Patent number: 11820539Abstract: A manifold for control of fluid and/or vapor flow between a container and a pump cartridge for a compounder system is provided. One or more manifolds may be disposed in a magazine configured to secure and align the manifolds with a plurality of ports in the cartridge. Each manifold may include a needle having forward and rear openings to a central bore. A needle housing may include a slot configured to receive a push rod for actuating the needle forward and backward. In a forward, engaged position, the openings in the needle may be disposed on opposite sides of a sealing member of the manifold to form a fluid pathway through the manifold. In a rearward, disengaged position, both the forward and rear openings in the needle may be disposed on the same side of the sealing member to prevent fluid and vapor from flowing through the manifold.Type: GrantFiled: November 3, 2022Date of Patent: November 21, 2023Assignee: CAREFUSION 303, INC.Inventors: Ray P. Feith, Vincent Fuji Wang, Neil Quitoviera, George Michael Mansour, Christopher J. Zollinger, Matthew Quach

Publication number: 20230218882Abstract: Needleless connectors are described. An example needleless connector includes a housing and a compressible valve. The housing may define an internal cavity and may include a body section having a first port and one or more internal contact tabs and a base section having a valve mount and a second port. The compressible valve may be disposed within at least a portion of the internal cavity and be movably retained within the housing. The compressible valve may include a flange portion for securing the compressible valve within the housing. A central longitudinal axis of the housing may be defined by a coaxial arrangement of the first and second port. The one or more internal contact tabs may be arranged to contact an outer side surface of the flange portion such that a radial force substantially orthogonal to the central longitudinal axis is provided for securement.Type: ApplicationFiled: February 24, 2023Publication date: July 13, 2023Inventors: George Michel MANSOUR, Christopher J. ZOLLINGER, Matthew QUACH, Jonathan YEH
