Abstract
Description
Technical Field
[0001] This utility model relates to the field of wearable medical monitoring devices, and in particular to an independent electrocardiogram electrode and a wearable device. Background Technology
[0002] Currently, screening for heart diseases primarily involves electrocardiography (ECG) and photoplethysmography (PPG), typically performed in hospitals using ECG machines. While ECG, as a non-invasive diagnostic tool, is crucial for heart disease diagnosis, a single routine ECG may not detect arrhythmias or myocardial ischemia. Holter monitoring, on the other hand, continuously monitors cardiac electrical activity throughout the entire process, recording data under various conditions including rest, activity, meals, work, study, and sleep. This allows for early warning of sudden cardiac events in various settings, such as at home or outdoors.
[0003] However, Holter monitoring cannot achieve long-term ECG monitoring such as weekly or monthly monitoring, and Holter monitoring is usually accompanied by wet electrodes. Wearing wet electrodes for a long time can easily cause patients to experience discomfort symptoms such as allergies.
[0004] With the development of smart 3C electronics and the emergence of the concept of wearable monitoring, many wearable devices capable of long-term real-time monitoring of patients' electrocardiograms (ECGs) have appeared on the market. ECG vests are one such type of wearable device. Current ECG vests typically have ECG electrodes mounted on the clothing, which collect ECG signals and record them into a recording device. This type of vest requires frequent washing, which significantly reduces the lifespan of the electrodes. In addition, there are now some independent electrodes that can be detachably connected to devices such as ECG vests and heart rate patches, solving the aforementioned problems. However, the structural design of independent electrodes is not simple enough, and patients often experience some degree of discomfort from a foreign object when wearing them. Utility Model Content

[0013] The bottom rivet fixes the plastic gasket, the flexible gasket, the second part of the electrode sheet and the rivet in sequence through riveting at the through hole.
[0014] Further, the flexible gasket is a first cloth film assembly composed of hot melt adhesive film and cloth.
[0015] Further, the independent ECG electrode further comprises:
[0016] The foam is arranged between the support assembly and the first part of the electrode sheet by adhesion.
[0017] The foam is arranged to press the front surface of the first part of the electrode sheet through the support assembly, so that the front surface of the first part of the electrode sheet is convex when the independent ECG electrode is assembled.
[0018] The foam is also provided with a slot hole at the position corresponding to the slot hole of the support assembly, and the second part of the electrode sheet is bent and passes through the foam, the support assembly in sequence through the slot hole and is fixed to the support assembly by the public rivet.
[0019] On the other hand, the independent ECG electrode can further comprise:
[0020] The second cloth film assembly is connected to the back surface of the first part of the electrode sheet by adhesion.
[0021] The second cloth film assembly is also provided with a slot hole at the position corresponding to the slot hole of the support assembly, and the second part of the electrode sheet is bent and passes through the second cloth film assembly, the support assembly in sequence through the slot hole and is fixed to the support assembly by the public rivet.
[0022] Further, the support assembly and the electrode sheet can be provided with the second cloth film assembly and the foam at the same time, and the second cloth film assembly can be arranged between the foam and the first part of the electrode sheet by adhesion.
[0023] The second cloth film assembly is also provided with a slot hole at a slot hole position corresponding to the support assembly, and the second part of the electrode sheet is bent to pass through the second cloth film assembly, the foam and the support assembly in sequence through the slot hole and is fixed to the support assembly through the male rivet buckle.
[0024] Further, the first part of the electrode sheet is at least partially missing when the second part of the electrode sheet is bent.
[0025] The shape of the second cloth film assembly is arranged to compensate for the missing part of the front surface of the first part of the electrode sheet when assembled, so that the support assembly and the foam cannot be exposed on the surface of the independent electrocardio electrode.
[0026] On the other hand, a wearable device is provided, which comprises a female buckle, an electrocardio recording host and an electrode line.

[0029] Further, the wearable device is an electrocardio clothing and a heart rate belt.
[0030] The beneficial effects of the present application are as follows:
[0031] The human electrocardio signals are collected by cooperating with the electrocardio clothing and other wearable devices, and the buckle mode achieves the purpose of being detachable, so that the electrode is not damaged by repeated washing of the wearable device, and the service life of the electrode is reduced. Further, the collection path of the independent electrocardio electrode is optimized, compared with the existing technology in which the independent electrode needs to be provided with a conductive device to punch through the collection path, the electrode sheet is arranged to be partially bendable in the present application, the second part of the electrode sheet after being bent penetrates the support assembly and is fixed to the support assembly through the male rivet buckle, so as to punch through the collection path of the electrode, the electrode structure is simple and the cost can be reduced. Further, unlike the buckle type independent electrode in the prior art, the male rivet buckle of the present application does not directly contact the part of the electrode sheet used for signal collection in the structural design, and the user wears the electrode to contact the body surface, which is more comfortable.

