Background

With the development of the Chinese society and the improvement of the economic level, cardiovascular and cerebrovascular diseases quickly become one of the main diseases threatening the life health of urban people. For patients with cardiovascular and cerebrovascular diseases, it is very important to detect the cardiac electric signals at any time so as to find abnormality in time and seek medical advice in time.

The conventional instant electrocardio detection equipment comprises a host machine, a lead wire and an electrode plate, wherein the electrode plate is a disposable article, and the host machine and the lead wire can be repeatedly used.

Typical conventional real-time electrocardiographic detection devices are disclosed in utility model patent No. CN200720125633.0, entitled "disposable electrode sheet type conventional electrocardiographic lead wire": a disposable electrode sheet type conventional electrocardiogram lead wire belongs to a lead wire for monitoring and describing a conventional electrocardiogram, a cable (5) is connected with a shielding glue line (3) through a fixed connection deconcentrator (4), the tail end of the shielding glue line (3) is connected with a connector (1), and a disposable adhesive electrode (2) is bonded on the working surface of the connector (1). The invention has the advantages that: the clip type and the suction ball type metal electrodes in the prior art are changed into the disposable patch type electrode plate, so that the stable contact between the electrode and the skin of the corresponding part can be effectively enhanced and ensured, the success rate of electrocardiographic examination, the tracing quality and the like are improved, meanwhile, the continuous use of the electrode is changed into the disposable use, the requirement of public health is met, and the disposable patch type electrode is simple, convenient and effective in structure and easy to implement. The structure is shown in fig. 1.

However, the normal electrocardiogram can only record the heart electrical activity within a certain short time, and the abnormal condition of the heart is often paroxysmal, transient or sporadic. 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, playback machine with 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 detected 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, a patch type dynamic electrocardiogram recorder is invented, the structure of the recorder is greatly reduced compared with that of a common electrocardiogram, and the portable performance of the recorder is better. As disclosed in a typical invention patent such as 201811082281.4 entitled "a surface mount type dynamic electrocardiogram 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. Like this with bottom body detachable install on the host computer, set up the circuit board alone on the bottom surface of bottom body, separated the circuit board on with the host computer and the circuit board on the bottom body, make circuit and disposable electrode piece separately simultaneously, every detect a patient after, only need change install on the bottom body disposable electrode piece can, and this kind of disposable electrode piece one only need a few mao qian, for among the prior art greatly reduced the cost of disposable electrode piece. The structure of which can be seen in figure 3. In fig. 3, 102 denotes a patch-type dynamic electrocardiogram recorder, 1021 denotes a main body, and 1033 denotes an aperture on the main body.

However, most of the current wearable electrocardio-type breast patches are connected by electrode buttons, that is, the electrode plates are connected with the lead by a structure similar to a button, so that the acquisition equipment is quite bloated due to the existence of various circuits, and although some schemes further directly connect the electrodes with a host, the adhesive position selectivity of the electrode plates is greatly limited due to the absence of the lead.

In addition, the connection mode of the electrode buckle structure is relatively rigid, when a wearer moves, the skin at the viscose part of the wearer is relatively displaced, and the electrode is easy to fall off, so that popularization of medical products for potential patients is greatly hindered.

Therefore, there is a need to design an electrode plate structure, which has a light structure, does not need an external connecting wire, and has a certain mechanical property between the wire and the electrode, so that the daily working life is not affected when a patient wears the electrode plate structure, and the comfort of the human body is improved on the basis of confirming the performance of the electrode plate.

Meanwhile, it should be noted that the material of the substrate layer needs to be selected from PU, PCL or similar biocompatible materials with certain mechanical flexibility.

The electrode structure in the market is mainly in a strip shape, and is usually fixedly connected or detachably connected by a plurality of parts, and a structure for integrally forming an electrode and a lead is not provided.

