ABSTRACT:
A lock device for holding "open" position of a person's mandible (lower) jaw bone, for facilitating medical treatments such as emergency intubation and other procedures, dental work, etc., particularly on a patient who is either unconscious or for some other reason is not cooperative.
A pair of force lugs, carried on support-beam members, are for imposing a force oppositely against a person's mandible teeth set and upper or skull (maxilla) teeth set. The beam members are pivotally interconnected; and have an extension arm outwardly and rearwardly extending from the outer end, being a retroflex member which in use of the device extends generally horizontally and rearwardly along the person's cheek, providing ease of manual grasping and other advantages.
