摘要:
A face mask includes a cup-shaped body for enclosing an external respiratory organ, such as the nose, of a patient. Flow of a respirable gas into the body and exhaust of expired gas from the body are unidirectional controlled by respiration check valves. A plurality of detachably securable and interchangeable accessory devices adapt the mask for use with selected prior art scavenging devices.
