Infusion Syringes TRIZ Cases
- Multi-Chamber Syringe With Nested Fluid Paths for Excess Saline Control
A dual-plunger, multi-chamber syringe separates medication and saline paths to reduce excess fluid delivery in a compact profile.
- Injection Device Dose Setting with Sequential Plunger Projections
A movable dose setting member engages sequential plunger projections to improve small-dose accuracy while supporting air-bubble expulsion.
- Filtering Needle Seal Plug Blocks Reinsertion After Use
A held seal plug seals around the withdrawn needle path, blocking reinsertion and preventing contaminated payload administration.
- Syringe Stopper and Plunger Rod Support for Misalignment Sealing
This syringe case uses support disks and flexible regions to limit plunger misalignment, reduce stopper stress, and maintain sealing.
- Syringe Dose and Position Measurement with Plunger Travel Sensors
Rotary and inertial sensors track plunger travel and injection data, improving measurement precision and real-time training feedback.
- Medical Device Actuation Detection with Force and Touch Sensing
A force and touch detector replaces acoustic or vibrational sensing to improve medical device actuation reliability.
- Flexible Tubular NIR Device with Injection Needle for Tumor Therapy
Flexible tubing combines fluid injection and NIR irradiation for minimally invasive tumor treatment.
- Vacuum-Controlled Syringe Loading for Toxic Medication Handling
Vacuum-driven syringe loading reduces toxic medication exposure and repetitive-motion injury.
- Medical Injection Device Float Mechanism for Automatic Gas Evacuation
A float opens a dedicated evacuation path when gas is present, reducing purge time, liquid waste, and dosage errors.
- Medical Injection Device Automatic Gas Evacuation via Purge Valve
Automatic gas evacuation purges injection devices for accurate dosing and less liquid waste.
