Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to an electrode pad and an electrocardiogram (ECG) detection device. Background Technology
[0002] ECG electrodes play an important role in various applications such as cardiac examination, cardiac monitoring, and cardiac surgery. ECG electrodes are an important component of electrocardiogram (ECG) testing, which can convert cardiac activity into electrical signals to provide important diagnostic information and help develop treatment plans.
[0003] Currently, ECG electrodes on the market are mainly divided into two categories: reusable electrodes and disposable electrodes. Reusable electrodes are generally dry electrodes, requiring sterilization and humidification before use, such as the clip-on and bulb-type electrodes used in ECG machines. Although reusable electrodes are low-cost and easy to operate, they can only be used for short-term ECG signal acquisition, and are prone to cross-infection if sterilization is insufficient. Disposable electrodes are mainly used for long-term ECG monitoring, and are firmly attached with good conductivity. However, disposable electrodes are prone to causing skin allergies. Furthermore, prolonged use of disposable ECG electrodes can cause skin allergies and contact dermatitis due to the high concentration of electrolytes in the adhesive and conductive gel on the electrode pads. The risk of allergic reactions to disposable ECG electrodes is positively correlated with the application time; the longer the application time, the higher the incidence. In addition, the conductive gel on disposable electrodes is prone to detachment when exposed to heavy sweating, which can cause poor contact and affect ECG signal acquisition.
[0004] Although ECG electrodes play an important role in the diagnosis and treatment of heart disease, frequent replacement of ECG electrodes will result in waste of electrode pads and increase expenses.
[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] For example, in some embodiments of this application, the conductive material includes at least one of gold, silver, silver chloride, titanium, and graphene.
[0010] For example, in some embodiments of this application, the conductive cloth is provided with a first groove for storing hydrogel, so that when the conductive cloth is attached to the object under test, the hydrogel is used to provide moisture to wet the conductive cloth and the object under test, thereby reducing the contact resistance between the conductive cloth and the object under test.

[0012] For example, in some embodiments of this application, the conductive contact unit further includes: an adhesive mesh, one side of which is attached to the outside of the first groove and the other side of which is attached to the object to be tested.
[0013] For example, in some embodiments of this application, when the adhesive mesh is attached to the first groove, the area ratio of the first groove to the object under test is greater than a first threshold value of the bottom area of the first groove.
[0014] For example, in some embodiments of this application, the insulating sheet includes: an outer plastic layer that is bonded to the conductive cloth to seal the hydrogel; and an inner plastic layer disposed between the conductive cloth and the adhesive mesh, wherein the inner plastic layer has a first hole so that the first groove passes through the first hole and is bonded to the object to be tested.
[0015] For example, in some embodiments of this 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 layer is provided with a third hole, so that the second part passes through the second hole and the third hole and connects with the first part to fix the conductive contact unit and the insulating sheet.
[0016] For example, in some embodiments of this application, the second hole and the third hole are disposed at the center or off-center of the conductive contact unit and the insulating sheet.
[0017] For example, in some embodiments of this application, the fabric includes: a first loop and a second loop, wherein: the area between the first loop and the second loop is a non-adhesive area; the inner side of the first loop and the outer side of the second loop are adhesive areas; and a wicking ring, disposed between the first loop and the second loop, is used to wick moisture away from the surface of the object to be tested.
[0018] For example, in some embodiments of this application, the fabric is a unidirectional moisture-wicking fabric.
[0019] For example, in some embodiments of this application, a sealing gasket is further included, which is fitted to the fabric and the rubber ring to improve the sealing between the fabric and the rubber ring.

[0022] For example, in some embodiments of this 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 this application, the release paper assembly includes: release paper for attaching the fabric to protect the adhesive layer of the fabric; and a sealing cap for attaching the adhesive ring to protect the conductive contact unit from moisture.

[0025] For example, in some embodiments of this application, it further includes: a host computer for processing the electrical signals collected by the electrode sheet.
[0026] [Beneficial Effects]
[0027] The electrode sheet provided in this application, through a multi-component collaborative design, achieves the following beneficial effects:
[0028] Improving the accuracy of electrical signal acquisition: The first groove of the conductive cloth contains hydrogel without electrolytes, which can wet the conductive cloth and the object under test and reduce contact resistance; at the same time, when the electrode sheet is fixed by the adhesive mesh, it ensures the effective contact area between the first groove and the object under test, thus providing double protection for the stability and accuracy of electrical signal acquisition.
