Abstract: Devices and methods for a compact injector are provided with a compact configuration for ease of carrying or storage, and an activated configuration ready for injection. In the compact configuration, a plunger and a needle are both retracted into the injector housing, and upon actuation to the activated configuration, the plunger extends proximally and the needle extends distally, ready for injection. An extendable needle shield is also provided to block visibility of the needle during injection, and to reduce the risk of inadvertent needle stick at other times, including disposal.

Abstract: An injection device uses telescoping and/or nested components and other features to make the overall device compact in size. The device is configured to have a storage position and an extended position, such that its needle is positioned within the housing of the device in a storage position, with the needle extending beyond the device housing when needed for an injection. The telescoping plunger mechanism has a storage position and an extended position for use. The device includes a needle depth cover, which extends from the device housing for use, and guides the user as to the correct depth for the needle to penetrate the user's skin. A switch allows different depth settings, for example allowing a deeper penetration for injection into a leg, and shallower penetration for injection into an arm.
