AI Technical Summary
Technical Problem
Existing drug delivery devices using coil and spring structures face limitations such as a linear relationship between force and displacement, requiring excessive energy input and increased spring forces for higher viscosity drugs, and lack flexibility in spring design.
Method used
A drug delivery device with a plunger biased by a plunger biasing member that rotates and translates linearly, incorporating a plunger guide with a cam and cam follower mechanism, allowing for flexible spring design and reduced part complexity.
Benefits of technology
The device provides efficient drug delivery with reduced energy input, lower spring forces, and simplified design, facilitating self-administration and caregiver administration of drugs like peptides and antibodies.
