Respiratory Device Testing TRIZ Cases
- Mask Seal Leak Detection via Pressure Decay
An automated mask seal test replaces manual inhalation with electronic pressure sensing to detect slow leaks and track compliance records.
- Breathing Gas Visual Indicator Using Light Transmissive Tube
A breathing gas visual indicator uses a light transmissive tube to show remaining air levels.
- Adjustable Facemask with Multi-Zone Seals and Test Scissors
Multi-zone seals and a self-centering strap system accommodate diverse head shapes, while passive test scissors verify seal integrity without chemical agents.
- Respirator Mask Segmented Body Casing Design
Segmenting the mask into a rigid body and soft casing allows fit testing ports without crushing the structure.
- Merged Inhalation Port for Multi-Filter Respiratory Mask
A respiratory mask merges multiple filter airflow paths into a single inhalation port to reduce component count.
- Head Simulator with Air Delivery for Respirator Testing
A head simulator uses an air delivery device to move gas through a simulated trachea and oral cavity.
