Patent number: 8763798Abstract: The present invention relates to a closure for filling and sealing receptacles containing medicinal fluids, a method for filling a receptacle with a medicinal fluid and sealing the receptacle. The closure used in the method comprises a mounting piece that may be attached to the receptacle and a connector piece that may be connected to a connector piece of a filling device. A closure body is arranged between the mounting piece and the connector piece, in which a closure piece for sealing the closure sits. The closure piece may be slid between a position sealing the closure and a position which opens the closure. The closure is sealed tight with a removable protective cap. The present method is characterized in that with the protective cap removed the receptacle is filled through the closure in a clean room, whereupon after filling, the closure is sealed by pressing the closure piece into the closure.Type: GrantFiled: January 22, 2008Date of Patent: July 1, 2014Assignee: Fresenius Medical Care Deutschland GmbHInventor: Michael Paul

Publication number: 20140180219Abstract: A needleless connector includes a hollow connector, a spring, and a switch assembly. The inner perimeter of the hollow connector forms a first annular wall and a second annular wall. The spring is disposed in the hollow connector. The switch assembly has a stop member and a guide tube connected to the stop member, the stop member being pressed between the annular block and the spring, the guide tube being disposed in the hollow connector, the external perimeter of the stop member forming a first annular portion against the first annular wall and a second annular portion against the second annular wall, a groove being disposed between the first annular portion and the second annular portion of the stop member, the groove being connected to the guide tube. Thus, the integral structure stability and good closing performance are achieved such that the outside air cannot leak into the connector structure.Type: ApplicationFiled: December 24, 2012Publication date: June 26, 2014Applicant: PACIFIC HOSPITAL SUPPLY CO., LTD.Inventors: Shih-Chi HO, Ming-Chung CHEN

Patent number: 8758302Abstract: In at least one embodiment, a hemostatic valve for use with a splittable introducer (10) is provided. The hemostatic valve (22) comprises a seal (24) molded in a first configuration of polymeric material and having two adjacent end surfaces (34,35). The seal is deformable from the first configuration into a second configuration. In the first configuration, the seal is substantially non-planer with the two adjacent end surfaces exposed. In the second configuration, the two adjacent end surfaces are unexposed so as to form a split extending through the seal.Type: GrantFiled: December 29, 2009Date of Patent: June 24, 2014Assignee: Cook Medical Technologies LLCInventor: Arman H. Valaie

Patent number: 8757590Abstract: A fluid flow connector including a housing assembly, having a first end and a second end arranged along a common longitudinal axis, and a resilient fluid flow conduit member having a forward end, disposed alongside the first end of the housing assembly, formed with a selectably closable slit and with at least one side opening. The resilient fluid flow conduit member is positionable in a closed position wherein the slit is closed but the at least one side opening is open and in an open position, allowing the slit to open and leaving the at least one side opening open, whereby when the resilient fluid flow conduit member is in the open position, the selectably closable slit and the at least one side opening each provide a fluid flow pathway between an interior of the resilient fluid flow conduit member and the first end of the housing assembly.Type: GrantFiled: March 18, 2010Date of Patent: June 24, 2014Assignee: Elcam Medical Agricultural Cooperative Association Ltd.Inventors: Ziv Naftalovitz, Amit Shlezinger, Tsachi Shaked, Avi Yogev, Tomer Gil

Publication number: 20140155838Abstract: A medical connector is described which is formed by a body having an inlet port, an outlet port through a male luer portion of the body, and a fluid path between the inlet port and the at least one outlet ports. A retractable post extends through the fluid path in the male luer sealing a tip of the male luer thereby closing the fluid path when the connector in not activated. There is a seal between the retractable post and the body that forms a fluid volume within a portion of the cavity. The fluid path passes through the fluid volume. When actuated, the retractable post is forced away from the tip of the male luer, thereby opening the fluid path through the medical connector and decreasing the fluid volume.Type: ApplicationFiled: February 4, 2014Publication date: June 5, 2014Applicant: Carefusion 303, Inc.Inventors: George M.
