Description

Electrode pads and ECG detection devices Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an electrode sheet and an electrocardiogram detection device. Background Art

[0002] ECG electrodes play an important role in various application scenarios such as heart disease examination, cardiac monitoring and cardiac surgery. ECG electrodes are an important component of electrocardiogram testing and can convert heart activity into electrical signals to provide important diagnostic information and help formulate treatment plans.

[0003] ECG electrodes currently on the market fall into two main categories: reusable and disposable. Reusable electrodes are generally dry and require disinfection and humidification before use, such as the clip-on and suction-ball electrodes used in ECG machines. While reusable electrodes are low-cost and easy to use, they can only be used to collect ECG signals for short periods of time and can easily cause cross-infection if not properly disinfected. Disposable electrodes are primarily used for long-term ECG monitoring and offer strong adhesion and excellent conductivity. However, they can be prone to skin allergies. Prolonged use of disposable ECG electrodes can lead to skin allergies and contact dermatitis due to the adhesive on the electrode sheet and the high concentration of electrolytes in the conductive gel. The risk of allergic reactions with disposable ECG electrodes is positively correlated with the duration of application, with the incidence increasing with longer application time. Furthermore, the conductive gel on disposable electrodes can easily fall off with excessive sweating, resulting in poor contact and impaired ECG signal acquisition.

[0004] Although ECG electrodes play an important role in the diagnosis and treatment of heart diseases, frequent replacement of ECG electrodes will result in waste of electrodes and increase expenditure costs.

[0005] The above information disclosed in this Background section is only for enhancement of understanding of the background of the application and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention

[0008] For example, in some embodiments of the present application, the conductive contact unit includes: a conductive cloth for collecting the electrical signal of the object to be measured; the conductive cloth is a fiber structure provided with a conductive material.

[0009] For example, in some embodiments of the present application, the conductive material includes at least one of gold, silver, silver chloride, titanium and graphene.

[0010] For example, in some embodiments of the present application, the conductive cloth is provided with a first groove for storing hydrogel, so that when the conductive cloth is attached to the object to be measured, the hydrogel is used to provide moisture to moisten the conductive cloth and the object to be measured, thereby reducing the contact impedance between the conductive cloth and the object to be measured.

[0011] For example, in some embodiments of the present application, the hydrogel includes: water; or water and vitamin C, hyaluronic acid, sodium pyrrolidonecarboxylate and / or diluted glycerin.

[0012] For example, in some embodiments of the present application, the conductive contact unit further includes: a glue net, one side of which is attached to the outer side of the first groove, and the other side of which is attached to the object to be measured.

[0013] For example, in some embodiments of the present application, when the adhesive mesh is attached to the first groove, the area ratio of the first groove attached to the object to be measured is greater than a first threshold of the bottom area of ​​the first groove.

[0014] For example, in some embodiments of the present application, the isolation sheet includes: an outer layer of plastic, which is bonded to the conductive cloth to seal the hydrogel; an inner layer of plastic, which is arranged between the conductive cloth and the adhesive mesh, and a first hole is provided on the inner layer of plastic so that the first groove can be bonded to the object to be tested after passing through the first hole.

[0015] For example, in some embodiments of the present application, the conductive component includes: a first part and a second part; the conductive cloth is provided with a second hole, and the outer plastic is provided with a third hole, so that the second part passes through the second hole and the third hole and is connected to the first part to fix the conductive contact unit and the isolation plate.

[0016] For example, in some embodiments of the present application, the second hole and the third hole are arranged at a central position or an eccentric position of the conductive contact unit and the isolation sheet.

[0017] For example, in some embodiments of the present application, the fabric includes: a first ring and a second ring, wherein: the area between the first ring and the second ring is a non-glue-coated area; the inner side of the first ring and the outer side of the second ring are glue-coated areas; a sweat ring is arranged between the first ring and the second ring, and is used to drain moisture from the surface of the object to be tested.

[0018] For example, in some embodiments of the present application, the fabric is a unidirectional moisture-conducting fabric.

[0019] For example, some embodiments of the present application further include: a sealing gasket, which is fitted with the fabric and the rubber ring to improve the sealing between the fabric and the rubber ring.

[0020] For example, in some embodiments of the present application, the rubber ring includes: a first rubber ring, which is arranged between the inner layer of plastic and the fabric, and is in contact with the inner layer of plastic of the isolation sheet, the fabric and the sealing gasket; a second rubber ring, which is arranged between the sealing gasket and the release paper assembly, and is in contact with the sealing gasket.

