Embodiment Construction

[0027] Embodiments of the present invention will be described below with reference to the drawings. Blood analyzers, such as figure 1 As shown, it is composed of a measuring instrument main body 1 and a substrate 2. The substrate 2 is in the shape of a plate, which can be properly inserted into the measuring instrument main body 1 and discarded after use.

[0028] In the embodiment of the present invention, the substrate 2 can also be used in a measuring instrument having an existing basic configuration. Substrate 2 as figure 2 with image 3 As shown, the whole is in the shape of a rectangular plate, an enzyme electrode 10 is formed at the front end of one surface, and two lead terminals 13 and 14 are formed at the bottom. These lead terminals 13, 14 are preferably made of silver. The enzyme electrode 10 is formed by superimposing the reaction layer 5 on the electrode part 4, and the electrode part 4 is composed of a carbon working terminal 11 and a carbon counter termina...

Abstract

A blood measuring instrument is provided for measuring a specific component of blood. The instrument includes a plate-like chip (2) for sucking sampled blood and a main detecting unit (1) provided with a connector (3) into which the chip (2) is plugged. The chip (2) has, on its one side, an enzyme electrode section for passing a response current upon reaction with a specific component of the blood, and lead terminals connected to the enzyme electrode section. The main detecting unit (1) has, within the connector, two sets of connection terminals (21,22) engageable with the lead terminals on the chip (2). These two sets of the connection terminals (21,22) are held in facing relation to each other. It is possible to insert the chip (2) into the connector (3) of the main detecting unit (1) whether one surface of the chip faces upward or downward. The lead terminals of the chip are properly connected to either one of the two sets of the connection terminals (21, 22) facing each other in the connector, thereby enabling desired measurement.

Description

technical field [0001] The invention relates to an instrument for measuring the concentration of specific components contained in blood, especially a blood measuring instrument for measuring the concentration of glucose in blood. Background technique [0002] In recent years, various biosensors have been developed using the catalytic action unique to enzymes, and have been tried in various clinical fields. Especially in the treatment of diabetes, it is indispensable to keep the glucose concentration in the patient's blood (hereinafter referred to as the blood sugar level) normal, so the utilization value of the biosensor is very great. For hospitalized patients, maintaining normal blood sugar can be carried out under the supervision of a doctor; for outpatients, since the doctor cannot directly supervise, it is up to the patient to control blood sugar by himself, then self-management is a kind of important treatment. [0003] Methods for self-management of blood sugar incl...
