Syrette

A syrette is a single-use device for injecting liquid through a needle.

[1] In WWII, the morphine syrette was included in first aid kits.

The wire loop was then removed and the needle was inserted under the skin at a shallow angle and the tube slowly squeezed from the sealed end (see subcutaneous injection).

[2] After injection the used tube was often pinned to the receiving soldier's collar to inform others of the dose administered.

[citation needed] Chemical treatment was subsequently distributed in autoinjector form.