[0029] Reduced risk of skin allergies: The hydrogel does not contain high concentrations of electrolytes, and the fabric adopts a zoned adhesive coating design (non-adhesive area + sweat-wicking ring) and is a one-way moisture-wicking material, which can quickly wick away sweat and reduce the irritation of the skin by adhesives and sweat, thus solving the problem of existing disposable electrodes easily causing allergies and contact dermatitis.
[0030] Enhanced electrode stability and durability: The mesh secures the electrode pads with double-sided adhesive, improving positional stability during wear and preventing displacement; the separator, double rubber rings, sealing gasket, and release paper assembly form a sealed space, effectively maintaining the humidity of the conductive contact unit, extending the electrode pad's lifespan, and reducing waste caused by frequent replacements.
[0031] Improve wearing comfort: One-way moisture-wicking fabric with sweat-wicking rings can quickly wick away sweat from the skin surface and prevent sweat buildup; the fabric material can be skin-friendly materials such as cotton and linen, further improving the comfort of wearing for a long time.
[0032] Highly adaptable structure and reliable installation: The holes of the conductive components can be set in the center or off-center position to adapt to different usage scenarios; the hole diameter design and bonding method of the rubber ring, fabric, and sealing gasket ensure the sealing and reliability of the connection of each component, resist sweat corrosion, and adapt to the needs of long-term ECG monitoring.
[0033] Optimized conductivity and antibacterial effect: The conductive cloth uses high-quality conductive materials such as gold, silver, and silver chloride, which have low surface resistance and excellent conductivity. Some materials (such as silver) have an antibacterial rate of >99%. After anti-oxidation treatment, it can resist sweat corrosion and extend its service life.
[0034] Expanding applicable scenarios and reducing usage costs: The electrode pads cater to both short-term and long-term monitoring needs, eliminating the need for frequent replacements. This avoids the risk of cross-infection from reusable electrodes and reduces the waste of disposable electrodes, thus lowering the overall usage cost. The accompanying ECG monitoring device can efficiently process signals and is suitable for various scenarios such as cardiac examinations and cardiac monitoring.

[0057] Those skilled in the art will understand that the accompanying drawings are merely schematic diagrams of exemplary embodiments, and the modules or processes in the drawings are not necessarily essential for implementing this application, and therefore cannot be used to limit the scope of protection of this application.
[0058] like Figure 1 and Figure 2 As shown, the electrode sheet includes a conductive assembly 1, an insulating sheet 2, a conductive contact unit 3, a rubber ring 4, a rubber ring 7, a fabric 5, and a release paper assembly 8.
[0059] The conductive assembly 1 is used to fix the insulating plate 2 and the conductive contact unit 3. The conductive assembly 1 is also used to connect to the host (not shown in the figure) to transmit the electrical signals collected by the conductive contact unit 3 to the host.
[0060] The conductive contact unit 3 is used to attach to the object under test to collect electrical signals. For example, the conductive contact unit is attached to the human body to collect the human's electrocardiogram (ECG) signals.
[0061] The conductive contact unit 3 includes a conductive cloth 32 and an adhesive mesh 33. The conductive cloth is used to collect the electrical signal of the object under test.
[0062] According to some embodiments, the conductive cloth is a fiber structure provided with a conductive material, including at least one selected from gold, silver, silver chloride, titanium, and graphene. The conductive material can be plated onto the surface of the fiber structure; for example, silver can be plated onto the surface of the conductive cloth, enabling the conductive cloth to collect and conduct electrical signals.
[0063] For example, conductive cloth is made of 30-50D warp-knitted or weft-knitted fabric with a weight of 90-120g / ㎡. The material is silver, with an antibacterial rate of >99% and a surface resistance of <1Ω / cm. In this case, the conductive cloth has good conductivity and the material of the conductive cloth has been treated with anti-oxidation to resist sweat corrosion.
[0064] A first groove is provided on the conductive cloth 32, which fits into the object to be tested. The first groove is used to store hydrogel 31, so that when the electrode sheet is used, the moisture of the hydrogel 31 permeates into the conductive cloth 32, keeping the conductive cloth 32 and the object to be tested moist. Therefore, when using the electrode sheet, the contact resistance between the conductive cloth and the object to be tested can be reduced, so that the electrode sheet can better collect electrical signals and ensure the accuracy of the electrical signals collected by the conductive contact unit 3.
[0065] According to some embodiments, the hydrogel contains pure water or water and other skin-protective ingredients, such as vitamin C, hyaluronic acid, sodium pyrrolidone carboxylate, and / or diluted glycerin. The water content of the hydrogel is 50%-90%. This application uses this as an example only, but the specific water content and composition of the hydrogel are not limited thereto. The hydrogel provided in this application does not contain electrolytes to reduce the risk of skin allergies to the test object.
