  • Publication number: 20250101356
    Abstract: The culture insert container has a lower culture container having a bottom portion equipped with a porous membrane and a sidewall, and having an upper insertion fixture having a cylindrical sidewall that is inserted into said lower culture container. The cylindrical sidewall has a land arranged so as to protrude from a top end of the sidewall of the lower culture container at a location such as will cause a top surface of said porous membrane and a bottom end portion of the cylindrical sidewall which is inserted within the lower culture container to be maintained in a noncontacting state. A land is arranged at an outer surface of the cylindrical sidewall so as to cause a constant distance to be maintained between an inner surface of the sidewall of the lower culture container and the outer surface of the cylindrical sidewall.

  • Patent number: 11052235
    Abstract: 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.
