STOMA IRRIGATING SYSTEM BACKGROUND OF THE INVENTION Patients who have had a colostomy operation are left with a stoma extending through the abdominal wall, from which waste material is discharged into a bag or container. In the care and treatment of many such patients, it is necessary routinely to irrigate the intestine and for that purpose it has been customary to use a cone, the apex of which is inserted into the stoma, with the apex having a hole therein connected to a tube, in turn connected to a source of irrigating fluid. With the cone inserted in the stoma, irrigating fluid may be introduced into the intestine for irrigating purposes. After a suitable length of time, the cone is removed, permitting irrigating fluid to drain out, cleansing the bowel. It has also been customary to provide a suitable bag adapted to be secured to the patient, into which such discharge is directed.

In the devices of the prior art designed to accomplish the foregoing irrigation, difficulty has been experienced in providing a cone which is soft and pliable, easy to clean, and which prevents the attached tube from penetrating into the stoma beyond the tip of the cone, a condition which can cause damage to the intestine. Difficulty has also been experienced in providing a structure which will permit the cone to be properly positioned in the stoma and yet which is arranged to catch and retain fluids draining from the intestine, including the irrigation fluid and other material which may be discharged therewith. The present invention is particularly designed to provide an irrigation system wherein a soft, easily 'cleanable cone may be easily, properly and safely positioned, and at the same time ample security for the retention of discharged fluid is provided.

BRIEF SUMMARY OF THE INVENTION Colostomy patients differ in a wide variety of ways.

Not only are the physical characteristics of each patient different, the size, shape, and location of the stoma varies significantly from patient to patient. According to the present invention, there is provided an irrigation system which may be used by the patient in several ways in order to effect proper irrigation of the intestinal tract, while at the same time providing meansfor catching and retaining fluids discharged after the irrigation has been accomplished. Thus, the present invention contemplates. a unique type of cone to facilitate irriga-.

ing the stoma, and through which self-sealing opening.

a tube connected to a source of irrigating fluidimay be inserted. When so inserted, the tube is directed through the base of the cone and into communication with an I aperture in the apex of the cone so that irrigating fluid is directed therefrom into the stoma and hence into the intestinal tractof the patient.

In some cases, or'occasionallyfrom timeto time with an individual patient, it may be advantageous to insert the apex of the cone into thestoma by inserting the apex through. the self-sealing opening mentioned above, and the present invention provides for this alternate method of use. In other cases, or occasionally from time to time with an individual patient, it may be advantageous to insert the entire cone, with its tube connected, into the bag through the open top and then to insert theapex of the cone into the stoma, and the present invention provides for this alternate method of use as well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the'drawings, there is shown an irri'gating system 10 which includes aretaining device 11 provided with means 12 to be secured to a belt 13 for holding the retaining device in position on the body of apatient 14. Theretaining device 11 is provided with acentral aperture 15 which surrounds thestoma 16 of the patient.

The irrigating system includes abag 20 of transparent or translucent plastic material having aninner wall 21 and anouter wall 22. Theinner wall 21 has an opening 23 sealed at its edges to theretaining device 11. Opposite the opening 23 in the inner wall of the bag is a selfsealing or self-closingopening 24 formed in the outer wall of thebag, with the opening 24 being directly opposite the center of the aperture15. I

Thewalls 21 and 22 are sealed together along their edges, but not at the top portion so that the walls may bev separated at the top to provide an access opening 25 large enough to permit the entry of thehand 27 of the patient. The walls of the bag may be folded at the top to close the opening 25, and the walls may be secured in closed position by means of bendablesoft metal clips 28.

Areservoir 30 is provided for use in conjunction with the apparatus thus far described, with the reservoir being connected to atube 31 extending through a hand-operatedvalve 32, with the valve serving to control the flow of fluid through the tube.

