That is, when a person's heart is abnormal, even if he goes to the hospital for examination immediately, the short static electrocardiogram of ten seconds is often unable to capture the abnormal condition, so it is necessary to monitor the heart for 24 hours or even 48 hours continuously.
Therefore, a dynamic electrocardiogram detection device has come into play, which can detect 24 or even 48 hours of electrocardiosignals.
Typical electrocardiographic devices are disclosed in patent invention No. CN94213324.2 entitled "Standard 12-lead instantaneous electrocardiograph": the standard 12-lead instantaneous dynamic electrocardiograph consists of casing, printer on the casing, playback machine with operation keyboard, display and playback circuit, and electrocardiographic recording box with recording box circuit, and the playback machine and the recording box are connected via communication port. The playback circuit is a single-chip microcomputer circuit, and the recording box circuit is a single-chip microcomputer circuit containing acquisition, amplification, analog-to-digital conversion and data storage. The playback machine inputs initialization information to the recording box through a keyboard, a patient carries the recording box with him, after a key is pressed, the abnormal electrocardiosignals of 12 leads measured by the probe are recorded in the memory, and the signals are displayed or printed by the playback machine. The circuit structure is shown in fig. 2.
However, the dynamic electrocardiograph is large in size, and is inconvenient for a patient to carry on and completely incapable of moving or bathing. Therefore, a dynamic electrocardiograph structure with small volume and convenient carrying is needed.
Therefore, the invention also discloses a patch type dynamic electrocardiogram recorder, the structure of which is greatly reduced compared with the common electrocardiogram, and the portability of which is better. As disclosed in typical invention patents such as 201811082281.4 entitled "a patch-type dynamic electrocardiograph recorder": the utility model provides a SMD developments heart electrograph recorder, includes bottom subassembly and host computer, the bottom subassembly includes that detachable installs the bottom body on the host computer, locates the first circuit board on the bottom body, first circuit board includes first circuit board body and connects the three electrode holder on first circuit board body, and a disposable electrode piece is installed to detachable on every electrode holder.

The structure of which can be seen in figure 3. In fig. 3, 102 denotes a patch-type ecg monitor, 1021 denotes a main body, and 1033 denotes an aperture on the main body.
However, the electrocardio-chest patch is characterized in that the main machine is connected with the traditional button type electrode, the distance between the electrode buttons cannot be changed correspondingly along with the movement of the chest cavity of a human body, so that the electrocardio-chest patch is attached to the human body, the skin has strong traction feeling due to the movement of the human body, and the comfort degree is greatly reduced.
Therefore, it is necessary to design an electrode sheet structure, which can adapt to the relative position change of the electrodes on the electrode sheet when the human body moves, and improve the comfort of the human body on the basis of confirming the performance of the electrode sheet.

The redox layer is isolated and protected by the insulating layer. The further technical scheme of the invention is as follows: the insulating layer is one or the combination of polyimide, polyester and polycarbonate. These materials have good flexibility while allowing the redox layer to be firmly attached to its surface. The printing of the redox layer is well known in the art and will not be described further herein.
The further technical scheme of the invention is as follows: the redox layer includes an intermediate layer and a reaction layer. Wherein the purpose of the intermediate layer is mainly to strengthen the bonding of the reactive layer and the insulating layer.
The electrocardioelectrode piece lead obtained by the scheme has certain flexibility on the basis of having the most basic electric conductivity, and can be adapted to the requirement of being attached to the surface of a human body. When a user moves, the deformation and bending processes of the muscles on the surface layer of the body occur, and the electrocardioelectrode plates are bent along with the wires, so that the electric signal transmission is not influenced, and the user does not feel uncomfortable.
The invention also discloses an electrocardioelectrode plate, which comprises a substrate layer, at least one lead wire for the electrocardioelectrode plate, input electrodes and output electrodes, wherein the lead wire for the electrocardioelectrode plate is laid on the substrate layer, the number of the input electrodes and the number of the output electrodes are the same as that of the lead wires for the electrocardioelectrode plate, each lead wire for the electrocardioelectrode plate corresponds to one input electrode and one output electrode respectively, the input electrodes are connected with one end of the lead wires for the electrocardioelectrode plate, and the output electrodes are connected with the other end of the lead wires for the electrocardioelectrode plate.
