ALEXANDER BERNHARD DRAGER, or LU'BECK, GERMANY. I
MASK, HELMET, OR THE LIKE FOR USE WITH RESPIRATORY APPARATUS.
To all whom it 122 (1 concern:
Be it known that I, ALEXANDER BERN- TIARD DRiiGER, a subject of the German Emperor, and resident of Liibeck, in the German Empire, have invented new and useful Improvements in or Relating to Masks, Helmets, or the like for Use with Respiratory Apparatus, of which the following is a specification.
The present invention relates to an apparatus for producing artificial respiration in which air or another gas'is alternately supplied to and abstracted from the respiratory organs corresponding to the natural inhalation and exhalation. In particular, the invention relates to devices of the kind in which the conduits adapted to be placed alternately in communication with the respiratory organs areplaced in communication one with the other and with a delivery and suction nozzle supplied with a compressed gas for the purpose of producing inhalation and exhalation in such a manner that it is possible by alternately connecting the conduits with the respiratory organs to produce inhalation by the pressure and exhalation by the suction of one and the same nozzle.
The object of the present invention is to provide an apparatus of this kind by which a person using the apparatus to revive another, is afforded the possibility of effecting the manipulations with the utmost speed and certainty.
This problem is solved in accordance with the present invention, by dispensing with all interposed flexible pipes and arranging directly upon the mask itself, that is to be fitted to the person to be revived, a system of passages in which the jet producing or assisting respiration and operating by means of compressed air or oxygen is fitted together with a. reversing member which can be operated to correspond with the ryhthm of the respiration.
By means of this device, not only is the problem referred to above completely solved, that is to say, the facilitation of the manipulations by the person effecting the treatment but in addition the device presents the advantage that this person no longer requires any assistance from others as was hitherto required. The weight of the apparatus as a whole is also largely reduced so that it is possible to enlarge the gas supply reservoir Specification of Letters Patent.

correspondingly and therefore carry a larger quantity of oxygen or compressed air.
Finally, it should be noted that as compared with the apparatus hitherto known, the novel device presents the advantage that the residual air is reduced to the minimum.
In the accompanying drawing-Figure 1 is a vertical central section of a mask embodying my invention, the air controlling member being in position for causing an exhalation. Fig. 2 is a like view showing the air controlling member reversed for an inhalation. Fig. 3 is a transverse section on line 3-3 of Fig. 1. Fig. 4 is a transverse section on line 4-4 of Fig. 2. Fig. 5 is a transverse section on line 55 of Fig. 1, and Fig. 6 is an enlarged perspective view of the air controlling member.
The mask is preferably made in the form shown being adapted to cover the mouth and nose of the patient and consists of side walls a, an exterior front or end wall a, and an interior wall a which is parallel to the wall a.
Between the exterior and interior walls a, a is formed an endless partition I) which is substantially parallel to the side walls a throughout the greatest portion of its length and forms with said side walls a curved air conduit or passage 0.
Compressed air or oxygen is introduced into the passage 0 at the base and at one side of the mask.
The device for supplying the air or oxygen consists of an injector nozzle 0!, projecting upwardly .into the passage at the point above described, said nozzle being connected by a socket e to a flexible supply pipe 7.
The passage 0 communicates with the interior of the mask, 2'. 6., the portion behind the interior wall a and with the atmosphere alternately through a reversing member or cock 9 which is situated at the bottom of the passage 0 and'at the side of the mask opposite the nozzle (Z. The cock 9 consists of a cylindrical plug, (Fig. 6) rotatably mounted in the mask, and formed with a front axial passage h which connects passage 0 with the atmosphere and a rear axial passage 71 which connects passage 0 -with the interior of the mask, said connecting passages 71. and i having ports h and 2" respectively at diametrically opposite sides of the plug.
hen the cock is in the position shown in Figs. 1 and 3, the interior of the mask, be-
hind the wall a communicates with the lower part of the passage 0 behind the nozzle (2 through the passage 2' and port a" of the plug or cock g. The swift current of compressed air from the injector nozzle 03 passing upward entrains the air at the left of the nozzle in the bottom of passage 8 and the entrained air in turn sucks the air, from the interior of the mask through passage i and port a" and is carried in the path indicated by the arrows, around the partition 6 through the port h and out of the mask through passage h which is. in communication with the atmosphere.
When the plug g is rotated 180, into the position shown in Figs. 2 and 4:, the interior of the mask communicates with the passage 0 in front of the nozzle, the compressed air, issuing from the nozzle d, passes up along the conduit or passage 0 around the partition I) and down said passage through the port a into the passage '11 which extends through the interior wall a I claiml. A respiratory mask comprising an inclosing member for the face of a person, an air conduit formed in said member, an injector nozzle projecting into said conduit and arranged to produce a current of gas within the conduit in front of the nozzle and a suction behind the latter, a cock in said conduit having two passages adapted to communicate alternately either with the conduit in front of the nozzle or with the conduit behind the nozzle, one passage being "in communication with the interior of the inclosing member and the other passage in communication with the atmosphere, said valve being operable to correspond with the respiratory rhythm.
2. A respiratory mask comprising a face inclosing member formed of side and end walls, an interior wall cooperating with the end wall to form an air chamber in the front part of said member, a conduit formed in said chamber, an injector nozzle at one end of the conduit, a rotatable cock in said conduit having two passages provided with ports in opposite sides of the cock, one passage leading to the interior of the mask and the other to the atmosphere, said ports arranged to alternately connect the respective passages with opposite ends of the conduit,
and then to reverse such connection.
