from the human body to be detected. Multiple mounting parts 11 and multiple connecting parts 12 cooperate to form an ergonomically designed connecting strip 1. When the electrode strip contacts the human body to be detected, adjusting the angle of the electrode strip ensures that the electrode strip is perpendicular to the human body to be detected and fits tightly, improving the fit when the electrode strip contacts the human body to be detected, avoiding impedance fluctuations, and ensuring the imaging effect and accuracy.

[0035] In one embodiment, reference is made to Figure 3 and Figure 4 The electrode assembly 2 includes a bottom buckle 21 and a male buckle 22. The bottom buckle 21 is disposed on the first side of the connecting band 1, and one end of the bottom buckle 21 extends through the mounting hole 13 to the outside of the second side of the connecting band 1. The male buckle 22 is mounted on one end of the bottom buckle 21 and contacts the second side of the connecting band 1.

[0036] As an example, electrode assembly 2 includes a bottom buckle 21 and a male buckle 22. During installation, the bottom buckle 21 is placed on the first side of the connecting band 1, and one end of the bottom buckle 21 extends through the mounting hole 13 to the outside of the second side of the connecting band 1. Specifically, the bottom buckle 21 includes a main body plate 211 and a connecting post 212 extending from the middle of one side of the main body plate 211 along the axial direction of the main body plate 211. The main body plate 211 is installed on the first side of the connecting band 1, and one end of the connecting post 212 extends through the mounting hole 13 to the outside of the second side of the connecting band 1. The male buckle 22 is installed on one end of the bottom buckle 21, i.e., one end of the connecting post 212, and contacts the second side of the connecting band 1. With this arrangement, the bottom buckle 21 and the male buckle 22 are installed on the connecting band 1 by a snap-fit ​​method, which facilitates the installation of the electrode assembly 2 on the connecting band 1 and facilitates the disassembly and replacement of the electrode assembly 2 when it is damaged.

[0037] In one embodiment, reference is made to Figure 4 The electrode strip also includes multiple conductive adhesives 3; each conductive adhesive 3 is disposed on a mounting part 11, located on the first side of the connecting strip 1, and wraps the electrode assembly 2 on the mounting part 11.

[0038] As an example, the electrode strip also includes conductive adhesive 3. During installation, each piece of conductive adhesive 3 is placed on a mounting part 11, located on the first side of the connecting strip 1, and wraps around the electrode assembly 2 on the mounting part 11. This arrangement utilizes the properties of the conductive adhesive 3 to adhere the electrode assembly 2 of the electrode strip to the area to be tested on the human body, ensuring better adhesion of the electrode strip to the skin and reducing impedance fluctuations. The precise control of the conductive adhesive 3's dimensions according to actual needs effectively keeps the impedance value within a very small fluctuation range, resulting in stable impedance that facilitates the acquisition of biosignals or data. The conductive adhesive 3 is made of hydrogel, which is very soft and adheres better to the skin, preventing skin damage from prolonged contact with the adhesive 3. It can also repair damaged skin, reducing user discomfort.

[0039] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The electrode strip also includes release paper 4, which is bonded to conductive adhesive 3.

[0040] As an example, the electrode strip also includes release paper 4. During installation, the release paper 4 is adhered to the conductive adhesive 3, protecting the conductive adhesive 3 from contamination due to air exposure. When the release paper 4 is manually pulled out, it can be quickly and cleanly separated from the conductive adhesive 3. At least a portion of the release paper 4 is exposed outside the edge of the connecting strip 1; this allows the point of force for tearing off the release paper 4 to be found using the exposed portion outside the edge of the connecting strip 1. It should be noted that the point of force can also be called the point of application or the point of force application. Directional markings are printed on the portion of the release paper 4 exposed outside the edge of the connecting strip 1, allowing for easy tearing off of the release paper 4 according to the directional markings.

[0041] In one embodiment, reference is made to Figure 1-4 The electrode strip also includes multiple bonding elements 5; each bonding element 5 is disposed on a mounting portion 11, located on the first side of the connecting strip 1, and surrounds the conductive adhesive 3 on the mounting portion 11.

