Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an electrocardiogram monitoring system. Background Technology

[0002] An electrocardiogram (ECG) recorder is a device commonly used to collect human vital signs signals, specifically electrocardiogram (ECG) signals. In existing technology, ECG recorders often employ a separate design, meaning the electrode pads and the main unit are structurally separate, connected by a connecting component. Poor signal transmission stability between the electrode pads and the main unit is an unavoidable problem in this separate design, often leading to inaccurate signal transmission. While some current ECG recorders use software algorithms for filtering to stabilize the ECG signal and improve accuracy, this does not fundamentally address the source of signal instability.

[0048] To make the objectives, advantages, and features of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and are not drawn to scale, and are only used to facilitate and clarify the explanation of the objectives of the embodiments of this utility model. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different drawings may emphasize different aspects and sometimes use different scales.

[0049] As used in this invention, the singular forms “a,” “an,” “one,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the term “at least two” is generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature; “one end” and “the other end,” and “proximal end” and “distal end” generally refer to two corresponding parts, which include not only endpoints. Furthermore, the terms "installed," "connected," and "attached," as used in this utility model, and the term "set" on one element from another, should be interpreted broadly. They generally only indicate a connection, coupling, cooperation, or transmission relationship between the two elements, which can be direct or indirect through an intermediate element. They should not be construed as indicating or implying a spatial positional relationship between the two elements, meaning one element can be located inside, outside, above, below, or to one side of the other element, unless otherwise explicitly stated. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances. Additionally, directional terms such as above, below, up, down, upward, downward, left, and right are used relative to exemplary embodiments as shown in the figures, with upward or up direction pointing towards the top of the corresponding figure, and downward or down direction pointing towards the bottom of the corresponding figure.

[0050] The purpose of this invention is to provide an electrocardiogram (ECG) monitoring system to solve the problem of unstable ECG signal transmission in existing systems. The following description refers to the accompanying drawings.

[0051] Please refer to Figures 1 to 3 This utility model provides an electrocardiogram (ECG) monitoring system, comprising an ECG electrode patch 1 and an ECG detection device 2, the ECG detection device 2 being detachably assembled with the ECG electrode patch 1. The ECG electrode patch 1 is used to monitor ECG signals and transmit them to the ECG detection device 2. In one example, the ECG electrode patch 1 includes a separable first part 1a and a second part 1b, wherein the first part 1a is used to attach to a first target location to be detected (such as the fourth intercostal space and nearby), and the second part 1b is used to attach to a second target location to be detected (such as below the clavicle). It should be noted that in some application scenarios, the second part 1b can be used independently in combination with the ECG detection device 2, in which case a single-lead ECG signal is collected. When the second part 1b is used in conjunction with the first part 1a, multi-lead ECG signals can be collected to meet different user needs.

[0052] Please refer to Figures 3 to 9 In the ECG electrode patch 1, the first part 1a includes: a transmission component 11, a first attachment component 12, and a connecting line 13; the first attachment component 12 is used to attach to a first target location to be detected (such as the fourth intercostal space and nearby); the transmission component 11 is connected to the first attachment component 12 through the connecting line 13; the transmission component 11 includes a shielded ground contact 111 and a first transmission contact 112; the first attachment component 12 includes a first flexible circuit board 120, the first flexible circuit board 120 includes a first shielding layer 128 and a detection contact layer 123; the connecting line 13 includes a signal transmission core 131 and a second shielding layer 132 wrapped around the signal transmission core 131; the first shielding layer 128 is connected to the shielded ground contact 111 through the second shielding layer 132, and the detection contact layer 123 is connected to the first transmission contact 112 through the signal transmission core 131.

[0053] Please refer to Figure 3 , Figures 10 to 12 The second part 1b of the ECG electrode patch 1 includes a second attachment component 14, which is used to attach to a second target position to be detected. The second attachment component 14 includes a second transmission contact 141, and the transmission component 11 is used to be detachably assembled to the second attachment component 14, so that the second transmission contact 141 and the first transmission contact 112 form a predetermined arrangement, which corresponds to the ECG detection device 2. The second transmission contact 141 and the first transmission contact 112 are used to be detachably connected to the ECG detection device 2.

