Patent number: 8414560Abstract: 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: October 19, 2007Date of Patent: April 9, 2013Assignee: Becton, Dickinson and CompanyInventors: Charles F. Bush, Jr., Gene Fleischer, Charles G. Hwang, C. Mark Newby

Patent number: 7387615Abstract: A single use syringe assembly includes a barrel having a chamber for retaining fluid, an open proximal end and a distal end including an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A needle cannula having a lumen therethrough is connected to the elongate tip so that the lumen is in fluid communication with the passageway. An elongate needle shield having a longitudinal opening therein is hingedly connected to the barrel. A needle shield is capable of pivoting from an open position or a closed needle protecting position. The plunger including an elongate body portion and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel. Structure is provided for locking the plunger in the barrel by applying distally directed force to the plunger after fluid has been delivered from the chamber.Type: GrantFiled: October 2, 2003Date of Patent: June 17, 2008Assignee: Becton, Dickinson and CompanyInventors: Eduardo Pinto Coelho, Delmar Francisco Goncalves Da Silva, Amir A.

Publication number: 20070299395Abstract: A single use syringe and a plunger rod assembly for such a syringe are provided. The syringe includes features that cause the plunger rod to be locked with respect to the syringe barrel upon completion of an injection stroke. The locking device may include barbs for engaging the syringe barrel and relatively long, proximally extending legs. The legs include barbs for engaging the syringe barrel and end portions for engaging the plunger rod. The plunger rod assembly includes a recess defined by converging surfaces, the recess being displaced from the longitudinal axis thereof. A locking element that fits a smaller syringe can thereby be used in a larger syringe as well.Type: ApplicationFiled: September 7, 2007Publication date: December 27, 2007Applicant: BECTON, DICKINSON AND COMPANYInventors: Brian Pelkey, Gene Fleischer

Patent number: 5282961Abstract: A floating impeller assembly for use with an electromagnetic stator unit includes a stationary shaft with a magnetic rotor rotationally mounted on the shaft. An impeller unit is rotationally mounted on the shaft and a unitary retaining and clutch mechanism between the magnetic rotor and the impeller unit drives the impeller unit by means of rotation of the magnetic rotor. The magnetic rotor and the impeller float on the shaft facilitating reducing the noise, friction and wear, heretofore, present in prior art units. The floating impeller assembly is used within an aquarium filter for drawing water from the aquarium into the aquarium filter for filtration and discharge back into the aquarium tank.Type: GrantFiled: June 23, 1993Date of Patent: February 1, 1994Assignee: Willinger Bros., Inc.Inventors: Robert Ellis, Allan H.
