A fluid conduit has a housing with a body forming an interior and a proximal cavity within the interior. The housing has an outlet and a fluid path extending between the cavity and outlet. The conduit also has an entry channel and a contact surface. The entry channel extends through the housing distal to the cavity and has a radial longitudinal axis. The entry channel is offset from the fluid path such that the radial longitudinal axis of the entry channel does not intersect a longitudinal axis of the fluid path. This offset causes fluid entering the interior of the housing via the entry channel to initiate a swirl-like motion within the interior. A portion of the contact surface is distal to the cavity and intersects the radial longitudinal axis. The surface directs a portion of the fluid proximally into the cavity.

A fluid control component configured for controlling fluid flow through the hub of a catheter assembly during and after placement into the patient is disclosed. In one embodiment, the fluid control component comprises a body disposed within a cavity of the hub, the body being movable between a first position and a second position, wherein the body does not pierce a valve disposed in the hub when in the first position and wherein the body pierces the valve when in the second position. The body includes a conduit to enable fluid flow through an internal portion of the body when the body is in the second position, and a plurality of longitudinal ribs disposed on an exterior surface of the body. The longitudinal ribs can provide fluid flow channels between the valve and an external portion of the body when the body is in the second position.

Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.

Some embodiments disclosed herein relate to a medical connector with an internal cavity with an internal closure system having a dome valve configured to resist retrograde fluid flow caused by various sources, including patient activity and fluid administration activity. A proximal closure system with a seal member and a moveable plug are also located within the internal cavity.

Aspects of the present disclosure include a connector that is suitable for connecting medical suction tubing with at least two different types of fluid ports of a medical fluid collection system. In certain aspects, the connector includes a generally cylindrical body portion having a cylindrical outer surface extending generally parallel to a central longitudinal axis of the body portion, and an inner surface defining a primary conduit extending through the connector. At least one lateral closure wall extends radially outward from the outer surface of the body portion. At least one annular skirt wall extends longitudinally from the at least one lateral closure wall, including a first annular skirt wall that serves to receive an open mouth of a first fluid port having a relatively small diameter, and a second annular skirt wall that serves to receive an open mouth of a second fluid port having a relatively larger diameter.

A medical device includes a connector portion. The connector portion includes an inner cylinder connectable to another medical device having an elastic valve, a valve body against which the elastic valve is pressed from a distal end side due to connection of the inner cylinder and another medical device, and an outer cylinder disposed radially outside the inner cylinder, and the connector portion is configured to provide fluid communication between the connector portion and another medical device by moving the inner cylinder in an axial direction with respect to the outer cylinder in a state where the inner cylinder is connected with another medical device. The connector portion further includes an anchor that suppresses movement of the valve body with respect to the inner cylinder toward a proximal end.

A solution is proposed for closing a mouth (125) of a container (110) of a liquid (105). A corresponding closure (135) comprises a cap (205) having fixing means (315) for fixing the cap (205) to the container (110), a delivery port (321) for delivering the liquid (105) from the container (110), a valve member (215) in a closed position wherein the valve member (215) closes the delivery port (321), a cap suction conduit (339) for suctioning air into the container (110) during the delivering of the liquid (105) and a connector (327) for connecting to a delivery device (805) of the liquid (105), the connector (327) being in fluid communication with the delivery port (321), a slider (220) slidebly coupled with the cap (205), the slider (220) having a slider suction conduit (440) for suctioning the air into the container (110) during the delivering of the liquid (105) slidebly coupled with the cap suction conduit (339), and a frangible element (345) closing the cap suction conduit (339) or the slider suction conduit (440), wherein the closure (135) is configured to cause the delivery device (805) during the connecting thereof to move inwards the container (110), in a fixed condition wherein the closure (135) is fixed to the container (110), and thus moving the valve member (215) inwards the container to an open position, wherein the valve member (215) opens the delivery port (321), and moving the slider (220) inwards the container to break the frangible element (345), thereby putting in fluid communication the slider suction conduit (440) with the cap suction conduit (339).

A fluid control component configured for controlling fluid flow through the hub of a catheter assembly during and after placement into the patient is disclosed. In one embodiment, the fluid control component comprises a body disposed within a cavity of the hub, the body being movable between a first position and a second position, wherein the body does not pierce a valve disposed in the hub when in the first position and wherein the body pierces the valve when in the second position. The body includes a conduit to enable fluid flow through an internal portion of the body when the body is in the second position, and a plurality of longitudinally extending ribs disposed on an exterior surface of the body. The ribs provide at least one fluid flow channel between the valve and an external portion of the body when the body is in the second position.

Fluid channel sealing devices, frangible seals, fluid circuits, associated controllers and methods of using the same are provided for controlling fluid distribution using a reconfigurable blocking element having first and second portions to establish a first configuration free of any open channels such that fluid is prevented from flowing through the channel and a second configuration where the first and second portions are separated to establish an open channel and allow fluid to pass.

A connector system having for joining tubes having an overmolded or bonded connector or manifold incorporating specialized features. The overmolded or bonded connector includes a tubular body, an input portion, at least one output portion, an internal fluid passageway, and at least one specialized feature such as a valve or sensor integrally molded or embedded therein. The connection system may be pre-sterilized, disposable and made for single-time usage in a closed fluid handling system.
