PURPOSE:To make operation easy and to enable sure measurement by allowing the measuring person to recognize the lapse of a specified time by pilot lamps and sounding means simply by supporting blood settling bars vertically and operating switches for setting the settling time. CONSTITUTION:A blood settling bar 3 is supported to the 1st supporting part 4 for the settling bar. The operator operates a switch 8a to run a driving motor 11 in the case of measuring the settlement after 2hr. A pin 16a closes the contact 17a of the switch 8a, upon lapse of 2hr, to light a pilot lamp 9a and to trigger a sounding means 18. The operator is therefore capable of knowing distinctly the settlement with the bar 3 after 2hr. The operator operates a switch 8b in place of the switch 8a in the case of measuring the settlement after 1hr. The settlement with the bar 3 after 1hr from the point of the time when the settlement is started, can be distinctly known by a pilot lamp 9b and the means 18 in this case. Another blood settling bar 3 is supported in the 2nd and succeeding parts 4 and the settling speed thereof is known similarly as mentioned above. |
