1. An apparatus for pulmonary disease treatment which provides for both intermittent positive pressure breathing and medicant nebulization comprising:
- a first source of pressurized fluid;
a second source of pressurized fluid, said second source having a relatively higher pressure source of fluid than said first pressure fluid source;
an aerosol generator having an inlet and an outlet, said aerosol generator connected at its inlet to the output of said first fluid pressure source;
a nebulizer for nebulizing medicant having a first inlet, a second inlet and an outlet, said first inlet being coupled to the outlet of said aerosol generator;
a pressure regulating cycling valve having an inlet and an outlet connected on its inlet side to the output of said higher second pressure fluid source;
a conduit connected at one end to said second source of pressurized fluid and at the opposite end to said nebulizer second inlet, said conduit providing pressurized fluid to nebulize a medicant disposed in said nebulizer;
apparatus outlet means connected to the outlet of said cyclic valve and the outlet of said nebulizer whereby the apparatus outlet dispenses humidified air combined with a nebulized medicant. IPPB

Abstract
A device for the treatment of pulmonary ailments including an intermittent constant pressure breathing apparatus which simultaneously provides both humidified air and a nebulized medicant through a single breathing tube. The device is characterized as being very compact and portable and is adaptable to several modes of operation, including supplying humidified air alone, providing nebulized medicant along, or simultaneously providing nebulized, humidified air and medicant. Various modes of operation may also include providing intermittent positive pressure breathing to a patient.
