York, N. Y., a corporation or New York Application April =14, 1941, Serial No. 388,448
Claims.
My invention relates to a method of dispensing gases for clinical use and means for safely positioning the containers of different gases in gas administering machines, and has for its object to effect connection of gas tanks, containing individually different gases with the gas conveying passages of a gas administering machine adapted for receiving indicated gases, in such manner that there can be applied to any particular gas passage of the machine only a gas container holding that particulardesignated gas.
In the administration of anesthetics, machines are customarily provided having means for delivering a considerable number of gases, such as helium (He), nitrous oxide (N20), oxygen (02), carbon dioxide (CO2), ethylene (Cal-I4), and cyclopropane (CsHe). It is of great importance that certain gases'are not caused to intermingle under high pressure, as some gases, such for example as ethylene and nitrous oxide, when mixed or intermingled under high pressure will spontaneously explode, and naturally such explosions might prove highly disastrous It is customary yokes leading to a single channel for conveying the gases to the administering passages. of different gases, such as ethylene and nitrous oxide, are set into these yokes, under certain conditions the gases may intermingle under pressure and such an explosion result. It is also im-' portant that connection of any indicated gas shall always be made with the proper administering passages.
It is a principal object of my invention, therefore, in a gas administering machine having interconnecting yokes for holding a plurality of tanks of the same gas, or multiple passages each arranged to deliver a difierent gas, to form, on the connecting means for each gas to go through the gas administering machine, a projecting portion differently positioned in respect to the nipple leading to the gas delivery passage for each said indicated gas, to form a depressed portion similarly shaped and positioned on' the respective gas containers to be engaged by the projecting portion on the connector of the gas administering machine for the indicated gas, and filling said containers with the respective indicated gases whereby connection in the machine can be made only with a container of gas to go through the administering passages of the machine for that indicated gas.
It is a further object of my invention to provide a hanger yoke of an anesthetizing machine using multiple gases with means so related to If tanks,
cooperating means onthe several gas tanks or gas containers that it will be impossible to misplace tanks of specific gases in the machine or I to secure a specific tank in the wrong position.
' in anesthetizing machines to provide double It is a iurther object of my invention to provide the hanger yoke with some kind of a projecting member adapted to enter a depression or opening in the body of the neck of the tank and to position these projections and openings in a respectively distinctive arrangement for each distinctive gas. It follows that only containers having an opening corresponding to the projection from a specific yoke on the machine can be applied to that yoke, and since that container will have stored within it by the gas manufacturer the particular gas designed to be delivered from that particular yoke, 'misplacing of con-.
tainers will be prevented.
Specifically, it is an object of my invention to provide on the several yokes of a multiple gas novel features by which the above enumerated advantageous results are obtained will be particularly pointed out in the claims.
In. the drawings illustrating an application of my invention in one form:
Fig. 1 is a view showing diagrammatically an arrangement in an anesthetiz ing machine of a multiplicity of tanks of different gases as indicated by the symbols thereon.
Fig. 2 is an enlarged full sized view of a hanger yoke for any of said gases with some parts broken away and in section. v

Fig. 15 is a view similar to Fig. 14 after such assembling has been completed.
Fig. 16 is a plan view of a slightly difierent form of assemblage of yoke and bottle neck.
Fig. 17- is a side elevation view of the parts shown in Fig. 16 with some parts in dotted lines.
Figs. 18 and 19 show necks of gas tanks with longitudinal slots positioned relatively in a different place from the slot of Fig. 17.
Fig. 20 discloses another form or another posi- As shown in Fig. 1, a series of tanks IO, N, l2,
l3, I4 and I5 may be supported in a single machine for administering anesthetizing gas in any suitable arrangement and each has connection through its yoke with valve passages (not shown) for delivering each of the specific gases in a certain definite way, as indicated on the machine. These several tanks might contain eacha separate gas, for example, cyclopropane (CsHs) helium (He), oxygen ,(02) nitrous oxide (N20) carbon dioxide (CO2) and ethylene (C2H4). Each of the difierent tanks of gas will be supported in a customary yoke l6 having a nipple base l1 connecting yoke arms I8 and I9 and screw base 20. As customarily formed, tanks III, II, l2, I3, l4 and I5 will be provided with tank neck 2| having a nipple seat 22 at one side for receiving a nipple 23 fast on the inside of the yoke,'surrounded by a compression washer gasket 24. The nipple 23 leads to a passageway 25, Figs. 15 and 17, which support for one indicated gas, in Fig. 2 indicated as N20.
In practice the neck 2| of any gas tank such as I!) to l5, inclusive, is inserted in the open space 28 of'the yoke, Figs. 13 and 16, the nipple seat 22 pressed over the nipple 23 and the neck face forced into gas-tight junction with compression gasket 24 by means of a screw 29 which normally is provided with a conical end 30 adapted to enter a conical seat 3| in the side of neck 2|.
My invention, consisting as it does of providing in the neck of the gas container some sort of opening or channel and providing on the yoke a projection for entering that opening or channel, the above parts being positioned in relation to the nipple seat and nipple so that only one soformed container can be applied to a given yoke, will now be described, as to several different forms.
Referring to Figs. 2, 3 and 4, the yoke I6 providedwith a depending portion 34 has formed thereon a pin 35 projecting outwardly directly below the nipple 23. The tank neck l3 (indicated for oxygen) in addition to the nipple seat 22 is provided with a cylindrical bore 36 positioned identically the same in relation to the nipple seat 22 as the pin-is in relation to the nipple 23. With this arrangement it will be apparent that only a tank of gas having its neck so arranged can be applied to the nipple and yoke of Figs. 2 and 3.
