Respirators TRIZ Cases
- Breathing Apparatus Turbine Volute Elastomeric Seal
Elastomeric structure between volute rims resolves clearance leaks and improves gas tightness in breathing assistance turbine assemblies.
- Pneumatic Preflushing Unit for Closed-Circuit Respirator Gas Circuits
A pneumatic preflushing unit automates breathing gas circuit flushing using pressure-driven elastomer valve actuation.
- Dual-Sensor Humidifier Temperature Control
A humidifier uses two temperature sensors to measure water and heating element temperatures independently.
- Capnography System Oxygen Detection via Pressure Differential
A capnography system controller detects supplemental oxygen presence through pressure changes in the sample gas flow.
- Non-Contact Sleep Stage Classification Using RF and Pressure Sensors
A non-contact sleep monitor uses radio-frequency motion sensors and pressure-sensitive mattresses to classify deep, light, and REM stages.
- Nitric Oxide Sensor Stabilization via Reducing Gas
Introducing a reducing gas into the reactor stabilizes sensor signals, resolving cross-interference between NO and NO2 for accurate respiratory monitoring.
- Breathing Cycle Monitoring Using Dual Temperature Sensors
Dual temperature sensors measure air temperature inside and outside a mask wall to calculate a difference parameter that resolves detection time lag.
- Vortex Chamber Liquid Medication Processor for Alveoli Penetration
A vortex chamber processor breaks liquid medication into fine aerosol particles using pressurized air and ultrasonic vibration.
- Aerosol Device Cigarette Detection Heater Control
An aerosol generating apparatus uses a switch to detect cigarette insertion for automatic heater activation.
- Translucent E-Cigarette Conduit Simulating Natural Burn
A translucent conduit diffuses light from an internal source to create a realistic burning ember effect during inhalation.
- Disposable Anesthetic Vaporizer Cartridge with Universal Connection
Disposable anesthetic vaporizer cartridges eliminate operator exposure to liquid agents by replacing complex refill systems with pre-filled, single-use units.
- Optical Interface for Anesthesia Dispensing Device Display
Fiber optic light guides transmit illumination from the main apparatus to the detachable dispensing device display.
