Claim 0:
1. A pneumatic power pack, comprising:
a pressurized gas container storing pressurized gas;
a rupturer having a sharp end positioned adjacent the pressurized gas container;
a needle shield having a proximal end and a distal end;
a first rotator having a proximal end and a distal end, wherein the distal end of the needle shield is positioned adjacent the proximal end of the first rotator; and
a second rotator coupled with the first rotator and the gas container,
wherein, in response to the proximal end of the needle shield contacting an injection site, the first rotator is configured to move in a distal direction, and
wherein the movement of the first rotator in the distal direction causes a rotation of the second rotator which then drives the pressurized gas container towards the sharp end of the rupturer to thereby release the pressurized gas.
