Syringe Devices, Components of Syringe Devices, and Methods of Forming Components and Syringe Devices

A syringe device comprising:

• a syringe barrel;
• a syringe piston having a first end insertable within the syringe barrel, and a second end opposing the first end;
• a vial housing associated with and extending from the second end of the piston;
• and
• a piercing structure associated with the second end of the piston and extending into the vial housing.

A syringe device comprising:

• a syringe barrel;
• a piston sleeve;
• a sleeve insert having a first end insertable within the sleeve, an opposing second end, and a length defined by the distance between the first and second ends;
• a fluid channel extending along an exterior side of the sleeve insert from the first end at least a portion of the length of the sleeve insert;
• and
• a rotary valve controlling fluid communication between the fluid channel and the syringe barrel.

A syringe device comprising:

• a syringe barrel;
• a piston sleeve;
• a sleeve insert having a first end insertable within the sleeve, an opposing second end, and a length defined by the distance between the first and second ends;
• a compartment disposed within the sleeve insert;
• and
• a valve controlling fluid communication between the compartment and the syringe barrel.

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 comprising the first end being inserted within the chamber;
• and
• a valve associated with the fluid passageway, the valve comprising a valve body and a cap over-molded onto the valve body.

A method of preparing a medication agent for administration to an individual, comprising:

• providing a syringe comprising a syringe barrel and a piston disposed at an initial position relative to the syringe barrel, the piston comprising a piston sleeve and a sleeve insert;
• providing a first component within the syringe barrel;
• providing a second component within a vial;
• providing a valve associated with a fluid passageway between the vial and the syringe barrel, the valve being initially provided in a closed position, blocking fluid passage through the passageway;
• repositioning the valve;
• sliding the piston to join the first component with the second component;
• mixing the first and second component to form a medication agent;
• and
• drawing the medication agent into the syringe barrel.

A method of preparing a composition comprising;

• providing a syringe barrel having a barrel chamber containing a first component;
• providing a piston having a compartment containing a second component, the piston comprising:
• a piston sleeve;
• a sleeve insert comprising a tip and a body;
• and
• a seal over-molded onto the tip and an end of the piston sleeve, the seal having at least one opening passing therethrough;
• rotating the piston sleeve relative to the insert to establish fluid communication between the compartment and the barrel chamber;
• sliding the piston to join the first and second components;
• mixing the first and second components to form a composition;
• and
• drawing the composition into the syringe chamber.
