Measuring system for determining the concentration of propofol (2,6 - diisopropylphenol) in the breath flow

摘要

A rapidly and compact executable measuring system for determining the concentration of propofol in the breath flow has the following features:a) a breathing gas conduit (1) has a the respiration be detected respiratory gas sensor (2).b) of the respiratory gas sensor (2) to an evaluation unit (3) is connected,c) with a with the breathing gas conduit (1) in the gas flow communication standing propofol sensor (5) with a downstream pump (6), whereind) of the propofol sensor (5) an electrochemical gas sensor with a measuring electrode of diamond-like carbon, ande) the evaluation unit (3) with the propofol sensor (5) and the pump (6) is connected, so thatf) in dependence on the signal of the respiratory gas sensor (2) the evaluation unit (3) the pump (6) for a respiratory gas - sampling is actuated and the propofol sensor (5) a measurement signal for the concentration of the propofol to the evaluation unit (3), which emits.
