Tracheal Tubes TRIZ Cases
- Tracheostomy Cannula Tapered Section for Safe Tube Changes
A tracheostomy cannula features a tapered distal section and proximal suction opening to enable safe inner tube replacement.
- Airway Device Laryngeal Cuff Asymmetry and Sealing Bulge
Asymmetric laryngeal cuff design with annular sealing bulge prevents rotation and over-insertion while adapting to variable upper esophageal anatomy.
- Nasal Bridle Insertion Guide with Switchable Tip
A flexible insertion guide with a switchable tip directs a bridle introducer through the nasal passage.
- Fenestrated Tracheostomy Tube Stiffening Plate
Embedded stiffening plate prevents buckling in fenestrated tracheostomy tube.
- Airway Assist Device Ratchet Mandible Protrusion Oxygen Delivery
Ratcheted airway assist device protrudes and distracts the mandible to maintain oropharynx patency while delivering oxygen and monitoring carbon dioxide levels.
- Breathing Assistance System Speech Detection Tracheostomy
A breathing assistance system detects vocal cord vibrations to redirect exhaled air through the upper airway.
- Brown Algae Polyphenol Coating for Stenosis Prevention
Ecklonia cava polyphenols coat intubation tubes to inhibit collagen accumulation and prevent re-stenosis after airway dilation.
