ABSTRACT:
The invention relates to a method and apparatus for measuring one or more data of blood samples, such as oxygen saturation, contents of hemoglobin, bicarbonate, sodium, potassium, etc. involving hemolyzation of the blood sample. The blood sample is passed into a conduit and hemolyzed therein by imparting ultra-sonic waves to all parts defining said conduits. Measurement is performed after and possibly also prior to hemolyzation. In its preferred embodiment the apparatus according to the invention comprises a computer for automatically controlling the operational sequence of the components of the apparatus and for receiving measuring signals from measuring devices of the apparatus and converting said signals into immediately understandable digital data.
