Over-moulded Plastic Textile Coupling for Patient Interface

The patient interface combines soft seal-forming materials (such as silicone or rubber) with rigid structural components (such as plastic or metal frames). The soft materials contact the patient's face to provide comfort and conformability, while the rigid components provide structural stability, shape retention, and durability. This composite construction allows each material to perform its optimal function without compromising the other.

The patient interface incorporates adjustable components such as movable headgear straps, adjustable cushion positions, and flexible connection points that allow the interface to adapt to different patient faces and preferences. These dynamic elements enable customization while maintaining ease of operation through simple adjustment mechanisms that do not require complex procedures or frequent maintenance.

The vent components are designed using flexible materials and streamlined structures that minimize turbulence and noise generation during breath passage. The vent openings are positioned and shaped to reduce air flow noise, and the surrounding flexible materials help dampen sound transmission. This allows the vents to provide necessary functionality (exhalation relief, pressure regulation) while minimizing the harmful noise effect.

The patient interface applies different material properties and structural characteristics to different regions: the seal-forming portions use soft, compliant materials for comfort and conformability; the headgear and structural framework use rigid, stable materials for security and stability; the connection areas use flexible elements for adaptability. This localized differentiation allows the interface to achieve secure sealing and stability without compromising patient comfort in the contact regions.
