Tracheal Tubes TRIZ Cases

This case uses 3-axis nosepiece adjustment, rotating eyepieces, and gel pads to fit facial contours and reduce leaks.

A capnography system identifies tubing characteristics and adapts sensing modes to filter artifacts and speed intubation verification.

An elevated member diverts secretions into a disposal housing, preserving air flow sensor accuracy and reducing maintenance.

This case builds patient-specific lung models from similar patients and bedside imaging to reduce VILI risk without repeated CT scans.

A curved coupling member lets an airway device rotate with patient motion and release under excessive force during robotic procedures.

An electro-mechanical trigger and multi-lumen circuit deliver concentrator oxygen directly to the interface, bypassing leaks.

A staged everting vine robot reaches the laryngopharynx and trachea while providing an airflow lumen for emergency intubation.

A dental channel anchors the oropharyngeal airway, while a soft guard protects teeth and gums from clenching damage.

A bridge and deformable fins secure the tube without adhesives, easing insertion and supporting long-term airway management.

Pressurized gas entrains ambient air near the nostrils and synchronizes support with breathing for comfortable, mobile ventilation.

A separable concave tube cradle enables rapid repositioning while preserving endotracheal tube shape and fluid flow.

This case combines a skin-adhesive base with spring-loaded clamping arms to resist tube movement during patient care.

An expanding brush scrubs ET tube biofilms in situ, while a distal stopper contains cleaning liquids and supports continued tube use.

This U-shaped appliance delivers air through an oral passageway, reducing reliance on mandibular advancement and supporting comfort.

A dual-lumen ventilation device uses pressure sensing to confirm placement and synchronize air delivery with chest compressions.

A disposable angle-adjustable blocker combines a soft tip and camera to confirm bronchial position while avoiding bronchoscope disinfection.

Breathing-synchronized PSA pulsing cuts oxygen waste, energy use, and concentrator weight.

Procedure-step detection filters vital signs on a head-worn display, helping clinicians keep patient information visible during care.

A pressure-adaptive cuff conduit expands for reliable flow in tight tracheal spaces.

Pressure feedback adjusts the mouthpiece passage and nasal flow to maintain PEEP and gas exchange during mouth opening.

A compact respiratory therapy platform combines MIE, CHFO, CPEP, nebulization, temperature monitoring, and filter tracking.

A dressing and tube circuit detects electrical discontinuity, warning caregivers before decannulation can cause airway risk.

An anchored stylet stays inside the feeding tube during surfactant delivery, preventing protrusion and avoiding removal before use.

One-way valves and adjustable resistance separate breathing pressure measurements.

An expandable catheter vents hyperinflated lung segments, blocks reinflation, and supports functional lung expansion without surgery.

Continuous electrode capacitance measurements compare SEM values with thresholds to enable early alerts and pressure adjustment.

Manual compression generates suction for continuous throat aspiration, reducing component count and avoiding external vacuum equipment.

Adaptive pressure waveforms lengthen breaths toward six per minute while easing triggering and cycling during therapy.
