In some embodiments, at least one of the luer tip and the internal member can be axially moveable between a first closed position and a second open position relative to the other of the luer tip and the internal member. Further, the luer tip and the internal member can cooperate such that rotation of the luer tip in a first direction relative to the housing increases an axial displacement between the first open end of the luer tip and an end portion of the internal member. 19.-. (canceled)10. A closeable male luer connector comprising:a housing having a first end and a second end;the first end of the housing including a male luer tip having an opening in a first end thereof and a passageway through the male luer tip in fluid communication with the opening in the first end thereof; andan internal member extending into the passageway of the male luer tip toward the opening in the first end thereof, the internal member having an opening in a first end thereof and a passageway through the internal member in fluid communication with the opening in the first end thereof; the internal member is configured to translate axially within the luer tip from a first position in which the first end of the internal member cooperates with the first end of the male luer tip such the connector is in a closed state in that the connector is configured to substantially prevent fluid from flowing into or out of the opening of the male luer tip and a second position in which the connector is in an open state such that the ...

The fluid circuit of wherein said second connecting member comprises at least one engagement member.5. The fluid circuit of wherein said first connecting member comprises a receiving member for receiving said engagement member.6. The fluid circuit of wherein said at least one engagement member comprises a hook.7. The fluid circuit of comprising at least one slot for receiving ...

Catheter flush device, system, and methods

A flush device may be used to flush a catheter system. The flush device may include a housing, a proximal connector coupled to the housing, and a distal connector coupled to the housing. The flush device may include a first conduit disposed within the housing and extending between the proximal connector and the distal connector. The flush device may include a second conduit disposed within the housing and in fluid communication with the first conduit. The flush device may include a fluid reservoir, which may be disposed within the housing of the flush device. The flush device may include a pump that pumps fluid from the fluid reservoir, through the second conduit, and into the first conduit. The device may include a one-way valve, which may prevent fluid from flowing beyond the one-way valve toward the fluid reservoir.

RETENTION FEATURE FOR SOFT INTERFACE CONNECTION

A retention feature configured to provide interference between a threaded connection of a Luer access device and a separate device, wherein the Luer access device further comprises a septum that provides a soft interfaced between the two threadedly connected devices. The retention features of the instant invention are designed to provide the user with a tactile sensation of a tightening threaded connection, despite a soft interface between the interconnected devices. The retention features of the instant invention further prevent “spring back” and unintentional disengagement of the interconnected devices. 1. A luer access device , comprising:a body having an outer surface;an opening formed in the outer surface and configured to receive a needleless connector;a soft septum disposed in the opening and having a slit for receiving the needleless connector; anda set of threads on the outer surface, wherein a thread of the set of threads comprises a retention feature extending outwardly from the thread, wherein the retention feature is positioned to contact a portion of a complimentary set of threads on the needleless connector when threadedly coupled to the set of threads and provide increased resistance to unintentional disengagement of the threaded devices and a tactile feedback to a user of a tightened connection between the luer access device and the needleless connector, wherein the retention feature comprises a forward ramped surface and a rearward ramped surface, wherein the forward ramped surface is tapered at a first angle of incline along an axis that extends outwardly from the body, wherein the rearward ramped surface is tapered at a second angle of incline along the axis that extends outwardly from the body, wherein the second angle of incline is greater than the first angle of incline, wherein the first angle of incline provides a gradual increase in rotational torque required to threadedly couple the luer access device to the needleless connector.2. The ...
