Respirators TRIZ Cases
- Anesthetic Gas Scavenging Valve Inertia Design
A ventilation valve uses mass and biasing force to control opening pressure.
- Wearer-Controlled Respirator Fit-Testing Apparatus
Automated air-leak measurement unit with wearer-initiated negative pressure testing for respirator fit assessment.
- Deconstricting Airway Devices Using Lateral Mandibular Force
Extraoral cheek pieces apply lateral force to the mandible, maintaining airway patency without triggering gag reflexes in awake or sedated patients.
- Spacer Valve Assembly for Reduced Flow Resistance
An integrated spacer valve reduces flow resistance by merging inspiratory and expiratory functions into one structure, simplifying assembly.
- Vibrational Diaphragm Nebulizer for Aerosol Particle Control
A nebulizer system uses a vibrating diaphragm to generate aerosolized medicament droplets.
- Pressure Therapy System Deep Sleep Enhancement
A pressure generator delivers motor oscillations to enhance deep sleep stages.
- Insufflation System Flow Control for Small Cavities
A processor calculates target gas feeding flow rates and controls valves to adjust suction, ensuring stable operation.
- Portable Oxygen Concentrator Retrofit for Ventilator Integration
Retrofit system merges oxygen concentrator with product tank to deliver enriched gas at pressures and volumes required by wearable ventilators.
- Triple Therapy Inhalation Microparticles for Distal Airway Delivery
Segmented microparticles maintain consistent active ingredient ratios to resolve dose delivery variability in severe COPD treatment.
- Ventilator Blower Heat Pipe Thermal Management
A ventilator blower uses a heat pipe to conduct motor heat away from the compression chamber.
- Breath-Actuated Inhaler with Vibratory Dosing and Flow Sensor
An electronically driven vibratory element releases medication based on detected airflow, reducing dosing errors during user inhalation.
- Frozen Stem Cell Aerosol Delivery for Lung Viability
Aerosolized frozen stem cells undergo phase change to solid state, preventing viability loss from physical stress during deep lung delivery.
- Modular CPAP Apparatus with Detachable Silencer Base
Segmenting the CPAP into a portable main body and a stationary base unit resolves the trade-off between quietness and weight by isolating the bulky silencer.
- Separable Activation Surface for Aerosol Heater
Segmenting the disposable reservoir from the heater prevents residue buildup and toxicant risks while maintaining efficient heat transfer.
- Porous Heatable Substrate for Therapeutic Aerosol Generation
A porous heatable substrate vaporizes a carrier compound to release therapeutic agents into aerosol particles.
- Breath-Actuated Inhalator with PEEP Lung Recruitment
Breath-actuated inhalator triggers medication dispensing after detecting sustained positive pressure, targeting inflamed airways during respiratory distress.
- Medical Tubing Holder with Resilient Clip
Resilient tube holder organizes medical tubing via clip attachment, reducing clutter and improving patient safety.
- Oxygen Concentrator Diagnostic System for Fault Isolation
Diagnostic system analyzes gas properties to isolate components, resolving maintenance challenges from complex device architectures.
- Nasal Tube Bridle with Magnetic Retrieval
A nasal tube bridle uses a magnetic flexible member to secure tubes, eliminating skin irritation from adhesives and dislodgment risks.
- PSA Bed Health Monitoring via Oxygen Sensor
Controller records oxygen concentration series over time against performance curves to assess bed degradation without complex flow control protocols.
- Ultrasonic Drug Aerosol Generator for Respirator Inhalation Sync
Inhaled air sensor triggers ultrasonic atomization only during inhalation, preventing drug waste during exhalation and maintaining oxygen concentration.
- Flexible Membrane Check Valve Low Cracking Pressure
A check valve uses a flexible dome membrane to open fluid flow paths with minimal pressure differential.
