An autoinjector is described that includes an outer body, a first trigger, an output needle, and a first compartment. The first compartment is positioned within the outer body and includes (i) a main body, (ii) a first biasing member coupled to the first trigger, and (iii) a protrusion positioned at a distal end of the main body. The autoinjector further includes a second compartment positioned in the outer body and in fluid communication with the first compartment and the output needle. The autoinjector also includes a second biasing member coupled to a second trigger. The first biasing member is configured to, upon application of force to the first trigger, automatically move an ampule in a distal direction relative to the main body to force the ampule against the protrusion, so as to break the ampule and allow a medicament to flow from the ampule to the second compartment.
