DEVICE FOR ACQUIRING PHYSIOLOGICAL VARIABLES MEASURED IN A BODY

摘要

An eavesdropping arrangement for acquiring a measured physiological variable of an individual includes a receiver and a communication interface in a housing separate from the receiver. The communication interface is positioned along a communication link between a first sensor, which is configured to measure aortic blood pressure and to provide a signal representing measured aortic blood pressure, and a central monitoring device configured to monitor the measured aortic blood pressure. The communication interface includes a connection to the communication link that permits the communication interface to eavesdrop on the signal representing measured aortic blood pressure such that information representing measured aortic blood pressure is sent to the receiver while allowing the central monitoring device to receive and use the signal representing measured aortic blood pressure.

1. A system comprising:
a distal pressure sensor configured to measure distal blood pressure of an individual and to provide a signal representing a measured distal blood pressure value; a receiver configured to receive both (i) a signal representing a measured aortic blood pressure value measured by an aortic pressure sensor, and (ii) a signal representing the measured distal blood pressure value, the receiver comprising a display configured to display data that is based on at least the measured aortic blood pressure value and the measured distal blood pressure value; a communication interface configured to (i) receive a signal representing the measured aortic blood pressure value from the aortic pressure sensor via a wired connection between the aortic pressure sensor and the communication interface, (ii) provide a signal representing the measured aortic blood pressure value to a monitoring device via a wired connection between the communication interface and the monitoring device without substantially changing the measured aortic blood pressure value, and (iii) send a signal representing the measured aortic blood pressure value to the receiver via a wireless connection between the communication interface and the receiver.
