  • Patent number: 6802316
    Abstract: A tracheostomy valve (10) having a low profile for use on a tracheal tube (100) of a user. The tracheostomy valve is a unidirectional valve which allows gases to enter into the tracheal tube but does not allow gases to exit the tracheal tube through the tracheostomy valve. The valve includes a valve body (12), a flapper valve (24), a valve clamp (26) and a cover (32). The valve body has notches (30) which provide inlets (18) for the gases to move past the valve body. The valve clamp has grooves which provide inlets for the gases to move past the valve clamp into the valve body. The cover mounts over the second end (12B) of the valve body and holds the valve clamp and flapper valve in position in the hole of the valve body.
