<P>PROBLEM TO BE SOLVED: To provide a syringe cartridge that is sufficiently robust to be used in autoinjectors that generate injection forces sufficient to deliver viscous medicaments. <P>SOLUTION: The syringe cartridge includes a syringe 200, a forcing mechanism 300, and a casing 400. The casing 400 of the syringe cartridge includes a collapsible portion 430 and a fixed portion 460. Advantageously, the collapsible portion 430 of the casing 400 collapses within the fixed portion 460 of the casing 400 as the syringe 200 is driven through its stroke within the syringe cartridge. As the collapsible portion 430 collapses within the fixed portion 460, the length of the syringe cartridge is effectively reduced, which, in turn, allows use of a shorter plunger 13 and thereby facilitates construction of a more compact autoinjector. <P>COPYRIGHT: (C)2010,JPO&INPIT |
