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.

Safety needle accessory

A safety needle for automatically covering a tip of a needle following removal of the needle from a patient is provided. The safety needle includes an injection device and a packing sleeve. The injection device has an initial position and an intermediate position. The packing sleeve has a generally hollow body surrounding at least a portion of the injection device in the initial position and the intermediate position. The hollow body includes at least one track having an activation leg and a releasing leg. The at least one track is configured to slidingly engage with at least one member of the injection device to move the injection device to the intermediate position. The packing sleeve is removable from the injection device only when the injection device is in the intermediate position.

Safety needle

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. The releasing leg extends from the second end of the activation leg and allows the at least one member to be slid toward and then removed from the proximal end of the body.

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.

A safety needle pack to prevent needle stick injuries includes a hollow needle, a needle hub, a slidable sleeve 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. 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.

An injection aid is provided for use in injecting material through the skin of a recipient at a precisely defined point. The injection aid has a boss or the like which receives the outlet end of the injector. The injection aid is maintained at the desired location on the skin. In one embodiment, designed for use in treating erectile dysfunction, this is achieved by a C-shaped ring, and in another embodiment this is achieved by an adhesive-coated flange.
