Breathing Masks TRIZ Cases
- Dual-Pressure Ventilation Interface for Separate Nasal and Oral Gas Delivery
A segmented ventilation interface delivers pressurized gas through separate nasal and oral channels to improve patient comfort.
- Face Mask Strap Tightening Mechanism for Gloved Operation
Centralized pulling mechanism tightens all straps simultaneously, eliminating glove removal hazards and reducing time to secure an airtight seal.
- Dual-Cushion Patient Interface for Comfort and Seal Stability
Segmented cushion design resolves comfort versus sealing trade-offs by distributing pressure over a larger area while maintaining a leak-resistant seal.
- Cold Weather Mask with Turbulent Mixing Chamber
Turbulent mixing in a non-rigid chamber balances temperature and humidity, preventing fogging while allowing unobstructed breathing.
- Reusable Respirator-Facemask With Segmented Filter Interface
Segmenting the head interface from replaceable filters resolves manufacturing availability constraints while maintaining high sealing reliability.
- Swivel Elbow Sealing for CPAP Mask Leak Reduction
Segmented swivel elbows with flexible spring arms reduce leak rates and noise, ensuring consistent CO2 washout in CPAP therapy.
- Unidirectional Flexion Clip for Respiratory Mask Strap Positioning
A flexion coupling system adjusts respiratory mask strap placement using a composite rigid-flexible structure.
