Patent number: 7935103Abstract: A syringe assembly comprises a syringe barrel having an elongated body defining a chamber for retaining fluid, an open proximal end, a distal end and a frusto-conically shaped tip extending from the distal end and having a passageway therethrough in fluid communication with the chamber. The chamber has an inside diameter of at least 13.5 mm. A stopper is in fluid-tight engagement inside the barrel. An elongated plunger rod extends proximally from the stopper through the open proximal end of the barrel. A flange is positioned at the proximal end of the plunger rod. The flange is shaped and positioned to limit the distal motion of the plunger rod in the barrel by contacting the proximal end of the barrel. A tip cap is releasably connected to the tip for sealing the passageway and the chamber contains injectable liquid.Type: GrantFiled: January 8, 2010Date of Patent: May 3, 2011Assignee: Becton, Dickinson and CompanyInventors: Robert B.

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.

Patent number: 7575570Abstract: A syringe assembly having passive disabling structure includes a barrel and a plunger rod assembly. The plunger rod assembly includes a plunger rod and a stopper connected by an indexing locking element. The number of strokes of the syringe plunger before the stopper is locked into the barrel rendering the syringe assembly unusable is determined by the number of detents on the plunger rod and stopper which engage the locking mechanism. Upon completion of the final delivery stroke, any attempt to withdraw the plunger rod from the barrel will cause the locking element to engage the barrel and trap the stopper in the barrel preventing further use of the syringe.Type: GrantFiled: January 25, 2008Date of Patent: August 18, 2009Assignee: Becton, Dickinson and CompanyInventor: Aaron Barere

Patent number: 7115114Abstract: A medical device having a releasable retaining includes needle cannula connected to a hub having an open proximal end with a frusto-conically shaped cavity therein. The cavity is part of a passageway through the hub which is in fluid communication with the lumen of the needle cannula. A retaining element is releasably connected to the hub. The hub includes an aperture and at least one protuberance projecting into the aperture for engaging the frusto-conically shaped tip of a fluid delivery device. The protuberance is shaped to offer less resistance to hub movement in a direction of engagement than in a direction of disengagement with the tip. The retaining element is connected to the hub so that when the hub is engaged to the tip, the force required to disengage the retaining element from the tip is greater than the force required to disengage the retaining element from the hub.Type: GrantFiled: May 2, 2003Date of Patent: October 3, 2006Assignee: Becton, Dickinson and CompanyInventor: Richard J.
