ATTORN EYS United States Patent C) NASOPHARYNGEAL TUBE Vito Pagano, Jackson Heights, N. Y.
Application January 22, 1958, Serial No. 710,483 4 claims.l (cl. 1zs-34s) The present invention relates to a novel and improved nasopharyngeal tube for the treatment of the esophagus.
Objects and advantages ofthe invention will be set vthe invention, and together with the description, serve to explain the principles of the invention.
Of the drawings:
Figure l is a side elevation of a typical and preferred embodiment of the present invention;
Figure 2 is a schematic, longitudinal sectional view of the device shown in Figure l and in which the width of the parts has been proportionately exaggerated for a `clearer showing of the details of construction;
Figures, 4, 5,-6, 7 and 8 are cross sectional views taken on the lines 3--3 to 8 8 of Figure 1;
Figure 9 is a'fragmentary longitudinal sectional view of an end of certain of the tubes and showing a valve member in its open position; and
Figure l is a similar view showing the valve member in its closed position.
The present invention has for its object the provision of a novel and improved surgical device for the treatment of the esophagus and which may be held in position to seal the esophagus at its lower end while allowing tluid to be removed from or fed into the stomach, while blood or other tluids may be separately removed from the. esophagus or fluid medication may be supplied thereto. A further object is the provision of a single elongated multi-tube device which may be safely anchored and left in position one end being made fast by engagement with the cardiac orifice while the other end may be adjustably made fast and properly centered by an inflatable balloon which engages with the exterior of one or the other of the nasal openings through which the tube has been introduced through the esophagus and into the stomach, while allowing separate and selective communication with the stomach and the esophagus and with separate inatable members which may be inilated, one within the stomach and another in the esophagus but both at the cardiac oritice, and a third inatable member at the exterior of the nasal opening.
Referring now in detail to the present preferred and illustrative embodiment of the invention as shown in detail in the accompanying drawings, the surgical device of the present invention comprises a relatively long, narrow tubular member 10 formed of soft, non-deleterious, ilexible, liquid and gas tight material which may be subjected to thorough cleansing and sterilization, such as vulcanized gum rubber. Along its length, the principal tubular t ad ,A 2,854,982 Patented oct. 7, s
member is provided with other tubular members, some having a common wall with the principal tube and being formed into an exteriorly smooth surface throughout at least a portion of their common length, while in other parts, an extensible resilient, inflatable member is provided communicating with a tubular member at the outer end of each of which is provided an easily operated valve by which the inflatable member may be sealed olf and allowed to remain in its inflated condition. At their outer end the several tubular members are separated from each other so they may be easily manipulated and inflated or deflated, while another inllatable member is provided and may be adjustably moved along the outer end of the tubular member at a part where all of the tubes are joined to form a single elongated member.
The lower end 12 of the tube 10 comprising the stomach section is preferably about l/a inch in its outside diameter and has a smoothly rounded closed end 14. In this stomach section 12 the tube 10 is formed with a plurality of lateral holes 16, and these communicate with the main tubular passageway of the tube 18 and with the open ended tube 20, through which feeding fluids or medication may be supplied directly to the stomach, or through which stomach fluids may be removed.
At the upper end of the stomach section 12 is provided a small thin-walled, inflatable balloon 24, also formed of rubber and vulcanized to the tube 10, not in communication therewith, but separately communicating with an elongated tubular passageway 26 which terminates in a separate tube 28 provided at its outer end with a valve member 30.
Immediately above the gastric balloon 24, spaced very slightly therefrom and separately sealed to the tube 10 and to the tube 26 so as to have no communication therewith is a separate, slightly elongated, thin-walled inflatable esophageal'balloon 34 which has communication only with a thin parallel elongated tube 36 which, like tube 26, branches into a separate tube 38 at the upper end of the device where it is formed with a valve 40.
In the inflated condition of the balloon 24 within the stomach and the balloon 34 in the lower end of the esophagus they are adapted to press towards each other with the cardiac opening of the stomach gripped between them, thereby effectively closing off the esophagus and the stomach from each other.
