Illustration of Rynd's hypodermic needle shown at F of Fig. 1. In a 12 March 1845 article in the Dublin Medical Press, Rynd outlined how he had injected painkillers into a patient with a hypodermic syringe in on 3 June 1844: [6] [7]
In 1853, wanting to inject iron perchloride coagulant into an aneurysm, Pravaz adapted Rynd's needle, [3] rather than using the usual suction tube. Measuring 3 cm (1.18 in) long and 5 mm (0.2 in) in diameter, his syringe was entirely in silver, [ 2 ] made by Établissements Charrière , and operated by a screw (rather than the plunger familiar ...
