Diagnostic complex for measurement of the condition of biological tissues and liquids

摘要

Assembly kit for an apparatus and a method for simultaneously obtaining biological sample and measuring its electrical resistance at at least two different frequencies for diagnosis of sample condition. The apparatus includes a main case; an aspirating needle connected to main case for obtaining biological liquid sample; a liquid collector connected to aspirating needle for receiving biological liquid has a metal conductor in electrical contact with the needle and a metal piston; and an electro-impedance meter. The method includes the steps of contacting 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.
