Patent ID: 8778152

Claim:
A biomaterial measuring sensor used with a detector to measure a biomaterial, comprising: a body portion having a recess for holding an end of a detector and a cavity vertically passing through the body portion at the bottom of the recess, wherein the cavity includes a reaction chamber at upper portion thereof, a capillary tube connected to the reaction chamber under the reaction chamber and having a width smaller than the width of the reaction chamber, and a biomaterial introduction hole connected to the capillary tube under the capillary tube, and wherein the body portion is configured to be attached to and detached from the detector; and a sensor portion having a reactive electrode on a lower surface, a reaction reagent fixed onto the reactive electrode and biochemically reacting with the biomaterial, a conductive electrode configured to transmit a signal generated by the biochemical reaction to the detector and positioned on an upper surface which is the opposite surface to the lower surface, and a conductor passing through the sensor portion and electrically connecting the reactive electrode to the conductive electrode, wherein the sensor portion is positioned on the bottom of the recess to cover the reaction chamber and attached to the body portion such that the reactive electrode and the reaction reagent are positioned over and faces the reaction chamber and the capillary tube, and the conductive electrode is exposed to the recess.
