The Ludwig stromuhr (rheometer). The instrument, which consists of two glass bulbs, one being of known capacity, is connected with two cannulas fixed in the two ends of a severed artery and is so arranged that the bulb of known capacity can be repeatedly filled and refilled in succession. From the length of time it takes to fill the bulb a certain number of times, the flow through the artery is calculated. (From Foster M. A textbook of physiology. New York: MacMillan and Co., 1893:223.)
