Infusion Devices TRIZ Cases
- Two-Part Infusion Drip Chamber With Adhesive Grip Ring Joint
A rigid upper body and flexible lower body are adhesively joined to create a leak-proof grip ring that simplifies molding and maintains stable infusion flow.
- Needleless Connector Securement With Movable Bracket Access
A dual adhesive securement with a movable bracket stabilizes catheters and needleless connectors while improving access during saline workflows.
- Drip Chamber Float Switching for Continuous Multi-Bottle Infusion
A float-controlled drip chamber switches infusion bottles by liquid level, maintaining continuous flow and preventing air entry.
- Collapsible Valve IV Connector to Eliminate Flush Dead Space
A collapsible valve routes syringe medication into the main IV flow path, cutting dead space, flush volume, cost, and noise.
- Pivoting Catheter Securement for Stabilization and Maintenance Access
A swing-arm catheter securement stabilizes the cannula while pivoting away for site maintenance, reducing dislodgment, skin injury, and infection risk.
- Infusion Pump Housing With Single-Lock Pole Securing
A pivoting hook and flap share one lock to secure an infusion pump housing to an infusion pole with fewer locking steps.
- Siloxane-Modified Polycarbonate for Intralipid-Resistant Medical Parts
Functionalized siloxane improves aromatic polycarbonate intralipid resistance while preserving melt flowability for medical parts.
- IV Line Spool Restraint for Strain Relief and Catheter Protection
A spool-based IV line restraint absorbs pull forces and stores excess tubing to reduce snags, accidental catheter removal, and treatment disruption.
- Gravity-Fed Burette With Buoyant Valve for Consistent IV Flow
A buoyant shuttle valve and standardized gravity-fed burette improve IV flow consistency, reduce vein damage, and support hazardous drug delivery.
- Needle-Free Valve Grooves to Prevent Sleeve Stiction and Leakage
Grooves on the connector post cut sleeve friction so the elastomeric valve closes faster, reducing leakage and improving fluid delivery.
- Needleless Connector Folding Seal for Low-Stress Center Post Insertion
Molded recesses and lubricant replace razor-cut slits in needleless connector seals, reducing tearing risk and insertion friction.
- Blood Transfusion Kit With Filter Bypass for Emergency Switching
A dual-path transfusion kit switches between leukocyte filtration and a bypass route to speed emergency blood delivery while keeping normal use safe.
- Snap-Fit Fluid Connector Valve for Secure IV Line Coupling
A sleeve, arm, and biased post keep IV fluid connectors locked under force, block flow when disconnected, and reopen the pathway on reconnection.
- Infusion Drip Chamber Priming With a Movable Volume Adjustment Member
A movable adjustment member changes drip chamber volume to prime the infusion line faster and more easily than repeated manual squeezing.
- IV Pole Holder Structure for Shielded Secure Medical Item Support
A molded reusable holder secures IV bags, pacemakers, and probes on an IV pole behind an ether screen for stable, cleaner positioning.
