ABSTRACT:
An apparatus intended to maintain or improve a supine patient's airway in a hands-free environment. A frame and detachable pillow device are placed under the patient's head. Mechanisms extend laterally from the frame and provide jaw support members that may be brought under the angles of the jaw. The jaw support members may slide towards and away from the frame, but this sliding movement is regulated by a unidirectional clutch, such as a ratchet and pawl system, which restricts the jaw support members to sliding movement away from the frame only. When the jaw support members are slid away from the frame, they engage the angles of the jaw, and then thrust the jaw forward to maintain or improve the patient's airway. Once the desired anteriorly thrust position of the jaw is achieved, the unidirectional clutch holds the jaw in place until the clutch is released. The weight of the jaw then causes the jaw support members to slide back towards the frame, restoring the jaw to its normal position.
