Patent ID: 8083711

Claim:
An injection device ( 1 ) comprising a housing ( 8 ), a piston rod that is separate element distinct from the housing and wherein the piston rod moves relative to the housing; a resilient member ( 7 ) adapted to provide a force in the axial direction of the injection device ( 1 ), the force being necessary for ejecting a dose from the injection device ( 1 ), and a dose setting member ( 2 ) operatively connected to a dose indicator barrel ( 4 ) positioned within the housing ( 8 ), the dose setting member ( 2 ) and the dose indicator barrel ( 4 ) being movable relative to each other and cooperating to set the dose to be ejected from the injection device ( 1 ), the dose indicator barrel ( 4 ) engaging a threaded portion of the housing ( 8 ), wherein the dose indicator barrel ( 4 ), both during dose setting and during injection, is adapted undergo a combined rotational and translational movement within the housing ( 8 ) and relative to the housing ( 8 ). a dose setting member ( 2 ) operatively connected to a dose indicator barrel ( 4 ) positioned within the housing ( 8 ), the dose setting member ( 2 ) and the dose indicator barrel ( 4 ) being movable relative to each other and cooperating to set the dose to be ejected from the injection device ( 1 ), the dose indicator barrel ( 4 ) engaging a threaded portion of the housing ( 8 ), wherein the dose indicator barrel ( 4 ), during dose setting, is adapted undergo a combined rotational and translational movement within the housing ( 8 ) and relative to the housing ( 8 ).
