A safety cover configured to be coupled to an injection device and to provide a protective enclosure for a needle of the injection device, the safety cover including an outer cover member; an inner cover member coupled to the outer cover member in a concentric arrangement so that the outer cover member encloses at least a portion of the inner cover member, wherein the outer cover member is configured to move relative to the inner cover member from an unlocked position, in which the needle of the injection device is accessible for use, to a locked position, in which the outer cover member and the inner cover member are fixed at one another and the needle of the injection device is inaccessible, wherein the outer cover member includes a body that includes a proximal end, a distal end, and a cavity defined within the body.

A medical syringe apparatus includes a syringe unit, a hypodermic needle attached to the syringe unit and at least one interfacing member for mating a labeled medication container to the syringe unit. A filling needle is attached to the syringe unit for drawing fluid from a container. A movable needle sheath protects the hypodermic needle when not in use and may be moved out of the way when administering an injection. The medication label is visible. The container remains mated to the syringe when the syringe is in use. Risk of mislabeling the syringe may therefore be substantially reduced or eliminated and patient safety may accordingly be improved.

The invention relates to a safety assembly havingan attachment ring attached to the tip of the container anda safety device covering at least the distal end of the needle, the safety device attached to the attachment ring. The attachment ring has an inner ring having an inner face provided with a snap feature, which engages a complementary snap feature on the tip of the container to prevent axial movement of the inner ring with respect to the container. The snap feature moves radially to engage the complementary snap feature on the tip of the container; and an outer ring is fixed on the inner ring, with a sleeve portion surrounding at least a portion of the inner ring to prevent radial movement of the snap feature once the snap feature has engaged the complementary snap feature on the tip of the container.

A needle assembly includes a needle and a needle shield device. The needle shield device includes an inner shield connectable to at least one a base and a fluid connector connectable to the base, and an outer shield fixedly connected to the opposing end the needle and displaceable relative to the inner shield between a first position, in which the sharpened end of the needle is exposed outside the inner shield, and a second position, in which the sharpened end of the needle is shielded by the inner shield. Interaction between portions of the inner and outer shields during or after proximal displacement of the outer shield from the first position to the second position automatically releases or permits release of the inner shield from connection to the at least one of the base and the fluid connector.

A segmented safety cover may include a proximal segment combined with a needle hub; a needle cannula that extends from the proximal needle hub to a distal sharpened end; a distal end cap with a hollow bore through which the needle cannula passes; a centrally mounted toggle locking mechanism, separating the proximal needle hub from the distal end cap; the toggle locking mechanism is torsion spring assisted; a proximal cover segment is connected to the hub via a proximal hinge and a distal cover segment is connected to the end cap via a distal hinge; said proximal cover segment and said distal cover segment of said toggle locking mechanism being configured with abutting faces when the segmented safety cover is in a safety mode; and wherein the proximal hinge, abutting faces and distal hinge are in line in the safe mode.

A syringe needle shield that includes a first part and a second part. The first part is connected to the second part by a pivotable first connection portion. The second part is pivotable on the first connection portion toward the first part, and a needle hub is clamped between the first and second parts. The first and second parts are securely connected to each other by the first snapping portion which cannot be unlocked from each other. The first part is connected to a needle shield by a flexible plate. The shield receives a push force from its back so as to move from a first position to a second position. When the shield is located at the second position, a restriction portion is fixedly engaged with an engaging portion.

Provided are an intradermal needle having a protector that is movable from an open position near a needle hub to a closed position where a needle tip is covered, a packaged article, and an injection device. The protector has an arm that is supported in a freely pivotable manner by an axle pin positioned on the base end side of the wide diameter part of the intradermal needle, and a lid supported by the arm. With the axle of pivoting of the protector positioned near the needle hub, the lid may be housed compactly near the needle hub when the protector is in the open position.

In an intradermal needle including a tubular needle that can be punctured into a living body, a packaging article, and an injection device, a pivotable protector is provided to a wide diameter part. The protector has an arm that can pivot around an axle of pivoting, and a lid. The pivoting axle part is provided to the wide diameter part, and the lid is formed to give a width smaller than a diameter of the wide diameter part. The arm keeps the lid in the open position away from the pivoting axle part and closer to an axis of the needle hub.

A safety device for preventing needlestick injury with a needle, including a protective cap and a shield capable of pivoting from a storage position where it is interlocked with the protective cap, a retracted position where it gives access to the needle and a safety position where it covers the needle, wherein a cam surface of the shield and an engaging peg of the protective cap are arranged so that, when the safety device is mounted around the tip of a medical device, removing the protective cap from the tip by a distal movement displaces the shield from the storage position to the retracted position. A medical device including a tip provided with a needle including a needle point, wherein the medical device further includes a safety device.

Embodiments of the shield assemblies include a shield that is pivotably secured to a needle hub. A ball-and-socket hinge secures the shield and the hub to one another. The assembly includes a reversible shield lock to hold the shield in the needle-protected position.
