Publication number: 20180133451Abstract: Levers (30) are connected to a base end portion (13) of a male luer via a base (15). Each lever includes a locking portion (31) and an operating portion (35). A locking claw (32) protrudes from each locking portion toward the male luer. A lock ring (8) is provided opposing inner surfaces of the operating portions. The lock ring is movable between a first position at which the lock ring is located close to the base and a second position at which the lock ring is located away from the base. When the lock ring is at the first position, the levers are pivotable such that the locking claws move away from the male luer. When the lock ring is at the second position, the lock ring restricts the levers from pivoting such that the locking claws move away from the male luer.Type: ApplicationFiled: May 11, 2016Publication date: May 17, 2018Inventor: Masahiko TAKEUCHI

Publication number: 20180064923Abstract: A male luer (10) is surrounded by a hood (20). A lever (30) is connected to a base end portion (13) of the male luer via a base (15). The lever includes a locking portion (31) and an operating portion (35). A locking claw (32) protrudes from the locking portion toward the male luer. The locking portion is disposed in a cut-out (23) that is formed in the hood. The lever is elastically pivotable so that when an outer surface of the operating portion is pressed, the locking claw moves away from the male luer. When viewed along a central axis (3a), a connector main body (3) has a major axis (15a) in the direction in which the male luer opposes the lever.Type: ApplicationFiled: February 17, 2016Publication date: March 8, 2018Inventor: Masahiko TAKEUCHI
