Ampoule Syringes TRIZ Cases

The shell is sterilized before the electronic insert is assembled, separating heat-sensitive parts while venting and stepped interfaces support dosing precision.

BFS vials combine filling, sealing, and sterile barriers with NFC checks to verify injectors and limit reuse-related infection risk.

Sprayed non-reactive silicone oil is heated during autoclave sterilization to spread uniformly inside syringe barrels and prevent scratches or foreign matter.

An insertable reservoir unit uses an abutment surface to compress the reusable drive spring in one step without moving the stopper.

A pusher sleeve and elastic clips release the reservoir after needle-cover extension, reducing separation force and handling steps.

An elastically deformable cap covers the needle during reservoir detachment, reducing accidental contact in reusable injectors.

Distinct dosing and dispensing click teeth reduce manual dispensing force while adding audible and tactile feedback in a compact injection mechanism.

A slidable stopper seals components in a syringe barrel or cartridge during storage, then opens a channel for reliable reconstitution.

Opposing sliders cancel combined momentum during high-pressure liquid injection, reducing recoil motion and subject discomfort.

Inclined guide members and a spring-loaded ejector support secure, rotation-free cartridge loading for users with limited motor skills.

Sterile films and a piercing member create an aseptic drug pathway, reducing terminal sterilization needs and assembly complexity.
