Electrocardiogram signal acquisition device

Abstract

The invention discloses an electrocardiogram signal acquisition device. The device comprises a signal acquisition module, a microprocessor and an interface control module, wherein the signal acquisition module is used for acquiring an electrocardiogram signal of a body surface of a human body; the microprocessor is used for controlling electrocardiogram signal acquisition and data transmission and is connected with the signal acquisition module and the interface control module; the interface control module is used for communicating with external equipment and is connected with the microprocessor; the signal acquisition module comprises two parts, namely a signal amplifier and a high-precision analogue-to-digital converter, is used for acquiring the electrocardiogram signal of the body surface and converting an acquired analogue signal into a digital signal which can be identified by the microprocessor, and is connected with the microprocessor; and the interface control module is used for data interaction between the microprocessor and a PC host machine or an electrocardiogram machine host machine (generally called host machine in the following text), and is connected with the microprocessor and the host machine. The device controls the signal acquisition module and the interface control module through the microprocessor, and can acquire the 12-lead electrocardiogram signal of the body surface by matching host software without other devices.

Description

technical field [0001] The invention relates to a movable electrocardiographic signal acquisition device, in particular to a PC-based body surface electrocardiographic signal recording device. Background technique [0002] At present, the electrocardiogram machines used in hospitals at all levels are bulky, simple in function, and expensive in cost. On the contrary, with the development of electronic technology, a large number of portable electronic devices are widely used in social life and professional scientific research because of their simple structure and convenient use. In the medical field, it is almost difficult for a 12-lead electrocardiograph on the surface of the body to get rid of the embarrassing situation in the above-mentioned structure, function and price. In the process of many electrocardiographs recording body surface ECG signals, due to the strong professionalism and randomness of the recorded data, the format of the recorded data is usually a non-stand...

AI Technical Summary

Problems solved by technology

In the process of many electrocardiographs recording body surface ECG signals, due to the strong professionalism and randomness of the recorded data, the format of the recorded data is usually a non-standard format customized by each manufacturer, which cannot be directly used by the user's computer. identification, the human body surface ECG data recorded by it cannot be analyzed, processed, stored and displayed on the user's computer

When more in-depth post-analysis and processing of the recorded ECG signals are required, the functions provided by the usual ECG machines are difficult to achieve
