Abstract
An auto-injector for rapid delivery of a bolus of injectable medication has a generally flat, sealed housing with small peripheral dimensions, approximating those of a credit card. A syringe, configured to be contained within the flat housing is pre-filled with the medication. The housing contains a mechanism that, when triggered, automatically drives the syringe and needle forwardly to an injection position and then continues to compress the volume of the syringe to effect rapid injection. The forward injection end of the device includes an actuator that also conceals and protects the needle at all times and, prevents post-injection hazards. The flat faces of the device have graphic symbols and other visual indicia relating to the operation and condition of the device. The device enables a simple three-step operation that reduces the risk of improper use.
