ANIMAL ANES'IHETIC APPARATUS.
Specicaton of Letters Patent. Patented Sept. 111, 191'?.
Application filed February 16, V1917. `Serial No. 149,001.
'To all whom t may concern:
Be it known that I, GEORGE M. DORMAN,
a citizen of the United States, residing at No. 1011 Felix street, in the city of Saint Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Animal Anesthetic Apparatus, of which the following is a specification.
The object of my invention is to provide a device by which to anesthetize an animal in order to eliminate pain during an operation.
I accomplish my object by the mechanism hereinafter described, in which:
Figure 1 is the side view of the vaporizer which saturates the inspired air with either ether, chloroform or ammonia, or furnishes the animal with straight air.
Fig. 2 is a top view of Fig. 1.
Fig. 3 is the side view of the air tight mask compelling the animal to inspire the air through one tube and expire it through another tube.
Fig. 4. is a front view of Fig. 3.
Fig. 5 is a detail of the check valve on the vaporizer.
Fig. 6 is a front view of the indicator board.
Similar letters refer to similar parts throughout the several views, the letter D indicating a mask made of metal in the form of a cone and being provided with a sheet rubber front E having an elastic band E which forms a central circular opening E2 to receive an animal muzzle; an expiration valve F is located on the top of said metal mask and an intake tube F is located on the opposite end from said rubber front and circular central opening. A vaporizer consisting of three graduated glass containers A, B and C, contain ammonia, ether and chloroform, respectively, each being connected with a tube, G, G and G2, supplied with a cut-ofi1I valve H, H and H2, and connected with one main tube, I, placed in horizontal position; this main tube, on one end of which is a cut-ofi valve I', is for supplying straight air. On the opposite end of the main tube from the air valve there is a check valve, J, to permit the air or vapor to pass toward the animal. Each container is provided with an air-tight lid, K, L and M, which allows the passage of one of said tub'es, G, G and G2, supplied with said cutoff valve H, H and H2. The lid also admits 'ofY the passage of two smaller tubes A', A2 in A, B and B2 in B and C and C2 in C, which are set in lids K, L and M air tight and which pass down into the container to the bottom of said container A, B and C. The lowest one inch of tubes A', A2, B', B2 and C, C2, are perforated with small holes, zlz. Each of said 'cut-off valves is supplied with a stem N and an indicator to show Whether it is open or shut. O is a non-collapsible rubber tube connecting the vaporizer at J with said mask at F.
In operating my invention the mask is placed over the animals muzzle and the tube is connected to the mask and vaporizer. If the anesthetic is to be given and chloroform is used the valve on the tube which connects the main horizontal tube with the chloroform container is open and the rest of the valves are closed. On inspiration of the animal the air from the chloroform container is drawn out and to supply this air, air will pass through said smaller tubes and through said perforations and will bubble up through the chloroform liquid saturating it with vaporized chloroform. On the next inspiration of the animal the air it receives will be saturated with the chloroform vapor. These inspirations are repeated until the animal is anesthetized to the extent deemed necessary by the operator; then the chloroform valve is closed and the straight air valve is opened. Should a stimulant be wanted the valve on the ammonia container can be opened and the vapor from the ammonia can be administered in the same way as the administration of the chloroform has been previously described. Should the 0perator want to use ether for the anesthetic it can be administered in the same way as previously described in the chloroform anesthesia. All expirations are checked at the check valve on the horizontal tube of the vaporizer, but must pass out through the expiration valve situated in the mask.
What I claim and desire to secure by Letters Patent, is:
The combination in an animal anesthetic apparatus, of a mask in the form of the frustum of a pyramid, a rubber curtain fastened on all sides of one end of said mask and having a central opening, an elastic band around the central opening, an expiration valve on one side of said mask, an inspiration tube on another side of said mask, three graduated glass containers to contain.
