The Microdialysis Catheter mimics a “blood capillary”. There is an exchange of substances
via extracellular fluid
The Microdialysis membrane
Chemical substances from the extracellular fluid diffuse through the dialysis membrane and
are carried out of the catheter by a flow of Perfusion Fluid to a microvial.
Clinical instrumentation Set up
Perfusion fluid is pumped from the Microdialysis Pump through the Microdialysis Catheter into
the Microvial. The sample is transferred to the Microdialysis Analyzer which shows the results
on a screen.
