Respiratory Masks TRIZ Cases
- Single Prong Nasal Cannula With Stabilization Patches
A single prong nasal cannula with a flexible wire and stabilization patches reduces skin irritation by separating oxygen delivery from mechanical support.
- Patient Interface Conduit with Silicone Pad for Stable Sealing
Silicone conduits with attached pads stabilize patient interfaces, resolving discomfort from obtrusive mask designs.
- 3D Facial Contour Mask Fitting System
Optical scanning generates 3D facial contours to automate mask selection, resolving manual measurement bottlenecks and improving fit accuracy.
- Prong-Free Cannula Gas Flow-Focusing for CO2 Sampling
A prong-free cannula uses a gas flow-focusing device to capture exhaled carbon dioxide without nasal insertion.
- CPAP Mask Cushion Channel with Partial Bead
A CPAP mask channel employs a partial bead to secure the cushion, reducing manufacturing complexity while maintaining attachment reliability.
- Dynamic PEEP Adjustment via Respiratory Reactance
A ventilator system adjusts extrinsic positive end expiratory pressure using real-time respiratory reactance measurements.
- Adhesive Wing Pediatric CPAP Mask for Neonatal Patients
An adhesive wing design eliminates bulky headgear, providing a reliable air seal for pre-term infants while preventing discomfort during side sleeping.
- PAP Mask Selection Using Facial Image Analysis and Machine Learning
Automated image processing replaces manual measurements to reduce clinician time while improving mask fitting accuracy and patient compliance.
- Spring-Loaded Piston Aspiration Device for Airway Clearance
A spring-loaded piston mechanism generates vacuum pressure through a facemask to dislodge airway obstructions.
- Nasal Cannula with Deformable Reservoir for NO Delivery
A nasal cannula assembly uses a deformable reservoir to separate nitric oxide from oxygen until inhalation.
- Elastic Connection Element for Nasal Cannula Sealing
An elastic connection element snugly fits a nasal cannula into a patient interface through hole to create a secure pneumatic seal.
- Nasal High-Flow Therapy Cannula Pressure Monitoring
Derives actual cannula pressure via Reynolds number compensation to prevent ambient air inhalation and maintain respiratory safety.
- Breath-Powered Positive Airway Pressure Device
A breath-powered positive airway pressure device uses a resiliently flexible expiratory chamber to pressurize inspired air without external electricity.
- Breathing Device With Permeable Rebreathing Chamber
Permeable flexible air chamber regulates CO2 levels and rebreathing ratios to treat migraine, epilepsy, and asthma by controlling cerebral blood flow.
- Non-rebreather Mask with Angled Inlet and Variable Stiffness
Variable stiffness cup mask directs oxygen via angled inlet to reduce CO2 retention and improve sealing across face geometries.
- Mouth Cushion Membrane Seal for CPAP Leak Reduction
A flexible membrane surrounds the undercushion to form a continuous seal around the patient's mouth.
- Sleep Management Vending Kiosk with Facial Scanning
A sleep management vending kiosk uses facial scanning to recommend and vend appropriate respiratory patient interface devices.
