Publication number: 20180272076Abstract: Exemplary embodiments provide automatic injection devices in which a shroud is automatically deployed to protectively sheath a needle after an injection is performed. Exemplary embodiments also provide shroud deployment assemblies including a shroud and a syringe carrier that, when cooperatively configured in an automatic injection device, ensure that the shroud is automatically and completely deployed after an injection is performed using the automatic injection device. Exemplary embodiments are also configured to ensure that, once the shroud is deployed to an extended position to sheath the needle, accidental forces applied to the shroud do not succeed in subsequently retracting the shroud to a retracted position in which the needle would become exposed.Type: ApplicationFiled: March 5, 2018Publication date: September 27, 2018Inventors: Vivek Rao, Sherwin Shang, Esra Ozdaryal, Eduard Tsvirko, Edwin Chim, David Post, Vincent DiPalma