[0021] For example, in some embodiments of the present application, the first rubber ring is provided with a fourth hole; the fabric is provided with a fifth hole; the sealing gasket is provided with a sixth hole; and the second rubber ring is provided with a seventh hole; so that the first groove fits with the object to be measured after passing through the fourth hole, the fifth hole, the sixth hole and the seventh hole.

[0022] For example, in some embodiments of the present application, the diameter of the fifth hole is larger than the diameters of the fourth hole, the sixth hole, and the seventh hole.

[0023] For example, in some embodiments of the present application, the release paper assembly includes: release paper, used to stick the fabric to protect the adhesive layer of the fabric; and a sealing cover, used to stick the rubber ring to protect the moisture of the conductive contact unit.

[0024] According to a second aspect of the present application, at least one embodiment of the present application provides an electrocardiogram detection device, comprising: an electrode sheet as described in any one of the first aspects.

[0025] For example, in some embodiments of the present application, it also includes: a host for processing the electrical signals collected by the electrode sheet.

[0026] The present application provides an electrode sheet with a simple structure. Hydrogel is added to the conductive contact unit to keep the conductive contact unit moist, and the skin impedance can be reduced during use to better collect electrical signals. An adhesive mesh is used to fix the part of the conductive contact unit that contacts the object to be measured to improve the position stability of the electrode sheet. A unidirectional moisture-conducting fabric is used to quickly discharge sweat, thereby improving the comfort of wearing the electrode sheet and reducing the risk of allergies.

[0048] Those skilled in the art will understand that the drawings are merely schematic diagrams of example embodiments, and the modules or processes in the drawings are not necessarily necessary for implementing the present application, and therefore cannot be used to limit the scope of protection of the present application.

[0049] As shown in FIG. 1 and FIG. 2 , the electrode sheet includes a conductive component 1 , an isolation sheet 2 , a conductive contact unit 3 , an adhesive ring 4 , an adhesive ring 7 , a fabric 5 and a release paper component 8 .

[0050] The conductive component 1 is used to fix the isolation sheet 2 and the conductive contact unit 3. The conductive component 1 is also used to connect to a host (not shown in the figure) to transmit the electrical signal collected by the conductive contact unit 3 to the host.

[0051] The conductive contact unit 3 is used to fit the object to be measured to collect electrical signals. For example, the conductive contact unit is fitted to the human body to collect the human body's electrocardiogram signals.

[0052] The conductive contact unit 3 includes a conductive cloth 32 and a plastic mesh 33. The conductive cloth is used to collect electrical signals from the object to be measured.

[0053] According to some embodiments, the conductive fabric is a fiber structure provided with a conductive material, wherein the conductive material includes at least one of gold, silver, silver chloride, titanium, and graphene. The conductive material may be plated on the surface of the fiber structure, for example, silver may be plated on the surface of the conductive fabric, so that the conductive fabric can collect and transmit electrical signals.

[0054] For example, the conductive cloth is 30-50D warp or weft knitted fabric with a gram weight of 90-120g / ㎡, made of silver, with an antibacterial rate of >99% and a surface resistance of <1Ω / cm. At this time, the conductive cloth has good conductive properties, and the material of the conductive cloth has been subjected to antioxidant treatment, which can resist sweat erosion.

[0055] The conductive cloth 32 is provided with a first groove that fits in contact with the object to be measured. This groove is used to store the hydrogel 31. This ensures that when the electrode sheet is in use, moisture from the hydrogel 31 penetrates the conductive cloth 32, keeping both the conductive cloth 32 and the object to be measured moist. This reduces the contact impedance between the conductive cloth and the object to be measured, allowing the electrode sheet to better collect electrical signals and ensuring the accuracy of the signals collected by the conductive contact unit 3.

[0056] According to some embodiments, the hydrogel contains pure water or water and other ingredients with skin-protective properties, such as vitamin C, hyaluronic acid, sodium pyrrolidonecarboxylate, and / or diluted glycerin. The water content of the hydrogel is 50%-90%. This application uses this example only, but the specific water content and ingredients of the hydrogel are not limited to this. The hydrogel provided in this application does not contain electrolytes to reduce the risk of skin allergies in the test subject.

[0057] The adhesive mesh 33 is in the form of double-sided tape, one side of which is attached to the outside of the first groove and the other side is attached to the object to be measured. When the electrode sheet is attached to the object to be measured, the adhesive mesh 33 adheres to the surface of the object to be measured, fixing the electrode sheet to the object to be measured and maintaining the stability of the electrode sheet.

[0058] According to some embodiments, the glue mesh 33 can adopt various shapes. Figures 3A-3D show the shapes of the glue mesh of exemplary embodiments. For example, the glue mesh is in the shape of strips, as shown in Figure 3A; the glue mesh is in the shape of dots, as shown in Figure 3B; the glue mesh is in the shape of a mesh, as shown in Figure 3C; the glue mesh is in the shape of a ring, as shown in Figure 3D; or a combination of the above shapes.

