"ORO-PHARYNG~AL SUCTION AIRWA~"
Technical Field lS This invention relates to an oro-pharyngeal airway and more specifically provicles an airway operable to permit fluids, mucus, blooc3 or vomitus material to be evacuated from the pharynx without removal of the airway from the patient's ~outh, to ~ permit insufflation of the patient's lungs and to permit normal breathing of the patient while the airway is in place.
Background Art The prior art includes a number oE airway desicJns operable for providing an airway into a patient's throat area to permit air to enter and escape during normal breathing. ~lowever, durin~3 certain medical conclitions, such as following general anesthesia, comatose, emer~ency conditions or in newborns, it is necessary to develop suction in the patient's throat to remove fluids, mucus, blood or vomitus material. In using most of the prior art airways, the airway must be removed and a ca~heter tube inserted in the patient's throat area to perform . . "~
the suction operation. Also, most prior art airways must be removed before insufflation of a patient can be effected, unless an oxygen mask or nasal oxygen -tube is used. Although certain prior art airways provide a passageway for insertion of a suction tube to evacuate the throat or pharynx, none has provided an integral suction passageway for connection to an external suction apparatus or oxygen supply.
Summary of the Invention Briefly, the present invention comprises a suction airway defining a breathing passageway as well as a conduit for connection to either a suction means or an oxygen supply means which can be easily attached to the conduit without removing the airway.
More particularly, the invention pertains to an oro-pharyngeal suction airway comprising an elongate body adapted to extend from a forward end thereof adapted to be engaged by a person's mouth to a rearward end thereof adjacent to the person's pharynx. The body includes enclosed elongate conduit means extending along -the length of the body and open at the forward and rearward ends thereof. Means define an elongate airway for breathing by the person, adjacent to the conduit means, and means is located at the forward end of the conduit means for receiving an operative connection to a pump means without obstructing the flow of air through the airway means.
In one aspect, the airway means is defined by a plurality of flanges extending away from the conduit means to form at least one channel.
In another aspect the airway means is defined by a pair of parallel flanges, the flanges being fixed to opposite sides of the conduit means so as to define a pair of channels bounded by the flanges and the conduit means.
In a still further aspect, the airway means is defined by four elongate radial flanges extending radially away from the conduit means, with two parallel bridging flanges each attached to two of the radial flanges so as to form two enclosed air passageways and two open air channels.
~ .
2a In still another aspect the forward end of the conduit means defines a radial suction control opening therein.
In a preferred embodiment the body fur-ther includes a pair of parallel flanges defining a straight forward section and a curved rearward section, the flanges being held in spaced apart relation at the straight section by a rigid conduit attached to the flanges, and at the curved section by a plura]ity cf longitudinally spaced apar-t, laterally staggered tab elements.
The flanges define lip elements at the forward ends thereof for engaging the outside of a person's mouth, one of the lip elements defining a radial suction control opening therein in communicat-ion with the interior of the rigid conduit. A flexible conduit extends along the body between -the flanges and between the staggered tab elements to be frictionally received within the rearward end of the rigid conduit. The rigid conduit defines at its forward end a tapered end for frictionally receiving a tube connected to a pump means.
The airway of the invention will function only as an airway during certain conditions, and will function as a combination airway and pharynx evacuator when necessary.
The invention also provides a pharynx evacuation system which can be used in combination with a standard anesthesia mask and connection means and can be used with patient insufflation systems.
These and other aspects and advantages of the details of construction will become apparent after reading the follow-ing description of the illustrative embodiment, with reference to the attached drawings.

Detailed Description Referring now in more dçtail to the drawing, in which like numerals represent like parts throughout the several views, Fig. 1 shows a side elevational view of an oro-pharyngeal suction airway 10 embodyinq the invention. The suction airway 10 includes an elongate body 11 formed of a suitable rigid material, such as a lightweight plastic that can be in~ection molded into the desired shape. The body 11 includes a forward straight section 12 and a rearward curved section 13 defined by a pair of longitudinally extending parallel flange elements 16 and 17. The 1ange elements 16 and 17 are held in spaced apart relation by a plurality of tab elements ``

- 18 that are preferably formed inte~rally with tlle flange elements 16 and 17. The tab elements L8 are preferably conveniently spaced along the lenqth of the body 11 on alternatlng sides of the centerline of the flange elements ]6 and 17.
