摘要： A medication injection pen is provided comprising a housing (218), for housing a dose set knob (220), a leadscrew (226), a driver (224), a setback member (222), and a dose stop member (228). The dose set knob (220) is rotatable with respect to said housing (218) to set a desired injection dose, and comprises at least one internal thread (291). The leadscrew (226) includes a thread element by which it is advanceable in a first direction via a corresponding thread engagement, said first direction being that which expels medication from a cartridge (36). The driver (224) is rotationally fixed to said leadscrew (226) for preventing relative rotation therebetween, said driver (224) being rotatable in a first direction to rotate and advance said leadscrew (226) in said first direction. The setback member (222) is rotationally fixed to said driver (224) for preventing relative rotation therebetween. The dose stop member (228) is rotationally coupled to said setback member (222) and comprises an external thread (290) in threaded engagement with said internal thread (291) of said dose set knob (220), said dose stop member (228) being axially movable relative to said dose set knob (220) when said dose set knob (220) is rotated relative to said setback member (222), and wherein axial movement of said dose stop member (228) limits the user from setting a dose that is greater than an injectable volume of medication remaining in the cartridge (36).

摘要： A medication injection pen (11) includes a housing (1) and a dose set knob (2) rotatable with respect to the housing (1). A brake assembly (68) is disposed in the housing (1) and has a ratchet member (43). A driver (21) includes at least one external tooth (57) engaging the ratchet member (43). The engagement between the ratchet member (43) and the at least one external tooth (57) substantially prevents the driver (21) from rotating with respect to the dose set knob (2) during dose setting and dose correcting. The engagement between the ratchet member (43) and the at least one external tooth (57) allows the driver (21) to rotate with the dose set knob (2) during an injection.

摘要： A medication injection pen (51) includes a housing (1) and a dose set knob (2) having at least one internal tooth (22). A brake member (5) has a plurality of axially extending splines (52). A driver or setback member (9) includes at least one external tooth (92) engaging the at least one internal tooth (22) of the dose set knob (2) and at least one ratchet arm (96) engaging the plurality of axially extending splines (52). The driver (9) is prevented from rotating with the dose set knob (2) while moving axially with the dose set knob (2) during dose setting and dose correcting, and the driver (9) rotates with the dose set knob (2) during an injection.

摘要： A stopper adapted for attachment with a plunger rod for use within a syringe barrel is disclosed. The stopper includes a main body defining an open rearward end and a closed front end. The open rearward end is adapted to receive a front forward end attachment portion of the plunger rod. The stopper also includes a core member integrally formed with said main body adjacent the closed front end. The core member includes a nose portion having a profile adapted to create a positive seal with an outlet opening of such syringe barrel.
