(01. 128-276) My invention relates generally to gastro-intescomes redistended while the duodenum tube is in tina'l treatment systems, and has for its object place, necessitating a partial removal of the tube the production of a new and improved system to permit escape of stomach gas.

The duplex tube The duplex tube 2, Figs. 1 to 4, is preferably molded rubber of a sufiicient over-all length (about four feet) to enable it to be located and used as clearly indicated in Fig. 1.
Figure 2 shows a full scale outside view of the internal end of an adult size duplex tube, while Fig. 3 shows a section taken at the line 3-3 of Fig. 2, showing the separation of the internal portion of the tube into duodenum and stomach passageways 3| and 4|.
Figure 4, taken on the center-line 44 of Fig. 3, shows that the stomach passageway 4| ends some distance from the end of the tube, only passageway 3| continuing in the duodenum extension 30 of the tube.
Figures 2 and 4 clearly show the perforations 33 through which passageway 4| communicates with the stomach, as well as the perforations 34 through which passageway 3| communicates with the duodenum.
In Fig. 1, the head of the patient is denoted by the numeral 5, with 6 and I denoting a nasal passage and the throat respectively. The tube 2 is passed through the nasal passage 6, the throat I, and through the esophagus 8 into the stomach 9, with the duodenum extension 30 passing through the pyloric orifice l0 into the upper portion of the duodenum II. Outside communication with the passageways 3| and 4| is through the duodenum and stomach branches 3 and 4, respectively, Fig. 1.
With tube 2 in place as shown in Fig. 1, the duodenum and stomach are vented separately through branches 3 and 4, respectively, which may be both left open during and shortly following insertion of the tube to permit escape of the gases of distention. Breathing may take place freely through the remaining nostril; moreover, the patient may swallow in the usual way.
Intestinal deflation In order to assist in an alleviation of the distended and blocked intestinal condition, as well as to remove the toxic liquid, and to enable the attendant to note the rate at which gas is removed from the duodenum, the suction and receiving bottles I 8 and 25 are provided and interconnected as shown. Suction bottle l8, initially nearly full of water or other suitable liquid, is stoppered and connected with receiving bottle 25 by the glass discharge tube 2|, rubber tube 22, and inlet tube 23. Vent tube 20, long enough to extend above the level of the liquid i9 when the suction bottle is inverted, is connected by a rubber tube to the duodenum branch 3 of duplex treatment tube 2, by way of the Y tube l5. The tubing l6 connected to the lower arm of branch tube I5 is normally closed by clamp H, which clamp may be transferred to branch 3 or 3, under circumstances to be discussed subsequently.
When the above preparations have been made, the suction bottle I 8 may be inverted and elevated above the level of receiving bottle 25, causing liquid to flow from suction bottle l8, through tubes 2| to 23, into receiving bottle 25. Bottle 25 is vented to atmosphere by tube 24. This flow causes the air in bottle l8 above the level of liquid l9 to become somewhat rarefied, whereupon the fiow ceases except as gas is drawn through passageway 3| in tube 2 from the duodenum The suction thus effected according to the difference in elevation between bottles l8 and 25 is applied through branch. 3 and contained passageway 3| to the duodenum. The rate at which the liquid level recedes in bottle l8 and builds up in bottle 25, indicates somewhat closely the rate at which gas is being removed from the duodenum. It should be kept in mind that 5 the tubing interconnecting bottles l8 and 25 is sufficiently small so that it remains filled with liquid to prevent air from bubbling upward into the upper bottle from the lower.
The capacity of each of the bottles l8 and 25 may be on the order of four quarts, enabling one filling to last for a considerable time, as the liquid ordinarily descends drop by drop, as indicated at 26, into accumulated liquid 21. The drops, however, are more often further apart than is indicated in the illustration.
The removal of the toxic liquid from the duodenum stops the previous rapid passage of the poisonous substance into the body, while the gently deflated condition of the duodenum resulting from the mild suction applied thereto as illustrated and as above described permits the entire portion of the small intestine above the distension-induced blockade to return to normal size, which results reliably in alleviation of the blocked condition, asone iturn after another of the small intestine loses its gas of distention, giving room for the blocked or isolated section to rotate back to normal position and open the blockade. 30
The removal of gas and toxic matter from the duodenum is often interfered with by plugs of mucous and other particles lodging in the perforations 34 (Figs. 1, 2, and 4). When the stoppage at the perforations 34 becomes great enough to interfere with the removal of gas and regurgitated liquid from the duodenum, the level of liquid l9 becomes more or less stationary. When this occurs, the clamp I! may be transferred from tube I6 to tube 3' to enable the duodenum'passageway through tube 2 to be cleaned by applying a suitablehand pump to tube l6. At this point, it may be noted that perforations 34, while collectively larger [than the area of the duodenum passageway in the treatment tube, are each enough smaller so that any particle which will pass through a perforation will pass readily through the tube.
After the perforations have been unplugged, by alternate pressure and suction surges from the 5, pump, clamp I! may be transferred back to tube I6 to permit the further removal of gas and fluid by gentle and continuous suction.
