About Charles Pravaz
- Charles Gabriel Pravaz (24 March 1791 – 24 June 1853) was a French orthopedic surgeon and inventor of the hypodermic syringe.
- While the concept dated to Galen, the modern syringe is thought to have originated in 15th-century Italy, although it took several centuries for the device to be developed.
- In 1657, experiments were conducted on syringe-like devices by Englishmen Christopher Wren and Robert Boyle, while French physician Dominique Anel created the modern pump syringe as a device to clean wounds using suction.In all these cases, it was impossible to perform injections without an incision until Irish physician Francis Rynd invented the hollow needle in 1844.
- Wanting to inject iron perchloride coagulant into an aneurysm, Pravaz adapted Rynd's needle, rather than using the usual suction tube.
- Measuring 3 cm (1.18 in) long and 5 mm (0.2 in) in diameter, the syringe was entirely in silver, made by Établissements Charrière, and operated by a screw (rather than the plunger familiar today) to control the amount of substance injected. Pravaz did little development of the invention, and it would be another French surgeon, L.
- J.
- Béhier, who would make Pravaz's invention known across Europe.
- It thus initiated the science of sclerotherapy and the treatment of varicose veins and other varices.