The substrate layer is directly contacted with a human body, electrocardiosignals of the human body are sensed by the input electrodes on the substrate layer and are transmitted to the output electrodes on the substrate layer through the electrocardio electrode plates by the wires, and the electrocardiosignals of the human body are sensed. As for the positions where the input electrode and the output electrode are arranged; how to connect and realize switching on etc. with input electrode, output electrode with wire for the electrocardioelectrode piece, all are not the key point of this patent protection, and have existed the scheme that can realize among the prior art, so no longer give unnecessary details in this patent.
The further technical scheme of the invention is as follows: the substrate layer is made of flexible materials and has elasticity. The substrate layer is directly contacted with a human body, and when the skin of the human body deforms, the substrate layer deforms as well.
The further technical scheme of the invention is as follows: the electrocardioelectrode plate is laid on the substrate layer in a nonlinear way by a lead. Through the nonlinear setting, the wire is ensured to deform together when the substrate layer deforms, but the transmission of the electric signal is not influenced.
The further technical scheme of the invention is as follows: the lead for the electrocardioelectrode plate comprises at least one extending part and at least one bending part, wherein the extending part is connected with the bending part. The lead wire for the electrocardiograph electrode pad is partially nonlinear, but macroscopically still has directionality, in which the extension portion is a portion of the lead wire for the electrocardiograph electrode pad extending along a straight line, and the bent portion is a portion of the lead wire for the electrocardiograph electrode pad at a corner.
The further technical scheme of the invention is as follows: the extension has at least two first nonlinear repeating units, each of which is joined end-to-end.
The further technical scheme of the invention is as follows: the bending part is provided with a second nonlinear repeating unit or at least two second nonlinear repeating units connected with each other. By the arrangement of the repeating units, the production is facilitated as much as possible. However, the extension directions of the extension part and the bending part are different, and the stress is different when the extension part and the bending part are deformed, so that the structures of the repeating units are different. The repeating unit may be in any shape, such as a square wave shape, "M" shape, wave shape, etc., as long as repeated production can be achieved.
The further technical scheme of the invention is as follows: there is no stress concentration point on the first nonlinear repeating unit and no stress concentration point on the second nonlinear repeating unit. Because the stress at different positions is different during deformation, if stress concentration points exist, breakage or poor contact is likely to occur, and signal transmission is interrupted.

The further technical scheme of the invention is as follows: the omega2Greater than ω1Said A is2Is greater than A1. Because the bending part is bent, if the angular frequency and the amplitude of the bending part are the same as those of the extending part, the stress on the circuit per unit length of the bending part may be higher than that of the extending part, so that the stress is uneven.
The further technical scheme of the invention is as follows: a is described2Less than or equal to 2 pi/omega2The numerical value of (c). 2 pi/omega2I.e. a specific value of the period of the wave function, in other words, the height of the bending part is not greater than its length per period. Therefore, the bending part can be ensured to be smooth enough, and the stress is ensured to be small.
The further technical scheme of the invention is as follows: the electrocardio-electricityThe width of the lead wire for the pole piece is not more than A1Half of that. The wider the wire width, the lower the resistivity thereof, the more favorable the signal transmission, but the larger the wire width, the worse the portability of the electrode plate, and meanwhile, when the wire width is more than a half of a certain amplitude, the deformation is difficult to realize.
The further technical scheme of the invention is as follows: each lead for the electrocardio-electrode plate is arranged in parallel, and the distance between the leads for the electrocardio-electrode plates is more than A1Half of that. The leads for each electrocardio electrode plate are too close, so that the leads may contact with each other when a human body moves, but the longer the distance is, the more the leads are not favorable for portability.

The invention provides an electrode plate device. The present invention will be described in detail below with reference to the accompanying drawings and examples.
The invention firstly discloses a lead for an electrocardio electrode plate, and refer to fig. 4.
The lead for the electrocardioelectrode plate comprises an insulating layer 125 and an oxidation-reduction layer, wherein the oxidation-reduction layer is laid on the insulating layer, the width of the longitudinal section of the oxidation-reduction layer is not more than that of the insulating layer, the thickness of the longitudinal section of the insulating layer is more than that of the oxidation-reduction layer, the insulating layer is made of a flexible non-conductor material, and the oxidation-reduction layer has conductivity. The redox layer is isolated and protected by the insulating layer.
