The invention aims to provide an electrocardio monitoring system which aims to solve the problem that the existing electrocardio signal transmission is unstable. The following description refers to the accompanying drawings.
Referring to fig. 1 to 3, an electrocardiograph monitoring system is provided in an embodiment of the present invention, which includes an electrocardiograph electrode patch 1 and an electrocardiograph detection device 2, wherein the electrocardiograph detection device 2 is detachably assembled with the electrocardiograph electrode patch 1. The electrocardio electrode patch 1 is used for monitoring electrocardio signals and transmitting the electrocardio signals to the electrocardio detection equipment 2. In one example, the electrocardio-electrode patch 1 comprises a first part 1a and a second part 1b which are separable, wherein the first part 1a is used for being attached to a first target position (such as a fourth intercostal and nearby position) to be detected, and the second part 1b is used for being attached to a second target position (such as a subclavian position) to be detected. It should be noted that, in some application scenarios, the second portion 1b may be used independently in combination with the electrocardiograph detection device 2, and at this time, a single electrocardiograph signal is collected. When the second part 1b is combined with the first part 1a, multi-lead electrocardiosignals can be acquired, so that different use requirements of users are met.
Referring to fig. 3 to 9, in the electrocardiographic electrode patch 1, a first portion 1a includes: a transmission member 11, a first attaching member 12, and a connection wire 13; the first attaching part 12 is used for attaching to a first target position (such as a fourth intercostal and nearby position) to be detected; the transmission part 11 is connected with the first attaching part 12 through the connecting wire 13; the transmission component 11 comprises a shield ground contact 111 and a first transmission contact 112; the first attachment member 12 includes a first flexible circuit board 120, and the first flexible circuit board 120 includes a first shielding layer 128 and a detection contact layer 123; the connecting wire 13 includes a signal transmission core 131 and a second shielding layer 132 wrapping the signal transmission core 131; the first shielding layer 128 is connected to the shielding 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.
Referring to fig. 3 and 10 to 12, the second portion 1b of the electrocardiographic electrode patch 1 includes a second attaching member 14, and the second attaching member 14 is used for attaching to a second target position to be detected; the second attaching part 14 includes a second transmission contact 141, and the transmission part 11 is configured to be detachably mounted on the second attaching part 14, so that the second transmission contact 141 and the first transmission contact 112 form a predetermined arrangement form, and the predetermined arrangement form corresponds to the electrocardiographic detection device 2; the second transmission contact 141 is detachably connected to the first transmission contact 112 for connection to the electrocardiographic examination device 2.
So configured, the electrocardiograph signal collected by the first attaching part 12 is transmitted to the first transmission contact 112 of the transmission part 11 through the signal transmission core 131, the electrocardiograph signal collected by the second attaching part 14 is transmitted to the second transmission contact 141 and then to the electrocardiograph detection device 2, and the interference signal is transmitted to the shielding grounding contact 111 of the transmission part 11 based on the first shielding layer 128 and the second shielding layer 132 and then to the electrocardiograph detection device 2 and grounded, so that the signal and the interference signal can be separately transmitted, and the electrocardiograph signal transmission stability can be effectively improved. For convenience of description, the side of the electrocardiograph electrode patch 1 that is used for attaching to the human body is referred to as the back side, and the side facing away from the human body is referred to as the front side.
In an alternative example, the detection contact layer 123 is a silver chloride layer, and the first transmission layer 124 is a silver paste layer, where the silver chloride has better conductivity and a certain sterilization effect. The silver paste layer has very good conductivity. Alternatively, the silver chloride layer is preferably circular, and 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 circular shape of the silver chloride layer for connection with the silver chloride layer; the extension portion extends beyond the coverage of the silver chloride layer.
Referring to fig. 6, optionally, the first attaching part 12 further includes a first flexible substrate layer 121, and the first flexible substrate layer 121 is disposed on the opposite side of the first flexible circuit board 120. The first flexible substrate layer 121 may be, for example, a medical non-woven fabric adhesive tape, and the adhesion force of the medical non-woven fabric adhesive tape ensures effective connection with human skin, so that the connection stability is improved, and the accuracy of the electrocardiograph signal is improved; in addition, the medical non-woven fabric structure has better air permeability, and can promote the comfort level of wearing.
Further, the area of the first flexible substrate layer 121 corresponding to the detection contact layer 123 has a hollow out, so that the detection contact layer 123 can be electrically connected to the skin through the first flexible substrate layer 121. Still further, the first attachment member 12 further includes a conductive gel 122 filled between the detection contact layer 123 and the skin to further reduce contact resistance therebetween.
