Patent number: 7837659Abstract: A luer connector assembly is provided for enhancing the frictional engagement between medical devices such as syringes and needle assemblies. The assembly needle includes a female luer fitting having a passageway and a relatively soft, resilient member bounding the passageway. The passageway is also bounded by the body of the fitting, which is harder than the soft, resilient member. A male luer fitting inserted into the passageway engages both the soft, resilient member and the body of the female luer fitting. A method of manufacturing such a connector assembly is further provided. A first material is injected into a mold to form the body of a female luer fitting, the fitting including a passageway and a recess extending into the body. A second material is then injected such that it extends into the recess and bounds the passageway. The second material, when cool, is softer than the first material.Type: GrantFiled: July 10, 2008Date of Patent: November 23, 2010Assignee: Becton, Dickinson and CompanyInventors: Charles F. Bush, Jr., Gene Fleischer, Charles G. Hwang, C. Mark Newby

Patent number: 7717881Abstract: A medical device for use with a fluid transfer device includes a hub having an open proximal end with a frusto-conically-shaped cavity therein, a distal end and a passageway therethrough. The cavity is part of the passageway. A release element in the passageway of the hub is positioned to block fluid-tight engagement of the frusto-conically-shaped tip with the cavity of the hub. Structure is provided to release at least part of the release element, upon application of a proximally directed force on the hub, to allow the abrupt fluid-tight engagement of the tip and the cavity in the hub.Type: GrantFiled: January 4, 2007Date of Patent: May 18, 2010Assignee: Becton, Dickinson and CompanyInventors: Richard Caizza, William N.

Publication number: 20090247962Abstract: A needle assembly is disclosed, which includes a needle hub, a metal cannula and a plastic tip. The needle hub defines a fluid flow path therethrough. The metal cannula is supported on a distal end of the needle hub, where the metal cannula defines a fluid flow path into the distal end of the needle hub. The plastic tip member is connected to a distal end of the metal cannula, where the plastic tip member defines a fluid flow path into the distal end of the metal cannula. Plastic tip further includes a channel groove that runs along the length of the plastic tip to allow fluid to flow into a distal end of the metal cannula. Additionally, the plastic tip member is configured to pierce a septum of a vial.Type: ApplicationFiled: March 23, 2009Publication date: October 1, 2009Applicant: Tyco Healthcare Group LPInventor: Eugene E.

Patent number: 7544189Abstract: A needle and hub assembly for an automatic injector and a method for making the needle and hub assembly. The needle and hub assembly comprises a cap or skirt, a forward surface of which is interposed between and reinforced by first and second engaged hub portions. A needle is received in a contiguous channel formed in the two hub portions. The method for making the assembly comprises molding the first hub portion, placing the cap over the first hub portion, inserting the needle into a channel in the first hub portion, and then overmolding or otherwise forming the second hub portion on the exterior of the cap such that it is engaged with the first hub portion. An assembly created by this “two-shot” process can be used to seal a relatively large opening, and supports the needle more effectively than a conventional assembly.Type: GrantFiled: March 11, 2004Date of Patent: June 9, 2009Assignee: Meridian Medical Technologies, Inc.Inventor: Steven M.

Patent number: 7303550Abstract: A disposable syringe includes a tubular needle seat inserted into a barrel for fixing a needle cannula. The needle seat has an axially extending cavity with a radially yieldable catch disposed therein. A plunger is movable in the barrel, and has an engaging head defining a rearwardly facing shoulder wall which is retained by the catch when the engaging head is extended into the cavity by a pushing force applied to the plunger. The barrel defines friction diminishing regions such that when the needle seat is moved past the friction diminishing regions to be placed to a disposal position, friction between the needle seat and the barrel is diminished, thereby facilitating a subsequent pulling action of the plunger for retracting the needle cannula into the barrel.Type: GrantFiled: October 28, 2004Date of Patent: December 4, 2007Inventors: Ming-Jeng Shue, Deborah Huang, Phillip Shue
