ABSTRACT:
A one-way breathing device for use with cardiopulmonary resuscitation training mannequins has a hollow tapered conduit for insertion into the mouth of the training mannequin. A soft rubber outwardly extending flange at one end of the conduit is provided for engagement over the lips of the mannequin. A one-way valve at an opposite end of the conduit allows air to be blown into the mouth of the mannequin, but prevents air from exiting the interior of the mannequin through the mouth. In a second embodiment, a second radially extending flange is provided for engagement with the interior of the mouth of the mannequin to retain the conduit in position. Two different types of one-way valves are disclosed. A first type of valve utilizes a circular valve which is spring biased by a coil spring to a closed position. A second type of valve utilizes a spring biased ball check valve. The one-way breathing device prevents contact of the mouth of a person practicing CPR on the mannequin with potentially contaminated surfaces of the mannequin and also prevents potentially contaminated air from the interior of the mannequin from contacting the face of the student. The one-way breathing device is inexpensively constructed and may be disposed after use.
