Abstract:
The present invention relates to a micro-dialysis probe for collecting substances of interest, e.g. ions or molecules, in particular from human or animal fluids or tissue. The micro-dialysis probe is of a kind having one or more flow channels carrying a perfusion fluid, the flow channel(s) being in contact with the tissue via one or more semi-permeable membranes. The substances of interest pass through the membrane(s) and are carried away by the perfusion fluid for further analysis. The micro-dialysis probe is formed as a probe system comprising a tube with at least one first conduit and one second conduit and a probe section, wherein one or more reinforcing fibres are positioned within said second conduit to reinforce the probe and to calibrate a return flow rate in the second conduit.

The micro-dialysis probe is of a kind having one or more flow channels carrying a perfusion fluid, the flow channel(s) being in contact with the tissue via one or more semi-permeable membranes. The substances of interest pass through the membrane(s) and are carried away by the perfusion liquid for further analysis. The micro-dialysis probe is formed as a probe system comprising a tube with at least one first conduit and one second conduit and a probe section, wherein a reinforcing tube with a third conduit is positioned within said second conduit.
Abstract:
The present invention relates to a system for analysing a fluid, and in particular for determining a content of a substance in the fluid. The system comprises an analysing unit and a substance collecting device, and a base unit comprising fluid reservoirs including a waste reservoir being pressurised.
