== History ==
Automatic syringes are known since  the 1910s,<ref>{{patent|GB|143084A|Improvements in and relating to self-acting syringes for hypodermic injections}}</ref> and many spring-loaded devices with needle protectors were patented in the first half of the 20th century,<ref>{{Cite web|url=https://worldwide.espacenet.com/patent/search?q=cl%20%3D%20%22A61M5%2F2033%22%20AND%20pd%20%3C%20%221950-01-01%22|title = Espacenet – search results}}</ref> but it was not until 1970s when they became economically feasible to mass-produce (simple [[syrette]]s were used instead before). In 2023 an [[Open-source hardware|open source]] autoinjector was developed that could be digitally replicated with a low cost desktop [[3D printing|3D printer]].<ref name=":0">{{Cite journal |last1=Selvaraj |first1=Anjutha |last2=Kulkarni |first2=Apoorv |last3=Pearce |first3=J.