[0054] With this configuration, the ECG signal collected by the first attachment component 12 is transmitted to the first transmission contact 112 of the transmission component 11 via the signal transmission core 131, and the ECG signal collected by the second attachment component 14 is transmitted to the second transmission contact 141, and then to the ECG detection device 2. Meanwhile, interference signals are transmitted via the first shielding layer 128 and the second shielding layer 132 to the shielding ground contact 111 of the transmission component 11, and then to the ECG detection device 2 and grounded. This allows the signal and interference signals to be transmitted separately, effectively improving the stability of ECG signal transmission. For ease of description, in this embodiment, the side of the ECG electrode patch 1 that is attached to the human body is referred to as the reverse side, and the side facing away from the human body is referred to as the front side.

[0055] In an alternative example, the detection contact layer 123 is a silver chloride layer, and the first transport layer 124 is a silver paste layer. Silver chloride has good conductivity and a certain bactericidal effect. The silver paste layer has very good conductivity. Optionally, the silver chloride layer is preferably circular, while the silver paste layer includes a circular contact portion and a linear extension portion. The diameter of the contact portion may be slightly smaller than the circle of the silver chloride layer for connection with the silver chloride layer; the extension portion extends beyond the coverage area of ​​the silver chloride layer.

[0056] Please refer to Figure 6 Optionally, the first attaching component 12 further includes a first flexible substrate layer 121, which is disposed on the reverse side of the first flexible circuit board 120. The first flexible substrate layer 121 can be, for example, medical non-woven tape. The adhesive strength of the medical non-woven tape ensures effective connection with human skin, improves connection stability, and thus improves the accuracy of electrocardiogram signals. Furthermore, the medical non-woven structure has good breathability, which can improve wearing comfort.

[0057] Furthermore, the first flexible substrate layer 121 has a perforation in the area corresponding to the detection contact layer 123, so that the detection contact layer 123 can pass through the first flexible substrate layer 121 to achieve electrical conductivity with the skin. Even further, the first attachment member 12 also includes a conductive gel 122, which is used to fill the space between the detection contact layer 123 and the skin to further reduce the contact resistance between them.

[0058] Optionally, the first flexible circuit board 120 further includes a first transmission layer 124, a first film-coated window layer 125, a first connection layer 126, and a second film-coated window layer 127; the detection contact layer 123, the first transmission layer 124, the first film-coated window layer 125, the first connection layer 126, the second film-coated window layer 127, and the first shielding layer 128 are stacked sequentially; the first connection layer 126 has a first connecting contact point 1261 and a second connecting contact point 1262; the detection contact layer 123 is in contact with and electrically connected to the first transmission layer 124, the first transmission layer 124 is in contact with and electrically connected to the first connecting contact point 1261 through the first film-coated window layer 125, and the first shielding layer 128 is in contact with and electrically connected to the second connecting contact point 1262 through the second film-coated window layer 127; the signal transmission core 131 is connected to the first connecting contact point 1261, and the second shielding layer 132 is connected to the second connecting contact point 1262.

[0059] Please refer to Figure 7In an alternative example, the connecting wire 13 is connected to the side of the first flexible circuit board 120 facing the detection contact layer 123 (i.e., the reverse side of the first flexible circuit board 120); the first film-coated window layer 125 includes a first opening 1251 corresponding to the first connecting contact point 1261 and a second opening 1252 corresponding to the second connecting contact point 1262; the signal transmission core 131 is connected to the first connecting contact point 1261 through the first opening 1251, and the second shielding layer 132 is connected to the second connecting contact point 1262 through the second opening 1252. Connecting the connecting wire 13 to the reverse side of the first flexible circuit board 120 facilitates connection between the connecting wire 13 and the first flexible circuit board 120 by means of soldering or other methods. Since the first shielding layer 128 is actually located on the front side of the ECG electrode patch 1, it would need to penetrate multiple layers to connect with the second shielding layer 132. This effect can be achieved by providing the first film-coated window layer 125 and the second film-coated window layer 127. In this way, the interference signal received by the entire first flexible circuit board 120 can be transmitted to the second shielding layer 132 through the first shielding layer 128.