Thetube 31 is adapted to be used in conjunction with aseparate cone 33 of soft plastic material, with the cone having a hole at its apex and being provided with a relatively rigid diaphragm-like member 35 at its base. The diaphragm has a guide opening 36 extending therethrough and aguide cylinder 36a aligned therewith and extending along the axis of the cone. The diaphragm is snapped into position around the base of the cone by virtue of a mating of its outer edges with aninner recess 37 formed in the cone. Thehole 34 at the apex of the cone is designed so that the tip of thetube 31 will not pass through it, thus preventing the tube from accidentally entering the stoma. Thus, the inner diameter of the hole is less than the outer diameter of the tube. As a further insurance against the patient forcing the tube through the hole in the apex of the cone and into the stoma, the apex is provided with an in-turned flange 38 providing a shoulder which acts as a positive stop for the tube, thus preventing the tube from extending beyond the apex of the cone.

As indicated earlier, the device of the present invention may be used in either of three ways, one way being that illustrated in FIG. 3 wherein theclips 28 are loosened to permit the bag to be opened as shown at 25 and the hand of the patient inserted into the opening to position thecone 33 in the stoma. After the cone has been so positioned, thetube 31 is inserted through the opening 24 in theouter wall 22 of the bag, through the guide opening 36 to the opening 34 in the apex of the cone. The tube cannot be pushed beyond the apex of the cone as it has a larger diameter than the opening 34. Thus, the tube cannot be pushed beyond the cone into the stoma, which might injure the patient. With the tube and cone so positioned, thevalve 32 may be' opened and irrigating fluid will flow into the intestinal tract. When the irrigation has been completed, the cone is withdrawn from the stoma and the tube is withdrawn from the cone. At this point the opening 24 will automatically seal and the cone may be withdrawn from the bag and the latter closed by means of the clips 38. Fluid released by the irrigation process will then flow into thebag 20.

An alternate method of use of the bag which a patient may employ from time to time is shown in FIGS. 1 and 2 wherein thetube 31 is inserted through thediaphragm 35 into thecone 33 to position the end of the tube at theopening 34 in the apex of the cone. With the tube and cone so assembled, the apex of the cone is inserted through theopening 24 and moved toward the body of the patient to cause the apex of the cone to enter thestoma 16. When irrigation has been completed, thevalve 32 is closed and the tube and cone removed simultaneously to permit fluid to drain into the bag. The opening 24 will automatically seal to prevent the stoma discharge from following the apex of the cone when it is removed from the opening.

Still another method of using the apparatus of the present invention and probably the one that will most frequently be employed, is to assemble the tube and cone as shown in FIG. 1 and then insert the same so assembled through the opening-25 in the top of the bag after first releasing theclips 28. The hand of the patient can guide the cone and tube into the opening of the bag and insert the apex of the cone into the stoma. After being so inserted, thevalve 32 is opened and irrigation proceeds. During irrigation, the cone may be held in place by hand, which may be either inside or outside of the bag. When irrigation has been completed, the cone and attached tube are removed through the opening 25 which can then be closed by folding the top half of the bag and securely bending thesoft metal clips 28 to hold the bag in closed, folded position. The irrigating fluid and other bowel contents which will be expelled after the cone has been removed will flow into the bag.

One of the important features of the present invention is the fact that thecone 33 is made of soft plastic material. Thus, it will neither injure nor cause pain to the patient when it is inserted into the stoma. The cone is sufficiently flexible so as to adapt itself to the contours of the stoma and thus not only assure a good seal, but also assure the comfort of the patient. If the cone were made entirely of soft material, it would not possess sufficient strength to be inserted at least partially into the stoma and held there firmly enough to effect a seal. Thus, according to the present invention, the base of the cone, i.e., thediaphragm 35, is made of relatively stiff plastic material. As the diaphragm is snapped onto the base of the cone it is in contact with the entire circumference of the base and provides support at that end sufficient to permit insertion and retention of the apex of the cone. Because thediaphragm 35 may be snapped onto and off of the base of the cone, cleaning of the interior of the cone is made possible.