[0059] According to some embodiments, when the adhesive mesh 33 is attached to the first groove, the exposed portion of the first groove, i.e., the area of ​​the portion attached to the object to be measured, must be larger than a first threshold of the bottom area of ​​the first groove to ensure that the conductive fabric 32 can effectively collect electrical signals. The first threshold can be set arbitrarily. For example, the first threshold is 50%, meaning that the area of ​​the portion attached to the object to be measured must be larger than 50% of the bottom area of ​​the first groove.

[0060] The isolation sheet 2 is used to adhere the conductive contact unit 3 to isolate the conductive contact unit from the air.

[0061] The isolation sheet 2 comprises an outer plastic layer 21 and an inner plastic layer 22. The outer plastic layer is bonded to the conductive fabric 32, specifically, the outer plastic layer 21 is positioned above the conductive fabric 32 to seal the fabric 32 and the hydrogel 31 stored within it, allowing the fabric 32 to retain moisture for a longer period of time. The inner plastic layer is positioned between the conductive fabric and the adhesive mesh, specifically, below the conductive contact unit 3 where it bonds to the object to be tested. The inner plastic layer 22 is provided with a first hole, allowing the first groove of the conductive fabric 32 to pass through the hole and bond to the object to be tested.

[0062] As shown in FIG2 , the outer plastic layer 21 is attached to the conductive cloth 32 , the hydrogel 31 is stored in the first groove of the conductive cloth 32 , and a glue net 33 is attached below the first groove of the conductive cloth 32 .

[0063] According to some embodiments, the outer plastic layer 21 and the inner plastic layer 22 may be made of polyvinyl chloride (PVC) or other biocompatible plastics. This application only takes this as an example, but is not limited thereto.

[0064] According to some embodiments, the outer plastic layer 21 and the inner plastic layer 22 may be welded by ultrasonic welding to seal and fix the conductive contact unit 3 .

[0065] The conductive assembly 1 includes a first part 12 and a second part 11. The conductive fabric 32 is provided with a second hole, and the outer plastic layer 21 is provided with a third hole. This allows the second part 11 to pass through the second and third holes and connect to the first part, thereby fixing the conductive contact unit 3 and the isolation sheet 2 and transmitting the electrical signals collected by the conductive contact unit 3 to the host.

[0066] According to some embodiments, the second hole and the third hole on the conductive cloth 32 and the outer plastic layer 21 can be set at an eccentric position, that is, the conductive component 1 is set at an eccentric position, as shown in Figure 1; the second hole and the third hole on the conductive cloth 32 and the outer plastic layer 21 can also be set at a central position, that is, the conductive component 1 is set at a central position, as shown in Figure 4.

[0067] The fabric 5 is provided with a viscose material to fit the object to be measured. The fabric is provided with a fifth hole so that the first groove of the conductive cloth 32 fits the object to be measured through the fifth hole.

[0068] According to some embodiments, the fabric 5 is glued on the surface that contacts the object to be measured.

[0069] According to some embodiments, when the existing electrode sheet is attached to the object to be measured, if the object to be measured sweats a lot, the entire glue-coated side of the electrode sheet contacting the human body will cause the sweat to be unable to be discharged, causing the sweat to be stored in the electrode sheet, causing discomfort to the human body.

[0070] Therefore, the present application proposes providing a first loop and a second loop on the fabric 5, as shown in Figure 5. The inner side of the first loop and the outer side of the second loop are adhesive-coated areas, i.e., adhesive is applied to the inner and outer sides of the first loop; the area between the first and second loops is non-adhesive, i.e., no adhesive is applied between the first and second loops. This allows the electrode sheet to direct moisture away from the surface of the object being tested when attached to it. For example, sweat is directed from the side attached to the object being tested to the side facing away from the object being tested.

[0071] According to some embodiments, a sweat ring is further provided on the fabric 5, as shown in Figure 5, and the sweat ring is provided between the first ring and the second ring. The sweat ring is used to guide sweat from the surface in contact with the object to be tested to the surface away from the object to be tested, so as to reduce the risk of allergies of the object to be tested when using the electrode sheet.

[0072] According to some embodiments, the fabric 5 is a unidirectional moisture-conducting fabric, so that when the electrode sheet is attached to the object to be measured, sweat can be conducted from the surface attached to the object to be measured to the surface away from the object to be measured, thereby improving the comfort of using the electrode sheet.

