1. A drug mixing system comprising:
- a housing comprising a fluid channel disposed between a first and second chamber, wherein a dry medicament is initially in direct contact with the fluid channel, and wherein the first chamber is configured to store a wet component;
a movable body disposed between the first and second chambers;
an actuation device configured to cause a portion of the movable body to enter a portion of the first and second chambers, creating fluid communication between the fluid channel and the first and second chambers, thereby forcing a portion of the wet component from the first chamber through the fluid channel into the second chamber.

Abstract
A portable auto-injector is capable of moving from a compact state where the auto-injector is in a shape easier to transport than in an activation state wherein the auto-injector has been extended. A safety limits movement of the needle assembly and prevents premature needle sticks. The drug is stored in one or more dry and wet medicament states until need.