[0066] The adhesive mesh 33 is made of double-sided adhesive, with one side attached to the outside of the first groove and the other side attached to the object to be tested. This allows the electrode sheet to be bonded to the surface of the object by the adhesive mesh 33 when it is attached to the object, thus fixing the electrode sheet to the object and maintaining its stability.
[0067] According to some embodiments, the adhesive mesh 33 can take various shapes. Figures 3A-3D The shape of the adhesive mesh shown in the exemplary embodiment is, for example, a strip shape, such as... Figure 3A As shown; the glue web is dot-shaped, such as Figure 3B As shown; the glue mesh is mesh-like in shape, such as... Figure 3C As shown; the glue mesh is ring-shaped, such as Figure 3D As shown; or a combination of the above forms.
[0068] 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 attached to the object to be tested, needs to be greater than a first threshold value of the bottom area of the first groove to ensure the effectiveness of the conductive cloth 32 in collecting electrical signals. The first threshold value can be set by the user; for example, it can be 50%, meaning the area attached to the object to be tested needs to be greater than 50% of the bottom area of the first groove.
[0069] The insulating sheet 2 is used to attach the conductive contact unit 3 to isolate the conductive contact unit from the air.
[0070] The insulating sheet 2 includes an outer plastic layer 21 and an inner plastic layer 22. The outer plastic layer is bonded to the conductive cloth, meaning it is positioned on top of the conductive cloth 32 to seal the conductive cloth 32 and the hydrogel 31 stored within it, thus maintaining moisture in the conductive cloth 32 for a longer period. The inner plastic layer is positioned between the conductive cloth and the adhesive mesh, meaning it is positioned below the conductive contact unit 3 where it adheres to the object to be tested. The inner plastic layer 22 has a first hole, allowing the first groove of the conductive cloth 32 to pass through and adhere to the object to be tested.
[0071] like Figure 2 As shown, the outer plastic layer 21 is attached to the conductive cloth 32, the first groove of the conductive cloth 32 stores hydrogel 31, and the adhesive mesh 33 is attached below the first groove of the conductive cloth 32.
[0072] 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 is only using this as an example, but is not limited thereto.
[0073] According to some embodiments, the outer plastic layer 21 and the inner plastic layer 22 can be welded by ultrasonic welding to seal and fix the conductive contact unit 3.
[0074] The conductive assembly 1 includes a first part 12 and a second part 11. The conductive cloth 32 has a second hole, and the outer plastic layer 21 has a third hole, so that the second part 11 passes through the second hole and the third hole and connects with the first part, thereby fixing the conductive contact unit 3 and the insulating sheet 2, and transmitting the electrical signal collected by the conductive contact unit 3 to the host.
[0075] According to some embodiments, the second and third holes on the conductive cloth 32 and the outer plastic layer 21 can be positioned eccentrically, that is, the conductive component 1 is positioned eccentrically. Figure 1 As shown; the second and third holes on the conductive cloth 32 and the outer plastic layer 21 can also be located at the center, that is, the conductive component 1 is located at the center, such as Figure 4 As shown.
[0076] The fabric 5 is provided with an adhesive substance to adhere to the object to be tested. The fabric has a fifth hole so that the first groove of the conductive cloth 32 can be inserted through the fifth hole to adhere to the object to be tested.
[0077] According to some embodiments, the fabric 5 is adhesively bonded to the surface of the object to be tested.
[0078] According to some embodiments, when existing electrode pads are attached to the object to be tested, if the object sweats a lot, the entire side of the electrode pad in contact with the human body will be coated with adhesive, which will prevent the sweat from being discharged, causing the sweat to be stored in the electrode pad and causing discomfort to the human body.
[0079] Therefore, this application proposes to provide a first loop and a second loop on the fabric 5, such as... Figure 5 As shown in the diagram, the inner side of the first ring and the outer side of the second ring are adhesive-coated areas, meaning adhesive is applied to both sides of the first and second rings. The area between the first and second rings is a non-adhesive-coated area, meaning no adhesive is applied between them. This allows the electrode pads to draw moisture from the surface of the object being tested when they are attached to it. For example, it draws sweat from the surface of the object being tested to the surface away from it.
[0080] According to some embodiments, the fabric 5 is also provided with a sweat-wicking ring, such as Figure 5 As shown, the sweat-wicking ring is positioned between the first and second rings. The sweat-wicking ring is used to guide sweat from the surface of the object being tested to the surface away from the object being tested, thereby reducing the risk of allergic reactions when the object being tested is used with the electrode pads.
