Multifunctional auxiliary electrocardiogram monitoring device

Abstract

A multifunctional auxiliary electrocardiogram monitoring device comprises a chest strap, a first electrocardiogram signal input module embedded in the chest strap, a hardware system capable of being taken out and placed in the chest strap as well as a middle connecting part accessing an electrocardiogram signal acquired from the first electrocardiogram signal input module to the hardware system, wherein a second electrocardiogram signal input module is embedded in a PCB (printed circuit board) of the hardware system, the first electrocardiogram signal input module is two silver-plated metal dry electrodes/Agcl wet electrodes, the second electrocardiogram signal input module is two platy silver-plated metal dry electrodes, one end of two biforked ends of the middle connecting part is buckled with one silver-plated metal dry electrode/Agcl wet electrode, and the other end is in plug connection with the hardware system; the hardware system comprises an input interface circuit receiving an electrocardiogram signal and recognizing the type of the electrode, an analog front end preprocessing module, an electrocardiogram dedicated chip, an MCU (microprogrammed control unit), an SD card module, a communication module, a power management module and an OLED (organic light emitting diode) display screen. The multifunctional auxiliary electrocardiogram monitoring device is small in size and comfortable and free to wear, and people can wear the chest strap to measure the electrocardiogram and can touch the dry electrodes in the PCB with double hands to measure the electrocardiogram.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a multifunctional ECG auxiliary monitoring device. Background technique [0002] As we all know, cardiovascular disease is one of the most threatening diseases facing mankind today. At present, there are 290 million patients with cardiovascular and cerebrovascular diseases in my country, of which more than 3 million die from cardiovascular diseases every year. Since the onset of cardiovascular disease is very sudden, it is easy to lose precious time for early diagnosis and treatment. For this reason, the best way is to prevent it before it happens. Because daily heart monitoring is an important means of guaranteeing the safety of patients’ lives, abnormal signs can be detected in advance through daily heart monitoring, which can buy time for timely treatment. Daily monitoring of human heart conditions through ECG signals is an effective way to monitor the heart. However, since most...

Problems solved by technology

However, because most of the traditional ECG monitoring uses AgCl-Ag electrodes, electrolytic gel or adhesive needs to be used, and the three-electrode input mode with the right leg driving electrode is adopted, which is very inconvenient to measure, and its long-term use is very easy to cause Uncomfortable reactions such as skin allergies, so it is not suitable for long-term wearing in daily life
