Minn.
Application May 2 2, 1947, Serial No. 749,834 In Great Britain May 1, 1944 Section 1-, Public Law 690, August 8, 1946 Patent expires May 1', 19.64

contents of the obstructed bowel and thus relieves the distended condition, which frequently causes death, until the bowel either recovers-its physical and functional condition or until itis again restored to normal by surgery.
The practice of intubation has been known for some time but prior to my invention there was considerable difficulty in directing the apparatus into the pyloricsphincter, and frequently such attempts were unsuccessful. Such practices have included the use of wires extended through the length of the tube in the attempt .to direct the end of the tube into the pyloric sphincter or by weighting the end of the tube with the intent that it should find its Way by gravity into the duodenum. An example of the latter is disclosed in British Patent No. 330,855, dated October 15, 1929.
In the apparatus which I have designed, and which overcomes many of the objections inherent in intubation devices constructed prior to my invention, the intubation tube is provided at its lower end with what I term a gravity director head that carries the weighting substance and is considerably more flexible than the material of the tube proper so that it will readily find its Way into and below the duodenum. Thus-the tube may be drawn into the lowest accessible point of the anatomy, and by regulating the'positi'onand posture of the patient any particular part of the alimentary tract may be reached.
In the accompanying drawing, which illustrates a preferred embodiment of the invention,
the single figure is a diametrical sectional elevation through the lower end parts of the apparatus.
Referring to the drawing more particularly and by reference characters E designates a more. 'or
less conventional intubationtube which is of any desired length and maybe connected at its upper end to suitable-suction or supply means (not shown) depending upon whether substances are to be removed from or applied to the areas to be treated. This tube is connected by a suitable coupling or adaptor El to a tube section or extension EZ that terminates in a connector E3. The parts El and E3 are made of any suitable material and it is only necessary that the connector E3 bemade of such material as will not :amalgamate with the mercury with which it comes in contact if mercury is used for weight purposes. The tube E (and E2) must of course be sufficiently flexible to permit following the desired circuitous course, but must also be of such body and stiffness as not to collapse when suction is applied. This tube is provided at its lower extremity with a lateral orifice A through which the substances are drawn into the tube or expelled from it.
The directorhead C depends from the connector E3, to which its neck portion is tightly secured, and is constructed of thin very flexible material such as rubber to form an impermeable flaccid sack. To carry out its gravitational directing objective this sack G contains some heavy fluid or mobile substance D, such as mercury,- lead shot, or small metallic spheres, which is of course sealed from'any contact with the interior of the tube or with parts of the body.
Theysack is capable of adapting itself closely to the surface contours of the part of the body with which it is brought into contact so that when the director-head has drawn the apparatus to the position of the sphincter the heavy load of the sack presses upon the sphincter and the heavy fluid pressure in the thinwalled sack presses a small part of the wall of the sack through a small opening in the sphincter and progressively draws more-of the sack into and through the sphincter :untilthe whole sack has passed the sphincter drawing the intubator apparatus behind with its suction or delivery orifice and the pneumatic expanding. plug.
'When necessary the metallic content of the sack enables the progress and position of the apparatus to 'bE'ObSGPV'Gd. and determined with the aid :of Xeray andfluoroscope.
.:Imorderrtoretainrhe "orifice end of thetube in any desired advanced position, and to form a dam or closure above any given section of the intestine, there is provided a flexible stop or plug in the form of a balloon or thin rubber bag B, the upper and lower ends of which are sealed with respect to the couplings E2 and E13 by suitable tape or windings, as indicated. This bag is of course deflated when introduced but is inflated as may be desired by air forced into it through a small tube F running parallel with and adjacent to the tube E. When the intubation has been completed this bag is deflatedto facilitate the removal of the apparatus.
