Abstract
A system for obtaining body fluids for continuous chemical analysis thereof includes a catheter for obtaining the material to be measured. The surface of the catheter is partially coated with a semi-permeable filter membrane. From the rear side of the filter membrane a plurality of channels are provided which communicate with a series of internal ducts which provide a fluid flow path for the material to be analyzed. The ducts are operatively coupled to a suction device pump and analyzing apparatus which are located remote from the catheter.
