Specification of Letters'Patent.

Patented July 16, 1918.-

Application filed January as, 1918. Serial No. 213,988.

To all whom z't may conoermw g Beit known that1I',.GnoRGE.-W. TODD, a

citizen of; the. United States, residing at, Omaha, in the county of'Douglas and State of Nebraska, havainvented certaln new. and

useful Improvements in Dispensing-Recep-.

tacles for Liquid Anesthetics, of which the following is a specification.

This invention relates to a. dispensing. re-v ceptacle for liquid anesthetics, and. has for one. of its objects to providena receptacle which will conserve the product effective in producing'total ,or. partial insensibility to pain,.for use in the practice of dentistry or surgery. Another object is to provide a,

receptacle for dispensing .a. liquid anesthetic whichmay be conveniently held by the person under treatment" and may be self-admin istered to produce semi-consciousness ortotal insensibility to .pain. The invention also has reference to such a constructionfor the device that the exha-lations of the patient willbe dischargedto the atmosphere instead of' mingling, with. the inhalations, and .includes features found to be. ofadvantage for thoroughly breaking up the liquid, also. for a control of the proportion .of' allIddp mitted to the mixture, and. forconveme'nt:

sanitation. I With the. foregoing, objects. in View and others to be mentioned hereinafter, the .in-.-

vention presents a novelconstruction, combination and arrangement of; parts. as, de-

scribed. herein .andclaimed, and as illustrated 'in the accompanying drawing, wherein, v M

Figure 1 is a partly broken view illustrating one embodiment of-the invention, being asection on line 1-1 of Fig.2. Fig.

2 is a plan viewlofthe' device. Fig. 3v is a transverse section on line 3-3 .of Fig. 1..

Fig. 4 is a transverse section on line of..Fig ..1.. Fig. 5- shows a modified. form for the inhaler; Fig. 6 shows the receptacle providedwithan inhaler constructed integral therewith.

Referring now to,the.drawing,,numeral 7 indicates an elongatedreceptacle.having a comparatively large opening 8'i11 one of its ends, a removable stopper 9- beingemployed to make a closure thereof, the receptacle, at

its opposite end being provided with an exit way or conduit 10 with terminal prongs 11, removable stoppers 12 being employed to make a closure of said conduit.

In Figs. 1, 2 and 3, the conduit is shown to be. removable from the receptacle, the

latter being provided with a bushing 13 in which the. conduit may be threaded. Fig. Gillustratesa conduit 10 which is integral with the receptacle, and I may employ either of theseconstructions since one is the equivalent. of the other. Also, while the receptacle and. the conduits are preferably constructed of glass, any suitable imperforate material may be used.

Numeral 14: indicates an air intake. for the receptacle, thisintake being provided with a hollow cylindrical stopper 15 inv which is removably mounted a comparative'ly small stopper 16, and in operation, the stoppers 12 being removed, air may be admitt'edby removing one of the stoppers 15 or 16, depending upon the volume of air desired for a movement through the receptacle. V 7

Numeral 17 indicates a second elongated receptacle having an open end a, its side walls and end 6 preferably being constructed of wire gauze or equivalent material. It

' is supported in a position adjacent to thebott'om of the receptacle 7, in the recesses a ofthe pairof blocks ,lSwith which the wall of the receptacle 7 is provided, itsopen end being" adjacent to the opening 8. Numeral 19indicates a supplyv of cotton or similar fibrous material with which the receptacle:

l7 is partly filled.

At 20, best shown in Fig. 3', is a chamber in'communication with the intake 14: and the conduit 10, this chamber being disposed above the receptacle 17 and formed bymeans of an arcuate hood or. transversely curved web 21 ofwire gauze, its lower edges being, disposed upon the blocks 18; and the space abovethe foraminous hood 21 and below the receptacle 17 is filled loosely with cot-- ton 22.

It' will be understood that an anesthetic liquidwhen placed in the receptacle 17 will saturate thefibrous element 19 therein, and all of the fibrousparts 22 above the hood and below the receptacle 17 will become saturated to a greater or lesser extent by capillary attraction, this being a desired result so that the gas will become thoroughly modified by the movement of air induced by inhalation.

It will be seen that by use of the present attained or a drowsy condition induced, as

may be required for the particular surgical or dental operation to be performed, the condition of the patient being such that there will be no sensation of pain during said operation.

At d is indicated a frame-member or ring which is secured to the inner side of the receptacle 17 adjacent to the open end there of, this being for use in connection with a conventional glass container having an attenuated neck and used commercially for holding a liquid anesthetic, and being in general use, requires no explanation, except to state that the liquid product is expansive and the container must be broken to make use of the contents. In the present instance, after the stopper 9 has been removed, the neck of the container mentioned is inserted in the ring (Z for convenient breakage, and the liquid contents will be discharged within the receptacle 17 any particles of glass being disposed upon and held by the cotton 19.

Fig. 5 of the drawing illustrates a modified form for a conduit 10 adapted to have a threaded connection with the receptacle and preferably having a flexible part-e of funnel-shape adapted to engage the face of the patient, this construction being of advantage in some instances since it permits a more rapid inhalation.

It will be noted that, by use of the device, the exhalations in all instances will be to the atmosphere, this obviously being of advantage. Also there will be no appreciable loss of the product since, when not in use,

closures of all ports are made by means of the stoppers mentioned.

In addition to the uses of the device mentioned, it should be stated that it is particularly well adapted for the treatment of catarrhal afiections, any of the discharge conduits as shown and described being of advantage for a free delivery of air charged with any one of the various liquid remedies used for that disease, the construction being such that the ail, While moving from the intake 14 to the conduit 10, 10 or 10", will be exposed to the remedial liquids which saturate the fibrous elements 19 and 22.

While I have shown a pair of blocks 18 for a support of the second receptacle 17 and have shown'and described a hood 21 of foraminous material, these features are not.

of importance, but are preferred, since the blocks operate to prevent end thrusts of said receptacle 17 and maintain it in a position adjacent to the bottom of the receptacle 7, and the hood provides an open passageway between the air intake 14 discharge conduit. 7

Having fully described my invention,

receptacle, a fibrous element between the walls of said receptacles, a fibrous element in the second receptacle, said last named receptacle having its open end disposed adjacent to the opening in the end of the first named receptacle to permit a deposit therein of a liquid element, and removable closures for the intake and exit ports andopening in the end of thefirst named receptacle.

and the 2. A dispenser for liquid anesthetics consisting of a' receptacle having afdischarge conduit at one of itsends, its" opposite end having'an opening formed therein, said receptacle being provided with a port for a movement of air't herethrough to said discharge conduit, ad ustable means for limiting the movement of air through said air in take port, a removable closure for theopenmg 111 the end of sald receptacle, a second receptacle having an open end and a foraminous wall, said second receptacle beingdisposed within the first named receptacle with its open end adjacent to the opening in the end of the first named receptacle, a fibrous element between the walls of said receptacles, and a fibrous element in the second receptacle. I

In testimony whereof, I have afiixed my signature in presence of two Witnesses.
