Abstract
An injection device comprising an incremental clicking mechanism providing the user with an indication of the number of doses being set. For handling different types of medicaments having different dose volumes in the same type of injection device it is beneficial to provide an additional clicking means which is easy changeable. In this way different dose volumes can be dispensed by the same type of injection devices simply by utilizing different clicking means. The clicking means is preferably a curved track provided between the dose setting member and a non-rotatable clicker element.
Claims10
An injection device having a housing accommodating a cartridge containing medicine sufficient for a number of dosed injections, which doses are injected by advancing a piston rod forward inside the cartridge, comprising:
- a dose setting and injection mechanism, comprising an incremental feedback mechanism,
- a rotatable dose setting member operational coupled to the dose setting and injection mechanism for setting up a dose to be injected, and
- an injection button operational coupled to the dose setting and injection mechanism and by which the dose setting and injection mechanism can be activated for advancing the piston rod forward to press out the set dose through a conduit connected to said cartridge,
- wherein,
- an additional clicking means is provided between the rotatable dose setting member and a non-rotatable clicker element, and wherein the additional clicking means provides incremental clicks corresponding to a dose volume.
