A non-sterile container (e.g., a spray bottle) that is prefilled with an anaesthetic agent and intended to be used to apply the agent to the oropharynx and upper airway, to relax laryngotracheal reflexes prior to an intervention [typically insertion of an endotracheal (ET) tube or other type of tracheal tube]. It is typically used on non-pharmacologically paralyzed patients where multiple reflexes (e.g., the gag reflex, glottic closure, vocal cord spasm, cough reflex, and bronchoconstriction) could make difficult or inhibit safe intervention. This is a single-use device.
