(Hämodromograph nach Chauveau und Lortet.)
Description: This, as No. 275, is a device for measuring blood
flow velocity, through the use of a pendulum which reflects,
through the length of the swing, the blood velocity. While the
word "hemodrometer" is considered archaic, it can still be found
in medical dictionaries. A pipe through which blood is conducted
from a blood vessel contains a lightweight aluminum needle, which
is deflected more when there is a higher blood velocity. The
device also provides a scored circular rule on which the blood
velocity can be read. (Expanded caption Copyright 1998, Edward J.
