Description

technical field [0001] The invention belongs to a medical information processing tool for personal use, in particular to a method and device for remote mobile monitoring of electrophysiological data based on a wide area network. technical background [0002] Most of the patients who die from cardiovascular diseases (coronary heart disease, hypertension) are sudden acute events in society, and the precious time for early diagnosis and treatment is lost, leading to death. Before the onset of an acute event, the patient's ECG, blood pressure and other electrophysiological parameters have already experienced aura disturbance. If these abnormal symptoms are detected early and treated in time, the patient's life can be saved. In the 1980s, U.S. Patent No. 4635646 and others successfully developed an analog FM telephone transmission ECG remote monitoring system. When the patient felt unwell, the real-time ECG was transmitted to the receiving tracing system of the hospital through a...

AI Technical Summary

Problems solved by technology

[0004] 1. With the existing fixed-line ECG remote monitoring technology, the user must find a fixed-line phone, dial the fixed-line phone of the receiving end device, and get a response before transmitting. Only one user is allowed to use it online, and other users can only wait until the line is free. To continue dialing call transmission, it cannot meet the needs of cardiac acute event monitoring

[0005] 2. The existing digital mobile communication network remote monitoring technology can only use one of the digital mobile communication networks, GPRS or CDMA, and cannot be compatible with digital mobile communication networks of different standards, cannot use 3G digital mobile communication networks, and cannot access external other networks for digital communication

[0006] 3. Existing technologies U.S. Patent Nos. 6,665,385, 6,694,177, etc. have adopted a fixed telephone network, a wireless paging network, and a satellite communication network as backup data channels for remote monitoring. As mentioned above, the wireless paging network is limited to a technical model and cannot The transmission of ECG graphics can only transmit some simple data that has been compressed and processed. The satellite communication network is expensive, and at the same time, it needs to be connected with different data receiving and sending devices. Some technologies use the USB interface of the PDA handheld computer to download the data to the computer. PC, and then log in to the Internet for transmission, these existing technologies are extremely inconvenient to operate and use

With the development of digital mobile communication technology, the network bandwidth and speed have been greatly improved, and the power consumption and cost of mobile phones have been reduced. This data structure method and divided transmission method are obviously backward and cannot meet the requirements of rapid analysis and diagnosis of acute cardiac events.

[0009] 6. The existing technology has no safety information data management function, cannot provide legal basis and medical evidence for possible medical liability disputes, and lacks the remote call for help function in the non-monitoring state

[0010] 7. The existing technology lacks an internationally unified reference calibration voltage for the analysis and calculation of ECG data, and there is a large error in the quantitative calculation of the ST segment involved in the diagnosis of acute myocardial infarction, acute myocardial ischemia, and painless myocardial ischemia.

Chinese patent 91102750.5 provides a calibration voltage signal by an automatic gain control circuit, but errors are likely to occur when the ECG signal is at a critical value or when the baseline fluctuates
