Respiratory Masks TRIZ Cases
- Pulsed Oxygen Delivery System for Closed Breathing Environments
A pulsed oxygen delivery system synchronizes timed gas boluses with user inhalation cycles using electronic breath sensors and control valves.
- PAP System Articulated Outlet Tube Assembly
Segmented rigid and flexible components in the outlet tube assembly accommodate varying forehead shapes while maintaining stable airflow.
- Self-Powered Oxygen Flow Indicator Using Bernoulli and Seebeck Effects
A flow indicator uses oxygen kinetic energy to generate voltage via the Seebeck effect, powering illumination without external batteries.
- CPAP Interface Sealing Structure with Non-Uniform Thickness
A patient interface device uses a single-layer sealing structure with non-uniform thickness to deliver pressurized gas.
- Adjustable Respiratory Mask with Dynamic Seal
A dynamic seal mechanism adapts to varying facial contours, resolving inventory complexity while maintaining positive airway pressure.
- Composite Textile Cushion for Respiratory Masks
Bonding resilient silicone to a textile layer creates a self-supporting profile that reduces pressure sores while maintaining structural integrity.
- Adjustable Nasal Pillow Mask With Rotating Pillows
Rotating nasal pillows and deformable sidepieces reduce pressure on the nare region while maintaining a secure seal for positive air pressure therapy.
- Ventilator Mask Size Detection and Parameter Adjustment
A ventilator system detects attached mask size to automatically set air pressure, breath volume, and respiratory rate.
- Breath-Actuated Oxygen Delivery via Temperature Sensing
A fluid delivery system triggers oxygen flow using a temperature sensor to detect inspiration onset within 10-20 milliseconds.
- Pneumatic Oxygen Delivery System with Flow Control
A pneumatic system redirects oxygen flow using a pressure-sensitive control element to synchronize delivery with patient breathing phases.
- CPAP Snore Detection Using Filtered Expiratory Noise
A CPAP system detects snoring by comparing filtered inspiratory and expiratory noise levels to identify acoustic events.
- Manual Resuscitator Conduit for Single-User Seal
Extending flexible conduit links compressible bag to mask, enabling single-user operation without rescuer fatigue.
- Swivel Elbow Baffle for CPAP Mask Noise Reduction
Planar baffle separates intake and exhaust pathways in a swivel elbow, reducing turbulence noise while enhancing CO2 washout efficiency.
- U-Shaped Silicone Cushion for Face Mask Edge Comfort and Seal
A U-shaped silicone cushion clasp prevents air leakage at lateral mask edges while absorbing elastic tie pressure to eliminate skin irritation.
- Internal Cannula Nebulizer Axisymmetric Flow Rain-Out
Nebulizer positioned within cannula body directs flow along the nasal prong axis, eliminating mixing chambers and reducing rain-out.
- Respiratory Therapy Apparatus High Flow Detection
A respiratory therapy apparatus detects high flow usage by analyzing air circuit signals for specific oscillation patterns.
- Respiratory Mask Scattering Chamber for Skin Protection
A scattering chamber diverts oxygen flow away from patient skin, while an outgas collector assembly ejects exhaled emissions to prevent re-inhalation.
- Respiratory Mask Forehead Coupler for Leak Reduction
A respiratory mask forehead coupler links headgear straps to a frame via a tongue-groove interface.
