An expandable airway for insertion into the throat of a patient having two elongated airway forming members each having a curved one-end portion adapted to fit the contours of the mouth and pharynx of a throat of a patient for effecting insertion and removal of the one-end portion of both into and out of the throat of a user. The two members are connected for pivotal movement in response to a force applied at the other end portions from a contracted state to at least one expanded state, wherein the one end portions are spaced apart relative to the contracted state. A holding member is disposed on the other end portion of one of said members for releasably holding the other of said members such that the members are maintained in said at least one expanded state and wherein said holding member is responsive to a force applied substantially in the direction of removal of the device from the throat to release the other of said members for free movement back to the contracted state. |
