System for processing patient monitoring power and data signals

摘要

A device interface selectively acquires patient physiological parameter data. An acquisition processor acquires physiological data from a patient. A communication processor is coupled to an optical communication pathway for receiving optical signals from a source. A conversion processor electrically coupled to the acquisition processor and communication processor converts a first optical power signal at a first frequency and received via the optical communication pathway using the communication processor, to a first electrical signal for providing power to the device interface. The conversion processor converts an optical control signal at a second frequency different from the first frequency and received via the optical communication pathway using the communication processor, to a second electrical signal for providing control data to the acquisition processor directing the acquisition processor to acquire at least one physiological parameter from a patient.
