Ampoule Syringes TRIZ Cases
- Pre-filled Syringe with Integrated Oxygen Absorber
An integrated oxygen absorber inside the syringe body removes headspace gas, extending shelf life without adding external packaging complexity.
- Braided Sleeve Needle Shield Remover Friction Grip
A tubular needle shield remover uses a braided sleeve to create a friction fit for reliable grip.
- Injection Device Holding Means Immobilize Piston Rod
Axially fixed holding means immobilize the piston rod via static friction, preventing medicament leakage without requiring precise manufacturing tolerances.
- Medical Delivery System Coding Mechanism for Misuse Prevention
Redundant geometric coding prevents incorrect container attachment, resolving the reliability versus complexity trade-off in medical delivery systems.
- Angled Needle Fluid Dispenser for Compact Wearable Injection
An angled needle configuration reduces device height below the needle length, resolving bulk constraints in wearable injection systems.
- Pharmaceutical Injection Device Needle Removal Reminder
A pharmaceutical injection device controller displays a needle removal message when the device powers off.
- Two-Component Syringe Attachment for Secure Hold
A two-component syringe attachment uses a deformable material to engage recesses on the cartridge protrusion.
- Movable Shield for Compression Syringe Preventing Needle Sticks
Segmented shield design transitions from retracted to extended position, eliminating accidental needle sticks during post-use handling.
- Flexible Impact Portion Dampens Torque Peaks in Injection Device Clutch
A flexible impact portion absorbs torque peaks within the clutch assembly of a wind-up injection device.
- Disposable Skin Piercing Assembly with Automatic Disabling Mechanism
A disposable assembly integrates a skin piercing element with an automatic disabling mechanism to prevent reuse after actuation.
- Offset Dual-Axis Injection Device Drive Assembly
Offset dual-axis arrangement positions the drive shaft around a secondary longitudinal axis to create internal volume for additional components.
- Injection Device Release Latch Mechanism for Needle Retraction
A release latch member interrupts force propagation to enable automatic needle retraction after dose delivery.
- Pivoting Needle Holder for Auto-Injector Clogging Prevention
A pivoting needle holder retracts the injection needle away from the medicament cartridge during storage to maintain operational readiness.
- Dispensing Speed Control Mechanism for Injection Device
Friction means regulate drive member rotation in an injection device to control dispensing speed.
- Integrated Pen Needle Cover with Lockout and Sterility Barrier
An integrated cover merges shielding, handling, and lockout functions to prevent accidental reuse without adding packaging complexity.
- Syringe Plunger With Vibration Activator for Acoustic Feedback
A syringe plunger uses a swinging arm body to generate acoustic signals during fluid dispensing.
