VAPOR OR GAS GENERATING APPARATUS.

LQSELSAS.

To all whom it may concern:

Be it known that 1, WILLIAM F. DUNLoP, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Vapor or Gas Generating Apparatus, of which the following is a specification.

This invention relates to an apparatus for generating medicinal gases or vapors for use in the treatment of pyorrhea, ulcerations and other like pus-produced and pusproducing diseases of the gums, teeth and other portions of the body, the object of the invention being to provide an apparatus whereby a medicinal gas or vapor of a certain character may be produced and applied directly to the diseased surface so as to remove all pus, poisonous or irritating accumulations and render the diseased parts aseptic, so as to effect a cure without danger of injury to the surrounding tissues.

The invention consists of the features of construction combination and arrangement of parts herein described and claimed, reference being had to the accompanying drawin which 2- Figure 1 is a side elevation of a gas or vapor generating apparatus constructed in accordance with my invention. Fig. 2 1s a larged scale, through the vapor storage tank or chamber and the lower end of the medlcament feed-pipe. Fig. 5 is a detail hori zontal transverse section on the line 44 of Fig. 2.

1n carrying my invention into practice, I provide a tank 1 for containing oxygen, air or other suitable gas under a determined pressure, an oxygen compound of a character devised by me being preferably used. This tank is closed at its top by a head 2, having threaded

openings

3 and ,4. Into the opening 8 is fitted a nipple 5 communicating with the lower end of a valve casing 6 having at one side an inlet pipe or passage 7. This pipe or passage 7 terminates in a clamping yoke 8 whereby it may be connectedto a primary tank containing the oxygen or oxygen compound gas, for replenishing the tank 1 therefrom whenever Specification of Letters Patent.

trolling handle 11. The upper end of the casing is threaded to receive a gland or ad justing nut 12, arranged to bear upon a suitable packing or gasket 13, whereby a gas tight connection is secured, the construction also being such that as the valve wears from continued use the nut may be tightened against the packing to force the valve down into its seat, thus maintaining a gas tight connection.

Arranged within the tank 1 is a vapor storage and mixing tank 14 having a concaved bottom or mixing surface 15. This tank is threaded at itsupper end in the opening 4 of the head 2 and is supported by said head in a pendent position within the tank 1. Suitably secured to the top of the tank 14; is a nipple 16 provided with a passage 17 in communication with said tank, which nipple has detachably coupled thereto a conductor 18 arranged in transverse alinement with the valve casing 6. Through this conductor extends a medicament feed passage 19 communicating at its upper end with a cup or receptacle 20 normally closed by a screw cap or suitable closure member 21. The lower end of the passage 19 communicates with a delivery pipe or tube 22 which extends downwardly into the tank 14 and has its lower end arranged to bear against the center of the concaved bottom 15, the said lower end of the pipe 22 being provided with an annular series of jet apertures 23, for a purpose hereinafter described.

The valve casing 6 is provided at one side with a feed port 2 1 communicating with the pipe 7 and at its diametrically opposite side with a feed port 25. The port 25 communicates with a pressure regulating or reducing valve 26, connecting said port 25 with a gas feed passage 27 formed in the conductor 18. A gas delivery pipe 28 communicates at its upper end with the passage 27 and leads at its lower end into the pipe 22 a distance above the apertured lower end of the latter. The valve 10 has three positions, in one of which it opens communication between the pipe 7 and tank 1 for replenishing said tank with gas, in the second of which it opens communication between the tank 1 and passage 27 for the flow of gasfrom said tank 1 to the delivery pipe 28, in which position it cuts off communication between the tank 1 and pipe 7, and a third or blank position in which the PatentedJune 9, 1914:.

ports

24 and 25 are closed and the valve therefore entirely cuts ofii communication between the tank 1 and the pipe 7 and also between said tank and the passage, 27. In the conductor 18 is formed a third passage 29, constituting a final vapor or gas discharge passage, with which connects one end of a hose or discharge pipe 30. Through this hose or discharge pipe the generated vapor or gas is supplied to the part to be treated. To this end the free end of the hose is provided with ahand piece 31 terminating in a discharge nozzle 32. and into which may be detachably fitted a discharge needle 33 of a restricted diameter,or of a diameter less than the discharge aperture or passage in the said discharge nozzle.

