technical field

The utility model relates to the technical field of medical equipment, in particular to an electrocardiographic electrode and an electrocardiographic monitoring device containing the electrode.

Background technique

At present, with the advent of aging, the elderly need to know more and more about their own heart changes. At present, to do a heart test, you must go to the hospital and use the hospital's ECG equipment to detect it. However, due to the constraints of objective conditions, it cannot be done frequently Check the heart rate. The best time to detect heart disease is often delayed; in addition, the traditional inspection method connects many lead wires to the human body to collect ECG signals, which is cumbersome to use, and the ECG monitor is susceptible to falling off caused by the wearer's actions , or poor contact resulting in invalid test data. At present, there are 290 million people suffering from cardiovascular disease in my country. The electrocardiogram is an important means of detecting cardiovascular disease. The electrocardiogram collects bioelectrical signals through electrodes covered on the human body surface to record the rhythm of the heart's activity.

The most widely used is the Wilson lead system. The traditional lead system wires are easy to be entangled, and the complicated positions of the ten points must be completed by professionals. So now there are many companies trying to develop new lead systems to solve the above problems. Among them, the structure of the electrode is very important, because the most important thing of the lead system is to ensure the adequacy and consistency of the contact between the electrode and the human body. At present, flat electrode sheets or hemispherical electrodes are the most used in the new lead system, but the contact area with the human body is too small, and the electrode contact area will change when people breathe, so the consistency of contact cannot be guaranteed. The acquisition of the signal is greatly disturbed, and an electrocardiogram with diagnostic significance cannot be obtained.

It can be seen from this that it is possible to invent a new type of ECG electrode, which can ensure the contact area between the electrode and the human body to be larger and ensure the consistency of the electrode and the human body at the same time as the electrode size is as small as possible. Solving the problem of insufficient electrode contact in the new wearable lead system has become a technical problem to be solved urgently by those skilled in the art.

When the electrode contact surface is in contact with the electrode point of the human body, the handpiece is pressed by pressing the handpiece, which further causes the conductive spring seat to be pressed to the spring.

Further, the fixed sleeve is provided with an annular clamping seat, and the end of the conductive spring seat in contact with the conductive spring forms a bent portion outward, and the bent portion is clamped on the annular clamping seat.

Connected to the ECG monitoring device through a spring connection or a silicone base, the electrodes can be rotated and stretched within a certain angle or height range, so that the electrodes can be perfectly fitted on the skin with the body structure, and compared with traditional electrodes, the user is more comfortable higher degree.
