12 lead wireless remote electrocardiograph monitoring system

Abstract

The invention relates to a 12 lead wireless remote cardiac electric monitoring system and pertains to the field of medical monitors. The system comprises two parts of a cardiac electric monitor and a monitoring center set in hospitals. The monitor comprises a data collection unit, a storage unit, a singlechip unit, a communication unit, a human-computer interaction unit and an electricity supply unit, wherein, the data collection unit adopts 12 lead synchronous cardiac electric monitoring, after the data collected by the data collection unit are treated by the A / D switching circuit, the cardiogram is displayed on a liquid crystal display (LCD) panel and then recorded in the storage module, meanwhile cardiac electric analysis is carried out, the analysis result is stored in the storage module, if users need to wirelessly transmit cardiac electricdata or a analysis report, the cardiac electricdata or the analysis report is read to the sending buffer, then the data is sent to the computer of the server of the monitoring center. The cardiac electric monitoring system is characterized by small volume, high degree of intellectualization, reliable performances, low cost and convenient operation and can obtain most cardiogram information required in clinic.

Description

technical field [0001] The invention belongs to the field of medical electrocardiographic monitoring instruments, in particular to a 12-lead wireless remote electrocardiographic 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 ...

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] In the United States, many universities have conducted research on telemedicine systems based on mobile communication technology, among which Maryland State University has carried out earlier and achieved certain results The Mobile Telemedicine Testbed project, which started in 1996, is mainly to study the feasibility and practicability of using mobile communication technology to transmit important physiological information of patients from emergency vehicles to emergency centers. In order to ensure sufficient bandwidth, its use A mobile phone array consisting of 2 to 8 GSM mobile phones is used as a communication platform. This system has been used in clinical trials and has achieved relatively satisfactory results; most European countries use mobile communication as a platform for telemedicine. Europe already has a well-developed mobile communication network, and its technology is in the leading position in the world. The second reason is that Europe's geographical environment determines that it can use mobile communication for telemedicine; a company in Australia has developed a handheld ECG monitor, and It has passed the US FDA (US Food and Drug Administration) certification; 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 programs are The ECG information is modulated into audio information, sent to the wired telephone via the mobile phone, and then demodulated. 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 its high price, and other functions of PDA or mobile phone are not necessary for most patients
