Abstract

27,450. Thomson, G. M. Dec. 16. Respirators.-An apparatus for developing the lungs by promoting deep breathing consists of a tube a of glass &c. provided with one or more contractions d and a mouthpiece b. The air is inhaled through one or more orifices g, i ; which may be provided with inwardly-directed tubes, as shown at i. The ingress and egress of the air may be controlled by valves, or by the fingers placed upon the orifices. In a modification, the bulb e is made of rubber in order that the flow of air may be checked by pinching it.
