HOLDER FOR GAS INHALERS UNITED v"STATES,
VILLIAM H. GILBERT, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO PATENT OEE1cE.
THE S. S. VHITE DENTAL MANUFACTURING COMPANY, OF SAME PLACE.
HOLDER FOR .GAS-INHALERS.
SPECIFICATION forming part of Letters Patent No. 340,778, dated April 27. 1886.
Application tiled January 8, 1885. Serial No. 152.330. (No model.) l
To all whom it may concern.-
Be it known that I, WILLIAM H. GILBERT, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful .Improvements in Holders for Cylinders Containing` Nitrous-Oxide Gas, ol' which the following is a specication.
The antest-hetic nitrous oxide, whichis widel y used by dentists to produce amestliesia,is usually condensed into a liquid form in a cylinder, which is shipped from the factory to the dentist or surgeon for use by him in the form of gas to produce amesthesia in a patient. It is usual in the use of this anzesthetic, when an operation is to be performed, to connect a rubber bag with the cylinder and draw off, in the form otl gas, a suiiicient quantity toproduce the result desired when breathed by the patient. These bags, of standard size or dimensions, hold about live gallons, and it is customary to fill the bag with gas and then detach it from the cylinder and convey it to the point where the patient lies or is seated-for instance, in the dentist7s chair. It frequently happens that the amount of gas in the bag is insuiiicient to produce perfect anaesthesia in the particular patient under operation, and as there is no time to attach the bag to the cylinder and replenish it with gas the result is not produced. In order to have the cylinder conveniently at hand it has been mounted in a stand or holder resting upon the ioor near the operators chair; but this, while having the advantages in one direction,is objectionable in other directionswfor instance, it is in the way of the operator in moving about the operating-chai r. Inasmuch as the patient cannot inhale the gas directly from the cylinder and thc use of a bag or reservoir between the cylinder and patient is therefore necessary, it' is very desirable to have the bag and cylinder so connected and so organized that if the capacity of the bag is exhausted without producing anzesthesia it may be instantly replenished and au additional supply of the gas furnished the patient to produce perfect insensibility, and it is also desirable that the apparatus be so located as to be out of the way of the operatorin moving about his chair.
To attain these desirable ends is the object of my invention,which consists in the peculiar organization and combination of parts particularly described below, the improvements claimed herein by me being then particularly recited in the claims at the close of this specification.
In the accompanying drawings, Figure l is a perspective view of my improved apparatus mounted upon a wall plate or bracket attached to the window framing or wall of the operating-room. Fig. 2 is a View in elevation of my improved arrangement, showing a portion of the holder or bracket for the gas-cylinder in section. Fig. 8 is a horizontal section through a portion of the bracket and cylinder on the line 3 3 ofFig. 2; and Fig. 4 is a view of a portion of the apparatus, showing more espeeially the inhaler at the free end of the usual inhaling-tube as seated in its holder, which preferably constitutes a part of my improved apparatus, as will be hereinafter set forth.
The wallplate A is attached to the windowframing, or to a board or support which may be attached to the wall, preferably by means of screws a a, and bolted to this wall-plate are two rings, B B, arranged one above the other in the same vertical line substantially. The upper ring, B, has an opening somewhat larger than the external diameter of the gas-cylinder C, while the lower ring, B', is provided with a seat,'b, upon which the bottom of the cylinder C rests when inserted through the upper ring, B. Said ring B is provided with projecting points or ribs b b2 and with a elampscrew, bwhereby the cylinder may be readily inserted in its holder and the clamp-screw then tightened up or adjusted to support the cylinder in a true vertical relation in the holder or bracket, as will be apparent. \Vhen the cylinder C is in position in the holder, the clampscrew is tightened, so as to fasten the cylinder securely in place, while obviously it may be readily detached when the cylinder is to be again lilled with the liquid nitrous oxide. The cylinder C at its upper end is provided with a valve, which may be opened to permit the liquid to escape in the form of gas through a pipe, D, and into the gas-bag E, and thus fill said bag with the gas which is inhaled by the patient when the operation is to be performed and anaesthesia produced. The bag E is thus connected with and virtually forms a part of IOC the cylinder C, and inasmuch as this cylinder is mounted in the holder attached to the window-framing or wall, it is removed from the way of the operator in moving about the operating-chair, while it is conveniently close to the operator to be instantly replenished by opening, for instance, the stop-cock d in the pipe D, if the first supply of gas to the bag is not sufficient to produce anaesthesia. Connected with the gas-bag is the usual flexible inhaling-tube, F, carrying at its outer or free end the mouth-piece or inhaler G, as to the construction of which I claim nothing as new herein.
Forming a part of the pipeD or connection between the gas-bag E and cylinder C is a yoke, I-l, in the fork of which the inhaler may be placed when not in use, so as to support it out ofthe way and retain it in position'to be readily disengaged for use. The valve C of the cylinder C is a valve made to stand considerable pressure, usually about' eight hundred pounds to the square inch, and is the main valve by which the condensed or liqueiied gas is permitted to escape through the pipe D into the gas-bag.
For the purpose of replenishing the gasfbag and to permit of instant operation I provide a stop-cock, d, inthe pipe D for this purpose. This permits of instantly opening the pipe D to permit of the bag being replenished by gas from the cylinder C if the lirst filling of the bag should prove insufficient to produce in the particular patient the result desircd-to wit, perfect antesthesia.
The advantages of my i mprovemcn ls are, that the apparatus is one entire connected apparatus, that it is mounted out ot' the way of the operator, and that it permits of instantly replenishing the bag with gas when it has been once emptied in the operation of producing insensibility. Ihe inhaler and tube through which the gas is breathed by the patient may be also hung in position to compact the apparatus,while permitting ofthe ready disengagement of the inhaler when an antesthetic operation is to be produced.
I claim herein as my invention- 1. A holder for aniesthetic-containing cylinders,consisting of a wall-plate, a ring at the upper end of said plate, and a ring or rest having a support for the cylinder' to rest upon at the lower end of said plate, substantially as d scribed.
2. holder for anzesthetic-containing cyl-V indersqgnsisting of a wall-plate, a ring at the upper end of said plate having internally-pro jecting pointsV or ribs, and also iitted with a clamp-screw working therethrough, and a ring or rest at the lower end of said plate, containing a seat for the lower end of the cylinder,sub stantially as described.
3. The combination,in an antesthetic-administering apparatus, of the antesthetic-containing cylinder, the gas-bag, the rigid pipecon nection between and supporting the gas-bag from the upper end of said cylinder, the valve in the upper end of said cylinder, andthe stopcock in said pipe-connection between said Valve and the gas-bag, substantially as described.
In testimony whereof I have hereunto subscribed my name.
VILIJIAM H. GILBERT.
