Adjustable Oral Airway Device Sliding Tongue Deflector

The patent applies the dynamics principle by making the oral airway device adjustable through a sliding mechanism. The distal curve region can be positioned at different locations along the longitudinal axis by sliding it within grooves, allowing a single device to adapt to different mouth sizes and anatomical variations. This eliminates the need to carry multiple fixed-size devices.

The patent implements universality by designing a single oral airway device that can serve multiple sizing requirements. The adjustable mechanism allows one device to replace what would traditionally require multiple specialized devices of different sizes, making the device universally applicable to various patients.

The patent applies segmentation by dividing the oral airway device into distinct modular components: a bite block portion and a tongue deflector portion with a distal curve. These segments can be independently positioned and locked, allowing for quick adjustment without complex mechanisms. The grooves and locking features provide discrete positioning options that are easy to select under stress.

The device incorporates self-retaining features through spring-loaded locking mechanisms that automatically secure the sliding portions at selected positions. Once the operator slides the component to the desired location, the locking mechanism engages automatically without requiring additional steps or tools, enabling rapid deployment while maintaining adjustability.
