By M
ORO-PHARYNGEAL SUCTION AIRWAY Carol A. Elmore, Miami, Fla., assignor of fifty per cent to Ursula Z. Janis, Coral Gables, Fla.
Application December 8, 1953, Serial No. 396,920
4 Claims. (Cl. 128-351) This invention relates to an oro-pharyngeal suction airway and more specifically provides a device for permitting the suction of mucous, blood or food particles from the pharynx without removal of the airway from the mouth.
An object is to provide a device with a curved tubular member and a smaller metallic tube disposed therein wherein continuous suction may be maintained for aspiration of the throat without removal of the airway.
Another object of this invention is to provide a suction airway device having a rigid metallic tube therein for receiving a flexible catheter which is easily passed through the metallic tube without kinking or bending thereby permitting continuous aspiration of the throat.
Yet another object of this invention is to provide a suction airway which permits constant removal of mucous, food particles and other secretions which tend to obstruct the throat of a person receiving anesthesia.
A still further object of this invention is to provide a suction airway which is easy and eflective in removing mucous from the throat and which permits easy insertion of a catheter and assures the operation of the catheter.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a perspective view of the ore-pharyngeal suction airway of the present invention;
Figure 2 is a transverse, vertical section taken substantially along section line 2-2 of Figure 1 showing the details of construction of the outer tubular member, the elongated metal tube and the short metal tube secured to the long metal tube;
Figure 3 is a longitudinal, vertical section taken substantially along section line 33 of Figure 1 showing the details of construction of the tubular member and the relative thicknesses of the upper wall and the lower wall thereof;
Figure 4 is a bottom plan view of the present invention with portions thereof broken away; and
Figure 5 is a perspective view showing the metallic tube and the short tube secured at one end thereof.
Referring now specifically to Figure 1, it will be seen that the numeral generally indicates the oro-pharyngeal suction airway of this invention which includes an elongated semi-flexible and concaved tubular member 12 which includes a generally curved portion, a short straight portion 14 and an outwardly extending flange 16 on the end of the straight portion 14. The flange 16 and the tubular member 12 are generally elliptical in cross-section and the upper wall of the tubular member 12 is generally thicker than the lower wall thereby retaining the concave curvature of the tubular member 12. A metallic tube 18 curved in the same manner as the tubular member 12 is positioned in the tubular member 12 at one side of the elliptical cavity therein. A short elliptical tube 20 is secured to the straight portion 22 United States Patent 0 2,705,959 Patented Apr. 12, 1955 of the elongated tube 18 and fits into the elliptical cavity of the straight portion 14 of the tubular member 12 at the flange 16. It will be seen that the short tube 20 and the elongated tube 22 completely fill the cavity of the straight portion .14 of the tubular member 12. It will be understood that the suction airway 10 may be placed in a persons mouth with the end thereof projecting downwardly into his throat adjacent the pharynx while the person is receiving anesthesia. If the patient who is receiving the anesthesia has his throat filled with mucous or other obstructions, a catheter tube may be inserted through the metallic tube 18 thereby removing the mucous or other obstruction from the patients throat thereby preventing interference from the patients normal respiration by the obstruction.
It will be seen that this device permits the use of a catheter tube without removal of the tubular member 12 from the patients throat, thereby assuring that the catheter tube will be at all times in an operative condition regardless of whether the patient may bite down upon the suction airway 10. The tube 18 is constructed of any suitable metal alloy and the tubular member 12 may be constructed of rubber-like material or any well known plastic having the necessary requirements of sanitation and sterilization.
From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
What is claimed as-new is as follows:
1. An ore-pharyngeal suction airway comprising an elongated curved tubular member, an outwardly extending flange at one end of said member, and a curved tube positioned in said tubular member in coextensive relation, said tube being rigid and said tubular member being semi-rigid, a short tube secured to the outer surface of the curved tube at one end and disposed within said tubular member adjacent the outwardly extending flange.
2. An ore-pharyngeal suction airway comprising an elongated curved tubular member, an outwardly extending flange at one end of said member, and a curved tube positioned in said tubular member in coextensive relation, said tube being rigid and said tubular member being semi-rigid, said tubular member including an upper wall that is thicker than the bottom wall.
3. A suction airway device comprising an elongated tubular member, and an elongated tube disposed within said tubular member, said tube partially filling said tubular member, said tubular member being semi-flexible and said tube being rigid, a short rigid tube secured alongside one end of said long tube and disposed within said tubular member, said tubes completely filling said tubular member.
4. An ore-pharyngeal suction airway comprising an elongated curved tubular member, an outwardly extendingfiange at one end of said member, and a curved tube positioned in said tubular member in coextensive relation, said tube being rigid and said tubular member being semi-rigid, a short tube secured to the outer surface of the curved tube at one end and disposed within said tubular member adjacent the outwardly extending flange, said tubular member including an upper wall that is thicker than the bottom wall, said tubular member being elliptical in cross section, said tube being cylindrical and positioned at one edge of said tubular member.
