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.

Claims

1. A medicant preparation device comprising:

a syringe barrel having a first end with an extension comprising a male fitting, a second end, and a longitudinal axis therebetween;

a piston insertable within the syringe barrel through the second end, the piston being slideable within the barrel;

a vial containing a first component of a medicant material;

an adapter component comprising;

a vial housing portion configured to reversibly receive the vial;

a piercing structure associated with the vial housing, the piercing structure having a head segment comprising a widest portion, a base portion having a first diameter, and a tube segment extending between the head segment and the base portion, the tube segment having a second diameter that is smaller than the first diameter and shorter than the widest portion of the head segment;

a port consisting of a female fitting configured to attach to the syringe at the male fitting at the first end of the syringe barrel;

a valve;

a first fluid passageway extending through the fitting to the valve; and

a second fluid passageway extending from the valve to the vial housing; and

flexible packaging configured to allow manipulation of the valve and sliding of the piston without opening of the package.

2. The device of claim 1 wherein the first and second passageways are orthogonal relative to each other.

3. The device of claim 1 wherein the adaptor component further comprises a third fluid passageway which extends from the valve, and wherein the valve is a three way valve.

4. The device of claim 1 wherein at least a portion of the packaging comprises a translucent material.

5. The device of claim 1 wherein the packaging comprises a removable portion, wherein prior to the removal of the removable portion at least one of the piston and valve are resistant to manipulation, and wherein removing the removable portion decreases the resistance to manipulation of at least one of the piston and the valve without exposing the syringe barrel, the piston or the adaptor component to an environment external to the packaging.

6. The device of claim 1 wherein the vial containing a first component of a medication agent is contained within the package.

7. The device of claim 6 wherein a second component of the medicant is provided within the syringe barrel.

8. The device of claim 1 wherein the vial having a septum is contained within the package, wherein the packaging allows manipulation of the vial position relative to the piercing structure, and wherein the piercing structure does not contact the septum prior to manipulation.
