Patent ID: 6859049

Claim:
An assembly kit for an apparatus for simultaneously obtaining a biological sample and measuring the electrical resistance of said sample at at least two different frequencies for diagnosis of a condition of said sample, comprising: a main case comprising a tube and demountable handle; an aspirating needle adapted to be connected to the main case at least partially inside said tube, for obtaining a sample of biological liquid and for serving as an active electrode in contact with said biological sample; a liquid collector adapted to be connected to said aspirating needle to receive said sample of said biological liquid, said liquid collector comprising a metal conductor in electrical contact with said needle and a metal piston, wherein at the determination of said condition of said biological liquid said needle executes the role of active electrode, and said metal piston executes the role of passive electrode; and an electroimpedancemeter adapted to be electrically connected to said active and passive electrodes, for simultaneous measurement of said electrical resistance of the sample at at least two different frequencies.