Above the esophageal balloon 34, and extending throughout the remainder of the upper portion of the tubular member is a fine tubular member 44 which is provided with a plurality of lateral holes 46 and which is joined to the separated tubular member 48 at that portion of the device to lie outside of the patient's body, the outer end of tube 48 preferably left open and unvalved.
Adjacent the upper end of the common multi-tubular part 10 is a small toroidal balloon 52 which is formed as a thin-walled inflatable rubber balloon, the central opening corresponding to the exterior size of the tube 10 so that as the balloon 52 is inllated, the central portion of the balloon tightly grips the exterior of the tube 10 to hold the balloon in a given position of longitudinal adjustment. `Extending upwardly from the nasal centering balloon 52 is a small rubber tube 54, detached from the tube 10, through which air may be supplied to or released from the balloon 52 under control of the valve member 56.
The several valve members 30, 40 and 56 are all preferably of the form shown in Figures 9 and 10 yand may be substantially in accordance with the corresponding part of the patent to Stubbs No. 2,769,442 granted November 6, 1956, As shown, the end of the tube 28, 38 or 54 is provided with a slightly restricted portion 60 in the form of a depressed ring and is branched, one portion leading to a closed end 62 and the other to an open end 64, a thin wall 66 separating the closed and open ends. A small ball 68 of hard, durable material such closed position of Figure 10, merely by squeezing the tube 38 at one side of the ball or at the other side, thereby eiectively sealing the tube or allowing air to escape therefrom.
As shown in Figures 3, 4 and 5, the multi-tubular member is an exteriorly smooth, integral member, cellular in cross-section, and provided with four longitudinally extending, distinct tubular passages having a common wall member which is sufficiently thin to permit the tube 10 to remain flexible, but which prevents leakage of air or liquid from one passage to another.
In Figure..4, there is additionally shown the interior and exterior, thin, expansible walls of the nasal centering balloon 52.
Figure 6 shows the tubular members 18 and 26 as they appear within the esophageal balloon, while Figure 7 shows the stomach section 12 as it passes through the gastric balloon 24, and Figure 8 shows the stomach section 12 of the tube 10 below the gastric balloon 24.
In use, the balloons 24, 34 and 52 are deated and thel valves 30, 40 and 56 are in their open position. Suitably `sterilized and lubricated, the rounded end 14 of the tube 10 is pushed downwardly through one of the nasal openings nto and through the esophagus and through the cardiac orifice until the gastric balloon 24 is fully within the stomach. Then, air is supplied through passage 26 to inflate the balloon 24, after which valve 30 is closed and the tube is withdrawn until the gastric balloon presses against the upper opening of the stomach.
In this position, the esophageal balloon 34 is inated and its valve 40 is closed.
Thereafter, the tube 10 is subjected to slight tension, and the uninated nasal balloon 52 is pushed downwardly on the tube 10 until it engages the nostrilwith a slight pressure. In this position the balloon is inated and sealed oif by closing valves 56.
`In this condition of the device, the stomach section 12 is free within the stomach and fluids can be added or removed through the free lend of tube 20. Likewise, liquid may be removed from the esophagus through suction applied to the free end of tube 48, or Huid may be supplied to the esophagus through that free end of the tube, during all of Iwhich time the esophagus and stomach are isolated from cach' other and may be separately treated.
The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacriiicing its chief advantages.
What is claimed is:
l. A nasopha-ryngeal tube including in combination an elongated narrow tubular member having a plurality of noncommunicating passages throughout a major portion of its length and including an apertured member forming one end of the tube, adapted to extend into the stomach and communicating with an outlet at the other and outer end of the tube, a thin walled expandable balloon member attached to said tube and communicating with one of said passages to extend to a valved member whereby the balloon may be inflated and deflated within the stomach, a second thin-walled expandable balloon member adjacent the first balloon member attached to said tube and communicating with another of said passageways to extend to Ia valved member, a fourth one of the tubular passages being apertured adjacent the second balloon member and a third balloon member spaced from the second and communicating with a tubular member having an external valved end through which it may be inated or deiated.
2. A nasopharyngeal tube as claimed in claim 1 in which all of the valved members are adjacent the external end of the tube and are selectively operable.
3. A nasopharyngeal tube as claimed in claim 1 in which the first and second balloon members are adjacent each other to engage the cardiac orifice when the balloons are inated.
