Electrochemical detection device
First Claim
1. An electrochemical detection device comprising as one piece, a cell unit and a supporter;
- said cell unit comprising a cell block, gasket and working electrode, wherein said cell block contains a test solution introduction means and a test solution outlet means having a test solution outlet route both being substantially normal to the working electrode, through which the test solution flows following introduction thereof into the cell block, and reference and counter electrodes adapted to be in contact with said test solution after introduction thereof, said gasket containing an opening defining the cell which communicates with the test solution introduction and outlet means and communicating with the working electrode;
said supporter containing a pressure means adapted to push the working electrode first against the gasket and then onto the cell block, and also adapted to retract the working electrode from the cell block, wherein said pressure means comprises a ball, a spring inside a sleeve horizontally disposed within said supporter, and an electrode-pushing plate disposed between the ball and the working electrode whereby upon movement of the ball, the electrode-pushing plate comes into contact with said working electrode.

Abstract
An electrochemical detection device comprising a cell unit that has a cell therein and a supporter that rotatably supports said cell unit and that is made in one piece with said cell unit, wherein said cell unit has a cell block that has a test solution introduction route through which a test solution flows after being introduced into the inside of said cell block and that has a test solution outlet route through which the test solution leaves the inside and that has a reference electrode and a counter electrode provided so that they come into contact with the test solution flowing from said test solution introduction route to said test solution outlet route; a gasket that has an opening constituting said cell, and that is in contact with said cell block so that said opening is connected with both the test solution introduction route and the test solution outlet route; a working electrode that faces said opening of the gasket, and said supporter has a pressure means that pushes said working electrode onto said cell block by means of said gasket while said supporter and said cell unit are being incorporated into one piece, which removes the pressure from said pressure means.
