Electrocardiosignal monitoring system

Abstract

The invention discloses an electrocardiosignal monitoring system, and belongs to the technical field of physiological characteristic monitoring. The system comprises a monitoring end, the monitoring end acquires an electrocardiosignal and a motion body position signal respectively, the electrocardiosignal is modulated into a first carrier wave with first frequency, the motion body position signal is demodulated into a second carrier wave with second frequency lower than the first frequency, and is sent to a pick-up unit of a user terminal close to the monitoring end, and the user terminal modulates the carrier waves to obtain the electrocardiosignal and the motion body position signal and presents the electrocardiosignal and the motion body position signal for a user to view. According to the electrocardiosignal monitoring system, hardware requirements of electrocardiosignal transmission are simplified, the transmission power consumption is lowered, and the purpose that real-time and timely electrocardiosignal transmission and long-term electrocardiosignal monitoring and continuous data recording are supported simultaneously is achieved.

Description

technical field [0001] The invention relates to the technical field of physiological feature monitoring, in particular to an electrocardiographic signal monitoring system. Background technique [0002] With the development of technology, the size of ECG monitoring equipment is becoming more and more portable, from the large monitoring equipment that can only be fixed in the hospital and cannot be moved at will, to the Holter, commonly known as the "back box", to smaller and more Wearable ECG monitoring equipment that is easier to carry around. The evolution of the equipment, especially the portability, means that the patient's ECG signal can be monitored for a longer period of time, and it will not bring additional burden to the patient and affect the normal life of the patient. In this way, the routine activities of patients in the monitoring or diagnosis process can be restored to make the detection more accurate. [0003] But the wearable ECG monitoring device in the pri...

Problems solved by technology

However, the power consumption requirements of these two wireless transmission methods are relatively large, which makes it impossible to perform long-term records (for example, records of more than 7 days)

[0005] For some wearable ECG monitoring devices that use Bluetooth for wireless transmission, although the power consumption has been greatly improved, it is necessary to ensure that the pairing with the user terminal is successful before Bluetooth transmission, and different Bluetooth chips are in use Compatibility on different user terminals is not stable enough

[0006] Moreover, wearable ECG monitoring devices using the above wireless transmission methods usually need to be powered by rechargeable batteries, and the timeliness in actual needs and use cannot be guaranteed.

[0007] 2) If only long-term recording of ECG data is not equipped with wireless transmission function, patients often need to complete long-term wearing (such as 7 days to 14 days) before they know the possible previous wearing process (such as possible third arrhythmia, that is, abnormal ECG signals cannot be fed back to patients or medical monitors in time

[0008] 3) If the patient feels uncomfortable during the wearing process, they can only manually record the time of symptom occurrence and symptom type, which is inconvenient to operate, and the correlation with the monitored ECG signal is not enough, making it difficult for medical monitors to make judgments Whether symptoms are due to, or ruled out, cardiac abnormalities
