Abstract

A sensor and a lancet are integrated with each other. A thin strip-shaped sensor and a lancet are integrated so that the lancet moves in parallel, along a longitudinal direction of the sensor. A measuring device to which an integrated lancet and sensor is attached is provided with a function of driving the attached lancet.

Claims

1-43. -43. (canceled)

44. A biosensor cartridge for housing plural biosensors, each having a reagent layer for detecting a specific component in bodily fluid of a subject, and an electrode for taking out an electric signal indicating that the reagent layer detects the specific component, wherein

a cartridge body has, at an end of its upper surface, a hinge for rotatably fixing a lid that covers the cartridge;

the cartridge body has plural slits for perpendicularly supporting the respective biosensors; and

the plural slits are formed in parallel with each other, from the upper surface toward the lower surface of the cartridge body, at regular intervals which allow an insertion slot of a measuring device for performing measurement using a target biosensor to be inserted without touching biosensors adjacent to the target biosensor.

45. A biosensor cartridge as defined in claim 44, wherein

the cartridge body to which the lid is attached is a rectangular parallelepiped in shape.

46. A biosensor cartridge as defined in claim 45, wherein

the lid is a hollow rectangular parallelepiped in shape, and has an opening at a portion opposed to the upper surface of the cartridge body.

47. A biosensor cartridge as defined in claim 44, wherein

the bottom of each slit has a shape that conforms to the shape of the front end of the biosensor.

48. A biosensor cartridge as defined in claim 47, wherein

the front end of the biosensor is semi-circular in shape.

49. A biosensor cartridge as defined in claim 44, wherein

the hinge is constituted by

a pair of bearings each having a side-to-side long bearing hole that projects outward along the longitudinal direction of the cartridge body from an end of the upper surface of the cartridge body, and

a pair of axial projections which are provided at an end of the lid, and serve as fulcra when being smooth-movably engaged with the bearings to rotate the lid;

a peripheral edge part is formed at the periphery of the upper surface of the cartridge body, which part extends in a direction perpendicular to the side walls of the cartridge body, and has plural notches;

reverse-L-shaped projections are formed on the same plane as the side walls of the lid, in positions corresponding to the notches of the peripheral edge part, at the periphery of the opening of the lid; and

a sealing member having elasticity is formed on the upper surface of the peripheral edge part.
