Hypodermic needle (1844)

Rynd used a cannula and trocar. An incision is made by a lancet and the trocar inserted into the skin. The thin hollow tube, opened at both ends, is fitted over the top of the trocar. Once the cannula was inserted, the trocar was retracted and the medications or fluids placed into the cannula. Produced by John Weiss, surgical instrument maker.

On the 3rd of June a solution of fifteen grains of acetate of morphia, dissolved in one drachm of creosote, was introduced to the supra-orbital nerve, and along the course of the temporal,
malar, and buccal nerves, by four punctures of an instrument made for the purpose. In the space of a minute all pain (except that caused by the operation, which was very slight) had
ceased, and she slept better that night than she had for months.

Rynd’s description of the use of his syringe for the first time;

Nothing did me any good but a curious little new-fangled operation of putting opium under the skin, which relieved one for 24 hours

Florence Nightingale

Although Francis Rynd developed the first syringe with a hollow needle, he did not publicise until 1861 after Alexander Wood claimed to have invented the hypodermic syringe (1855)

The subcutaneous introduction of fluids, for the relief of neuralgia, was first practised in this  country by me, in  the Meath  Hospital, in the month of May, 1844. The cases were published  in the “Dublin Medical Press” of March 12, 1845. Since then, I have treated very many cases, and  used many kinds of fluids and solutions, with variable success

Rynd, 1861

The canula* (a) screws on the instrument at (b);  and  when  the button (c), which is connected to  the  needle (f), and acted on by a spring, is pushed up (as in Fig 2), the small catch (d) retains it in its place. The  point  of”  the  needle then projects a little beyond the canula (Fig. 2). The fluid to be applied is now to be  introduced into the canula through the hole (e), either from a common  writing-pen or the spoon-shaped  extremity of a silver director
