Description
Technical Field
The utility model relates to the technical field of electrocardiograph recorders, in particular to a novel 3-lead dynamic integrated electrocardiograph patch.
Background
Electrocardiogram (ECG) technology is an important medical tool for monitoring and recording cardiac electrical activity. Among them, the tri-conduction dynamic electrocardiographic technique is an advanced electrocardiographic monitoring method, and is generally used to more comprehensively evaluate heart activity in order to more accurately diagnose heart diseases. The three-lead dynamic electrocardiography technique is achieved by continuously recording cardiac electrical activity, typically for 24 hours or up to 14 days. Unlike a standard static electrocardiogram, it allows a physician to view the heart activity of a patient in different situations in daily life. This helps detect arrhythmias and anomalies that are not easily captured in a short-time long static test.
Conventional three-lead (three-channel) dynamic electrocardiographic monitoring typically acquires electrocardiographic signals through a plurality of electrode pads attached to the patient's body, as shown in fig. 1. The electrode plate is connected with a recorder on the patient through the shoulder strap back through an electrocardiograph lead. In conventional 3-lead electrical leads and conventional electrode pad configurations, the number of electrode pads varies from three to seven, and these electrode pads are located on different body parts, typically including the chest and extremities. This technique allows a physician to obtain multiple angles of electrocardiographic data to more accurately assess cardiac function.
Because the traditional 3-lead electrocardiograph is huge in size, and in addition to the lengthy and heavy electrocardiograph lead wires, the comfort of a patient is poor when the patient wears the electrocardiograph, and meanwhile, the recorded electrocardiograph signals can be interfered due to accidental pulling of the lead wires, so that the electrocardiograph signals cannot be analyzed. This type of recorder can greatly affect the wearing comfort of the patient and severely affect the patient's daily life if the patient needs to wear the recorder for several days (2 to 14 days). To improve this disadvantage of the conventional 3-lead recorder, a technician develops a more portable electrocardiographic patch, and for example, publication nos. CN206080511U and CN208910241U disclose a single-lead electrode patch, respectively, and the wearing mode of the single-lead electrode sheet is as shown in fig. 2. However, the single-lead electrocardiograph patch has the following problems:
1. Not corresponding to a strictly defined channel, the doctor is uncertain about the meaning represented by the measured electrocardiographic signal;
2. when the recorder is interfered, the auxiliary signal quantity is insufficient, and an extra electrocardio channel cannot be provided for a doctor to make accurate diagnosis;
3. The single-lead or 2-lead electrocardiograph paste is very small, so that the distance between the electrodes is very short, the amplitude of the captured electrocardiograph signal is very small, the captured electrocardiograph signal is easy to interfere, the electrocardiograph paste cannot be used for electrocardiograph analysis, a patient possibly needs to wear the electrocardiograph paste repeatedly, and extra burden is caused to the patient.
In summary, it is difficult for existing dynamic electrocardiographic techniques to achieve a balance between comfort and signal accuracy.

As shown in fig. 3 to 5, the present application includes a novel 3-conductive dynamic integrated electrocardiographic patch, which includes: the electrode contact is arranged on the substrate.

The substrate comprises a front surface and a back surface, the electrode contact points are arranged on the back surface, and the front surface of the substrate is provided with an electrocardiograph recording device connector; the electrode contact point is connected with the joint of the electrocardiograph recording device through the electrode connecting component.
The electrode contact point is used for collecting electrocardiosignals, the collected signals are connected to an electrocardio recording device connector based on connecting components such as a lead, a conductive film and the like, and then the signals are transmitted to a dynamic electrocardio recording device (not marked in the figure) through the electrocardio recording device connector. The specific shape of the matrix is adaptively controlled according to actual requirements and cost, and can be round, rectangular, star-shaped or rectangular plus four-branch anti-body type as shown in fig. 3-4, in order to avoid too many adhesion parts with the body of a wearer, the adhesion effect is influenced by the trend of muscles in the action of the wearer, and most of the matrix adopts star-shaped or the mode that each electrode contact point is distributed with an independent adhesion branch in fig. 3-4.
In particular, the connection method of the substrate and the electrode contact point can be based on fixed connection and detachable connection, such as: the connection modes in the prior art such as button structure or clamping structure are realized; the electrical connection mode of the electrode contact points and the electrocardiograph recording equipment connector and the used connection parts are realized based on the traditional electrocardiograph paste circuit connection in the prior art; the specific structure of the connector of the electrocardiograph recording device and the specific connector of the locking structure are adaptively set according to the type and model of the dynamic electrocardiograph recording device.
The electrocardiograph patch is an integrated electrocardiograph patch, one electrocardiograph patch comprises 5 electrode contact points for acquiring electrocardiograph signals, and the positions of the 5 electrode contact points on a substrate and the distances between the contact points are shown in figure 6.
