Glucose strip sensor and glucose measurement using the glucose strip sensor
First Claim
1. A glucose strip sensor comprising a non-conductive substrate, a lead section formed on the substrate, the lead section including leads and lead terminals, an electrode section formed on the lead section and provided at an upper surface thereof with a reaction layer, the electrode section including an operating electrode, a counter electrode, and a checking electrode, a resin plate adapted to define, over the electrode section, a space for receiving a blood sample, a cover formed on the resin plate, a sample introducing port adapted to introduce the blood sample into the space, and discharge ports adapted to vent air from the space, wherein:
- the electrode section further includes at least one is checking electrode adapted to check whether or not the blood sample is completely introduced in the space; and
the lead section further includes a lead and a lead terminal for the checking electrode.

Abstract
Disclosed is a disposable glucose strip sensor configured to rapidly and conveniently measure the concentration of glucose in blood and a glucose measurement method using the glucose strip sensor. In the glucose strip sensor, at least one checking electrodes are additionally provided at an electrode section including an operating electrode and a counter electrode. The checking electrode serves to check whether or not it is electrically connected with the counter electrode, upon measuring the concentration of glucose in a blood sample introduced in the sensor. Where two checking electrodes are provided, it may be checked whether or not an electrical connection is established between those checking electrodes. Based on the result of the checking, it is possible to determine whether or not a sufficient amount of blood sample is filled in the sensor. Accordingly, the measurement of glucose concentration can be accurately achieved.
