Patent number: 9420966Abstract: A measuring system for measuring the concentration of substances or analytes in a body fluid or in a body tissue comprises a microdialysis probe comprising a microdialysis membrane, the probe being adapted to be placed in blood or in tissue, a flow through sensor for analyzing a fluid having passed the microdialysis probe, a pump for pumping the fluid to and through the microdialysis probe and further to and through the sensor, and tubing connecting the pump to the microdialysis probe and the microdialysis probe to the sensor. The pump effects a flow rate in the system in the interval 0.2-15 microliters per minute. The sensor comprises a flow channel having a flow resistance or pressure drop adapted to the characteristics of the microdialysis membrane so as to eliminate, or at least substantially reduce, ultra filtering in the microdialysis membrane.Type: GrantFiled: February 2, 2015Date of Patent: August 23, 2016Assignee: MAQUET CRITICAL CARE ABInventors: Stefan Lindgren, Anders Carlsson, Anton Karlsson, Henrik Falkén, Gerhard Jobst

Patent number: 9167997Abstract: The invention relates to a method and arrangement for continuously measuring substances in a pressurised body fluid. A probe (202) for enabling continuous measurement of the concentration of one or more substances in a pressurized body fluid is provided. The probe is adapted to be inserted into the pressurized body fluid, and comprises an interface and an outlet lumen. Furthermore, the probe is configured so that a continuous and spontaneous fluid flow is established from the body fluid through the interface to the outlet lumen. The fluid flow from the outlet may be analyzed by a sensor.Type: GrantFiled: November 16, 2010Date of Patent: October 27, 2015Assignee: Maquet Critical Care ABInventors: Anton Karlsson, Henrik Falkén, Gabriel Österdahl, Jan Liska
