20140046272 | RELEASE MECHANISM FOR USE WITH NEEDLE SHIELDING DEVICES - 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 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. The latch and locking member lock the latch to the hub, such that when the needle shield assembly moves into the shielding position, the locking member moves generally proximally, unlocking the latch. | 02-13-2014 |
20140025009 | NEEDLE SHIELDING DEVICE - 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. | 01-23-2014 |
20130296805 | NEEDLE SHIELD ASSEMBLY WITH HUB ENGAGEMENT MEMBER FOR NEEDLE DEVICE - 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. | 11-07-2013 |
20120123332 | NEEDLE-BASED MEDICAL DEVICE AND RELATED METHOD - 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. | 05-17-2012 |
20120071831 | NEEDLE-BASED MEDICAL DEVICE WITH NEEDLE SHIELD - 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. | 03-22-2012 |
