Respirators TRIZ Cases
- Resealable Aerosol-Generating Article With Moveable Portion
A resealable aerosol-generating article uses a moveable portion to control fluid communication between medicament sources and airflow pathways.
- Electronic Vaporizer Interlock Logic Circuit
Logic circuit prevents simultaneous vaporizer activation to eliminate doubled anesthesia effects.
- Medical Ventilator Control Film Optical Bonding Hygiene
Optically clear adhesive bonds transparent control film to ventilator display, eliminating sealing joints that trap moisture and increase production costs.
- Dual Control Interface for Medical Ventilator Isolation
A dual control system links an external input device to a ventilator controller via communication paths.
- Inhalation Monitoring Apparatus for Dosing Accuracy
Interactive apparatus detects inspiratory parameters using pressure, flow, and sound sensors to monitor inhalation techniques.
- Dry Powder Inhaler Resilient Transfer Mechanism
A dry powder inhaler uses a resilient member to move medicament from the reservoir to delivery channels.
- Disposable Intubation Device with Bendable Stylet and LED Illumination
A disposable intubation device uses a bendable stylet and integrated LED light for direct airway visualization.
- Capnography-Based Ventilator Weaning Monitoring
A capnograph analyzes expired CO2 waveforms to characterize respiratory patterns during ventilator weaning.
- Piezoelectric Valve for MRI Environments
A linear digital proportional piezoelectric valve uses a motor-driven shaft and follower to control fluid flow.
- Cough Assistance Device Using Periodic Electromagnetic Valve Control
Periodic electromagnetic valve action maintains high cough pressure while preventing airway collapse caused by rapid pressure release.
- Respiratory Tube Identification via Memory Element Reader
A reader unit detects identification data stored in a memory element attached to a respiratory tube.
- Skin Conductance Monitoring for Sedated Patient Pain and Awakening
Skin conductance analysis differentiates pain from awakening by isolating emotional sweating signals, avoiding interference from blood circulatory changes.
- E-Vaping Device Proprietary Threading for Component Safety
Non-standard thread pitch prevents cross-contamination by blocking incompatible component mating.
- Wireless Endoscope with Flexible Guide for Nasal Procedures
A wireless endoscope integrates illumination and imaging into a flexible cylindrical shaft.
- Expandable Absorbent Plug for Nasal Anesthetic Delivery
An expandable absorbent plug delivers anesthetic agents to nasal cavity walls through controlled volume expansion.
- Bi-level Positive Pressure Support for Asthma and COPD
Dynamic pressure adjustment based on airway resistance improves breathing assistance while minimizing medication side effects.
- Lung Replica with Compressible Lobes for Aerosol Deposition
A lung replica uses compressible lobes to generate inhaled and exhaled airflow for spatial deposition studies.
- Portable Nasal Irrigation Device with Integrated Compressor and Hermetic Sealing
Hermetic sealing protects internal components while enabling easy cleaning, resolving infection risks from non-portable traditional devices.
- Triple Drug Aerosol Inhaler for COPD Exacerbation Reduction
Single inhaler aerosol formulation merges three drugs to reduce COPD exacerbation rates by 20-30% while eliminating multiple device management.
- 3D-Printed Orthodontic Aligners with Smart Sensors for Sleep Apnea
Replacing thermoforming, 3D-printed aligners use divot anchors and embedded sensors to simultaneously treat sleep apnea and straighten teeth.
