Abstract
Patient monitoring system for the monitoring of a patient'"'"'s condition using monitoring parameters determined about the patient, said system comprising a central data processing unit (1), peripherals (2, 3, 4); parameter modules (5), each comprising a preamplifier (6) for preliminary amplification of a parameter signal, an A/D converter (7) for converting the parameter signal into digital form, and a first optic transmitter-receiver (8) for isolating the data transfer of the digital parameter signal; data transfer equipment for data communication between the first transmitter-receivers (8) of the parameter modules and the central data processing unit (1); a coupling frame (9), on which parameter modules (5) can be detachably mounted: parameter sensors (10) to be connected to the patient and a sensor cable (11) for each parameter sensor to pass the parameter signal from the parameter sensor to the preamplifier corresponding to the parameter concerned. The coupling frame (9) is made of a material substantially optically permeable to light to allow it to function as a medium for optic data communication. The data transfer equipment for communication between a first transmitter-receiver (8) and the central data processing unit (1) comprises a second optic transmitter-receiver (12) attached to the coupling frame (9) to achieve data communication together with the first transmitter-receivers using optic signals travelling inside the material of the coupling frame (9).
