Abstract
An electrocatalytic sensor in catheter type of construction for determining glucose in body fluids, especially in the blood, having the following features: PA1 a tubular body made of bio-compatible material that is subdivided into three sections, PA1 a sleeve-shaped reference electrode arranged between the first and the second, or between the second and the third section of the tubular body, PA1 a sleeve-shaped working electrode arranged--correspondingly--between the second and the third, or between the first and the second section of the tubular body, said working electrode having a slit extending in longitudinal direction over the full length, PA1 a hydrophilic membrane stretched over the working electrode whose ends are guided through the slit into the interior of the electrode and which is held in the slit by a wedge made of bio-compatible material, PA1 a counter-electrode which seals the one end of the tubular body, and PA1 lead wires to the electrodes arranged within the tubular body which are brought to the outside through the other end of the tubular body.