Stomach venting and feeding In order to maintain the stomach continuously vented while permitting liquid, with or with-- out nourishment, to be supplied slowly to it, the stoppered and inverted feeding bottle I2 is provided for connection to the stomach branch 4 of the treatment tube 2. Feeding bottle I2 is v'ented to the atmosphere by tube |4, long enough to extend above the level of the liquid. Theliquid may flow from the submerged tube I3 into the interconnected branch 4, and thence by way of stomach passageway 4| (Figs. '3 and 4) andperforations 33 (Figs. 1, 2, and 4) to the stomach 9. The stomachmay thus perform its normal absorptive functions. Screw clamp 50 may be adjusted to control the rate at which liquid is supplied to the stomach.
The elevation of feeding bottle |4 above the stomach is preferably small, whereby any gas accumulating inthe stomach during feeding -may escape by flowing intermittently back up the stomach passageway 4| in the tube against the slight feeding pressure, bubbling up through the liquid in the bottle I2 to escape to atmosphere through vent tube 14. Moreover, the discharge of substantial amounts of gas from the stomach may be noted by this bubbling in bottle I2. The attendant thus has continuous visual notification of the progress of intestinal and stomach venting and of the feeding.
In addition to providing nourishment for the system, the stomach feeding supplies the necessary liquid to compensate for losses of body fluids. Distilled water may be fed into the stomach and readily absorbed thereby.
At intervals during the giving of the treatment, gas pockets in the intermediate intestinal portion may be opened into the duodenum causing a sufiicient surge to carry toxic liquid and gas back up through the pylorus into the stomach. The peristaltic action from stomach to duodenum may be depended on to pass the toxic liquid back to the duodenum to permit its removal by way of the duodenum passageway of the tube 2. The attendant however should remove the feeding bo-ttle H at this time and replace the liquid therein with a. fresh supply, for enough back flow of toxic liquid from the stomach may occur to cause contamination. The fresh liquid flowing into the stomach assists in washing the toxic liquid back into the duodenum to be removed as above described.
Modified forms of duplex tube Figure 5 shows a section of a desirable modification of the duplex treatment tube, indicated generally by the reference character 500, while Fig. 6 shows a sectional view taken at the line 85-5 of Fig. 5.
The stomach perforations in the tube wall are indicated at 533, and the duodenum extension at sea. The duodenum. and stomach passageways are indicated in Fig. 6 as WI and 54!, respectively.
Figures '7 and 8 show a second desirable modification of the duplex treatment tube, while Figs. 9 and 10 show a third.
The modified forms of the duplex treatment tube are similar to the preferred embodiment indicated at 2 in Figs. 1 to 4, except in crosssection. Generally, the smaller and more nearly round the tube, the easier it can be inserted. Figures 1 to 4 and Figs. 7 and 8 show tubes circular cross-section, but in these tubes the inclusion of the smaller stomach passageway within the circular outline containing the duodenum passageway narrows the latter passageway somewhat in one direction, possibly rendering it more susceptible to occasional stoppage by food particles and the like which may coalesce into a larger mass after being drawn in from the duodenum. Since the stomach passageway need not be large, it may be contained in a small tube adherent to the main tube and lying parallel to and outside the circular outline of the duodenum passageway as in Figs. 5 and 6, or it may be of crescent-shaped cross-section as in the modification shown in Figs. 9 and 10. These arrangements prove quite satisfactory provided the tube is properly inserted in the nostril, as the somewhat flattened or oval shape of the tube conforms rather closely to the shape of the nostril. The throat and esophagus pass any of the tubes quite readily, as they are of small section compared to relatively large objects which may be swallowed readily.
A feature. of the duodenum extension is that the tip thereof is weighted by the weight 28 to facilitate the insertion thereof into the duodenum. When the patient is turned on his right side, with the tube inserted as far as the stomach, the weighted tip of the duodenum extension 30 falls easily through the pylorus and passes into the duodenum. as the tube is gently urged into final position.
The length of the duodenum extension, while not critical, should be about five inches in the normal adult size, and the farthest duodenum perforations 34 should be not more than two and one-fourth inches from the tip, keeping in mind that the tube cannot be easily passed into the duodenum much more than this distance because of the backward and downward bend in the first or superior portion to join the second or descending portion. No perforation of the duodenum extension may be permitted to remain on the stomach side of the pyloric orifice, for the suction applied as hereinbefore pointed out is then applied also to the stomach. This causes air to be swallowed more or less continuously, not only giving a false reading in the liquid level in the suction and receiving bottles l8 and 25, but also reducing and more or less nullifying the suction as applied to secure deflation of the duodenum. It may be noted, however, that the presence of a stomach-passageway perforation 33 in the esophagus ordinarily has no adverse eifect on the treatment.
What I claim is:
1. A duplex gastro-intestinal treatment tube for insertion through the esophagus into the stomach, said tube containing parallel passageways, cne passageway adapted to terminate in the stomach when the tube is in position and being in open communication with the stomach interior through a. perforation in the wall of the passageway, said tube having an extension adapted to carry the other passageway into the duodenum and into open communication therewith when the tube is in position, the wall of said other passageway being imperforate in the portion thereof lying within the stomach.
2. In a gastro-intestinal treatment system, tube means adapted to afford a passageway from the outside to and in open communication with the duodenum through a nasal passage, the throat, the esophagus, and the stomach, said tube means adapted to afford a parallel passageway from the outside into and ending within and in open communication with the stomach.