Figs. 5 and 6 show the nipple 23 and nipple seat 22 in their customary position but disclose a pin 31 and a bore 38 which are still below the nipple and nipple seat but diflerently spaced from the pin 35 and bore 36 of the structure of Figs. 3 and 4 which would make impossible assembly of the bottle neck l4, indicated for helium, with the yoke arrangement of Fig. 3.
In Figs. 7 and 8 a pin 39 and bore 40 are angularly disposed to the nipple 23 and nipple seat 22 and hence present another combination wherein assembly of the gas tank ll], indicated for ethylene, could not take place with any yoke other than that having the disposition of the pin of Fig. 7. Likewise the structure of Figs. 9 and 10 have the pin 4| and bore 42 angularly disposed toward the opposite side of the yoke and tank neck from the disposition of these parts in Figs. 7 and8 and hence the bottle neck l2 indicated for nitrous oxide can only be assembled with the yoke having the pin disposed as in Fig. 9 which in the anesthetizing machine would be the position for connection with the gas administering passages conveys the gasfrom the tank to the regulator valve 32 and from there to the proper instrumentalities for delivering the gas to the patient, indicated in dotted lines as leaving the regulator valve at 32'. The gas is released by means of a valve piece 26, Fig. 2, operated by a valve head 21 adapted to receive a handle wrench for that Purpose. As shown in Fig. 2 a second nipple base 33 is provided for connection with a second tank neck 2| having a nipple seat and nipple connection similar to the parts 22 and 23 shown at the right of Fig. 2. This is a customary double yoke of nitrous oxide, and could not be assembled with any other yoke excepting that which would P the gas in communication with the nitrous oxide administering passages.
In Figs. 11 and 12 there are shown the tank necks II and I5 indicated for carbon dioxide and cyclopropane respectively wherein the bores 43 and 44 are angularly disposed with reference to the nipple seat 22, but are more widely spaced than are the nipple seats and bores 22, 40 and 22, 42 respectively and obviously-these tank necks can be assembled only in yokes having pins positioned to enter the bores 43 and 44.
It will be noted in respect to Figs..7 and 8 and Figs. 9 and 10 that since the respective yoke portions and tank neck faces are viewed in opposite directions the apparent arrangement of nipples 23 and pins 39 and 4| on the one hand and of nipple seats 22 and bores 40 and 42 on the other hand appear to have a variant angular-disposition when, though factually, their disposition in each case is identically the same.
In the form of the invention shown in Figs. 13, 14 and 15, a pin 45 is fast on the side arm N of yoke 16. An L-shaped slot formed of a vertical portion 46 and a horizontal portion 41 is formed in the side oi"; a tank neck 48, as clearly shown in Figs. 14 and 15, the horizontal slot 41 being in alinement with the nipple seat 22. In assemblin he tank neck 48 will be moved into the yoke so as to receive the pin .45 in the slot 45 and when the screw 29 is operated to lock the parts in position the pin 45 will travel along the slot 41. Obviously only when the pin 45 ,and the slots 41 are positioned respectively to be in alinement when assembly takes place, can there be such an assembly, so that the relative positioning of pin 45 and slot 46 will determine whether a designated tank can be assembled in a designated yoke.
fagent oi thegas dispenser, insuring their being Tprcperly so positioned. when that has been done In the form of the invention disclosed in Figs.
16 and 1'7, a piece 50 will be mounted to slide on the yoke arms l8 and i9. This piece carries a plate 52 adapted to be seated adjacent the inner wall of yoke member I 9. Upon this plate 52 is an inwardly extending projection 53 which, in assembling, is adapted to enter a slot 54 on tank neck 5i. A screw 55 engaginga bearing 56 on piece so forces the assemblage into gas conducting position. In Figs. 18 and 19 slots 58 and 59 are shown in the necks 5|, which slots are oifset to one and the other side from the position of slot 54.
It is obvious that only when the pin 53 on the plate 52 is so positioned relative to slot 54, 58 or 59 as to be able to enter the indicated one of said slots can the parts be assembled in gas-delivering position. It will be equally obvious that, by arranging a second set of slots similar to 54, 58 and 59 on opposite sides of tank neck 5iand, carrying plate 52 to said opposite side and correspondingly arranging the projections 53 thereon, a series of containers and yokes will be provided .adapted for connection with all six gases indicated in Fig. 1.
As shown in Fig. 20 the same efiect can be produced for. the form of invention of Figs. 13, 14 and 15, -by placing the vertical slot 80 toward one or the other edge of the side of the tank neck in relation to the horizontal slot 41.
.As shown in Figs. 22 and 23, a modification of my invention permits the pin and hole connection of tank to yoke, of Figs. 2, to 12, inclusive, by means which is not-directly connected or integ'ral with the. tank yoke, and which is 'adapt able to be applied to any tank yoke of existing gas administering machines, it being understood that the application of this feature will be made by the manufacturer and dispenser of the diifer- Swaged into a hole in this depending part 65 is a "pin member 61 which has a portion 58 extending outside of the face of plate 62. Thexposed pin part 68 is adapted to enter the variously positioned holes 36, 38, 40, 42 and 44 formed in ,the necks of the gas containers.
In practice the plates 52 with the parts carried thereby will be attached to gas administering machine in use by or under the direction of an it will be impossible to position any container of gas in that yoke and in connection with that indicated gas delivering passage excepting such a container as has the properly positioned hole sembled in a given yoke in the machine, which yoke contains the gas delivering passages for taking to the patient an indicated gas. In this way the assembling of the wrong tank for delivery of a gas other than that indicated in the machine cannot take place. I
A second highly important advantage is tha this arrangement, particularly where the pin on the yoke enters an opening in the tank neck, provides a very eifective tank stabilizer so that the invention serves a double purpose, each part of which is of great advantage in use.
I claim:
