Abstract

A syringe device that includes a stem, container, and a plunger, the plunger having tubes with a soluble substance that maintain a seal on compounds within the container's chamber, and/or a parabolic cover held in position by a soluble substance, thus allowing a multi-cycle usage to dispense medication to patients, even while preventing further use.

Claims (47)

1. A syringe device, wherein said syringe device comprises:

a stem, wherein said stem comprises an axial chamber;

a plunger; and

a container, wherein said container comprises a chamber:

wherein said plunger further comprises a cover and a tube, and wherein said tube allows fluid communication between said chamber and said axial chambers when said cover is open;

wherein when said cover is closed, said cover prevents fluid communication between said chamber and said axial chamber; and

wherein said plunger further comprises a protrusion, and wherein said cover is secured to said protrusion in said closed position via a soluble substance.

2. The syringe device of claim 1 , wherein said stem further comprises a secondary channel, and wherein said secondary channel provides fluid communication between said chamber and said tube, and said axial chamber.

3. The syringe device of claim 1 , wherein said protrusion is parabolic.

4. The syringe device of claim 1 , wherein said cover is secured to said protrusion via said soluble substance positioned proximate a periphery of said cover.

5. The syringe device of claim 1 , wherein said tube comprises said soluble substance.

6. The syringe device of claim 5 , wherein said soluble substance is positioned within said tube, and prevents fluid communication between said chamber and said axial chamber.

7. The syringe device of claim 5 , wherein when said soluble substance positioned within said tube dissolves, said tube allows fluid communication between said chamber and said axial chamber.

8. The syringe device of claim 1 , wherein said plunger further comprises a cavity, and wherein said tube comprises a tube bottom in fluid communication with said cavity.

9. The syringe device of claim 8 , wherein said stem further comprises a base, and wherein said base is disposed against said cavity, and prevents fluid communication between said chamber and said axial chamber.

10. A method of using a syringe device of claim 1 , said method comprising the step of:

injecting said syringe into a vial holding a suspension media, wherein said soluble substance prevents fluid communication between said chamber and said axial chamber.

11. The method of claim 10 , said method further comprising the steps of:

pushing said stem inward to create positive pressure inside the vial of the suspension media; and

pulling said stem outward to draw the suspension media into the syringe, wherein said soluble substance begins dissolving.

12. The method of claim 11 , said method further comprising the steps of:

pushing said stem inward to inject the suspension media into a vial of a dried medication; and

pulling said stem outward to draw the medication now in suspension into the syringe.

13. The method of claim 12 , said method further comprising the steps of:

pushing said stem inward to inject the medication into a patient; and

dissolving said soluble substance, wherein said chamber and said axial chamber are in fluid communication if said stem is not being pushed inward.

14. A syringe, where said syringe comprises:

a stem, wherein said stem comprises a depresser and an axial chamber;

a plunger; and

a container, wherein said container comprises a chamber;

wherein said plunger further comprises a conical shaped tube, and wherein said conical shaped tube allows fluid communication between said chamber and said axial chamber; and

wherein said conical shaped tube further comprises a soluble substance, wherein said soluble substance prevents fluid communication between said chamber and said axial chamber.

15. The syringe of claim 14 , wherein said stem further comprises a secondary channel, and wherein said secondary channel provides fluid communication between said chamber and said conical shaped tube, and said axial chamber.

16. The syringe of claim 14 , wherein said soluble substance positioned within said conical shaped tube dissolves, said conical shaped tube allows fluid communication between said chamber and said axial chamber.

17. The syringe of claim 16 , wherein said stem further comprises a base, and wherein said base comprises a base top, said plunger further comprises a cavity in fluid communication with said conical shaped tube having a tube bottom, and said base is disposed within said cavity; and wherein said base top is disposed proximate said tube bottom when said stem is being pushed inward to prevent fluid communication between said chamber and said axial chamber.

18. The syringe of claim 14 , wherein said plunger further comprises a protrusion having a cover, and wherein said cover is secured to said protrusion via said soluble substance to prevent fluid communication between said chamber and said axial chamber via said conical shaped tube.

19. The syringe of claim 18 , wherein said soluble substance positioned therein dissolves and releases said cover, said conical shaped tube allows fluid communication between said chamber and said axial chamber.

20. A syringe device, wherein said syringe device comprises:

a stem, wherein said stem comprises an axial chamber;

a container, wherein said container comprises a chamber, and wherein said soluble substance prevents fluid communication between said chamber and said axial chamber;

a plunger, wherein said plunger further comprises a cover and a tube, and wherein said tube allows fluid communication between said chamber and said axial chamber when said cover is open, and wherein said plunger further comprises a protrusion, and wherein said cover is secured to said protrusion via said soluble substance.

21. The syringe device of claim 14 , wherein said stem further comprises a secondary channel, and wherein said secondary channel provides fluid communication between said chamber and said axial chambers.

22. The syringe device of claim 21 , wherein said plunger further comprises a cavity, and wherein said conical shaped tube comprises a tube bottom, and wherein said tube bottom is in fluid communication with said cavity.

23. The syringe device of claim 22 , wherein said stem further comprises a base, and wherein said base is disposed against said cavity, prevents fluid communication between said chamber and said axial chamber.

24. The syringe device of claim 20 , wherein said cover prevents fluid communication between said chamber and said axial chamber when said cover is closed.

25. The syringe device of claim 21 , wherein said plunger further comprises a cavity, and wherein said tube comprises a tube bottom, and wherein said tube bottom is disposed at said cavity.

26. The syringe device of claim 25 , wherein said stem comprises a base, and wherein said base is disposed against said cavity.