[0073] According to some embodiments, the fabric 5 is made of cotton, linen, silk, and mixed chemical fibers. When the electrode sheet is used for a short time, conventional materials such as non-woven fabrics and foam can also be used to reduce the production cost of the electrode sheet.

[0074] According to some embodiments, the electrode sheet may further include a sealing gasket 6. The sealing gasket 6 is fitted with the fabric 5, the rubber ring 4 and the rubber ring 7 to ensure sealing between the sealing gasket 6 and the rubber ring 4 and the rubber ring 7.

[0075] According to some embodiments, the sealing pad 6 is made of biocompatible plastic and is provided with a sixth hole, so that the first groove of the conductive cloth 32 fits with the object to be tested through the sixth hole.

[0076] The rubber rings of the present application include a first rubber ring 4 and a second rubber ring 7, which are used to secure the fabric 5 and the sealing gasket 6. The first rubber ring 4 is made of double-sided tape and is positioned between the inner plastic layer 22 and the fabric 5 to connect the inner plastic layer 22, the fabric 5, and the sealing gasket 6. The second rubber ring 7 is made of double-sided tape and is positioned between the sealing gasket 6 and the release paper assembly 8 to adhere to the sealing gasket 6. The first rubber ring 4 is provided with a fourth hole, and the second rubber ring 7 is provided with a seventh hole, so that the first groove of the conductive fabric 32 can pass through the fourth and seventh holes to adhere to the object to be tested.

[0077] According to some embodiments, as shown in Figures 6A and 6B, the diameter of the fifth hole of fabric 5 is greater than the diameter of the fourth hole of first rubber ring 4, which is equal to the diameter of the seventh hole of second rubber ring 7, which is equal to the diameter of the sixth hole of sealing gasket 6. Hole 2 is the fifth hole of fabric 5, hole 1 is the fourth hole of first rubber ring 4 or the seventh hole of second rubber ring 7, and hole 3 is the sixth hole of sealing gasket 6. The outer diameters of rubber ring 4, sealing gasket 6, and rubber ring 7 are identical and consistent with the size of the first ring of fabric 5. A small hole is provided in fabric 5 between the first ring and the fifth hole, so that a portion of rubber ring 4 passes through the fifth hole of fabric 5 to bond with sealing gasket 6, while a portion passes through the small hole in fabric 5 to bond with sealing gasket 6, thereby ensuring the reliability and sealing of the bonding between rubber ring 4, fabric 5, and sealing gasket 6. As shown in Figure 5, the small hole in fabric 5 refers to the small hole on the inside of the first ring.

[0078] Thus, the inner plastic layer 22, the first rubber ring 4, the fabric 5, the sealing gasket 6 and the second rubber ring 7 are combined and bonded to form a sealed space.

[0079] The release paper assembly 8 is bonded to the conductive contact unit 3, the fabric 5, and the second rubber ring 7 to form a sealed space to keep the conductive contact unit moist. The release paper assembly 8 includes a release paper 81 and a sealing cover 82. The release paper 81 is attached to the fabric 5 to protect the adhesive layer on the fabric 5. The release paper 81 can be easily removed when the electrode sheet is in use. The sealing cover 82 is used to cover the conductive contact unit 3 and is attached to the second rubber ring 7, forming a sealed space around the electrode sheet to prevent moisture in the hydrogel 31 from evaporating and protect the moisture in the conductive contact unit.

[0080] According to some embodiments, the sealing cover 82 is welded to the release paper 81. The sealing cover 82 is made of plastic PE or PET.

[0081] The present application provides an electrode sheet with a simple structure. Hydrogel is added to the conductive contact unit to keep the conductive contact unit moist, and the skin impedance can be reduced during use to better collect electrical signals. An adhesive mesh is used to fix the part of the conductive contact unit that contacts the object to be measured to improve the position stability of the electrode sheet. A unidirectional moisture-conducting fabric is used to quickly discharge sweat, thereby improving the comfort of wearing the electrode sheet and reducing the risk of allergies.

[0082] As shown in Figure 7A, it is a front view of the electrode sheet, that is, the side facing away from the object to be measured; as shown in Figure 7B, it is a back view of the electrode sheet, that is, the side facing the object to be measured; as shown in Figure 7C, it is a schematic diagram of the side facing the object to be measured after removing the release paper component.

[0083] The present application also provides an electrocardiogram (ECG) detection device for collecting ECG signals from an object to be detected. As shown in FIG8 , the ECG detection device includes the electrode sheet 100 described above and a host computer 300 . The electrode sheet is connected to the host computer, and the host computer 300 is used to process the electrical signals collected by the electrode sheet 100 .

On the contrary, based on the teaching of the content disclosed in this application, these principles can be applied to many other embodiments.