Also separating and supporting the flanqe elements 16 and 17 at the forward end of the body 11 is a ri~id conduit section 21 Eixed to or integra]ly formed with the flange elements 16 and 17. The conduit section 21 extends rearwardly between the flange elements 16 and 17 for the greater portion of the straiqht section 12 of the body 11. The conduit section 21 also extends forwardly to terminate in a nipple element 22 having a tapered shape to receive 1~ and frictionally retain a tubular conduit 30, as shown in Fig. 4, the tube 30 being connected to a suction pump apparatus ~not shown). The nipple element 22 is also shaped to terminate at its rearward end in a shoulder 2~ that provides an ~ annular sealing flange to matinqly receive a complementary opening formed in a standard anesthesia mask (not shown).
In the preferred embodiment o~ the invention, as shown in Figs. 1-3, a length of flexible tubing 14 is inserted from a rearward end oE
the curved section 13 longitudinally alonq the center of the body 11 between the tabs 1~, until the forward end 15 of the tube 14 enters the conduit section 2l and extends therein for a portion of the length oE
the conduit section 21. The penetration of the tube 14 into the conduit section 21 is shown in dashed lines in Fiq. 1. As a result, the tube 14 and the conduit section 21 form a continuous passageway between the extreme ends of the body 11. Thi,s passageway can be used to evacuate fluids from the - patient's throat or to insuf~late the patient's lungs by connection of an appropriate suction or oxygen supply tube to the nipple 22. At the same time, the parallel flange elements 16 and 17 extend beyond the dlameter of the tube 14 ancl the tabs 18 so that the cross section of the suction airway 10 is in the form of an "H", as shown in Fig. 3. It will be seen that a pair of sidewardly opening channels 19 and 20 are formed by the flange elements 16 and 17 and the tube 14. The channels 19 and 2~ provide airways through which the patient can breathe, as will be explained in detail hereinafter.
Referring again to Fig. 1, the flange elements 16 and 17 terminate at the middle portion of the conduit section 21 in a pair of lip elements 23 and 24 extending at right angles away from the conduit section 21 and then extending forwardly and toward the conduit section 21 to form arcuate elements 23a and 24a, respectively. The arcuate ~ portion 23a is connected to the exterior of the conduit section 21 by a connecting block 27, and a vent opening 2~ extends downwardly throuqh the arcuate portion 23a, the block 27 and the conduit section 21 to communicate with the hollow interior of the conduit section 21.
To improve the suctioning or aerating capa~ility of the suction airway 10, a plurality oE
openings 29 can be made radially into the sides of the tube 14 adjacent to its rearward end, as shown in Fig 1.
In operation of the oral pharyngeal suction airway 10, the device is inserted into the patient's mouth until the curved rear section 13 extends into the back of the patient's throat adjacent to the pharynx. The lip elements 23 and 24 are placed ,. ~

- aqainst the outer surface of the patient's lips and the patient is instructed to bite down on the forward straight portion 12 of the flange elements 15 and 17, as shown in Fig. 4. At this time, the patient is able to breathe through the airways defined by the channels 19 and 20. If no other apparatus is connected to the nipple 22, then the patient can also breathe through the tube 14 and conduit section 2l.
In the placement of the suction airway 10, the attending person can grasp the arcuate portions 23a and 24a with the fingers in order to contt-ol the location of the suction airway 10.
~hen it is necessary to perform a throat evacuation to remove fluid, mucus, blood or vomitus material from the throat, a flexible tubular conduit 30 is frictionally engaged over the prOJeCting nipple 22. A suction pump apParatus also connected to the tube 30 is operated to create suction within the tube 14 to withdraw such fluids from the patient's throat.
