APPARATUS FOR ADMINISTERING ANESTHETIGS. APPLICATION FILED MATEO, 1912. 1,094,301. Patented Apr- 21, 1914.

UNITED sTATEs PATENT OFFICE.

ANsEL MARION cAINE, oF NEW ORLEANS, LOUISIANA, AssrcNon To Monnmuo'r'r SURGICAL INSVTRU'MENT co., LTD., or NEW oELEgANs, LOUISIANA.

Specification 4of Letters Patent.

Patented Apr. 21, 1914.

Application led Hay 20, 1912. vSerial No. 698,558.

To all whom it may concern:

-Be it known that I, ANsEL M. CAINE, a citizen of the United States, residing at New Orleans, inthe parish of 'Orleans and State of Louisiana, have invented certain new and usefulk Improvements in Apparatus for Administering Anesthetics; and I do hereby declare the followin to be a full, clear, and exact description o the` invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to apparatus for use in connection with the administering of ether to patients in surgery, and proposes to provide a means which will in a great measure advance the science of anesthesia.

' The apparatus disclosed herein has for its purpose to enable the administering of continuous and uniform anesthesia with less salivary and bronchial secretion, and less irritation to the bronchi than is now possible; allowing ready regulation of the anesthetic vapor whether the surgeon is operating on the nose, throat, or elsewhere; permitting of freedom of the hands of the anesthetist to assist the operator or surgeon' to the same consists of an ether bottle 1 having an ordinary mouth 2 of ound glass, that is'iitted with a rubber corr provided with two` erforations .or apertures extending therethrough. Through one of the apertures 4 is leda lon copper tube 5, which' extendsl nearly to the ottom of thejar 1, and which at its upper-y or outer end is ada ted to be connectedwith a rubber tube an said rubber tube is adaptedto' be connected with a suitable air/pressure device, preferably an lordina foot bellows,1such as may be ,ob-'l tained om dental suppl houses.

The lower or inner en of the tube 5 .has

connected thereto a distributing device, consistingof a perforated drum 7 of copper, or other suitable metal, through which the forced` air passes and commingles with the ether, as will be understood. The top plate 8 of the perforated drum islcentrally perforated to receive the lower end of the tube 5, as'clearly illustrated in Fig. 1.

fThe aerated ether from the vessel 1 next passes through a heater whereit is further rareiied, and in which condition is administered to the patient. The heater consists of a suitable metallic vessel 13 having a fixed cover plate 14, that is perforated to receive tubes 15 and 16,*and a plug 17. The tube 15 connects, by a rubber tube, 15, with the short tube 18 that passes through the aperture 19` of the stopper 3, and provides the outlet for the air and ether. Thebody of the tube 15 lis constructed with a .spiral tube 20, that is wound around vand in close contact with a cylindrical vessel 21, and with which it communicates at the point 22. The vessel 21 issupported substantially centrally within the vessel 13 through the medium of the tubes 15 .and 16, and the space between said vessels 13 and 21 is filled with sodium l acetate 2.3, JNwhich constitutes the heat retaining medium for the aerated ether that enters within the vessel 21'at 22, and passes therefrom through the pipe 16 .to the mouth piece, mask, orv cone to be applied to the patient..

The sodium acetate or other material used is placed in the vessel 13 through the opening in the cover plate 14, that is normally closed by the screw, plug 17. ,Y

f For convenience in carrying the apparatus and holding the vessels "1f and 13 thereof in proper relative relation, a `tray'i's provided and the same consists of a supportlng plate' bottlell and tighten the sto per 3. The

heater is then to be placed in oiling water for from ten to fifteen minutes when con- .105

nection is made between the tubes 15, and .'18 ofthe heater and ether bottle. Air is then forced through -the` tube'and the aerated ether caused -toff pass through the `tubes 20 the heatmg chamber 21, which by this time has become suciently Lheated through the sodium acetate, and in this condition passes through the pipe 16 to the patient, as will be understood.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spiritof my invention, and therefore I do not wish to be limited to such features except as may be required by the claims.

What AI claim is z- A heater for use in apparatus'for administering anestheltics, comprising a Vessel adapted to be heated from an external source, a closed Vessel located within the first-named vessel, a pipe entering the firstnamed vessel and formed with a spiral surrounding the second-named vessel, the 1nner end of said spiral pipe entering and communicating with the chamber of said 20 second vessel adjacent the bottom thereof, a second pipe passing through the first and second-named vessels and communicating With the chamber of the latter at the top stance within the space between said Vessels adapted to maintain the temperature within the chamber of the second Vessel whereby to. vaporize the aerated anesthetic liquids, substantially as described.

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

B. G. WOLF,

HENRY HOFFMANN.
