Francis Rynd (1801 – 1861) was an Irish physician.
Arguably the inventor of the hypodermic needle, performing and recording the results of the first hypodermic injection on June 3rd 1844. However, the invention is more commonly attributed to Alexander Wood in 1853
In Rynd’s design, a morphine solution flowed under gravity through the skin breaching trochar, acting as a sedative to treat neuralgia. The 1853 invention used a plunger syringe, allowing doctors to inject solutions faster, and to give intravenous injections.
Nothing did me any good but a curious little new-fangled operation of putting opium under the skin, which relieved one for 24 hours
