Abstract: This invention relates to a safety needle accessory sealed within a pack suitable for sealing pre-filled syringes. The safety needle accessory comprises a hub for surrounding a hollow needle having a tip and having a connector for attachment to a syringe, a slidable sleeve adapted to slide over the needle in a first longitudinal direction from a first position in which the needle is fully or partially covered by the sleeve to a second position in which the needle is exposed, and in a second longitudinal direction from the second position to a third position in which the needle is fully covered by the sleeve, and a pack surrounding the hollow needle, hub and slidable sleeve having a closed end covering the needle and an open end exposing the connector of the hub. The safety needle accessory further comprises a first seal attached to the connector of the hub and a second seal between the hub and the pack.

Abstract: A safety needle accessory is provided for the prevention of needle stick injuries. The safety needle accessory includes a hollow needle, a hub surrounding a base of the hollow needle, a sleeve surrounding the hub, and a elastically deformable member. The sleeve is slidable to a first, a second and a third position in which the sleeve fully or partially covers the needle. In addition, the safety needle accessory includes a pack having a removable cap. The cap is removable from the pack while a remainder of the pack remains mounted over the needle, hub and sleeve. The cap is removed from the pack at a position such that removal of the cap exposes a sharp end of the needle, but not the sleeve, when the sleeve is in the intermediate position.

Abstract: A packing sleeve for use with a safety needle that automatically covers a tip of a needle following removal of the needle from a patient includes a generally hollow body having a longitudinal axis and a distal end and an open proximal end. The body surrounds at least a portion of the safety needle and has at least one track having an activation leg and a releasing leg. The at least one track is in sliding engagement with at least one member of the safety needle such that the motion of a portion of the safety needle relative to the body is dictated by a path the at least one member follows along the respective at least one track. The safety needle is in an initial position when the at least one member is proximate a first end of the activation leg and in an intermediate position when the at least one member is proximate a second end of the activation leg.

Abstract: A safety needle accessory includes a hub (6) having a connector (2) for surrounding a hollow needle. The hub has a first seal (10) that engages sealingly with the connector. A slidable sleeve (8) slides over the needle in a first longitudinal direction from a first position in which the needle is fully or partially covered by the sleeve to a second position in which the needle is exposed to a third position in the second direction in which the needle is fully covered by the sleeve. A pack (9) having a closed end surrounds the hollow needle, hub and slidable sleeve. The pack has a first section which abuts the hub or the first seal to form a second seal and the pack has a second section which engages the needle tip to form a third seal (12) between the closed end of the pack and a needle tip.

Abstract: This invention relates to an accessory for attaching to a needle to prevent needle stick injuries. The safety needle accessory is suitable for use with a hollow needle and comprises a needle hub surrounding the needle and a slidable sleeve slidably mounted on the needle hub. The slidable sleeve bears resiliently on the needle hub such that, in use, as the slidable sleeve is caused to move into a retracted position. A restoring force is generated within the slidable sleeve and on removal of the needle from the patient the restoring force causes the slidable sleeve to move into an extended position covering the needle tip. The safety needle locks in this position after removal of the needle from the patient.

Abstract: A safety needle for automatically covering a needle tip following removal of the needle from a patient includes a hub mounted to the needle. A slidable sleeve is slidably mounted to the hub and has an extended position in which a tip of the needle is located inside the slidable sleeve and a retracted position in which the tip of the needle projects from the slidable sleeve. An outer surface of the hub deflects the slidable sleeve in a radial direction as the slidable sleeve slides in an axial direction toward a receiving end of the hub. A spring member is mounted to the slidable sleeve proximate the mounting end. A displacement force urges the slidable sleeve toward the retracted position and generates a restoring force within the spring member. The restoring force urges the slidable sleeve to move toward the injection end of the needle hub and into the extended position upon removal of the displacement force.

The pack has a first section which abuts the hub or the first seal to form a second seal and the pack has a second section which engages the needle tip to form a third seal (12) between the closed end of the pack and a needle tip.

Abstract: This invention relates to a safety needle to prevent needle stick injuries. The invention provides a safety needle accessory comprising a hollow needle having a base end and a sharp end, a hub surrounding the base end of the needle and having a connector for connection to an injection device, a sleeve surrounding the hub and slidable relative to the hub in an axial direction, an elastically deformable member, and a pack having a closed end covering the sharp end of the needle and an open end exposing the connector of the hub and which is releasably mounted over the needle, hub and sleeve.

Abstract: This invention relates to a safety needle pack to prevent needle stick injuries. The safety needle pack comprises a hollow needle, a needle hub surrounding the hollow needle, a slidable sleeve slidably mounted on the needle hub and a pack surrounding the needle, hub and sleeve. The slidable sleeve is adapted to slide between an extended position in which the injection end of the needle is located inside the slidable sleeve and a retracted position in which the injection end of the needle projects from the slidable sleeve, via an intermediate position between the extended position and the retracted position in which the injection end of the needle projects partially from the slidable sleeve. The pack is releasably mounted on the needle hub and slidable sleeve such that the injection end of the pack covers the tip of needle. By causing the pack to be moved towards the syringe, the pack retracts the slidable sleeve from the extended position to the intermediate position.
