Problems solved by technology

[0003] Because the above-mentioned electrocardiometer equipment must rely on special electrodes and lead wires, the required electrocardiographic signals can be collected. Therefore, the existing electrocardiometer equipment cannot directly use the computer system and its peripheral equipment. To directly form the automatic processing system of ECG data

Abstract

The electrocardial instrument with sound card for acquiring electrocardial signal includes a screen display module, a data memory module and an alarm module, as well as an electrocardial signal pre-processing unit, a sound card data acquiring module, and a WAV data converting module. The electrocardial signal pre-processing unit includes a hand touch electrode, an electrocardial signal amplifier, a sound card Line-In interface and a power source; the sound card data acquiring module has data buffer for buffer memory of the received electrocardial signal data; and the WAV data converting module completes the data conversion between the audio signal and the electrocardial signal. The present invention adopts the audio signal line and sound card of computer system directly, sets hand touch electrode in the peripheral, and is convenient and easy to replace.

Description

technical field [0001] The invention relates to the field of electronic medical instruments, in particular to a system and method for automatically processing data of an electrocardiometer by using a sound card to collect electrocardiographic signals through an audio signal input port on a computer operating platform. Background technique [0002] The electrocardiographic monitoring in the prior art generally requires the use of a special electrocardiograph to obtain electrocardiographic signals. At present, the electrocardiograph is basically composed of an internal power supply, a power converter that converts AC220V to DC, an LCD display, control operation keys, and human body contact electrodes and lead wires. The ECG signal connection line of the electrocardiograph is composed of 1 data communication line connected to the computer USB interface, 4 electrode clips, 6 electrode balls and other accessories. [0003] Because the above-mentioned electrocardiometer equipment...
