Jan. 5, 1932. J. F. BLANCHARD THERAPEUTIC GAS GENERATRV Filed July 1, 1930 WMI y Swank-o@ Patented Jan. 5, 1932v UNITED. STATES "PATE-N11: OFFICE;

' amsn. BLANCHARD, or nUNrrNafroN rmx, oALnomu I mnnnsrnurro eas enumeran f application ma my v1, mso. sensa maman.

TheV present -invention relates to improvements in therapeutic gas generators, and has for an ob'ect to provide an improved medicinal gasi 'ng device for administering gaseous `medlcaments through the mouth and nose.

Another object of the Vinvention is to provide a compact and simple form of device having a high atomizing action and adapted to quickly gasify the liquid medicine.

A further object of the invention is to provide anim roved gasifying unit which will have the e ect to secure purity of gas and a proper mixture and proportion thereof.

With the foregoing and other objects in View, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, whereii like symbols refer to like or corresponding parts throughout the several views, I

Figure 1 is a vertical sectional view taken through an improved therapeutic gas generator constructed in accordance with the present invention and shown as applied for use. Fi re 2 is a horizontal section taken on the line 2- 2 in Figure 1, and

Figure ,3 is a perspective view of the im-l proved gasiying unit.

Referring more particularly to the draw ings, 5 designates the lower portion of a bronze or other container in which the liquid body of the medicine is contained and indicated at 6. In the upper globular portion 7 of the container which encloses the gas space, is arranged the gasifying unit and supported therein in any appropriate manner. This unit includes the cylindrical wall 8, from the lower edge of which extends the inverted conical bottom 9.

The liquid suction tube extends up through the center of the conical bottom 9 c flange 31 to directthe liquid medicine down into the lower portion 5 of the container. vA 96 and its lower end is immersedin the liquid body 6. The upper end of the suction tube 10 extendsfintb a socket in a nozzle block 11 mounted within the container wall 8 and having therein the conical nozzles -12 and 16, the axes of which are disposed at substantially right angles whereby the jets oi' streams from 29 the nozzles will intercept one anotherat a point just beyond such nozzles.-

The vertical nozzle 12 is an extension of the socket in which the suction pipe 10 is fitted; while the horizontal nozzle 16 com- 55 municates with a space 17 into which the compressed air pige 18 is screw threaded or otherwise remova ly connected. f

This compressed air ipe extends up `lthrough the container wal 8 and connects so with passages 19 in the top cover 20 of the device. The passages 19 connect with a pipe V21 in communication with a source yof come pressed air sup` ly. The cover is provided with a remova le plug 22 through which the 66; medicine 6 may be introduced into the device. This cover 20 is also provided wit a connection for the flexible tube 23 to which the face cover or hood 24 is attached. This hood 24, in Figure 1, iszillustrated as extending over 'l0` the face of the patient. Y

A baille plate 2,5 is disposed within the container 8 and is diagonally disposed extending from the junction of the wall- 8 with the bottom 9 .at a point remote from the nozzle block 75 l 11 and extending up diagonally toward and above the nozzle block and intercepting the stream of compressed air issuing from the` nozzle 16. The side wall 8 is provided with one or more perforations 26 at the base thereof just above the point of connection with the baffle 25. The hopper bottom 9 is also provided or more drain openings 27.

A screen 28 is stretched across the gasiying 85 chamber within the container 8 just above the nozzle block 11 and upper end of the bame plate and a second vertical screen section 29 surrounds the upper ropenportion of the chamber and forms substantially a continua -90- tion of the side wall 8. e This screen section 29 may be carried by a` cover 30,formed with a downturnedmarginal boss upon the cover 30 provides for receivingl the compressed air pipe therethrough. The

container wall 8 is formed with a'shoulder 33 at its upper end to receive the screen section l In the use of the apparatus, com ressed air is turned into the pipe 21, descen through the pipe 18 and enters the nozzle 16, from which it issues in a minute stron stream.

l This stream crosses the mouth of t e nozzle 12 causing a suction of the liquid medicine 6 up through the suction tube 10. This liquid medicine is ent'rained with the jet of compressed air and the mixture impinges against l0 the bale plate 2'5, being broken up and gasiiied thereby, and deflected downwardly toward the hopper or conical bottom 9, .which will catch any precipitated liquid, allowing the excethereof to flow out through the 15 drain openings 27. The gas will riseupwardly through the screen 28 which will strain out foreign matter.

The horizontal screen 28 will have a like eiect and the depending fiange 31 will cause 90 the gas after passing through the screen section 29'to be deflected downwardly, thus providing a baie surface on which any particles of moisture may lodge and drip down into the container below. The puregas goes 25 out through the tube 23 to the hood 24 and is inhaled by the patient.

The device may rest upon a base 34 if desired having an electric or other heating unit 35 therein, which will raise the temperature 3 of the liquid medicine body 6, thereby increasing its tendency to gasify. The fine mesh screens will act to atomize and break up the mixture.

The oily, aqueous or alcoholic solutions I a5 are atomized to such an extent that they can enter the red corpuscles of the lungs and be carried to all parts of the body by the blood. This requires the finest and driest form of gaseous drugs; atomized and nebulized 0 vapors being unable to enter the red corpuscles.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention Without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.I '5 what is claimed is:-

In a therapeutic gas generator, a gasifying unit for inhaling devicescomprising a cylindrical container Wall having an inverted conical bottom, a suction tube entering through the bottom, a nozzle connecting with the tube, a compressed air nozzle angularly disposed to the medicine nozzle, a diagonal baiiie plate extending in front of and above said nozzles, a fine screen stretched across said container above the nozzles and bale plate, a cover having a marginal downwardly directed flange, and a screen stretched between the cover and wall of the container.