[0060] Optionally, the second coated window layer 127 has a plurality of first conductive vias 1271, the positions of which preferably correspond to the second connecting contact point 1262. The first conductive vias 1271 can connect the second connecting contact point 1262 and the first shielding layer 128. Further, a first insulating layer 133 is provided between the signal transmission core 131 of the connecting line 13 and the second shielding layer 132, and a second insulating layer 134 is preferably provided outside the second shielding layer 132. With this configuration, the ECG signal transmitted by the signal transmission core 131 in the connecting line 13 is effectively shielded by the second shielding layer 132. Combined with the shielding of the first transmission layer 124 and the first connecting layer 126 by the first shielding layer 128, interference signals can be transmitted uninterruptedly and independently of the ECG signal to the shielded grounding contact 111, and then to the ECG detection device 2, thereby improving the stability of ECG signal transmission.

[0061] Optionally, the outer surface of the connecting wire 13 is made of a soft and skin-friendly material, and the length of the connecting wire 13 has different specifications to meet the different attachment positions of the first attachment component 12 and the different user situations.

[0062] Preferably, the outline of the first shielding layer 128 at least covers the union of the detection contact layer 123, the first transmission layer 124, the first connecting contact point 1261, and the second connecting contact point 1262. The purpose of the first shielding layer 128 is to shield the detection contact layer 123, the first transmission layer 124, and the first connection layer 126. Therefore, the outline of the first shielding layer 128 needs to cover the union of the other structural layers. Further, the first shielding layer 128 is a copper layer that fully covers the outline of the entire first flexible circuit board 120. It should be noted that "fully covered" here may refer to a fully covered copper foil layer (i.e., a copper foil layer without perforations) in some embodiments, and to a fully covered porous copper foil layer (i.e., a copper foil layer with perforations) in other embodiments.

[0063] Optionally, the first attaching component 12 further includes a first silkscreen layer 129, which is preferably disposed on the front side of the first flexible circuit board 120, i.e., covering the first shielding layer 128. The first silkscreen layer 129 can be used for identification, such as printing information on connection points, to facilitate users in referring to the information when wearing the device. At the same time, the first silkscreen layer 129 can also be used to protect the first shielding layer 128.

[0064] Optionally, the transmission component 11 includes a second flexible circuit board 113, which includes a second connection layer 114, a third coated window layer 115, a second transmission layer 116, and a fourth coated window layer 117 arranged in sequence. The second connection layer 114 has a third connecting contact point 1141 and a fourth connecting contact point 1142. The signal transmission core 131 is connected to the third connecting contact point 1141, and the second shielding layer 132 is connected to the fourth connecting contact point 1142. The third connecting contact point 1141 is connected to the first transmission contact point 112 through the third coated window layer 115 and the fourth coated window layer 117. The fourth connecting contact point 1142 is in contact with and electrically connected to the second transmission layer 116 through the third coated window layer 115. The second transmission layer 116 is connected to the shielded grounding contact 111 through the fourth coated window layer 117.

[0065] The layered structure of the second flexible circuit board 113 is slightly different from that of the first flexible circuit board 120. Since the transmission component 11 does not need to be attached to the target position to collect electrocardiogram signals, the detection contact layer 123 and the first shielding layer 128 are omitted.

[0066] Preferably, the second flexible circuit board 113 further includes a fifth coated window layer 118, which covers the side of the second connecting layer 114 away from the third coated window layer 115. The connecting line 13 is connected to the side of the second flexible circuit board 113 facing the fifth coated window layer 118 (i.e., the reverse side of the second flexible circuit board 113). The connecting line 13 is connected to the reverse side of the second flexible circuit board 113, which facilitates the connection between the connecting line 13 and the second flexible circuit board 113 by means of soldering or other methods. It is understood that the ECG monitoring device 2 is mainly assembled and connected on the front side of the transmission component 11. Therefore, the shielded grounding contact 111 and the first transmission contact 112 are preferably located on the front side of the transmission component 11. This inevitably requires the connecting line 13 to penetrate the entire second flexible circuit board 113 to achieve electrical conduction with the shielded grounding contact 111 and the first transmission contact 112. The third laminated window layer 115, the fourth laminated window layer 117, and the fifth laminated window layer 118 achieve this effect.

