Abstract
A tracheotomy valve including a housing defining a chamber therein. The housing having a first opening located in a first plane at one end of the chamber and a second opening located in a vertical plane at another end of the chamber. The vertical plane and said first plane are angled with respect to one another such that a central axis of the first opening and a central axis of the second opening intersect and are angled with respect to one another. The tracheotomy valve also includes a displaceable element disposed in the chamber and movable therein. The displaceable element effects closing of the first opening when in a first position and moves from the first position during inspiration whereby the displaceable element is spaced apart from the first opening and air flows through the housing.