In the present embodiment, since the electrocardiograph is a single-conduction electrocardiograph, only 3 pairs of electrodes are designed, but it is anticipated that one skilled in the art can increase the number of pairs of electrodes as needed. In addition, in the present embodiment, although the input electrode and the output electrode are provided in a circular shape, the shape of the input electrode and the output electrode is not limited to a circular shape in practice, and may be other shapes such as a square shape, a semicircular shape, or the like.

It can be seen that the electrode is directly connected with the lead, two sharp corners exist at the connecting position, namely stress concentration points, and when the lead and the electrode are displaced relatively, the pressure bearing of the two points is larger than that of other points, so that the lead or the electrode is broken.

In thespecific embodiment 2 of the scheme, the electrocardio-electrode has no stress concentration point, and the structure is shown in fig. 5.

As shown in fig. 6 and 7, the input electrode includes an input electrode portion and a first transition portion, the output electrode includes anoutput electrode portion 1211 and asecond transition portion 1222, the first transition portion is of a gradual change structure, and a portion connected with the lead is narrow in longitudinal section and a portion connected with the input electrode portion is wide in longitudinal section; the second transition part is of a gradual change structure, and the longitudinal section of the part connected with the lead is narrow, and the longitudinal section of the part connected with the output electrode part is wide.

The two transition parts are too short to achieve a good transition effect, and too long easily affects the tensile property of the wire. And therefore, its length needs to be limited.

The invention also discloses a method for manufacturing the electrocardio-electrode, which comprises the following steps as shown in fig. 9:

step 1: printing the redox layer on the insulating layer to obtain a conductive film; the redox layer completely covers the insulating layer, wherein the insulating layer is made of flexible non-conductor materials, the redox layer has electric conduction capability, and the volume of the insulating layer is larger than that of the electrocardio-electrode;

step 2: and cutting the conducting film by a cutting die to obtain the electrocardio-electrode.

Different from the prior method of respectively manufacturing, reprocessing and connecting the electrodes together, the method obtains the electrodes very conveniently through a printing process and a knife film process.

As shown in fig. 10 and 11, the invention also discloses an electrocardiograph electrode, which comprises a substrate layer 13, a host layer 16 and a first outer layer 11, wherein the substrate layer and the cover layer wrap the electrocardiograph electrode layer by layer, and the input electrode and the output electrode of the electrocardiograph electrode face opposite directions; the laminating layer is provided with output through holes 161 with the same number as the output electrodes, and the positions of the output through holes correspond to the positions of the output electrodes; the substrate layer is provided with input through holes 131 the same as the input electrodes in number, the positions of the input through holes correspond to the positions of the input electrodes, conductive gel 14 is arranged in the input through holes in an interference mode, and the conductive gel is connected with the input electrodes; the output through hole is provided with conductive particles 15 in an interference manner, and the conductive particles are connected with the output electrode; the distance between the projection position of the input electrode and the projection position of the output electrode is more than 12 mm; the film coating layer, the substrate layer and the electrode circuit are flexible; the projection area of the input through hole is larger than that of the input electrode; the projection area of the output through hole is larger than that of the output electrode.

Wherein the substrate layer directly contacts with human skin, and the bioelectricity signal of human body is received to the input electrode on the substrate layer, transmits the signal of telecommunication to output electrode through the wire, and output electrode links to each other and transmits the signal of telecommunication for the host computer with the equipment host computer, realizes human electrocardiosignal's response. The structure concentrates the input electrode, the output electrode and the lead in a lamellar structure, greatly simplifies the prior electrode slice, ensures that the electrode slice can be very thin and can be correspondingly deformed according to the movement of people. Meanwhile, it should be noted that the material of the substrate layer needs to be selected from PU, PCL or similar biocompatible materials with certain mechanical flexibility.

How to connect and realize leading etc. with input electrode, output electrode with wire for electrocardioelectrode piece is not the key point of this patent protection, and has existed the scheme that can realize among the prior art, so no longer give consideration to in this patent.

