  • Injection device drive with two gear patterns
    Patent number: 10987471
    Abstract: An injection device having a drive member with first and second gear patterns that are fixed relative to each other. The drive member is rotatable and translatable in first and second opposing axial directions. A plunger expels medicament from a cartridge when it is translated in an advancing direction. A dosage indicator indicates a set dosage. A first gearing arrangement operably couples the first gear pattern with the plunger wherein rotation of the drive member in a first direction translates the drive member in a first axial direction without movement of the plunger and translation of the drive member in the opposite axial direction drives the plunger in the advancing direction. A second gearing arrangement operably couples the second gear pattern with the dosage indicator and moves the dosage indicator to indicate an increase in the set dosage when the drive member is translated in the first axial direction.
