Abstract
To provide a plastic adapter that includes a plastic cap and can be safely applied to the closed system drug transfer device. Provided is a plastic adapter attached to a pharmaceutical container to which a plastic cap is attached, and the adapter includes a top surface portion having a fitting portion at the center thereof, and a cylindrical skirt portion extending downward from an outer periphery of the top surface portion and opening at a lower end, in which the fitting portion includes a lip and an intermediate tube extending downward from the lip, and the fitting portion fits to a medical instrument used for a closed system drug transfer device.
Claims7
A plastic adapter (E) attached to a pharmaceutical container (A) to which a plastic cap is attached, the adapter (E) comprising:
- a top surface portion (E1) having a fitting portion (E11) at the center thereof;
- and
- a cylindrical skirt portion (E2) extending downward from an outer periphery of the top surface portion (E1) and opening at a lower end,
- wherein the fitting portion (E11) includes a lip (E112) aand an intermediate tube (E113) extending downward from the lip (E112), and
- the fitting portion (E11) fits to a medical instrument (F) used for a closed system drug transfer device.
A closed system drug transfer device comprising:
- a plastic cap (C) attached to a pharmaceutical container (A), which includes a top surface portion (C1) having an opening (C10) at the center thereof, a cylindrical skirt portion (C2) extending downward from an outer periphery of the top surface portion (C1) and opening at a lower end, and an inner cover (C3) provided inside the skirt portion (C2), in which a coefficient of friction between the inner cover (C3) and a rubber stopper (B) is higher than a coefficient of friction between the inner cover (C3) and the cap (C);
- and
- a plastic adapter (E) attached to the plastic cap (C), which includes a top surface portion (E1) having a fitting portion (E11) at the center thereof, and a cylindrical skirt portion (E2) extending downward from an outer periphery of the top surface portion (E1) and opening at a lower end, in which the fitting portion (E11) has a lip (E112) and an intermediate tube (E113) extending downward from the lip (E112), and the fitting portion (E11) fits to a medical instrument (F) used for the closed system drug transfer device.
