Respiratory Masks TRIZ Cases

Pilot pressure constricts the deformable throat, helping a jet venturi generate PEEP while reducing gas flow and device bulk.

A star-shaped nasal bridle uses magnetic retrieval and reduced tissue contact to limit ulceration, infection, and twisting.

A flexible, zoned nasal cushion adapts to facial contours, balancing seal reliability, sight clearance, and patient comfort.

Different prong areas and fittings help lower motor speed, reduce pressure and noise, and clear anatomical dead space.

A ring assembly and optional support mask use negative pressure to capture dental aerosols and splatter at the patient's mouth.

Dual-compartment filtration supports sealed replacement and lower gas pressure drop.

Ambient-pressure storage supplies oxygen on demand while reducing exhalation waste.

Asymmetrical nasal elements and fittings improve dead space clearance while achieving target flow at lower motor speeds.

A breathable medical gas tube absorbs water vapor while a sheath limits expansion, reducing condensate, sensor errors, and flow occlusion.

Asymmetrical nasal elements shape airflow to clear dead space, lower pressure and noise, and support comfortable pediatric use.

This case uses interconnected vessels, an airtight facemask, and relief valves to clear obstructions without positive airway pressure.

Removable conduit sensors share power and data wires for accurate patient-end measurements.

AI analyzes lung sounds and adherence data from a smart holding chamber, reducing reliance on spirometry and parental reports.

A quick-release elbow assembly uses interchangeable exhaust holes and optional noise reduction to simplify CPAP interface use.

Pre-shaped textile tubing supports a stable seal while reducing bulk and leaks.

This case uses telescoping tubular portions with discrete locking to customize breathing-gas tubing length without disassembly.

This CPAP vent assembly uses textile diffusion and membrane-regulated flow to reduce noise and maintain respiratory therapy effectiveness.

Tapered openings and a shroud reduce draft and noise during gas venting.

This case uses semi-rigid headgear, cheek supports, and shaped nasal pillows to balance seal reliability with comfort.

A vibrating mesh aerosol port and compact chamber improve dose efficiency while limiting exhaled-air recirculation.

Isolated air and saline streams cool the body while limiting nasal tissue desiccation.

A modular pad combines elastic support, foam comfort sections, and adhesive bonding for adaptable facial sealing.

Heated air transfers heat through the tracheoesophageal membrane to target esophageal tumors.

This cushion separates adjustment, support, and stabilization areas to fit varied faces while maintaining comfort and reducing air leakage.

A variable-diameter frame socket and deformable connector enable secure tube retention, easier removal, and reduced gas leakage.

A tapered-bead anti-asphyxia valve and diffused venting improve respiratory mask reliability, cleaning, and user comfort.

A multilayer textile headgear uses TPU and reactive adhesive bonding to improve durability, comfort, and environmental impact.

This CPAP comfort pad uses deformable, breathable foam and detachable mounting to distribute facial pressure and support hygiene.

Segmented foam and elastic sections improve facial comfort, sealing, and fit.

An oxygen sensor and proportional airflow control maintain target concentration, while purification and recycling reduce oxygen waste.

This case uses flexible temples, cushioning, and adjustable brackets to simplify secure breathing-mask fitting across head shapes.

A supple concave center seals the nose and upper lip while outer parts resist rotation in low-pressure respiratory use.

A high-flow nasal cannula inside a sealing mask continuously flushes pharyngeal dead space while supporting pressure control.

A sliding element and guide rail pivot the mask forehead support, improving alignment and helping maintain a gas-tight seal.

Woven or knitted diffuser pads replace non-woven CPAP pads to improve bonding, cleaning, noise, airflow, and replaceability.

Shear-thinning bladder seals adapt to facial contours for lower leak rates.

A flexible frame adapts patient interfaces for comfort while maintaining therapeutic pressure.

An integrated ozone generator and diffuser automate PAP sanitization, controlling distribution to protect components and reduce gas use.

This CPAP case uses an annular sealing member that deforms under negative pressure to prevent leakage between detachable units.

A sliding rack and dual-conduit nozzle automate internal hose rinsing and heated-air drying with fresh water.

A flexible respirator liner uses tabs, ribbed texture, and antimicrobial treatment to reduce leaks and skin irritation.

Lateral supports and separate nasal and oral sealing portions reduce leaks while helping maintain therapeutic pressure during sleep.

Respiratory flow analysis triggers probe breaths and EPAP adjustment to maintain airway stability as patient conditions change.

A flexible bifurcated cannula uses smooth, separate lumens and a molded bridge to reduce resistance and condensation during therapy.

An elastic nasal-bridge flap and integrated cushion stabilization improve fit, comfort, and air-leak control without a forehead support.

Grooved wall structures divide exhaled gas into paths that lower pressure and reduce disturbance during respiratory support.

Indirect pressure, flow, and noise measurements help monitor humidifier water quantity without dedicated reservoir sensors.

Voice and airflow signals help a CPAP device detect nasal congestion and adapt humidification or other settings during therapy.

Mechanical stops and timing in a manual resuscitator help deliver prescribed breaths while limiting over- or under-ventilation.

The case uses cycle-synchronized flow adjustment and CO2 rebreathing to damp ventilatory overshoots in Cheyne-Stokes respiration.
