Super-long time history electrocardiographic recording system by wireless telemetery

Abstract

The invention provides a super-long time history electrocardiographic recording system by wireless telemetery. The system comprises an electrocardiocorder, a data reader and a computer, wherein the electrocardiocorder comprises an electrocardio-electrode, an electrocardio-signal amplification module, an MCU (microcontrol unit), a Nand-flash memory, a communication path control unit and a wireless radio frequency communication module; an interference conversion chip for converting USB (universal serial bus) to SPI (serial peripheral interface) is built in the data reader; the data reader is communicated with the electrocardiocorder through an SPI interface, and is communicated with the computer through an USB interface; the wireless radio frequency communication module communicates with a radio frequency receiving module through a RF (radio frequency) wireless radio frequency transmission and receiving circuit. The system is low in power consumption, high in system integrity, strong in operability and wide in application field, can be used for realizing constant 30-day super-long time electrocardiographic recording by virtue of the wireless telemetery, and has a remarkable clinical diagnosis meaning.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an electrocardiogram recording system, in particular to a wireless telemetry ultra-long-term electrocardiogram recording system. Background technique [0002] Cardiovascular disease is a relatively common disease and one of the main diseases that threaten human life. Electrocardiogram (ECG) is the main basis for diagnosing such diseases. The electrocardiogram recorder records the electrocardiogram signal for a long time, so that the detection rate of the electrocardiographic change is leapfrogged, and it can also reveal the electrocardiographic changes that do not appear in the supine state, and assist in the analysis of these changes and heart rate, daily life , symptoms, body position and other changes in the relationship between electrical activity, so that the clinical application of electrocardiogram to a new stage. At the same time, it has the advantages of reliable diagnosis...

AI Technical Summary

Problems solved by technology

TF card is a storage device commonly used in portable consumer electronics, but if it is used in a long-term ECG recording system, it will cause the following problems: reduce system integration; reduce data security, patient ECG data loss or Increased chance of theft; increased chance of product damage

This patent can only provide the current 24-hour data and events through circular recording, and does not give a satisfactory solution to the ultra-long-term ECG recording
