  • Monitoring the concentration of a substance or a group of substances in a body fluid
    Patent number: 6013029
    Abstract: The concentration of a substance or group of substances in a body fluid is monitored by means of an interface held in contact with a living human or animal body and a detector is positioned downstream from the interface. A profusion fluid is passed from the interface to and along the detector at a flow rate of less than 60 .mu.l/hour. A constant flow is maintained at the low flow rate with very little or no supply of energy, allowing for a compact construction and reduced measurement delay.
