SPECIFICATION forming part of Letters Patent No. 743,294, dated November 3, 1903. Application and June 19,1903.l sentire. 162.289. (No man.)
the county of Berks, England, have invent-1 ed new and useful Improvements in Apparatus for the Administration of Anesthetics, ot"
which the following is a specification.
This invention relates, to an improved apparatus for the administration of anesthetics While applicable for a number of analogous purposes, it is espe-` cially` designed for the convenient adminis` to the human subject.
tration of soemnoforme and other like preparations, including nitrous-oxid gas.
The apparatus is constructed, preferably, as follows: A rubber bag of suitable dimensions is attached to an elbow-tube of metal. The other end of the elbowpipe terminates in a funnelshaped nozzle formed partly of metal and partly of celluloid or other convenient material. The edge of this funnel'- shaped projection issurrounded by a pneumatic tube provided with a suitable valve for inflation. This tube when inflated tits around the mouth and nose of the patient in close contact with the face and insures that the anesthetic is properly inhaled. The inside of the funnel is lined with a loose piece of" lint or other suitable material cut to shape, upon which the anesthetic is sprinkled. The lint is held in place by means of a wire ring and guard, which protects the mouth of the elbow-tube and by means of projecting wires holds the lint firmly in place. This guard is removable and can be instantaneously taken oft' whenever it is needful to removethe lint.
A special feature of this device consists in the means tor admitting a regulatable quantity of air during inhalation, thusobviating the necessity of occasionally removing the face-piece while producing anesthesia and also of the administrator inlating the bag with his own breath before presenting the anesthetic. This is effected by means of an aperture, preferably in the upper part of the elbow-tube, which aperture is controlled by a slide worked by a projecting handle in such a position `as to be readily manipulated by the person administering the anesthetic. By this means any desired quantity of air can be immediately supplied to the patient, and the eifect of the anesthetic is thus retained under control.
In order to make the invention clear, the same is illustrated, by way of example, in the accompanying drawings, in which- Figure 1 shows a front view of the facepiece; Fig. 2, a side elevation, in partial secvery suitable material for the purpose.V
Around the edge of the celluloid funnel l I arrange the pneumatic rim 2, provided with a rubber tube 3, connected to a stop-cock 4, with nozzle or other eqnivalent arrangement whereby the rim can be inliated or deiiated at will; The funnel l of the face-piece is secured at its apex in the metal socket- 5, which screws upon the angle-tube 6, provided with the air-inlet 7 and valve 8. (Shown more in detail in Figs. 4 and 5.) The angle-tube 6 is soldered to the socket 9, provided with a slightly-ribbed extension adapted to receive the mouth of the rubber bag l0. This bag has a suitable elastic ring at its mouthpiece, whereby an air-tight junction is eected with the metal tube 9, and is further secured by a loose rubber ring ll. side and outside a loop or the like 12 and 13, respectively, for the purpose hereinafter described. n
Returning now to the face-piece, the same has a removable lining of some absorbent material, such as a loosely-woven iiannel orlint or any other suitable fabric or substance,upon which the anesthetic is sprayed. This anesthetic, as stated, is preferably soemno'forme. The apparatus may also equally Well be used with kelene, chlorid of ethyl, and other liquid anesthetics, or by means of a hollow vulcanite or other suitable connection (not shown in the drawings) in the same position and in place of the loops 12 13 a supply of nitrous-oxid gas may be introduced within It has, further, both ini ICO the face-piece. The apparatus, however, remains the same in anycase. The lining aforesaid is held in place by a frame of springwire 14, which presses gently against the sides of the face-piece and holds the lint or flannel or the like securely in place. At the same time the spring-wire apparatus is removable at any time when it is desirable to change the fabric.
The air-hole 7 is calculated to admita maximum quantity of air which it may be desirable to allow the patient to inhale, and by meansl of the valve 8 the exact amount of opening of the air-hole is regulated.
The bag 10 is secured upon the tube 8 by means of the elastic ring l1 aforesaid or other suitable grip. This bag is adapted to be readily turned inside out and is for this purpose provided with strong loops or the like 12 or 13, attached to its bottom. In order to reverse the bag, itis removed from the elbowpiece and the inside loop or the like caused to approach the orifice, when it can easily be taken hold of and drawn through the oriiice, thus turning the bag inside out, the ring 1l having, of course, been previously removed. By this means it is possible to maintain perfect cleanliness of the apparatus and rapidly to prepare the same for use by another patient after each administration.
l. In combination in apparatus for administering anesthetics, a face-piece, a iiexible rim on said face-piece, absorbent material within said face-piece, means for regulating the air-supply, a rubber bag attached to said face-piece, a constricting device on the neck of said bag, and meaps for reversing said bag.
2. In combination inapparatus for administering anesthetics a funnel-shaped non-absorbent face-piece, a pneumatic rim on the outer edge of said face-piece, a loose lining of absorbent material in said face-piece, a spring-holder adapted to press s'aid absorbent material against the sides of said face-piece, the connecting-tube 6 attached to said facepiece, means for controlling the air-supply in said tube and a reversible bag attached to said tube. Y
3. In combination in apparatus for administering anesthetics, a face-piece, a iiexible rim on said face-piece, absorbent material within said face-piece, a tubular connectingpiece having a nozzle adapted to engage with a rubber bag, the bag lO, the constrictingring l1 adapted to secure the neck of the bag on the nozzle of the tube, and the projections 12, 13 for reversing the bag in either position.
4. In combination in apparatus for administering anesthetics the funnel l forming a face-piece, the metal socket 5 attached to said funnel, the angle-tube 6 attached to said socket, the wire frame 14 Within said funnel adapted to hold lint or the like, the pneumatic rim 2 on said face-piece, the rubber bag lO adapted to engage with the tube 9 and the constricting-ring 11 adapted to secure the neck of the bag on the nozzle of the said tube.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
