Application filedfi'uly 16, 1914. Serial No. 851,383.

To all whom it m (42 concern Be it known that I, OTTO BUGHHORN, a

subject of the German Emperor, residing at Charlottenburg, near Berlin, Germany, have invented certain new and useful improvements in Apparatus for Creating Artificial Breathing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an apparatus for creating artificial breathing, in which a rhythmical expansion and contraction of the chest is brought about by moving the arms of the person, with which a direct compression of the chest by means of a compressing device can be combined, saidcompressing device being connected to the devices which move the arms of the person by means of suitable connecting members.

'An apparatus suitable for this purpose is shown in Patent No. 1,057,633 of Fries.

The object of my invention is to effect an introduction of oxygen during the inhaling period in addition to the mechanical artificial breathing in certain cases of apparent death.

A source of oxygen, for example, a vessel containing liquid oxygen is connected to the apparatus, a tube being led from said source of oxygen to a breathing device which is to be placed on the person, such as a mask or a tube or mouth-piece to be introduced into the mouth.

At the same time means are provided for connecting the supply of oxygen to the breathing device during the inhaling period, and to disconnect said-supply during the exhaling period. For this purpose a positively controlled valve or any other suitable device can be utilized. I

Two forms of construction of the invention are shown by way of example in the drawings.

tion in side elevation.

The apparatus shown in Figs. 1-4'isprovided with a stretcher "'1 on which is laid person requiring treatment, said stretcher being provided with a downwardly sloping support 2 for the head of the person. The "lowerend of the stretcher l rests on two feet 3. .Near the head end of the stretcher a plate 1 is attached on the lower surface, with which two'tubes 5 are rigidly'connected. 'These tubes are provided near their outer ends with "feet 6,',-which thus serve for supporting the head end of Through the tubes 5 a shaft 7 extends, to the ends of which two levers 8 are attached. these levers a cross-bar 9 is fixed, which, serves simultaneously as a reinforcing'memher and as a handle for the person operating the apparatus.

' Manacles 10 with straps 11for attaching the arms of the person requiring treatment are movably mounted on the levers '8, so

that an-adjustment of sameaceording 'to'the length of the arms is possible. The levers '82116 extended beyond the shaft 7 as shown at S and are provided at these ends "with eyes 12 in which cords 13 are fastened. The stretcher 1 is made narrow at the head end and widens out toward the lowerend. Rods are fixed in holders 14 parallel to the slanting sides of the stretcher, said rods being provided with a number of holes 16.

V'Each rod 15 is providedwith a movable" slide 17 which has an opening 1 8,-"so that the sl de can be fixed 1n any desiredjpo'sition by means of'a pin 65 passing through said opening 18 and one of the holes 16 of justment according to the size of the person.

" As far as now described, the apparatus corresponds in ts action totha't of Patent 105(633. It'is evident that when the system ,of levers 8 is in the position shownfinfFig. '2 (compare the position a shown dotted in To the free'ends of i Fig. 1), the cords 13 exert a tension onithe compressor 21, so that the chest of the person undergoing treatment is contracted. If on the other hand, the system of levers 8 is swung back into the position shown in Fi 1, and still further into the position shown at b, then the cords 13 become slack and the pressure of the compressor on the chest is removed, so that the chest can expand freely to correspond with the movement of the arms.

Below the stretcher there is further provided a vessel 2a supported in holders 23, said vessel containing liquid or compressed oxygen. From the valve 25 of the vessel a tube 26 extends to the pressure reducing valve 27, with which a pressure-gage 28 is 7 connected. From the reducing valve 27 a tube 29 leads to the baglike accumulator 30, which lies between the stretcher 1 and a plate 51 which is guided along rods 52 which are attached vertically to the stretcher. Spiral springs 53 surround the rods 52, said springs hearing at one end against the plate 51 and at the other end against the heads 5 1- of the rods 52 and tending to press the bag 30 together by means of the plate 51. The bag is provided with a safety valve 31 from which a tube 32 leads to a controlling valve 33. The plug 3% of the latter is provided with an axial bore 61 and a slot (32 communicating with said bore. A passage 63 in the valve casing corresponds to said slot, the pipe 32 being connected to the passage 63. The bore 61 of the valve leads into an axial standard 64: of the valve casing to which is connected a tube 49 having a breathing mask or respirator 50 attached to the end. A lever 35 is attached to the lu 3st of the valve 33 and a torsional spring 36 is arranged in connection therewith which has the tendency to keep the Valve always in the closed position (Fig.

A lever 38 is mounted at 39 on a bearing 3?. Into the box-shaped head LO (Fig. 2 of this lever is led a pin 41 which is subjected to the action of a spring 4:2 acting in its longitudinal direction. Further a fixed pivot 4-3 is arranged on the other side of the head 40, with which a rod 4 engages, the other end of said rod being jointedly connected to an arm 45 fixed to the shaft 7. The pivot 39 of the lever 38 is so disposed in relation to the pivot of the arm 35 that, when the lever moves from the position shown dotted in Fig. 3 to the position shown in Fig. 1, the pin 41 first engages the arm 35 and rotates the same around to the position shown in Fig. 4, the pinil gradually approaching the end of the arm during such movement. A slight further movement of lever 38, as will be understood from Fig. :t, releases the arm 35 and permits it to fly back under the action of the spring 36.

