Intravenous Devices TRIZ Cases

Segmented reception zones in an intraocular administration device accommodate diverse needle dimensions while maintaining precise placement positioning.

An adhesive seal between the lid interior and liner flange prevents spillage and leakage in medical suction systems.

A vascular connector system with a venous outflow limb diverts blood flow to maintain velocity.

A valve mechanism with a rotatable member controls liquid nutrient delivery in automated feeding systems.

A retaining member secures the mechanical assembly within the housing, causing permanent damage upon forceful disassembly to prevent refilling.

A medicament delivery device uses a rotatable indicator member linked to the plunger rod for visual status feedback.

A medicament training system uses multi-sensory feedback to guide users through injection steps.

Impermeable polymeric covering prevents silicone contamination of PVA substances while reducing friction through a self-locking barrier mechanism.

Replacing gear wheels with a friction wheel assembly eliminates jamming risks from foreign substances while ensuring reliable dose delivery.

An electrosurgical electrode assembly conducts current through a suction channel to ablate tissue blockages at the aperture.

Longitudinal hollow protuberances form cavities that enable nested stacking and drainage apertures to prevent humidity accumulation.

An adjustable driver selects springs based on chamber size to maintain consistent force, resolving the trade-off between reliability and adaptability.

A slide clamp releases an internal occlusion clamp while simultaneously pinching the delivery tube to stop fluid flow.

A connector housing features a recessed tip receiving section that limits male connector insertion depth.
