Disposable, Two-Step Auto-Injector

A disposable mechanical auto-injector designed for automated drug delivery with prefilled syringes (PFS).

Platform-Based Design

Compatible with 1.0 mL and 2.25 mL PFS formats, providing a flexible platform for a range of drug products.

Continuous Audible Feedback

Provides continuous audible feedback throughout the injection process, helping users monitor injection progress.

High Drug Compatibility

A constant-force spring mechanism provides consistent driving force throughout the injection process, enabling smooth and reliable delivery of drugs across a wide range of viscosities.

Simplified Final Assembly

Streamlined component design enables efficient and simplified final assembly for pharmaceutical manufacturers.

FTO Analysis Completed

Freedom-to-operate (FTO) analyses have been completed for China, the U.S., and Europe to assess potential patent risks.

Quick & Reliable Installation

The device comprises 14 components in total, including the PFS, with 11 injection-molded components and 2 springs. Its modular architecture separates the drug-containing and energy-storage functions, enabling quick and reliable two-step installation during pharmaceutical final assembly.

Cost-Effective Design

A simplified architecture with fewer components than conventional market devices helps reduce manufacturing and assembly costs.

Simple Two-Step Operation

Skin-activated two-step operation enables intuitive and user-friendly injection.
