    N° 20,473 A.D.1900 Oite of Application, 13th Nov., 1900—Accepted, 26th Jan., 1901 COMPLETE SPECIFICATION. Improvements in Medical Vaporizers or Inhaling Apparatus. I, Robert Lee Benson, Manufacturer, of No. 157, Michigan Avenue, Chicago, Illinois, one of the United States of North America, do hereby declare the nature of this invention and in what manner the same is to he performed to he particu¬ larly described and ascertained in and by the following statement: — 5 This invention relates to atomizing vaporizer apparatus. It is well known that the inhalation of vaporized medicaments is very efficacious in the treatment of nearly all diseases of the respiratory tract; but one difficulty that has presented itself in the thorough application of drugs to affected air-passages has been in the expense, unsatisfactory action, and imperfect construction of atomizing in- 10 halers that have been formerly used. Especially is this rule in any vaporizing apparatus for individual use that has heretofore been devised. It is also well known that mere inhalation of the medicaments is not sufficient to force them into all portions of diseased lungs, from the trachea bronchial tubes down and into the pulmonary, alveoli. While it is possible to carry minute nebulized medica- 15 ments into the smallest bronchi and pulmonary alveoli of a healthy lung, this is not true of a diseased lung, where it is partially, through adhesive inflammation, closed these passages, and, as scarcely any fresh air enters such lung passages, substances mixed with air will not enter. It is therefore necessary to apply pres¬ sure at the entrance of the respiratory passages, and by the joint action of pres- 20 sure and aspiration secure the desired absorption of medicament that the aspiration alone would not effect. It is the object of my invention to provide inexpensive improved means for over¬ coming the mechanical difficulties in the way of the satisfactory operation of nebulizing atomizing apparatus for individual use, by which chemically pure 25 atomized vapor may be thoroughly suppled to the air passages of the respiratory tract under pressure, by the patient himself, or by some one for him, either at home or when travelling about. Generally speaking the entire apparatus of my invention when completely assembled, comprises a pump, a filter through which the pump is adapted to force d() air, a chamber receiving the air, a nebulizer through which the air is then forced, means being preferably added for heating the medicated menstrum before it is passed to the lungs. Parts of this apparatus may be used, however, and still come within the spirit of my invention. I have provided an improved nebulizer having relatively adjustable nebulizing ducts or tubes, one being preferably longi- 35 tudinallv placed with respect to an induction duct or tube and transversely with respect to an eduction nebulizing duct or tube, the longitudinal nebulizing duct being preferably mounted upon a sleeve and longitudinally movable with respect thereto. The pump is also of improved construction, having improved valves that make its operation very efficacious. 40 I will explain my invention in detail by reference to the accompanying drawing in which Fig. 1 shows the assembled apparatus partly in section ready for use, the cover of the containing case being removed; Fig. 2 a detail view of a portion [Price 8<i.]
