Portable wireless cardiogram monitor

Abstract

The invention relates to a portable type wireless ECG monitoring device of the medical treatment wardship technical field. In the invention, an electrocardiosignal preamplification module uses negative feedback differential amplifier circuits to carry out one-stage size-expansion on gathered electrocardiosignals; after being enlarged, the electrocardiosignals are transmitted to a microprocessor which comprises an operational amplifier, a flash module, an AD converter, an MAC, a heart rate identification module and a peripheral interface; a wireless transceiving module transmits exceptional electrocardiosignals to a USB transceiving module by using Zigbee protocol in a wireless way; a USB transceiving module receives the exceptional electrocardiosignals transmitted by the wireless transceiving module; and the USB transceiving module is connected with a peripheral device. The portable type wireless ECG monitoring device is characterized by small volume, lower power consumption and wireless transceiving.

Description

technical field [0001] The invention relates to a device in the technical field of medical devices, in particular to a portable wireless ECG monitoring device. Background technique [0002] Cardiovascular disease is one of the main diseases that threaten human life. Due to the failure to detect the lesion in time for early rescue, many heart disease patients are often very easy to die. Electrocardiogram is the main basis for the treatment of such diseases. It has the advantages of reliable diagnosis, simple method and no harm to patients. It is becoming more and more important in modern medicine. The conventional electrocardiogram is the electrical activity of the heart recorded by the electrocardiograph when the patient is lying still. It lasts only a few seconds to 1m and can only obtain a small amount of information about the state of the heart. It is also very low. Therefore, it is necessary to monitor the patient in real time for a long time and record the patient's E...

Problems solved by technology

However, with the development of electronic technology and computer technology, people put forward higher and higher requirements for its functions, such as graphic display, network connection, real-time diagnosis and other advanced functions that used to be realized by PCs have also become necessary basic functions. , which will make the overall volume of the device larger and require more batteries for power supply, which will cause inconvenience to the wearer

[0004] After searching the existing technical documents, it is found that the Chinese patent application number is 200710003350.3, and the patent name is "A Remote Wireless ECG Real-time Monitor". This patent includes the acquisition and processing of ECG signals and the wireless communication part. The wireless communication part adopts GSM / GPRS wireless transceiver scheme, the power consumption of real-time wireless transmission is very high, and its price is expensive, and other functions of PDA or mobile phone are completely unnecessary for most patients, so the practical wireless ECG in China so far The field of monitoring products is still blank
