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 and health of urban people. In 2018, the national cardiovascular disease center published Chinese cardiovascular disease reports 2017 (summary). According to the calculation, the number of cardiovascular diseases in China is 2.9 hundred million, and the death rate of cardiovascular diseases accounts for more than 40 percent of the death rate of resident diseases, and is higher than that of tumors and other diseases at the top. For patients with cardiovascular and cerebrovascular diseases, it is very important to detect the electrocardiosignals all the 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 equipment is disclosed in patent invention with the name of disposable electrode sheet type conventional electrocardiographic lead wire, as No. CN 200720125633.0: a disposable electrode sheet type conventional electrocardiogram lead wire belongs to a lead wire for monitoring and tracing a conventional electrocardiogram, a cable (5) is connected with a shielding rubber line (3) through a fixed connection deconcentrator (4), the tail end of the shielding rubber line (3) is connected with a joint (1), and a working surface of the joint (1) is bonded with a disposable adhesive electrode (2). 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 stick type electrode slice, so that the stable contact between the electrodes 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 electrodes is changed into the disposable use, the requirement of public health is met, and the disposable electrode has a simple, convenient and effective structure and is 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 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. Install bottom body detachable on the host computer like this, 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 ecg monitor, 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, the electrode buttons are designed for large-scale medical equipment, the size of electrode plates matched with the wearable electrocardio-type breast patches is too large, when the wearable electrocardio-type breast patches are in single lead, the wearable electrocardio-type breast patches are small in size, patients can move, when a multi-lead structure appears, the electrode plates of the equipment are more, the patients cannot move conveniently, or do exercise or bath, and popularization of the medical products for potential patients is greatly hindered.

Therefore, it is necessary to design an electrode plate structure, which is light in structure, does not need an external connecting wire, does not affect daily work and life when patients are matched, and improves the comfort level of human body on the basis of confirming the performance of the electrode plate.
