Abstract:
1. A biosensor cartridge for housing a plurality of biosensors, each biosensor of the plurality of biosensors having a reagent layer for detecting a specific component in a bodily fluid of a subject and an electrode for outputting an electric signal indicating that the reagent layer detects the specific component, said biosensor cartridge comprising: a cartridge body having a plurality of slits that are each shaped so as to conform to a front end of the biosensor, a rear end of the biosensor extending from the front end in a direction of insertion of the biosensor into a measuring device; wherein said plurality of slits are formed in said cartridge body so as to be parallel with each other such that the plurality of biosensors will be arranged in said slits so as to be parallel to each other and so as to extend perpendicularly from said cartridge body upward in the direction of insertion into the measuring device; wherein said plurality of slits are spaced at intervals such that an insertion slot of the measuring device for a target biosensor in one of said plurality of slits can cover the target biosensor and capture and pick up the target biosensor without touching biosensors in said plurality of slits adjacent to the target biosensor; wherein said cartridge body has a lid portion that covers an upper surface of said cartridge body; wherein said cartridge body has a hinge portion supporting a shaft of said lid portion so that said lid portion is rotatable at one end of said upper surface of said cartridge body; wherein said cartridge body is a rectangular parallelepiped in shape; wherein a pair of bearings that project outwardly in a longitudinal direction of said cartridge body from an end of said upper surface of said cartridge body, each of said bearings having an elongate bearing hole; wherein a pair of axial projections at an end of said lid portion engaged with said pair of bearings in said bearing hole thereof, said axial projections serving as fulcra upon rotation of said lid portion relative to said cartridge body; wherein a peripheral edge formed at the periphery of said upper surface of said cartridge body, said peripheral edge extending in a direction that is perpendicular to side walls of said cartridge body, and said peripheral edge having a plurality of notches therein; wherein reverse L-shaped projections that are formed on the periphery of an opening of said lid portion in the same plane as side walls of said lid portion and so as to be in positions that correspond to said plurality of notches, respectively, when said lid portion is rotated to cover said upper surface of said cartridge body; and wherein an elastic sealing member on an upper surface of said peripheral edge for sealing with said lid portion.
