    • The present invention relates to an eavesdropping device for monitoring measured physiological variables of an individual, which eavesdropping device comprises a receiver and a communication interface. The eavesdropping device of the present invention is typically applied in a system comprising a first sensor arranged to be disposed in or outside the body of the individual for measuring aortic blood pressure Pa, and a second sensor arranged for measuring distal blood pressure Pd. Further, the system comprises a central monitoring device for monitoring the measured physiological variables and a communication link between the sensors and the central monitoring device for communicating signals representing the measured physiological variables from the sensors to the central monitoring device. The eavesdropping device is configured such that the communication interface is arranged at the communication link to communicate at least the signal representing the aortic blood pressure to a monitor of the eavesdropping device. Moreover, the receiver of the eavesdropping device is connected to the communication link, in parallel with the central monitoring device. The signal representing the aortic blood pressure Pa is communicated to the receiver via a high-impedance connection at the communication interface, and the receiver of the eavesdropping device is further arranged to receive the signal representing the measured distal blood pressure P d from the communication link. By means of the blood pressure signals of the respective sensor, FFR can be calculated.
    • 本发明涉及一种用于监测个人的测量生理变量的窃听装置,该窃听装置包括接收机和通信接口。 本发明的窃听装置通常应用于包括布置成设置在个体体内或外部的用于测量主动脉血压Pa的第一传感器和布置成用于测量远端血压Pd的第二传感器的系统。 此外,该系统包括用于监测所测量的生理变量的中央监控装置以及传感器与中央监测装置之间的通信链路,用于将表示所测量的生理变量的信号传递到中央监测装置。 窃听设备被配置为使得通信接口被布置在通信链路处,以将至少表示主动脉血压的信号传送到窃听设备的监视器。 此外,窃听设备的接收机与中央监控设备并行连接到通信链路。 代表主动脉血压Pa的信号通过通信接口处的高阻抗连接传送给接收机,并且窃听设备的接收机进一步布置成从通信链路接收表示测量的远端血压Pd的信号。 通过各传感器的血压信号,可以计算FFR。