As can be seen from fig. 4, the redox layer includes an intermediate layer 124 and a reaction layer 123. In this embodiment, the intermediate layer is an Ag layer, which can make Ag \ AgCl as a reaction layer better adhere to the insulating layer, thereby better reacting.
Wherein, the insulating layer is one or the combination of more of polyimide, polyester and polycarbonate. These materials have good flexibility while allowing the redox layer to be firmly attached to its surface. The printing of the redox layer is well known in the art and will not be described further herein.
In the embodiment, PET is selected as a base material of the insulating layer, and the PET has good flexibility and mechanical property and is low in cost.
The electrocardioelectrode piece lead obtained by the scheme has certain flexibility on the basis of having the most basic electric conductivity, and can be adapted to the requirement of being attached to the surface of a human body. When a user moves, the deformation and bending processes of the muscles on the surface layer of the body occur, and the electrocardioelectrode plates are bent along with the wires, so that the electric signal transmission is not influenced, and the user does not feel uncomfortable.
The specific embodiment also discloses an electrocardioelectrode plate, and the structure of the electrocardioelectrode plate can refer to fig. 5-7.
The electrocardio-electrode plate comprises a substrate layer 11, at least one lead 12 for the electrocardio-electrode plate laid on the substrate layer, an input electrode 14 and an output electrode 13, wherein the number of the input electrode and the output electrode is the same as that of the lead for the electrocardio-electrode plate, each lead for the electrocardio-electrode plate corresponds to one input electrode and one output electrode respectively, the input electrode is connected with one end of the lead for the electrocardio-electrode plate, and the output electrode is connected with the other end of the lead for the electrocardio-electrode plate.
The electrocardiographic monitoring can be divided into multi-lead and single-lead. The electrocardio information acquired by multi-channel acquisition is richer, and myocardial ischemia, myocardial infarction and the like can be monitored. The single guide has practical significance for screening the major cardiac diseases of arrhythmia, especially for screening atrial fibrillation.
The electrode sheet in this embodiment is a single-conductor sheet having three pairs of mutually independent electrodes thereon, and thus three conductors. It is anticipated that the number of conducting wires of a multi-conducting pole piece will be larger, but the principle is the same as that of a single conducting wire.
The substrate layer directly contacts with the human body, the electrocardiosignal of the human body is sensed by the input electrode on the substrate layer, and the electrocardiosignal is transmitted to the output electrode on the substrate layer through the electrocardio electrode plate in the patent by a lead, so that the electrocardiosignal of the human body is sensed. As for the positions where the input electrode and the output electrode are arranged; how to connect and realize switching on etc. with input electrode, output electrode with wire for the electrocardioelectrode piece, all are not the key point of this patent protection, and have existed the scheme that can realize among the prior art, so no longer give unnecessary details in this patent.
The further scheme of the specific embodiment is as follows: the substrate layer is made of flexible materials and has elasticity. The substrate layer is directly contacted with a human body, and when the skin of the human body deforms, the substrate layer deforms as well.
In this embodiment, the substrate layer is selected to be PU, but those skilled in the art will recognize that any material having certain mechanical properties and good biocompatibility, such as PCL, can be used as the raw material of the substrate layer.
In this embodiment, the lead for the electrocardiograph electrode sheet is laid on the substrate layer in a nonlinear manner, referring to fig. 6. Through the nonlinear setting, the wire is ensured to deform together when the substrate layer deforms, but the transmission of the electric signal is not influenced.
The further scheme of the specific embodiment is as follows: the lead for the electrocardioelectrode sheet comprises at least one extension part 121 and at least one bending part 122, wherein the extension part and the bending part are connected with each other. The lead wire for the electrocardiograph electrode pad is partially nonlinear, but macroscopically still has directionality, in which the extension portion is a portion of the lead wire for the electrocardiograph electrode pad extending along a straight line, and the bent portion is a portion of the lead wire for the electrocardiograph electrode pad at a corner.
The further scheme of the specific embodiment is as follows: the extension has at least two first nonlinear repeating units, each of which is joined end-to-end.
The further scheme of the specific embodiment is as follows: the bending part is provided with a second nonlinear repeating unit or at least two second nonlinear repeating units connected with each other. By the arrangement of the repeating units, the production is facilitated as much as possible. However, the extension directions of the extension part and the bending part are different, and the stress is different when the extension part and the bending part are deformed, so that the structures of the repeating units are different. The repeating unit may be in any shape, such as a square wave shape, "M" shape, wave shape, etc., as long as repeated production can be achieved.