A gage 34 communicates with the tank 1, so. that the pressure of the primary gas or gas compound contained thereinv may be determined at any time, while a second gage 35 communicates either with the casing of the reducing valve 26 or at some suitable point of the apparatus. in communication with the interior of the tank 14, whereby the pres sure of the generated vapor or gas therein may be determined.

In practice, the tank 1 is supplied with oxygen or a. compound oxygen gas toa desired pressure, which gas is stored therein for use as required, and when it is desired to employ the apparatus. for the production of the medicinal gas or vapor a charge of they medicament to be combined with the oxygen gas or oxygen gas compound is introduced into the cup or receptacle 20, whence it feeds by gravity downward through the passage 19 and pipe 22. Upon thev introduction of the medicament the valve 10 is turned to. open communication between the tank 1 and passage 27, to admit the oxygen or oxygen compound gas under a determined pressure into the pipe 28'. The gas. flowing downward through saidpipe enters the pipe 22 at a. point above the jet'orifices 23. and commingles with the liquid medicament, which is of a semi-volatile nature, and discharges the medicament under. pressure: through the jet orifices 23 and against the concaved bottom or mixing surface15 of the tank 14:, whereby the medicament. is thoroughly volatilized and commingled. with the oxygen or oxygen gas compound, forming a medicated vapor of a. certain character which is stored within the chamber 1a. This vapor discharges through the tube 30 and nozzle 31,. by which it may be directed against or into the aifected part torbe. treated. Under a. determined pressure of. the. oxygen or oxygen. gas, compound, which may be regulated by means of the valve 26, and in. the use of the discharge tube without theneedle- 33, the medicament may be injected in the vaporized condition in which it exists in the storage tank 14, allowing it to be used in such condition against the affected surface. The medicated vapor is, however, of such a nature that by applying a needle 33 having a passage which is of constricted size relative to the passage in the nozzle 32, a resistance to the outflow of the vapor will be created, establishing a certain additional pressure, under which the vapor is converted into a clear dry gas which under some conditions of treatment is directed against or into the part to be treated. The needle not only enables this change in the conversion of the medicated vapor into a medicated gas without varying the pressure through the reducing valve, but also enables the gas to be injected into cavities or pockets so as to directly reach the seat of the disease.

The apparatus is especially designed for the production of a medicated gas or vapor for use in the treatment of pyorrhea and other purulent diseases, the gas or vapor being preferably produced from an oxygen compound formed of pure oxygen combined with tissue stimulating agents, preferably alcohol, and oil of peppermint, and a medicament consisting of an aqueous solution of boracic acid, alcohol and oil of peppermint, the vapor or gas thus being saturated with a local antiseptic and certain elements which are precipitated and act upon the tissues to stimulate the nerves and to induce an increased flow of blood to the part, thus providing for the absorption by the blood of an increased amount of oxygen without danger of oxidation of the tissues, and at the same time stimulating the diseased parts so as to assist nature to' a great degree in effecting a cure. The alcohol and menthol contained in the oil of peppermint penetrate the tissues to an appreciable extent, thus allowing the oxygen to come into contact with the diseased cells and to act as a germicide in destroying all diseased matter and germ life and neutralizing the pus, placing the tissues 1n an aseptic condition for a healing action.

It will be observed that the apparatus, which is preferably of a portable character, provides for an efficient combination of the substances named and under a proper pressure to effect the volatilization of the ethylborate solution, and that the discharge of the remedial agent either in vaporous or gaseous form may be readily and conveniently controlled by the operator.