The first electrode contact point and the second electrode contact point are a group and are arranged at the uppermost position of the matrix, the first electrode contact point and the second electrode contact point are positioned on the same straight line, and the distance between the first electrode contact point and the second electrode contact point is 11cm;
the fourth electrode contact point and the fifth electrode contact point are a group and are arranged on a straight line, the distance between the fourth electrode contact point and the fifth electrode contact point is 7cm, and the fourth electrode contact point and the fifth electrode contact point are positioned at the lowest part of the matrix;
the perpendicular bisector of the line connecting the two contact points at the upper part coincides with the perpendicular bisector of the line connecting the two contact points at the lower part;
The third electrode contact point is arranged on the middle vertical line of the upper and lower groups of electrode contact points; the third electrode contact point is 3.5cm from the center point of the connection line between the two contact points above and 4.5cm from the center point of the connection line between the two contact points below.
The wearing method of the 3-guide dynamic electrocardiographic patch is shown in fig. 7. The 3-conductor dynamic integrated electrocardiograph patch is placed below the collarbone, and the center line of the electrocardiograph patch is aligned with the sternum, so that the patch is convenient for men and women to wear.
In the electrocardiographic data acquisition technology, the definition of the I, II and III channels and the chest lead channels of the electrocardiographic limb leads and the electrode positions are shown in figure 8.
The placement of the dynamic electrocardiogram lead electrode comprises: the right shoulder upper part (RA), the left shoulder upper part (LA), the left lower abdomen (LF) and the right lower abdomen (RF) form I, II, III, aVR, aVL, aVF leads of the electrocardio limb leads, and the frontal plane electrocardio interaction is reflected.
Chest lead locations include: the right sternum edge is between the 4 th rib (V1), the left sternum edge is between the 4 th rib (V2), the intersection between the left collarbone midline and the 5 th rib (V4), the midpoint of the connection between the V2 and the V4 (V3), the left anterior axillary line V4 level (V5) and the left anterior axillary midline V4 level (V6) reflect the transverse electrocardiographic activity.
The correspondence between the positions of the integrated electrocardiograph patch and the electrode patch of the traditional lead in the application is as follows:
Electrode contact 1 corresponds to the LA electrode position of a conventional lead.
Electrode contact 2 corresponds to the RA electrode position of a conventional lead, which is spaced apart from electrode contact 1 by 11cm.
The electrode contact 3 corresponds to the V1 or V2 position of the conventional lead, and has a vertical distance of 3.5cm from the straight line formed by the center points of the contacts 1 and 2 and a vertical distance of 3.5cm from the contact 5.
Electrode contact 4 corresponds to the LF electrode position of a conventional lead, which is spaced 7cm from contact 5.
Electrode contact 5 corresponds to the RF electrode position of a conventional lead.
The corresponding relation between the electrocardio channel formed by the 3-lead integrated electrode paste and the traditional 3-lead electrocardio channel is as follows:
the electrocardiographic data formed by the second electrode contact point and the first electrode contact point is equivalent to the I channel of the limb lead.
The electrocardiographic data formed by the second electrode contact point and the fourth electrode contact point are equivalent to the II channel of the limb lead.
The electrocardiographic data formed by the first electrode contact point and the fourth electrode contact point are equivalent to the III channel of the limb lead.
The electrocardiograph data formed by the fifth electrode contact point and the Wilson zero point are equal to the chest lead V1 channel.
When the electrode is actually worn, like the traditional 3-lead electrode is pasted and placed at the same position, the specific positions of the electrode contacts have a certain adjustment space, and the corresponding relation between the 3-lead electrocardiograph paste and the traditional 3-lead electrocardiograph channel is not influenced by the slight difference of the positions of the contacts. The 3-channel electrocardiosignals collected based on the 3-conductive integrated electrode paste have a one-to-one correspondence with the traditional 3-channel electrocardiosignals, so as to ensure that accurate electrocardiosignal vectors can be collected
After the technical scheme of the application is used, 5 electrode patches are not required to be processed independently, and only one electrode patch is required to be processed, so that the requirements can be met. When the integrated electrocardiograph paste is stuck to a wearer, 5 times of electrode paste placement are not needed, and only the 3-conductive integrated electrode paste is needed to be placed once, so that the integrated electrocardiograph paste is very simple and convenient to use, and the working efficiency is greatly improved. Compared with the data acquisition mode of the single-lead electrode slice, the 3-lead integrated electrode patch placement mode ensures the rigor of an electrocardio channel; meanwhile, because the electrocardio paste matrix is smaller in size, and 5 electrode contact points are arranged on the same matrix, compared with a traditional multi-electrode plate acquisition mode, signal interference caused by extrusion of a recorder and pulling of the electrode contact points caused by body rotation and interference caused by muscle electric signals are reduced to the greatest extent, validity and high quality of the electrocardio signals are guaranteed, and a solid foundation is provided for subsequent quick and accurate electrocardio analysis.
