Problems solved by technology

Moreover, the electrostatic charge on the clothes and the charge conductivity of the clothes will also affect the signal. Due to the accumulation of charges, the static charges cannot be released as soon as possible, which will cause the ECG signal to be covered or weakened by noise.

Embodiment Construction

[0021] As shown in Figure 2, an example of the present invention is based on the non-contact multi-lead ECG monitoring system of arrayed capacitive electrodes, including four parts of flexible arrayed capacitive electrodes 5, signal processing module, spraying device 7, and embedded terminal. Three arrayed capacitive electrodes 5, 4, and 9 are placed on the seat back 6, corresponding to the left upper limb (L), right upper limb (R) and left lower limb (F) of the human body. Hoffen's equilateral triangle. Spraying device 7 is placed at the left edge place of seat back 6, can determine whether to start spraying device according to the humidity of air, makes it remove surrounding electrostatic interference. The electrocardiographic processing module and the embedded terminal are all integrated on a printed circuit board 8, which is located in the inner area of ​​the center point of the seat back. The reference electrode 11 made of conductive fabric is placed on the chair cushion...

Abstract

The invention discloses a non-contact multi-lead electrocardiogram monitoring system based on array capacitor electrodes. The system comprises a plurality of capacitor electrodes. The plurality of capacitor electrodes are arranged on a seat backrest. Center of two adjacent capacitor electrodes are connected, so lines of centers of the plurality of capacitor electrodes form a polygon. A midpoint position of the polygon is corresponding to a heart position of a human body. The seat backrest is connected with a cushion. The cushion is fixedly provided with a reference electrode. The multi-lead electrocardiogram monitoring system is simple in structure, and can be directly used without any preparation in advance.

Description

technical field [0001] The invention relates to the field of ECG signal monitoring, in particular to a non-contact multi-lead ECG monitoring system based on arrayed capacitive electrodes. Background technique [0002] At present, more than 40% of the various diseases that cause the death of domestic residents come from cardiovascular diseases, and the commonly used method for diagnosing cardiovascular diseases is mainly electrocardiogram. In the traditional ECG monitoring system, Ag / AgCl disposable electrode sheets or suction cups with conductive glue are usually used. The disadvantage is that it must be in direct contact with the human body surface skin, and in order to have good contact and signal stability, it is necessary to It takes a long time to apply conductive paste on the skin surface. Traditional ECG monitors also require professionals to operate and observe. The electrodes of the traditional dynamic ECG monitoring system need to be in direct contact with the sk...
