Abstract
Embodiments described herein describe a drug delivery device. The device includes a medicament container, a compressed gas container, an outlet, and a double-sided needle located within the housing. When a user presses an actuation button, the compressed air container is moved towards the medicament container and towards a proximal end of the double-sided needle. The double-sided needle pierces both the compressed gas container and the medicament container, opening fluid flow communication between the two containers, and causing medicament to be expelled out of the medicament container.
