Abstract

A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

Claims

1. A syringe device comprising:

a syringe barrel;

a piston having a first end insertable within the syringe barrel, and a second end opposing the first end;

a vial housing comprising a first part and a second part, the first part disposed within the piston and configured to receive a capped end of a vial in lengthwise orientation along a portion of the overall length of the piston, the second part configured to engage both a base of the vial and the first part, the second part further defining an appendage comprising a stem supporting a disk, the appendage configured to engage a syringe pump;

a fluid passageway extending through the piston from the first part through the first end;

a valve having a valve body having a longitudinal axis, the valve body extending through an opening in a side of the piston, the longitudinal axis orthogonally traversing the fluid passageway; and

a piercing structure associated with the second end of the piston and extending into the vial housing.

2. The syringe device of claim 1 wherein the second part is joinable to the first part.

3. The syringe device of claim 1 wherein the first part is attached permanently to the second end of the piston.

4. The syringe device of claim 1 wherein the first part is reversibly attached to the second end of the piston.
