Problems solved by technology

[0011] But above-mentioned these household electrocardiographs generally have lead number few, the amount of information that provides is on the low side, the lead that some instruments are used is not the standard 12 leads that medical personnel are familiar with, so existing household electrocardiograph device The clinical reference value is not great, and some instruments still have certain safety hazards and performance defects, which are difficult to meet clinical needs

Embodiment Construction

[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. And, in this embodiment, take the 12-lead electrocardiogram as an example to illustrate its working mode, but, as known, the principle of the electrocardiograph and other electrical signal amplifying instruments (such as electroencephalograph) is basically the same, and in the long In the history of development, in addition to the above-mentioned twelve leads, there are more than one hundred other leads in the electrocardiogram. The scope of application of the present invention is not limited to the twelve-lead electrocardiogram machine. Vector graphics machine or other multi-channel electrophysiological signal amplification equipment.

[0046] see figure 1 According to the first embodiment of the present invention, it is a twelve-lead synchronous dynamic ECG recording box (such as a twelve-lead Holter, ECG monitor or similar device). Among them, the electrod...

Abstract

The invention relates to a digital pick-up device for body surface cardiac electric signals, and belongs to the field of medical appliances. The digital pick-up device adopts multiplexing and single-stage single-channel amplifier structures, and is a virtual instrument structure adopting a single-channel A / D convertor to realize synchronous acquisition of twelve-lead body surface cardiac electricsignals. The instrument is provided with an isolating communication part and a detachable data storage device, and can meet corresponding medical electrical safety standard. The digital pick-up device has the advantages of small volume, low electric power consumption and low cost, is designed by taking EMC as reference, and is particularly suitable for popularization and application of families.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a digital pickup device for body surface cardiac electric signals, in particular to a portable, digital multi-lead synchronous electrocardiograph suitable for home use. Background technique [0002] Body surface electrocardiogram is an important auxiliary diagnostic tool for cardiovascular diseases. At present, the common clinical instruments for surface cardiac electrical signals mainly include asynchronous (single-channel) or synchronous (multi-channel) 12-lead electrocardiogram machines and ECG monitors. and Holter. At present, this type of equipment is mainly used in the hospital environment. The volume, weight and power consumption of the first two machines (ECG machines and monitors) are still relatively large, and it is difficult to achieve the level of handheld consumer electronics products. At the same time, the complex electromechanical structure makes its p...
