Patent ID: 7901931

Claim:
A device for measuring biological activities and/or physiological magnitudes comprising: a measuring cell ( 1 ) equipped with a chamber ( 2 ) that is suitable to receive cells to be analysed; and one or more probes ( 3 ) opening into the chamber ( 2 ), the probes ( 3 ) being connected to measuring resources ( 4 ) and resources for processing ( 5 ) electrical signals emitted by the probes ( 3 ); wherein the measuring cell ( 1 ) comprises a vertical well ( 8 ) of any cross section; wherein the vertical well ( 8 ) is open at its upper end and closed at its lower end, said lower end being made from polyvinyl chloride (PVC), and equipped on its lateral wall with holes ( 9 ) distributed uniformly around the well ( 8 ) so as to allow the probes ( 3 ) to open into the well ( 8 ), wherein said probes ( 3 ) are attached to the well ( 8 ) in a sealed manner, and are resting in support resources ( 12 ) distributed uniformly around the well ( 8 ), attached to the latter, and a removable cup ( 10 ) of cross section that is homothetic to the section of the well ( 8 ) and equipped on its lateral wall with holes ( 11 ) which lie opposite to the holes ( 9 ) of the well ( 8 ) when the cup ( 10 ) is positioned in the well ( 8 ) so as to allow the probes ( 3 ) to open into said cup ( 10 ) in which the micro-organisms to be analysed are placed, said cup being made from a metallic material that can be sterilised without damage.