[0067] In an alternative example, the fifth coated window layer 118 includes a third opening 1181 corresponding to the third connecting contact point 1141 and a fourth opening 1182 corresponding to the fourth connecting contact point 1142; the signal transmission core 131 is connected to the third connecting contact point 1141 through the third opening 1181, and the second shielding layer 132 is connected to the fourth connecting contact point 1142 through the fourth opening 1182. Optionally, the third coated window layer 115 has a plurality of second conductive vias 1151, the positions of which correspond to the contour range of the third connecting contact point 1141. The second conductive vias 1151 can connect the third connecting contact point 1141 and the second transmission layer 116.

[0068] Optionally, the second flexible circuit board 113 further includes a second silkscreen layer 119, which is preferably located on the front side of the second flexible circuit board 113, i.e., covering the fourth laminated window layer 117. The second silkscreen layer 119 can be used for identification while protecting the fourth laminated window layer 117.

[0069] Optionally, the transmission component 11 further includes a foam isolation layer 110, which is disposed on the reverse side of the second flexible circuit board 113 and is used to isolate and buffer the second flexible circuit board 113 and the second attachment component 14 (see description below).

[0070] Optionally, the shielded grounding contact 111 is a magnetic conductor. For compatible options, please refer to [reference needed]. Figure 13The ECG monitoring device 2 has a suction structure 21 corresponding to the position of the shielded grounding contact 111. The suction structure 21 is used to engage with the shielded grounding contact 111 to form an electrical connection. This allows the shielded grounding contact 111 to engage with the suction structure 21 to form an electrical connection, improving connection reliability. Furthermore, the opening position and shape of the fourth film-coated window layer 117 correspond to the position and shape of the shielded grounding contact 111. Optionally, the ECG monitoring device 2 also includes a switch and a transmission interface, such as a USB interface, for ease of operation and use.

[0071] Optionally, the second attaching component 14 further includes a second flexible substrate layer 140 and a third flexible circuit board 142, wherein the second flexible substrate layer 140 is disposed on the reverse side of the third flexible circuit board 142. The second flexible substrate layer 140 may be, for example, medical nonwoven tape.

[0072] Furthermore, similar to the first flexible circuit board 120, the third flexible circuit board 142 may also include a silver paste layer in the area corresponding to the detection site, and the area of ​​the second flexible substrate layer 140 corresponding to the silver paste layer has a cutout so that the silver paste layer can pass through the second flexible substrate layer 140 to achieve electrical conductivity with the skin. Further, the second attachment member 14 also includes a conductive gel 122, which is used to fill the space between the silver paste layer and the skin to further reduce the contact resistance between them. Optionally, the third flexible circuit board 142 also includes a third silkscreen layer, which is preferably located on the front side of the third flexible circuit board 142. Partial structure of the second attachment member 14 can be referred to the first attachment member 12, and will not be repeated here.

[0073] Optionally, the first transmission contact 112 and the second transmission contact 141 are preferably male. For compatible options, please refer to [reference needed]. Figure 13 The ECG detection device 2 has a female snap fastener 22. This allows the ECG detection device 2 to be easily snapped onto the ECG electrode patch 1. Of course, in other embodiments, the first transmission contact 112 and the second transmission contact 141 may be female snap fasteners 22, while the ECG detection device 2 has a male snap fastener; this invention is not limited to this.

[0074] Please refer to Figures 1 to 3 The following is an illustrative description of how to use the electrocardiogram monitoring system provided in this embodiment:

[0075] Step S1: Connect the male connector of the first transmission contact 112 of the transmission component 11 to the female connector 22 of the ECG detection device 2;

[0076] Step S2: Connect the male buckle of the second transmission contact 141 of the second attachment component 14 to the female buckle 22 of the ECG detection device 2;
