Respiratory Masks TRIZ Cases
- Swivel Cannula Connector With Sensor Port for Untangled Oxygen Delivery
A rotating quick-connect places the sensor port near the nostrils to prevent tubing twists, improve airflow sensing, and allow fast release.
- Airway Pressure Therapy With Stretch Receptor Activation
Adjustable airway pressure stabilizes breathing, then briefly boosts lung inflation to activate pulmonary stretch receptors and lower blood pressure.
- Integrated Mask Valve Assembly for One-Way Airflow Control
An integrated one-way valve in the mask body prevents airway backflow, stabilizes vacuum, and improves safety in respiratory devices.
- Respiratory Headgear Straps With Variable Elasticity for Easier Donning
Variable-stretch straps and preformed headgear reduce tangling, improve fit, and make respiratory interfaces easier to don.
- Respiratory Suction Mask With Piston Vacuum for Airway Obstructions
A piston vacuum and face-sealing mask clear airway obstructions without a throat tube, reducing injury risk and manual effort.
- Respiratory Mask Harness Coupling for Secure Fit and Easy Handling
Strategic strap receptacles and locking couplings make respiratory masks easier to apply while maintaining stable fit and reducing unintentional release.
- Inhalation Mask Sealing Lip With Pressure-Indicating Stowing Area
A marked stowing area on the sealing lip shows correct mask pressure, improving face sealing and comfort during inhalation therapy.
- Multi-Strap PAP Mask Cap for Hair Protection and Seal Stability
A dual-layer PAP cap uses low-friction lining, high-friction outer fabric, and adjustable straps to reduce hair damage while keeping the mask sealed.
- Respiratory Mask Diffuser Structure for Quiet Vent Flow
Offset bonded regions in diffuser material reduce vent noise and air drafts while preventing fiber blockage and preserving CO2 exhaust.
- Nested Gas Mask Shell for Escaped Gas Capture and Low Noise
A nested shell-and-mask structure captures escaping gas while smoothing flow, lowering noise, and reducing turbulence during patient gas delivery.
- Breathing Mask Coupling Layout for Stable, Easy Headgear Fit
Modular coupling elements reposition mask straps for easier application, stable sealing, and better comfort without a forehead support.
- Modular Breathing Gas Separator for Size-Adaptable Ventilation
A modular separator splits ventilator and patient gases while enabling disposable, size-adaptable parts that simplify manufacture and use.
- CPAP Mask Exhaust Diffuser With Non-Linear Flow Path
A coaxial CPAP exhaust diffuser uses internal ribs and absorbent media to cut noise, disperse air jets, and resist waterlogging.
- Nasal Cannula Shield Assembly for Oxygen Leakage Reduction
Curved nasal shields aligned with cannula outlet ports cover the nostrils to reduce oxygen leakage and improve delivery consistency.
- Over-Moulded Medical Tube Ports for Reusable Condensation Control
Pre-formed over-moulded tube ports localize heating and sensing to cut condensation while enabling reusable medical breathing conduits.
- PAP Mask Sound Monitoring for Dislodgment and Leak Alerts
FFT-based sound analysis detects PAP mask dislodgment and triggers a wearable vibration alert to restore the seal without disturbing others.
- Facial Fixation Structure for Multi-Tube Patient Interfaces
Flexible facial fixation secures respiratory and feeding tubes in limited infant facial space while allowing adjustment without interrupting therapy.
- Ultrasonic Welded CPAP Headgear Joints for Comfort and Fit
Ultrasonic welding creates flush CPAP headgear joints that improve comfort and fit while reducing skin irritation and assembly cost.
- Choking Rescue Mask Sealing and Air Valve Structure
A screw-sealed mask, movable air valves, and top exhaust holes speed choking rescue while preserving airtight suction and easier operation.
- Interchangeable Respiratory Interface Housing for Secure Mask Alignment
Modular cannula and mask bodies use guided manifold alignment and seating feedback to improve fit, seal integrity, and patient comfort.
- Breathing Control Assembly for Eustachian Tube Pressure Protection
Airflow is paused when the eustachian tube opens and resumed when it closes, reducing ear injury risk during ventilation therapy.
- Auto-Adjusting Mask Headgear for Leak Control and Comfort
A directional locking headgear balances elastic stretch and retraction to reduce mask leaks, blow-off, and face pressure.
- Patient Interface Plenum Design for Deadspace and CO2 Washout
A segmented plenum with volume-reducing members cuts deadspace, improves CO2 washout, and helps maintain a stable CPAP seal.
- Rolling Nasal Bridge Seal for Full Face Mask Pressure Relief
A rolling upper seal with reduced stiffness maintains constant nasal bridge force, improving full face mask sealing comfort and reducing sores.
