Arterial blood pressure measuring device based on ultrasonic blood flow information

Abstract

The invention relates to an arterial blood pressure measuring device comprising an electrocardiosignal collecting module, a blood flow speed signal collecting module, a signal preprocessing module and a microprocessor module, wherein the electrocardiosignal collecting module is used for collecting the electrocardiosignals of human bodies; the blood flow speed signal collecting module is used for collecting the blood flow speed signals of the human bodies; the signal preprocessing module is electrically connected with the electrocardiosignal collecting module and the blood flow speed signal collecting module and is used for preprocessing the signals coming from the electrocardiosignal collecting module and the blood flow speed signal collecting module; and the microprocessor module is electrically connected with the signal preprocessing module and is used for receiving the signals processed by the signal preprocessing module and calculating blood pressure according to a stored blood pressure measuring equation and the signals coming from the signal preprocessing module to obtain a blood pressure measuring result. The arterial blood pressure measuring device continuously collects and obtains the electrocardiosignals and the blood flow speed signals through the electrocardiosignal collecting module and the blood flow speed signal collecting module and obtains the blood pressure measuring result according to the signals and the blood pressure measuring equation to realize continuous blood pressure measurement.

Description

【Technical field】 [0001] The invention relates to the field of blood pressure measurement, in particular to an arterial blood pressure measurement device. 【Background technique】 [0002] Measuring blood pressure is a basic method for understanding health conditions and observing conditions, especially for middle-aged and elderly people suffering from cardiovascular diseases. Hypertension is a direct cause of many high-risk cardiovascular diseases. The study found a significant correlation between the rate of change in blood pressure and mortality from cardiovascular disease. Therefore, grasping the rate of change of blood pressure through continuous blood pressure monitoring and taking corresponding measures will greatly reduce the fatal danger of hypertensive patients. At present, technologies that can be used for continuous blood pressure measurement on wearable devices mainly include the following three. [0003] The first technique determines the arterial blood pressu...

Problems solved by technology

This technique is still in the research stage, and the following problems have yet to be resolved in practice: first, the relationship between pressure and blood volume change is not static, and it may change with time and physiological state changes; Secondly, the change in pulse blood volume is not entirely caused by the change in blood pressure; finally, the transcutaneous pressure-blood volume change curve is not static, and there is a hysteresis phenomenon
