Pressure Infusion TRIZ Cases
- Medicinal Fluid Injector Flow Control via Rotating Knob and Elastic Tubes
Rotating knob actuates spring plates to compress elastic tubes, resolving dosage accuracy versus operator skill dependency in medical injection systems.
- Bi-stable Cannula Insertion and Retraction Mechanism
A bi-stable mechanism snaps a cannula in and out of skin using a single activation button.
- Infusion Device Fluid Line Fixation Mechanism
A fixation mechanism holds a longitudinal portion of the fluid line relative to the housing section for stable pumping interaction.
- Inserter Base Part Locking Mechanism for Medical Device Assembly
Protruding parts engage openings to prevent misplacement and contamination during medical device assembly.
- Needle Insertion and Retraction Mechanism for Drug Delivery
A single tension source drives a ratchet mechanism to extend and retract a needle, eliminating opposing restoring forces that increase user effort.
- Linear Shuttle Pump for Compact Drug Delivery
Opposing plunger components in a linear shuttle pump create a vacuum to extract liquid drugs, reducing device length compared to traditional plunger drives.
