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.
Claims18
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.
A drug mixing and delivery 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;
- a first 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;
- a delivery assembly at least partially disposed in the housing;
- a second actuation device and whereupon activation causes the movable body to enter into a portion of the second chamber, creating a fluid communication between the second chamber and the delivery assembly and forcing the combined wet component and dry medicament through the delivery assembly.
