Description

Technical Field

[0001] The utility model relates to the field of electrocardiogram monitoring, in particular to an electrocardiogram electrode sheet and an electrocardiogram recorder. Background Art

[0002] Electrocardiogram (ECG) is one of the most commonly used means for heart detection. Currently, the detection of ECG signals in hospitals is usually done by connecting a 12-lead ECG machine with wet electrodes worn on a fixed ECG signal collection position on the human body. Since the application scenario of ECG machines in hospitals is too single, they can only be used to check patients who come to the hospital, and cannot meet the needs of patients for ECG monitoring at home. Now, many wearable ECG recorders have emerged on the market. They are small in size, easy to wear, and can be worn on the body surface to achieve real-time ECG monitoring at home. The design concept of wearable ECG recorders is to wear them without feeling, and the number of electrodes is generally limited. Due to limitations, most of them can achieve single-lead or three-lead ECG monitoring. This type of ECG recorder also needs to be used with electrodes. Most of the electrodes on the market are single electrodes. When worn, the ECG electrodes need to be pasted on different parts of the body surface to collect signals. Users need to stick multiple electrodes on their bodies, which is cumbersome and the pasting positions cannot always be accurate. In addition, user compliance of such products is not high during use. Some users do not remove the electrodes in accordance with the standard method, which may cause the electrode wires of the ECG recorder to be torn, thereby reducing the service life of the ECG recorder. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide an ECG electrode sheet and an ECG recorder, which fix multiple electrodes on the same adhesive surface and shorten the electrode spacing, making it easy for users to wear and have high compliance, thereby increasing the service life of the ECG recorder.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An electrocardiogram (ECG) electrode sheet comprising an adhesive member, an ECG electrode, and a PET transparent film. The ECG electrode comprises a gel layer, a silver chloride layer, and an electrode buckle, arranged sequentially from the skin-closest side to the skin-farthest side. The adhesive side of the adhesive member is in contact with the silver chloride layer, the base of the electrode buckle is fixed to the silver chloride layer, and the adhesive member is provided with a through hole for the electrode buckle to pass through the adhesive member.

[0006] The PET transparent film is attached to the adhesive side of the adhesive member and can be torn off before the ECG electrode sheet is attached to the human body surface;

[0007] The ECG electrode sheet includes at least two ECG electrodes, the spacing between the ECG electrodes is 40 mm to 45 mm, and the adhesive piece is provided with at least two through holes.

[0008] Furthermore, the ECG electrode sheet includes three ECG electrodes, and the distance between any two of the ECG electrodes is 45 mm.

[0009] Furthermore, the cross-sectional length of the adhesive piece is 132 mm, and the contour of the adhesive piece is a plurality of tangent arcs.

[0010] Furthermore, the ECG electrode sheet includes two ECG electrodes, and the distance between each two of the ECG electrodes is 45 mm.

[0011] Furthermore, the cross-sectional length of the adhesive piece is 87 mm, and the contour of the adhesive piece is a plurality of tangent arcs.

[0012] Furthermore, a conductive silicone layer is provided on the side of the ECG electrode close to the skin, and the conductive silicone layer is bonded to the gel layer.

[0013] Furthermore, the cross-sectional diameter of the conductive silicone layer is 16 mm to 30 mm, and the cross-sectional areas of the gel layer, the silver chloride layer and the electrode button base are smaller than the cross-sectional area of ​​the conductive silicone layer.

[0014] Furthermore, a reinforcing member is at least partially provided on a side of the adhesive member away from the skin, the cross section of the reinforcing member can cover the cross section of the ECG electrode, and the reinforcing member is a release film or a PET film.

[0015] Furthermore, the adhesive member is non-woven fabric.

[0016] On the other hand, an electrocardiograph recorder includes a main unit and a lead wire, wherein the lead wire and the main unit are provided with an electrode buckle female buckle, and the electrode buckle female buckle can be buckled with the above-mentioned electrode buckle male buckle.

[0017] The beneficial effects of the present invention are:

[0018] Installing multiple ECG electrodes on an electrode sheet facilitates the user's fitting operation and improves the user experience. On this basis, the distance between each electrode is shortened. Compared with the traditional single electrode, the pasting area remains unchanged while ensuring sufficient pasting stability, thereby improving the user's wearing comfort and avoiding the situation where the user has low compliance when removing the electrode and thus damages the electrode wire.

