Abstract

A syringe device having a syringe barrel and a syringe piston having a container housing. At least a portion of the container housing is insertable within an internal chamber of the syringe barrel. A fluid passageway extends from the container housing through a piston stem. A method of protecting a syringe handler including providing the components of a syringe device and encasing the components in a protective film. The protective film is loose to allow manipulation of the syringe components relative to one another without opening or puncturing the film. Protective syringe device packaging that includes a laminate film of material sealed to encase the components of a syringe device containing a potentially harmful agent.

Claims

1. A syringe device mixing/administration system comprising:

a syringe barrel having a forward end and an opposing back end, the forward end configured to both removeably couple with a fluid-bag and expel fluid from the interior of the barrel, the opposing back end defining an interior circumference and configured to receive a syringe piston;

a syringe piston insertable into the back end of the syringe barrel, the syringe piston defining a conduit extending the length thereof;

a vial housing extending from an end of the piston, the vial housing having sidewalls defining an exterior circumference less than that of the barrel and insertable into the barrel, the vial housing an access window in the sidewall of sufficient size to allow removal of the lid while a vial is within the housing;

at least one vial;

a fluid-bag reversibly attachable to the forward end of the syringe barrel; and

a protective film material encasing the syringe barrel, syringe piston, vial housing, vial, and fluid-bag, the protective film material configured to encase the syringe barrel, syringe piston, vial housing, vial, and fluid-bag while the fluid is expelled from the barrel of the syringe and into the fluid-bag.

2. The system of claim 1 further comprising a protective tray containing the protective film encasing the syringe barrel, syringe piston and fluid-bag, the protective tray comprising raised protrusions to support the syringe barrel and the syringe piston.

3. The system of claim 1 wherein the protective film is configured to allow manipulation of the syringe piston relative to the syringe barrel without removal or puncturing the protective film.

4. The system of claim 1 wherein the protective film provides protection to handlers from the contents of the syringe and the bag.

5. The system of claim 1 wherein the piston comprises a fluid passageway passing longitudinally through the stem.

6. The system of claim 1 further comprising a valve device disposed between the fluid-bag and the forward end of the syringe barrel, the valve device comprising a valve configured to control fluid communication between the syringe barrel and the interior of the fluid-bag.

7. A syringe device comprising:

a syringe barrel having an internal chamber and forward and back ends, the forward end configured to both removeably couple with a fluid-bag and expel fluid from the interior of the barrel, the opposing back end defining an interior circumference and configured to receive a syringe piston;

a syringe piston having a first end insertable into the internal chamber, a second end, and a stem extending from the first end to a container housing, the container housing extending to the second end and being configured to house a container, at least a portion of the container housing being insertable within the internal chamber, wherein the container housing comprises a cylindrical sidewall having at least one access window configured to allow removal of a lid from an enclosed container, and extraction of the lid from the housing, the window being insufficiently large to allow passage of the container therethrough; and

a fluid passageway extending from the container housing through the piston stem and through the first end of the piston.

8. The syringe device of claim 7 wherein the container housing comprises an internal chamber having sidewalls, at least a portion of the sidewalls having texture.

9. The syringe device of claim 8 wherein the texture comprises at least one of ribs and bumps.

10. The syringe device of claim 7 further comprising a vial-piercing device within the container housing.

11. The syringe device of claim 7 further comprising a luer-lok fitting configured to attach to a corresponding luer-lok fitting on a container.

12. A syringe device comprising:

a syringe barrel having forward and back ends, the forward end configured to both removeably couple with a fluid-bag and expel fluid from the interior of the barrel, the opposing back end defining an interior circumference and configured to receive a syringe piston;

a piston having a forward end insertable within the syringe barrel and having an enclosed vial housing containing a vial, the vial housing having cylindrical sidewalls, a base opposing the forward end of the syringe, and an access window through the sidewalls of sufficient size for manual removal of a vial lid and extraction of the lid from the housing without allowing passage of the vial through the opening, the vial housing having sidewalls defining an exterior circumference less than that of the barrel and insertable into the barrel; and

a fluid passageway through the piston from the vial housing to the forward end.

13. The syringe device of claim 12 wherein the cylindrical sidewalls are textured on an interior surface.

14. The syringe device of claim 12 wherein the vial housing is a two-part housing and wherein the two parts are sealed.
