    Abstract: A pen-type injector is improved so that a user may select a delivery dose of a medicinal product from a multidose cartridge. The injector includes a housing, the cartridge containing the medicinal product retained within the housing, a piston rod, a dose selecting member to select the dose of the medicinal product to be expelled, and a drive member to expel the selected dose of the medicinal product. The housing is formed unitary so that the dose selecting member and the drive member are moveably retained within the housing. The injector may include a ratchet associated with an insert to ensure the piston rod only rotates in a single direction through the insert, a button located on the drive sleeve, and a clutch which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.

    Abstract: The present disclosure is directed to a dose setting mechanism that may be used with a drug delivery device. The dose setting mechanism may include an inner body having a helical thread along an outer cylindrical surface of the inner body, and a drive sleeve for driving a piston rod in an axial direction, the drive sleeve positioned within at least a portion of the inner body. The dose setting mechanism may further include a dose dial sleeve rotatably engaged with the helical thread of the inner body and a dial grip connected to the dose dial sleeve and releasably connected to the drive sleeve. Further when a dose is set, the dial grip is rotated so that both the dose dial sleeve and the drive sleeve rotate with respect to the inner body.
