Abstract

324,177. Stevens, C. H. Dec. 6, 1928. Spirometers. - A lung capacity testing device of the kind wherein the expelled air displaces liquid from one bottle to another has an expansive chamber which is distended by the person under test. One bottle has an outlet d connected by a tube h to the other bottle. A Y-tube e passes through the closure e of the first bottle and its limbs b, i terminate respectively in a mouthpiece a and distendable bladder f. The air from the lungs of the person under test first distends the bladder as at g, the mouthpiece is then clipped and the air from the bladder displaces water from the firsb to the second bottle.
