Respirators TRIZ Cases
- Anesthetic Vaporizer Reservoir Dual-Channel Filling Control
Segmented channels prevent overfilling during tilting or high vapor pressure conditions.
- Respirator Shut-Off Valve for Negative Pressure Fit Check
A respiratory mask shut-off valve isolates inlet ports to create a sealed breathable air zone for fit testing.
- Implanted Bronchial Valve for Lung Isolation
An implanted bronchial valve isolates diseased lung tissue by blocking inspiratory flow while permitting expiratory release at elevated pressures.
- Breathing Gas Dispensing Valve Pressure Compensation
A dispensing valve uses a compensating diaphragm with a deformation zone to manage admission pressure forces.
- Automatic Humidity Control in Pressure Support Systems
A controller adjusts a humidifier based on environmental and respiratory parameters to maintain gas stream humidity.
- Handheld Aerosol Vaporizer with Thermal Conductor
A handheld device vaporizes aerosol agents using a heat generator and thermal conductor.
- Collapsible Spacer for MDI Inhalation Devices
A collapsible spacer mixes pressurized medication with air to prevent rapid inhalation and improve distribution efficiency.
- Portable Oxygen Concentrator Upstream Filter Unit
Segmented upstream filter units with detection mechanisms protect portable oxygen concentrators from hazardous contaminants in prehospital settings.
- Automated Respiratory Therapy Setup via Pathology-Based Parameter Selection
Processor automates pressure delivery settings by associating parameter arrays with respiratory pathology indicators for rapid configuration.
- Bidirectional Firesafe Coupling with Thermal Valve Mechanism
A bidirectional firesafe coupling uses a heat-activated stop to release a biasing valve assembly that seals gas flow upon exposure to fire.
- Individualized Oxygen Therapy for Preterm Infants
A system adjusts oxygen saturation targets using heart rate variability and pulmonary resilience metrics.
- Lithium Hydroxide CO2 Absorbent for Anesthesia Gas
Replacing sodium and potassium hydroxides with lithium hydroxide reduces toxic by-product formation while maintaining high carbon dioxide absorption capacity.
- Respiratory Control Unit Detecting Frustrated Breathing
Programmable control unit analyzes respiratory pressure and flow curves to detect frustrated breathing movements in supportive ventilation devices.
- Bulb Syringe Suction Device with Check Valves for Tracheostomy
Nested catheters and baffle traps enable quiet, manual suctioning that eliminates electric motor noise while retaining secretions.
- Inhaler Prevention Mechanism for Double Dosing
Pressure sensors detect inhaled medicament to release prevention mechanisms, eliminating double dosing risks from separate dispensing and inhalation actions.
- Compact CPAP Tubing with Storage Cradle and Recognition System
Smaller diameter air delivery conduits reduce bulk while recognition systems optimize flow generator performance for full pressure ranges.
