  • Publication number: 20180311491
    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: 10004892
    Abstract: A needleless connector has a housing with an internal cavity having an interior surface, a port, an output flow channel, and a fluid flow path through the cavity between the port and the output flow channel. A collapsible valve is disposed within the cavity. The valve has one or more rings each having a surface that is in sealing contact with the interior surface of the housing. There are one or more notches formed in each of the one or more rings, and the flow path passes through one of the notches in each of the one or more rings.

  • Publication number: 20170296802
    Abstract: A needleless connector has a body having an internal cavity with a sealing ridge, a port, an output flow channel, and a fluid flow path between the port and output flow channel. The connector also has a collapsible valve disposed within the cavity. The valve includes a cylindrical wall having a center axis, an internal surface, and a shoulder configured to sealingly contact the ridge of the body, thereby blocking the fluid flow path. The valve also includes a head fixedly attached to the wall. The head has a smiley cut at a first angular position about the center axis and a continuous top surface that is generally perpendicular to the axis. The valve also includes a dimple formed in the internal surface of the cylindrical wall. The dimple extends around the internal surface over an angle.

  • Publication number: 20170290216
    Abstract: A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.

  • Patent number: 9370651
    Abstract: A female connector has a body with an internal cavity having a port and an internal surface. A collapsible valve is disposed within the internal cavity. The valve has a head with an external surface, wherein the head is in sealing contact with the internal surface of the internal cavity at a first location separated from the port so as to create a primary seal and at a second location proximate to the port so as to form a secondary seal when the female connector is not mated with a compatible male connector. The valve also has a neck coupled to the head proximal to the primary seal. The neck has a smiley cut. The valve also has a base portion coupled to the neck proximal to the smiley cut.

  • Publication number: 20160067437
    Abstract: An infant nasal interface mask for use with a nasal continuous positive airway pressure (nCPAP) system including a mask body and a base. The mask body forms a cavity and is defined by a leading portion, an intermediate shell portion, and a trailing portion. The leading portion terminates in a leading edge forming an aperture open to the cavity and having a generally triangular shape for placement over a patient's nose. The trailing portion includes a bellows segment characterized by an increased flexibility as compared to a flexibility of the intermediate shell portion. The base extends from the trailing portion opposite the leading portion and forms at least one longitudinal passage extending through a thickness of the base and fluidly connected to the cavity. The intermediate shell portion is laterally pivotable relative to the base via the bellows segment.