In the present embodiment, the first repeating unit and the second repeating unit are both sine waves, but the patent does not limit that the first repeating unit and the second repeating unit are necessarily the same, and one possible way is: the first repeating unit may be a square wave and the second repeating unit a sine wave, or even the first repeating unit may comprise a variety of different waveforms, for example a combination of a sine wave and a square wave.
The further scheme of the specific embodiment is as follows: there is no stress concentration point on the first nonlinear repeating unit and no stress concentration point on the second nonlinear repeating unit. Because the stress at different positions is different during deformation, if stress concentration points exist, breakage or poor contact is likely to occur, and signal transmission is interrupted.
The further scheme of the specific embodiment is as follows: one of the sine waveform and the cosine waveform of the first nonlinear repeating unit, and the function expression of the sine waveform of the first nonlinear repeating unit is
The above-mentionedThe function expression of the cosine waveform of the first nonlinear repeating unit is
The second nonlinear repeating unit is one of sine waveform and cosine waveform, and the function expression of the sine waveform of the second nonlinear repeating unit is
The function expression of the cosine waveform of the first nonlinear repeating unit is
Wherein A is1Is the amplitude of the first non-linear repeating unit, A2Is the amplitude, ω, of said second non-linear repeating unit1Is the angular frequency, ω, of said first non-linear repeating unit2Is the second non-linear repeating unit angular frequency, x is the amount of the abscissa axis of the first non-linear repeating unit or the second non-linear repeating unit,

In general, no horizontal or vertical phase shift is required, i.e.
And b are both 0. It should be noted that the zero point of the function is set at the beginning of the wire.
The further scheme of the specific embodiment is as follows: the omega2Greater than ω1Said A is2Is greater than A1. Because the bending part is bent, if the angular frequency and the amplitude of the bending part are the same as those of the extending part, the stress applied to the circuit per unit length of the bending part may be higher than that applied to the extending part, so that the stress is not uniform.
The further scheme of the embodiment is that: a is described2Less than or equal to 2 pi/omega2The numerical value of (c). 2 pi/omega2I.e. a specific value of the period of the wave function, in other words, the height of the bending part is not greater than its length per period. Therefore, the bending part can be ensured to be smooth enough, and the stress is ensured to be small.
The further scheme of the specific embodiment is as follows: the width of the lead for the electrocardioelectrode plate is not more than A1Half of that. The wider the wire width, the lower the resistivity thereof, the more favorable the signal transmission, but the larger the wire width, the worse the portability of the electrode plate, and meanwhile, when the wire width is more than a half of a certain amplitude, the deformation is difficult to realize.
In this embodiment, each of the leads for the electrocardiographic electrode plate is disposed in parallel, and the distance between the leads for the electrocardiographic electrode plate is greater than a1Half of that. Reference may be made to fig. 7. The leads for each electrocardio electrode plate are too close, so that the leads may contact with each other when a human body moves, but the longer the distance is, the more the leads are not favorable for portability.

The electrocardio monitoring devices in this scheme includes host computer and electrocardioelectrode piece, has reduced the volume of traditional electrocardio appearance greatly, simultaneously because the electrode piece has tensile and pliability ability, can take place deformation along with the human body together, and the human body can not feel uncomfortable because of the electrode piece in the motion process, and the electrode piece can not take place deformation and transmit not smooth because of the human body yet.
The further scheme of the specific embodiment is as follows: the induction electrode has magnetism. Through setting up magnetism for induction electrode is better and output electrode location and be connected.
The invention has the beneficial effects that: the electrocardioelectrode piece is with wire itself that this scheme provided has certain bending performance and tensile properties, and the demand that the wire takes place deformation when can adapt to human motion. Furthermore, the arrangement of the nonlinear repeating units in the electrocardioelectrode plate provided by the scheme further provides a space for the stretching of the lead, and finally the electrocardioelectrode plate monitoring device adopting the electrocardioelectrode plate can be in good contact with a human body, so that the human body does not feel uncomfortable due to the electrode plate in the motion process, and the electrode plate is not unsmooth in transmission due to the deformation of the human body.
