Mechanical leech, Europe, 1850-1900

Bloodletting was a practice once carried out to treat a wide range of diseases and medical conditions. Baron Charles Louis Heurteloup (1793-1864) invented this device to replicate the blood-sucking action of leeches. As leeches were in great demand, this device may also have been an attempt to provide an alternative to the real thing. Heurteloup’s invention contains a small scarificator to pierce the skin and a suction pump to draw out the blood. The pump could hold a fluid ounce of blood, which is equivalent to 28.4 ml.
