International Classification:

A61M 39/24
A61M 39/26
A61M 39/10

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.

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.

International Classification:

A61M 39/26

US Classification:

251148, 251356

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 first dimple formed in the internal surface of the cylindrical wall. The dimple extends around the internal surface over an angle in the range of 90-270.

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 and a shoulder and defining an internal air space, wherein the shoulder is configured to sealingly contact the ridge of the body so as to block the fluid flow path, and a head fixedly attached to the wall, the head having first and second smiley cuts disposed on opposite sides of the head.
