Infusion Syringes TRIZ Cases
- Plug Delivery Device with Frustoconical Fluid Wetting Mechanism
A plug delivery device uses a frustoconical surface to wet and eject a plug through a lumen, resolving friction issues during void placement.
- Drug Delivery Cap Locking Mechanism Prevents Reuse
Resiliently biased locking member moves into a locking position upon cap removal to prevent full replacement on the housing.
- Slittable Cardiac Delivery Device Hub Shaft Integration
Integrating the shaft into the hub wall eliminates transitional jerk during removal, preventing cardiac tissue damage and lead dislodgement.
- Wearable Insulin Dispensing Unit with Protective Cannula Interface
A wearable insulin dispensing unit integrates a cannula interface for filling the reservoir without exposing the needle tip during normal wear.
- Syringe Pump Collar Sealing for Moisture Ingress Prevention
An intermediary collar with pressure equalization channels prevents moisture ingress into electromechanical pump components during operation.
- Lubricant-Free Syringe Stopper Insertion via Vacuum Assistance
Vacuum-assisted hybrid insertion device places lubricant-free stopper in syringe barrel, eliminating silicone contamination risks.
- Adipose Tissue Transplantation Device with Integrated Filtration
A hollow cylindrical chamber device uses a plunger filter to separate liquid from fatty tissue during suction and reinjection.
