Abstract
A needle assembly includes a needle member ( ) and a blunting member ( ), the needle member ( ) containing a needle cannula ( ), the needle cannula ( ) having a puncture tip ( ) and having a needle passageway therethrough. The blunting member ( ) contains a blunting probe ( ) having a blunt end ( ). The needle cannula ( ) and the blunting probe ( ) are disposed telescopically one within the other without obstructing flow through the needle passageway, and are movable between a sharpened configuration in which the puncture tip ( ) of the needle cannula ( ) is exposed and a blunted configuration in which the blunt end ( ) of the blunting probe ( ) extends beyond the puncture tip ( ) to blunt the needle assembly. The assembly may be combined with an accessory device (such as a catheter hub, guide wire, etc.) to produce an apparatus that is lockable in a blunted configuration and that can be released by the associated accessory, or may be configured to be released by manual manipulation.
