Radio remote monitoring system for cardiogram

Abstract

The radio remote electrocardiac monitoring system of the present invention consists of three parts including patient's electrocardiac monitoring instrument, monitoring center in the hospital and public communication network for connection. The communication method between the monitoring instrument and the monitoring center is one client terminal / server system, in which the monitoring instrument is radio accessed via GPRS to Internet for data communication with the monitoring center and can store the acquired electrocardiogram and transmit it via USB interface to computer. The system adopts triple monitoring capable of obtaining most of the electrocardiac for clinical use, possesses both dynamic electrocardiac monitoring function and radio remote electrocardiac monitoring function, makes it possible to lower the death rate of heart disease patients and has important clinical significance on early diagnosis of heart disease.

Description

technical field [0001] The invention belongs to a medical monitoring system, in particular to a three-lead ECG wireless remote monitoring system. Background technique [0002] ECG signal is one of the earliest bioelectrical signals studied and applied clinically by human beings. It is easier to detect than other bioelectrical signals and has a more intuitive regularity. It is still one of the important research objects in the field of biomedical engineering. Before the heart contracts mechanically, the myocardium undergoes electrical excitation in advance and releases it to various parts of the body, thereby generating potential differences at different parts of the body surface. The continuous curve that traces this changing potential difference in chronological order through the body surface is the electrocardiogram. The conventional electrocardiogram is the electrocardiographic activity recorded by the electrocardiograph when the patient is lying still. It generally has 1...

Problems solved by technology

[0008]TTM system is a miniature, light, cheap, easy-to-operate ECG monitoring tool that is not limited by time and region. However, this device also has some disadvantages: it cannot capture very transient arrhythmias, it cannot detect asymptomatic arrhythmias or segmental changes, and it needs a telephone to contact the TTM center, etc.

[0009] The mobile-oriented ECG monitoring system can solve these problems. This research was carried out relatively early in foreign countries. Countries such as Europe and the United States began relevant research as early as the mid-1990s when the 2G digital mobile network was put into operation. Many universities have conducted research on telemedicine systems based on mobile communication technology. Among them, the Mobile Telemedicine Testbed project conducted by Maryland State University in the United States was carried out earlier and achieved certain results. This project began in 1996 and mainly focused on research and utilization The feasibility and practicability of mobile communication technology to transmit important physiological information of patients to the emergency center in the ambulance. In order to ensure sufficient bandwidth, it uses a mobile phone array composed of 2 to 8 GSM mobile phones as the communication platform. The system It has been tested clinically and achieved satisfactory results; most countries in Europe use the platform of mobile communication for telemedicine. It is because the geographic environment in Europe determines that it can use mobile communication for telemedicine; a company in Australia has developed a handheld ECG monitor and has passed the US FDA (US Food and Drug Administration) certification; while in Asia, Nanyang Technological University in Singapore has also carried out a similar research project for the transmission of ECG data on the ambulance; some domestic ECG transmission schemes are to convert the ECG information into audio information after modulation, and send it to the wired telephone through the mobile phone on, then demodulate, technically speaking, this is no different from TTM

Some companies adopt the scheme of collector + transmitter (PDA or mobile phone), which will inevitably lead to high prices, and other functions of PDA or mobile phone are not necessary for most patients
