Pressure Infusion TRIZ Cases
- Contrast Injection Device Alternating Saline and Contrast Phases
Alternating contrast and saline injection phases via a single device reduces extravasation risk while maintaining imaging quality.
- Rotating Compression Member for High Viscosity Medicament Delivery
A rotating compression member collapses a medicament reservoir to expel high viscosity fluid while reducing device complexity.
- Rigid Needle Insertion Mechanism for Drug Delivery Pump
A rigid needle insertion mechanism advances and retracts a drug delivery pump needle using integrated biasing members.
- Two-Stage Infusion Inserter with Rotatable Button and Spring Mechanism
A two-stage infusion inserter uses a rotatable button to drive a sliding component and needle carrier for automated cannula deployment.
- Telescopic Piston Rod Assembly for Compact Medicament Delivery
A telescopic piston rod assembly drives a medicament bung via nested segments that retract to minimize device length.
- Reservoir Compartment Adapter for Variable Infusion Reservoirs
Segmented adapters expand fixed compartments to hold larger reservoirs, eliminating the need for multiple infusion devices.
- Syringe Locator Prevents Infusion Device Disconnection
Stop teeth on the syringe prevent excessive rotation and disconnection, resolving reliability issues for users with limited dexterity.
