Catheter TRIZ Cases

Automated transport, holding, and sorting remove laser-welded pull wire assemblies quickly while reducing handling defects and operator strain.

An interference-fit tube grip and collar create a leak-proof peritoneal dialysis connection while reducing contamination risk and enabling emergency flow cutoff.

An integral flow restrictor and removable poppet balance accurate pressure monitoring with fast flushing to prevent coagulation in disposable transducers.

A blade section axially slits the tube end during insertion, reducing stress, preventing leaks, and simplifying medical tube assembly.

A notched wrapping set screw secures catheter pull wires without manual wraps or welds, improving assembly consistency and inspection.

A freely rotating outer grip lets hose fittings align without twisting the hose, reducing torque, strain, and kinking during accessory changes.

A fluororesin tube with zero or positive longitudinal thermal expansion prevents gaps and air bubbles at catheter connection points.

A reinforced ePTFE tube expands radially for device passage while limiting axial stretch and preventing kinks during access.

Composite radial and axial ePTFE tubing expands for larger device passage while resisting kinking and preserving tube integrity.

Positive axial thermal expansion keeps fluororesin tube connection parts in contact during heat shrinkage, preventing gaps and air bubbles.

Bio-based plasticizers in high-IV PVC tubing cut phthalate leaching while preserving flexibility, strength, and fluid extraction resistance.

A rail-and-cap fastener structure keeps conductive contact during sliding, enabling repeated self-mating attachment between electronic devices.

Capacitive touch gating blocks catheter joystick motion when the operator is not touching it, preventing unintended device actuation.

Radial ePTFE and reinforcement let medical tubing expand for device passage while limiting axial stretch and preventing kinks.

Infrared laser welding joins the shell and collapsible rib to improve analyte sensor assembly reliability while avoiding adhesive-related irritation.

A flexible inner tube with interlaced braid layers balances pressure resistance, bending resistance, and flexibility in medical tubing.

A conductive multilayer irrigation tube dissipates static charge in ablation catheters, reducing RF noise and improving EP mapping accuracy.

A rigid-flange and flexible-cone adapter links cryotreatment hoses to diverse scavenging outlets without country-specific fittings.

A pole- or bed-mounted clamp crimps suction tubing to stop airflow noise while holding the catheter and wrapper clean, organized, and ready.

A reusable elastomer band secures medical tubing without adhesive residue, while auto-loosening under excess force to prevent occlusion.

Localized conduction heating with radial compression dies improves parison stretching control, producing shorter balloon tapers and larger diameters.

Controlled longitudinal thermal expansion keeps catheter connection parts in contact during heat shrinkage, preventing gaps and air bubbles.

Adjustable angled support blocks stabilize outward medical devices to prevent skin compression, vasculature tenting, bleeding, and discomfort.

An accordion collar with guide pins expands over wider ends, then retracts for conformal coupling in automated assembly.

Opposite-wound inner and outer wire layers improve catheter torque transfer to the distal end during both clockwise and counterclockwise rotation.
