A fluid collection apparatus is provided that includes a housing and a slide that is moveably supported by the housing. The slide has a cannula tab adapted to support a double ended needle and a plurality of connected segments that are moveably extending therefrom. Proximal movement of the slide causes the plurality of segments to contract in a configuration forming a shield about a proximal end of the double ended needle. The housing may define a slot in an outer surface thereof that is configured to receive a portion of the slide for guiding movement. The cannula tab can include a boss disposed adjacent a distal portion of the slide having the double needle mounted thereto. The cannula tab may include a segment member having a button mounted thereto which is disposed within at least a portion of the slot and slideably engages the slot to facilitate movement of the slide. The plurality of segments can include an end portion extending from a proximal end thereof. The end portion is disposed within a portion of the slot and cooperatively engages the slot to facilitate contraction of the plurality of segments. |
