White Paper: Designing Auto-Injectors
For Multiple Drug Viscosities
The springs that control introduction of the surgical sharp, the delivery rate or dosage of the drug, and the automatic retraction of the needle are the most critical metal components of any auto-injector.
Proper design of the plastic housing and specification of the material and size of the springs for any single-drug auto-injector are essential, but those tasks become even more vital and complex if an OEM wants to repurpose that same device for multiple drugs and biologics with varying viscosities.
This white paper will provide an in-depth understanding of what OEMs need to know about designing springs and working with contract manufacturers to ensure they are effective.
