Abstract
An injection device comprising a housing and a dose setting mechanism including a dose setting element. Contrary to prior art injection devices, the dose setting element can only be set at a few different dose settings. This is established by forming the dose setting element as a rotatable dish concealed within the housing and having a number of projections projecting outside the boundaries of the housing through a slot in the housing. A dose is set by activating a projection which in addition provides the user with a tactile guidance. Usually one projection is provided for one dose setting limiting the number of doses to be set to the number of projections.
