Measurement system to measure a physiological condition in a body

摘要

Measurement system comprising a sensor wire provided, at its distal end, with a physiological condition sensor to measure a physiological condition inside a patient, and to provide measured data to an external device, the measurement system comprises a transceiver unit adapted to be connected to the proximal end of the sensor wire, and a communication unit arranged in connection with the external device. The transceiver unit is adapted to communicate, by a communication signal, with the communication unit, in order to transfer measured data to the external device. The communication signal, including the measured data, is generated by the transceiver unit and transferred as an output signal and the communication unit is arranged to be connected to a standard input/output connector of the external device and to communicate with the external device in accordance with an established standard, or in accordance with relevant parts of an established standard, e.g. BP22 or USB. The measurement system further comprises a physical optical communication link arranged between the transceiver unit and the communication unit, wherein the communication signal is an optical signal transferred by the optical communication link. The transceiver unit also comprises an energy means adapted to energize the sensor, the transceiver unit and also the optical communication link.
