Infusion Devices TRIZ Cases
- Medical Device Clamp with Gravity-Assisted Ratchet
Spring-loaded pawls engage a pole while gravity amplifies clamping force, eliminating manual threading errors.
- One-Time Priming IV Extension Set with Flow Reversal
A one-time priming IV extension set uses a slide clamp to reverse fluid flow through a multi-tubing connector for simultaneous branch priming.
- Nasal Catheter System for Non-Invasive Cerebral Cooling
A nasal catheter system delivers cooled liquids through the nasopharynx to reduce cerebral temperature.
- Drip Device Piston Sealing Mechanism for Contamination Prevention
A drip device piston mechanism uses a plug to block the drip port, preventing external contamination while avoiding spray head deformation.
- I.V. Pole Clamp with Security Screw for Bed Transport
A U-shaped clamp with a security screw locks an I.V. pole to a hospital bed mounting plate, preventing detachment during transport.
- Vial Gate With One-Way Valves For Hemodialysis Drug Delivery
One-way valves in the vent and delivery lumens enable direct vial connection, eliminating syringe transfers that cause contamination.
