Respiratory Device Testing TRIZ Cases
- Flow Generator Messaging for CPAP Service and Therapy Reminders
Time- and event-based messages help CPAP flow generators deliver service alerts, therapy reminders, and patient-use guidance.
- Reflective Visor Position Sensing for PPE Closure Feedback
An optical sensor tracks a transparent reflective visor marker to verify closure in real time and alert workers when PPE is not properly sealed.
- Custom-Fit Respirator Frame With Fit Monitoring for Seal Integrity
Facial-scan customization and embedded fit sensing help a reusable respirator maintain seal integrity during movement while reducing pressure injuries.
- Respirator Seal Verification Using Gas and Valve Sensing
Sensor comparison of gas conditions and valve position verifies respirator seal quality and alerts wearers when a proper seal check is missed.
- Transparent Mask Sealing Structure for Comfortable Speech
A jaw-contact membrane and adjustable retention keep this transparent mask sealed during speech while supporting breathability and filter replacement.
- Piezoelectric Respirator Fit Testing for Low-Noise Aerosol Measurement
Piezoelectric pumps stabilize sheath air and aerosol flow, cutting noise and pressure fluctuations for more accurate respirator fit testing.
- Respirator PM Sensing With Moisture-Protected Fit Monitoring
Dual PM sensors compare inside and outside respirator particles in real time, while a semi-permeable membrane limits moisture errors.
- Respirator Fit Monitoring Using Embedded Pressure And Proximity Sensors
Embedded sensors track respirator fit and particulate-filtering operation in real time, improving safety with alerts for seal or function issues.
- Respirator Valve Prop with Adjustable Locking for Fit Testing
An adjustable locking prop keeps a respirator valve open during fit testing, maintaining airflow and reducing test failures.
- Rotating Respirator Valve Prop for Stable Fit Testing Airflow
A rotating protrusion prop holds the respirator valve open during fit testing, maintaining airflow and reducing negative pressure test failures.
- Sensor-Enabled Respirator Fit Testing With Real-Time Guidance
Expensive, cumbersome fit-testing equipment is replaced by an in-respirator sensor and mobile guidance with real-time remedial recommendations.
- Wireless Breathing Apparatus Monitoring Across Telemetry Gaps
A wireless device combines telemetry and pressure inputs to track non-telemetry breathing apparatus wearers in real time.
- Breathing Apparatus Pressure Monitoring for Non-Telemetry Equipment
A wearable intermediary estimates time-based pressure values, helping incident controllers monitor mixed breathing apparatus fleets.
- Respirator Filter Cartridge Holder With Actuated Fit-Check Sealing
A movable sealing platen switches between filtration and fit-check modes to verify cartridge installation and limit air leaks.
