ABSTRACT:
In a device for measuring blood sedimentation rate automatically, a light-sensitive paper sheet is disposed so as to be movable relative to a blood sedimentation measuring tube, such as Westergren tube; a slit is provided between the light-sensitive paper and the measuring tube; and lamp means are provided on one side of the measuring tube opposite to the slit. Thus, the shade of the sedimented red blood corpuscles in the measuring tube formed as the light pulses from the lamp means passes through the measuring tube is projected on the light-sensitive paper through the slit with the feed of the paper and light pulses occurring in exact synchronism, and the rate of the blood sedimentation can be automatically recorded on the paper.