The conductive gel can be hydrogel or other semisolid gel. The conductive gel may be KCL or other chloride salt. Through the full-overflow filling, the conductive gel is better contacted with the skin and the input electrode, and the electric signal is received.

The conductive gel is of a track-type structure, and the projection of the conductive gel on the substrate layer is larger than that of the input electrode.

As can be seen from the figure, the conductive gel is arranged into a runway-type structure, so that the volume increase can be realized to the greatest extent on the basis of ensuring the distances between the gel and the edge of the electrode plate and other electrodes.

In order to prevent poor contact between the output electrode and the host, conductive particles are additionally added to ensure the smooth connection between the output electrode and the host. The conductive particles can be any material having conductive properties, such as metal blocks, multi-layered metal cloths, conductive glues, and the like.

In this embodiment, theconductive particles 15 include an expansion body and at least one layer of metal cloth, and the metal cloth is wrapped around the expansion body.

In this embodiment, the expansion body has elasticity.

By setting the expansion body to be elastic, the interference configuration of the conductive particles can be realized, and the combination of the output electrode and the host machine is ensured. The metal cloth is convenient for realizing the conductive performance.

In this embodiment, as shown in fig. 10, the electrocardiograph electrode has a bend, and the circuit directions at both ends of the bend are opposite. Because the direction of the input electrode is opposite to that of the output electrode, the direction of the lead is changed by arranging a structure, and one possible mode is that the lead is bent (namely, the lead structure rotates), and the electrodes can be made to be conductive up and down and can be selected according to the needs.

In this embodiment, as shown in fig. 10, the bend is provided on the output electrode. The output electrode can be made into a two-sided structure, the middle of the output electrode is bent, and the two ends of the output electrode are bonded, so that the upper and lower parts of the output electrode can conduct electricity.

The addition of the second adhesive layer can ensure the stability of the position of the output electrode.

In this embodiment, as shown in fig. 10, afirst release film 17 is detachably disposed on the host layer, and a projection of the first release film on the host layer completely covers the host layer. Because the host computer layer can be equipped with glue (first viscose layer), consequently for the convenience of use, can add a rete on first viscose layer, tear this layer of structure earlier when using.

In this embodiment, as shown in fig. 10, a third adhesive layer is disposed below the substrate layer, asecond release film 18 is detachably disposed below the third adhesive layer, and a projection of the second release film on the substrate layer completely covers the substrate layer. The substrate layer is direct to link to each other with the human body, in order to increase its firm nature of being connected with the human body, can increase the third viscose layer, simultaneously for convenient attached, when not using, paste the third viscose layer from the type membrane through the second.

In this embodiment, as shown in fig. 10, the electrocardiograph electrode sheet is further detachably provided with athird release film 19, the third release film is of a hollow structure, and the inner side of the third release film partially overlaps the substrate layer. Because the electrode slice of this scheme has certain flexibility, probably there is the condition that the electrode slice bends after tearing first, two from the type membrane, inconvenient and skin are attached, simultaneously, tear the whole substrate layer in back with the type membrane with the second and all have the viscose, do not have the place that conveniently holds in hand, consequently increased the third from the type membrane. When the electrode plate sticking device is used, the first release film and the second release film are torn, the third release film is held by a hand, the third release film has certain mechanical strength, the electrode plate can be kept not to be bent, and after the electrode plate is stuck, the third release film is torn again to complete the whole work of sticking the electrode plate.

In this embodiment, as shown in fig. 10, the aspect ratio of the electrocardiac electrode sheet is greater than 2. The design of the strip shape can ensure the distance between the input electrode and the output electrode and has the smallest volume, thereby having the least influence on the wearer.

In this embodiment, the entire electrocardioelectrode plate is a strip, which is slightly wider at the position of the main machine and narrower at the position of the lead. The electrode plates of the scheme are not regular patterns, but are as small as possible under the condition of meeting the functions.
