A combined microphone and fluid-delivery apparatus integrates a mouthpiece assembly into a headset structure for hands-free operation.
A coupling device for breathing apparatuses integrates flow check valves to enable rapid gas source switching.
Differential pressure sensors detect airflow through an eccentric venturi, enabling a controller to adjust motor speed and maintain precise flow rates.
Periodic fan activation synchronized with respiratory rhythm prevents vacuum conditions and contamination while maintaining breathing volume.
A respiratory mask seal uses a unitary super-elastomeric material to conform to facial structures.
A breathing apparatus with a floating frontwall prevents dislodgement from external forces, ensuring continuous gas delivery.
A 3D printed contoured mask distributes pressure across the face using a rigid outer layer and flexible inner structure, preventing eye dryness.
