Abstract
An injection device () includes a lower housing (), a sleeve () supported by the lower housing, and a syringe spring () received within the sleeve. The spring supports a syringe (). A needle guard () is proximally slidable relative to the lower housing from a first position, concealing the syringe needle (), to a second position. A needle guard spring () biases the needle guard distally relative to the lower housing. An upper housing () is distally slidable relative to the lower housing from a pre-use position to a dispensed position. Movement of the needle guard from the first position to the second position extends the distal tip of the needle distally beyond the needle guard by a first distance. Subsequent distal movement of the upper housing relative to the lower housing from the pre-use position toward the dispensed position advances the distal tip of the needle distally further beyond the needle guard by a second distance.
