Technical Field

The utility model relates to the technical field of medical equipment, in particular to an electrode assembly for electrocardiograph detection and a wearable electrocardiograph detection device.

Background

Taking 24-hour dynamic electrocardiographic examination as an example, a portable electrocardiographic detection device is generally worn on a person to be detected, and the existence of arrhythmia of the person to be detected is known through 24-hour electrocardiographic monitoring, so that compared with the traditional electrocardiographic detection, the probability of capturing cardiac events is increased through prolonging the monitoring time.

Such electrocardiographic detection devices require the device to be worn by the person being detected. As with in-home electrocardiographic monitoring, the locations of the lead electrodes of the device, including relative to the scapula, collarbone, sternum, etc., between ribs, etc., require canonical placement to accurately measure electrocardiographic activity. Unlike in-hospital electrocardiographic monitoring, some lead electrodes are worn for a long time, and the person to be tested may engage in normal daily activities, so that the lead electrodes are easy to fall off from the body surface of the human body due to the lead wire, under such conditions, the general personnel do not have accurate lead electrode setting position judging capability, and when the trace of the original lead electrode or electrode sheet on the body surface of the person to be tested disappears due to the overlong lead electrode falling time, the lead electrode application is recovered to cause trouble for the person to be tested, thus the electrocardiographic detection invalid time is prolonged, and the dynamic electrocardiographic examination is invalid or the expected effect is not achieved.

Disclosure of Invention

The utility model provides an electrode assembly for electrocardiograph detection and a wearable electrocardiograph detection device.

In order to solve the above problems, the electrode assembly for electrocardiograph detection and the wearable electrocardiograph detection device provided by the utility model solve the problems by the following technical points: the electrocardio detection electrode assembly comprises a patch assembly provided with a lead electrode, a bottom plate and an annular patch, wherein the annular patch is attached to the bottom plate and can be separated from the bottom plate by tearing; the patch component is used for being attached to the bottom plate at one side contacted with the body surface of the human body, and can be separated from the bottom plate through tearing; the annular paste is of an annular structure with a central hole on the inner side, and an attaching area of the patch assembly on the bottom plate is located in a coverage area of the central hole on the bottom plate.

As described above, when the existing wearable electrocardiograph detection device is used and the lead electrode falls off, when the user does not have the ability of judging the setting position of the lead electrode and the original indentation on the body surface of the user disappears, the lead electrode cannot be recovered to the situation that the lead electrode is attached to the human body to achieve the monitoring purpose, so that the dynamic electrocardiograph detection is invalid or the expected effect cannot be achieved, no other better mode is available in the prior art to solve the problem, based on the background, an electrocardiograph detection electrode assembly is proposed, and the electrocardiograph detection electrode assembly is particularly suitable for the wearable electrocardiograph detection device used outside a hospital, and the specific structural composition comprises: when the lead electrode is separated, the user can be helped to restore the lead electrode to the monitoring state by himself.