[0081] According to some embodiments, the fabric 5 is a one-way moisture-wicking fabric, which allows the electrode pad to conduct sweat from the surface of the object to be tested to the surface away from the object when it is attached to the object, thereby improving the comfort of using the electrode pad.
[0082] According to some embodiments, the material of fabric 5 includes cotton, linen, silk, and blended synthetic fibers. When the electrode sheet is used for a short period of time, conventional materials such as non-woven fabric and foam can also be used to reduce the production cost of the electrode sheet.
[0083] According to some embodiments, the electrode sheet may also include a sealing gasket 6. The sealing gasket 6 is bonded to the fabric 5, the rubber ring 4, and the rubber ring 7 to ensure a seal between the sealing gasket 6 and the rubber rings 4 and 7.
[0084] According to some embodiments, the sealing gasket 6 is made of biocompatible plastic. A sixth hole is provided on the sealing gasket 6, allowing the first groove of the conductive cloth 32 to adhere to the object under test through the sixth hole.
[0085] The adhesive rings in this application include a first adhesive ring 4 and a second adhesive ring 7, used to fix the fabric 5 and the sealing gasket 6. The first adhesive ring 4, made of double-sided adhesive, 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 adhesive ring 7, also made of double-sided adhesive, is positioned between the sealing gasket 6 and the release paper assembly 8, and adheres to the sealing gasket 6. The first adhesive ring 4 has a fourth hole, and the second adhesive ring 7 has a seventh hole, allowing the first groove of the conductive cloth 32 to pass through the fourth and seventh holes and adhere to the object to be tested.
[0086] According to some embodiments, such as Figure 6A and Figure 6B As shown, the diameter of the fifth hole in fabric 5 is greater than the diameter of the fourth hole in the first rubber ring 4, equal to the diameter of the seventh hole in the second rubber ring 7, and equal to the diameter of the sixth hole in the sealing gasket 6. Hole 2 is the fifth hole in fabric 5, hole 1 is the fourth hole in the first rubber ring 4 or the seventh hole in the second rubber ring 7, and hole 3 is the sixth hole in the sealing gasket 6. The outer diameters of the rubber ring 4, the sealing gasket 6, and the rubber ring 7 are the same and consistent with the size of the first ring in fabric 5. A small hole is provided between the first ring and the fifth hole in fabric 5, allowing part of the rubber ring 4 to pass through the fifth hole in fabric 5 and bond with the sealing gasket 6, and part to pass through the small hole in fabric 5 and bond with the sealing gasket 6, thus ensuring the reliability and sealing of the bonding between the rubber ring 4, fabric 5, and sealing gasket 6. Figure 5 As shown, the small hole in fabric 5 refers to the small hole on the inner side of the first ring.
[0087] 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 bonded together to form a sealed space.
[0088] The release paper assembly 8 is bonded to the conductive contact unit 3, the fabric 5, and the second adhesive ring 7 to form a sealed space to keep the conductive contact unit moist. The release paper assembly 8 includes release paper 81 and a sealing cap 82. Release paper 81 is adhered to the fabric 5 to protect the adhesive layer on the fabric 5. Release paper 81 can be easily removed when using the electrode sheet. The sealing cap 82 covers the conductive contact unit 3 and is adhered to the second adhesive ring 7, creating a sealed space for the electrode sheet to prevent moisture evaporation from the hydrogel 31 and protect the moisture in the conductive contact unit.
[0089] According to some embodiments, the sealing cap 82 is welded to the release paper 81. The sealing cap 82 is made of plastic PE or PET.
[0090] The electrode pad provided in this application has a simple structure. Hydrogel is added to the conductive contact unit to keep the conductive contact unit moist and reduce skin impedance during use, so as to better collect electrical signals. A mesh is used to fix the part of the conductive contact unit that contacts the object to be tested, which improves the positional stability of the electrode pad. One-way moisture-wicking fabric is used to quickly remove sweat, improve the comfort of wearing the electrode pad, and reduce the risk of allergies.
[0091] like Figure 7A The image shown is a front view of the electrode plate, i.e., the side facing away from the object being measured; as shown... Figure 7B The image shown is a view of the back of the electrode pad, i.e., the side that is in contact with the object being measured; as shown... Figure 7C The diagram shown is a schematic of the side of the object to be tested after the release paper assembly has been removed.
[0092] This application also provides an electrocardiogram (ECG) detection device for acquiring ECG signals from an object under test. Figure 8 As shown, the electrocardiogram (ECG) monitoring device includes electrode pads 100 and a main unit 300 as described above. The electrode pads are connected to the main unit, which processes the electrical signals acquired by the electrode pads 100.
