Abstract Breathing apparatus comprising a mask for defining a breathing chamber in communication with the nose of the user, a gas supply container having a movable valve control element, and an operator manipulated by the mouth of the user for moving the control to open the valve to introduce gas to the breathing chamber. As a result, control of the gas supply is provided by the mouth of the user and inhaling from and exhaling to the chamber is through the nose of the user. The mask is shaped to contact the user's face around the nose and to define the breath- ing chamber in communication therewith, and the container of breathing gas is carried by the mask with the outlet valve com- municating with the chamber and operable by the movable control element. The operator is carried by the body for operative association with the mouth of the user for moving the valve con- trol element between open and closed positions in response to manipulation by the mouth of the user, and an exhalation valve is in the mask in communication with the breathing chamber. As a result, the supply of breathing gas from the container to the breathing chamber is controlled by the user manipulating the operator with his mouth and inhalation from and exhalation to the breathing chamber is performed by the user through his nose. If desired, there can be included a fluid-tight connector be- tween the gas supply container outlet and an inlet to the breath- ing chamber, a manually operated member for opening and closing the valve, and a pressure gauge in the container for monitoring the pressure of the contents thereof.
