PROBLEM TO BE SOLVED: To provide a blood coagulation detection device that can detect coagulation of blood only by irradiating the blood stored in a container with light without mechanical operations on the container, thus reducing a time to detection.SOLUTION: A blood coagulation detection device 100 comprises: a light source 3 for irradiating measured blood BL stored in a blood collection tube (a container) 1 with light; a light receiver 5 for receiving the transmission light through the measured blood BL; an absorbancy calculation part 8 for calculating absorbancy over a predetermined wavelength region according to the received transmission light; and a coagulation detection part 9 for performing secondary differential on the absorbancy at the wavelength and detecting coagulation of the measured blood BL in the blood collection tube 1 according to the measured secondary differential absorbancy, which is a result of the secondary differential.SELECTED DRAWING: Figure 1 |
