  • Publication number: 20240131257
    Abstract: A valve is disclosed that has a body with an inlet, an outlet, and a needleless access port coupled to the body. The access port has an interior space and is configured to be actuated by a needleless connector. The inlet is selectively coupled to the outlet through the interior space such that fluid entering the inlet entirely flows through the interior space to the outlet.

  • Patent number: 11820539
    Abstract: 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.

  • Publication number: 20230347131
    Abstract: Needleless connectors are described herein. A needleless connector includes a body, a valve element at least partially disposed within the body, and a base. The valve element includes a cylindrical portion having an outwardly extending flange at a distal end. The flange has a bottom surface with an outer area and an inner area. The base includes a rim having a top surface that is in contact with an outer area of the flange of the valve element, the rim defining a recess with a bottom surface separated from the top surface of the rim, and at least one support member having a top surface spaced apart from the top surface of the rim and configured to resist deformation of the flange toward the recess.

  • Publication number: 20230218882
    Abstract: 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.

  • Patent number: 11642284
    Abstract: A carousel configured to house a plurality of pump cartridges for a compounder system is provided. The carousel may include a plurality of cartridge pockets each having an extended portion that covers a portion of a cartridge and a bottom surface Shaving an extension with a recess. The bottom surface recess of each cartridge pocket may be shaped and sized to receive a needle housing of a pump cartridge in the cartridge pocket. A recess may be provided in the extended portion of each pocket that receives a protrusion that extends from a top surface of a backpack coupled to the pump cartridge to secure the pump cartridge in the cartridge pocket. The bottom surface recess may have an additional bottom surface that prevents actuation of the needle housing of the pump cartridge.

  • Patent number: 11622913
    Abstract: A compounder system having a vial puck configured for attachment to a vial containing a drug is provided. The vial puck includes features for facilitating uniform control of vials of various sizes in an automatic compounder system. The vial puck features may include a vial recess for receiving a vial of a particular size and securing the vial within the vial recess. The features may also include a cylindrical central portion, perpendicular extensions that extend from a top of the cylindrical central portion, a gear extending from the cylindrical central portion, and a sealing member disposed in the cylindrical central portion. The vial puck may include a cylindrical protrusion configured to press against a septum of the vial to form a seal between the vial puck and the vial. The sealing member may be configured to receive a needle of the compounder system therethrough to allow access to the vial.
