| titleOfInvention |
An injection device for delivering a liquid drug |
| abstract |
The invention relates to a pre-filled injection device with a non-removable cartridge embedded in the housing structure and wherein the piston rod drive mechanism comprises a threaded piston rod which is moved helically in a nut secured to the housing structure. During assembly of the injection device it is possible to eliminate the air-gap between the plunger in the cartridge and the piston rod means by moving the nut element for the drive mechanism axially during assembly. In an alternative solution, the piston rod comprises a telescopic element which can slide axially in relation to the piston rod to obtain the zero position. |
