Abstract

A syringe for administering medicament from a cartridge. The syringe includes a sleeve having an interior for receiving the cartridge extending between a distal hub and a proximal opening. The syringe has a cap selectively covering the proximal opening for retaining the cartridge in the interior of the sleeve. The cap includes a finger grip extending outward from the sleeve for engaging fingers of a user. The syringe also has a plunger rod movably connected to the cap. The plunger rod has a distal connector for selectively connecting the rod to the cartridge plunger when the cartridge is received in the interior of the sleeve to push medicament from the cartridge reservoir as the plunger rod moves with respect to the cap.

a catheter having a proximal end fluidly connected to the distal hub of the sleeve and a distal end fluidly connected to a needle.

10. The syringe of claim 9, further comprising a ring positioned on the second needle adapted to engage a user'"'"'s finger.

11. The syringe of claim 10, wherein the needle further comprises a protrusion extending outwardly from a side of the needle.

12. A syringe for administering medicament from a cartridge, the syringe comprising:

a sleeve having an interior sized and shaped for receiving the cartridge extending between a distal hub and a proximal opening opposite the hub sized and shaped for delivering the cartridge to the interior;

a cartridge having a medicament reservoir and a plunger, the cartridge disposed within the sleeve;

a cap permanently affixed to the sleeve and covering the proximal opening for retaining the cartridge in the interior of the sleeve, the cap including a finger grip extending outward from the sleeve for engaging fingers of a user administering medicament; and

a plunger rod positioned over the needle and removably affixed to the distal hub of the sleeve, the plunger rod movably connected to the cap and having a distal connector for connecting the rod to the cartridge plunger when the cartridge is received in the interior of the sleeve to push medicament from the cartridge reservoir as the plunger rod moves with respect to the cap.

13. The syringe of claim 12, wherein the plunger rod is adapted to be removably affixed to the hub by a threaded connection.

14. The syringe of claim 13, wherein the plunger rod is adapted to be secured to the cartridge by a threaded connection.

15. The syringe of claim 12, wherein the sleeve includes a lock ring configured to engage the cartridge to prevent separation of the sleeve from the cartridge.

16. A syringe for administering medicament from a cartridge having a medicament reservoir and a plunger positioned adjacent reservoir for pushing medicament from the reservoir, the syringe comprising:

a sleeve having an interior sized and shaped for receiving the cartridge extending between a distal hub and a proximal opening opposite the hub sized and shaped for delivering the cartridge to the interior;

a cartridge disposed within the sleeve;

means for limiting movement of the cartridge towards the proximal opening of the sleeve;

a needle extending into the sleeve from the distal hub for piercing the cartridge to access medicament in the cartridge reservoir; and

a plunger rod movably connected to the sleeve, the plunger rod having a distal connector for connecting the rod to the cartridge plunger to push medicament from the cartridge reservoir as the plunger rod moves with respect to the sleeve, the plunger rod being adapted to move the plunger of the cartridge between a first position, in which the septum is not pierced by the needle and the plunger of the cartridge is in a proximal location, and a second position, in which the septum is pierced by the needle and the plunger of the cartridge is in a distal location.

17. The syringe of claim 16, wherein the syringe sleeve includes a detent located on an inner wall of the sleeve.

18. The syringe of claim 17, wherein the detent is adapted to space the cartridge from the needle to prevent the needle from penetrating the septum before the syringe prepared for use.

20. A syringe for administering medicament from a cartridge having a medicament reservoir and a plunger positioned adjacent the reservoir for pushing medicament from the reservoir, the syringe comprising:

a sleeve having an interior sized and shaped for receiving the cartridge extending between a distal hub and a proximal opening opposite the hub sized and shaped for delivering the cartridge to and from the interior;

a needle extending from the distal hub for piercing a patient;

a flange adapted to engage a proximal end of the cartridge and a ratchet protrusion permitting the flange to move distally with respect to the sleeve and preventing the flange from moving proximally with respect to the sleeve so the ratchet protrusion retains the cartridge in a pre-armed state, in which the needle does not pierce the septum, before the flange is moved distally with respect to the sleeve and the ratchet protrusion prevents proximal movement of the flange with respect to the sleeve and retains the cartridge in an armed state, in which the needle pierces the septum, after the flange is moved distally with respect to the sleeve; and

a needle extending into the sleeve; and

a barrier positioned between the needle and the cartridge when received in the sleeve to prevent the needle from piercing the septum of the cartridge, wherein removal of the barrier permits the needle to pierce the septum to permit flow of medicament from the cartridge through the needle.

26. The syringe of claim 25, wherein the barrier is removably positioned between the needle and the cartridge.

27. A device for delivering medicament comprising:

a sleeve;

a medicament reservoir positioned within the sleeve;
