Abstract:
Microdialysis system comprisinga microdialysis probe (12) that can be inserted in organic tissue (10) and has a dialysis membrane (28) to separate a probe channel (18) from the tissue (10), a sensor cell (14) for the detection of components in the perfusion fluid that is conveyed from the microdialysis probe (12) and a transport device (16) to convey a perfusion fluid through the probe channel (18) of the microdialysis probe (12) to the sensor cell (14), characterized in that the transport device (16) has a pressure pump unit (30) connected on a pressure side to an inlet (20) of the probe channel (18) and a suction pump unit (31) having a suction side and being connected on the suction side to an outlet (24) of the probe channel (18) the suction pump unit operating simultaneously with the pressure pump unit (30).
