Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.

A needle protection assembly, adapted to protect a tip of a hypodermic needle, comprising a shield adapted, in a protected operative orientation of the needle protection assembly, to shield the tip of the hypodermic needle, a locking element including at least one slot, the slot including at least three surfaces corresponding to three operative orientations of the shield, at least one slot engaging element, functionally associated with the shield, the slot engaging element being disposed within the slot of the locking element and movable relative thereto, between the surfaces, so as to transition the shield between the three operative orientations, and at least one biasing element, adapted for axial biasing of the shield, wherein the three operative orientations include a storage operative orientation, an injection operative orientation, and a needle protection operative orientation.

The present disclosure relates to a disposable injection needle including: a needle mount having a tube needle; a first sleeve, one end of which is suitable for connecting to the needle mount to define receiving space, and the other end of which is provided with a first opening; a second sleeve, one end of which is located inside the receiving space, and the other end of which having a second opening; an elastic element adapted to allow the second sleeve moves axially toward outside the receiving space, wherein: the needle mount or the first sleeve is provided with a stop surface and a limit groove; the second sleeve is provided with a limit arm comprising a limit face and a protruding member which is adapted to enter the limit groove with axial relative movement between the first sleeve and the second sleeve.

A reusable safety syringe training device is provided. The device comprises a syringe contained within a syringe protective member. The syringe protective member is movable vertically within an outer protective sheath from a first position to a second position and back to the first position. In the first position, the device is in an injection-ready position with the needle exposed and the syringe protective member in a locked vertical position with respect to the outer protective sheath. In the second position, the device is in a post-injection position such that the syringe protective member is no longer vertically locked with respect to the outer protective sheath and has moved vertically upward thereby rendering the needle within the outer protective sheath. The plunger carries a release flange sufficient to engage release latches that otherwise retain the syringe protective member in the first position. The release flange engages that release latches when the user pushes the plunger down to effectuate the injection. Once pressure is removed from the plunger after the injection has concluded, a springe mechanism drives the syringe protective member upwards to the second position. The user can then turn the plunger such that the release flange is no longer able to engage the release latches and push the plunger back down to lock the syringe protective member in its first position. The user is then able to pull the plunger back up while the syringe protective member remains locked, turn the plunger back to a position where the release flange is in a position to engage the release latches again, and perform another injection.

Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.

An extravascular system is provided which includes a catheter adapter having a blood control septum configured to control flow of a fluid through the catheter adapter, the catheter adapter further having a catheter configured for intravenous insertion. The extravascular system further includes a septum activator slidably inserted within the catheter adapter and configured for advancement through the blood control septum to provide a fluid pathway through the blood control septum. Further still, the extravascular system includes an external safety mechanism comprising a needle hub and a needle shield interconnected via a tether, wherein the needle shield includes a safety clip that is configured to retain a sharpened end of the introducer needle within the needle shield. Some implementations further comprise an access port forming a portion of the catheter adapter and providing selective access to the lumen of the catheter adapter.
