Abstract:
PROBLEM TO BE SOLVED: To monitor the glucose concentration level in the blood of a patient continuously or with short intervals by including in the optrode means an oxygen sensitive coating on at least one optical fiber at a portion where optical signals are produced to indicate the oxygen deflation as a result of the enzymatic reaction. SOLUTION: When the sensor is in use, an enzyme coating 40 on an optrode 22 starts an enzymatic reaction and generates catalysis of glucose in the presence of oxygen to produce gluconic acid and hydrogen peroxide. The enzymatic reaction proceeds with a stoichiometric excess of oxygen. An oxygen sensitive coating 42 on the enzyme optrode 22 fluoresces at an activity level, i.e., a light level in proportion to the oxygen depletion as a result of the enzymatic reaction. An oxygen decrease is substantially in proportion to glucose concentration level, hence the oxygen decrease measurement can be directly related to glucose concentration level. Thus a miniature optical device for easy in vivo implantation is obtained.
Abstract:
PURPOSE: To facilitate the removal of a sensor from a substrate, to prevent its breakage and reduce manufacturing period and cost by evacuating an insulat ed thin-film base layer using a thin-film layer of an adhesive, formed on the periphery of a substrate to adhere the base layer to the substrate and forming a thin-film sensor thereon. CONSTITUTION: A thin-film layer 30 of a curable adhesive is applied onto the periphery of a substrate 12 with a closed loop pattern, an insulated thin-film base 16 is placed thereon with adhering its edges to the layer 30, and they are heated and pressurized in a press in order to cure the adhesive. During this curing process, air and gas components are discharged from a cavity 32 to evacuate the central part of the base layer 16 and to adhere the base layer 16 to the flat upper surface of the substrate 12. After that, the base layer 16 is coated with a thin-film conductor layer, and an electrochemical sensor 10 is formed thereon by a photolithographic mask and the etching method. Since the sensor 10 physically adhers to the substrate 12 but does not bond directly, by cutting the surroundings of the sensor 10, it can be removed from the substrate 12 quickly and easily, to prevent breakage.

PURPOSE: To provide a sensor insertion set suitable for setting promptly and easily a sensor of a patient in the condition where the sensor electrode is in direct contact with blood, etc., of the patient. CONSTITUTION: The insertion set 10 has an insertion needle 14 which extends by penetrating an attachment base 34 attached on the patient's skin. A flexible thin-membrane sensor is supported by the attachment base 34, and has proximal part which forms a conductive contact electrically connected to a monitor 32 and distal part 16 protruding from the attachment base 34 and having a sensor electrode 18. The proximal part and distal part 16 of the sensor are offset linearly, and when the attachment base is thrust upon the patient's skin, the distal part 16 is interfitted inside the insertion needle 14 for percutaneous setting of the sensor using said insertion needle 14. Then, the insertion needle 14 is pulled out, and the sensor distal part 16 is left in the specified insertion position in the condition where the sensor electrode 18 is in contact with blood, etc., of the patient.
