Abstract: A safety shield for use with a hypodermic syringe device is disclosed. The safety shield is moveable relative to the syringe barrel between refracted position and a needle containing position. In the retracted position, the syringe device may be used to inject the needle into the patient.

Abstract: Embodiments of the present safety needle assembly include a slidable needle shield. Digital pressure applied to a leaf spring retention latch removes a compressive force from a biasing member and automatically moves the needle shield from a ready-to-use configuration to a protected configuration in which the needle shield covers the sharp needle tip. In the protected configuration the needle shield is prevented from sliding proximally along the needle a sufficient distance to expose the needle tip.

Abstract: A safety device for shielding the sharp tip of a medical needle has a needle mount which either directly supports a medical needle, or indirectly supports the needle for instance where the needle is provided as a part of a syringe. A sleeve is carried directly or indirectly on the needle mount and is slidably movable to a needle shielding position where the sleeve surrounds the needle sharp tip. A spring including forwardly projecting spring blades when sufficiently loaded acts on an internal conical surface of the sleeve to drive the sleeve to its shielding position and a locking mechanism then locks the sleeve in that position. A camming mechanism serves to load the spring blades in the course of the use of the safety device such that thereafter the interaction of the blades with the conical surface urges the sleeve to its shielding position, the camming mechanism being activated by movement of the sleeve to expose the needle for use.

Abstract: A safety needle assembly is provided herein having a hub; a needle fixed to the hub; a shield; a tab; a spring disposed between the shield and the hub configured to bias the shield distally; and, a clip disposed between the hub and the shield, the clip having a notch formed thereon shaped to permit passage therethrough of the tab. The clip and the tab releasably retain the shield in a first locked state against the biasing force of the spring thereby limiting distal movement of the shield relative to the hub; yet, in the first locked state, the shield is movable proximally relative to the hub. In the first locked state, the notch is spaced from the tab. The clip and the tab are relatively displaceable so as to align the notch with the tab and release the shield from the first locked state thereby allowing the shield to move distally, relative to the hub, to a second shielded state. In the second shielded state, the distal end of the needle is covered by the shield.

Abstract: In an elongated casing, an active agent container connected to an injection needle can be shifted axially by a spring force. Auto-injectors which are sold or distributed filled and with the springs tensed have to be provided with a needle protecting cap to ensure the sterility of the injection needle. When such a needle protecting cap is removed as preparation for using the auto-injector, a tensile force can be exerted on the active agent container. Therefore, the active agent container comprising the injection needle must be prevented from being undesirably pulled forwards. At least one latching tongue prevents the active agent container from being prematurely shifted with respect to the casing, by abutting a flange arranged on a sliding sleeve which accommodates the active agent container. When the auto-injector is placed onto a person's skin, a needle protecting tube is shifted into the casing, forcing the latching tongue away from the flange and, thus, freeing the travel path for needle movement.

In some implementations, the syringe assembly includes a lock that inhibits the assembly from returning to the pre-injection configuration once an injection is delivered. The syringe assemblies may also include a bevel orientation mechanism that allows a user to align a needle bevel to accurately insert a needle for injection.
