  • Patent number: 9408632
    Abstract: A needle-based medical device and method of manufacturing the same are disclosed. A needle device includes a hub having a longitudinal axis; a needle having a sharp distal tip; and a needle shield assembly associated with the needle and moveable from a non-shielding position to a shielding position. In the shielding position, the sharp distal tip is covered by at least part of the needle shield assembly. A bushing disposed about the needle, and a latch for engaging with the hub when the needle shield assembly is in the non-shielding position are further provided.

  • Patent number: 9278195
    Abstract: A passively activated needle shield assembly with a hub engagement member for a needle device is provided. The needle shield assembly includes a needle shield movable between a non-shielding position and a shielding position. The needle shield prevents emergence of a sharp distal end of a needle therefrom in the shielding position. An engagement member is slidingly disposed relative to the needle shield for engaging the hub to the needle shield in the non-shielding position. A retainer operatively couples to the engagement member and is positioned to prevent disengagement of the engagement member from the hub in the non-shielding position, and enables removal of the hub from the needle shield by disengaging the engagement member from the hub when the needle shield moves to the shielding position.

In the shielding position, the sharp distal tip is covered by at least part of the needle shield assembly. A latch is further provided for engaging with the hub when the needle shield assembly is in the non-shielding position; as well as a locking member operably connected to the needle shield assembly, and located at least partially within the hub when the needle shield assembly is in the non-shielding position.

  • Patent number: 9174029
    Abstract: A needle assembly with a needle shield is disclosed. The shield includes a lumen slidable on the needle, a holder and a needle blocking object which moves at least partially into the lumen in order to block distal movement of the needle. A spring biases the blocking object towards the needle axis. Proximal movement of the needle relative to the shield is limited by a restraint in the form of a discontinuity on the needle which abuts the shield, a tether or a tube abutting the needle hub. When the needle shield moves from a non-shielding position to a shielding position, the needle blocking object moves at least partially into the lumen. The needle blocking object is radially and axially constrained in the shielding position. The holder also prevents radial, longitudinal and circumferential movement of the blocking object. In one embodiment, the needle blocking object is a ball. A catheter adapter and tube may be threaded over the needle.

  • Patent number: 8968240
    Abstract: Methods of manufacturing a catheter introducer or needle assembly and needle shield are disclosed. A needle shield has a blocking object (preferably a ball) which moves from an non-shielding position to a shielding position. The catheter introducer is made by placing the blocking object into the shield and inserting the proximal end of the needle into the shield while the blocking object is in the shielding position. The catheter introducer is made using extruded polymeric tubes which may have coextruded reinforcing.

  • Publication number: 20120123332
    Abstract: A needle-based medical device and a method for constructing it are disclosed. The medical device includes a needle blocking object movable from a non-blocking position offset from the longitudinal axis of the needle to a blocking position; a needle shield housing, the needle shield housing including: a lumen for accommodating at least part of the needle such that the needle shield housing; an opening for accommodating at least part of the needle blocking object; and a biasing member for applying a biasing force on the needle blocking object, the biasing force including a first component substantially perpendicular to the longitudinal axis of the needle and a second component substantially parallel to the longitudinal axis of the needle. The needle blocking object moves by exertion of the biasing force to the blocking position, preventing the needle from emerging from the needle shield housing, in response to a triggering proximal movement of the needle.

  • Publication number: 20120071831
    Abstract: A needle-based medical device including a needle shield assembly and a method for constructing the same are disclosed. The needle shield assembly may be deployed such that the device shields the needle passively on removal. A needle shield assembly includes a shield including a restraint member at a proximal end for engagement by an actuator in a non-shielding position. The needle shield assembly includes a shield having a stepped end cap at its distal end; a carrier positioned at the distal end of the shield that supports a needle blocking object abutting a first step of the end cap in the non-shielding position; and a biasing member within the shield for applying an axial force to the shield. Movement of the actuator disengages the restraint member such that the shield moves, by exertion of the biasing member, from the non-shielding position to a shielding position.

  • Patent number: 8002746
    Abstract: A winged needle set is disclosed. The winged needle set has a housing and opposed wings which can be grasped between the fingers for insertion of the needle into a body. The winged needle set has a finned member which is rotatable about the axis of the needle. Rotation of the finned member towards one of the wings actuates a needle shield, which moves along the needle in the distal direction. In one embodiment, the needle shield has includes a blocking object (such as a ball), a biasing spring and a holder for the blocking object.
