This invention is for an irrigator drain for ostomy patients, particularly for irrigating into the stomas of colostomy patients. It is characterized by the provision of a stoma cone fixed to the outer or rear wall of a drain tube whereby to facilitate the application of the irrigator into the stoma; also to features of novelty and improvement which make the irrigator low in cost of manufacture and economical for disposal after a single use.

Heretofore, various devices and appliances have been used for irrigating purposes, including my inventions desclosed in U.S. Pat. Nos. 2,928,393, 3,292,625, and 3,672,370. Also in the prior art is an irrigator having a stoma cone which said cone is advertised to sell about 4.00 dollars to 5.00 dollars. These I consider to be relatively high cost and also objectionable because they are designed to be re-used and must be washed and sterilized after each use.
Another object of my invention is, therefore, to provide an irrigator unit of such new and improved construction it can be manufactured and sold below the cost of present irrigators.
Another object is to provide a new and improved irrigator of such low cost as to make it disposable after each use, thereby not only benefiting the patient but being most helpful to hospitals and institutions which handle irrigators and are happy to dispose of these irrigators as well as other appliances and equipment adapted for disposal.
Other objects and advantages of my invention will be appreciated by those skilled in this art as the invention becomes better understood by reference to the followin g description when considered in connection with the accompanying drawings, in which FIG. 1 illustrates the usual method used by a colostomy patient to irrigate the bowel;
FIG. 2 is an isometric view of a stoma cone such as is used with my invention;
FIG. 3 is a front view of an irrigator drain illustrating an assembly of parts which comprise a disposable irrigator of my invention;
FIG. 4 is a vertical section taken on the section line 44 of FIG. 3; and
FIG. 5 is a diagramatic view illustrating an assembly of parts in the use of my invention as applied to a patient.
It will be understood that these drawings are diagramatic as to sizes and shapes for the purpose of illustrating the principles of my invention.
wall 9. When the drain tube is a polyethylene material it is preferred to also make the stoma cone of the same or similar material so that the cone may be united entirely around its rim 14 to the film by conventional heat sealing, thus fixedly connecting the stoma cone to the drain tube. When the stoma cone is located inside the drain tube as shown in the drawings a small slit 16 is made in the rear wall centrally within the rim 14 of the cone. The catheter 15 is pushed through this slit opening and also through the tightly fitting opening 19 at the point of the cone and into the stoma as shown in FIG. 5. The catheter connects with a tube 17 to an enema bag 18 or any suitable source of water supply. In actual practice the cone is inserted into the open end of the stoma and spreads the stoma sufficiently to make a water-tight connection without harm to the stoma, as illustrated diagramatically in FIG. 5. The catheter 15 is carefully pushed into the stoma a suitable distance as is well known in this art.
With my invention the stoma cone can be easily inserted into the'stoma 13 by reason of the fact that the rim 14 of the cone serves as a relatively wide hand grip which may be easily manipulated. The rim 14 also prevents the cone being inserted farther than necessary into the stoma.
It is preferred to hold the drain tube in position on the abdomen 19 of the patient by the use of a low cost belt such as 20, of heat fusible material as in my U.S. Pat. No. 3,695,268 with the ends 21 of the belt heat sealed to the gasket and also to the drain tube if desired. Also as shown in FIG. 4, I provide a short elastic piece 22 for tension at one end of the belt and cinch Referring more particularly to the drawings, my invention is characterized by the provision of a stoma cone designated generally by 6 preferably disposed inside the drain tube which is designated generally by the reference numeral 7 and having what I term front and rear sides or film walls 8 and 9, respectively. The drain tube may be of any low cost material and preferably 1 use a thin polyethylene film suitable for heat sealing to other components of the irrigator, as will be presently noted. The bottom end of the drain tube is open as at 10 so that the discharge falls into the commode or other receptacle. The drain tube has a stoma-receiving opening in its front side near the top surrounded by .a gasket 11 having a relatively large central opening 12 registering with the stoma-receiving opening in the drain tube. The gasket may be of suitable material but preferably I use a plastic ring which may be heat sealed to the front wall of the drain tube. The stoma 13 enters the opening 12 as noted in FIG. 5. The stoma cone 6 is preferably located inside the drain tube and has a flat annular rim 14 which is fixed to the inner side of the rings 23 for locking the free ends of the belt to hold the drain tube taught on the patient.
Low cost of the irrigator is further effected by the improved stoma cone. To this end I employ low cost aluminum molds to form thin flat sheets of polyethylene or other suitable material, wood, plaster, or plastic into numerous cones. The cones adjoin sufficiently to allow for the rims 14 to be die cut from the sheet. The cone shapes are formed by conventional vacuum techniques. This low cost is an important factor in making the irrigator available as a disposable article.
The stoma cones can also be made by injection molding but the high mold cost can only be justified when the quantity is large enough.
The irrigating function is well known in this field and after completing the supply of fluid into the stoma the catheter will be removed and the discharge from the stoma will be into the drain tube.
It will be understood that in the practice of this invention changes may be made in details and embodiments without departing from the spirit and scope of the invention as expressed in the appended claims, in which I claim:
1. An irrigator drain with stoma cone for ostomy patients comprising, in combination with a catheter tube adapted for connection to a source of liquid supply for the irrigation action, a drain tube having front and rear side walls of flexible film, the front wall having a stomareceiving opening, a cone positioned within the drain tube in alignment with the stoma-receiving opening and with its pointed end adjacent to said opening, the cone having at its wide end an annular outwardly extending peripheral wall fixed to the rear film wall of the drain tube and adapted to be grasped by hand from the rear catheter action.
I 2. An irrigator as set forth in claim 1, wherein the cone is positioned entirely within the drain tube and the annular wall of the cone is fixed to the inner side of the rear film wall of the drain tube, and wherein said rear wall of the drain tube has a relatively small slit opening for passage of the catheter tube into the cone.
