Real-time wireless blood pressure monitoring system, blood pressure measuring device and blood pressure analysis method

Abstract

The invention discloses a real-time wireless blood pressure monitoring system, a blood pressure measuring device and a blood pressure analysis method. The system comprises the blood pressure measuring device, a wireless network, and an upper computer. A MCU control chip serves as a core of the blood pressure measuring device. An electromagnetic valve and an inflating pump are controlled to inflate and deflate a cuff, blood pressure signals input by a pressure sensor are acquired meanwhile and are internally operated by the MCU control chip, blood pressure data obtained by calculation is transmitted to the upper computer through the wireless network, and finally the data is stored, analyzed and displayed through the upper computer. The real-time wireless blood pressure monitoring system is simple to operate, convenient to carry and low in cost; meanwhile, a blood pressure judgment method applied to embedded system applications is achieved, and accuracy is high.

Description

Technical field [0001] The invention relates to a blood pressure monitoring system, a blood pressure measuring device and a blood pressure analysis method, in particular to a real-time wireless blood pressure monitoring system, a blood pressure measuring device and a blood pressure analysis method that can be used for monitoring quasi-critical patients. Background technique [0002] With the advancement of society, patients have higher and higher requirements for medical equipment and treatment equipment, and advanced monitoring equipment is only available in the intensive care unit of a few hospitals, and these equipment are large in size and complicated in connection. They are not suitable to be carried. While the staff causes work burdens, they also cause certain psychological pressure to patients. The wireless monitoring system can transmit physiological parameter signals such as blood pressure through the wireless network, reducing the complexity of connection between device...

AI Technical Summary

Problems solved by technology

At present, the mainstream blood pressure determination methods in the oscillometric method include the amplitude coefficient method, the waveform characteristic method, the improved amplitude coefficient method, and the coefficient difference ratio method. These methods have more or less shortcomings such as low accuracy and poor anti-interference ability.
