Shield apparatus for syringe needle
First Claim
1. Needle safety shield apparatus for a syringe needle comprising in combination:
- base means to be secured to a syringe, including a locking pin,cylinder means pivotally secured to the base means for shielding the syringe needle, includinga cylinder disposed over the needle and pivotable on the base means,a locking slot for receiving the locking pin when the cylinder is pivoted to expose the needle to lock the cylinder means to the base means,hinge means for pivoting the cylinder, anda slot in the cylinder aligned with the hinge means through which the needle extends when the cylinder means pivots on the base means to expose the needle;
means for rotating the cylinder relative to the syringe and the needle to align the needle with the slot to allow the needle to pass through the slot to expose the needle; and
means for securing the base means to the syringe.

Abstract
Hypodermic needle safety apparatus includes an embodiment having a shield which includes a longitudinal slot and a cover which rotates on the shield and an embodiment in which the shield must be moved axially, along the longitudinal axis of the syringe and needle, to allow the needle to be moved through a slot for use. The shield is then pivoted by thumb or finger movement so that the needle moves through the exposed slot to allow use of the syringe and the needle. The shield or cover moves through an arc of about 180 degrees so that the shield is away from the needle during the use of the needle and syringe. The shield is pivoted back downwardly to cover the needle and then the shield is again moved longitudinally or axially so that the bottom of the needle is away from the slot. The longitudinal or axial movement of the cover or shield requires a positive movement, and accordingly the shield may not be accidently or inadvertently pivoted away from the needle to expose the needle.

12. Hypodermic syringe and shield apparatus comprising in combination:
-
a syringe having a first diameter; a needle secured to the syringe; shield means secured to the syringe and disposed over the needle for shielding the needle, including a needle shield secured to the syringe having a second diameter which is less than the first diameter of the syringe for preventing the needle shield from moving axially along the syringe, hinge means for pivoting the needle shield relative to the syringe and the needle, and a slot in the needle shield through which the needle moves as the needle shield pivots to expose the needle for use; and
an outer shield disposed over the needle shield. - View Dependent Claims (13, 14, 15, 16)
