  • Patent number: 8888750
    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.
