Intravenous Devices TRIZ Cases

Segmented barrels merge irrigation with aspiration to prevent apical perforation and remove necrotic debris.

An integral closure unit with a frangible link severs upon removal to indicate tampering.

A wound healing system applies combined positive and negative pressure through porous foam to promote granulation tissue growth.

Segmented screw threads with varying leads allow a tilting nut member to detect the final dose position and prevent under-dosing.

A medical suction handle integrates an on/off valve and thumb-control port within a single housing to manage airflow.

Relocating sensors from disposable blades to the handpiece eliminates blade complexity while maintaining optimal fluid flow through precise window control.

Convex stopper heads reduce capillary adhesion during storage, preventing sticking while minimizing dead space and pharmaceutical residue.

Raised sections with bevels align pharmaceutical containers, preventing twisting and bouncing during transport.

Retaining collars secure a pliable suction tube around teeth, maintaining consistent proximity to aerosol sources while preventing procedure disruption.

Dynamic coupling prevents accidental dispensing during dose correction by locking reverse rotation while allowing precise unidirectional delivery.

A suction apparatus evacuates surgical smoke using an extendable tube and interchangeable tip extensions positioned adjacent to the electrocautery electrode.

Automated meat quality detection system using artificial vision to locate puncture points for precise pH signal measurement.
