| 摘要 |
The invention refers to a handheld injection device comprising a housing (10; 340) containing a cartridge (20), a dose setting means (60, 70; 350) being operable in a first direction to set a desired dose to be dispensed, a piston rod (30) being adapted to cooperate with a piston so as to cause a set dose to be injected from the cartridge (20), and a first clicker component (100; 320), which is largely rotationally constrained to the housing (10; 340), and a second clicker component (80; 300), which is rotatable relative to the housing (10; 340) during dose dispensing. The clicker components (80, 100; 300, 320) are adapted to contact each other only at the end of dispensing of a set dose to thereby provide an audible and/or tactile first feedback to a user. The first clicker component (100; 320) is displaceable relative to the housing (10; 340) between a proximal dose setting position and a distal dose dispensing position. |

1. An injection device comprising
a housing (10; 340) containing a cartridge (20), a dose setting means (60, 70; 350) being operable in a first direction to set a desired dose to be dispensed, a piston rod (30) being adapted to cooperate with a piston so as to cause a set dose to be injected from the cartridge (20), and a first clicker component (100; 320), which is rotationally largely constrained to the housing (10; 340), and a second clicker component (80; 300), which is rotatable relative to the housing (10; 340) during dose dispensing, with the clicker components (80, 100; 320, 300) being adapted to contact each other only near the end of dispensing of a set dose to thereby provide an audible and/or tactile first feedback to a user,wherein the first clicker component (100; 320) is displaceable relative to the housing (10; 340) between a proximal dose setting position and a distal dose dispensing position. |
