I ui saI JAMES G. POE, F DALLAS,` TEXAS.

Timon: ATUBE.

application inea November 7, 1921. serial No. siam.

To all whom z't may cof/wem.'

Be it known thatI, JAMES G. Pon,-a citizen of the. United States, residin at Dallas, in the county of Dallas and tate of Texas, have invented certain new and useful Improvements in Throat Tubes; and I do declare the following to be a full, clear, and exact description of the invention, such as -will enable others skilled in the art to which it appertains to make anduse` the same. i

This invention relates to an improved device to be used while operating and one object of the invention is to provide a device which may bel readily put in place and removed, one portion thereof being placed between the teeth and forming a prop to hold the mouth vopen while ananesthetic is being administered vand the second portion being passed through the prop element after the patient has been rendered unconscious by the anesthetic. By havi'gthe `'prop put in place before the person is anesthetized, the-teethare prevented from contacting and the tube may thus be very easily put in place with its innerend porn tionextending into the throat;

Another'object of. the invention is to prof vide Ia device in which the tubular body which is to be inserted through the prop into the throat will be lprovided with spaced longitudinally extending conduits which terminate at their outer ends in tube extensions curved towards the sides so that rubber tubes connected with these tube extensions will' not be bent and free passage through the tubes prevented.

Another object of the invention isto provide a device of the character described in'- which the tubular body may have the conduits in spaced relation and this tubular.

body-v provided adjacent its inner'end with a side openin terior of the ody between the conduits.

vide a device which will be so constructed that it will be firmly iheld in place by the teeth land will have notendencyjto rotate Sltion. ,l

` duce.and which may be'veryeasily cleaned and kept sanitary.

This invention 1s lllustrated in the accompanyingdrawing, wherein:

Figure 1 is a view showing the device parcommunicating with "the in- Another obj ect of thefinven'tion is to protiallyl in planand partially inlongitudinal section.

' Figure 2 is a view showing the device in side elevation.

Figure 3 'is a view showing the device in end elevation.

Figure 4i is a longitudinal sectional view through the dev-ice.

Figure 5 is a perspective view of the prop element.

Figure 6 is a sectional view through the prop element.

' Figure 7 is al transverse sectionalvview through thetubular body.

This device'includes a prop element to lhold the mouth open and a tubular member band 2 also serves to prevent the device from easily slipping as it ermits of thedevice being firmly grippe A collar 3 is provided vatl the outer end of the tubular body forengaging the lips or gums and preventing .the prop from-rmoving into the mouth beyond -a desired distance.

,The tubular member 4 which is to -be passed'through the prop and back through the mouth into thefthroat is .provided with 'a 'collar 5 at its -outer end for engaging.

the collar 3 and thus limiting inward move- 'ment of the tubular member 4: and preventing it from accidentally slipping through the` rop and moving too far into the ,throat whi e' an operation is bein performed. This tubular member 4 con orms to the shape of the flattened tubular body 1 andis vprovided with yconduits 6' which extend longitudinally of .the tubularr` member through th'eside portions thereof as shown in' Figs-1A and 7.f These conduits extend fromthe inner end o f the. tubular member to the outer end thereof and terminate in tube extensions 7- which extend forwardly i from Ithe outer ends thereof and are curved towards the sides. 4"Ih'esetubes 7 have their outer end portions provided with enlargefirst beput`in place and will be held between the teeth.. The anesthetic will then be ad! ministered until the patient is unconscious and the tubular member will then be passed through the prop and will have its curved yinner end portion extending into the throat. With this prop in place, .the tubular member can be easily inserted without it being necessary to pry thetceth apart. A rubber hose leading from a bottle of vaporized ether may be connected with one of the tubes 7 and a rubber pipe leading from a vacuunr pump may be connected with the second tube 7. It wilLthus be seen that mucus and blood may be drawn out through one of these tubes 7 and. the anesthetic administeredA through the second. The patient may breathe through the main passage ofthe tubular member between the conduits 6. The opening l0 reduces the liability of this tube Ll being closed at its inner end. After the operation is coii'ipleted, the device can be easilyueinoved, the prop being left in place,

I claim:v

Yl. A. device of the character described comprising-a flat tubular body constituting until the )atient (vains consciousness.

.a jaw prop for insertion between the teeth to hold the mouth open, and' an open-ended tubular'meniber flattened to conform to theY contour of the tubular body in cross section and slidable through said same for insertion Ainto the mouth and throat after a patient has been anesthetizedwith the prop in place between the teeth, the tubular member being held against rotation by the flattening of the tubular body and member,

bular igieaeio4 2. A. surgical devibe comprising a tubular body constituting a jawlprop for insertion between the teeth torhold the mouth open,

' engagement with the tubular member to hold thesame against rotation whenpositioned inthe tubular body.

3. The structure of claim 2 having the tumember provided with 'conduits formed integral therewith and extending longitudinally through the same in spaced relation to leave a breathing space between the conduits, said conduits terminating in tubes extending from thev outer end of the tubular member'.

ll. The structure of claim 1 having the tubular member provided with conduits eX- tending longitudinally through the saine aiidterminating in tubes extending from the outer .end of the tubular' member and curved towards the sides, the conduitsv being in spaced relation and the tubular member having one of its walls provided with an opening adjacent its inner end.

5. A surgical device comprising atubulai' b'o'dy provided with a side port adjacent its inner end'and opening through the side ot the body, and open-ended Vconduits extending longitudinally lthrough vthe body with the side port positioned between the conduits. l

6. A surgical devicecomprising a tubular body provided'with a side opening adjacent its inner end and opening through the side of the body,` and conduits extending longif tudinally through the tubular body upon opposite sides ofthe side opening and termi-` nating i'ii tubes extending from the outer end of the body.V

.In testimony whereof l have hereunto set my hand.

JAMES Gr. PUE.
