Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of electrocardiogram acquisition and analysis, and specifically relates to a device capable of realizing collection and processing of an electrocardiogram signal. BACKGROUND OF THE INVENTION An electrocardiograph is one of the important instruments for diagnosing current clinical tests and is a necessary means for doctors to make a correct diagnosis. At present, a wide range of electrocardiographs are widely divided into two types, one is a specialized electrocardiograph, and the other is an electrocardiograph assembled from an electrocardiograph and an ordinary PC.

The purpose of the ECG machine and the ECG workstation is to collect the patient's ECG waveform and provide the doctor with the condition information for analysis and diagnosis.

From the point of view of digital electrocardiogram, the working principle of ECG machine and ECG workstation is basically the same, but the implementation is slightly different. From the working principle, both have the following basic modules or links, namely, ECG signal amplification module, signal digitization processing module, data storage module, data analysis module, display module and printing module. The function of the ECG signal amplification module is mainly to amplify the electrophysiological signal of the patient's body to facilitate the identification of the instrument; the function of the signal digitization processing module is to convert the electrophysiological signal into a digital signal that the machine can recognize; the digital storage module, its function The digital electrocardiographic signal is stored in the instrument; the data analysis module realizes the function of analyzing the collected data; the function of the display module is to let the doctor observe the electrocardiogram waveform while collecting the electrocardiogram, or realize the acquisition. After the playback; the print module prints the collected ECG, and this module in the ECG workstation can also print the analysis data and medical records.

The effect of electrocardiograph and ECG workstation: digitize the patient's electrophysiological signal, store and observe the signal, and generate diagnostic data useful to the doctor.

The existing ECG workstation system is structured as follows: The external part of the digital computer part of the temporary spare parts analog amplification system has

Digital interface

Install software security software (when executed). Yes, account for memory

Software (when exiting) Yes, occupying hard disk, not moving

Software (after uninstallation) partially exists

Software (boot mode) Yes, Auto

ECG data Yes, it occupies the hard disk and is not easy to move. Features Only a simple digital system Specializes the general purpose computer The current ECG machine and ECG workstation are used to trace the ECG waveform for clinical diagnosis by medical personnel. They all have working modules such as ECG signal amplification module, signal digitization processing module, data storage module, data analysis module, display module and printing module.

The structure of the electrocardiograph is that each module is concentrated on the electrocardiograph. As a result, the complete ECG machine has multiple functions such as collection, digitization, storage, analysis, display and printing, and can work independently. The advantage is that it is fully functional, and the disadvantage is often that it is too bulky and inconvenient to use.

The ECG workstation is slightly different from the ECG machine. Its hardware uses an ECG collector and a general-purpose computer and its peripheral devices (such as laser printers) to reduce investment and give full play to the potential functions of the instrument. That is to say, in the ECG workstation, the functions of the data storage module, the data analysis module, the display module and the print module are realized by the conventional computer and its peripheral devices, and the functions of the electrocardiographic signal amplification module and the signal digitization processing module are realized. It is implemented by the ECG collector. In this way of working, the dedicated ECG collector is much smaller in size than the independent ECG machine, but it needs to be installed in the computer. Specialized ECG software is installed, and the ECG data is stored in the computer, so in fact, the entire workstation is still bulky, and the requirements for the environment and conditions are still relatively demanding.