[0041] Example
[0042] Currently, screening for heart diseases primarily involves electrocardiography (ECG) and photoplethysmography (PPG), typically performed in hospitals using ECG machines. While ECG, as a non-invasive diagnostic tool, is crucial for heart disease diagnosis, a single routine ECG may not detect arrhythmias or myocardial ischemia. Holter monitoring, on the other hand, continuously monitors cardiac electrical activity throughout the entire process, recording data under various conditions including rest, activity, meals, work, study, and sleep. This allows for early warning of sudden cardiac events in various settings, such as at home or outdoors.
[0043] However, Holter monitoring cannot achieve long-term ECG monitoring such as weekly or monthly monitoring, and Holter monitoring is usually accompanied by wet electrodes. Wearing wet electrodes for a long time can easily cause patients to experience discomfort symptoms such as allergies.
[0044] With the development of smart 3C electronics and the emergence of the concept of wearable monitoring, many wearable devices capable of long-term real-time monitoring of patients' electrocardiograms (ECGs) have appeared on the market. ECG vests are one such type of wearable device. Current ECG vests typically have ECG electrodes mounted on the clothing, which collect ECG signals and record them into a recording device. This type of vest requires frequent washing, which significantly reduces the lifespan of the electrodes. In addition, there are now some independent electrodes that can be detachably connected to devices such as ECG vests and heart rate patches, solving the aforementioned problems. However, the structural design of independent electrodes is not simple enough, and patients often experience some degree of discomfort from a foreign object when wearing them.
[0045] Based on this, this embodiment provides an independent ECG electrode, such as... Figure 1 As shown in the embodiments of this application, the independent ECG electrode may include an electrode pad 1, a support assembly, and a male rivet.
[0046] The electrode pad 1 includes a first part and a bendable second part. When the electrode pad is working, the front of the first part contacts and adheres to the human body surface to collect surface electrocardiogram signals. The area of the second part is usually smaller than that of the first part, and the second part can be elongated. The support component is provided for shaping the independent electrode. The support component is fixed to the back of the first part of the electrode pad 1 by adhesive bonding. Furthermore, the support component is provided with a slotted hole through which the second part of the electrode pad 1 can pass. The position of the slotted hole is set so that the second part of the electrode pad 1 can pass through vertically after bending.
[0047] The second part of electrode 1 is bent and passes through a slotted hole into the support assembly, and is fixed to the support assembly by a male rivet. The bottom surface of the male rivet directly contacts the front surface of the second part of electrode 1, and the male rivet engages with a female rivet on the wearable device. This forms a data acquisition path from the body surface—the first part of electrode 1—the second part of electrode 1—the rivet—the wearable device, thus completing the acquisition of ECG signals. Compared to existing ECG electrodes, this setup simplifies the structure, eliminating the need for separate conductive elements or a conductive layer on the side in contact with the male rivet. Only a single electrode and rivet are needed to establish the acquisition path. Furthermore, the male rivet does not directly contact the first part of electrode 1, preventing users from touching it during wear and avoiding allergic reactions, while also providing greater comfort.
[0048] Preferably, the male rivet includes a base pin 4 and a fastener 7. The support assembly can be composed of a plastic gasket 5 and a flexible gasket. Both the plastic gasket 5 and the flexible gasket have through holes at their centers. Correspondingly, when the second part of the electrode sheet 1 is bent and attached to the flexible gasket, a through hole is also provided at the center of the flexible gasket to facilitate subsequent riveting processes. When assembling the independent ECG electrode of this embodiment, when the second part of the electrode sheet 1 is bent and attached to the flexible gasket, the through holes of the plastic gasket 5, the flexible gasket, and the second part of the electrode sheet 1 are positioned relative to each other. The base pin 4 is then used to fix the plastic gasket 5, the flexible gasket, the second part of the electrode sheet 1, and the fastener 7 sequentially at the through holes by riveting. After assembly, the base of the fastener 7 can directly contact the second part of the electrode sheet 1.
[0049] The plastic pad 5 prevents the independent ECG electrode from bending during use. The flexible pad is attached to the plastic pad 5 and usually serves as the outer shell of the independent ECG electrode. Therefore, those skilled in the art should note that the area of the flexible pad is generally larger than the area of the plastic pad 5, and the area of the flexible pad can be greater than or equal to the area of the first part of the electrode sheet 1. The edge of the flexible pad is fixed to the edge of the first part of the electrode sheet 1 by adhesive bonding.
[0050] Preferably, the material of the flexible gasket is not limited. In this embodiment, the flexible gasket is a first fabric assembly 6 composed of hot melt adhesive film and fabric.
[0051] As an optional embodiment, the independent ECG electrode in this embodiment further includes foam 3. Foam 3 is bonded between the support assembly and the first part of the electrode sheet 1. The foam increases the softness of the electrode sheet 1's fit. Furthermore, the foam 3 can be configured to be pressed towards the front of the first part of the electrode sheet 1 by the support assembly, so that the front of the first part of the electrode sheet convexes when the independent ECG electrode is assembled. This configuration allows the independent ECG electrode to fit more closely to the body surface when collecting ECG signals.
