BIOSENSOR CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To obtain a biosensor cartridge that eliminates the inflow possibility of a sample to the joint surface of a puncture instrument and a sensor chip to enhance a rate of success in measuring.

SOLUTION: In the biosensor cartridge 100 having a puncture instrument 31 keeping a puncture implement 11 protruded from its leading end part, the sensor chip 7 integrally attached to the puncture instrument 31 having a sample collecting port for sucking the sample opened in a close vicinity to the root 33 of the puncture implement 11 and a receiving member 35 for holding the sensor chip 7 along with the puncture instrument 31, a first protruded wall 47 for inhibiting the penetration of the sample is formed at a position covering the joint surface of the puncture instrument 31 with the sensor chip 7 in a protruded state.
