Claim 1
Independent Claim
97 words
THE METHOD OF MEASURING BIOELECTRONIC PARAMETERS IN VIVO, COMPRISNG THE STEPS OF INSERTING A FIRST ELECTRODE INTO ACTUAL PHYSICAL CONTACT WITH BLOOD WITHIN A BLOOD VESSEL, COMPLETING AN ELECTRICAL CIRCUIT BETWEEN SAID FIRST ELECTRODE AND A SECOND ELECTRODE, PLACING SAID SECOND ELECTRODE IN ELECTRICALLY CONDUCTING RELATIONSHIP WITH SAID BLOOD BY DISPOSING AN ELECTROLYTE IN ACTUAL PHYSICAL CONTACT WITH BOTH SAID BODY AND SAID SECOND ELECTRODE, INSULATING SAID SECOND ELECTRODE FROM SAID BLOOD EXCEPT THROUGH SAID ELECTROLYTE, AND MEASURING THE POTENTIAL DIFFERENCE BETWEEN SAID FIRST AND SECOND ELECTRODES, WHEN THERE IS SUBSTANTIALLY NO CURRENT FLOWING IN SAID CIRCUIT.
