BIOSENSOR CARTRIDGE

摘要

To provide a biosensor cartridge in which burden on a user can be lessened by decreasing the quantity of a sample required for measurement, and the sample at the puncture mouth can be sampled easily without requiring an operation for making a sampling mouth approach the puncture mouth. When one end of a biosensor chip (11) is pressed against a specimen, an elastic body (20) is compressed to allows a puncture tool to project (12) and the specimen can be punctured. When the pressing force is weakened, the puncture tool (12) is drawn out from the specimen by the restoring force of the elastic body (20) and a sample flows out from the puncture mouth. Since the puncture mouth and a sampling mouth (13) provided in the biosensor chip (11) are included in an enclosed half-open space (23) formed by the elastic body (20), even a small quantity of sample can be sampled easily. Furthermore, since a protrusion (19) provided on one member is fitted in a recess (26) provided in the other member at the joint between the elastic body (20) and the biosensor chip (11), the elastic body (20) can be fixed surely to a predetermined position of the biosensor chip (11).
