A connector includes: a male connector portion; a first female connector portion; and a second female connector portion. The connector defines a flow path therein. The male connector portion is shaped to be connectable to a medical device female connector portion that is equal in shape to the first female connector portion. The male connector portion is shaped to not be connectable to a medical device female connector portion that is equal in shape to the second female connector portion.

A luer connector including a rigid housing having a first end and a second end. The housing further including a rigid tubular male portion at the first end, a rigid tubular female portion at the second end, and a longitudinal opening therethrough. The male portion is configured to be engageable with a female connector. The female portion is configured to be engageable with a male connector and to prevent the disengagement of the male connector from the female portion. In some embodiments, the female portion is configured to maintain a fixed rotational position when the male connector is being threaded therewith, but to rotate with the male connector once the male connector has become fully engaged with the female portion so as to prevent the male connector from becoming unthreaded from the female portion.

A catheter system may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The catheter system may include a connector coupled to the proximal end of the catheter adapter. The connector may include a T-connector. The catheter system may include a connector support device, which may be wedge-shaped to support the connector at an insertion angle.

The present invention provides a coronary artery bypass surgery treatment tool or the like including a flexible tube, a suction cup in which an opening portion is formed to communicate with the flexible tube and which is provided at a distal end of the flexible tube, a joint portion which has a suction path, a male connector which is provided in one of a proximal end of the flexible tube and a distal end of the suction path of the joint portion, and a female connector which is provided in the other thereof and is detachably connected to the male connector.

A connecting structure for medical use includes a male assembly (1) and a female connector (2) having a cylindrical configuration. The male assembly (1) includes a male connector (10) having a cylindrical configuration and a threadedly engageable cylinder (20) rotatably coupled to the male connector (10). A male luer portion (11) of the male connector (10) and a female luer portion (2a) of the female connector (2) are joined by turning the threadedly engageable cylinder (20) in a tightening direction when a female screw (21a) of the threadedly engageable cylinder (20) and an engageable protrusion (2c) of the female connector (2) are threadedly engaged with each other. The connecting structure for medical use further includes a loosening prevention mechanism (30) that prohibits rotation of the threadedly engageable cylinder (20) in a loosening direction with respect to the male connector (10) when the male luer portion (11) and the female luer portion (2a) are joined. The loosening prevention mechanism (30) includes ratchet teeth (31) formed in an inner periphery of the threadedly engageable cylinder (20), an elastic projection (32) formed in the male connector (10) and an engageable claw (33) protruded from a free end of the elastic projection (32) and engageable with the ratchet teeth.

A needle-free connector including a guiding base, a connecting base, a valve member, and a seal member is provided. The guiding base has a conduit, and the conduit extends downward along an axial direction. The connecting base is disposed on the guiding base and has a screw portion and a passage running through the screw portion. A chamber is formed between the guiding base and the connecting base, and the conduit and the passage respectively communicate with the chamber along the axial direction. The valve member is disposed between the guiding base and the connecting base, and is movably located in the chamber. The seal member is disposed at an end of the valve member far away from the conduit, and the seal member and the valve member are adapted to be connected into a whole in a manufacturing process.

This adaptor comprises a tubular body having a proximal region and a distal region, the proximal region configured to engage a distal tip of said drug delivery device and the distal region being configured to be connected to the connector. The distal region has a distal end delimiting a distal opening so as to permit introduction of the connector inside the distal region. The distal end is configured to be clamped to the connector when said connector is introduced inside the tubular body. The distal end comprises a deformable element having a free end which is configured to deform towards the proximal region when the connector is introduced inside the tubular body.

A retainer for connecting a pair of sanitary fittings each having a first end and a second end, the second ends each having a flanged portion, includes a first member having a through center aperture, the first member adapted to receive at least a portion of each of the flanged portions and a second member having a through center aperture and engageable over the first member, the second member adapted to provide a compressive force to sealingly connect the flanged portions when the first and second members are in an assembled configuration.

Luer connector including a primary Luer male connector, having a secondary female section extending from a top distal part of the primary Luer male connector back towards a proximal part thereof, the primary Luer male connector including a first inner fluid flow channel extending from a proximal end thereof to the secondary female section, the primary Luer male connector being configured to mate with a primary Luer female connector having a secondary male section including a second inner fluid flow channel.

Medical devices including a cap for a medical connector are disclosed. In some embodiments, the cap comprises a disinfectant, such as an antiseptic fluid and an insert configured to seal or partially seal the medical connector as it is engaged with the cap. In some embodiments the cap insert has a segment which is deformable under axially applied pressure as an end-user attaches the cap to the medical connector. In some embodiments this insert is configured to improve the exposure of antiseptic to the outer surface of the medical connector while minimizing exposure of the antiseptic inside the medical connector open lumen.
