Patent number: 8109905Abstract: A fluid collection or infusion set is provided. The set includes flexible tubing with a fitting attached to a proximal end and a needle assembly attached to the distal end. The needle assembly includes a needle hub and a needle cannula secured in the hub. An actuator arm extends proximally and outwardly from the needle hub and has an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position where the needle cannula is exposed to a proximal position where the needle cannula is shielded. A spring is disposed in the barrel for propelling the needle assembly to the proximal position. The barrel includes an actuating aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal shielded position.Type: GrantFiled: October 8, 2007Date of Patent: February 7, 2012Assignee: Becton, Dickinson and CompanyInventors: William G.

Patent number: 7060055Abstract: The present invention is directed to a shieldable blood collection set as well as a needle assembly for use therein. The needle assembly includes a needle cannula having a puncture tip at a distal end thereof and a hub which supports the needle cannula. A hollow outer shield co-axially surrounds a distal end of the hub and has an inner surface which is in cooperating engagement with an outer surface of the hub. The hub includes a first tab extending outwardly at a position which is exposed from the outer shield, and the outer shield includes a second tab. The first tab and the second tab are configured such that opposing forces applied against the tabs cause the outer shield to move from a retracted position in which the puncture tip of the needle cannula is exposed, to an extended position in which the outer shield covers the puncture tip.Type: GrantFiled: July 28, 2003Date of Patent: June 13, 2006Assignee: Becton Dickinson and CompanyInventors: Bradley M.

Patent number: 6994213Abstract: A package is provided for a medical device that a spring-driven button-actuated safety shield. The package includes a tray with a bottom wall and sidewall enclosure that extends upwardly from the bottom wall a distance greater than the height or thickness of the medical device. A flange extends outwardly from edges of the sidewall enclosure opposite the bottom wall. At least two gripping towers are formed unitarily with the bottom wall and project upwardly a distance greater than the thickness or height of the medical implement. Gripping towers are spaced from one another and are configured to grippingly engage the medical implement on opposite respective sides of the actuating button for preventing inadvertent actuation of the safety shield while the medical implement is in the tray. A cover extends removably across the flange and is supported by the gripping towers.Type: GrantFiled: August 28, 2002Date of Patent: February 7, 2006Assignee: Becton, Dickinson and CompanyInventors: John A.

Patent number: 6855130Abstract: A passively shieldable needle assembly set is provided for use with a tube holder. The assembly includes a needle cannula, a hub mounted to the needle cannula and a tip guard slidably movable along the needle cannula. The tip guard can be slid into a distal position where the tip of the needle cannula is safely shielded. A collapsible guard drive is mounted to the hub and includes a pair of collapsible leaves extending from the hub to the tip guard. The leaves have a length that enable the tip guard to move into shielding engagement around the tip of the needle cannula, while preventing complete removal of the tip guard from the needle cannula. The leaves are resiliently deformable and can be collapsed onto themselves and onto the hub. The leaves can be retained in their collapsed condition by a packaging cover and subsequently by the grip of a medical practitioner.Type: GrantFiled: February 20, 2003Date of Patent: February 15, 2005Assignee: Becton, Dickinson and CompanyInventors: William G. Saulenas, Volker Niermann, Bradley M. Wilkinson

Publication number: 20040236287Abstract: A shielding medical device includes a needle cannula, a hub, a release element, a needle shield, and a biasing member. The hub has a proximal end, a distal end, and a passageway in fluid communication with the needle cannula. The distal end of the hub supports the needle cannula. The release element is fixed to the hub. The needle shield is hollow and has a proximal end, a distal end, and a pair of wings extending laterally from opposing sides. The proximal end of the needle shield is removably secured to the release element. The needle shield is axially movable with respect to the needle cannula from a first position in which the needle cannula is exposed to a second position in which the needle cannula is shielded within the needle shield. The biasing member is used to move the needle shield from the first to second positions.Type: ApplicationFiled: May 23, 2003Publication date: November 25, 2004Applicant: Becton Dickinson & CompanyInventors: Kirk D.
