    摘要: PROBLEM TO BE SOLVED: To provide a device in which a direct gear connection, i.e. a gearing for preventing further conversion of rotational motion to linear motion and of linear motion to rotational motion between an injection button and a piston rod, is established. SOLUTION: In the injection device for injection of a set dose of medicine from a cartridge, the dose is set by screwing a nut 13 upwardly along a threaded piston rod 4. A dose setting drum 17 and the injection button are moved axially by a distance larger than the axial movement distance of the nut. The dose setting drum carries on its cylindrical surface along a helix a scale of which a number corresponding to the set dose is shown in a window in a housing 1 of a syringe. The injection button is elevated over one end of the syringe. A gear wheel gear transmission 14, 16 is established between the nut and the injection button. COPYRIGHT: (C)2011,JPO&INPIT
