Tracheal Tubes TRIZ Cases

A known-length separator fixes the catheter reference distance and avoids complex tracking hardware during insertion.

Patient images measure tracheal diameter and pathway length to recommend ETT diameter and insertion depth for accurate placement.

Selective adsorbing regions capture disease-associated VOCs from breath, simplifying early screening and progression monitoring.

An evaluation device checks O2 changes across multiple breaths to identify humidity-impaired sensors before readings become inaccurate.

Integrated tube electrodes stimulate laryngeal tissue and detect reflex signals for continuous nerve integrity monitoring without vagus nerve dissection.

Manual airway checks can be complex and inaccurate; automated cuff control and respiration monitoring support safer extubation.

A fiber bronchoscope and guide tube use the existing tracheostoma to place a T-shaped tube without an extra incision.

A laminar flow constriction guides gas through a respiration conduit for accurate bidirectional measurement with less dead space and contamination risk.

Combining endotracheal, PEEP, and oxygen connections in one adaptor creates an efficient fluid path for ventilation and oxygen supply.

A flexible barrier shifts between covering and access positions to retain liquid chambers while enabling hygienic replacement without disassembly.

Controlled taste, smell, or mechanical stimulation prompts tongue movement and swallowing to improve airway patency without waking the user.

Open channels keep airflow pathways accessible, limiting mucus occlusion while reducing throat irritation and simplifying cleaning for longer wear.

Electronic links between the humidifier, ventilator, and peripherals coordinate settings and sensor data for accurate breathing-gas delivery.

A nested HME element fits inside the tracheostomy connector to reduce bulk and deadspace while enabling twist-free replacement.

A collapsible transparent sphere isolates a patient during intubation while supporting compact storage and protection from airborne contaminants.

A preloaded flexible membrane opens and seals the tracheostomy valve quickly, reducing airflow resistance and operating noise.

Multiple fluid lines coordinate rinsing, suctioning, cuff inflation, leak detection, and venting to manage airflow and secretions during ventilation.

A pivotable tank cover and integrated gas passages simplify cleaning while maintaining gas-tight delivery of humidified respiratory gas.

A tethered magnet positions the soft palate between tube and tether to deter patient tube removal and unplanned extubation.
