Publication number: 20180311491Abstract: 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: July 3, 2018Publication date: November 1, 2018Inventors: George Michel MANSOUR, Christopher J.

Publication number: 20170296802Abstract: 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.Type: ApplicationFiled: June 29, 2017Publication date: October 19, 2017Inventors: Matthew Quach, Christopher J.

Patent number: 9370651Abstract: 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.Type: GrantFiled: March 13, 2013Date of Patent: June 21, 2016Assignee: CareFusion 303, Inc.Inventors: Christopher J.

Publication number: 20160067437Abstract: 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.Type: ApplicationFiled: November 12, 2015Publication date: March 10, 2016Inventors: Christopher J.