[0032] Electrocardiogram (ECG) is one of the most commonly used means for heart detection. Currently, the detection of ECG signals in hospitals is usually done by connecting a 12-lead ECG machine with wet electrodes worn on a fixed ECG signal collection position on the human body. Since the application scenario of ECG machines in hospitals is too single, they can only be used to check patients who come to the hospital, and cannot meet the needs of patients for ECG monitoring at home. Now, many wearable ECG recorders have emerged on the market. They are small and easy to wear. They can be worn on the body surface to achieve real-time ECG monitoring at home. The design concept of wearable ECG recorders is to wear them without feeling, and the number of electrodes is generally limited. Due to limitations, most of them can achieve single-lead or three-lead ECG monitoring. This type of ECG recorder also needs to be used with electrodes. Most of the electrodes on the market are single electrodes. When worn, the ECG electrodes need to be pasted on different parts of the body surface to collect signals. Users need to stick multiple electrodes on their bodies, which is cumbersome and the pasting positions cannot always be accurate. In addition, user compliance of such products is not high during use. Some users do not remove the electrodes in accordance with the standard method, which may cause the electrode wires of the ECG recorder to be torn, thereby reducing the service life of the ECG recorder.

[0033] This embodiment provides an ECG electrode sheet, on which multiple electrodes are arranged and the distance between the electrodes is effectively shortened, thereby improving the user's wearing experience and comfort while ensuring sufficient adhesive strength.

[0034] An electrocardiogram electrode sheet, such as Figure 1-4As shown, it includes an adhesive member 1, an ECG electrode 2, and a PET transparent film 4. The ECG electrode 2 includes a gel layer 21, a silver chloride layer 22, and an electrode button 23 arranged in sequence from the skin side to the skin side. The adhesive side of the adhesive member 1 is in contact with the silver chloride layer 22, and the base of the electrode button 23 is fixed to the silver chloride layer 22. The adhesive member 1 is provided with a through hole for the electrode button 23 to pass through the adhesive member 1.

[0035] The PET transparent film 4 is attached to the adhesive side of the adhesive member 1 and can be torn off before the ECG electrode sheet is attached to the human body surface;

[0036] When the patient uses the device, the PET transparent film 4 is torn off to expose the adhesive side, and the electrode is pasted on the corresponding ECG collection position on the body surface. When pasting, make sure that the adhesive piece does not have wrinkles to ensure the pasting effect. After pasting, the ECG recorder that matches the ECG electrode sheet is installed and fixed on the electrode sheet. The ECG recorder is pre-set with an electrode buckle female buckle, which is fixed by buckling the female buckle and the female buckle together.

[0037] In addition, the ECG recorder can be installed on the ECG electrode sheet first, and then the ECG electrode sheet can be attached to the corresponding ECG collection position on the body surface.

[0038] After wearing the device, the electrocardiogram recorder is started, and the electrocardiogram signal is transmitted to the electrocardiogram recorder through the body surface-gel layer 21-silver chloride layer 22-electrode buckle 23 to form a collection circuit.

[0039] Furthermore, the ECG electrode sheet includes at least two ECG electrodes 2, the spacing between the ECG electrodes 2 is 40-45 mm, and the adhesive member 1 is provided with at least two through holes. Figure 1-3As shown, in this embodiment, there are two types of ECG electrode sheets, three-electrode and two-electrode, and the spacing between the ECG electrodes is 45mm. In the current design of ECG electrode sheets, one ECG electrode sheet is generally only provided with one electrode, and in order to ensure the bonding strength, a larger bonding area is required. Therefore, the diameter of the existing ECG electrode sheet is generally more than 50mm, with 50mm and 55mm being the most common. At present, the application scenario of ECG wearable devices, such as single-lead and three-lead ECG recorders, is generally home monitoring. Home monitoring is normalized monitoring, emphasizing non-sensing wear. It is necessary to reduce the weight and volume of the ECG recorder as much as possible to improve the user's wearing experience. The lead wire of the ECG recorder also needs to be as thin as possible. The existing ECG electrode sheets with a diameter of 50mm or 55mm, when used in conjunction with this type of ECG recorder, have an overly large diameter of the ECG electrode sheets and an overly short lead wire of the ECG recorder, which results in overlapping of the electrodes when attached. This attachment method reduces the wearing experience of the patient user, and the attachment effect is not firm, and the quality of the collected ECG signal also decreases accordingly. The ECG electrode sheet of this embodiment shortens the distance between the electrodes to be suitable for the above-mentioned ECG recorder. Multiple electrodes are attached based on the same adhesive piece, and there is no overlapping of multiple electrodes when attached. When the user uses it, three electrodes are attached to the body surface signal collection position at one time, which can improve the user experience.

