Ampoule Syringes TRIZ Cases

Decoupling driver components resets the spindle axially, reducing device complexity and manufacturing costs.

Replacing mechanical wear with contactless capacitive sensing, this arrangement resolves the trade-off between measurement precision and device complexity.

An automated driving module adjusts the pressurizing plunger speed to reduce patient pain from high pressure while maintaining consistent injection rates.

A drug reconstitution system uses a sensing arrangement to detect vial position before enabling fluid communication.

A rotationally-activated locking mechanism secures a pen injection system within an elongated inserter body.

Segmenting the injector pen, base station, and remote hub resolves complexity trade-offs while enabling automated compliance monitoring and auto-replenishment.

A plunger rod positioning member aligns the actuator with the stopper to accommodate container tolerance variations and ensure consistent initial contact.

A compliant spring member strains during attachment to provide tactile feedback for incompatible cartridge pairings.

A syringe design featuring a hollow body and coaxial movement mechanism that allows the needle cannula to move between two seats for easier operation.

An adapter with angled surfaces guides needle placement on syringes.

A reusable injector device uses constant force springs and damping mechanisms to drive syringe carriers for consistent medicament dispensing.

An override coupling prevents back-driving during setting, ensuring accurate dose delivery without complex locking mechanisms.

An annular mounting sleeve with biasing springs prevents premature activation by detecting needle shield contact during assembly.

Segmented container holder design prevents hazardous ejection of broken glass while maintaining needle shield integrity and simplifying manufacturing.

Segmenting the fill-finish assembly allows pre-sterilization of internal components before drug filling, eliminating terminal radiation damage risks.

A recess accommodates the needle tip while a locally thinner fluoropolymer film prevents protein adsorption and avoids needle breakage.
