Example Embodiment

[0045] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in this embodiment, a twelve-lead electrocardiogram is taken as an example to illustrate its working method. However, as is known, the principles of electrocardiographs and other electrical signal amplification instruments (such as electroencephalographs) are basically the same. In the history of development, in addition to the above-mentioned twelve-lead ECG, there are more than one hundred other leads in the ECG. The scope of application of the present invention is not limited to twelve-lead ECG machines. For example, it can also be a Frank lead ECG. Vector graphics machine or other multi-channel electrophysiological signal amplification instrument.

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

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 electric signals. 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...
