Sensor chip, and measurement device and blood test device in which this sensor chip is used

摘要

This sensor chip (11) comprises a substrate (15) in the form of a flat board, a sample inlet (20) that is provided in the thickness direction of the substrate (15) and into which flows the blood (3) used for measurement, a supply path (21) that communicates with this sample inlet (20), and detection electrodes (17, 18, 19) provided to this supply path (21), wherein the substrate (15) is provided with a surplus blood reservoir (25) that draws in surplus blood (3a) and holds this drawn surplus blood (3a).

主权项

1. A sensor chip for analyzing the components of a biological sample, comprising:
a substrate in the form of a flat board; a sample inlet that is provided to one end of the substrate, into which flows the biological sample used for analysis; a supply path that communicates with the sample inlet and into which the biological sample is introduced; detection electrodes that are provided to the supply path and detect signals used for analysis; and a surplus blood reservoir that is provided to the substrate and into which extra blood not used for analysis is drawn and held, wherein the substrate has a surplus blood inlet that is provided to an end of the substrate and communicates with the surplus blood reservoir, and the surplus blood inlet draws the surplus blood into the surplus blood reservoir by capillary action.
