Patented Sept. 20, 1932 JAMES W. KENNEDY, OF CANTON, OHIO :oILA'ron Application fiIed May 13,
This invention relates to improvements in dilators and more particularly to an instrument for expanding the sphincter muscles in the rectum. This invention is an improvement of my co-pending application, Serial Number 487,042, filed October 7, 1930. i
The principleobject of the invention is to provide a device of this nature which will expand the sphincter muscles of the rectum without causing friction and without Cltl11- age and pain.
Another object of the invention is the provision of a device for treating constipation, piles, poor circulation and other rectal diseases.
Another object of the invention is to provide a device which will expand the rectum throughout its length in an even and uniform manner.
Still another object of the invention is to provide an instrument of this character consisting of a tube made from pliable material and adapted to be inserted in the rectum and a plug for expanding the wall of said tube.
Still a further object of the invention is to provide an instrument "of this kind com prising a pliable tube adapted to fit in the rectum, a series of wire guides longitudinally disposed in said tube and a plug for forcing said wire guides and the wall of the tube outwardly.
A further object of the invention is to provide means to support the dilator on the body of the patient.
Another object of the invention is to prevent a pressure and suction being formed when operating the dilator.
Other objects of the invention will appear as the disclosure progresses. The drawing is intended to merely indicate a possible embodiment of the invention. It is obvious that the actual needs of manufacture may necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embodiment illustrated, but rather to define such limits in the appended claims.
For a more general understanding of the invention attention is called to the drawing. In this drawing like reference char- 1931. Serial NO. 537,172.

Figure 9 is a detail showing a portion of the guide wires in place.
Figures 10 and 11 are views of different size plugs.
Referring now to the drawing in. detail numeral 1 designates the tube made from soft pliable material such as rubber. The tube is closed at the top and at the bottom thereof there is provided a flange 2 which fits into a groove 3 of the disk 4. This disk is made of sponge rubber and is cemented in a cavity 5 of thecup 6 which is also made of rubber. Running parallel with the tube are two sets of wire guides 7 and 8 the bottom ends of which are bent at right angles as at 9 and fit in the radially disposed slots 10 of the disk 1 as clearly shown in Figures 7 and 8. The tops are rigidly tied together in a manner as follows. Numeral 11 designates a short section of a rubber tube. Fitting in the central bore thereof is the bent over end 12 of one of the sets of fifteen guide wires 8. Fitting over the collection of the wires 7 is a rubber sleeve 13 and spaced around this sleeve are the other set of fifteen of the guide wires indicated by numeral 8. Tightly fitting over this structure is a rubber thimble 14 which rigidly ties the ends of the Wires 7 and 8 together. The purpose of bending the end 12 of one of the wires 8 and passing the end into the bore of the tube 11 is to lock the tube 11 and sleeve 13 and prevent them from working loose. Around this structure is placed the pliable tube 1.
In Figure 9 is illustrated the method of assembling the guide wires. The set of wires 7 is shown inserted in the sleeve 13 while for the sake of clearness, only two of the set of wires 8 are shown surrounding the outside of the sleeve. The rest of the wires will obviously be placed in position to complete'assemblage. The wire 8 at'the left has its top end bent over and fitting into the bore of the tube as heretofore described, 1
In the center of cup 6 is a tapered hole 15 for allowing theplugs 16 and 17 to enter the interior of the dilator. Fastened to the cup are a pair of eyes18 through which pass the cords 19 which are tied to the belt 20 to be worn around the Waist of the patient.
The operation ofthis device is as follows: the tube is first placed in the rectum and one of the plugs 16 or 17 is inserted therein. As
the plug moves inwardly the tube will GX'V pand and enlarge the membrane of the rec tum. As statedheretofore the tube is made from pliable material so it can readily expand without any undue strain of the operator. The plug does not come in contact with the wall of the tube but slides on the wire guides 7 and 8 and as the guides spread outwardly the tube distends correspondingly. By this arrangement an even expansion of the tube is brought out. Otherwise there would always be a sharp difference in the diameter of the tube between the part which is already filled up with the plug and the part which is not. The portion of the tube which is filled up with the plug would naturally be larger in diameter while at the end of the plug there would be a marked restriction in the diameter of the tube.-
The plugs are tapered at the ends 21 and bulge out in the center 22. A' variety of size plugs can be used to suitthe needs of the patient. of the plugs are longitudinal bores 23. The reason for these bores is to prevent a suction or pressure forming when operating the div lator.
The purpose of providing the means to attach the device to the body of the wearer is to enable the patient to be treated without any interference and'while engaged in his regular business activities. The device can be carried around and worn without any discomfort to the patient. The dilators can be made of various sizes to suit the needs of the patient. The base of the dilators are made of two sections 4 and 6 and cemented together by the cement 24 forming a unitary structure. T Having described my invention, I claim:
