ABSTRACT:
Breathing apparatus comprising a mask shaped to contact a user's face and define a breathing chamber in communication with the nose of the user, a gas supply container carried by the mask 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. The gas supply is controlled by the mouth of the user and inhaling from and exhaling to the chamber is through the nose of the user. The operator is carried by the body for association with the mouth of the user for moving the valve control 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. The apparatus can include a fluid-tight connector between the gas supply container outlet and an inlet to the breathing 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.
