摘要： This invention provides a method and a device for detecting occlusion and/or reopening of an artery of a body caused by a changing pressure applied on the artery as well as a system for measuring the systolic blood pressure of an artery of a body. The method comprises the steps of: obtaining a blood flow signal indicative of a change of the blood flow in the artery caused by the changing pressure,using a Doppler Ultrasound transducer attached to the exterior of the body; deriving, from the blood flow signal, at least one variable of a first variable indicative of the magnitude of the blood flow and a second variable indicative of the periodicity of the blood flow; and detecting the occlusion and/or reopening of the artery on the basis of the at least one variable. In this way, the occlusion/reopening of the artery can be detected automatically. Since the need to manually detect the occlusion and reopening of the artery by listening with a stethoscope or a Doppler probe is eliminated, the detecting result is more predictable and repeatable, and therefore also more accurate.

摘要： The method of determining the open/closed switch moment of an artery of interest under a changing pressure comprises: detecting a first Doppler ultrasound signal from the blood flow in the artery of interest using a first Doppler ultrasound transducer, which is placed on the artery of interest in one limb which is provided with a cuff that is capable of being inflated or deflated to provide the changing pressure to the artery of interest; detecting a second Doppler ultrasound signal from the blood flow in a reference artery using a second Doppler ultrasound transducer, the reference artery being in any one of the other three limbs; deriving a third signal from the first Doppler ultrasound signal and the second Doppler ultrasound signal, the third signal indicating the degree of synchronism between the first Doppler ultrasound signal and the second Doppler ultrasound signal; and out- putting a fourth signal to indicate the artery of interest is closed or reopened at the moment when the third signal satisfies a predefined condition. By utilizing the second ultrasound signal as a reference and deriving a signal indicating the synchronization property between the two ultrasound signals, the open/closed status of the artery of interest under a changing pressure can be determined more stably and more reliably regardless of the detailed condition of the patient.

摘要： The method of positioning a Doppler ultrasound transducer for performing blood flow measurement according to the invention comprises the steps of: detecting a pressure oscillation signal from an inflated cuff placed on patient's artery; detecting an ultrasound pulse signal from the Doppler ultrasound transducer placed along the artery; deriving a first signal from the pressure oscillation signal and the ultrasound pulse signal, the first signal indicating the degree of synchronization between the pressure oscillation signal and the ultrasound pulse signal; and outputting an indication signal to indicate the Doppler ultrasound transducer is in a desired position when the first signal satisfies a predefined condition. Since the synchronization property of the cuff pressure oscillation signal and the ultrasound signal caused by the blood flow is utilized to determine whether the transducer is well positioned or not, ultrasound signal, which is a pulse signal but not reflecting the blood flow of the artery, could be determined as not in synchronization with the oscillation signal and therefore the accuracy of the positioning could be improved.
摘要翻译：根据本发明的定位用于执行血流测量的多普勒超声换能器的方法包括以下步骤：从放置在患者动脉上的充气袖带检测压力振荡信号; 检测来自沿着动脉放置的多普勒超声换能器的超声脉冲信号; 从所述压力振荡信号和所述超声脉冲信号中导出第一信号，所述第一信号指示所述压力振荡信号与所述超声脉冲信号之间的同步度; 并且当所述第一信号满足预定条件时，输出指示多普勒超声换能器的指示信号处于期望位置。由于袖带压力振荡信号与由血流引起的超声波信号的同步性被利用来确定换能器是否良好定位，作为脉冲信号而不反映动脉血流的超声波信号，可以确定为不与振荡信号同步，因此可以提高定位的精度。
