Abstract

Injector devices and methods for their operation for containers having an opening with or for an injection needle. The container is optionally of syringe type with a barrel of substantially constant axial cross-section. In one embodiment, the devices include a penetration arrangement operable to move the needle from a rear position to a forward position, an injection arrangement operable at least to expel container content through the needle, and a transmission and a switch system allowing manual energy applied to the device to manually operate the penetration arrangement and then manually operate the injection arrangement.
