Syringe devices and methods for mixing and administering medication
First Claim
1. A medication agent preparation system comprising:
- a syringe comprising;
a syringe barrel having an internal chamber; and
a piston having a first end, a second end, and a fluid passageway passing longitudinally through the piston, at least a portion of the piston being inserted into the chamber, the portion comprising the first end;
a piercing structure associated with the second end of the piston, the piercing structure having a fluid channel and a tip;
a vial disposed proximate and movable relative to the tip of the piercing structure, the vial being disposed within an extension housing extending from the second end of the piston, the extension housing having a sidewall with longitudinal slots through the sidewall and having a plurality of ribs on an interior surface of the sidewall;
a first component of a medication agent disposed within the internal chamber;
a second component of the medication agent disposed within the vial; and
a valve associated with and orthogonally traversing the fluid passageway and disposed between the first end and the second end of the piston.

Abstract
The invention includes a device having a chamber within a syringe. A fluid passageway extends through a syringe piston. A valve is associated with the passageway controlling fluid passage through the piston. The invention includes a piercing structure having a head segment and a body portion, with a channel through the body portion and through at least one surface of the head without passing through the tip. In another aspect the invention encompasses a method of preparing an agent for administration to an individual. A first component is provided within a syringe and a second component is provided within a vial. A closed valve is associated with a fluid passageway between the vial and the syringe barrel through a piston. Valve repositioning allows fluid passage and sliding of the piston joins the first and second components. Repeated sliding of the piston mixes the components to produce the medication agent.