[0040] Furthermore, for the three-electrode ECG electrode sheet, the cross-sectional length of the adhesive member 1 is 132 mm, and the ECG electrodes 2 on both sides are 21 mm away from the edge of the adhesive member 1; for the two-electrode ECG electrode sheet, the cross-sectional length of the adhesive member 1 is 87 mm, and the ECG electrodes 2 on both sides are 21 mm away from the edge of the adhesive member 1; compared with the prior art of attaching three electrodes with diameters of 50 mm and 55 mm, the ECG electrode of this embodiment reduces the total adhesive area while ensuring the adhesive strength, thereby improving the wearing comfort of the user, and in the mass production process, shortens the distance between the ECG electrode sheets, making it easier for the mold blade to cut, thereby improving production efficiency. Furthermore, the application scenarios of ECG recorders and ECG patches are not limited to hospitals. Patient compliance when using them at home is not as high as when using an ECG machine in a hospital. In actual use, they are not always used in accordance with the standard method. For example, when using an existing single-lead ECG recorder with three ECG electrodes, some patients remove the remaining electrodes by pulling them off after removing the first electrode. This method may damage the lead wire of the ECG recorder and reduce the service life of the ECG recorder. However, the ECG electrode patch in this embodiment sets the ECG electrode 2 on the same adhesive piece, avoiding the situation of improper user use through structural design.

[0041] As one of the preferred embodiments, Figure 5As shown, the ECG electrode 2 is provided with a conductive silicone layer 24 close to the skin side. The conductive silicone layer 24 is bonded to the gel layer 21. The gel directly adheres to the human body and is prone to skin allergies when worn for a long time. In this embodiment, a conductive silicone layer 24 is added between the gel layer 21 and the skin. The conductive silicone layer is a dry material, is friendly to skin affinity, and can be worn for a long time.

[0042] Preferably, the cross-sectional diameter of the conductive silicone layer 24 can be 16mm-30mm, and the cross-sectional areas of the gel layer 21, the silver chloride layer 22 and the base of the electrode button 23 are smaller than the cross-sectional area of ​​the conductive silicone layer 24; under the premise of ensuring sufficient bonding strength, the smaller the bonding area, the more comfortable the user will wear it, so the larger the ratio of the electrode collection area to the bonding area, the more comfortable it is. After testing, when the cross-sectional diameter of the conductive silicone layer is 16mm, it will neither affect the bonding strength nor have a significant impact on the signal quality. Therefore, in this embodiment, 16mm is preferably used as the cross-sectional diameter of the conductive silicone layer to further improve the user's seamless wearing experience.

[0043] As a preferred Figure 1-Figure 5 As shown, a release film 3 is provided at least partially on the side of the adhesive member 1 away from the skin. The cross section of the release film 3 can cover the cross section of the ECG electrode 2. The release film 3 is a reinforcing member that can enhance the strength of the ECG electrode 2.

[0044] Preferably, the adhesive member 1 is made of non-woven fabric. While ensuring adhesive strength, the non-woven fabric is more breathable, and the patient-user experience of adhesive bonding is more comfortable.

[0045] On the other hand, this embodiment provides an electrocardiogram recorder, including a host and a lead wire, wherein the lead wire and the host are provided with an electrode buckle female buckle, and the electrode buckle female buckle can be buckled with the electrode buckle 23 of the above-mentioned electrocardiogram electrode sheet to realize electrocardiogram collection, such as Figure 6 The figure shows a schematic diagram of the use of an ECG recorder and ECG electrodes.

[0046] As a preference, some ECG recorders do not only have the function of collecting single or three leads, but can also collect more leads, which requires more ECG electrodes. For this application scenario, an interface can be set on the ECG recorder in this embodiment, and the ECG electrodes close to the ECG recorder and the ECG electrodes far away from the ECG recorder can be connected through lead wires to achieve the collection of more leads, such as Figure 7 As shown, a three-electrode ECG electrode sheet and a two-electrode ECG electrode sheet are connected to achieve five-lead ECG acquisition.

[0047] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
