AI Technical Summary

Technical Problem

In existing drug delivery devices, the drive assembly of the stop part is prone to instability during rotation and extension, resulting in inaccurate drug delivery and imbalance of external torque.

Method used

The telescopic stop actuator drive assembly, through the combination of anti-rotation guide and linear stabilizer, ensures stable propulsion of the distal shaft within the drug reservoir. The combination of anti-rotation guide and linear stabilizer prevents the distal shaft from rotating relative to the housing, and the linear stabilizer prevents axial movement of the proximal shaft in the proximal direction, thus achieving stable telescopic extension and retraction of the distal shaft.

Benefits of technology

This invention achieves stable drive of the stop part in the drug delivery device, reduces the influence of external torque, ensures accurate drug delivery, and maintains the balance and stability of the device during drug delivery.
