Abstract

Automatic injection devices (i.e., auto-injectors) and methods are disclosed that use gas-generating chemical reactions for parenteral delivery of therapeutic fluids. The generated gas may place the auto-injector in a punctured configuration to puncture a patient's skin with a needle, an injected configuration to deliver the therapeutic fluid through the needle and into the puncture site, and/or a retracted configuration to withdraw the needle from the puncture site.
