Diagnostic complex for measurement of the condition of biological tissues and liquids
First Claim
1. 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.

Abstract
Disclosed is 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. The assembly kit of the invention includes a main case; an aspirating needle adapted to be connected to the main case; a liquid collector adapted to be connected to said aspirating needle; and an electroimpedancemeter. The aspirating needle is used for obtaining a sample of biological liquid. The liquid collector receives said sample of said biological liquid and having a metal conductor in electrical contact with said needle and a metal piston. The electroimpedancemeter simultaneously measures electrical resistance of the sample at at least two different frequencies. Also disclosed is a method simultaneously obtaining a biological sample and measuring electrical impedance of the sample for the purpose of diagnosis of a condition of the sample. The method includes the steps of: contacting a biological tissue with an electrically conductive hook having a pointed end as a first electrode and a second electrode; measuring electrical impedance of the biological tissue contacted with the first and second electrodes at at least two different frequencies; and excising a part of the biological tissue with the pointed end of the hook to obtain a sample of the biological tissue.