[0042] As an example, the electrode strip also includes multiple adhesive pieces 5. During installation, each adhesive piece 5 is mounted on a mounting portion 11, located on the first side of the connecting strip 1, and surrounds the conductive adhesive 3 on the mounting portion 11. Specifically, the adhesive piece 5 is mounted on a mounting portion 11, located on the first side of the connecting strip 1. A through groove is provided on the adhesive piece 5, the central axis of which coincides with the central axis of the electrode assembly 2. The conductive adhesive 3 is then filled into the through groove and wrapped around the electrode assembly 2. This configuration allows for better adhesion between the electrode strip and the skin when the connecting strip 1 is bonded to the skin via the conductive adhesive 3, facilitating the installation and use of the electrode strip. Simultaneously, release paper 4 is also bonded to the adhesive piece 5, protecting the conductive adhesive 3 from contamination due to air exposure. The adhesive piece 5 is made of high-density foam coated with a medical-grade, biocompatible adhesive substance that acts directly on the skin, reducing impedance changes caused by gaps and ensuring the accuracy of the test results.

[0043] In one embodiment, reference is made to Figure 2 The bonding component 5 has a ring structure, and the central axis of the ring structure coincides with the central axis of the conductive adhesive 3.

[0044] As an example, the first structural form of the bonding component 5 is introduced, which is a ring structure. During installation, the bonding component 5 is installed on the first side of the connecting strip 1, and the central axis of the ring structure is aligned with the central axis of the conductive adhesive 3. The entire ring structure makes the electrode strip fit better with the skin surface of the human body, which facilitates the installation and use of the electrode strip, reduces the change in impedance value caused by gaps, and ensures the accuracy of the test results.

[0045] In one embodiment, the bonding element 5 is a plurality of arc-shaped structures, which are distributed in a ring-shaped interval around the central axis of the conductive adhesive 3.

[0046] As an example, a second structural form of the bonding component 5 is introduced, which is a plurality of arc-shaped structures. The plurality of arc-shaped structures are distributed in a ring-like interval around the central axis of the conductive adhesive 3. The combination of the plurality of arc-shaped structures makes the electrode strip fit better with the skin surface of the human body, providing convenience for the installation and use of the electrode strip, reducing the change in impedance value caused by gaps, and ensuring the accuracy of the test results.

[0048] As an example, the electrical impedance tomography device includes an electrode strip; the electrode strip includes a connecting strip 1 and a plurality of electrode assemblies 2, which are arranged at intervals on the connecting strip 1 during installation; specifically, the connecting strip 1 includes a plurality of mounting portions 11 and a plurality of connecting portions 12, which are arranged alternately; each mounting portion 11 is provided with a mounting hole 13, and the electrode assembly 2 is installed in the mounting hole 13. This arrangement facilitates the installation of the electrode assembly 2 on the connecting strip 1 and facilitates the disassembly and replacement of the electrode assembly 2 when it is damaged. The width of the mounting portion 11 along the width direction of the electrode strip is greater than the width of the connecting portion 12 along the width direction of the electrode strip. With this configuration, two adjacent mounting portions 11 are connected by a connecting portion 12. The connecting strip 1 between two electrode assemblies 2 is narrower than the connecting strip 1 at the location of the electrode assembly 2. When the position of the electrode assembly 2 is adjusted, the connecting strip 1 between the two electrode assemblies 2, i.e., the connecting portion 12, is easy to bend and will not wrinkle or detach from the human body to be detected. Multiple mounting portions 11 and multiple connecting portions 12 cooperate to form an ergonomically designed connecting strip 1. When the electrode strip contacts the human body to be detected, adjusting the angle of the electrode strip can ensure that the electrode strip is perpendicular to the human body to be detected and fits tightly, improving the fit of the electrode strip when in contact with the human body to be detected, avoiding impedance fluctuations, and ensuring the imaging effect and accuracy.