[0052] A slotted hole is also provided on the foam 3 at the position of the slotted hole corresponding to the support component. After the second part of the electrode sheet 1 is bent, it passes through the slotted hole and passes through the foam 3 and the support component in sequence, and is fixed to the support component by the male rivet.
[0053] As one of the optional embodiments, the independent ECG electrode of this embodiment further includes a second membrane assembly 2, which is connected to the back side of the first part of the electrode sheet 1 by an adhesive method.
[0054] The second fabric assembly 2 also has a slotted hole at the corresponding slotted hole position of the support assembly. After the second part of the electrode sheet 1 is bent, it passes through the slotted hole in sequence through the second fabric assembly 2 and the support assembly, and is fixed to the support assembly by a male rivet.
[0055] In this embodiment, foam 3 is not provided, but a second cloth film assembly 2 is provided between the support assembly and the first part of the electrode sheet 1. The second cloth film assembly 2 separates the plastic pad 5 in the support assembly from the electrode sheet 1, which can also increase the softness of the electrode sheet 1, but cannot make the first part of the electrode sheet 1 protrude.
[0056] In the two optional embodiments described above, separately setting the second fabric membrane assembly 2 between the support assembly and the first part of the electrode sheet 1 cannot make the first part of the electrode sheet 1 protrude, thus failing to achieve the technical effect of increasing the electrode's contact with the surface. While separately setting the foam 3 between the support assembly and the first part of the electrode sheet 1 can make the electrode sheet 1 protrude during the pressing process, the surface of the electrode sheet is also affected by the foam, potentially impacting the user's wearing comfort. Therefore, in a preferred embodiment, the second fabric membrane assembly 2 is set between the foam 3 and the first part of the electrode sheet 1 by adhesive bonding. The second fabric membrane assembly 2 and the foam 3 also have slotted holes at the corresponding slotted hole positions on the support assembly. After the second part of the electrode sheet 1 is bent, it passes through the slotted holes sequentially through the second fabric membrane assembly 2, the foam 3, and the support assembly, and is fixed to the support assembly by a male rivet.
[0057] This configuration allows the first part of the electrode sheet 1 to protrude while ensuring its surface is flat and smooth, making it the optimal embodiment.
[0058] Furthermore, in this embodiment, the second part of electrode 1, when not bent, is partly part of the first part of electrode 1. Therefore, when the second part of electrode 1 is bent, at least part of the front of the first part of electrode 1 will be missing. In this case, the shape of the second fabric assembly 2 can be configured to compensate for the missing portion of the front of the first part of electrode 1 during assembly, ensuring that the support assembly and foam 3 are not exposed on the surface of the independent ECG electrode. Figure 1 The electrode sheet 1 and the second film assembly 2 are shown in the figure.
[0059] To facilitate understanding by those skilled in the art, the following describes an optimal assembly method for the independent ECG electrodes described in this embodiment:
[0060] The second part of electrode 1 is bent and passed sequentially through the second membrane assembly 2, foam 3, plastic pad 5, and first membrane assembly 6, and then attached to the first membrane assembly 6. During attachment, the through holes of the plastic pad 5, the first membrane assembly 6, and the second part of electrode 1 are aligned. The bottom pin 4 is passed through the through holes, and the plastic pad 5, the first membrane assembly 6, the second part of electrode 1, and the fastener 7 are fixed by riveting. The first part of electrode 1, the second membrane assembly 2, and the first membrane assembly 6 are then bonded together. Bonding is typically done only at the edges, resulting in the first part of electrode 1 protruding towards the front. The assembled independent ECG electrode is shown below. Figure 2 As shown.
[0061] To further demonstrate the advantages of the independent ECG electrodes in this embodiment, the signal effectiveness comparison test results between this application and existing technologies are presented, such as... Figure 3 As shown:
[0062] Figure 3 This image shows a comparison of the signal effectiveness of the independent ECG electrode and the integrated ECG electrode described in this application. The experiment collected ECG signals from six users between 7 and 24 hours. The integrated ECG electrode refers to an ECG electrode integrated into a wearable device that is non-removable and cannot be used independently. Reference can be made to the ECG electrode integrated into an ECG garment as disclosed in invention patent application CN202111576965.1. Figure 3 The results show that the signal efficiency of the independent ECG electrode in this embodiment is generally better than that of the integrated ECG electrode.
[0063] In summary, the independent ECG electrode provided in this embodiment teaches a new electrode structure that is simpler in structure, more comfortable for the user when wearing the electrode in contact with the body surface, and significantly improves the effect of ECG signal acquisition compared with the prior art. It should be noted that the independent ECG electrode in this embodiment is a reusable independent ECG electrode, unlike the disposable independent ECG electrodes in the prior art. That is, when the independent ECG electrode in this embodiment is used in conjunction with ECG clothing or heart rate belts, if the ECG clothing or heart rate belts need to be washed, the independent ECG electrode can be removed, and after the ECG clothing or heart rate belts are washed, the independent ECG electrode can be reassembled to them, thus achieving reuse.
[0064] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
