Description
Technical Parameters
Premium 4ml Dual-Chamber Cartridge Manufacturer | Optimedvo
As advanced biologics, high-molecular peptides, and highly unstable lyophilized powder formulations dominate the drug development pipeline, traditional reconstitution methods no longer suffice. Manual vial-to-syringe transfers invite contamination risks, dosing inaccuracies, and loss of bioactivity. Optimedvo addresses these critical clinical and commercial pain points directly with our proprietary 4ml Dual-Chamber Cartridge system.
Engineered for high-viscosity, large-volume therapeutics, this all-in-one primary packaging solution integrates secure drug storage and instant, closed-system mixing within a single sterile environment. By seamlessly pairing with our cutting-edge A/B/C 3-stage rotational step-lock injection pen, this system establishes physical barriers that eliminate premature injection and operational errors, offering pharmaceutical firms a truly foolproof drug delivery platform.
Core Technological Innovation: The A/B/C 3-Stage Rotational Step-Locking Mechanism
The core of our 4ml Dual-Chamber Cartridge injection pen system relies on a stepped multi-depth rotational interlocking mechanism that guides patients safely through a synchronized workflow:
【Stage A】Safe Reconstitution Lock
Rotating the cartridge holder to Stage A precisely drives the internal mechanism, forcing the liquid solvent through the middle bypass channel into the powder chamber. This ensures slow, quantitative, and gentle mixing, successfully preventing protein denaturation or excessive foaming caused by sudden high pressure.
【Stage B】Precise Priming Lock
Advancing to Stage B locks the formulation chamber volume, guiding the patient to perform vertical priming. This eliminates air bubbles and prevents any premature drug waste, ensuring accurate dosing.
【Stage C】Precise Injection Lock
Rotating to Stage C completely locks the holder to the pen body, fully engaging the high-precision dose selector at the dial end (supporting large, distinct 0-50 unit adjustment) for a smooth, low-force, and ultra-precise injection.

Why Partner with Optimedvo? A Verified B2B Advantage
Navigating global regulatory pathways requires more than just premium hardware-it demands a trusted manufacturing partner who understands container closure integrity (CCI) and combination product compliance. As a dedicated medical device manufacturer, Optimedvo offers end-to-end integration support to streamline your combination product (Device + Drug) co-development pipelines.
Instant, Closed-System Reconstitution: Enables fully enclosed mixing right before injection, completely shielding sensitive macromolecules from environmental degradation and securing 100% drug efficacy.
Exclusive Rotational Step-Locking for Foolproof Operation: Replaces error-prone "push-to-mix" designs with a physical "rotate-click-confirm" sequence. This drastically mitigates clinical and home-care operational risks.
High-Capacity 4ml Specification for Diverse Market Needs: Specifically tailored to meet emerging market trends for high-concentration, large-volume injectables, giving your formulation an immediate competitive edge.
Medical-Grade Material Integrity: Built using high-purity Type I borosilicate glass for the cartridge body to guarantee optimal drug compatibility and minimal extractables/leachables.