~ This can be accomplished without removing the sUCtiOIl airway 10 from the patient's mouth. Alternately~
insufElation of the patient's lungs can be accomplished by connecting the tube 30 to an oxygen supply apparatus in order to pump a stream oE oxyqen out o~ the end of the tube 1~ down the patient's throat to the patient's lungs. ~urinq either suction or oxygen supply operations, the patieilt is stil]
able to breathe through the channels 19 and 2n. The vent opening 28 can be used as a valve to contr~l the strength of suction by means oE the attending person's fingertip closin~ oEf all or a portion of the opening 28. IE continuous full strength suction is desired, the opening 28 can be plugged with a rubber stopper (not shown) or the like.
~ second embodiment of the oral-pharyngeal 7~
-- suction ai~way embodying the present invention is shown in Figs. 5 and 6, desiqnated by the reference numeral 110. The suction airway 110 includes a cylindrically shaped central conduit 114 be(3inning in a nipple portion 13 and ext:ending rearwardly throuqh a straight section 111 followed by a curved section 112. Four longitudinally extending flange elements 115, 116, 117 and 11~ pro~ect outwardly l~rom the central conduit 114. Four airway channels 130, 131, 132 and 133 are thus defined between ad~acent radially extending flanges. If desired, the suction airway can be utilized as just described, with the patient biting down directly on the radially extendinq flanges 115-118. However, the suction airway 110 preferably includes a pair of parallel brid~3ing flanqes 119 and 120 (analogous to flanges 16 and 17 in Fig. 1) which bridge the ra~ially exten(ling ~langes 115 and 116, and 117 and 118, respectively, as best shown in Fig. 6. The parallel flanges 119 and 120 extencl from the rearward end of the curved section 112 to a point ad~acent to the nipple portion 113, at which point the flanges extend at right angles away from the conduit li4 to form lip elements 121 and 122. It will be seen that the airways 131 and 133 are enclosed airway channels, whereas the airways 130 and 132 are open channe]s.
Operation of the second embodiment oE the invention shown in Fig. 5 is accomplished in a manner similar to that described Eor the first elnbodiment shown in Fig. 1. Suction or insufflation is provided through the conduit 114 by connection of a suction apparatus or oxygen supply apparatus to the nipple portion 113. The airways permit the patient to breathe while the suction is operating. ~ ring 123 can be provided on the forward surface of one of the .. ..
-- lip elements 121 and 122 to provide a means for graspinq the section airway 110 for placement in the patient's mouth and for permittinq the section airway 110 to he stored on a hook.
A th ird embod ime n t 1 5 0 o f the oro-pharynqeal suction airway of the invention is shown in cross section in Fiq. 7, looking t~ward the forward end of the apparatus. ~ central conduit 1~1 has extending therefrom four radial E]anges 152-155.
No bridging flanges are present in the emhocliment of Fig. 7, but the radial fLanqes 152-155 form open airway channels therebetween and terminate in lip elements 161 and lh2, which function in the same manner as the lip element described in connection with the other embodiments. In other respects, the airway shown in Fig. 7 is similar to the first and second embodiments described above, with the exception that flanges 152-155 are not separated by right angles. The angle between flanges 152 and 154 ~ and between flanges 153 and 155 is smaller than the angle between flanqes 152 and 153 ancl between flan~es 154 and 155.
It will be understood by t:hose skilled in the art that the above-described embodiments of the oro-pharynqeal suction airway of the present invention can be constructed of various materials, so lonq as the portion of the apparatus onto which the patient bites is sufficiently rigid so that it will not readily collapse under the pressure of the patient's jaws. The various elements of the suction airways can be made separately and attached together, or can be integrally molded by well known injection moldinq techniques. For example, the flexible tube 14 that is disclosed as bein~ inserted into the body 35 11 of the embodiment 10 shown in Fig. l can be an 7;~
integral conduit formed at the same time as the remainder oE the body 11. In this case, the tabs 1 would not be necessary.
While this invention has been decscrit~ed in detail with particular reference to preferred embodiments thereo~, it will be understood that variations and modifications can be effected within the spirit and scope of the invention as described hereinbefore and as defined in the appended claims.