Optionally, the first flexible circuit board 120 further includes a first transmission layer 124, a first film-covered windowing layer 125, a first connection layer 126, and a second film-covered windowing layer 127; the detection contact layer 123, the first transmission layer 124, the first film-covered window layer 125, the first connection layer 126, the second film-covered window layer 127, and the first shielding layer 128 are sequentially stacked; the first connection layer 126 has a first connection point 1261 and a second connection point 1262; the detection contact layer 123 is in contact connection with and electrically connected to the first transmission layer 124, the first transmission layer 124 is in contact connection with and electrically connected to the first connection contact 1261 through the first film-covered window layer 125, and the first shielding layer 128 is in contact connection with and electrically connected to the second connection contact 1262 through the second film-covered window layer 127; the signal transmission core 131 is connected to the first connection contact 1261, and the second shielding layer 132 is connected to the second connection contact 1262.
Referring to fig. 7, in an alternative example, the connection wire 13 is connected to a side of the first flexible circuit board 120 facing the detection contact layer 123 (i.e., a reverse side of the first flexible circuit board 120); the first film-coated fenestration layer 125 includes a first opening 1251 corresponding to the first connection contact 1261 and a second opening 1252 corresponding to the second connection contact 1262; the signal transmission core 131 is connected to the first connection contact 1261 through the first opening 1251, and the second shielding layer 132 is connected to the second connection contact 1262 through the second opening 1252. The connection wire 13 is connected to the opposite surface of the first flexible circuit board 120, so that the connection wire 13 and the first flexible circuit board 120 are connected by welding or the like. Since the first shielding layer 128 is actually located on the front side of the ecg electrode patch 1, it needs to penetrate across multiple layers if it is to be connected with the second shielding layer 132. This effect can be achieved by providing the first film-coated fenestration layer 125 and the second film-coated fenestration layer 127. Such that the interference signal experienced by the entire first flexible circuit board 120 is transmitted through the first shielding layer 128 to the second shielding layer 132.
Optionally, the second film-covering window layer 127 has a plurality of first conductive through holes 1271, where the first conductive through holes 1271 are preferably disposed corresponding to the second connection contacts 1262, and the first conductive through holes 1271 may communicate between the second connection contacts 1262 and the first shielding layer 128. Further, the first insulating layer 133 is disposed between the signal transmission core 131 of the connection wire 13 and the second shielding layer 132, and the second insulating layer 134 is preferably disposed outside the second shielding layer 132, so that the electrocardiograph signal transmitted by the signal transmission core 131 is shielded by the second shielding layer 132 in the connection wire 13. In combination with the shielding of the first transmission layer 124 and the first connection layer 126 by the first shielding layer 128, the interference signal can be transmitted to the shielding ground contact 111, and further to the electrocardiograph detection device 2, without interruption and independently from the electrocardiograph signal, so that the stability of electrocardiograph signal transmission can be improved.
Optionally, the outer surface of the connecting wire 13 is made of soft skin-friendly material, and the length of the connecting wire 13 has different specifications so as to meet the different attaching positions of the first attaching part 12 and the conditions of different users.
Preferably, the profile of the first shielding layer 128 covers at least the union of the detection contact layer 123, the first transmission layer 124, the first connection contact 1261 and the second connection contact 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. The extent of the profile 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 fills the entire contour of the first flexible circuit board 120. Note that, the full-thickness copper foil layer may be referred to herein as a full-thickness copper foil layer (i.e., copper foil layer without hollowed-out portions), and the porous copper foil layer may be referred to herein as a full-thickness copper foil layer (i.e., copper foil layer with hollowed-out portions).
Optionally, the first attachment member 12 further includes a first silk-screened layer 129, which is preferably disposed on the front side of the first flexible circuit board 120, i.e., overlying the first shielding layer 128. The first silk screened layer 129 can be used to identify, for example, information printed with a link point, for ease of wearing by a user against the information. While the first screen layer 129 may be used to protect the first shield layer 128.

Still further, the second attachment member 14 further includes a conductive gel 122 for filling between the silver paste layer and the skin to further reduce contact resistance therebetween. Optionally, the third flexible circuit board 142 further comprises a third silk-screened layer, which is preferably located on the front side of the third flexible circuit board 142. Reference is made to the first attachment member 12 for part of the construction of the second attachment member 14 and the description thereof will not be repeated here.
Alternatively, the first and second transmission contacts 112, 141 are preferably male buttons. With reference to fig. 13, the electrocardiographic detection device 2 has a female buckle 22.
