Technical Examples

As disclosed herein, the present invention relates to an improved respirator having a respirator mask, respirator bellows, respirator conduits, and mounting straps attached to the torso of an operator. The respirator mask is positioned over a patient's face so as to cover the nose and mouth. The respirator bellows are positioned under the arms of the operator and are attached to the mounting straps, which may be configured as a vest that can be worn by the operator. The respirator bellows communicate with the respirator mask via the respirator conduits. The operator can deliver air or oxygen to the respirator mask by pumping the respirator bellows with his or her arms. Advantageously, the pumping motion is actuated without the use of hands. The hands-free pumping action allows the operator to firmly secure the respirator mask in proper position on the patient's face with both hands.