The action of the apparatus described above is an follows When it is desired to use the apparatus,

'ing one inhaling period.

the valve 25 of the vessel 2 1 is opened and remains open during the entire period of use. Consequently oxygen flows continuously from the vessel through the reducing valve 27 and the tube 29 into the bag 30, from which it passes into the valve 33 by way of the casing of the safety valve 31 and the tube 32. If the system of levers 8 is in the position a, then the valve 33 is closed, so that the Way to the tube "1'9 is closed to the oxygen. Consequently the whole of the oxygen issuing from the vessel is collected by the bag 30 which is correspondingly in- Hated.

It now the system of levers 8 is moved in the direction of the arrow (Fig. 1), whereby the arms of the person are raised, then the pin 41 of the lever 38 which is moved by the action of the rods 45, 4A engages with the arm 35 and thus rotates the plug 3% in such a manner that the slot 62 enters into communication with the passage 63 in the valve casing, so that oxygen can flow from the pipe 32 into the bore (51 of the plug and thence through the tube 49 to the breathing mask 50. Just before the system of levers 8 has arrived into the stretching position Z) (Fig. 1) then the end edge of the arm 35 has reached the position shown in Fig. 4:, so that on completing the movement of the levers 8 the arm 35 slides away from the pin 41 and the valve-plug 34: returns to the closed position (Fig. 3), in which it is retained by means of a stop a6. 7

The supply of oxygen from the vessel 24 to the bag 30 is regulated in such a manner that the amount of oxygen stored in the bag during the exhaling period together with the oxygen flowing in also during the inhaling period corresponds to the quantity which must be supplied to the patient dur- The bag 30 will thus be emptied by the pressing action of the spring-loaded plate 51 during the inhaling period.

During the exhaling period when the system of levers 8 moves from the position Z) (Fig. 1) back again into the position a, the pin 41 engages with the inclined back of the arm 35 (Figs. 3 and by the action of which it is pushed back into thehead sit) in opposition to the spring 12. As soon as the pin has passed the arm 35, it again snaps forward, so that the entire apparatus again comes into its original position, and a new inhaling can be started.

In the form of construction shown in Figs. 5 and 6, the feet 6 arranged at the head end are formed as holders for the oxygen vessel 24:. From the pressure-reducing valve 27 attached to the oxygen vessel, a short tube 55 leads to one of the limbs of a T-piece 56. To the other two limbs of the T-piece are connected on the one hand the bag 30 and on the other hand the tube 49 leading to the aga rspev shown, then the -belt58 hangs slack, so'that the bag 30 can be infiated and can receivethe oxygen emerging from :the vessel 24. The

7 pressure with which the-oxygen fills the'bag is not suflicient toopen the valve J57 Hnow the system of rods is moved inithedirection of the arrow, which .corresponds to the in haling-period. then .the end of :the belt 58 is woundaround the drum .60. The belt 58 .is thereby .tensioned and presses-rthe bag-30'together. Under this pressure the valve 57 opens, so that the .oxygeniflows to the .res-

.pirator through the-tube-9 :from ithe bag 30 together with the .oxygen flowing .constantly from the bottle 24 through :the

tube .55.

The valve I57 -serves simultaneously as safety valve, :since, if .the movement of :the

arms is stopped, itropens-asrsoon as athe bag 30 has become quite-.filled withoxygen.

In Figs. 5 and .6 a device .isv-also shown, which renders .it possibleyto exert a strong longitudinal pull on thebodyof the patient together with:the%sw1nging:movement of the arms. Forthis purpose a deviceiis arranged at the foot-.endof theistretcher,to -which the feet of the patient may .beistrapped. In order notito makethesap iaratus .too l'ong and unwieldy hereby, the oot strapping device is arranged-movably and preferably slidable.

For this purpose a guiding tube 'is'ar- .ranged underneath ithestretcher 1, in which a rodl71:is slidable. At the end of the rod 71 a rest 72 for the feet is arranged, which latter-can be held bymeansof a strap 73. Accordingto-thesize of the patientathe rod 71 is drawn more or less out of the tube 70 and fixed by means of a screw 74.

The stretching device is primarilyintended for use in cases in' which'the chest compressor must be placed entirely outof action or else adjusted so as to be brought only slightly intoaction, as must be donefor example in cases of drowning, in which the efi'ecting of energetic pressure must be avoided on account of the danger attached thereto owing to'the flooding of the internal organs. This novel feature can therefore preferably be used in apparatus which has no device at all for compressing the chest.

Although apparatus with devices for contracting theichest: corresponding to the mo ve' ,ments of the arm levers are described and illustrated herein, my invention is not restricted to such apparatus. It refers also to apparatus :in -Wl1l0l1 only means for 'm'ovring the 'arms are provided. .Itis to V be-observed, namely, that in certain cases of accident, the use of pressure onthe body 1SI10t desirable. In such cases, apparatus without compression devices :for the chest can be used, or in'the' case of apparatus which are fitted with such a device, the latter can be placed out of action.
