Electrocardiograph electrode plate

Abstract

The invention discloses an electrocardiograph electrode plate which comprises a substrate. Two plastic sheets are laminated to form the substrate, two metal sheets are arranged between the two plasticsheets, gaps are reserved between the two metal sheets, and openings are formed in the plastic sheets and correspond to the metal sheets, so that two surfaces of each metal sheet can be exposed on the upper surface and the lower surface of the substrate and can be in contact with the surface of the skin of the left chest of a human body and an electrocardiograph signal acquisition device; spacesbetween the two plastic sheets and the metal sheets are filled with adhesive; the upper surface of the substrate is used for being in contact with the surface of the skin of the left chest of the human body, and the opening in the upper surface of the substrate are formed at far ends of the two metal sheets which are far away from each other; the lower surface of the substrate is used for being incontact with the electrocardiograph signal acquisition device, and the openings in the lower surface of the substrate are formed in near ends of the two metal sheets which are far away from each other. The electrocardiograph electrode plate has the advantages that the metal sheets are embedded, the unique openings are formed in the substrate, and accordingly the distances of sites, which are in contact with the surface of the skin of the left chest of the human body, of the metal sheets can be smartly increased.

Description

technical field [0001] The invention relates to an electrocardiographic electrode sheet, which belongs to the technical field of medical instruments. Background technique [0002] As an element of reflecting heart beat, ECG signal is often used in clinical diagnosis of cardiology. With the improvement of living standards, people pay more attention to their own health on the basis of pursuing portability. Portable ECG signal acquisition devices are becoming more and more popular, but there are still many limitations in their use environment, and they cannot fully meet the needs of people. The pursuit of portability, there is still room for improvement in technology. [0003] Such as the wearable ECG recorder disclosed in patent CN303693084S, the recorder is composed of a portable ECG acquisition device and an electrocardiogram, the acquisition device and the electrocardiogram are connected by a metal button, and attached to the surface of the human skin for measurement ECG ...

With the improvement of living standards, people pay more attention to their own health on the basis of pursuing portability. Portable ECG signal acquisition devices are becoming more and more popular, but there are still many limitations in their use environment, and they cannot fully meet the needs of people. The pursuit of portability, there is still room for improvement in technology

[0003] Such as the wearable ECG recorder disclosed in patent CN303693084S, the recorder is composed of a portable ECG acquisition device and an electrocardiogram, the acquisition device and the electrocardiogram are connected by a metal button, and attached to the surface of the human skin for measurement ECG signal, currently there are three problems in this type of ECG recorder: (1) The exposed metal buttons are conductive, and the contact surface is not smooth. In the water environment, there is conductive substance water between the metal buttons, which is easy A short-circuit connection will cause the collected myocardial electrical signals to be unstable, and accurate ECG waveforms cannot be collected, so that current wearable ECG recorders generally cannot work in water environments; (2) The connection between metal buttons may Rotating, unstable, easy to fall off due to strenuous exercise, not suitable for ECG signal acquisition under intense exercise; (3) Wearable ECG recorders are often miniaturized, which will cause It is too close to pick up the myocardial discharge status signals at different positions, which is not conducive to the doctor's clinical diagnosis
