Abstract

An apparatus for removing a needle shield from a syringe may be configured to receive the removable needle shield. The remover may include a body and a deflectable arm. The deflectable arm may include a distal end coupled to the body and a proximate end distal a proximate end of the body. The deflectable arm may be configured to engage and apply a force to the needle shield when the cap is detached from the syringe, thereby removing the needle shield from the syringe.

First claim

I/we claim:

1 . An apparatus for removing a needle shield from a syringe, comprising:
a remover having a proximal-to-distal axis, a body, and an arm that is deflectable, the remover coupled to a syringe having a removable needle shield and configured to receive the removable needle shield, wherein the arm includes a distal end coupled to the body and a proximate end axially spaced from an end of the body, the arm configured to engage and apply a force to the needle shield when the remover is separated from the syringe, to thereby remove the needle shield from the syringe.

2 . The apparatus of claim 1 , wherein the body includes an opening and the arm is positioned within the opening.

3 . The apparatus of claim 1 , further comprising a cap detachably coupled to an injector and attached to the remover.

4 . The apparatus of claim 3 , further comprising:
a boss extending from the cap; and an aperture in the body configured to receive the boss to secure the remover to the cap.

5 . The apparatus of claim 1 , wherein the remover can rotate relative to the needle shield while engaged with the needle shield.

6 . The apparatus of claim 1 , further comprising:
a second deflectable arm, the arms moveable between a first configuration wherein the arms are flexed radially outward and a second configuration wherein the arms are aligned with the body.

7 . The apparatus of claim 6 , wherein the arms are in the first configuration when the arms are adjacent the syringe.

8 . The apparatus of claim 7 , wherein the arms are in the second configuration when the arms are adjacent a proximal end of the needle shield.

9 . The apparatus of claim 3 , further comprising a flange extending distally from the arm, the flange engaging and applying a force to the proximal end of the needle shield when the cap is detached from the syringe.

10 . The apparatus of claim 3 , wherein the proximal end of the deflectable arm is proximal to a proximal end of the cap.

11 . The apparatus of claim 3 , wherein the remover includes a central channel and the cap includes a projection extending proximally from a distal end of the cap and into the central channel when the remover is coupled to the cap.

12 . The apparatus of claim 1 , wherein the body includes a circumferential halo proximal to the opening.

13 . An apparatus for removing a needle shield from a syringe, comprising:
a cap detachably coupled to a syringe having a removable needle shield, the cap having a distal end and a projection extending proximally from the distal end; and a remover having a channel configured to engage the projection to secure the remover to the cap, the remover configured to receive the needle shield and apply a force to a proximal end of the needle shield when a force is applied to the cap to thereby remove the needle shield from the syringe.

14 . The apparatus of claim 13 , further comprising:
a boss extending from the projection; and an aperture in the remover configured to receive the boss to secure the remover to the cap.

15 . The apparatus of claim 13 , wherein a proximal end of the remover is proximal to a proximal end of the cap.

16 . The apparatus of claim 13 , wherein the remover includes an arm which engages the proximal end of the needle shield and a body, and wherein a proximal end of the arm is distal to a proximal end of the body.

17 . The apparatus of claim 16 , further comprising:
an opening in the body with the arm positioned in the opening.

18 . The apparatus of claim 16 , wherein the arm and body monolithically form the remover.

19 . The apparatus of claim 13 , further comprising:
a flange coupled to the remover and extending distally therefrom, the flange configured to engage and apply a force to a proximal end of the needle shield when a force is applied to the cap.

20 . The apparatus of claim 13 , wherein a diameter of the projection is greater than or equal to a diameter of the needle shield.

21 . The apparatus of claim 17 , wherein the body includes a circumferential halo proximal to the opening.

22 . The apparatus of claim 16 , wherein the arm is deflectable from a second position to a first position as the needle shield is positioned within the remover.

23 . The apparatus of claim 17 , further comprising at least one additional opening in the body, wherein the openings in the body are separated by struts.

24 . The apparatus of claim 21 , wherein a halo connects a proximal end of the struts.

25 . An apparatus for removing a needle shield from a syringe, comprising:
a remover having a proximal-to-distal axis, a body, and an arm that is deflectable, the remover coupled to a syringe having a removable needle shield and configured to receive the removable needle shield, wherein the arm includes a distal end coupled to the body and a proximate end axially spaced from an end of the body, the proximate end of the arm configured to be positioned on a barrel of the syringe when the remover is coupled to the syringe, the arm configured to engage and apply a force to the needle shield when the remover is separated from the syringe, to thereby remove the needle shield from the syringe.

26 . The apparatus of claim 25 , wherein the arm is deflected outwardly relative to a remover body when the remover is coupled to the syringe.

27 . The apparatus of claim 25 , wherein the remover includes a circumferential halo proximal to the arm.

28 . The apparatus of claim 25 , wherein the arm is deflectable from a second position to a first position as a force is applied to remove the needle shield.
