STRUCTURE AND METHOD FOR CALIBRATION FOR CALIBRATING BLOOD COMPONENT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce more measurement errors of a blood component measuring device by calibrating with a structure for calibration and to improve its measurement accuracy.

SOLUTION: The structure 10 for calibration includes a body part 24 having a light scatterer 22 therein and a flow cell 28 filled with a calibration liquid 26. The flow cell 28 comprises a transmitter 40 to transmit a near-infrared light irradiated from a light emission part 18 of the blood component measuring device 12 and a tube 42 to be connected to the transmitter 40. A transmission part includes a first transmission part 44 with a short optical path length of the near-infrared light and a second transmission part 46 with a long optical path length of the near-infrared light to be connected to the first transmission part 44, which switches a position of the transmitter 40 to the light emission part 18 by sliding displacement of the structure for calibration 10.
